Definitions

  • TECHNICAL FIELD This invention relates generally to methods and compositions for the treatment for amelioration or prevention of sepsis, severe sepsis, severe sepsis with septic shock, critical illness myopathy and critical illness polyneuropathy and particularly to the use of a combination of parenteral or enteral feeding with a carboxylic acid.
  • Critical illness is defined as any acute medical condition necessitating vital organ support without which death would be imminent. Whether evoked by sepsis, severe sepsis, septic shock, trauma, major surgery, or other critical illnesses, patients can suffer from critical illness myo- pathy and/or critical illness polyneuropathy, a clinical manifestation referred to as intensive care unit (ICU) acquired weakness (ICUAW) (Kress JP, Hall JB 2014 NEJM 370(17): 1626-35). Prevalence of ICUAW varies according to the study population, but up to 80% of ICU patients appear to suffer from muscle wasting and/or muscle weakness.
  • ICU intensive care unit
  • ICUAW intensive care unit acquired weakness
  • ICUAW is associated with impaired weaning from mechanical ventilation, delayed rehabilitation and prolonged hospitali- zation, late death and greater impaired functional outcome of survivors.
  • Parenteral provision of macronutrients during acute critical illness does not prevent muscle weakness and may in fact exert deleterious effects via further suppression of autophagic myofiber quality control (Hermans et a I, 2013 Lancet Respir Med l(8):621-9; Derde S et a I, 2012 Crit Care Med 40(l):79-89).
  • an object of the present invention to provide methods and compositions for treating sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy. It is another object of the invention to decrease the morbidity and more prefer- ably the muscle weakness associated with sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy.
  • the above methods are used for the treatment of symptoms associated with a critical illness which includes, but is not limited to sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy.
  • This invention was based in part on the discovery that critical illness and/or sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy can be pre- vented, treated or cured, at least to a certain extent, by a composition containing a carboxylic acid, more preferably 3-hydroxybutyric acid in combination with enteral or parenteral feeding.
  • a composition containing a carboxylic acid, more preferably 3-hydroxybutyric acid in combination with enteral or parenteral feeding.

Description

3-HYD ROXYBUTYRATE ALONE OR IN COMBINATION FOR USE IN THE TREATMENT OF CRITICAL CARE TREATMENT
TECHNICAL FIELD This invention relates generally to methods and compositions for the treatment for amelioration or prevention of sepsis, severe sepsis, severe sepsis with septic shock, critical illness myopathy and critical illness polyneuropathy and particularly to the use of a combination of parenteral or enteral feeding with a carboxylic acid. BACKGROUND
Critical illness is defined as any acute medical condition necessitating vital organ support without which death would be imminent. Whether evoked by sepsis, severe sepsis, septic shock, trauma, major surgery, or other critical illnesses, patients can suffer from critical illness myo- pathy and/or critical illness polyneuropathy, a clinical manifestation referred to as intensive care unit (ICU) acquired weakness (ICUAW) (Kress JP, Hall JB 2014 NEJM 370(17): 1626-35). Prevalence of ICUAW varies according to the study population, but up to 80% of ICU patients appear to suffer from muscle wasting and/or muscle weakness. ICUAW is associated with impaired weaning from mechanical ventilation, delayed rehabilitation and prolonged hospitali- zation, late death and greater impaired functional outcome of survivors. Parenteral provision of macronutrients during acute critical illness does not prevent muscle weakness and may in fact exert deleterious effects via further suppression of autophagic myofiber quality control (Hermans et a I, 2013 Lancet Respir Med l(8):621-9; Derde S et a I, 2012 Crit Care Med 40(l):79-89).
However, despite the major advances of the past several decades in the understanding of critical illnesses including sepsis, severe sepsis, severe sepsis with septic shock, critical illness myopathy and critical illness polyneuropathy, there is still no effective treatment to treat these conditions or reduce the symptoms such as ICUAW associated with them. There is, therefore, a need for new methods and compositions for the treatment of sepsis, severe sep- sis, severe sepsis with septic shock, critical illness myopathy and critical illness polyneuropathy.
SUMMARY
It is, therefore, an object of the present invention to provide methods and compositions for treating sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy. It is another object of the invention to decrease the morbidity and more prefer- ably the muscle weakness associated with sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy.
In accordance with another aspect of the instant invention, the above methods are used for the treatment of symptoms associated with a critical illness which includes, but is not limited to sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy.
This invention was based in part on the discovery that critical illness and/or sepsis, severe sepsis, septic shock, critical illness myopathy and critical illness polyneuropathy can be pre- vented, treated or cured, at least to a certain extent, by a composition containing a carboxylic acid, more preferably 3-hydroxybutyric acid in combination with enteral or parenteral feeding. Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

DETAILED DESCRIPTION Definitions In describing the present invention, the following terms will be employed, and are intended to be defined as indicated below.
The caloric target in the meaning of this application is a caloric target calculated as the caloric need times the Corrected Ideal Body Weight. The formula for calculating Ideal Body Weight for a female patient is 45.5 + [0.91x (height in cm - 152.4)] and for a male patient 50 + [0.91 x (height in cm - 152.4)]. If BMI<18.5, the Corrected Ideal Body Weight is (Ideal Body Weight + Actual Body Weight)/2, if 27 > BMI > 18.5, the Corrected Ideal Body Weight is the Ideal Body Weight, if BMI > 27, the Corrected Ideal Body Weight is the Ideal Body Weight x 1.2. The caloric need for a female patient > 60 years is 24 kcal/kg/day, the caloric need for a male patient > 60 years is 30 kcal/kg/day, the caloric need for a female patient≤ 60 years is 30 kcal/kg/day, the caloric need for a male patient≤ 60 years it is 36 kcal/kg/day.
It must be noted that the caloric calories required for pediatric ICU patients differ from adults, for instance caloric calories required for pediatric ICU patients is 100 Cal/kg/day for a body weight 0-10 kg, 1000 + (50/kg over 10 kg) for a body weight of 10-20 kg, and 1500 + (20/kg over 20kg) for a body weight > 20 kg. It has to be understood that likewise the claimed ratio chemical energy providing macronutrient or caloric organic compounds in the medical compositions are adaptable for pediatric ICU patients.
It must be noted that, as used in this specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the content clearly dictates otherwise. The term "about," particularly in reference to a given quantity, is meant to encompass deviations of plus or minus five percent. The terms "subject," "individual," and "patient," are used interchangeably herein and refer to any animal, including, without limitation, humans and other primates, including non-human primates such as chimpanzees and other apes and monkey species; farm animals such as cattle, sheep, pigs, goats and horses; domestic mammals such as dogs and cats; laboratory animals including rodents such as mice, rats and guinea pigs; birds, including domestic, wild and game birds such as chickens, turkeys and other gallinaceous birds, ducks, geese, and the like, and transgenic animals. In some cases, the methods of the invention find use in experimental animals, in veterinary applications, and in the development of animal models for disease. Preferably, the patient is a human.
The term "pa rente rally" or "parenteral administration" as used herein means administration of a product by means of injection, such as injection into a vein (intravenous administration), into a muscle (intramuscular administration), under the skin (subcutaneous administration) or intraperitoneal injection.
The term "enterally" or "enteral administration" as used herein refers to the introduction of a product into the stomach or intestines, such as by tube feeding or by peroral administration (such as eating). In particular enteral administration refers to the introduction of a product into the stomach or intestines via a tube.
The term "Sepsis" has been described under 2016/17 ICD-10-CM Diagnosis Code A41.9 in the ICD-10-CM Diagnosis Codes and means the presence of a bacteria or their toxins in the blood or tissues.
The term "Severe sepsis" has been described under 2016/17 ICD-10-CM Diagnosis Code R65.2 in the ICD-10-CM Diagnosis Codes and means sepsis associated with organ dysfunction distant from the site of infection.
The term "Severe sepsis with septic shock" has been described under 2016/2017 ICD-10-CM Diagnosis Code R.65.21 and means life-threatening low blood pressure (shock) due to sepsis The term "Critical illness myopathy" has been described under 2016/17 ICD- 10-CM Diagnosis Code G72.81 in the ICD-10-CM Diagnosis Codes. The term "Critical illness polyneuropathy" has been described under 2016/17 ICD-10-CM Diagnosis Code G62.81 in the ICD-10-CM Diagnosis Codes. Both Critical illness myopathy and Critical illness polyneuropathy refers to a syn- drome of diffuse, symmetric, flaccid muscle weakness occurring in critically ill patients and involving all extremities and the diaphragm with relative sparing of the cranial nerves. Critical illness myopathy and Critical illness polyneuropathy have similar symptoms and presentations and are often distinguished largely on the basis of specialized electrophysiological testing or muscle and nerve biopsy.
In its broadest sense, the term a "critically ill patient", as used herein refers to a patient who has sustained or are at risk of sustaining acutely life-threatening single or multiple organ system failure due to disease or injury, a patient who is being operated and where complications supervene, and a patient who has been operated in a vital organ within the last week or has been subject to major surgery within the last week. In a more restricted sense, the term a "critically ill patient", as used herein refers to a patient who has sustained or are at risk of sustaining acutely life-threatening single or multiple organ system failure due to disease or injury, or a patient who is being operated and where complications supervene. In an even more restricted sense, the term a "critically ill patient", as used herein refers to a patient who has sustained or are at risk of sustaining acutely life-threatening single or multiple organ system failure due to disease or injury. Similarly, these definitions apply to similar expressions such as "critical illness in a patient" and a "patient is critically ill".
The term "Intensive Care Unit" (herein designated ICU), as used herein refers to the part of a hospital where critically ill patients are treated. Of course, this might vary from country to country and even from hospital to hospital and said part of the hospital may not necessary, officially, bear the name "Intensive Care Unit" or a translation or derivation thereof. Of course, the term "Intensive Care Unit" also covers a nursing home, a clinic, for example, a private clinic, or the like if the same or similar activities are performed there.
The term "lipid" refers to a fat or fat-like substance that is insoluble in polar solvents such as water. The term "lipid" is intended to include true fats (e.g. esters of fatty acids and glycerol); lipids (phospholipids, cerebrosides, waxes); sterols (cholesterol, ergosterol) and lipoproteins (e.g. HDL, LDL and VLDL).
The term "BMI" or "body mass index" refers to the ratio of weight (kg)/height (m2) and can be used to define whether a subject is underweight, normal, overweight, obese or severely obese. Typically, according to WHO criteria, a subject is underweight if he has a BMI<18,5; normal if he has a BMI of 18,5-24,9, overweight if he has a BMI of 25-29,9, class I obese if he has a BMI of 30-34,9, class II obese if he has a BMI of 35-39,9 and class III or severely obese if he has a BMI>40. As used herein, the terms "treatment," "treating," and the like, refer to obtaining a desired pharmacologic and/or physiologic effect. The effect may be prophylactic in terms of completely or partially preventing a disease or symptom thereof and/or may be therapeutic in terms of a partial or complete cure for a disease and/or adverse effect attributable to the disease. "Treatment," as used herein, covers any treatment of a disease in a mammal, particularly in a human, and includes: (a) increasing survival time; (b) decreasing the risk of death due to the disease; (c) preventing the disease from occurring in a subject which may be predisposed to the disease but has not yet been diagnosed as having it; (d) inhibiting the disease, i.e., arresting its development (e.g., reducing the rate of disease progression); and (e) relieving the disease, i.e., causing regression of the disease, (f) improving the condition of the patient (e.g., in one or more symptoms), etc.
The term "administration" as used herein refers to delivery of at least one therapeutic agent to a patient.
"Pharmaceutically acceptable or under food law acceptable salt" includes, but is not limited to, amino acid salts, salts prepared with inorganic acids, such as chloride, sulfate, phosphate, diphosphate, bromide, and nitrate salts, or salts prepared from the corresponding inorganic acid form of any of the preceding, e.g., hydrochloride, etc., or salts prepared with an organic acid, such as malate, maleate, fumarate, tartrate, succinate, ethylsuccinate, citrate, acetate, lactate, methanesulfonate, benzoate, ascorbate, para-toluenesulfonate, palmoate, salicylate and stearate, as well as estolate, gluceptate and lactobionate salts. Similarly salts containing pharmaceutically acceptable or under food law acceptable cations include, but are not limited to, sodium, potassium, calcium, aluminum, lithium, and ammonium (including substituted ammonium).
The term "pharmaceutically acceptable or under food law acceptable ester" as used herein, either alone or in combination with another substituent, means esters of the carboxylic acid in which any of the carboxyl functions of the molecule, is replaced by an alkoxycarbonyl function: in which the R moiety of the ester is selected from alkyl (e.g. methyl, ethyl, n-propyl, t- butyl, n-butyl); alkoxyalkyl (e.g. methoxymethyl); alkoxyacyl (e.g. acetoxymethyl); aralkyl (e.g. benzyl); aryloxyalkyl (e.g. phenoxymethyl); aryl (e.g. phenyl), optionally substituted with hal- ogen, Cl-4 alkyl or Cl-4 alkoxy. Other suitable prodrug esters can be found in Design of pro- drugs, Bundgaard, H. Ed. Elsevier (1985) incorporated herewith by reference. Such pharmaceutically acceptable or under food law acceptable esters are usually hydrolyzed in vivo when injected in a mammal and transformed into the acid form of the carboxylic acid.
As used herein, "a pharmaceutically acceptable or underfood law acceptable carrier medium" includes any and all solvents, diluents, other liquid vehicles, dispersion or suspension aids, surface active ingredients, preservatives, solid binders, lubricants, and the like, as suited to the particular dosage form desired. Remington's Pharmaceutical Sciences, Fifteenth Edition, E. W. Martin (Mack Publishing Co., Easton Pa. 1975) discloses various vehicles or carriers used in formulating pharmaceutical compositions and known techniques for the preparation thereof. Except insofar as any conventional carrier medium is incompatible with the compounds of the invention, (such as by producing any undesirable biological effect or otherwise interacting in a deleterious manner with any other component(s) of the pharmaceutical composition), its use is within the scope of the invention.

Each of the claims set out a particular embodiments of the invention.
In accordance with the purpose of the invention, as embodied and broadly described herein, the invention is broadly drawn to provide for an enteral or parenteral composition comprising 1) a carboxylic acid and 2) a chemical energy providing macronutrient or caloric organic compound of the group consisting of amino acid, peptide, protein, fatty acid, glycerol, glyceride, triglyceride, monosaccharide, disaccharide, oligosaccharide and polysaccharide or combination thereof for use in the treatment of the physical condition of patient with a disorder of the group consisting of sepsis, severe sepsis, severe sepsis with septic shock, critical illness myopathy and critical illness polyneuropathy.
Exemplary carboxylic acids are acetoacetic acid, lactic acid, propionic acid, 3- hydroxypropa- noic acid, malonic acid, hydroxypentanoic acid, butyric acid, β-methylbutyric acid, β-hydroxy β-methylbutyric acid, erythrose, threose, l,2-butanediol,l,3-butanediol, 2,3- butanediol, 1,4- butanediol, hydroxybutyric acid, 3-hydroxybutyric acid, L- -hydroxybutyric acid, Ο-β-hydroxy- butyric acid, DL- -hydroxybutyric acid or a pharmaceutically acceptable or under food law acceptable salt or a pharmaceutically acceptable or under food law acceptable ester thereof. In a preferred embodiment the carboxylic acid is selected from the group consisting of aceto- acetic acid, hydroxybutyric acid, 3-hydroxybutyric acid and L- -hydroxybutyric acid or a pharmaceutically acceptable or under food law acceptable salt or a pharmaceutically acceptable or under food law acceptable ester thereof.
I n a more particular embodiment the carboxylic acid is acetoacetic acid (also diacetic acid); the organic compound with the formula CH3COCH2COOH. It is the simplest beta-keto acid group, and like other members of this class it is unstable. The methyl and ethyl esters, which are quite stable, are produced on a large scale industrially as precursors to dyes. Acetoacetic acid is a weak acid. It is of biochemical importa nce in va rious anima ls, including humans, as one of the endogenous ketone bodies produced by the liver when it breaks down fatty acids into Acetyl-CoA and TCA cycle intermediates are depleted (particularly oxaloacetate, which is formed from pyruvate derived from glycolysis). It can be viewed as the product of joining two acetic acid molecules via a condensation reaction that ejects a water molecule in the process, although that is only one of the ways of forming the acetoacetate molecule. I n the human body, a large portion of acetoacetate is converted to beta-hydroxybutyrate, a rich energy source for the brain, which ca nnot run directly on fatty acids themselves due to their poor ability to cross the blood-brain barrier. I n the mammalia n body, a large portion of acetoacetate is converted to beta-hydroxybutyrate.
I n yet another particular embodiment the carboxylic acid is β-Hydroxybutyric acid, also known as 3-hydroxybutyric acid, an organic compound and a beta hydroxy acid with the formula CH3CH(OH)CH2C02H; its conjugate base is beta-hydroxybutyrate, also known as 3-hydroxy- butyrate. β-Hydroxybutyric acid is a chiral compound having two enantiomers, D-β- hydroxybutyric acid a nd L- -hydroxybutyric acid. Its oxidized and polymeric derivatives occur widely in nature.
I n one embodiment the enteral or parenteral composition is intended for use in the treatment for preventing or improving muscle weakness of patient with a disorder of the group consist- ing of sepsis, severe sepsis, severe sepsis with septic shock, critical illness myopathy and critical illness polyneuropathy. I n other embodiments the enteral or parenteral composition is intended for use in the treatment for preventing or improving muscle weakness, despite muscle wasting of a patient with a disorder of the group consisting of sepsis, severe sepsis, severe sepsis with septic shock, critical illness myopathy and critical illness polyneuropathy.
In yet another embodiment of the invention, the composition is used without causing or with- out aggravating a hepato-pancreato-biliary disorder. In a more particular embodiment the composition is used without causing or without aggravating fatty liver.
In other embodiment of the invention the enteral or parenteral composition further comprises a pharmaceutically acceptable or under food law acceptable carrier.
In one embodiment of the invention the enteral or parenteral composition has a total calorie content between 16 - 106% of the calculated caloric target for intensive care (ICU) patients.

In yet another particular embodiment, the composition has a calorie content of monosaccharide, disaccharide, oligosaccharide and/or polysaccharide between 200 to 800 kcal/l, yet more preferable between 300 to 800 kcal/l, yet more preferable 400 to 700 kcal/l and most preferable 500 to 600 kcal/l.
In yet another particular embodiment, the composition has a calorie content of fatty acid, glycerol, glyceride and/or triglyceride between 200 to 600 kcal/l, yet more preferable between 250 to 550 kcal/l, yet more preferable 300 to 500 kcal/l and most preferable 350 to 450 kcal/l.
In another embodiment the fatty acid, glycerol, glyceride and/or triglyceride provide between 20 to 80 %, yet more preferable 25 to 45 % and most preferable 30 to 40 % of the total calorie content of said composition. In certain embodiments the carboxylic acid or carboxylate thereof or pharmaceutically acceptable or under food law acceptable salt or a pharmaceutically acceptable or under food law acceptable ester thereof is administered to a patient at a daily dose of about 1.6 mmol/kg to 79.3 mmol/kg, preferably of about 1.6 mmol/kg to 31.7 mmol/kg, more preferably of about 3.2 mmol/kg and the additional chemical energy providing macronutrient or caloric organic compound is administered to a patient at a dose of 10- 100% of the calculated caloric target for ICU patients.
In more particular embodiments this administration is enteral or parenteral, once to several times for one day to several days and in 84% of the patients less than 14 days.
In certain embodiments the composition is used in a treatment of a patient with a BMI under 24.9, more particularly in a treatment of a normal weight patient with a BMI between 18.5 and 24.9 or in the treatment of an underweight patient with a BMI under 18.5.
In one aspect, the present invention provides a method for preventing and treating sepsis, severe sepsis, severe sepsis with septic shock, critical illness myopathy and critical illness pol- yneuropathy. The method comprises administering the enteric or parenteral composition comprising 1) a carboxylic acid and 2) a chemical energy providing macronutrient or caloric organic compound of the group consisting of amino acid, peptide, protein, fatty acid, glycerol, glyceride, triglyceride, monosaccharide, disaccharide, oligosaccharide and polysaccharide or combination thereof. The carboxylic acid can be selected from the group consisting of aceto- acetic acid, lactic acid, propionic acid, 3-hydroxypropanoic acid, malonic acid, hydroxypenta- noic acid, butyric acid, β-methylbutyric acid, β-hydroxy β- methylbutyric acid, erythrose, thre- ose, l,2-butanediol,l,3-butanediol, 2,3-butanediol, 1,4- butanediol, hydroxybutyric acid, 3- hydroxybutyric acid and

The caloric target can be calculated as the caloric need times the Corrected Ideal Body Weight. The formula for calculating Ideal Body Weight for a female patient is 45.5 + [0.91x (height in cm - 152.4)] and for a male patient 50 + [0.91 x (height in cm - 152.4)]. If BMI<18.5, the Corrected Ideal Body Weight is (Ideal Body Weight + Actual Body Weight)/2, if 27 > BMI > 18.5, the Corrected Ideal Body Weight is the Ideal Body Weight, if BMI > 27, the Corrected Ideal Body Weight is the Ideal Body Weight x 1.2. The caloric need for a female patient > 60 years is 24 kcal/kg/day, the caloric need for a male patient > 60 years is 30 kcal/kg/day, the caloric need for a female patient≤ 60 years is 30 kcal/kg/day, the caloric need for a male patient≤ 60 years it is 36 kcal/kg/day.

EXAMPLES
This invention can be further illustrated by the following examples of preferred embod thereof, although it will be understood that these examples are included merely for purposes of illustration and are not intended to limit the scope of the invention unless otherwise specifically indicated. Materials and Methods
Set-up of the animal model
Diet-induced obesity: Male, 12-week old C57BL/6J mice (Janvier SAS Chassal, France) received ad libitum standard chow (10% fat, E15745-04, ssniff, Soest, Germany), or ad libitum high-fat diet (45% fat, E15744-34, ssniff) for 12 weeks. Body weight was quantified weekly. Only a nimals placed on the high-fat diet that reached a body weight above 30 g but below 45 g (to avoid morbid obesity-associated metabolic alterations) within the 12 weeks of diet were included in the study. Tail blood glucose measurements indicated that all mice remained normoglycemic during the obesity-inducing diet (Accu-check, Roche, Basel, Switzerland). Mice experiment 1: At 24 weeks of age, lean and obese animals were randomly a llocated to "healthy control" (lean healthy mice (n=8) and obese healthy mice (n=9)) or to "CLP." CLP groups were randomly subdivided into a fasted-CLP or fed-CLP group. The CLP- induced septic critical illness model and nutritional protocols of the animals have previously been described in detail (Marques et al, 2013 Crit Care 17(5):R193). Total body, fat and fat-free mass were quantified with DEXA scans at the start (day -2) and at the end of the 5-day experiment. After 5 days of critical illness, a nimals were sacrificed by decapitation, vital organs were removed, snap frozen in liquid nitrogen and stored at -80°C, or preserved in paraformaldehyde. I n lean CLP animals, 9/15 fasted and 7/11 fed mice survived until day 5. I n obese CLP anima ls, 9/10 fasted and 10/18 fed mice survived until day 5.
Mice experiment 2: We examined muscle force ex vivo in lean and diet-induced obese CLP mice. The experimental setup was comparable to that of mice experiment 1. Mice were randomly allocated to "healthy control" or "CLP." As in experiment 1 we had observed that muscle wasting occurred irrespective of feeding, we now only compared parenterally fed with pair-fed lean (n=17) and obese (n=15) healthy mice. Until day 5, 15/18 lean and 15/18 obese CLP mice survived. After 5 days, animals were deeply anesthetized and the m. extensor digi- torum longus (EDL) was carefully dissected from both hind limbs for ex vivo muscle force measurements.
Mice body and tissue composition and mass
To control for potential illness- or resuscitation-related changes in fluid content, dry weight of isolated tissues was obtained by a freeze-drying process. Myofiber cross-sectional area (CSA) was quantified on digital microscopy images of hematoxylin and eosin stained paraffin sections with in-house designed algorithms. In addition, the presence of myofiber degeneration, necrosis and inflammation was histologically evaluated. Triglyceride content of tissues was determined with a commercial colorimetric assay (triglyceride quantification kit, Abeam, Cambridge, UK).
Mice circulating fatty acids, glycerol and ketone bodies
Serum concentrations of free fatty acids, glycerol and 3-hydroxybutyrate (3-HB) were deter- mined with commercially available assay kits (free fatty acid fluorometric assay kit, Cayman Chemical Company, Ann Arbor, Ml, USA; glycerol assay kit, Sigma-Aldrich, Saint Louis, MO, USA; EnzyChrom ketone body assay kit, BioAssay Systems, Hayward, CA, USA).
Mice tissue gene expression and protein expression analyses
Messenger RNA of skeletal muscle and liver was isolated and cDNA was quantified in realtime as previously described with commercial TaqMan® Assays (Applied Biosystems, Carlsbad, CA, USA). Data were normalized to ribosomal 18S (Rnl8s) gene expression and expressed as fold change of the mean of the controls. Microtubule-associated protein 1A/1B-Iight chain 3 (LC3)-I, LC3-II (Ab from Sigma-Aldrich) and p62 protein (Ab from Novus, Littleton, CO, USA) levels were quantified in m. gastrocnemius with Western blots. Data were expressed relative to the means of the controls. Commercial kits were used to measure proteasome (20S-pro- teasome activity assay, InnoZyme) and cathepsin B/L activities (Cathepsin L activity kit, Milli- pore, Merck KGaA, Darmstadt, Germany) in m. tibialis anterior homogenates.
Patient studies Myofiber CSA: In vivo skeletal muscle needle biopsies were obtained from the m. vastus lateralis of the m. quadriceps femoris of ICU patients on day 8±1 of ICU stay (Casaer M et al, 2011 NEJM 365(6):506-17; Hermans G et al, 2013 Lancet Respir Med l(8):621-9). As healthy references, in vivo m. vastus lateralis needle biopsies (n=20) were available from healthy individuals undergoing minor urological intervention or surgery for inguinal herniation. Healthy volunteers had comparable demographics as ICU patients. From 122 patients of whom myofiber CSA were available (Hermans et al, 2013 Lancet Respir Med l(8):621-9), we selected 51 lean patients (BMI≤25 kg/m2) and 51 overweight/obese patients (BMI >25 kg/m2), matched with use of propensity scores obtained by logistic regression (one-to-one nearest neighbor matching without replacement and with a caliper of 0.2). For this propensity score matching, the following baseline characteristics were used: gender, age, presence of malignancy, diabetes, APACHE II score on admission, and randomization. Next, we investigated postmortem m. rectus abdominis skeletal muscle biopsies, harvested immediately after death, from which myofiber CSA was available (Derde S et al, 2012Crit Care Med 40(l):79-89). From 148 available biopsies, 43 lean and 43 overweight/obese patients were propensity score matched similarly as the first set. As healthy references, in vivo m. rectus abdominis biopsies (n=ll) were available from non-critically ill individuals with comparable demographics.
Muscle weakness: In fully cooperative patients, who were still in the ICU on day 8±1, muscle strength was quantified with the MRC sum score (Hermans et al, 2013 Lancet Respir Med l(8):621-9). To correct for a possible bias by an effect of the randomized intervention on ICU stay, a random sample of patients discharged from the ICU was assessed in the regular hospital ward on post- randomization day 8±1. Clinically relevant weakness was diagnosed when the MRC sum score was lower than 48. Of the 352 patients that were tested on post-admis- sion-day 8±1, 139 lean and 139 overweight/obese patients were propensity score matched, similarly as the first sets. Of the 139 lean patients, 74 patients were tested on the regular hospital ward, 65 in the ICU. Of the 139 overweight/obese patients, 76 patients were tested on the ward, 63 in the ICU. Statistics Normally distributed data were compared with one-way analysis of variance (ANOVA) with post hoc Fisher's LSD test for multiple comparisons. Not-normally distributed data were analyzed with parametric tests after log- or (double) square root-transformation if this resulted in a normal distribution. Comparison of proportions was performed using Fisher's exact tests. Continuous non-normally distributed data were compared with non-parametric Mann- Whitney U tests. Two-sided p-values≤0.05 were considered statistically significant (Statview 5.0.1, JMP 8.0.1 and SPSS 22 were used). Data are presented as box plots with median, interquartile ranges and 10th and 90th percentiles or as bars with whiskers, representing means and standard error of the mean (SEM). ANOVA or Mann-Whitney p-values are presented in figure leg- ends. Post-hoc p-values <0.1 are plotted on the figures.
Study approval
All animals were treated according to the Principles of Laboratory Animal Care (U.S. National Society for Medical Research) and the Guide for Care and Use of Laboratory Animals (National Institutes of Health). The protocols for these animal studies had been approved by the Institutional Ethical Committee for Animal Experimentation (project number P051/2010 and P050/2015). The study protocol of the human studies had been approved by the Institutional Review Board of the KU Leuven (ML1820, ML2707, ML4190, ML1094). Written informed con- sent was obtained from the patients' closest family member and from healthy volunteers.
Example 1: Mice study - body composition
We hypothesized that during critical illness, fat mobilized from excess adipose tissue can pro- vide energy to vital organs more efficiently than exogenous macronutrients, and that this might prevent lean tissue wasting. We tested this hypothesis in a centrally-catheterized mouse model of cecal ligation and puncture (CLP)-induced septic critical illness and in a human study. In lean and premorbidly obese mice, the effect of 5 days of critical illness on body weight and composition, muscle wasting and weakness was compared, each with fasting and parenteral feeding. Additionally, in matched lean and overweight/obese critically ill patients, we compared markers of muscle wasting in muscle biopsies of two muscle groups (musculus (m.) vastus lateralis and m. rectus abdominis) as well as muscle strength, quantified by the Medical Research Council (M RC) sum score.
Prior to CLP, body weight was significantly higher in obese than in lea n mice (35.3±0.5 g vs. 29.4±0.6 g, p<0.0001). This was attributa ble to a higher fat mass in obese compared to lean mice (9.0±0.6 g vs. 4.7±0.2 g, p<0.0001), whereas fat-free mass was equal in obese and lean mice (23.5±0.4 g vs. 22.7±0.4 g, p=0.2).
After 5 days of CLP-induced critical illness, all animals lost a comparable amount of body weight, hence body weight remained higher in obese vs. lean CLP mice (Fig. la- b). Critical illness also resulted in loss of fat mass, but obese CLP mice lost more than double the amount of fat mass over 5 days of illness than lean CLP mice (Fig. lc-d). I n both lean and obese CLP mice, the loss of body weight and fat mass was unaffected by parenteral feeding (Fig. 1). Critical illness resulted in a loss of lean tissue in lean, but not in obese mice, as demonstrated by the reduction in dry weight of isolated m. tibialis anterior and m. soleus (Fig. 2a-b). This coincided with a reduced myofiber CSA of the m. tibialis anterior in the lean, but not in obese CLP mice (Fig. 2c). Consequently, mean muscle myofiber size was larger in obese CLP mice than lean CLP mice (Fig. 2c). Fasting during critical illness tended to further reduce the dry muscle weight (Fig. 2a-b), whereas the occurrence of smaller myofibers was present in both fed and fasted animals (Fig 2c). Example 2: Mice study - markers of skeletal muscle atrophy and autophagy
We investigated whether less activation of atrophy pathways could explain the observed preservation of muscle mass and muscle fiber size in obese CLP mice. Compared to lean healthy control mice, muscle protein content tended to be reduced in lean fed CLP mice (83.9±8.3 μg/mg vs. 55.1±10.1 μg/mg, p=0.06) and was reduced in lean fasted CLP mice (50.4±11.1 μg/mg, vs. lean hea lthy controls, p=0.01). In contrast, obese CLP mice preserved their muscle protein content (108.1±20.8 μg/mg vs. 76.1±14.8 μg/mg in fed CLP mice p=0.8, and 63.5±6.6 μg/mg in fasted CLP mice p=0.1). Gene expression of markers of the ubiquitin- proteasome system, Fbxo32 and Trim63, were upregulated in lean and obese CLP mice (Fig. 3a- b). Fasted lean CLP mice displayed a further increase in Fbxo32 and Trim63 expression (Fig. 3a- b). Activity of the proteolytic enzyme 20S-proteasome was unaffected by critical illness (Fig. 3c). I n contrast, cathepsin activity was increased in lean CLP mice, whereas this increase tended to be attenuated in obese CLP mice (Fig. 3d). Compared to lean and obese healthy control animals, fasting further increased the cathepsin activity both in lean and obese CLP mice (Fig. 3d).
Gene expression of Atg7 was elevated in both lean and obese CLP mice, but most pronounced in fasted lean CLP mice (Fig. 3e). I n contrast, Atg5 gene expression was only increased in fasted lean CLP mice (Fig. 3f). The LC3 protein ratio (LC3-I I/LC3-I), a marker of autophagosome formation, appeared unaffected after 5 days of critical illness (Fig. 3g). Protein levels of p62, used as a marker of insufficiently activated autophagy, were elevated in CLP mice, irrespective of obesity or whether the mice were fasted or received parenteral feeding (Fig. 3h).
To exclude the involvement of increased fibrosis or myostatin-associated hypertrophy in the preservation of muscle mass, we quantified gene expression of fibrogenic genes Collal and S100a4, m uscle growth inhibiting factor Mstn, a nd hypertrophy marker Igfl. These markers were largely unaffected by illness. However, fasted lean CLP mice demonstrated lower Collal and higher Mstn gene expression levels than healthy mice and fasted obese CLP mice. Histological ana lysis of the muscle in lean and obese CLP mice indicated similar signs of fibrosis (63% and 71% respectively, p=0.6) and fasciitis (11% and 6% respectively, p=0.8). Also structural abnormalities (58% and 65% respectively, p=0.6) and signs of necrosis (16% and 6% respectively, p=0.3) were equally observed in lean and obese CLP mice. Example 3: Mice study - ectopic triglyceride content
To determine whether an effect on lipid content might contribute to the preservation of muscle mass in obese CLP mice, muscle triglyceride content was quantified. Whereas healthy lean and obese mice had comparable muscle triglyceride contents, muscle triglyceride content was decreased in lean CLP mice, irrespective of nutritional intake (Fig. 4a). I n contrast, triglyc- eride content of the muscle was preserved in fed and fasted obese CLP mice (Fig 4a). Furthermore, muscle mass of m. tibialis anterior correlated significantly with muscle triglyceride content (R=0.498, p=0.0002).
Next, we investigated whether a comparable effect was present in the liver. Healthy lean and obese mice had comparable hepatic triglyceride contents (Fig. 4b), confirming the absence of potentially adverse features of a morbid obesity-associated liver steatosis. Liver triglyceride content was decreased in lean CLP mice, irrespective of nutritional intake, whereas it was preserved in fed and fasted obese CLP mice (Fig. 4b).
Example 4: Mice study - markers of fatty acid and glycerol metabolism
The observations of enha nced loss of fat mass (Fig. lb) and preservation of ectopic (muscle and liver) fat (Fig. 4) in obese CLP mice, suggest that during CLP-induced critical illness, more fat was mobilized from the adipose tissue of obese CLP mice. Therefore, we subsequently quantified circulating levels of fatty acids and glycerol and markers of hepatic uptake and metabolism of these substrates. Serum fatty acid concentration was not different from controls in lean CLP mice. I n contrast, in obese CLP mice, fatty acid serum concentration was decreased (obese healthy control mice 1384.4±221.3 μΜ vs. obese CLP mice 804.9±76.8 μΜ; p=0.007) (Fig. 5a). Hepatic gene expression of Cd36, a fatty acid transporter, was markedly increased in obese (healthy, fasted-CLP and fed-CLP) mice compared to lean (healthy, fasted- CLP and fed-CLP) mice (Fig. 5b). Hepatic gene expression of Acad 7, the first enzyme of β- oxidation, was comparable in lean, obese, healthy, and CLP mice (data not shown). However, hepatic gene expression of Hmgcs2, encoding for the mitochondrial enzyme that catalyzes the first step of ketogenesis, decreased in lean CLP animals (lean healthy control mice 1.0±0.1 vs. lean CLP mice 0.6±0.1; p=0.01), whereas its expression was una ltered in obese CLP mice (Fig.5c). Thus, obese CLP mice showed higher Hmgcs2 gene expression tha n lean CLP mice. This difference in gene expression coincided with higher serum ketone body (3-HB) concen- trations in obese CLP mice than in lean CLP mice (Fig. 5d).
Healthy lean mice had lower serum glycerol concentrations than healthy obese mice. Whereas circulating glycerol was not altered by critical illness in lean mice, glycerol serum concentrations in obese CLP mice were reduced after 5 days of critical illness (Fig. 6a). Gene expression of Aqp9, an aquaglyceroporin membrane channel that conducts glycerol into the liver, was unaltered (Fig. 6b). However, gene expression of Gk, encoding the rate-limiting enzyme in the hepatic conversion from glycerol to glucose, was higher in obese compared to lean mice (Fig. 6c). Overall, these parameters were not affected by the nutritional intake, neither in lean nor in obese CLP mice (Fig. 5 and 6). Example 5: Mice study - muscle strength and recovery from fatigue
After 5 days of critical illness, only the lean but not the obese mice lost m. EDL mass (Fig. 7a). Lean and obese healthy control mice had comparable twitch tensions (39.2±1.9 mN vs. 43.9±4.6 mN; p=0.5), tetanic tensions (213.3±9.5 mN vs. 203±15.4 mN; p=0.4) and fatigue recovery rates (42% vs. 38%; p=0.2) (Fig. 7). Peak twitch tension was unaltered in lean and obese CLP mice (data not shown). However, lean CLP mice demonstrated a lower peak tetanic tension and a lower recovery from fatigue than lean control mice, whereas obese CLP mice maintained peak tetanic tensions and the recovery from fatigue was comparable to obese healthy control mice (Fig. 7b-c). Compared to lean CLP mice, obese CLP mice tended to have higher peak tetanic tensions and displayed better recovery from fatigue (Fig. 7b-c).
Example 6: Patient study - muscle wasting and weakness
We next assessed whether attenuation of muscle wasting and muscle weakness was also present in obese/overweight versus lean prolonged critically ill patients. Myofiber CSA of the m. vastus lateralis was comparable in lean and overweight/obese healthy volunteers. However, myofibers were significantly smaller in lean prolonged critically ill patients than in healthy volunteers, as illustrated by a shift to the left in the histogram of myofiber size distribution (Fig. 8a). In contrast, overweight/obese critically ill patients maintained their myofiber size compared to healthy controls, which resulted in larger myofibers compared to lean critically ill patients (Fig. 8a). These findings were confirmed in a second set of postmortem m. rectus abdominis biopsies (Fig. 8b). Furthermore, fewer overweight/obese prolonged critically ill patients suffered from muscle weakness than lean prolonged critically ill patients (12% vs. 24%: p=0.004).
In examples 1 to 6 we demonstrated in mice and humans that being obese prior to becoming critically ill protected against muscle wasting and weakness. As compared with lean critically ill mice, obese mice showed better preservation of muscle mass and myofiber size, irrespective of whether they were fasted or received parenteral nutrition. Furthermore, obese CLP mice preserved their muscle strength. Obesity, but not nutrition during critical illness, attenuated the loss of lipids and myofibrillary proteins, and increased mobilization and metaboli- zation of fat from adipose tissue. In human muscle biopsies of overweight/obese prolonged critically ill patients, myofiber size appeared more preserved than in lean patients. Moreover, fewer overweight/obese patients suffered from muscle weakness than lean patients, assessed one week after admission to the ICU.
Critical illness is known to induce loss of muscle mass and the development of muscle weakness (Kress JP, Hall JB, 2014 NEJM, 370(17):1626-35). Although multiple mechanisms under- lying muscle wasting and weakness during critical illness have been identified, efficient therapies preventing critical illness-associated muscle wasting and weakness remain elusive. Therefore, the finding that obesity not only protected against lean tissue wasting but also against muscle weakness during critical illness is remarkable.
We observed increased markers of the ubiquitin-proteasome and the autophagy-lysosome pathway in muscle of critically ill mice. Obesity tended to attenuate increased cathepsin activity after 5 days of critical illness. Furthermore, whereas in lean critically ill mice, fasting induced a significant further increase in atrophy markers, this fasting response was absent in obese critically ill mice. In addition to the ubiquitin-proteasome pathway, also insufficiently activated autophagy can play a key role in muscle wasting and the development of muscle weakness (Hermans et al, 2013 Lancet Respir Med l(8):621-9). Insufficient autophagy activation is characterized by elevated p62 protein levels and an inadequate rise in LC3-II/LC3-I ratio. We observed p62 accumulation in the presence of an unaltered LC3-II/LC3-I ratio and increased expression of autophagy-related genes Atg5 and Atg7 in muscle of lean and obese CLP mice. Similarly to the findings for the ubiquitin- proteasome pathway, only lean but not obese critically ill animals displayed an additional upregulation in autophagy genes in response to fasting. Histological analysis indicated presence of muscle abnormalities (such as myocyte necrosis, fibrosis and fasciitis) in our mice model consistent with earlier human and rodent observations. However, the histological markers as well as gene expression of fibro- genesis and muscle hypertrophy markers were not affected by the presence of obesity during critical illness, suggesting that these pathways did not contribute to the preservation of muscle mass in obese critically ill mice. The maintenance of muscle proteins and stored ectopic (muscle and liver) triglycerides in obese CLP mice suggests that obese mice, in contrast to lean mice, may use other energy stores during critical illness. The observation that total body fat mass was more reduced during critical illness in obese compared to lean mice, concomitantly with the preservation of ectopic fat, indicates that more lipids were released from adipose tissue stores of obese CLP mice. Theoretically, sufficiently available circulating fatty acids and glycerol for energy consumption would reduce the need for utilization of energy substrates stored in vital organs, such as structural lipids and proteins. However, obese CLP mice did not display higher circulating fatty acids and free glycerol than lean CLP mice. Possibly, we missed a rise in circulating lipids on an earlier time point. On the other hand, obesity has been shown to influence the turnover rate of circulating fatty acids and glycerol, and thus increased me- tabolization of these substrates by the liver could have decreased their serum concentrations. In our mouse study we indeed observed such signs of an elevated fatty acid and glycerol turnover rate in all obese mice, unaffected by nutrition or illness. The increase in circulating ketone bodies in obese CLP mice further indicates enhanced fatty acid metabolism. Obese mice thus appear to have a different metabolic response to prolonged critical illness as compared with lean mice. Together, our findings may suggest that obese critically ill mice preferentially use fat from adipose tissue, while lean critically ill mice may utilize ectopically stored lipids and proteins. Possibly, the combination of mobilizing excess stored triglycerides in adipose tissue, and enhanced metabolism of fatty acids and glycerol from these stores, prevents or decreases the use of stored proteins and triglycerides in muscle tissue during critical illness. Glycerol and fatty acid metabolism can indeed generate vital energy through the production of glucose and ketone bodies. In addition, ketone bodies may also directly be involved in the attenuation of muscle wasting, comparable to what has been observed in pancreatic cancer cachexia (Shukla SK et al, 2014 Cancer&Metabolism 2:18).
It was demonstrated earlier that administration of parenteral nutrition to critically ill patients could not attenuate muscle wasting and even aggravated weakness (Hermans et a I, 2013 Lancet Respir Med l(8):621-9; Derde S et al, 2012Crit Care Med 40(l):79-89). Our observations now suggest that the use of endogenous lipids released from the adipose tissue may counteract muscle wasting.
Example 7: Mice study - effect of administration of D,L-3-hydroxybutyrate
The observation that in contrast to lean mice, obese mice strikingly do not suffer from muscle wasting and weakness when critically ill and they present with higher serum levels of the ketone body 3-hydroxybutyrate during illness, prompted us to assess whether the administra- tion of 3-hydroxybutyrate to lean critically ill mice could prevent muscle wasting and weak- ness. Within the skeletal muscle, 3-hydroxybutyrate has shown to be effectively used as energy source and was found to improve physical endurance in highly trained athletes. Also, there is evidence that ketone bodies could inhibit muscle atrophy. Therefore, we hypothesized that the administration of 3-hydroxybutyrate to lean critically ill mice could prevent muscle wasting and weakness.
We studied the effect of subcutaneous administration of D,L-3-hydroxybutyrate sodium salt on muscle wasting and weakness in a validated mouse model of prolonged critical illness evoked by sepsis (cecal ligation and puncture followed by resuscitation and intensive medical care). The intervention was studied in the parenterally fed and in the fasted state.
M uscle function was quantified in isolated extensor digitorum longus (EDL) muscle. Critical illness in parenterally fed mice (PN) reduced the absolute maximal force generated by EDL to 57% of healthy controls (p<0.0001) (Figure 9). However, when parenterally fed critically ill mice received subcutaneous twice daily a bolus of 75 mg of D,L-3- hydroxybutyrate sodium salt (PN+3HB), maximal muscle force improved dramatically to 83% of healthy controls (p<0.0001) (Figure 9). In contrast, in fasted critically ill mice, twice daily D,L- 3-hydroxybutyrate sodium salt boluses of 75 mg (fasting+3HB) increased risk of death (FigurelO) and in survivors reduced maximal muscle force to 33% of the force of healthy control mice (p<0.0001) (Figure 9).
M uscle wasting was evaluated by quantification of the dry weight of isolated skeletal muscles. M uscle weight of the EDL muscle decreased in all critically ill mice, irrespective of hydroxybutyrate treatment or nutritional regime (1.9 ± 0.3 mg for PN, 2.1 ± 0.3 mg for PN+3HB, a nd 2.0 ± 0.4 mg for fasting+3HB as compared with 2.7 ± 0.3 mg in healthy control mice; p<0.0001) (Figure 11A). Also the weight of the larger tibialis anterior muscle decreased significantly in all groups of critically ill mice as compared with healthy controls, again irrespective of hy- droxybutyrate treatment and feeding regime (9.0 ± 1.2 mg for PN, 8.9 ± 1.4 mg for PN+3H B, and 8.4 ± 1.8 mg for fasting+3H B versus 12.4 ± 1.3 mg in healthy controls; p<0.0001) (Figure 11B).
I n a second experiment we compared the effect of a lipid-rich, ketogenic diet (90% lipids, 10% glucose), with standard PN (35% lipids, 49% glucose, 16% proteins) on muscle wasting and weakness in our mouse model of prolonged critical illness evoked by sepsis. Critical illness in PN mice reduced the absolute maximal force generated by EDL to 58% of healthy controls (p<0.0001), whereas mice on a lipid-rich diet (Lipid) presented with highly improved maximal force to 73% of healthy controls (p=0.04) (Figure 12). M uscle dry weight of the EDL muscle decreased in all critically ill mice, irrespective of nutritional regime (2.9 ± 0.6 mg for PN, 2.9 ± 0.6 mg for Lipid, as compared with 4.3 ±1 mg for healthy controls; p<0.0001) (Figure 13A). Also tibialis anterior dry weight decreased similarly in all critically ill mice (9.6 ± mg for PN and 10.2 ± 1.8 mg for Lipid versus 12.7 ± 3.4 mg in healthy controls; p≤0.001) (Figure 13B). The lipid-rich diet increased circulating 3-hydroxybutyrate to 0.8 ± 0.6 mM (p<0.0001 compared to PN critically ill mice and healthy controls) (Figure 14). Adversely, livers of Lipid critically ill mice contained 7-times more triglycerides than PN critically ill mice and healthy con- trols (p<0.0001) (Figure 15). This unfavorable liver steatosis limits the therapeutic potential of a lipid-rich, ketogenic diet during critical illness.
I n conclusion, daily supplementation of D,L-3-hydroxybutyrate to parenterally fed mice largely prevented muscle weakness but not muscle wasting during prolonged sepsis- induced critical illness. A similar preventive effect on muscle weakness but not wasting was observed with the administration of a lipid-rich diet, but at the cost of unfavorable liver steatosis.
Example 8: Energy experiment
To investigate whether there is any potential synergy in the effect on muscle weakness of D,L- 3-hydroxybutyrate sodium salt (3HB) and the individual macronutrient components of stand- ard parenteral nutrition (lipids, proteins, glucose) we performed an additional animal experiment. We again used our validated mouse model of prolonged (5 days) critical illness evoked by sepsis (cecal ligation and puncture followed by fluid resuscitation and intensive medical care). Critically ill mice received twice daily a bolus injection of 75 mg of 3HB combined either with standard total parenteral nutrition (3HB+TPN, mixture of glucose, lipids and amino ac- ids), a glucose infusion (3HB+GLUC), a lipid-low-glucose infusion (3HB+LI P), or an amino-acids- low-glucose infusion (3HB+AA) [Table 1 for composition].
M uscle mass and function was quantified in isolated extensor digitorum longus (EDL) muscle. Total EDL muscle weight decreased similarly in all critically ill mice, irrespective of parenteral nutrition composition with which the 3HB was combined (Figure 16A). I n contrast, muscle force was affected differently among the ill groups (Figure 16B). Mice in the TPN+3HB group reached 76% (212±14mN) of the maximal muscle force of healthy controls (278±17mN, p<0.002), similarly to our previous findings. In contrast, the maximal force reached by the GLUC+3HB, LIPID+3HB and AA+3HB groups was significantly lower than the TPN+3HB group (p<0.05) with respectively 62% (173±13mN), 57% (158±16mN) and 56% (155±15mN) of the maximal muscle force of the healthy controls (p<0.0001). Specific maximal muscle force, cor- rected for the total EDL weight, was comparable between TPN+3HB and healthy controls, whereas it was lower than controls similarly in the GLUC+3HB, LIPID+3HB and AA+3HB groups (Figure 16C).
In conclusion, we could confirm that daily supplementation of D,L-3-hydroxybutyrate (3HB) to total parenteral nutrition largely prevented muscle weakness but not muscle wasting dur- ing prolonged sepsis-induced critical illness. Importantly, the improvement of muscle weakness with ketone supplementation was only observed when combined with total parenteral nutrition that comprised a balanced mixture of glucose, lipids and amino acids (Figure 16).
