الوصف: | Abstract Background Muscle weakness is a frequently occurring complication of sepsis, associated with increased morbidity and mortality. Interestingly, obesity attenuates sepsis‐induced muscle wasting and weakness. As the adipokine leptin is strongly elevated in obesity and has been shown to affect muscle homeostasis in non‐septic conditions, we aimed to investigate whether leptin mediates the protective effect of obesity on sepsis‐induced muscle weakness. Methods In a mouse model of sepsis, we investigated the effects of genetic leptin inactivation in obese mice (leptin‐deficient obese mice vs. diet‐induced obese mice) and of leptin supplementation in lean mice (n = 110). We assessed impact on survival, body weight and composition, markers of muscle wasting and weakness, inflammation, and lipid metabolism. In human lean and overweight/obese intensive care unit (ICU) patients, we assessed markers of protein catabolism (n = 1388) and serum leptin (n = 150). Results Sepsis mortality was highest in leptin‐deficient obese mice (53% vs. 23% in diet‐induced obese mice and 37% in lean mice, P = 0.03). Irrespective of leptin, after 5 days of sepsis, lean mice lost double the amount of lean body mass than obese mice (P |
