Effects of Sodium Thiosulfate During Resuscitation From Trauma-and-Hemorrhage in Cystathionine-γ-Lyase Knockout Mice With Diabetes Type 1. Front Med (Lausanne) 2022; 9:878823. [PMID: 35572988 PMCID: PMC9106371 DOI: 10.3389/fmed.2022.878823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Accepted: 04/06/2022] [Indexed: 11/13/2022] Open
Abstract
Background Sodium thiosulfate (STS) is a recognized drug with antioxidant and H2S releasing properties. We recently showed that STS attenuated organ dysfunction and injury during resuscitation from trauma-and-hemorrhage in CSE-ko mice, confirming its previously described organ-protective and anti-inflammatory properties. The role of H2S in diabetes mellitus type 1 (DMT1) is controversial: genetic DMT1 impairs H2S biosynthesis, which has been referred to contribute to endothelial dysfunction and cardiomyopathy. In contrast, development and severity of hyperglycemia in streptozotocin(STZ)-induced DMT1 was attenuated in CSE-ko mice. Therefore, we tested the hypothesis whether STS would also exert organ-protective effects in CSE-ko mice with STZ-induced DMT1, similar to our findings in animals without underlying co-morbidity. Methods Under short-term anesthesia with sevoflurane and analgesia with buprenorphine CSE-ko mice underwent DMT1-induction by single STZ injection (100 μg⋅g-1). Seven days later, animals underwent blast wave-induced blunt chest trauma and surgical instrumentation followed by 1 h of hemorrhagic shock (MAP 35 ± 5 mmHg). Resuscitation comprised re-transfusion of shed blood, lung-protective mechanical ventilation, fluid resuscitation and continuous i.v. norepinephrine together with either i.v. STS (0.45 mg⋅g-1) or vehicle (n = 9 in each group). Lung mechanics, hemodynamics, gas exchange, acid-base status, stable isotope-based metabolism, and visceral organ function were assessed. Blood and organs were collected for analysis of cytokines, chemokines, and immunoblotting. Results Diabetes mellitus type 1 was associated with more severe circulatory shock when compared to our previous study using the same experimental design in CSE-ko mice without co-morbidity. STS did not exert any beneficial therapeutic effect. Most of the parameters measured of the inflammatory response nor the tissue expression of marker proteins of the stress response were affected either. Conclusion In contrast to our previous findings in CSE-ko mice without underlying co-morbidity, STS did not exert any beneficial therapeutic effect in mice with STZ-induced DMT1, possibly due to DMT1-related more severe circulatory shock. This result highlights the translational importance of both integrating standard ICU procedures and investigating underlying co-morbidity in animal models of shock research.

Abstract
Recent studies have revealed the impact of antibiotic-induced microbiome depletion (AIMD) on host glucose homeostasis. The kidney has a critical role in systemic glucose homeostasis; however, information regarding the association between AIMD and renal glucose metabolism remains limited. Hence, we aimed to determine the effects of AIMD on renal glucose metabolism by inducing gut microbiome depletion using an antibiotic cocktail (ABX) composed of ampicillin, vancomycin, and levofloxacin in mice. The results showed that bacterial 16s rRNA expression, luminal concentrations of short-chain fatty acids and bile acids, and plasma glucose levels were significantly lower in ABX-treated mice than in vehicle-treated mice. In addition, ABX treatment significantly reduced renal glucose and pyruvate levels. mRNA expression levels of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase in the renal cortex were significantly higher in ABX-treated mice than in vehicle-treated mice. We further examined the impact of AIMD on the altered metabolic status in mice after ischemia-induced kidney injury. After exposure to ischemia for 60 min, renal pyruvate concentrations were significantly lower in ABX-treated mice than in vehicle-treated mice. ABX treatment caused a more severe tubular injury after ischemia-reperfusion. Our findings confirm that AIMD is associated with decreased pyruvate levels in the kidney, which may have been caused by the activation of renal gluconeogenesis. Thus, we hypothesized that AIMD would increase the vulnerability of the kidney to ischemia-reperfusion injury.NEW & NOTEWORTHY This study aimed to determine the impact of antibiotic-induced microbiome depletion (AIMD) on renal glucose metabolism in mice. This is the first report confirming that AIMD is associated with decreased levels of pyruvate, a key intermediate in glucose metabolism, which may have been caused by activation of renal gluconeogenesis. We hypothesized that AIMD can increase the susceptibility of the kidney to ischemia-reperfusion injury.

Abstract
Introduction To assess changes in renal blood flow (RBF) in human and experimental sepsis, and to identify determinants of RBF. Method Using specific search terms we systematically interrogated two electronic reference libraries to identify experimental and human studies of sepsis and septic acute renal failure in which RBF was measured. In the retrieved studies, we assessed the influence of various factors on RBF during sepsis using statistical methods. Results We found no human studies in which RBF was measured with suitably accurate direct methods. Where it was measured in humans with sepsis, however, RBF was increased compared with normal. Of the 159 animal studies identified, 99 reported decreased RBF and 60 reported unchanged or increased RBF. The size of animal, technique of measurement, duration of measurement, method of induction of sepsis, and fluid administration had no effect on RBF. In contrast, on univariate analysis, state of consciousness of animals (P = 0.005), recovery after surgery (P < 0.001), haemodynamic pattern (hypodynamic or hyperdynamic state; P < 0.001) and cardiac output (P < 0.001) influenced RBF. However, multivariate analysis showed that only cardiac output remained an independent determinant of RBF (P < 0.001). Conclusion The impact of sepsis on RBF in humans is unknown. In experimental sepsis, RBF was reported to be decreased in two-thirds of studies (62 %) and unchanged or increased in one-third (38%). On univariate analysis, several factors not directly related to sepsis appear to influence RBF. However, multivariate analysis suggests that cardiac output has a dominant effect on RBF during sepsis, such that, in the presence of a decreased cardiac output, RBF is typically decreased, whereas in the presence of a preserved or increased cardiac output RBF is typically maintained or increased.

Abstract
BACKGROUND/AIMS The liver is regarded the most important source of glucose production and it is common practice to administer glucose during human liver transplantations to avoid hypoglycaemia. The purpose of this study was to evaluate the importance of extra-hepatic contribution (kidney, gut and muscle) to the glucose homeostasis in the anhepatic pig and in man during the anhepatic phase of human liver transplantations. METHODS Blood glucose and lactate were monitored in the anhepatic phase in 46 patients undergoing liver transplantation. Arterial-venous differences of lactate, glucose, glycerol, alanine and free fatty acids were measured over kidney, gut and hind leg in 18 pigs made anhepatic. RESULTS Blood glucose did not change significantly and blood lactate increased only marginally during the anhepatic phase of human orthotopic liver transplantation. In the anhepatic pig, however, blood glucose decreased with a halflife of about 26 min and blood lactate increased. Kidney gluconeogenesis was 0.116+/-0.016 mmol min(-1). Fifty percent of kidney glucose output could be accounted for by lactate- and glycerol uptake. CONCLUSIONS The results show that in humans extra hepatic gluconeogenesis is sufficient to maintain normal blood glucose in the anhepatic phase of orthotopic liver transplantation, while in the pig this was not the case.

Abstract
This review covers the recent advances that have been made in understanding the abnormalities of glucose metabolism found in critically ill patients. The alterations in the pathways of glucose production and utilization and the hormones and cytokines responsible for these are described. Therapies that have the potential to alter abnormal glucose metabolism and improve nutritional status are discussed.
