Background: Cholera is a life-threatening secretory diarrheal disease caused by Vibrio cholera bacterium. On the contrary, local and specific use of cholera toxin (CT) at a low concentration can cause controlled fluid secretion. In the study, we explored the secretory action of CT in the intestine of rats with acute renal failure (ARF). Methods: Closed intestinal loop experiments were performed in ARF rats treated with CT. Secreted fluid and serum were analyzed for various ¬solutes and electrolytes. The presence of K+, Na+, Cl-, urea and creatinine were monitored. Histopathology analysis was carried out to evaluate the effect of CT in liver, kidney, and intestinal tissues. Results: A reduction in the absorption of water and electrolytes was observed over time and a secretory response started to appear within hours of CT treatment. The fluid secretory response with entrapped electrolytes was profound in ARF rats. Histopathological analysis of CT exposed tissues revealed that apart from the tissue damage produced by acute renal failure, no CT induced cellular changes occurred. Conclusion: CT can be used as a secretagogue to induce fluid and electrolyte secretion in ARF rats. However, effective measures should be taken to avoid CT induced acidosis.

Rhabdomyolysis is an acute life-threatening condition that can occur in childhood secondary to many causes. The authors report the case of a 3-year-old male child who presented with acute rhabdomyolysis. The peak plasma creatine kinase level was extremely high. The 2 main causes of rhabdomyolysis in childhood are viral myositis and trauma, which can sometimes lead to acute renal failure. The highest creatine kinase levels reported in the literature so far was a 6-digit level in 2014 case report. In this study, the authors report the case of a 7-digit creatine kinase level in a child secondary to viral myositis who did not require renal dialysis.

Rhabdomyolysis is a serious and life-threatening condition in which skeletal muscle is damaged, commonly resulting in acute renal failure. The causes of this clinical entity can be traumatic and non-traumatic. In the latter group, alcohol is the commonest cause. This report describes the case of a 25 year old man who presented with rhabdomyolysis leading to acute renal failure after an alcohol binge. He presented with painful legs and lower extremity compartment syndrome. The patient recovered with surgical fasciotomy and renal support. This case illustrates the importance of early recognition and treatment of alcohol related non-traumatic rhabdomyolysis and compartment syndrome.

The effects of several weak acids on the secretory actions of cholera toxin and the heat-stable enterotoxin of Escherichia coli (ST) have been examined in ligated jejunal loops in weanling pigs. Ascorbic and acetic acids had no effect, but L-lactic acid reduced the net fluid secretion caused by cholera toxin. Glutaric acid and p-aminobenzoic acid blocked net fluid secretion caused by cholera toxin or by ST. Antisecretory effects were pH dependent for p-aminobenzoic acid in this study and for nicotinic acid in a previous report (6). At a pH of 5.0, p-aminobenzoic acid treatment increased lumen-to-blood sodium flux and decreased the blood-to-lumen sodium flux caused by cholera toxin. These weak acid effects were more marked on fluid fluxes in enterotoxin-treated loops than in control loops and persisted for 20–30 min after acid removal from loops. These findings are discussed in terms of requirements for antisecretory activity and possible modes of action of antisecretory compounds.

Background : Acute Renal Failure (ARF) is a life threatening condition causing significant morbidity and mortality in children. Many studies on adult ARF survivors showed that renal insufficiency persisted after an attack of ARF. Children may be more susceptible to this injury due to immaturity and ongoing growth of the kidney.Objective : This study was conducted to assess the renal functional reserve or detect any sign of renal injury in children after an episode of Acute Renal FailureMethods : This prospective study was carried out in the Renal and Dialysis unit, Dhaka Shishu Hospital in 2007, January . Thirty patients were enrolled in this study by searching data held in the study centre.Results : Thirty (30) patients were selected in this study. Among them 46.7% was in the group > 5-10 years, only 10.0% was in age group < 1 year and more than 10 years respectively. Male were 63.3%, female were 36.7%.Causes of acute renal failure were diarrhoea with dehydration 43.3%, septicaemia 20.0%, Haemolytic Uraemic Syndrome (HUS) 20%, Acute Glomerulo Nephrities (AGN) 10.0%, Henoch Schonlein Purpura ( HSP) 3.3% and hepato renal syndrome 3.3%. During follow up Glomerular Filtration Rate(GFR) of the patients were in stage 1 in 76.7% cases , 10.0% in stage 2, 6.7% in stage 3 stage and in stage 4 & 5 3.3% cases.23.3% patients were found with GFR between stage 2 to stage 5, who had ARF due to HUS and HSP. The incidence of hypertension and proteinuria was found in 13.3% cases of HUS.Conclusion : The progressive nature of acute renal failure which may cause chronic kidney disease is an important observation.Northern International Medical College Journal Vol.6(1) 2014: 15-17

Abstract Despite glucose-6-phosphate dehydrogenase (G6PD) deficiency prevalence of 5% in the Amazon, primaquine is administered without G6PD screening. This is an important cause of hospitalization among Plasmodium vivax–infected individuals, leading to life-threatening anemia and acute renal failure across endemic areas. In Manaus, the frequency of primaquine-induced hemolysis was 85.2 cases per 100 000 primaquine users.

Rhabdomyolysis is caused by extensive damage to skeletal muscles resulting in elevated creatine phosphokinase (CPK), Lactate dehydrogenase (LDH), and aspartate aminotransferase (AST), leading to life-threatening consequences like acute renal failure, cardiac arrhythmias, and hyperthermia. A variety of causes for muscle damage are known, and one of the most common is drug-induced. Statins and many other agents are known to induce muscle damage, but here we report Entresto™ (Sacubitril/Valsartan) induced rhabdomyolysis which has not been previously reported as solely responsible in the literature.

Spinal surgery–associated rhabdomyolysis, although rare, is a life-threatening condition. Presented here is the case of a middle-aged, overweight man who underwent posterior lumbar surgery because of pain and neurogenic claudication. His postoperative course was complicated by the occurrence of rhabdomyolysis. Despite adequate treatment, acute renal failure developed as a sequela. His condition was grave enough to require the administration of intermittent hemodialysis. After a prolonged hospitalization and 5 sessions of hemodialysis, the patient achieved a full recovery. In view of the fact that rhabdomyolysis-induced acute renal failure is associated with a mortality rate of 20–50%, the outcome was favorable.

Acute diarrhea is usually mild and self-limited in normally healthy individuals. Further diagnostic evaluation is indicated in patients with severe diarrhea. We present a case of a 46-year-old woman who presented with dehydration and acute renal failure due to acute severe diarrhea. Initial stool study was suggestive ofAeromonas. Further stool test revealed offending bacteria, which led to appropriate antibiotic use. This paper emphasizes the importance of complete history and correlation between clinical data and laboratory tests.

The role of stem cell factor (SCF) and its receptor (c-kit) in the intestinal secretory response to cholera toxin (CT) was investigated using a ligated intestinal loop model in mice having mutations in the dominant white spotting (W) locus and the steel (Sl) locus. W/Wv mice, which express an aberrant form of the c-kit protein, failed to give an intestinal secretory response after luminal CT challenge. In contrast, W/Wv mice and their control littermates had equivalent intestinal secretory responses to Escherichia coli heat-stable enterotoxin (STa). Sl/Sld mice, which express only a soluble truncated form of SCF, also gave a significantly reduced intestinal secretory response to CT when compared to the secretory response of their littermate controls. The unresponsiveness of W/Wv mice to CT was restricted to the intestinal tract since these mice had foot pad swelling responses to CT challenge that were equivalent to their littermate controls. Restoration of mast cells in W/Wv mice by bone marrow transplantation of control littermate bone marrow did not reverse the CT-unresponsiveness of the intestinal tract. Histological evaluation of the gastrointestinal tract from W/Wv mice showed a normal distribution of enterochromaffin cells (ECC). CT challenge of either ligated intestinal loops from C57B1/6 mice or a mouse intestinal epithelial cell line (MODE-K) resulted in elevated levels of mRNA for SCF. MODE-K cells exposed to CT also had enhanced expression of c-kit. Finally, fluid obtained from CT-challenged ligated intestinal loops from C57B1/6 mice contained significant levels of SCF. Taken together, the above results suggest that CT-induced intestinal secretory responses are dependent upon SCF-c-kit interactions. These interactions appear to be induced as a consequence of CT stimulation of the intestinal tract and may also play a role in the development or functionality of the enteric nervous system.

1 Diquat (1,1'-ethylene-2,2'-bipyridilium) is a non-selective desiccant herbicide which, when administered orally to mammalian species, causes significant secretion of fluid into the lumen of the gastrointestinal tract. In order to characterize this secretory response in more detail the effect of sublethal doses of diquat dibromide (DQBr2) on intestinal secretion was investigated in vivo in the jejunum of anaesthetized rats. 2 Ligated segments of jejunum (10 cm) which were prepared in groups of up to five animals were filled with 500 μl of isosmotic DQBr2 solutions with concentrations ranging from 1-100 mM and maintained in the anaesthetized rat for 1, 2 or 3 h; in control experiments a solution of 100 mM NaBr was used. 3 It was found that while all of the fluid instilled into the segments was absorbed in the control experiments, there was both a dose- and time-dependent secretory response to DQBr2. Maximal fluid secretion occurred after treatment with 50 mM DQBr2 for 3 h. 4 Histological assessment of the jejunum revealed an increase in cell exfoliation and evidence of luminal distension after incubation with DQBr2. However, no structural damage to the mucosa could be seen to account for the fluid secretion. 5 The model described provides a quantitative means of evaluating intestinal secretion and may be used for elucidating the mechanism by which diquat alters fluid transport processes.
