Hemolytic uremic syndrome (HUS) is an nonexceptional complication of infectious gastroenteritis. No one has already been reported in Senegalese publications. We made a retrospective study of the record of 7 patients with HUS among 256 cases of children with bloody diarrhea presenting to the pediatric unit of Aristide Le Dantec between august 1998 and july 1999. The mean age of the children was 33,14+/-25 months and the weight was -2,29 DS. The diagnosis is supported by the findings of an acute renal failure with urea at 1,28+/-0,51g/ l and creatinine at 41,46+/-25,48mg/l. An hemolytic anemia was constant, the blood film revealed schizocytes. We found a thrombocytemia only in two cases. A hight white blood cell count (more than 50000/mm3) was noted in for cases. Only one child made a good recovery. We insist on preventing gastroenteritis and aggressive and adapted management of the HUS.

Acute renal failure (ARF) is a significant cause of morbidity and mortality in children. It may be pre-renal, intrinsic, or post-renal (obstructive) in aetiology. ARF was investigated in children in the south-southern part of Nigeria to determine the prevalence, aetiology, management and outcome of ARF. A retrospective review of data from all children from birth to 16 years of age admitted into the Department of Paediatrics, University of Port Harcourt Teaching Hospital (UPTH), with the diagnosis of ARF over an 18 year period (January 1985 to December 2003) was performed. Information was obtained about the age, sex, clinical features, blood pressure, laboratory and radiological investigations, aetiology, and treatment received including dialysis. Information on the outcome, factors influencing outcome, and possible causes of death were reviewed. There were 211 patients, 138 (65.4%) males and 73 (34.6%) females (M:F, 1.9:1), with a hospital prevalence of 11.7 cases/year. The patients were aged 5 days to 16 years (mean 5.6+/-4.7 years). Oliguria was the most common clinical presentation in 184 (87.2%) patients. Hypertension was seen in only 39 (18.5%) patients. The causes were age-related. The neonates had ARF from severe birth asphyxia 27 (35.5%), septicaemia 17 (22.4%), with tetanus 4 (5.3%) and congenital malformations 11 (14.5%). Sixty-one (28.9%) and 29 (13.7%) patients had ARF from gastroenteritis and malaria respectively. The patients with leukaemia were all more than 10 years old and had acute lymphoblastic leukaemia. Two patients (1.9%) had Burkitts lymphoma involving the abdomen and 3 patients had HIVAN. 112 (53%) patients had anaemia with a mean haematocrit of 20.25+/-6.9%. Dialysis was indicated in 108 patients, but only 24 patients (22.2%) had peritoneal dialysis (PD), because of financial constraints and lack of dialysis equipment. Mortality rate was 40.5%. The causes of death were uraemia 60 (70.6%), overwhelming infection 5 (5.9%), and recurrent anaemia 20 (23.5%). Hypertension (X2 15.7, P<0.001) and lack of dialysis (X2 7.96, P<0.01) significantly affected outcome. Other factors associated with demise were delayed presentation (58.8%), use of herbal treatment (35%), and unaffordability of treatment (40%). ARF is a significant cause of mortality in Nigerian children. The patients are not adequately managed because of poverty and lack of facilities for dialysis. The causes of ARF in our environment are preventable, and should be expected.

Metformin-associated lactic acidosis (MALA) is a rare but serious clinical entity. It is almost always seen in patients with a serious underlying medical disorder, most often a degree of renal impairment or other factors that are known to predispose to the lactic acidosis. We report a case of MALA in which acute renal failure resulting from hypovolemia secondary to acute gastroenteritis likely precipitated the condition. Early recognition of this condition and initiation of treatment are important. Bicarbonate hemodialysis is the treatment of choice.

This case report describes a 56 year old patient with acute renal failure caused by a mushroom poisoning. Unspecific symptoms like a gastroenteritis followed by kidney insuffiency lead to the diagnosis of an orellanus syndrome. The toxin can be proved by thin layer chromatography in renal biopsy. Fast processing of hemoperfusion may avoid lasting kidney damage and dialysis.

From July 1998 to July 1999, 45 cases of acute renal failure were treated at Bir Hospital, Kathmandu. Out of which 24 were male and 21 were female. Age ranged from 11 months to 84 years with mean age being 35 years and 9 cases were below 10 years. Four cases with pre-renal azotaemia and twenty five cases of acute tubular necrosis (ATN) accounted for 64% of all cases. These were due to gastroenteritis 10, sepsis 6, post surgical 1, trauma 1 and obstretical complications 5. Multiple hornet stings were responsible for acute renal failure in 3 cases, acute urate nephropathy in 1 case and miscellaneous causes in 2 cases. Glomerulonephritis / vasculitis accounted for 17.7%, acute interstitial nephritis 4.4%, haemotytic uraemic syndrome (HUS) 6.6%, and post renal azotaemia in 6.6% of all cases. Mean serum creatinine was 8 mg/dl, mean blood urea 190 mg/dl. Eight cases were treated only conservatively, eighteen received haemodialysis, fourteen received peritoneal dialysis, three received both and two refused for dialysis. Average duration of hospital stay was 13.6 days. Out of the forty-five cases twenty-nine recovered normal renal function, ten expired, two recovered partially, two progressed to chronic renal failure and two left against medical advice. Overall mortality was 22.2%. Common causes of acute renal failure in our setting were gastroenteritis (22%) and sepsis (20%). HUS was exclusively seen in children following bacillary dysentery. Multiple hornet stings is an important cause of acute renal failure in our country.

Churg-Strauss syndrome (CSS) is a serious but rare pauci-immune vasculitis of small- and medium-sized blood vessels. It is commonly seen in association with bronchial asthma and/or allergic disorders. The syndrome is characterized by the presence of asthma, hypereosinophilia, and vasculitis in any part of the body. Vasculitis is often associated with significant distortion of normal functions. A rather severe case of CSS in an 8-year-old Nigerian girl with asthma and allergic rhinoconjunctivitis is reported. She presented with multiple morbidities, namely, vasculitic polyneuropathy and also nephritic-nephrotic syndrome that eventuated in acute renal failure after an onset of vasculitic gastroenteritis. Routine screening of all asthmatic patients for CSS is advocated.

Hemolytic uremic syndrome is caused primarily by Shiga toxin-producing Escherichia coli O157:H7. The most common cause of acute renal failure in children, hemolytic uremic syndrome also can occur in adults. Characteristic features of the syndrome are microangiopathic anemia, thrombotic thrombocytopenia, and renal failure. Although the presentation of this syndrome is diverse, the classic prodromal illness is bloody diarrhea following ingestion of hamburger meat contaminated with E. coli O157:H7, the most common mode of infection in the United States. Children with hemolytic uremic syndrome generally present with gastroenteritis complaints (e.g., abdominal pain or tenderness, nausea or vomiting, fever, anemia); affected adults may be asymptomatic. Complications from hemolytic uremic syndrome can include intussusception, chronic renal failure, and seizures in severe cases. Because an incubation period of approximately one week occurs between the start of diarrhea and the onset of hemolytic uremic syndrome, physicians should maintain a high index of suspicion; early laboratory testing is important to diagnose and manage this syndrome. Obtaining a complete blood count and stool culture and performing Shiga toxin testing are the first of a series of tests that may help diagnose hemolytic uremic syndrome.

Non-O1 Vibrio cholerae are gram-negative rods that can cause sporadic gastroenteritis, bacteraemia, and extraintestinal infections, primarily following the consumption of raw seafood or exposure of damaged skin to contaminated saltwater during the summer months. Bacteraemic necrotizing fasciitis caused by non-O1 V. cholerae has rarely been reported. Liver cirrhosis, haemochromatosis, and immunosuppression are important factors contributing to the severity of the infections and outcome. This report describes a case of liver cirrhosis in which right lower leg compartment syndrome and acute renal failure presented as the initial symptoms of bacteraemic necrotizing fasciitis. The organisms growing in the wound and blood cultures were identified as non-O1 V. cholerae. After antibiotic therapy, fasciotomy, right above-knee amputation, repeat debridement of the left lower leg and split-thickness skin grafts, the patient was eventually discharged in a stable condition.

In order to evaluate the effects of peritoneal dialysis as a modality of renal replacement therapy for adults with acute renal failure (ARF) of varied etiologies, we studied 43 ARF patients who underwent peritoneal dialysis at our hospital from April 2004 to November 2005. The age of the patients ranged from 18 to 75 years with a mean of 35 years. There was no significant difference in the incidence of ARF between males and females. Acute tubular necrosis secondary to acute gastroenteritis was the cause of ARF in 32 (80%) patients; four (10%) patients expired secondary to ARF. There was an average fall of around 60% in the S. creatinine at the end of PD. We did not notice any significant complications related to the procedure. We conclude that peritoneal dialysis is still a good option for the treatment of patients with ATN.

Diarrhea in children is often caused by enteropathogen infections that might benefit from early empirical antibiotic therapy. However, when the definition of the pathogen requires sophisticated laboratory studies, the etiology of enteritis is not known early in illness. Empirical therapy may be dangerous if the child is infected with a Shiga toxin-producing Escherichia coli (STEC) strain because antimicrobials may increase Shiga toxin (Stx) release, resulting in increased risk of microangiopathic hemolytic anemia with acute renal failure (hemolytic-uremic syndrome [HUS]) and death. There is a need for antimicrobials that would be effective against multiple bacterial enteropathogens yet not induce Stx release or increase the risk of HUS. Rifaximin has been evaluated in adults for treatment of bacterial enteritis and has a good record for safety and efficacy, but it has not been evaluated extensively in children with gastroenteritis. We therefore evaluated rifaximin's potential for phage induction, drug-induced bacteriolysis, and toxin release in 57 STEC strains (26 O157 and 31 non-O157 strains). Growth in ciprofloxacin, a known Stx phage inducer, caused bacteriolysis and release of toxin in 25/26 (96%) O157 strains and 15/31 (48%) non-O157 strains. In contrast, rifaximin did not induce phage replication or lysis in any strain. Toxin release in the presence of rifaximin was not different from release in the absence of antibiotic. Rifaximin, unlike many antibiotics used to treat pediatric gastroenteritis, does not induce phage-mediated bacteriolysis and Stx release.
