Plasmodium falciparum infection may be a cause of acute renal failure (ARF). Whereas renal failure appears to be a common complication of severe malaria in adults, it seldom occurs in children. The authors report a case of a previously healthy 9-year-old child, who was admitted with fever, vomits, diarrhoea, jaundice and obnubilation of consciencious. The results of laboratory tests performed confirmed the diagnosis of falciparum malaria. At the 2nd day of hospitalization she was in ARF and dialysis was necessary. We admitted that the probable underlying factors leading to this complication were: intravascular haemolysis, volume depletion, hypotension and hyperparasitaemia. Despite the presence of predictive factors of bad outcome the evolution was favourable with gradual recuperation of renal function.

Of 1857 Plasmodium falciparum malaria patients hospitalized from 1995 to 1998, 608 had severe malaria and 83 died. Acute renal failure, jaundice and respiratory distress were common in adults whereas children frequently had severe anaemia. Cerebral malaria occurred equally in adults and children but recovery from coma was quicker in children. Multiple complications caused high mortality in adults.

This study is of 25 cases of acute malaria encountered at autopsy. Cause of death was malaria in all the cases. The study covers a period of 6 years i.e. from January 1994 to December 1999. There was an upward trend in deaths due to malaria. P. falciparum malaria with its complications accounted for majority of deaths and cerebral malaria (CM) topped the list. Other complications observed were adult respiratory distress syndrome (ARDS), acute septicemic malaria, acute renal failure (ARF) and disseminated intravascular coagulation (DIC). The commonest presenting symptoms were fever with chills associated with central nervous system (CNS) complaints like altered sensorium and unconsciousness.

Falciparum malaria affect all ages with multiple-systemic complications which varies in different age group. We studied 242 children with complicated Falciparum malaria with a median age of 6.5 years to look for occurrence of different complications in younger and older age groups and overall mortality picture. Unarousable coma (40.5%), severe anemia (26.03%), repeated seizures (46.2%) and hepatopathy (32.2%) were commonest complications. Under five children had higher risk of development of cerebral malaria (P<0.01), severe anemia (P<0.05) and seizures (P<0.001); whereas above five children had higher risk of acute renal failure (P<0.05) and malarial hepatopathy (P<0.02). Over all mortality was 9.9%, cerebral malaria being the commonest cause (6.6%). Multi-system involvement was seen in 58.4% cases of death. Children having pulmonary edema, shock and cerebral malaria had high case fatality rate.

The influence of hyperbilirubinaemia on malaria-related mortality was explored among 1103 cases of acute, Plasmodium falciparum malaria at a referral hospital in Orissa, India. Most (64.3%) of the subjects investigated had > 1.2 mg bilirubin/dl serum and were therefore considered hyperbilirubinaemic. Compared with the other patients, those with hyperbilirubinaemia were much more likely to have cerebral malaria (24.1% v. 9.4%; P < 0.0001) or acute renal failure (9.5% v. 2.3%; P < 0.0001), but not severe anaemia (5.9% v. 4.3%; P < 0.22). Mortality was 7.9% among the patients with hyperbilirubinaemia (all the deaths being attributable to cerebral malaria, acute renal failure and/or severe anaemia) but only 1% among the non-hyperbilirubinaemics. There were no deaths, however, among the 506 hyperbilirubinaemics who did not have cerebral malaria, acute renal failure or severe anaemia, even among those with high serum concentrations of bilirubin. It therefore appears that, in acute, Plasmodium falciparum malaria, hyperbilirubinaemia is not in itself a severe complication, and only appears linked with mortality when associated with at least one other complication.

Renal failure remains a serious cause of mortality in Yemen. Our region has 1.25 million population and our hospital is the central hospital, which has a nephrology department and performs dialysis for the region. Between January 1998 and December 2002, we admitted 547 patients; including children, with acute renal failure (ARF) and chronic renal failure (CRF). CRF was observed in 400 patients, an incidence of 64 per million per year and a prevalence of 320 per million. ARF occurred in 147 persons with an incidence of 23.5 per million per year and a prevalence of 117.5 patients per million. Of all patients, 72% were adults (age range, 20-60 years) with a male preponderance. As a tropical country, malaria (27.9%), diarrhea (13.6%), and other infectious diseases were the main causes. Next most common were obstructive diseases causing CRF and ARF (26.8% and 12.9%, respectively), mainly urolithiasis, Schistosomiasis, and prostatic enlargement. However the cause of CRF in 57.5% of patients was unknown as most persons presented late with end-stage disease (64.7%), requiring immediate intervention. Other causes, such as hepatorenal syndrome, snake bite, diabetes mellitus, and hypertension, showed low occurrence rates. Patients presented to the hospital mostly in severe uremia and without a clear history of prior medications. The major findings were vomiting, acidosis, and hypertension with serum creatinine values ranging between 2.8-45 mg/dL (mean value, 13.4 mg/dL). Anemia was observed in 80.4% of CRF versus 62.6% of ARF patients. Hypertension prevalence was 65.5% among CRF patients, of whom 25% were in hypertensive crisis, whereas among ARF the prevalence was only 26.5%.

Between January 2000 and December 2001, renal involvement in 81 cases of malaria was studied. Their age ranged between 05 and 66 (mean 35.5) years. Distribution of malarial parasite was P falciparum (75), mixed infection (4) and P vivax (2). The evidence of clinical renal disease in the form of acute renal failure, electrolyte abnormality, abnormal urinary sediment and increased urinary protein excretion (>500 mg/24 hours) was found in 100%, 91.3%, 46.9% and 18.5% respectively. Probable aetiopathogenesis of acute renal failure (ARF) was multifactorial. Volume depletion (72.8%) was the dominant cause of ARF in these patients. In addition, hyperbilirubinaemia, intravascular haemolysis and sepsis were responsible for ARF in 64.2%, 70.3% and 25.9% cases respectively. All the patients were managed with anti-malarial drugs and dialysis support was needed in 35 patients (43.2%). Prognosis of malarial acute renal failure is favourable with mortality rate of 18.5%. Multi-organ failure was the commonest cause (33.3%) of death.

Malaria remains one of the world's major health problems, particularly in developing tropical countries. Imported malaria is reportedly increasing in Western countries. Acute renal failure (ARF) is the most common cause of death in severe malaria. We report the case of a 63-year-old female patient with a history of travel to a rural area in South Africa who was in coma and had a high fever on admission. Thirty percent of her erythrocytes were infected with Plasmodium falciparum. She had cerebral malaria, malarial nephropathy, anemia, hepatic dysfunction, and disseminated intravenous coagulation (DIC). Quinine and artesunate treatment decreased the number of parasites in the blood. To manage renal failure, hemodialysis was performed for 11 days. A relationship between ARF and hepatic dysfunction was suggested. This relationship is an indication of the clinical course of the disease. In this article, we discuss the mechanism underlying the development of malarial nephropathy and its management, particularly the usefulness of hemodialysis.

More than 340 parasitic species infect more than 3 billion people worldwide with varying morbidity and mortality. The Tropics constitute the main reservoir of infection with the highest clinical impact, owing to favorable ecological factors. Acquisition of infection, clinical severity, and outcome of a parasitic disease depend on innate and acquired host immunity as well as the parasite's own immune response against the host when infection is established. Organ transplant recipients may acquire significant parasitic disease in 3 ways: transmission with the graft, de novo infection, or activation of dormant infection as a consequence of immunosuppression. Malaria, Trypanosoma, Toxoplasma, and Leishmania are the principal parasites that may be transmitted with bone marrow, kidney, or liver homografts, and microsporidia with xenotransplants. De novo infection with malaria and kala-azar may occur in immunocompromised travelers visiting in endemic areas, while immunocompromised natives are subject to superinfection with different strains of endemic parasites, reinfection with schistosomiasis, or rarely, with primary infections such as acanthamoeba. The list of parasites that may be reactivated in the immunocompromised host includes giardiasis, balantidiasis, strongyloidiasis, capillariasis, malaria, Chagas' disease, and kalaazar. The broad clinical syndromes of parasitic infection in transplant recipients include prolonged pyrexia, lower gastrointestinal symptoms, bronchopneumonia, and meningoencephalitis. Specific syndromes include the hematologic manifestations of malaria, myocarditis in Chagas' disease, acute renal failure in malaria and leishmaniasis, and the typical skin lesions of Chagas' and cutaneous leishmaniasis. Many antiparasitic drugs have the potential for gastrointestinal, hepatic, renal, and hematologic toxicity, and may interact with the metabolism of immunosuppressive agents. It is recommended that transplant clinicians have a high index of suspicion of parasitic infections as an important transmission threat, as well as a potential cause of significant posttransplant morbidity.

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.
