We review our 20-year experience of 636 children with nephrotic syndrome (NS) in Durban, South Africa; 306 (48.2%) were blacks, 307 (48.2%) Indians and 23 (3.6%) were a mixed group (coloured); 91 (14.3%) could not be categorised and were excluded from the analysis. In Indian children, 134 of 286 (46.8%) had biopsy-proven minimal change NS (MCNS) and 94.8% of these were steroid sensitive (SS); 60 (21%) had SSNS but without renal biopsy; 59 (20.6%) had focal segmental glomerulosclerosis (FSGS), with only 4.4% of these being SS. In blacks, membranous nephropathy accounted for 40% of cases; 86.2% were associated with hepatitis B virus antigens. Typical SSNS continues to be uncommon among blacks. Only 14.4% had either biopsy-proven SS-MCNS or SSNS; 32 had MCNS lesions on biopsy, but 18 were steroid resistant (SR); 67 of 236 (28.4%) had FSGS, all of whom were SR. Among coloured patients, 5 of 23 (21.7%) had biopsy-proven SS-MCNS and or unbiopsied SSNS; 10 (43.5%) had FSGS and 6 of 23 (26.1%) had membranous nephropathy. Proliferative lesions were present in only 2 of 23 (8.6%) coloured patients and was uncommon in all population groups. Overall mortality was 3.1%. In brief, this is the largest reported series of NS among children in Africa and shows a typical pattern in Indians, an unusual pattern of histological types in blacks and an intermediate picture in coloureds.

Background:Neonatal illness is a leading cause of death worldwide; sepsis is one of the main contributors. The etiologies of community-acquired neonatal bacteremia in developing countries have not been well characterized.Methods:Infants <2 months of age brought with illness to selected health facilities in Bangladesh, Bolivia, Ghana, India, Pakistan and South Africa were evaluated, and blood cultures taken if they were considered ill enough to be admitted to hospital. Organisms were isolated using standard culture techniques.Results:Eight thousand eight hundred and eighty-nine infants were recruited, including 3177 0–6 days of age and 5712 7–59 days of age; 10.7% (947/8889) had a blood culture performed. Of those requiring hospital management, 782 (54%) had blood cultures performed. Probable or definite pathogens were identified in 10.6% including 10.4% of newborns 0–6 days of age (44/424) and 10.9% of infants 7–59 days of age (39/358). Staphylococcus aureus was the most commonly isolated species (36/83, 43.4%) followed by various species of Gram-negative bacilli (39/83, 46.9%; Acinetobacter spp., Escherichia coli and Klebsiella spp. were the most common organisms). Resistance to second and third generation cephalosporins was present in more than half of isolates and 44% of the Gram-negative isolates were gentamicin-resistant. Mortality rates were similar in hospitalized infants with positive (5/71, 7.0%) and negative blood cultures (42/557, 7.5%).Conclusions:This large study of young infants aged 0–59 days demonstrated a broad array of Gram-positive and Gram-negative pathogens responsible for community-acquired bacteremia and substantial levels of antimicrobial resistance. The role of S. aureus as a pathogen is unclear and merits further investigation.

Every year, approximately 250,000 African women die during pregnancy, delivery, or the puerperium. Maternal mortality rates due to infectious diseases in Sub-Saharan Africa now supersede mortality from obstetric causes. Evidence is accumulating that tuberculosis associated with HIV/AIDS, malaria, sepsis, and other opportunistic infections are the main infectious causes of maternal deaths. Screening for these killer infections within prenatal healthcare programs is essential at this stage to prevent and treat causes of maternal mortality. The combination of proven effective interventions that avert the greatest number of maternal deaths should be prioritized and expanded to cover the greatest number of women at risk, and incorporated into a "prophylaxis and treatment community package of care." The effectiveness of these "packages of care" will need to be determined subsequently. Maternal deaths from tuberculosis are now on the increase in the UK, and due diligence and watchful surveillance are required in European prenatal services.

We report 81 of 107 cases of hemolytic uremic syndrome (HUS), admitted between July 1994 and February 1996, following an outbreak of Shigella dysenteriae type 1 dysentery in Kwazulu/Natal. All patients, excluding 1, were black with a mean age of 38 months (range 1-121); 50 (61.7%) were males. The mean duration of dysentery was 11.3 days (range 1-41) and HUS 15 days (range 1-91). Most patients had acute oliguric renal failure (90.1%), 42 (51.6%) required peritoneal dialysis. Complications included encephalopathy 30 (37.0%), convulsions 12 (14.8%) and hemiplegia 2 (2.3%), gastrointestinal perforation 8 (9.9%), protein losing enteropathy 26 (32.1%), toxic megacolon 4 (4.9%), rectal prolapse 5 (6.2%), hepatitis 11 (13.6%), myocarditis 5 (6.2%), congestive cardiac failure 3 (3.7%), cardiomyopathy 3 (3.7%), infective endocarditis 1 (1.2%), septicemia 15 (18.5%), disseminated intravascular coagulation 17 (21%). Leukemoid reactions were found in 74 (91.3%) patients, hyponatremia in 56 (69.1%), and hypoalbuminemia in 67 (82.7%). Stool culture for Shigella dysenteriae type I was positive in only 7 (8.6%) patients; Shiga toxin assays were not performed. Outcome was as follows: recovery 32 (39.5%), impaired renal function 8 (9.9%), chronic renal failure 26 (32.1%), end-stage renal disease 1 (1.2%), and death 14 (17.3%) patients.

This study, one of the largest series of children reported from Africa, demonstrates that nephrotic syndrome due to HIV-associated nephropathy (HIVAN) is the commonest presentation of HIV-related nephropathy in childhood. Highly active anti-retroviral therapy in combination with angiotensin-converting enzyme antagonists is highly effective in decreasing proteinuria and preserving renal function.
