This descriptive and comparative review examines the changing epidemiology, treatment, renal and patient outcome of childhood nephrotic syndrome (NS) in tropical Africa (TpAfr). In the 1960s to 1980s, corticosteroid-resistant non-minimal change disease (nMCD) including quartan malaria nephropathy (QMN) was the dominant renal histopathology type. The overall incidence of NS was 0.35-1.34% of hospital admissions. Median age at onset of NS ranged between 4.0 and 12.0 years while the mean (SD) age range was 5.8 (3...

Human immunodeficiency virus (HIV) infection continues to be a leading cause of morbidity and mortality. HIV-infected individuals are now surviving for a relatively longer period and this is because of easy accessibility to antiretroviral therapy these days. As a result, chronic disease-related complications are now being recognized more often. Kidney disease in HIV-infected children can vary from glomerular to tubular-interstitial involvement. We searched the database to identify various kidney diseases seen in HIV-infected children...

Tubuloreticular inclusions (TRIs) are subcellular structures located within the cisternae of endoplasmic reticulum. Formation of TRIs has been linked to the exposure of excess interferon (IFN), either from endogenous or exogenous sources. In renal disease, TRIs have been most commonly associated with systemic lupus erythematosus (SLE), and human immunodeficiency virus-associated nephropathy (HIVAN). Case reports of patients with renal biopsies showing TRIs without underlying SLE or HIV are infrequent in adults, and to our knowledge none have been reported in children...

Studies have shown that podocytes and renal tubular epithelial cells from patients with HIV-associated nephropathy (HIVAN) express HIV-1 transcripts, suggesting that productive infection of renal epithelial cells precipitates development of HIVAN. However, podocytes and renal tubular epithelial cells do not express CD4 receptors, and it is unclear how these cells become productively infected in vivo We investigated the mechanisms underlying the infection by HIV-1 of podocytes cultured from the urine of children with HIVAN...

APOL1 renal risk alleles are associated with chronic kidney disease (CKD) in adults, with the strongest effect being for HIV-associated nephropathy. Their role in youth with perinatal HIV-1 infection (PHIV) has not been studied. In a nested case-control study of 451 PHIV participants in the Pediatric HIV/AIDS Cohort Study, we found a 3.5-fold increased odds of CKD in those carrying high-risk APOL1 genotypes using a recessive model [95% confidence interval (CI): 1.2 to 10.0]. We report an unadjusted incidence of 1...

Podocyte injury has a critical role in the pathogenesis of HIV-associated nephropathy (HIVAN). The HIV-1 transactivator of transcription (Tat), combined with fibroblast growth factor-2 (FGF-2), can induce the dedifferentiation and proliferation of cultured human podocytes. Cellular internalization of Tat requires interactions with heparan sulfate proteoglycans and cholesterol-enriched lipid rafts (LRs). However, the specific distribution of Tat in human podocytes and its ability to associate with LRs have not been documented...

Urticarial vasculitis (UV) is a subset of cutaneous vasculitis (CV), characterized clinically by urticarial skin lesions of more than 24 hours' duration and histologically by leukocytoclastic vasculitis. We assessed the frequency, clinical features, treatment, and outcome of a series of patients with UV. We conducted a retrospective study of patients with UV included in a large series of unselected patients with CV from a university hospital. Of 766 patients with CV, UV was diagnosed in 21 (2.7%; 9 male and 12 female patients; median age, 35 yr; range, 1-78 yr; interquartile range, 5-54 yr)...

Human immunodeficiency virus (HIV)-associated nephropathy (HIVAN) is most frequently seen as a late manifestation in adult patients with a high viral load and low T-helper cell (CD4) counts. We report a case of HIVAN in a black Zimbabwean teenager in whom the disease activity was well suppressed for years following highly active antiretroviral therapy (HAART). Proteinuria was absent at 9 years of age when he presented with vertically transmitted HIV infection. Within a few months of HAART, the viral load became undetectable and CD4 count was normalised...

Pediatric cryptococcosis has been documented in various organs, but pediatric renal cryptococcosis (RC) remains undocumented to date. The authors report RC in 2 children with AIDS, 7 and 9 years of age, with proteinuria. Both patients, on antiretroviral therapy (ARV) for 28 (patient 1) and 54 (patient 2) weeks each, had secured viral immunosuppression, but immune restoration was realized by patient 1 only. Cryptococcal immune reconstitution inflammatory syndrome (IRIS) was diagnosed on the renal biopsy from patient 1 based on the clinicopathological profile and the presence of segmental glomerular and an interstitial lymphoplasmacytic and granulomatous reaction to Cryptococcus neoformans, with a predominance of capsule-deficient fungal forms...

Human immunodeficiency virus (HIV)-infected children are at risk of developing several types of renal diseases, including HIV-associated nephropathy (HIVAN), which is usually seen during late stages of infection in children with a high viral load. This disease is defined by the presence of proteinuria associated with mesangial hyperplasia and/or global-focal segmental glomerulosclerosis combined with microcystic transformation of the renal tubules. Because HIVAN can have an insidious clinical onset, renal biopsy is the only definitive way of establishing a diagnosis...

Childhood human immunodeficiency virus-associated nephropathy (HIVAN) is defined by the presence of proteinuria associated with mesangial hyperplasia and/or global-focal segmental glomerulosclerosis, in combination with the microcystic transformation of renal tubules. This review discusses the pathogenesis of childhood HIVAN and explores how the current pathological paradigm for HIVAN in adults can be applied to children. The Human Immunodeficiency Virus-1 (HIV-1) induces renal epithelial injury in African American children with a genetic susceptibility to develop HIVAN...

Renal transplantation (Tx) is the treatment of choice for end-stage renal disease. The incidence of acute rejection after renal Tx has decreased because of improving early immunosuppression, but the risk of disease recurrence (DR) is becoming relatively high, with a greater prevalence in children than in adults, thereby increasing patient morbidity, graft loss (GL) and, sometimes, mortality rate. The current overall graft loss to DR is 7-8%, mainly due to primary glomerulonephritis (70-80%) and inherited metabolic diseases...

Human immunodeficiency virus (HIV) infection accounts for an unknown percentage of children with end-stage kidney disease (ESKD). Our objective was to compare the outcome of renal replacement therapy (RRT) in subjects with ESKD due to HIV and other diagnoses and to examine the prevalence of ESKD due to HIV. We analyzed Kt/V, morbidity, mortality, echocardiography, nutritional, and transplant status in 12 dialysis patients with HIV and 32 without HIV followed at our center between February 2002 and February 2007...

Human immunodeficiency virus-associated nephropathy (HIVAN) has rarely been reported in African children. In this single-center study, we analyzed ten children diagnosed with HIVAN from January 2000 to October 2006. There were eight boys and two girls, with a male:female ratio of 4:1. Their ages were from 5 months to 15 years (mean 6.8+/-6.2 years), with a peak age of 5-9 years. The presenting complaints included generalized edema (60%) and hypertension (50%). All patients had proteinuria on urine dipstick, with four (40%) at nephrotic range (proteinuria >or=500 mg/dl)...
