          Abstract

          Interstitial nephritis is a common cause of renal dysfunction. It is primarily caused by drugs, infections, or autoimmune disorders. Patients with human immunodeficiency virus (HIV) infection can develop interstitial nephritis, although it typically occurs because of the aforementioned etiologies and not as a direct consequence of HIV infection. Interstitial lesions may occur in patients with HIV-associated nephropathy (HIVAN). However, interstitial nephritis without the glomerular injuries characteristic of HIVAN, and without the risk factors described earlier, is very rare. Here, we describe a rare case of interstitial nephritis that was likely caused directly by HIV infection and not by other etiologies.

          Nef harbors a major determinant of pathogenicity for an AIDS-like disease induced by HIV-1 in transgenic mice.

          Transgenic (Tg) mice expressing the complete coding sequences of HIV-1 in CD4+ T cells and in cells of the macrophage/dendritic lineages develop severe AIDS-like pathologies: failure to thrive/weight loss, diarrhea, wasting, premature death, thymus atrophy, loss of CD4+ T cells, interstitial pneumonitis, and tubulo-interstitial nephritis. The generation of Tg mice expressing selected HIV-1 gene(s) revealed that nef harbors a major disease determinant. The latency and progression (fast/slow) of the disease were strongly correlated with the levels of Tg expression. Nef-expressing Tg thymocytes were activated and alpha-CD3 hyperresponsive with respect to tyrosine phosphorylation of several substrates, including LAT and MAPK. The similarity of this mouse model to human AIDS, particularly pediatric AIDS, suggests that Nef may play a critical role in human AIDS, independently of its role in virus replication.

            The spectrum of renal histologies seen in HIV with outcomes, prognostic indicators and clinical correlations.

            Two hundred and twenty-one HIV-positive renal biopsies were analysed from Groote Schuur Hospital to determine outcomes and prognostic indicators based on histology and clinical features. The histology findings were compared with patient demographics, clinical and renal parameters, mortality, CD4 count and date of commencing combined anti-retroviral therapy (cART). Follow-up was between 1 and 3.5 years. We found a spectrum of renal histologies in HIV-positive patients of which HIV-associated nephropathy (HIVAN) was the most common histology. cART reduced the mortality in those with any feature of HIVAN by 57% [adjusted hazard ratio (AHR) 0.43, 95% confidence interval (CI) 0.22-0.85]. Of those patients with HIVAN who died, 79% died of renal failure as registered on their death certificate. Proteinuria and microcysts were shown to be poor prognostic indicators (AHR 1.36: 1.09-1.70 and 2.04: 1.24-3.37). In patients with HIVAN alone followed for up to 2 years on cART, estimated glomerular filtration rate remained stable and there was a trend towards decreased proteinuria. cART improved survival in patients with isolated immune complex disease. As mortality is improved in patients with any feature of HIVAN or isolated immune complex disease, cART should be initiated once any of these histological features are established. We believe the spectrum of disease that constitutes HIVAN needs to be more specifically defined. The ultimate outcome may be determined by the histological subtype.

              The spectrum of kidney disease in patients with AIDS in the era of antiretroviral therapy.

              With prolonged survival and aging of the HIV-infected population in the era of antiretroviral therapy, biopsy series have found a broad spectrum of HIV-related and co-morbid kidney disease in these patients. Our study describes the variety of renal pathology found in a prospective cohort of antiretroviral-experienced patients (the Manhattan HIV Brain Bank) who had consented to postmortem organ donation. Nearly one-third of 89 kidney tissue donors had chronic kidney disease, and evidence of some renal pathology was found in 75. The most common diagnoses were arterionephrosclerosis, HIV-associated nephropathy and glomerulonephritis. Other diagnoses included pyelonephritis, interstitial nephritis, diabetic nephropathy, fungal infection and amyloidosis. Excluding 2 instances of acute tubular necrosis, slightly over one-third of the cases would have been predicted using current diagnostic criteria for chronic kidney disease. Based on semi-quantitative analysis of stored specimens, pre-mortem microalbuminuria testing could have identified an additional 12 cases. Future studies are needed to evaluate the cost-effectiveness of more sensitive methods for defining chronic kidney disease, in order to identify HIV-infected patients with early kidney disease who may benefit from antiretroviral therapy and other interventions known to delay disease progression and prevent complications.
