Myeloma cast nephropathy is an obstructing disorder of renal tubules, caused by precipitation of Bence Jones proteins. Myeloma-like cast nephropathy (MLCN) has been reported in the literature to occur in various primary renal and nonrenal diseases. We present a series of three rare cases of cast nephropathy, two of which are HIV patients, and the third patient is receiving cisplatin-based chemotherapy. However, in all three patients plasma cell dyscrasia has been ruled out. A 30-year-old male was admitted to the hospital with facial cellulitis...

Human immunodeficiency virus (HIV) infection can cause a broad spectrum of renal diseases. However, there is paucity of Indian data on the patterns of renal lesions in HIV-seropositive patients. The aim of the present study was to delineate the spectrum of renal lesions in HIV/acquired immunodeficiency syndrome patients. In this prospective study, all HIV-positive patients of both genders aged >18 years were screened for renal disease. Patients with proteinuria of more than 1 g/24 h were subjected to renal biopsy...

Proliferation of glomerular epithelial cells, including podocytes, is a key histologic feature of crescentic glomerulonephritis. We previously found that retinoic acid (RA) inhibits proliferation and induces differentiation of podocytes by activating RA receptor-α (RARα) in a murine model of HIV-associated nephropathy. Here, we examined whether RA would similarly protect podocytes against nephrotoxic serum-induced crescentic glomerulonephritis and whether this effect was mediated by podocyte RARα. RA treatment markedly improved renal function and reduced the number of crescentic lesions in nephritic wild-type mice, while this protection was largely lost in mice with podocyte-specific ablation of Rara (Pod-Rara knockout)...

Mutations in MYH9 gene encoding the nonmuscle myosin heavy chain IIA (NMMHC-IIA) are related to a number of rare autosomal-dominant disorders which has been known as May-Hegglin disease, Sebastian syndrome, Fechtner syndrome and Epstein syndrome. Their common clinical features are congenital macrothrombocytopaenia and polymorphonuclear inclusion bodies, in addition to a variable risk of developing proteinuria, chronic kidney disease progressing toward end stage, sensorineural deafness and presenile cataracts...

Src family kinases (SFKs) belong to non-receptor protein tyrosine kinases (PTKs) and have been implicated in the regulation of numerous cellular processes, including cell proliferation, differentiation, migration and invasion, angiogenesis. The role and mechanisms of SFKs in tumorgenesis have been extensively investigated and some of SFK inhibitors are currently under clinical trials for tumor treatment. Recent studies have also demonstrated the importance of SFKs in regulating the development of various fibrosis related chronic diseases (e...

Crystalline nephropathy can occur following treatment with multiple therapeutic agents. We describe a human immunodeficiency virus (HIV)-infected patient treated for 2 years with combination antiretroviral therapy including atazanavir (ATV). Kidney biopsy revealed a crystalline nephropathy associated with diffuse chronic and granulomatous interstitial inflammation. Following the biopsy, treatment with ATV was discontinued and kidney function returned to pretreatment baseline levels. ATV, which has a well-established association with nephrolithiasis, is a rare but important cause of crystalline nephropathy...

Patients with HIV infection have a wide spectrum of renal diseases. Some are known to be the direct effect of the viral infection while others are renal diseases that also occur in uninfected populations. HIV associated nephropathy (HIVAN) is considered to be a subtype of primary focal and segmental glomerulosclerosis that is distinct in HIV infected patients. It is more frequent in the African-American population and associated with mutations of the apolipoprotein L1 (APOL1) gene. HIV associated immune complex kidney disease (HIVICD) encompasses a spectrum of HIV associated renal diseases characterized by the presence of immune complex deposition within glomeruli...

Well-recognized association between HIV 1 infection and collapsing glomerulopathy (CG) raises the possibility that intrarenal infection by other viruses may also contribute to the development of this lesion in native or post-transplant kidneys. There is evidence in literature about association of these lesions with cytomegalovirus, Epstein-Barr virus, hepatitis C virus, and parvovirus B19 infections. Here, we present a case report of post-transplant BK virus nephropathy in a male child who was found to have CG in subsequent biopsy 2 months later...

The risk of acute and chronic kidney disease remains higher in HIV-infected persons than in the general population, and kidney disease in HIV-infected persons is associated with poor outcomes, including increased mortality. HIV-associated nephropathy occurs less frequently in the era of antiretroviral therapy. HIV immune complex kidney disease is being diagnosed more frequently, but the term is currently used to refer to a heterogeneous group of kidney diseases. Comorbid chronic kidney disease poses a growing burden in HIV-infected persons due to an overrepresentation of risk factors such as black race, diabetes, hypertension, and coinfection with hepatitis C virus...

Despite the therapeutic success of tenofovir (TFV) for treatment of HIV-1 infection, numerous cases of nephrotoxicity have been reported. Mitochondrial toxicity has been purported as the major target of TFV-associated renal tubulopathy but the underlying molecular mechanism remains unclear. In this report, we use metabolomics and proteomics with HK-2 cells and animal models to dissect the molecular pathways underlying nephropathy caused by TFV and its more toxic analog, adefovir (ADV). Proteomic analysis shows that mitochondrial chaperone TRAP1 and mtDNA replicating protein SSBP1 were significantly down-regulated in TFV and ADV treated HK-2 cells compared with controls...

Homeodomain interacting protein kinase 2 (HIPK2) is a critical regulator of multiple profibrotic pathways, including that of TGF-β1/Smad3. Genetic ablation of HIPK2 was shown previously to significantly reduce renal fibrosis in the experimental unilateral ureteral obstruction model and Tg26 mice, a model of HIV-associated nephropathy. To develop specific pharmacologic inhibitors of HIPK2 for antifibrotic therapy, we designed and synthesized small molecule inhibitor compounds on the basis of the predicted structure of HIPK2...

Kidney disease represents an important health concern among HIV-infected individuals, with an estimated prevalence ranging between 2.4 and 17%. The widespread use of antiretroviral drugs has changed the epidemiology of kidney disease in the HIV positive population, drastically reducing the percentage of patients affected by HIV-associated nephropathy (HIVAN), a complication characterized by apoptosis and de-differentiation of renal epithelial cells and podocytes. However, impaired kidney function remains an important issue among HIV-infected patients because of their long-term exposure to antiretroviral drugs and the growing burden of traditional risk factors associated with chronic renal disease...

The native kidney is a reservoir for HIV-1 and a site of viral replication, similar to lymphoid tissue, gut-associated lymphoid tissue or semen. The ability of the virus to persist may result from either a true latency or sequestration in an anatomic site that is not effectively exposed to antiretroviral therapy. The presence of HIV in kidney epithelial cells will lead progressively to end-stage renal disease. For decades, HIV-infected patients were excluded from consideration for kidney transplantation. Hemodialysis and peritoneal dialysis were the only forms of treatment available to these patients...

HIV-associated nephropathy (HIVAN) is characterized by heavy proteinuria, rapidly progressive renal failure, and distinct morphological features in the kidney. HIV-induced epithelial-mesenchymal transition (EMT) is critically important for the progression of kidney injury. In this study, we tested the role of hedgehog pathway in the HIV-induced EMT and fibrosis of kidney. We used the Tg26 mice, the abundantly used HIVAN mouse model, to investigate the activation of hedgehog pathway by HIV. Western blotting and real time PCR results showed that renal tissue expression of hedgehog pathway related molecules, including hedgehog homologous (Shh, Ihh, Dhh), PTCH, and Gli1, were increased in HIVAN (Tg26) mice; while immunofluorescent staining displayed localization PTCH expression in podocytes...

Kidney diseases in human immunodeficiency virus (HIV)-infected patients are often misdiagnosed. Despite reductions in morbidity and mortality owing to widespread use of highly effective combination antiretroviral therapy (cART), acute kidney injury (AKI) and chronic kidney disease (CKD) are still more common in these patients than in the general population, and are associated with poor health outcomes. HIV-associated nephropathy and HIV immune complex kidney diseases are the more recognizable HIV-related kidney diseases...

Two coding sequence variants in the APOL1 gene (G1 and G2) explain much of the increased risk for FSGS, HIV-associated nephropathy, and hypertension-attributed ESRD among people of recent African ancestry. The ApoL1 protein is expressed in a wide variety of cell tissues. It has been assumed that the majority of circulating ApoL1 is produced by the liver, but this has not been shown. Using mass spectrometry, we genotyped and quantified the circulating ApoL1 in two liver transplant recipients whose native APOL1 genotype differed from the genotype of the deceased donors, allowing us to differentiate liver- from nonliver-produced ApoL1...

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...

HIV-1 transgenic mice on the FVB/NJ background (TgFVB) represent a validated model of HIV-associated nephropathy (HIVAN). A major susceptibility locus, HIVAN1, was previously mapped to chromosome 3A1-A3 in a cross between TgFVB and CAST/EiJ (CAST) strains, and introgression of a 51.9 Mb segment encompassing HIVAN1 from CAST into TgFVB resulted in accelerated development of nephropathy. We generated three sub-congenic strains carrying CAST alleles in the proximal or distal regions of the HIVAN1 locus (Sub-II, 3...
