Controversies in the pathogenesis of HIV-associated renal diseases

Abstract: The two most common HIV-associated renal diseases, HIV-associated nephropathy and HIVimmune-complex kidney disease, share the common pathologic finding of hyperplasia within the glomerulus. Podocyte injury is central to the pathogenesis of these diseases; however, the source of the proliferating glomerular epithelial cell remains a topic of debate. Parenchymal injury has been linked to direct infection of renal epithelial cells by HIV-1, although the mechanism of viral entry into this non-lymphoid compartment … Show more

“…In both crescentic glomerulonephritis and collapsing glomerulopathy, cells derived from PECs are now known to be major constituents of these extracapillary lesions, possibly representing an aberrant hyperplastic repair response by PECs. [3][4][5] We hypothesized earlier that patterns of aberrant repair in the proliferative podocytopathies lie on a spectrum of inflammatory injury, [32][33][34] recently identifying the TNF-a-TNFR2 axis as one possible causative pathway. 27,28 Intriguingly, TNF-a is one of a host of mitogenic activators of PKC, 26 inducing PKC phosphorylation of SSeCKS in PECs.…”

“…Poli et al (1993) descrevem, em alguns gatos, a presença de células do epitélio visceral proeminentes contendo gotículas de proteínas. Em humanos, a lesão hiperplásica no interior dos glomérulos, caracterizada como crescente ou pseudocrescente glomerular, é extremamente frequente nas duas doenças renais mais comuns associadas ao HIV, que são a glomerulopatia colapsante, conhecida como nefropatia associada ao HIV (HIVAN); e a glomerulonefrite imunomediada, conhecida como HIVICK (HIV immune-complex kidney disease) (Bruggeman & Nelson 2009). As crescentes glomerulares são comumente encontradas nas doenças glomerulares imunomediadas, incluindo a HIVICK, ao passo que as pseudocrescentes glomerulares são características na HIVAN (Bruggeman & Nelson 2009).…”

Originalmente, acreditava-se que as crescentes eram compostas por células parietais proliferadas, ao passo que as pseudocrescentes provavelmente se originavam de células epiteliais viscerais (podó-citos).…”
