title: [Temporal evolution of renal involvement in a necropsy study of HIV patients from the pre and HAART eras].
abstract: BACKGROUND
  The aim of the present study is to analyze the impact of high activity antiretroviral therapy (HAART) on renal lesions observed in autopsies of HIV patients.
  
  
  METHODS
  Clinical records and renal pathologic samples from 100 HIV patients, who had died between 1984 and 2006, were reviewed, 61 before 1997 (group I) and 39 after. 24 of them had not received HAART (group II) and 15 had (group III). Premortem clinical and analytical data were obtained. Renal samples were stained with hematoxilin-eosin, PAS, Masson trichrome and silver-methenamine. The final pathologic diagnosis was recorded along with the findings at glomerular, tubular and interstitial levels. HIVAN was defined as the presence of focal or segmental glomerulosclerosis with glomerular collapse and microcystic tubulo -interstitial lesions.
  
  
  RESULTS
  The main causes of death were infections 68%, tumours 14%, and others 18%, especially liver diseases. Renal failure was present in 42% at the time of death. A predominance of tubular lesions exists in the three study groups, followed by interstitial lesions and glomerular lesions. The main diagnoses were acute tubular necrosis (ATN) and septic nephritis. Four cases of HIVAN were found. When the subjects who received HAART treatment were compared with those who did not, a significantly higher percentage of interstitial lesions in the group with HAART was observed. There were also more cases of acute tubular necrosis but these differences were not statistically significant.
  
  
  CONCLUSIONS
  Renal lesions were frequent in HIV patients independent of the presence or absence of HAART.
