There is a paucity of data on the histopathological pattern of HIV-associated kidney diseases in most sub-Saharan African countries. This study was aimed at evaluating the histopathologic patterns of kidney diseases seen among HIV-infected treatment-naive patients in our center as this will allow for proper diagnosis and institution of appropriate treatment.Methods: In this cross-sectional study, consecutive patients who satisfied inclusion criteria and consented to participate were recruited. Percutaneous kidney biopsies were carried out as day procedures under real-time ultrasound guidance using an automatic spring-loaded biopsy gun as per our unit protocols. Baseline investigations including urea, creatinine, electrolytes, CD4 count, complete blood count, and glomerular filtration rate (eGFR) calculations, urinalysis and urine protein creatinine ratios were done on all the participants.Results: Fifty-five patients who satisfied the inclusion criteria were studied. The mean age of the study population was 38.34± 9.26 years, with 32% females. Mean serum creatinine was 249.6± 164.6 μmol/L, and mean CD4 count was 238 ± 210 cells/mL. The commonest histological type was FSGS seen in 20 patients (37.7%), followed by HIVAN seen in 17 (32.1%) patients; chronic interstitial nephritis in 7 patients (13.2%) and 6 (11%) had no significant pathological finding. Compared to non-HIVAN, HIVAN patients tended to have higher systolic BP (p= 0.05); higher serum creatinine levels (p= 0.05); lower eGFR (0.03) and higher urine protein to creatinine ratio [uPCR; p= 0.02].Conclusion: Kidney involvement is still a form of presentation among HIV-infected treatment-naïve patients and though a wide range of glomerular and tubulointerstitial lesions may be seen, FSGS and HIVAN are still the most common. We recommend assessment of kidney function, including urinalysis, as part of the routine evaluation of newly diagnosed HIV patients and biopsy where indicated to prognosticate and institute appropriate early treatment.Keywords: HIV, kidney disease, histologyhttps://www.dovepress.com/histopathological-pattern-of-kidney-diseases-among-hiv-infected-treatm-peer-reviewed-fulltext-article-IJNRDhivkidney diseasehistology |
