Spectrum of Secondary Glomerular Diseases in Adult Nephrotic Syndrome.

ABSTRACT

Background: In developing countries like India, thecauses for end stage renal failure has been changingwith glomerular diseases occupying an important place.The trend of various primary and secondary causes ofNephrotic Syndrome (NS) over the past few decadeshas been debatable especially with reference togeographical locations. Aim and Objectives: This studywas intended to find out the histologic patterns ofglomerular disease associated with NS in South Indiaand analyze the corresponding clinical and biochemicalabnormalities associated with these conditions.Material and Methods: One hundred eighty eightpatients in the age group of 18-80 years with NS whounderwent renal biopsy between the periodst thfrom1 January 2018 to 30 September 2019 wereincluded in this study. Baseline investigations and otherinvestigations related to renal profile evaluationincluding complement levels and HIV antibody weredone. Results: Focal Segmental Glomerulosclerosis(FSGS) accounted for the majority (25.5%) amongprimary glomerular diseases while among thesecondary glomerular diseases Lupus Nephritis (LN)(51.19%) constituted the majority and a substantialcontribution from Human Immunodeficiency VirusAssociated Nephropathy (HIVAN). LN was seen onlyin female patients with a mean age of 33.36 ± 10.74years. Among LN, Class III was the most predominantwhile Class IIIC was less frequent. C3 and C4complement levels were less than normal in Class IVand Class variants of LN. Conclusion: This studyhighlights the spectrum of Lupus Nephritis and HIVassociated nephropathy as a cause for adult NS in atertiary care center in South India
