Clinicopathological Profile of Immunoglobulin A Nephropathy: A Study from Northeast India.

Immunoglobulin A (IgA) nephropathy is the most common primary glomerulopathy, with wide variation in its prevalence as well as clinical symptoms. Among the laboratory parameters, increased serum creatinine (SCr) levels, mean arterial pressure (MAP), and a decreased estimated glomerular filtration rate (eGFR) point toward poorer renal function. The Oxford 2016 scoring system for IgA nephropathy identified various histopathological variables, which serve as indicators of renal outcomes. There is a paucity of studies on the prevalence as well as the various clinical laboratory parameters correlating with the 2016 Oxford scoring system in northeastern India. The present study showed that IgA nephropathy was more common in the second and third decades, more prevalent in females, and mostly presented with edema. Nephrotic proteinuria, higher SCr, MAP, and decreased eGFR levels at presentation suggested poorer renal function in most subjects. The endocapillary hypercellularity, segmental sclerosis, tubular atrophy, and crescent variables of the 2016 Oxford scoring system showed a statistically significant relationship with various laboratory parameters at presentation.
