Hepatitis B virus (HBV)-associated glomerulonephropathy (HBV-GN) has been increasingly re- ported, especially in adults. In the present study, the authors investigated the clinical and histopathology features of patients who suspected HBV-GN in 24 patients and age ranging from 23 to 74 years (mean 43 years). Asymptomatic hematuria was the most common presentation (54%); followed by edema and hyper- tension at equal percentages of 50%. The nephrotic syndrome was presented in 43%, the nephrito-nephrotic syndrome in 3.5%. Clinically suspected rapidly progressive GN was found in 14%. Renal insufficiency was determined in 30%. The most common pathologic finding was IgA nephropathy (IgAN 29%), followed by membranous nephropathy (21%), focal segmental glomerulo sclerosis (FSGS 11%), membranoproliferative GN (11%), post-infectious GN (11%). Liver disease activity also tended to be mild or had no symptoms of hepatitis. The authors remission rates both complete and partial were 75% (higher than the usual report), notwithstanding treatment. The authors achieved a sustained complete remission in half of the patients (3 in 6 cases) treated with steroid alone and 2 out of 7 cases (28.6%) treated with anti-viral therapy. Spontaneous remission was demonstrated in 2 (1 with IgAN + FSGS, and 1 with post infectious GN) out of 6 patients (33.3%). None of the patients in both treatment groups turned to ESRD that occurred in 2 cases receiving non- specific treatment. Of note, all of the patients who received anti-viral therapy or corticosteroid and had complete follow up were in remission either complete or partial.
