Abstract
Needle biopsies of kidney were done in 35 cases of systemic lupus erythematosus (SLE) with renal lesions. The lupus nephritis were classified according to WHO classification and were correlated with response to therapy and prognosis. Detailed clinical features, routine haematological, biochemical tests (e.g., serum urea, creatinine, total protein and albumin, cholesterol, etc), examination of urine (degree of proteinuria and cells) and occurrence of various auto-antibodies e.g., antinuclear antibody (ANA), anti double stranded DNA (anti DsDNA) by enzyme immunoassay (EIA) method, LE cells and rheumatoid factor (RF) were studied in all cases. Clinically hypertension was present in 19 (54.3%) cases and nephrotic range of proteinuria was detected in 20 (57.2%) cases. ANA was found in 31 (88.5%) cases, anti DsDNA 24 (68.5%) and LE cells were detected in 25 (71.5%) cases. RF was detected in 2 (5.7%) cases. Histologically the most frequent lesions were class IV occurring in 15 cases (42.8%) with initial complete remission achieved only 4 cases by immunosuppressive therapy. Active lesions were also most frequent in this class. Class III lesions were found in 8 (22.8%) cases with 6 cases had complete remission. The best prognosis was noted in class II cases with 4 out of 5 (14.3%) cases had complete remission. Class V lesions were found in 6 (17.2%) cases with complete remission achieved in 3 cases. Only one patient presented with class VI lesion. RF positive cases had milder renal lesions.
