Patients with diffuse proliferative lupus nephritis (DPLN) can have variable clinical course. Identification of the predictors of outcome would help to improve the management. We have studied the prognostic significance of clinical, laboratory and histological parameters in patients with DPLN.


Twenty nine patients diagnosed to be having DPLN seen between 1987 and 1991 were followed up for over 57 months. Parameters assessed for prognostic significance included serum creatinine, urine protein at the time of biopsy, blood pressure, type of immunosuppression, composite scores and individual components of activity index (AI) and chronicity index (CI). Kaplan-Meier survival curves were plotted and the results were compared using log rank test. Fishers' exact test was used to study the risk factors.


End stage renal failure developed in 7/29 (24.1%) patients; 7/19 (36.8%) who had hypertension and 7/16 (43.8%) who had nephrotic proteinuria developed renal failure, while none who had normal blood pressure or nonnephrotic proteinuria, developed renal failure (p < 0.01). Three patients had high activity index (> 12) and all three developed renal failure. Other parameters such as age, gender, serum creatinine, type of immunosuppression, CI and individual components of AI failed to predict the outcome (p > 0.05).


Hypertension, nephrotic proteinuria and high AI were predictive of progression to end stage renal failure in patients with diffuse proliferative lupus nephritis.
