Abstract
Introduction
Lupus nephritis (LN) is an immune complex glomerulonephritis, which is a very serious complication of systemic lupus erythematosus (SLE) as it can progress to end-stage kidney disease (ESKD).
Methods
In this study of 92 renal biopsy-proven LN, the patients were followed up for a minimum period of 2 years with a mean follow-up period of 5.4 ± 3.4 years.
Results
The mean serum creatinine of our study population was 1.4 ± 1.53. Our study population included 2 patients with class I lesions, 5 with class II, 22 with Class III, 53 with Class IV, and 10 with Class V lesions. Our therapeutic approach included only oral steroids for class I and class II lesions; for class III, IV, and V lesions, our approach included pulse steroids followed by oral steroids with either intravenous (IV) monthly cyclophosphamide (CYC) or mycophenolate mofetil (MMF). For maintenance, azathioprine or MMF were used along with low-dose oral steroids after 6 months of CYC or MMF. In CYC induction group containing 78 patients (84.7%), 66 patients (84.6%) attained remission (CR + PR), relapse in five patients (6.4%), ESRD on HD in five patients (6.4%), and death in two patients (2.6%).
Conclusion
At the end of the study, in all groups, 79 patients (85.86%) were in remission (CR + PR), six patients (6.5%) were in relapse, five patients (5.4%) had reached the ESKD stage on HD, and two patients (2.2%) died.
