OBJECTIVE: To evaluate the efficacy of pentoxifylline in the treatment of refractory nephrotic syndrome secondary to lupus nephritis. METHODS: We studied 11 patients who met the following inclusion criteria: (1) systemic lupus erythematosus (SLE) according to the American College of Rheumatology criteria; (2) lupus nephritis class III, IV, or V according to the World Health Organization; (3) proteinuria in the nephrotic range (> or = 3 g/24 h) for at least 6 months despite treatment. All patients received pentoxifylline 800-1600 mg/day. Clinical and laboratory data, including creatinine, urine test, creatinine clearance, and 24-h urinary protein, were collected monthly for 6 months. No changes in treatment were allowed, except for alterations in the dose of prednisone. RESULTS: All patients had received corticosteroids and immunosuppressants for at least 6 months. All patients showed a decrease in proteinuria concentrations after use of pentoxifylline from a median of 5.5 to 2.0 (p = 0.003). No patient discontinued the drug due to side effects. One patient had nausea and one had anxiety that disappeared after decreasing the dosage. CONCLUSION: Pentoxifylline seems to be effective in the treatment of refractory nephrotic syndrome secondary to lupus nephritis.
