We describe a patient with rheumatoid arthritis (RA) who developed a nephrotic syndrome during treatment with a fully human recombinant monoclonal antibody against TNFalpha (adalimumab, Humira, Abbott). The proteinuria disappeared spontaneously after cessation of anti-TNFalpha treatment and relapsed after rechallenge, pointing to anti-TNFalpha as the culprit. Although renal biopsy disclosed a membranous glomerulopathy, the clinical picture was more compatible with minimal lesion glomerulopathy. The pathogenesis of this side effect is not clear; several mechanisms could in theory lead to these abnormalities.

Tumor necrosis factor (TNF) inhibitors are widely used for the treatment of various rheumatic diseases. These agents may lead to development of systemic autoimmune diseases and renal complications. We report a patient with psoriatic arthritis and renal failure treated with two TNF inhibitors (Etanercept and then Adalimumab). After this treatment he developed proteinuria with nephrotic syndrome. A renal biopsy was performed highlighting GN with mesangial IgA deposits. Then he developed p-ANCA positivity. Following that, etanercept and adalimumab were stopped and a treatment by corticosteroids was initiated, but renal function decreased. Currently the patient is treated by haemodialysis. In our patient, the pathogenic role for anti-TNF therapy is suggested by the close temporal relationship with development of glomerular disease and by the improvement in proteinuria after drug withdrawal. However, the patient was treated once more with TNF agents, so he developed end stage renal disease.
