Although the effects of angiotensin II receptor blockers (ARBs) on non-diabetic glomerulonephritis have been reported, studies of their effects on collagen-vascular diseases, particularly lupus nephritis, are limited. In this retrospective, observational study, systemic lupus erythematosus (SLE) patients (n = 7) with lupus nephritis and uncontrolled proteinuria were treated with an angiotensin-converting enzyme inhibitor followed by the ARB losartan (25 - 50 mg/day). Urinary protein excretion and renal function were evaluated. After 12 months of losartan, mean urinary protein excretion decreased significantly by 84.8%. Mean systolic and diastolic blood pressures also decreased significantly during the 12 months of losartan treatment, although not in normotensive patients. Complement 4, total complement activity and anti-dsDNA antibody levels, which are indices of SLE activity, and serum creatinine levels, which is an index of renal function, showed no change in response to losartan treatment. A more extensive evaluation of the effects of ARBs in patients with lupus nephritis and poorly controlled proteinuria is required.

Systemic lupus erythematosus is generally recognized to be a multisystem autoimmune disease with kidney involvement. However, the occurrence of other non-lupus glomerulopathies has been rarely reported in patients with systemic lupus erythematosus. It is well known that lupus nephritis may switch over time to another class according to the World Health Organization classification. It seems likely that IgA nephropathy is a clinical characteristic of a particular subset of patients with systemic lupus erythematosus. We report a 22-year-old Japanese man with recurrence of proteinuria. The renal flare occurred when he was without lupus clinical and serological activity, and renal remission was only obtained with angiotensin-converting enzyme inhibitor and angiotensin II receptor blocker therapy. Although the incidence of IgA nephropathy is high in Japan, we believe that this is the first report of a Japanese patient in which lupus nephritis switched over time to IgA nephropathy.
