[Treatment of arterial hypertension with captopril in lupus nephropathy]

Abstract

We present a non-controlled prospective study of 10 hypertensive patients with systemic erythematous lupus and nephropathy, treated with captopril exclusively or combined with other drugs, in order to assess its effectivity and potential side effects. Four of these 10 patients had mild hypertension; 3, moderate hypertension and 3, severe hypertension. In 5 of them, arterial pressures was controlled with just captopril; in other 3, we added furosemide and in one patient, we added furosemide and nifedipine. In one case, hypertension was not controlled. Renal function remained stable and proteinuria improved in six patients. Three patients presented reversible agranulocytosis, during or immediately after treatment. One of them was treated two years after with enalapril, without observing hematologic recurrence. We conclude that captopril is useful in treating arterial hypertension associated to lupous nephropathy, but frequent leukocyte counting controls must be done during the first months.
