Antineutrophil cytoplasmic antibody (ANCA) associated renal vasculitis and pregnancy. Report of one case

Abstract

ANCA mediated vasculitis mainly occur between the fourth and fifth decade of life; therefore, it is very uncommon to see pregnant patients with the disease. Vasculitis may affect significantly the course of pregnancy; in turn pregnancy can change the course of vasculitis. We report a 20 years old woman with AN-CA-mediated renal vasculitis lasting 10 years who consulted with a pregnancy of 15 weeks. She was in remission and had amenorrhea attributed to ovarian toxicity due to cyclophosphamide. Pregnancy had an uneventful course with spontaneous delivery at the 37th week, giving birth to a healthy newborn. Proteinuria increased during the course of pregnancy with a mild deterioration of kidney function. During the year after delivery, she had nephrotic proteinuria and a worsening of renal function.
