title: [Two cases of heterozygous Fabry disease].
abstract: We report two cases of heterozygous Fabry disease with severe organ damage. Case 1 was a 47-year-old woman. In April 1977, at the age of 27 years, she had proteinuria and edema around the 26th week of her second pregnancy and was diagnosed as toxicosis of pregnancy. She had proteinuria after the delivery. In 1990, a renal biopsy showed zebra bodies under electron microscopic findings, and the patient was diagnosed as Fabry disease. In 1998, a myocardial biopsy showed identical findings. The patient developed severe hypertension and decreased renal function, and alpha-galactosidase enzyme replacement therapy was initiated. However, despite treatment, she was started on dialysis in 2004. Case 2 was a 40-year-old woman. In March 2003, the patient presented with severe hypertension. The patient had cerebral infarction, cardiac hypertrophy, old myocardial infarction and renal failure without diabetes mellitus, hyperlipidemia and collagen disease. The patient was diagnosed as Fabry disease from persistent numbness and pain in the four extremities, a family history of mortality due to heart disease, and skin biopsy findings. She is currently undergoing enzyme replacement therapy. It is generally known that female Fabry disease patients are asymptomatic or mildly symptomatic, as were the present two patients, but some can have marked organ disorders. Hence, even in female patients, it is necessary to consider Fabry disease as a causative disease of chronic renal failure.
