Abstract

Fanconi anaemia (FA) is a rare genetic disorder that predisposes to the development of aplastic anaemia and neoplasia. The pathophysiologic hallmark of FA is increased susceptibility to chromosomal breakage. Superoxide metabolism has also been shown to be involved in the cellular pathophysiology of FA. Human SOD (rh-SOD), an enzyme which dismutates superoxide, has recently been cloned and expressed in yeast. We treated four FA patients with a 2-week infusion of rh-SOD (25 mg/kg d daily) to determine whether rh-SOD had any effect on haemopoietic progenitor cell growth or on the abnormal cellular phenotype. We found that lymphocyte chromosomal aberrations induced by diepoxybutane were decreased during rh-SOD treatment in two patients and that bone marrow progenitors were increased in one patient.
