red blood cell glutathione deficiency

Three unrelated Japanese patients with chronic nonspherocytic hemolytic
anemia wer found to have marked deficiency of red blood cell (RBC) reduced
glutathoine (GSH) (4.4%, 13.1%, and 6.9% of normal, respectively). A panel
of RBC enzyme assays showed that one patient had decreased glutathione
synthetase activity and the other two were moderately deficient in
gamma-glutamylcystine synthetase. Some family members of each patient
showed mild deficiency of the respective enzymes. RBCs of these patients
also showed a decreased level of glutathione-S-transferase as in previously
described GSH-deficient cases. Hemolytic anemia was their only
manifestation, and neither 5- oxoprolinemia nor 5-oxoprolinuria, which are
usually associated with to generalized type of glutathione synthetase
deficiency, was noted in our patients.
