  • Title: Sulfonamide-induced hemolytic anemia and hemoglobin Hasharon.
    Author: Adams JG, Heller P, Abramson RK, Vaithianathan T.
    Journal: Arch Intern Med; 1977 Oct; 137(10):1449-51. PubMed ID: 921425.
    Abstract:
    A patient with Hb Hasharon had severe hemolytic anemia after several days of daily ingestion of 2 gm of sulfisoxazole. After recovery, her erythrocytes were incubated with the drug, leading to preferential oxidation and precipitation of the abnormal hemoglobin. Since carboxyhemoglobin and cyanmethemoglobin Hasharon were as stable in the heat stability test as identically liganded Hb A, we conclude that the substitution of the hydrophilic aspartate residue by histidine on the surface of the molecule at alpha47 has led by a still unknown mechanism to an interaction of hemoglobin with the drug that labilized the heme-globin bond. Since Hb Hasharon has been found in several unrelated families, the risk of drug-induced hemolytic anemia in such carriers deserves emphasis.
