Abstract/OtherAbstract:
The association of sickle cell trait (SCT) and hereditary spherocytosis (HS) has been reported in only 18 patients. Three of these 18 patients experienced splenic infarct or acute splenic sequestration. We report here a 46-year-old African-American male, the oldest reported case to date, who experienced episodes of hemolysis and severe left upper quadrant pain for the past 26 years. The patient had compensated hemolysis with splenomegaly. A CT scan of the abdomen revealed a large infarct in the spleen. The diagnosis of SCT was confirmed with isoelectric focusing, cation exchange and reverse-phase HPLC. The presence of a silent, interacting globin variant as the cause of hemolysis and sickling in the spleen was ruled out by sequencing of the alpha1-, alpha2- and beta-globin genes. The diagnosis of HS was established by an osmotic fragility test. The interaction of HS and SCT leads to RBC dehydration with increased MCHC and intracellular Hb S concentration presumably favoring intrasplenic sickling and resultant splenic infarcts and sequestration as seen in this case.
