Abstract
To determine the clinical and hematologic features of 68 children with hereditary spherocytosis (HS). In this retrospective study, we analyzed recorded information of 68 HS patients diagnosed between March 1997 and March 2007, including clinical manifestations at admission, gender, median age at diagnosis, family history, hematologic and biochemical data, patient management, complications, median age of splenectomy, and median follow-up time. Sixty-eight patients with HS (36 male and female) were investigated. The median age at diagnosis was 5.6 years (range 3 months to 18 years). Twenty-seven (39.7 %) had parents with consanguineous marriages, and 20 (29.4 %) had parents with first-degree consanguinity. Predominant clinical manifestations at admission were anemia in 59 patients (86.76 %), splenomegaly in 49 (72.05 %), and jaundice in 33 (48.52 %). Patients were classified as mild, moderate, or severe in 29.4, 61.7, and 8.8 % of patients, respectively. Five patients (7.3 %) underwent splenectomy. Major complications of HS were hemolytic, aplastic, and megaloblastic crises and cholelithiasis in 7 (10.2 %), 1 (1.4 %), 7 (10.2 %), and 6 (8.8 %) of patients, respectively. There were no deaths during follow-up. HS should be considered in evaluating possible diagnoses in patients with hemolytic anemia. In this study, the clinical course of patients with HS was relatively benign, with low proportions of patients having splenectomized and aplastic crises.
