RESUMEN
Objectives: The objective of the study is to present the demographic characteristics, clinical and laboratory features and outcome of our patients with hereditary spherocytosis (HS). Methods: Demographic, clinical, and laboratory data; complications; and splenectomy results were analyzed retrospectively. The severity of the disease was scaled according to Eber's criteria. Results: Sixty-nine patients (42 boys, 27 girls, median age: 3 years) were eligible. Sixty-eight percent of the patients had a history of neonatal jaundice. The complaints at admission were jaundice (71%), fatigue (27.5%), fainting (4.3%), and pallor (4.3%). The median follow-up duration was 8.5 years. According to Eber's criteria, three (4.3%), 57 (82.6%), and nine (13.1%) patients had mild, moderate, and severe diseases, respectively. Thirty-six patients (52.1%) had a splenectomy. Following splenectomy, we observed a significant rise in hemoglobin levels and a decline in indirect bilirubin levels. Post-operative thrombocytosis was common, with a tendency to fall and stabilize after 1 month. There were no thromboembolic complications. Conclusion: In spite of the high rate of consanguinity, familial history of HS, and neonatal jaundice in our study group, the majority of the HS patients were identified relatively late, about 3 years. This finding shows that HS might be insufficiently acknowledged by primary care. Splenectomy, in selected cases, may reduce the need for transfusions. Post-splenectomy transient thrombocytosis is common and has a benign course.
