Splenectomy in children with sickle cell disease and thalassemia
Insights
Splenectomy in children with sickle cell disease and thalassemia can reduce or eliminate the need for blood transfusions and improve blood counts. This procedure offers a valuable option for carefully selected pediatric patients with these blood disorders.
Area of Science:
- Pediatric Hematology
- Surgical Oncology
- Genetics
Background:
- Sickle cell disease and thalassemia are inherited blood disorders requiring significant medical management.
- Splenomegaly and hypersplenism are common complications, often necessitating interventions like blood transfusions.
- Splenectomy is a surgical option considered for managing complications in these conditions.
Purpose of the Study:
- To evaluate the outcomes of splenectomy in Saudi children diagnosed with sickle cell disease and thalassemia.
- To assess the impact of splenectomy on transfusion requirements and hematological parameters.
- To determine the safety and efficacy of splenectomy in this pediatric population.
Main Methods:
- A retrospective study of 31 Saudi children with sickle cell disease and thalassemia who underwent splenectomy.
- Patients were categorized based on the indication for splenectomy: frequent blood transfusions, chronic hypersplenism, or splenic abscess.
- Hematological parameters and transfusion needs were analyzed pre- and post-splenectomy, with prophylactic measures for pneumococcal infection administered.
Main Results:
- Splenectomy was performed for various reasons, including hypersplenism (15 patients) and frequent blood transfusions (12 patients).
- Post-splenectomy, 16 patients no longer required blood transfusions, and 7 others had significantly reduced transfusion needs.
- Significant improvements were observed in hemoglobin, RBC, and platelet counts, alongside a decrease in reticulocyte counts in patients with hypersplenism.
Conclusions:
- Splenectomy is a beneficial procedure for selected children with sickle cell disease and thalassemia, particularly those with transfusion-dependent anemia or hypersplenism.
- The study demonstrates a reduced need for blood transfusions and improved hematological indices post-splenectomy.
- While complications like chest infection can occur, splenectomy offers a defined role in managing these severe pediatric blood disorders.
Abstract:
A number of Saudi children (31) with sickle cell disease and thalassemia underwent splenectomy: 12 for frequent blood transfusions, 15 for chronic hypersplenism (most of whom were also the recipients of periodic blood transfusion) and 4 for splenic abscess. The mean age of splenectomy was 8.8 years (8 months-18 years). Eight patients had sickle cell disease, 14 beta-thalassemia and 9 had sickle cell thalassemia. All patients received prophylaxis against pneumococcal infection. There was one postoperative death most probably due to sepsis. Sixteen of those who required frequent preoperative blood transfusions needed no more transfusions, while in 7 the need for transfusions decreased significantly (p less than 0.05). For those with hypersplenism, there was a significant postoperative increase in total hemoglobin (P less than 0.001), RBC (P less than 0.001) and platelet counts (p less than 0.02); and a substantial decrease in reticulocyte counts (p less than 0.05). The common post splenectomy complications were chest infection and a brief episode of pyrexia, but without undue morbidity. The study establishes a definite place for splenectomy in a selected population of children with sickle cell disease and thalassemia.
