Özet

Background: We tried to understand whether or not there is an association between prevalence of autosplenectomy and severity of sickle cell diseases (SCDs). Methods: All SCDs patients with red blood cell (RBC) transfusions of less than 50 units in their lives were put into the first group and 50 units or higher were put into the second group. Results: The study included 316 patients (155 females). There were 224 cases (70.8%) in the first group and 92 cases (29.1%) in the second group (p<0.001). The male ratio was significantly higher in the second group (64.1% versus 45.5%, p<0.001). Although both the white blood cell and platelet counts were higher in the second group, there was a significant difference in platelet counts (p=0.005), and this was probably due to the small sample sizes. Although the prevalence of autosplenectomy was significantly higher in the first group (56.2% versus 45.6%, p<0.05), the mean number of painful crises per year, digital clubbing, chronic obstructive pulmonary disease (COPD), leg ulcers, stroke, chronic renal disease (CRD) and coronary heart disease (CHD) were significantly higher in the second groups (p<0.05 for all). Conclusion: In contrast to the lower prevalence of autosplenectomy, the mean number of painful crises per year, digital clubbing, COPD, leg ulcers, stroke, CRD, and CHD were significantly higher in the second group. So there may be an inverse relationship between prevalence of autosplenectomy and severity of SCDs, and spleen may act as a chronic inflammatory focus as a filter of blood for these abnormally hard RBCs.
