    Purpose: We aimed to investigate erythrocyte alloimmunization frequency and related factors in our region where SCD is common Material and Methods: This study was planned as a single center, cross-sectional and retrospective cohort study. A total of 216 patients who had been followed up due to SCD [Hemoglobin (Hb) SS, Hb S-beta thalassemia, Hb S-alpha thalassemia] were included in this study. Patients were divided to two groups according to amount of transfusion. The patients who had received less than 6 transfusions per year and who did not have the history of erythropheresis were allocated to Group 1, and the patients who had received 6 or more simple transfusion per year or who had undergone erythrocyte exchange were allocated to Group 2 Results: Of 216 SCD patients included in the study. Alloimmunization was detected in 67 (31.0%) out of 216 patients who underwent transfusion, and in 17 (30.4%) out of 56 patients in Group 1 and in 50 (31.3%) out of 160 patients in Group 2. When the patients were analyzed according to alloimmunization development, our study revealed that neither SCD complications are a risk factor for alloimmunization nor alloimmunization increases mortality rates Conclusion: High alloimmunization frequency found in our study suggests the insufficient adherence of alloimmunization-prevention policies in RBC transfusions performed except experienced institutions. Therefore alloimmunization may be reduced or prevented through performing extended red cell typing among SCD patients

    Pulmonary complications in adult patients with sickle cell disease
    (2018) Sen, Nazan
    Sickle cell disease (SCD) is an inherited hemoglobin disorder, associated with recurrent painful episodes, ongoing hemolytic anemia and progressive multi-organ failure. While survival beyond the fourth decade of life for a patient with SCD was previously considered unusual; nowadays, in countries with developed health care systems, patients with SCD could reach into adulthood. However, irreversible organ damages have become more prevalent along with the patients' reaching adulthood. The lungs as well are among the organs involved in SCD. Pulmonary complications are significant causes of morbidity and mortality and are substantially responsible for deaths. Although our understanding of these conditions has improved over the past 10-15 years, there remains no specific treatment of pulmonary complications of SCD. Limited data on health care issues, particularly in older adults with SCD, poses multiple challenges to patients, their families and health care providers. The incidence and severity of pulmonary complications require the physicians' further interest in this subject. The present review comprises the following pulmonary complications of SCD: i) acute chest syndrome, ii) venous thromboembolus, iii) asthma, iv) respiratory dysfunction, v) respiratory disorders during sleeping, vi) pulmonary hypertension.
