BACKGROUND AND OBJECTIVE: Assessment of Hemoglobin S trait donors has gained importance together with the increased allogeneic peripheral stem cell transplant activity for sickle cell disease in the regions where the disease is prevalent. Outcomes of Granulocyte-Colony Stimulating Factor (G-CSF) administration are obscure for hemoglobin S trait donors. This study aims at investigating the incidence of hemoglobin S carrier status and outcomes of G-CSF administration among donors who live in Eastern Mediterranean region. MATERIAL AND METHOD: The cross-sectional, single-center cohort study was performed with 147 donors between January 2013 and March 2017. Prevalence of hemoglobin S trait was estimated and subjects with or without Hemogobin S trait were compared with regard to stem cell characteristics, early and late clinical outcomes after G-CSF administration. RESULTS: Eleven out of 147 donors (7.48%) were found as hemoglobin S trait. G-CSF administration was successfully completed and yielded good harvesting results in hemoglobin S trait donors. No statistically significant difference was found between groups with regard to early and late side effects, stem cell characteristics. Blood pressures and QTc values were within normal ranges in both groups. Groups were similar with regard to CD34 values. CONCLUSION: G-CSF seems safe in hemoglobin S trait donors. Their being eligible as donors would increase the chance of the patients for allogeneic stem cell transplantation in high prevalence regions. Further studies are required to reveal the safety profile of G-SCF in hemoglobin S carriers in different regions.

OBJECTIVE: Obtaining informed consent from hematopoietic stem cell recipients and donors is a critical step in the transplantation process. Anxiety may affect their understanding of the provided information. However, use of audiovisual methods may facilitate understanding. In this prospective randomized study, we investigated the effectiveness of using an audiovisual method of providing information to patients and donors in combination with the standard model. MATERIALS AND METHODS: A 10-min informational animation was prepared for this purpose. In total, 82 participants were randomly assigned to two groups: group 1 received the additional audiovisual information and group 2 received standard information. A 20-item questionnaire was administered to participants at the end of the informational session. RESULTS: A reliability test and factor analysis showed that the questionnaire was reliable and valid. For all participants, the mean overall satisfaction score was 184.8±19.8 (maximum possible score of 200). However, for satisfaction with information about written informed consent, group 1 scored significantly higher than group 2 (p=0.039). Satisfaction level was not affected by age, education level, or differences between the physicians conducting the informative session. CONCLUSION: This study shows that using audiovisual tools may contribute to a better understanding of the informed consent procedure and potential risks of stem cell transplantation.
