Blood donors’ attitudes towards incentives: influence on motivation to donate

Background. Understanding the factors that motivate donors to donate will facilitate improvements in recruitment programmes. Donation incentives are often used to improve the effect of recruitment programmes. This cross-sectional study was designed to understand donors' attitudes toward incentives. Material and methods. Participants (n=421) were recruited among volunteer donors at the Shiraz Blood Transfusion Centre when they registered for blood donation. They completed a questionnaire with items regarding demographic characteristics, donation status (fi rst-time donor or regular donor), and their motivation for donating, their attitude towards incentives, and the best type of incentives. Multiple logistic regression and chi-squared tests were used to analyse the data with Statistical Package for the Social Sciences (SPSS) software. Results. The majority of donors (85.6%) donated blood for altruistic reasons. One quarter of the donors (25.3%) believed that incentives should be offered to encourage them to donate. Most donors (84.5%) believed that the most effective incentive was offering specifi c blood tests. Donors who had donated for non-altruistic reasons were more interested in receiving incentives. The desire to receive incentives was more widespread among younger, married, fi rst-time donors, donors with a lower educational level and donors with a history of more than fi ve donations. The desire to receive incentives decreased as age increased. Discussion. Most of the donors (74.7%) had no desire to receive incentives, and this was even more apparent among donors who donated for altruistic reasons. Non-monetary incentives may be effective in attracting younger, married, fi rst-time donors, donors with a lower educational level and donors with a history of more than fi ve donations

Transfusion-Transmitted Malaria in Iran: A Narrative Review Article

Background: Malaria is the most important transfusion-transmitted infection (TTI) in worldwide after viral hepatitis and human immunodeficiency virus (HIV) infection. The main objective of the present study was to review and evaluate the transmission of malaria via blood transfusion in Iran. Methods: A literature search was done without time limitation in the electronic databases as follows: PubMed, Scopus, Google Scholar, Web of Science, Science Direct, scientific information database (SID), Magiran, IranMedex and Irandoc. The searches were limited to the published papers to English and Persian languages. Results: Six papers were eligible. From 1963 to 1983, 344 cases of Transfusion-transmitted malaria (TTM) had been reported from different provinces of Iran. The most prevalent species of involved Plasmodium in investigated cases of TTM was Plasmodium malariae (79.24%). The screening results of 1,135 blood donors for malaria were negative by microscopic examination of peripheral blood smears and rapid diagnostic test (RDT) methods. Conclusion: Lack of TTM report from Iran in the last three decades indicates that the screening of blood donors through interviewing (donor selection) may be effective in the prevention of the occurrence of transfusion-transmitted malaria

Evaluation of platelet aggregation in splenectomized beta-thalassemia major and intermedia patients

BACKGROUND: Platelet dysfunction may be one of the pathophysiologic complications in beta-thalassemia patients. However, the results obtained from the platelet aggregation vary in different types of β-thalassemia and among patients. OBJECTIVE: We evaluated the platelet function to determine risk of thrombosis in two groups': beta-thalassemia major (TM) and intermedia (TI). MATERIALS AND METHODS: In a cross-sectional study, platelets of 82 adult patients with beta-thalassemia (46 β-TM and 36 β-TI) who had undergone splenectomy and 85 normal healthy individuals as control were induced by collagen 10 μ g/ml, adenosine diphosphate (ADP) 20 μ M/l, arachidonic acid 500 μ M/l, and ristocetin 1500 μ g/ml. Independent t-test was used to compare the mean values using SPSS 16. P < 0.05 was taken to indicate statistical significance. RESULTS: Although a significant increase was observed in the platelet aggregation by collagen, ADP, and arachidonic acid in β-TM patients as compared with healthy controls, the β-TI patients showed no difference (P < 0.05). There was no significant alteration in response to ristocetin in β-TM but it reduced in β-TI. CONCLUSIONS: The platelet aggregation in β-TM patients is more than β-TI, both of whom splenectomized. The platelet aggregation in beta-thalassemia might be impressed by transfusion. Given these changes, thrombotic risk should be considered in beta-thalassemia patients

Evaluation of new cases of HCV infection in thalassaemia patients for source of infection

Background: Screening tests on blood bags is important step for blood safety. In Iran, screening for HCV started from 1996. We decided to determine the new cases of hepatitis C in our thalassemic patients, after screening of blood bags was initiated and trace backing from recipients to find their donors. Materials and Methods: The study was done on patients with complete files for HCVAb test results. Only cases that had a positive HCVAb result following a negative result were considered as new cases. For trace backing, we recorded the blood transfusions&#x2032; date and the blood bags&#x2032; number from last negative test results (HCVAb) to the first positive test result. These data were sent to the transfusion center. The suspected donors were contacted and asked to be tested again in the transfusion center. Results: A total of 395 patients were studied; 229 (58&#x0025;) males and 166 (42&#x0025;) females. Mean age was 27.5 years. We had 109 HCV (27.5&#x0025;) positive cases of whom 21 were infected after 1996. We traced the last five cases contaminated during 2003 and 2004. These five patients had 13, 10, 13, 12, and 6 donors, respectively (totally 54 donors were found). We proved the healthy state in 68.5&#x0025; (37 of 54) of our donors population. Of them, 81&#x0025; were repeated donors and 17 of 54 donors (31.5&#x0025;) could not be traced (because of change in addresses). We did not have any HCV new cases after 2004. Conclusion: We could not prove HCV transmission from donors as the source of infection. Although parenteral transmission is always on top of the list in HCV infection, the possibility of hospital and/or nursing personnel transmission and/or patient-to-patient transmission such as use of common instruments like subcutaneous Desferal&#174; infusion pumps; which the patients used for iron chelation therapy, should also be kept in mind

Seroprevalence and risk factors of hepatitis a virus infection in Iran: A population based study

Background: In older studies, the seroprevalence of hepatitis A virus infection has been reported to be over 95% in Iranians. Most of these studies were performed on volunteer blood donors. Studies on the general population are sparse. The purpose of this study was to determine the current seroprevalence of hepatitis A virus infection in the general population of Iran. Methods: During 2006, 1869 subjects between 18 and 65 years of age were randomly selected from the general population of three Iranian provinces (Tehran, Golestan, and Hormozgan). Subjects were interviewed and a plasma sample was obtained for serologic testing for antihepatitis A virus. Univariate and multivariate analysis was performed to identify risk factors. Results: The seroprevalence of hepatitis A virus in Tehran, Golestan and Hormozgan was 85%, 99%, and 96%, respectively. The overall seroprevalence of hepatitis A virus in the general population of the three provinces studied was 86% and did not differ between the two genders. The prevalence in younger subjects and in urban populations was under 70%. In multivariate analysis, older age, being married, and level of the father\u27s education was associated with hepatitis A virus seropositivity. Conclusion: The seroprevalence of hepatitis A virus still appears to be too elevated for recommending routine vaccination in the general population. However, the trend towards a lower prevalence in younger age groups and people from urban areas points towards the possible benefit of vaccination in these subgroups

Seroprevalence of hepatitis C virus: The first population-based study from Iran

Objective: Early studies on blood donors point to a seroprevalence of approximately 0.25% for hepatitis C virus (HCV) infection in Iran. However, the true prevalence in the general population is unknown. The objective of this study was to determine the prevalence of HCV infection in the general population of Iran. Methods: We randomly selected 6583 subjects from three provinces in Iran for inclusion in the study. Subjects were aged between 18 and 65 years. Anti-hepatitis C antibody was tested by a third-generation ELISA test. A recombinant immunoblot assay (RIBA) test was used to confirm the results. Risk factors were recorded and a multivariate analysis was performed. Results: A total of 5684 plasma samples were tested. After confirmatory tests, we found 50 cases of HCV. The overall weighted prevalence of anti-HCV was 0.5%. The rate was significantly higher in men (1.0%) than in women (0.1%). In multivariate analysis, male sex, history of intravenous drug abuse, and imprisonment were significantly associated with anti-HCV. Conclusions: We found the prevalence of HCV infection in Iran to be higher than previous estimates. It appears that the rate is rising, and in the future, hepatitis C will replace hepatitis B as the most common cause of chronic viral liver disease in Iran. © 2010 International Society for Infectious Diseases
