Background: Hepatitis A virus (HAV) infection is endemic in Iran. Detection of the seroprevalence of HAV is necessary to evaluate the feasibility of infection control strategies in the population. Objectives: This study aimed to determine the seroprevalence of HAV among blood donors as a representative sample of the general population. Methods: In this cross-sectional study, 268 blood samples were randomly selected from donors, presenting to the Iranian Blood Transfusion Organization in Sanandaj, Iran, in 2019. The collected sera were measured for anti-HAV antibodies (IgG and IgM), using ELISA assays. Also, demographic data, including age, gender, marital status, education, occupation, and blood donation status, were collected. The test results and demographic data were analyzed in STATA software. Results: The mean age of the blood donors was 37.79 ± 10.64 years, and 88.43% of them were male. Out of 268 blood samples, 218 (81.34%) were positive for anti-HAV antibodies. The antibody positivity was significantly correlated with age (P = 0.014) and marital status (P = 0.027). The majority of anti-HAV positive cases were found among farmers and ranchers (93.33%) (P = 0.045). Conclusions: A large proportion of blood donors had anti-HAV antibodies and were immune to HAV infection. Therefore, HAV was endemic in the study area.

En Afrique subsaharienne, les infections transmissibles par la transfusion sanguine comme la syphilis sont très répandues, avec une prévalence pouvant atteindre 25% chez les donneurs de sang. La présente étude avait pour objectif de déterminer la prévalence de la syphilis chez les donneurs de sang au niveau de la Banque du Sang d’Abéché. Nous avons mené une étude transversale à visée descriptive, qui s’est déroulée de mai à août 2017. Les échantillons de sang des donneurs ont été testés par immunochromatographie pour la détection des anticorps anti-tréponémiques (Biomnis®). Sur 789 donneurs de sang inclus dans l’étude, la prévalence de la syphilis était de 4,9 %. Les donneurs étaient à 96,1% de sexe masculin et 3,9% de sexe féminin. Cette prévalence était plus élevée chez les sujets âgés de [21-30] ans, chez les femmes, les donneurs non scolarisés, divorcés et les domestiques/ménagères habitant la zone d’Abéché urbaine. Ces résultats montrent qu’il est nécessaire de mettre en place une politique de suivi et de prise en charge médicale des donneurs de sang atteints de la syphilis.Mots clés: Transfusion sanguine, receveurs, Treponema pallidum, don de sang.   English Title: Prevalence of syphilis in blood donors at Abéché blood bank in ChadIn sub-Saharan Africa, infections transmitted by blood transfusion such as syphilis are widespread, with prevalence up to 25% in blood donors. The purpose of this study was to determine the prevalence of syphilis in blood donors at the Blood Bank of Abéché. It was a descriptive cross-sectional study, which ran from May to August 2017. Donor blood samples were tested by immunochromatography for the detection of anti-treponemal antibodies (Biomnis®). Of the 789 blood donors included in the study, the prevalence of syphilis was 4.9%. Donors were 96.1% male and 3.9% female. This prevalence was higher in subjects aged [21-30] years, women, out-of-school, divorced and domestic / household donors living in the urban Abéché area. These results shows that it is necessary to set up a policy of monitoring and medical care of blood donors with syphilis.Keywords: Blood transfusion, recipients, Treponema pallidum, blood donation.

Abstract Background: Millions of lives around the world are being saved annually through blood transfusion. However, blood transfusion is among the important vehicles for transmitting infections. The overall prevalence of Transfusion Transmissible Infections (TTIs) among blood donors differs around the world, reflecting the variation in the prevalence of these infections. The aim of this study is to assess the prevalence and trends of TTIs among blood donors in Qatar. Methods: This is a cross sectional study utilizing donation records of a five-year period from January 2013 to December 2017. Results for all screening and confirmatory tests for Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), Human T-Lymphotropic Virus-I/II (HTLV-I/II), Syphilis and Malaria were included in the study. Results: Among the 190,509 donations received at the donation center during the study period, about 91% donations were received from males and 9% from females. The overall positivity rate for all tests were 1.95, 2.18, 1.62, 1.81 and 1.85 for the years 2013 through 2017. The overall positivity rates for HBV, Syphilis and Malaria were 0.30, 0.43 and 0.20, respectively. Throughout the years, the positivity rates decreased for HBV, Syphilis and Malaria and increased for HCV and HTLV. Conclusion: The overall positivity rate of all tests combined for the TTIs demonstrated a gradual increasing trend from 2013 to 2017. The rates for HCV and HTLV showed increasing trends too. To support developing effective prevention and control strategies, further investigations are needed to improve the estimations of the prevalence of these infections.

ABSTRACT: PREVALENCE OF POSITIVE HBsAg BETWEEN VOLUNTARY BLOOD DONATIONS AND REPLACEMENT BLOOD DONATIONS AT PMI UTD LAMPUNG PROVINCE 2019-2020 Background: The risk of transmission of HBV infection through blood transfusion depends on many things, including the prevalence of disease in the community, the recipient's immune status, the number of donors per unit of blood, and the effectiveness of the screening used. The main disease transmission will occur during the window period, which is a period immediately after infection in which the donor's blood has been infected but the screening result is still negative.Objective: To determine the prevalence of positive HBsAg between voluntary blood donations and replacement blood donations at the PMI UTD in Lampung Province in 2019-2020. Methodology: The type of research used in this research is quantitative descriptive with cross-sectional design. The sample used in this study were blood donors at UTD PMI Lampung Province in 2019-2020.Results: The prevalence of voluntary blood donation with positive HBsAg in 2019 was obtained as many as 70 people (33.65%) while the prevalence of replacement blood donors with positive HBsAg in 2019 was obtained as many as 8 people (16%). Then, the prevalence of positive HBsAg voluntary blood donors in 2020 was found to be 138 people (66.35%) while the prevalence of positive HBsAg blood donors in 2020 was 42 people (84%).Conclusion: There is a difference in the prevalence of both voluntary blood donors and replacement blood donors between 2019 and 2020. and the prevalence of HBsAg positive in blood donors is different every year. Keywords: Blood Transfusion, Volunteer, Replacement, HBsAg  INTISARI: PREVALENSI HBsAg POSITIF ANTARA DONOR DARAH SUKARELA DENGAN DONOR DARAH PENGGANTI DI UTD PMI PROVINSI LAMPUNG TAHUN 2019-2020 Latar Belakang: Risiko penularan pada infeksi HBV melalui transfusi darah bergantung pada banyak hal, antara lain yaitu adanya prevalensi penyakit pada masyarakat, status imun resipien, jumlah donor tiap unit darah dan keefektifan skrining yang di gunakan.

BACKGROUND Even in the presence of sufficient voluntary blood donors, the need of blood is not met yet. We wanted to evaluate the causes that hinder the smooth functioning of well-maintained blood transfusion services (BTS). METHODS This is a population based cross-sectional study conducted among blood donors from voluntary outreach blood donation camp for period of one year. Total 1536 blood donors from 32 blood donation camps were subjected to study for the sociodemographic characteristic and their knowledge of blood donation. Statistical analysis of data was done using Microsoft Excel, analysed using statistical package for social sciences (SPSS) ver.16 software. RESULTS A total of 32 blood donation camps were conducted during the study period that provided 1536 donors. In most of the camps, male donors (75 %) were more than female donors. Donors of age group of 30 to 39 years (43.9 %) were more when compared to others. Donors those who were married accounted for 79.9 %. Blood donors of Hindu religion (53 %) were more. CONCLUSIONS The main hindrance for blood donor motivation is lack of knowledge. Literacy and chance to mingle in society have a positive effect on blood donor motivation. Targeting of effective donor motivation, recruitment, and retention were attained by conducting awareness classes, seminars, workshops, and visual communication modalities.

Background: Voluntary non-remunerated blood donation is a strategy adopted by World Health Organization aimed at ensuring safety and adequacy of blood supply. Sub-Saharan Africa has a high prevalence of hemoglobin disorders and therefore needs to adopt stringent measures in donor selection to ensure safety for the recipient of blood transfusion. This study aimed to analyze normal and variant hemoglobin among voluntary blood donors. Methods: In this descriptive cross-sectional study, 100 prospective blood donors including 55 (55%) males and 45 (45%) females, aged 18–34 years were recruited. Capillary electrophoresis using the Minicap system was used for determining the hemoglobin variants in alkaline buffer (PH 9.4). Data analysis was done using SPSS version 20 and p-value < 0.05 was considered as the level of significance Results: The mean age of the participants was 22.23 ± 3.3 SD years. The proportion of participants with genotype AA was 67 (67%), those with AS were 17 (22 %), while those with AC were 11 (11 %). While Hb A ≥ 90% was noted in 67 (67%) blood donors, Hb S was seen in 22 (22%) and Hb A2 > 3.5% in 57 (57%). Hb F > 2% was observed in 3% of the studied participants Conclusion: Variant hemoglobin is common among blood donors and this should be taken into consideration whenever blood is being crossmatched for recipients of blood transfusion. Data from this study will be useful in raising awareness and genetic counseling. Keywords: prevalence, hemoglobin variants, capillary electrophoresis

<p>Introduction<strong>: </strong>Blood donation is necessary in order to maintain an adequate supply of blood to patients who are suffering from any kind of disease or trauma, which requires them to have blood transfusion. Female non-blood donors are generally low in number.<strong> </strong>Therefore, this research was carried out to assess the main reasons behind the lack of blood donations made by females, and their knowledge, attitude and perceptions towards voluntary blood donation.</p> <p>Methodology: A cross-sectional study was conducted on 664 female health professionals, who were selected by non-probability convenience sampling from two tertiary care hospitals. A pretested questionnaire was presented to the sample population, and the data was entered and analyzed on SPSS (V17).</p> <p>Results: 94.6 % were aware with the fact that blood is screened for AIDS, Hepatitis B and C before transfusion. Moreover, 83.7% said that they will only donate blood if a family, relative or friend would need it and similarly 83.4%  suggested that they would donate blood if blood donation camps are arranged in hospital premises. 81.8 % thought that blood donors can contract Hepatitis B after donation where as only 29.5% did not blood due already blood loss in menstrual cycle.<strong></strong></p> <p>Conclusion<strong>: </strong>The participants had adequate knowledge about the benefits of blood donation. The most important reason identified for not donating blood is the lack of facilities within the workplace or lack of approach by responsible authorities. The results of the study may help in minimizing the misconceptions of the participants about blood transfusion, which would increase their contribution towards blood donation.</p>

Abstract Objective: Blood transfusion saves millions of lives. In Ethiopia, the need and the actual number of donations are not balanced. The actual reason is not clearly assessed however level of knowledge and attitude may be the main contributing factors. Thus, the current study aimed to assess blood donors’ knowledge and attitude towards blood donation at North Gondar district blood bank. Results: Of 401 blood donors, 142 (35.4%) and 379 (94.5%) of them had adequate knowledge and positive attitude, respectively. About 343 (85.5%) of study participants had no previous experience of blood donation. Perceptions of fear of pain, medically unfitness to donate and lack of information on when, where and how to donate blood were mentioned as reason for not donating blood. Educational status and residence were significantly associated with knowledge while participants with secondary and higher education were more likely to have good attitude towards blood donation. Thus, blood banks and others should design strategies for health education regarding blood transfusion. Keywords: Blood donation, Blood donors, Knowledge, Attitude, Gondar, Northwest Ethiopia

The Impact

Background and ObjectiveThe improved performance of serological tests has significantly reduced the risk of human immunodeficiency and hepatitis B and C viruses transmission by blood transfusion, but there is a persistence of residual risk. The objective of this study was to evaluate the impact of multiplex PCR in reducing the risk of residual transmission of these viruses in seronegative blood donors in Burkina Faso.MethodsThis cross-sectional study was conducted from March to September 2017. The serological tests were performed on sera using ARCHITECTSR i1000 (Abbot diagnosis, USA). Detection of viral nucleic acids was performed by multiplex PCR on mini-pools of seronegative plasma for HBV, HCV and HIV using SaCycler-96 Real Time PCR v.7.3 (Sacace Biotechnologies). Multiplex PCR-positive samples from these mini-pools were then individually tested by the same method.Results A total of 989 donors aged 17 to 65 were included in the present study. "Repeat donors" accounted for 44.79% (443/989). Seroprevalences for HIV, HBV, and HCV were 2.53% (25/989), 7.28% (72/989) and 2.73% (27/989), respectively. Of the 14 co-infections detected, HBV/HCV was the most common with 0.71% (7/989) of cases. Of 808 donations tested by multiplex PCR, 4.70% (38/808) were positive for HBV while no donation was positive for HIV or HCV.Conclusion: Our study showed a high residual risk of HBV transmission through blood transfusion. Due to the high prevalence of blood-borne infections in Burkina Faso, we recommend the addition of multiplex PCR to serologic tests for optimal blood donation screening.

Background Hepatitis A is a fecal-oral infection caused by hepatitis A virus (HAV). Men who have sex with men (MSM) and transgender women (TW) have been reported as target groups for HAV infection. This study aimed to determine the seroprevalence, risk factors, and circulating strains associated with HAV infection among MSM and TW in Central Brazil. Methods A cross-sectional study was conducted from November 2011 to September 2013. Serum samples were collected from 425 individuals for anti-HAV antibody testing and HAV molecular characterization. Of them, 149 (35.1%) participants were self-identified as transgender women. Statistical analysis was performed to evaluate the risk factors of HAV seropositivity. Results The seroprevalence of HAV exposure was 69.7% (95% Confidence Interval: 65.3–74.0%). Serological evidence of HAV was significantly higher in participants who self-identified as transgender women (83.2%) than MSM (62.3%). Increasing age, non-white race, and lower monthly household income were independently associated with HAV exposure among MSM. Only lower monthly household income was independently associated with HAV exposure among TW. One anti-HAV IgM positive sample, from a transgender woman (0.2%), was detected and classified as subgenotype IA. Conclusions High HAV prevalence was observed, markedly among TW. Considering the risky sexual behaviors this population is exposed to, HAV vaccination and prevention programs targeting this population should be considered to prevent outbreaks and the burden of the disease.

Blood donation is not readily an altruistic sacrifice in sub-Saharan Africa where microbial infections, maternal haemorrhages, malaria and other tropical diseases that frequently require blood transfusion are daily diagnoses. Blood transfusion safety is hindered by the combined prevailing high rate of Transfusion-Transmissible Infections (TTIs) and poor screening techniques. This study determined the rate of Enzyme-Linked Immuno-Sorbent Assay (ELISA) positive reactions to transfusion-transmissible infections in rapid diagnostic test negative family replacement blood units, compared to the first time voluntarily donated blood. We studied records of blood units collected in a tertiary hospital from donors who scaled pre-donation Rapid diagnostic test (RDT) screening for the human immunodeficiency virus, hepatitis B and hepatitis C viruses and syphilis and rescreened by ELISA techniques at the National Blood Transfusion Service Centre in Jos, along with units from first-time voluntary blood donors. A total of 19562 blood units; 5945 (30.39%) rapid diagnostic tests negative from a linkage hospital and 13617 (69.61%) from first time voluntary donors were screened by ELISA methods for HIV, HBV, HCV, and syphilis. The overall TTIs detected by ELISA was 16.08%, significantly lower among pre-donation rapid screened family replacement blood donors [495(8.32%)] compared to 2651 (19.47%) among first-time voluntary donors; P=0.0001. Fifty-seven (0.96%) HIV, 166 (2.79%) HBV, 137 (2.31%) HCV and 137 (2.31%) syphilis were still detected respectively by ELISA in the pre-screened negative family replacement blood units. The outcome of ELISA screenings of blood collected from first-time volunteer donors were; 143 (1.05%) HIV, 1,486 (10.91%) HBV, 683 (5.02%) HCV, and 339 (2.49%) syphilis. Blood for transfusion should be screened negative at least with ELISA.
