INTRODUCTION: Seventy-six samples were collected from sixteen canine blood donors at every blood donation performed in accord with the canine donor selection guidelines. Statistical analysis of ELISA OD values revealed no significant variation of anti-rabies antibodies values during repeat donations. Our results support the statement that blood donation does not affect the immune status of donors. OBJECTIVES: The study aimed to assess the immune status against rabies among the canine blood donors in a Romanian canine blood bank METHODS: Serum samples (n=76) were collected from pet owned dogs (n=16) recorded in the blood bank register of a Romanian blood bank were performed with the immunological status of the investigated canine blood donors was evaluated using the indirect ELISA commercial kit PLATELIA RABIES II (BIO-RAD, France) as per the manufacturer's instructions RESULTS: The overall picture of ELISA OD results revealed non-significant variation between and within D1-D6 groups of values (p>0.05, F<Fcrit). CONCLUSION: The next studies topic would be to compare the results provided by the ELISA technology with FAVN.

Aim: Hepatitis E virus (HEV) transmission through blood transfusion is a major public health issue worldwide. We aimed to determine the seroprevalence of HEV in blood donors in the Qassim region of Saudi Arabia. Materials & methods: Serum samples (n = 1078) were collected from volunteer blood donors and tested for the presence of anti-HEV IgG and IgM by indirect ELISA. Results: The seroprevalence of anti-HEV IgG among the blood donors was 5.7% overall. Anti-HEV IgG and IgM seropositivity were significantly higher in non-Saudi donors than in Saudi donors (22.1 vs 3 and 7.8 vs 0.2% for anti-HEV IgG and IgM, respectively). Conclusion: The seroprevalence of HEV among blood donors in the Qassim region was lower than previous estimates for other regions of the country and neighboring countries.

The existence and sustenance of the blood bank depends on blood donors. It is imperative that the donation experience is satisfactory for the donors. Therefore this study was carried out to determine the frequency of undesirable events experienced by the blood donor as part of donor haemovigilance. This was a retrospective descriptive study of the events that occurred amongst the blood donors of the blood bank of a tertiary institution. The blood donor incident book was reviewed for the period of six months. Negative undesirable events occurred in 2% of the donor populations, of which 45.8% could not complete the blood donation process while only 16.7% completed the blood donation process. Mild vasovagal attack occurred in 0.2% of the donor population. Undisclosed deferrable risk factors/ behaviours were identified by the phlebotomist in the bleeding room which made donors unfit for donation even though they had passed the donor screening criteria. This accounted for 20.8% of those with negative experience. Guidelines are required to identify donors that are not likely to complete donation to avoid wastage of time, blood, resources and reduce undesirable experiences.

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.

In this study the raising and development of the immune response to Borrelia burgdorferi infection in 45 Italian patients suffering from culture-confirmed Lyme borreliosis erythema migrans was investigated. A total of 95 serially collected serum samples were tested by using three different commercial ELISAs: recomWell Borrelia (Mikrogen), Enzygnost Borreliosis (DADE Behring) and Quick ELISA C6 Borrelia (Immunetics). The sensitivities of the ELISAs were as follows: Enzygnost Borreliosis IgM, 70.5 %; Quick ELISA C6 Borrelia, 62.1 %; recomWell Borrelia IgM, 55.7 %; recomWell Borrelia IgG, 57.9 %; and Enzygnost Borreliosis IgG, 36.8 %. In order to compare the specificity values of the three ELISAs, a panel of sera obtained from blood donors (210 samples coming from a non-endemic area and 24 samples from an endemic area) was tested, as well as sera from patients suffering from some of the most common biological conditions that could result in false-positive reactivity in Lyme disease serology (n = 40). RecomWell Borrelia IgG and recomWell Borrelia IgM were the most specific (97.1 % and 98.9 %, respectively), followed by Quick ELISA C6 Borrelia (96.7 %). Enzygnost Borreliosis IgG and IgM achieved 90.1 % and 92.3 % specificity, respectively. Sera that gave discrepant results when tested by the three ELISAs were further analysed by Western blotting.

Context: The current regulatory requirements for donor eligibility pose a challenge to blood centers in recruitment of voluntary blood donors, particularly in a developing country like India where awareness of the general population is low and myths about blood donation are prevalent. This study evaluates the reasons and rates of donor deferral in a tertiary hospital-based blood bank in western India.Aim: To find rates and reasons for deferral of voluntary blood donors in a city in western India.Settings and design: A retrospective study was done on blood donors during a 3-month period. Data collection was done by electronic records of blood donors.Materials and Methods: The study was conducted retrospectively at a tertiary care hospital in western India. All those who donated whole blood between 1st January 2011 and 31st March 2011 were included in the study. Data was collected using local blood bank software.Statistical analysis used: No statistical technique used as it is a data article.Results: 60.5% of donors were young, below 30 years of age. Donors were predominantly male (91.6%). Voluntary donors comprised 88% of the donors. Total deferral rate was 22.36%, with 17.29% permanent deferrals and 82.71% temporary deferrals. Main reasons for deferral were anemia 39.42%, low body weight 14.29%, hypertension 10.73%, age below 18 years 10.73% and history of medication 6.09%. The common causes of deferral between our study and other similar studies are the same.Conclusion: We concluded that majority of the donor population belongs to 18–30-year-old age group. This is encouraging with a voluntary blood donation initiative. Donor self exclusion and strict donor selection criteria application should be addressed by more proactive measures to make blood donation a safe and pleasurable experience.

Microbiological safety is very important aspect of blood transfusion services (BTS). Viral infectious agents possess a great risk of transfusion transmitted disease. On the one hand, blood or component transfusion is a lifesaving modality but on the other hand it can cause great mortality or morbidity in recipient if not used judiciously. The main aim of the study is to evaluate the prevalence of HIV, HBV, HCV, Syphilis and Malaria amongst all types of donors donated at blood bank of Sir Sunderlal Hospital, Institute of Medical Sciences, Banaras Hindu University, Varanasi during the year 2017. This was a retrospective study. The blood donors included in this study include all donors coming directly to blood bank and blood donation camps organized by blood bank. Total donation during that period was 22255 units. A detailed questionnaire was given to the donors for registration. A total of 226 units (1.01%) were seropositive. The sero-prevalence of HIV, HBV, HCV, and Syphilis were 0.9% (21), 0.79% (177), 0.09% (22), 0.02% (6) respectively. No cases of malaria were detected. TTI can be reduced by motivating maximum voluntary blood donation, reducing replacement donation, public information and donor education awareness programme, stringent donor screening criteria and vigilance of error.

Blood is one of the fundamental tissues of our body. Blood donation allows blood banks to meet hospital needs for blood components. Blood transfusion is an activity that carries a risk, originated by a series of causal actions derived from the individual characteristics of donors and patients. Blood components are biological products and as such, they can never be exempt from the risk of transmitting infectious diseases, such as hepatitis B, HIV, syphilis, among others. Thanks to the investigation of the donor database of the Blood Bank of Hospital Dr. Carlos Luis Valverde Vega and the annual statistics of the blood bank, the statistics referring to donations were obtained, according to the type, grade of acceptance and as well as the prevalence of mandatory screening infectious diseases in the blood bank, between the years 2015 and 2019, with the respective authorization of the corresponding scientific ethics committee. This study reported a prevalence for Anti HB Core of 0.99%, 0.14% for HBsAg, 0.11% for syphilis, 0.05% for hepatitis C, 0.02% for HIV and 0% for the disease de Chagas and HTLV I / II. By using the bases of this work, future analyzes with a similar premise may be developed in different blood banks of the different health centers in our country.

Background: India has the second highest HIV population in the world with about 2.5-3.0 million cases. Blood transfusion saves millions of lives worldwide each year but Blood transfusion is an important mode of transmission of infections to recipients and at the same time it is also associated with large number of complications including transfusion-transmissible infections (TTIs). Aims & objective: to study the prevalence of HIVin blood donors of A.D.Gorwala Blood bank From January 2005 To December 2010. Methods: A retrospective study was conducted among blood donors through the years 2005-2010. Sera from blood donors were tested for the detection of Anti HIV by using third generation ELISA tests, strictly following the instruction of manufacturers. The donor information was collected through the donor registers from A.D. Gorwala Blood Bank. Result: From the total of 28,371 screened blood samples collected, the prevalence of HIV in blood donors in the blood bank was 0.23% in the ve consecutive years but the trend of HIV infection has decreased from 2005(0.31%) to 2010 (0.04%). The age groups18-30 has the highest prevalence and the age group 51-60 was the lowest prevalence of HIV infection. The Prevalence of HIV among male (0.18%) was higher than in female donors (0.05%). The trend of HIVinfection was decreasing for both male and female blood donors. Conclusion: The analysis of HIV seroprevalence among blood donors through the year 2005- 2010 showed a signicantly decreasing trend, probably due to the cumulative effect of increasing awareness of HIVand improved screening system for safe blood donation.
