Introduction: This study investigated the seroprevalence of hepatitis B virus surface antigen (HBsAg), antibody against hepatitis C virus (anti-HCV), antibody against human immunodeficiency virus type 1/2 (anti-HIV 1/2), and antibody against Treponema pallidum (anti-Treponemal or syphilis antibody) in healthy volunteer blood donors, and assessed their distribution according to the years and genders. Methodology: HBsAg, anti-HCV, anti-HIV ½, and syphilis screening results of a total of 266,035 healthy volunteer blood donors who had been admitted for blood donation to the Regional Blood Center of Dicle University Hospital between January 2000 and December 2010 were evaluated, retrospectively. HBsAg, anti-HCV, and anti-HIV 1/2 screening were performed using a fully automated device with the microparticle enzyme immunoassay method (MEIA). Syphilis screening was performed by Rapid Plasma Reagin (RPR) carbon test between January 2000 and December 2009, and by using a fully automated device with the MEIA method between January 2010 and December 2010. Results: Of 266,035 healthy volunteer blood donors, 259,384 (97.5%) were male and 6,651 (2.5%) were female. Statistically, there was not any significant difference between male and female genders for HBsAg, anti-HCV and syphilis seropositivities (P = 0.729, P = 0.748, and P = 0.861, respectively). HBsAg was found to be positive in 8,422 (3.17%), anti-HCV in 1,703 (0.64%), anti-HIV 1/2 in one (0.0004%) of 266,035 healthy volunteer blood donors, and syphilis antibody with RPR in 166 (0.07%) of 246,341 healthy volunteer blood donors. Conclusion: Blood donor forms should be carefully tailored to improve the identification of possible risks of transfusion-transmitted infections.

F.VIII R:Ag was determined by quantitative immunelectrophoresis (I.E.) with a prefabricated system. The prefabricated system consists of a monospecific f.VIII rabbit antiserum in agarose on a plastic plate for the one and two dimensional immunelectrophoresis. The lognormal distribution of the f.VIII R:Ag concentration in the normal population was confirmed (for n=70 the f.VIII R:Ag in % of normal is = 95.4 ± 31.9). Among the normal population there was no significant difference between blood donors (one blood donation in 8 weeks; for n=43 the f.VIII R:Ag in % of normal is = 95.9 ± 34.0) and non blood donors (n=27;f.VIII R:Ag = 94.6 ± 28.4 %). The f.VIII R:Ag concentration in acute hepatitis B ranged from normal to raised values (for n=10, a factor of 1.8 times of normal was found) and was normal again after health recovery (n=10, the factor was 1.0). in chronic hepatitis the f.VIII R:Ag concentration was raised in the majority of the cases (for n=10, the factor was 3.8). Out of 22 carrier sera 20 showed reduced, 2 elevated levels of the f.VIII R:Ag concentration. in 5 sera no f.VIII R:Ag could be demonstrated. The f.VIII R:Ag concentration was normal for n=10, reduced for n=20 and elevated for n=6 in non A-non B hepatitis (n=36). Contrary to results found in the literature no difference in the electrophoretic mobility of the f.VIII R:Ag was found between hepatitis patients sera and normal sera.

Hiv 1

AIDS virus (HIV) transmission by transfusions and blood products has been essentially halted in industrialized countries which haye introduced systematic anti-HIV screening of donations in 1985. New anti-HIV screening assays, based in part on the replacement of disrupted HIV virions by defined DNA recombinant HIV antigens, have improved specificity; sensitivity has been improved as to dectect seroconversion at an earlier stage. Confirmatory assays and (self-)exclusion of risk groups from blood donation do remain mandatory. HIVAg can be detected in some infections before antibody conversion, and HIVAg is more likely to be found in those anti-HIV positives who proceed to disease. However, there is no justification so far for routine parallel HIVAg and anti-HIV screening. There is continued uncertainty how many HIV carriers have not (yet) developed antibody, but their numbers may have been overestimated. Studies to determine how many HIV transmitters have escaped blood bank detection, and why, need to be undertaken in spite of formidable logistic difficulties.The risk of developing AIDS is now estimated at 25-50 % within 10 years after the infectious contact. It is not clear whether the risk should be estimated differently in different groups or persons. In cities in Central Africa, 5-20 % of men and women are confirmed anti-HIV positives. At least 75 % of this HIV carrier rate is due to heterosexual transmission. Heterosexual transmission has been slower in Western countries, but factors precluding slow evolution to high figures by the same route outside Africa have not been identified. Therefore, countries have no choice in advocating behaviour changes in the general population, and not only in the classical risk groups. Initial hesitations toward extended voluntary and confidential screening are dwindling. Well-conceived confidential screening may be the only way to avoid strong-armed government intervention. The latter is certain to be divisive, and is likely to be counterproductive on balance.An efficacious vaccine remains remote, but an antiviral which prolongs life by at least several months in AIDS patients, but not all of them, is now available. Zidovudine (AZT), however, is toxic and mere prolongation of life without cure will impose an additional burden on AIDS economics.A novel virus (HIV-2) has been identified and is already widespread in West-Africans. It causes AIDS, but the present ratio of AIDS cases in those infected seems lower than with HIV(-l); this feature may be transient. HIV-2 antibodies are either detected or missed by anti-HIV-1 screens; if found, they can be distinguished from anti-HIV-1 only by special confirmatory technique. New screening assays showing equal sensitivity for HIV-1 and HIV-2 in a single test should be devised. At present, HIV-2 is very rare in Western countries compared to HIV-1.

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.

The aim was to determine the prevalence of HIV infection and risk factors for HIV infection in various population subgroups in Ethiopia. Serum panels from blood donors (n = 2610), from various population subgroups in Ethiopia were tested for anti-HIV-1/2 by ELISA. All ELISA repeatedly reactive samples were subjected for confirmation by immunoblot (IB) and anti-HIV-1 and anti-HIV-2 specific ELISAs. 155/2610 (5·9%) blood donors were HIV-1 infected. Of pregnant women, 84/797 (10·5%) were HIV-1 infected, and 1/797 (0·1%) was HIV-2 infected. 1/240 (0·4%) individuals from the rural population were HIV-1 infected. 198/480 (41·3%) female attendees, and 106/419 (25·3%) male attendees at sexual transmitted disease (STD) clinics were HIV-1 infected. One (0·2%) male, and 2 (0·4%) female STD patients were infected with both HIV-1 and HIV-2. It was concluded that the prevalence of HIV-1 infection varied from 0·4% among urban residents to 25·3–41·3% among STD attendees. There is a low prevalence of HIV-2 present in Ethiopian subjects. Risky sexual behaviour is significantly associated with HIV-infection in Ethiopia.

Blood donation is an essential step in transfusion medicine that must take into account the donor’s welfare, collection effectiveness, and blood product quality. This prospective study enrolled 13 canine blood donors, each subjected to both gravity and suction collection methods, in a randomized order. Clinical parameters, including heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), and rectal temperature (RT), were evaluated at four time points, including when the donor was on the floor and on the collection table, and before and after blood donation. The number of times the donor and needle required repositioning, the duration of the donation, the noise created by the apparatus, and the presence of a hematoma were evaluated. The weight, index of hemolysis, and hematocrit of each unit of blood were recorded. There was no significant difference between collection methods for either the clinical parameters at each time point or the prevalence of hematoma formation, the frequency of needle repositioning, the hemolysis index, or hematocrit. Collection by suction was noisier (P < 0.0001), faster (P = 0.004), and associated with significantly less donor repositioning (P = 0.007). Suction appears to be a safe and cost-effective method that should be considered to optimize blood donation.

Background: Blood transfusion is a life-saving method in emergencies. However, it also carries the risk of pathogen transmission, which is called transfusion transmitted infections (TTIs). All donated blood samples were screened for hepatitis B surface antigen (HBsAg), anti-hepatitis C virus antibody (anti-HCV), anti-human immunodeficiency virus antigens (anti-HIV½) and syphilis using Venereal Disease Research Laboratory (VDRL) test. This study was designed and carried out to determine the seroprevalences of TTIs among blood donors with different ABO and Rh blood groups. Identification of a relation between different blood groups and TTIs was anticipated. Methods: All blood donors data obtained from the Blood Center of Marmara University Pendik Training and Research Hospital between January 2013 and October 2018 are analyzed retrospectively. Serum samples were examined for HBsAg, anti-HCV, anti-HIV½, and VDRL. Results: HBsAg and anti-HIV½ positivity positivity rates were not statistically different according to ABO blood groups (p>0.05). Anti-HCV positivity rates are partially statistically significant (p<0.05). While the incidence of anti-HCV in patients with AB Rh (+) cases was significantly higher than that of 0 Rh (+), A Rh (+) and AB Rh (+) groups, no significant difference was found for the other analyzed blood groups (p>0.05). VDRL positivity rates did not differ significantly (p>0.05). Seropositive cases, as reported by Rh type blood group; HBsAg, anti-HCV, anti-HIV½, and VDRL positivity rates were not statistically significant (p>0.05). Conclusions: No significant relationship was found among TTIs and ABO and Rh type blood groups. For blood transfusion safety, screening tests should always and carefully be performed.

Abstract Background: In Turkey, prior to transfusion and apheresis, it is mandatory to screen blood for HBsAg, anti-HCV, anti-HIV 1/2, and syphilis. In recent years, efforts have been made to create effective diagnostic algorithms for screening, and as a screening strategy, many countries have switched from traditional algorithms to reverse algorithms. This study was carried out to evaluate the results we obtained after changing to chemiluminescence immunoassay (CLIA) based reverse algorithm, which is more sensitive and specific than the traditional algorithm and VDRL test we currently use for syphilis screening. Methods: The screening algorithm was initiated with the treponemal CLIA method. The reactive samples were tested using a nontreponemal test VDRL and a second treponemal test TPHA. In the descriptive analyses, the averages, numbers, and percentage distributions were calculated. The group comparisons were undertaken with the chi-square test, accepting p < 0.05 as statistically significant. Results: Of the 5,053 samples that were tested with CLIA syphilis TPA assay 5,043 were negative (99.802%) and 10 were positive reactive (0.198%), and the difference between the two was statistically significant (p < 0.001). Ten samples that were recurrently reactive were analyzed by VDRL and TPHA tests simultaneously. VDRL was negative in all 10 samples, whereas TPHA was negative in one sample, but positive in nine samples at a titer of ≥1/160. Conclusion: Based on the results of this study, we decided to use the CLIA method and reverse algorithm instead of using the traditional algorithm and VDRL as the initial screening method.

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.
