Seroprevalence of Transfusion-Transmissible Infections among Family Replacement Donors and Voluntary Non-Remunerated Blood Donors During the COVID-19 Pandemic in Sub Saharan Africa. Mediterr J Hematol Infect Dis 2024; 16:e2024008. [PMID: 38223484 PMCID: PMC10786141 DOI: 10.4084/mjhid.2024.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 12/10/2023] [Indexed: 01/16/2024] Open
Abstract
Introduction : According to WHO, regular, voluntary, unpaid blood donors are the safest group of donors, as they have the lowest prevalence of blood transmitted infections. However, family/replacement blood donors is widely used in sub Saharan Africa and this practice was exacerbated during the COVID 19 pandemic. This study aimed to compare the seroprevalence of infectious markers in family replacement blood donors and voluntary non-remunerated blood donors during the COVID 19 pandemic in a country of sub Saharan Africa.
Materials and Methods
Blood donors received at the National Centre of Blood Transfusion (NBTC) of Dakar from August 1st to October 31th 2021, were included in this study. All donors completed a pre-donation questionnaire. Donors identity, epidemiological parameters, reasons for donation and laboratory results were collected in the Inlog® software of the NBTC. The serological tests for HBV, HIV and HCV were performed with chemiluminescence technology. The Rapid Plasma Reagent test was used to find out treponemal antibodies. The determination of ABO and Rh blood groups was performed using monoclonal antisera following classical hemagglutination test on a plate.
Results
A total of 5002 donors were collected during this COVID-19 pandemic period. Blood family/replacement donors represented 54.0% and new voluntary donors represented 52.6%. Comparison of HIV, HCV and syphilis markers seroprevalence showed no statistically significant difference between new voluntary donors and new family replacement donors (p>0.05). However, for HBV the seroprevalence was significantly higher in new family replacement donors (p=0,002).
Conclusion
The proper supply of blood was impacted by the COVID-19 pandemic meanwhile replacement donations had contributed to limiting the damage observed with blood shortages. However, the significant differences noted on the seroprevalences of transfusion-transmissible infections between voluntary non-paid donors and family/replacement donors strengthens WHO recommendations for the selection of volunteer non-paid donors to lower transfusion-transmissible HBV in sub Saharan Africa.

Abstract
Introduction Blood-borne pathogens such as human immunodeficiency virus (HIV), hepatitis B and C (HBV and HCV) viruses and Treponema pallidum remain a major public health problem in sub-Saharan Africa. The purpose of this study was to assess the frequency and clinical implications of HIV, HBV, HCV and Treponema pallidum markers in blood donors in a rural area of Southeast Gabon (Koula-Moutou) from 2012 to 2017. Methods Hepatitis B surface antigen (HBsAg), anti-HIV, anti-HCV and anti-Treponema pallidum antibodies were screened using rapid diagnostic tests (RDTs). Results Of a total of 5,706 blood donors, 1,054 (18.5%) were seropositive for at least one infectious marker and 59 (5.6%) had serologic evidence of multiple infections. The overall seroprevalence of HIV, HBsAg, HCV, and syphilis was 3.1%; 5.9%; 6.2% and 3.3%, respectively. HIV, syphilis and HCV distributions were associated with neither the sex nor the age of the donors. Only HBsAg seroprevalence was significantly higher in donors of the age group 26-35 years old compared to donors of the age group 36-45 years (OR = 1.43 (95% CI: 1.01-2.04), P = 0.045). There was a significant increase in the frequencies of HIV and syphilis and a regression of HBsAg and HCV among blood donors. Conclusion This study presents the epidemiology of the main pathogens detected in blood donors in a rural area in Gabon. We found that the overall distribution of transfusion transmitted infectious diseases were lower than those observed in the general population but could be underestimated due to the use of RDTs in the screening process of the blood donations.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of hepatitis B surface antigen (HBsAg) among febrile individuals tested at Mercy Hospital Research Laboratory (MHRL) in Bo, Sierra Leone. RESULTS A total of 860 febrile individuals ages 5 years and older were tested by MHRL between July 2012 and June 2013 with a Standard Diagnostics Bioline HBsAg rapid diagnostic test. The overall HBsAg prevalence rate was 13.7%, including a rate of 15.5% among males and 12.6% among females. The HBsAg rate did not differ by child or adult age group (p > 0.5). The prevalence rate in Bo was similar to the 11-15% HBsAg prevalence rates reported in the past decade from other studies across West Africa. Scaling up the infant hepatitis B vaccination program in Sierra Leone will be important for reducing the future burden of disease and premature death attributable to chronic viral hepatitis B disease.

Abstract
STUDY OBJECTIVES The screening of anti-Human Immunodeficiency Virus antibodies is mandatory in every blood donor admitted to the Blood Bank of Kinshasa University Clinics since 1984. However, no compiled data are available to date. The objective of this study was to establish the trend, prevalence, viral co-infections, and determinants of Human Immunodeficiency anti-Virus serology in blood donors admitted between 2003-2006 and 2008-2013. PATIENTS AND METHODS A retrospective analysis was carried out at University Kinshasa Clinics, using blood donors' records during 2003-2006 and 2008-2013. The prevalence of the human immunodeficiency virus per year, age, sex and type of blood donors were estimated. Independent predictors of human immunodeficiency virus seropositivity were also identified. RESULTS Out of 26,341 blood donors, 2.2% (n=576/26,341) were seropositive for Human Immunodeficiency Virus. Age<25 years (OR=1.7; 95% CI: 1.4-2; P<0.0001) and Hepatitis C virus seropositivity (OR=3; 95% CI; 1.8-4.9; P<0.001) emerged as independent predictors of Human Immunodeficiency Virus seropositivity. CONCLUSION This study shows a strong association between the Human Immunodeficiency Virus and hepatitis C and younger age respectively. Further studies are needed to ensure safety of Blood donation in Democratic Republic of Congo.

Abstract
Introduction To estimating the seroprevalence of HIV, hepatitis B, hepatitis C and syphilis among blood donors in the Aïoun hospital. Methods This is a retrospective study from 1 January 2010 to 31 December 2015. Results On the five-year study period, 1,123 donors were collected. Of these, 182 were HIV-positive, an overall prevalence of 16.2% with predominance in male with a sex ratio Man/Woman of 5.2. The average age of donors was 32.7 ± 10 years (range 17-73 years). The most represented that age group 21-30 years (40.5%). The seroprevalence found were 1.2% for HIV, 11.8% for HBV, HCV 0.2% and 3% for syphilis. Co-infection was found in 0.7% of which 0.5% of dual HIV HBV/Syphilis and 0.2% in HBV/HIV. Conclusion The transmission of infectious agents related to transfusion represents the greatest threat to transfusion safety of the recipient. Therefore, a rigorous selection and screening of blood donors are highly recommended to ensure blood safety for the recipient.

Abstract
OBJECTIVES In Niger, 65% of hepatocarcinoma and 75% of cirrhosis cases were due to hepatitis B virus (HBV). We studied the genotypic characteristics of HBsAg in chronically HBV-infected patients in Niamey. METHODS We studied prospectively HBV genotypic patterns among hospitalized patients with HBV infection in the National Hospital of Niamey, Niger. Patients were screened for hepatitis B surface antigen (HBsAg) and HBV genotyping was performed on the HBsAg-positive patients. RESULTS In this study, we have confirmed the predominance of the HBV genotype E (HBV-E) in Niger and have identified 2 recombinant forms including HBV-E/D and HBV-A3/E reported previously among blood donors in Niger and Ghana, respectively. Amino acid substitutions found in HBV sequences obtained here included P120T, S143L, G145A and A194T. These substitutions were characterized as being associated with modified antigenicity and, notably, with impaired serological detection of HBsAg, while the A194T variant was found to have a controversial role in reduced susceptibility to tenofovir. CONCLUSIONS We have identified two recombinant HBV forms and rare genotypic patterns in Niger that may affect hepatitis B surface antigen antigenicity, and improve current knowledge of epidemiological, clinical and virological patterns of hepatitis B in this country.

Abstract
OBJECTIVES Prevention of blood transfusion-transmitted infections includes blood donor screening and effective infectious markers screening for donated blood. This study had two main objectives: to determine seroprevalence of HBV, HCV, HIV and syphilis in blood donors of the Yaoundé Central Hospital and to study sociodemographic factors of blood donors. PATIENTS AND METHODS A retrospective study of consecutive blood donors' records from January to December 2013 was conducted. Seroprevalence of hepatitis B, hepatitis C, human immunodeficiency viruses and syphilis were determined in 9024 whole blood donations collected in the Yaoundé Central Hospital in the centre region, Cameroon using Elisa kits. RESULTS Mean age of donors was 28 years. The male to female ratio was 14.8. Most of blood donors were replacement donors (97.2%) and first-time donors (76.8%). Up to 19.3% of the donors tested positive for at least one infectious agent, in which 0.1% presented a positive test for three viruses (HIV, HCV and HBV). The overall seroprevalence in blood donors was 12.6% for HBsAg, 3.2% for hepatitis C antibody, 3.3% for HIV-1/2 antibodies and 0.2% for syphilis. The prevalence of HBsAg was significantly higher in men (P=0.001), among first-time donors (P=0.003), in blood group A (P=0.01) and those with the rhesus positive blood (P=0.01). The prevalence of anti-HCV was significantly higher among first-time donors (P=0.05). The prevalence of anti-HIV was significantly higher in first-time donors (3.7% vs 2.2%, P=0.02). CONCLUSION First-time blood donors and replacement donors are the two types of donors in Cameroon. Replacement donors are considered as having a major risk of transmission of infections to recipients. The seroprevalence of HIV, HBV, HCV, and syphilis among these donors is high and reflects how much these agents are present in Cameroon. Effective infectious markers screening and organization of blood donors into an association of volunteer's donors are necessary to secure blood transfusion in Cameroon.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of medical screening to retain blood donors in window period by comparing the seroprevalence of infectious agents (HIV, hepatitis B and C, syphilis) in deferred versus accepted blood donors. MATERIALS AND METHODS This prospective and transversal study was performed during 4 months in the National Blood Transfusion Center in Dakar (Senegal). We conducted a convenience sampling comparing the seroprevalence of infectious agents (HIV, HBsAg, HCV and syphilis) in deferred versus accepted blood donors after medical selection. RESULTS In total, 8219 blood donors were included. Medical selection had authorized 8048 donors (97.92%) and deferred donors were 171 (2.08%). The prevalence of HIV was higher in the deferred than in accepted blood donors (1.75% vs. 0.05%) (P=0.0003; OR=35.91), as well as for HBsAg (12.87% vs. 7.35%) (P=0.006; OR=1.86). HCV antibodies were present in 0.71% of accepted blood donors and 0.58% in deferred blood donors (P=0.65; OR=0.82). Only accepted donors had brought the infection of syphilis (0.34%) (P=0.56; OR=0). CONCLUSION Medical selection is efficient to exclude blood donors at high risk of HIV transmission and to a lesser extent of HBV. However, current medical screening procedures do not allow us to exclude donors asymptomatic carriers of HCV and syphilis.
