Abstract
Background Ensuring blood safety is the primary goal of transfusion medicine. Despite extensive serological tests and strict safety measures, the risk of transfusion-transmitted infections (TTIs) still exists. As applied to blood screening, Nucleic Acid Amplification Test (NAT) offers much higher sensitivity for detecting viral infections. It is, however, currently available to a handful of centers due to the high cost. This study aims to establish the Effectiveness of NAT by assessing the NAT yield and residual risk of transmission of Hepatitis B virus (HBV), hepatitis C virus (HCV) and HIV with and without NAT testing. Material and method This prospective cross-sectional study recruited blood donors from January 2020 to November 2022. All donors underwent routine serologic screening. Only serologically negative donors were tested for HBV, HCV, and HIV by NAT. The NAT yield and residual risk (RR) per million donors were computed for viral infections in seronegative blood donors and calculated using the incidence/window period model. Result A total of 59708 donors were included during the study period. The overall prevalence of TTI's were: For HCV 1.7% (n = 1018), HBV 1.5% (n = 918), HIV 0.07% (n = 47), Syphilis 1.2% (n = 758) and malaria 0.3% (n = 218). Out of 57759 seronegative donors, thirty-four NAT-reactive samples were identified, with 3 cases of HCV, 31 cases of HBV, and Nil HIV cases. NAT yield of HBV was 1 in 1863 with an RR of 8.6 per million, followed by HCV with a NAT yield of 1 in 19253 and RR of 0.8 per million donations. NAT testing reduced RR for HBV by 48.9% and HCV by 94.5%. Conclusion Our study showed that NAT detected 34 out of 57759 cases initially missed by serological tests. The study suggests that the parallel use of serology and NAT screening of donated blood would be beneficial.

Abstract
Background Transmissible Infections (TTI's) are a cause of significant burden on health care facilities by imposing a threat of infection transmission through disease reservoirs in asymptomatic donors. This eventually leads to a serious challenge in acquiring blood bags in a country like Pakistan where transfusion dependent disease are of high prevalence. The objective of this study is to determine the seroprevalence of TTI's in blood donors in Rawalpindi District through a multi-center approach. Materials and Methods This is an observational descriptive retrospective study based on 6 transfusion centers in the Rawalpindi District. The time frame of the study was from January 2015 to December 2018. A total of 223,242 donors were consecutively included and data on donor type, the purpose of transfusion, and seroprevalence (HBV, HCV, HIV, Syphilis, and Malaria) were collected through a structured questionnaire and laboratory investigation results. The collected data were entered in SPSS version 21.0 for analysis. Results The seroprevalence of blood borne infections was 7,897 (3.537%) of which HBV, HCV, HIV, Syphilis and Malaria accounted for 2410 (1.080%), 3105(1.391%), 0(0.000%), 2017 (0.933%) and 365 (0.171%), respectively. Reactive samples reduced from 4.850% to 3.537% over 4 years, while there was a rise of 37.478% of blood donors from 2015 to 2018. The total number of voluntary donors and replacement donors was 22079 (9.890%) and 201156 (90.107%), with a rising incidence in voluntary donors from 2015 to 2018. A considerable number of donor bags were transfused to Thalassemia, Anemia, Leukemia and Hemophilia patients, 28156 (12.612%). This number also showed increasing rates from 11.654% to 14.017%. Conclusion In conclusion, our study suggests that the risk of transmission through transfusion is still considerable. Targeting donors with a low-risk profile, a screening questionnaire, an ample supply of quality screening tests, and awareness campaigns for the diseases in question must be carried to further decrease the risk of transmission of TTIs in Pakistan.

Abstract
Introduction
Blood transfusion is linked to several risks, most notably the transmission of transfusion-transmitted infections (TTIs), including hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), syphilis, and malaria. The risk posed by these blood-borne infectious agents is high in developing countries, including Pakistan. This fact stresses the need for regular surveillance of TTIs. Therefore, the present study was undertaken to assess the seroprevalence of TTIs at a regional blood center.
Material and Methods
This was a retrospective 4-year descriptive study undertaken at the Regional Blood Centre in Peshawar, Khyber Pakhtunkhwa Province of Pakistan, on the blood donor data from June 2016 to May 2020. A total of 41,817 donors donated blood during the study period and were screened for HBV, HCV, HIV, syphilis, and malaria. To ensure donor privacy, donors were identified via codes and no personal information was available. The data were extracted from the ZAAVIA blood transfusion information system database.
Results
The study included a total of 41,817 donors—41,493 (99.22%) males and 324 (0.78%) females. Of them, 22,343 (53.43%) were voluntary donors while 19,474 (46.57%) were replacement donors. An overall TTI prevalence rate of 4.61% was found. The TTI prevalence rate in voluntary donors was 3.90% while 5.42% in replacement donors. The overall prevalence of HBV, HCV, HIV, syphilis, and malaria was 1.95, 1.38, 0.23, 0.91, and 0.14%, respectively.
Conclusion
The current study documented a high prevalence (1,929 out of 41,817, 4.61%) of TTIs, especially in replacement donors (1,057 out of 19,474, 5.42%), and low participation of female donors. The recommendations include the promotion of voluntary blood donors, enrolment of female blood donors, and screening of donated blood through highly sensitive screening assay (i.e., nucleic acid testing).

Abstract
PURPOSE There were approximately 37.9 million persons infected with HIV in 2018 globally, resulting in 770,000 deaths annually. Over 50% of this infection and deaths occur in sub-Saharan Africa, with countries like Nigeria being seriously affected. Nigeria has one of the highest rates of new infections globally. To control HIV infection in Nigeria, there is a need to continually screen high-risk groups for early HIV infection and subtypes using very sensitive methods. In this study, new HIV-1 infection and circulating HIV-1 subtypes among febrile persons and blood donors were determined. Performance characteristics of three commercial EIA kits were also evaluated. METHODS In total, 1028 participants were recruited for the study. New HIV-1 infection and subtypes were determined using enzyme immunoassays and molecular techniques, respectively. Sensitivity, specificity, predictive values, and agreements were compared among the EIA kits using PCR-confirmed HIV-positive and negative samples. RESULTS The overall prevalence of HIV infection in this study was 5.35%. The rate of new HIV infection was significantly different (p < .03674) among 1028 febrile persons (Ibadan: 2.22%; Saki: 1.36%) and blood donors (5.07%) studied. Three subtypes, CRF02_AG, A, and G, were found among those with new HIV infection. Whereas the commercial ELISA kits had very high specificities (94.12%, 100%, and 100%) for HIV-1 detection, Alere Determine HIV-1 antibody rapid kit had the lowest sensitivity score (50%). CONCLUSION Genetic diversity of HIV-1 strains among infected individuals in Oyo State, Nigeria, is still relatively high. This high level of diversity of HIV-1 strains may impact the reliability of diagnosis of the virus in Nigeria and other African countries where many of the virus strains co-circulate.

Abstract
Transfusion transmitted infections have remained a major deterrent to public health, particularly among the patients with transfusion-dependent Beta thalassemia in developing countries. Although proper donor selection through adoption of WHO-advised infection panel has lowered the rate of infections, the multi-transfused patients are not free of risk. In this study, we screened 148 transfusion-dependent Beta thalassemia patients to determine the frequency of Hepatitis C Virus (HCV), Hepatitis B Virus (HBV) and Human Immunodeficiency Virus (HIV) using the ELISA method. Among them, infected cases with HCV, HBV and HIV were 13.51%, 3.37% and 0%, respectively. Moreover, 2% of the patients were found to be co-infected with both HBV and HCV. The percentage of infections in the patients with frequent transfusion interval (≤30 days) was significantly higher (p < 0.0005) than that in the patients with less frequent transfusion intervals (>30 days). Immunochromatography (ICT)-based rapid test kits are usually used to screen and confirm these infections in the blood of the patients. However, ICT-based tests are not sensitive enough to detect the infections. So, a combination of both Nucleic Acid testing (NAT) and serological testing are suggested to significantly reduce the risk of viral infections during blood transfusion.

A Systematic Review of Transfusion-Transmissible Infections Among Blood Donors and Associated Safety Challenges in Pakistan. J Blood Med 2020; 11:405-420. [PMID: 33173367 PMCID: PMC7646486 DOI: 10.2147/jbm.s277541] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 10/15/2020] [Indexed: 01/08/2023] Open
Abstract
The blood transfusion (BT) system in Pakistan is fragmented, demand-driven and depends on weakly regulated transfusion practices. There is a considerable possibility that transfusion-transmissible infections (TTIs) are contributing to the current epidemic of hepatitis B virus (HBV) and hepatitis C virus (HCV) (affecting 7.4% of the general population) in the country. To study this issue, we conducted a systematic review to identify articles related to TTIs and transfusion safety in Pakistan from January 1, 2010 to January 31, 2020. A review of 33 articles met the final criteria for qualitative synthesis. Analysis of these studies showed a cumulative frequency of HBV 2.04%, HCV 2.44%, HIV 0.038%, syphilis 1.1% and malaria 0.11%. The frequency of coinfections among blood donors varied from 0.0099% to 0.35%. The highest number of coinfections were HCV and syphilis, followed by HCV and HBV infections. Syphilis and malaria were tested in only 38% and 46% of all the blood donations in one study. The rate of voluntary non-remunerated donations (VNRDs) was less than 13%, and male donors were 95% to 100% in these studies. There was a significant difference in the frequency of HBV and HCV in VNRDs (0.48%) as compared to replacement donors (RDs) (4.15%). In short, this review shows a high frequency of TTIs, especially HBV, HCV and syphilis in the blood donor population in Pakistan. There is a high dependency on RDs, minimal use of healthy voluntary blood donation practices, inadequate screening of high-risk donors, repeated collections of the blood from RDs, poor quality of screening methods and limited knowledge of donor health. Without standardized safe transfusion practices, there will be an ongoing increase in transmission of TTIs, especially HBV, HCV, syphilis, and HIV leading to a significant adverse public health impact.

SAGE Open Med 2020; 8:2050312120936930. [PMID: 32647577 PMCID: PMC7328218 DOI: 10.1177/2050312120936930] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Accepted: 05/29/2020] [Indexed: 11/17/2022] Open
Abstract
Background: Blood transfusion is an intervention used to save life particularly for those
patients who survive only with receiving blood. Establishing effective
diagnostic test menus concerning the screening of transfusion-transmissible
infections in the blood banks play a vital role to safeguard recipients from
transfusion-transmissible infections. Objective: The aim of this study was to assess blood transfusion-transmissible malaria
and its screening cost analysis in Hawassa regional blood bank, Hawassa,
Sothern Ethiopia. Methods: An institutional-based cross-sectional study was conducted from April to May
2018 among 414 voluntary blood donors. Each participant’s blood sample was
screened for most transfusion-transmissible infections using
antigen/antibody tests, while rapid diagnostic test and microscopy were used
for malaria screening and confirmation. In addition, the cost screening of
transfusion-transmissible infections was calculated using activity-based
costing method. Results: The overall seropositivity of transfusion-transmissible infections was 7.0%
and the positivity rate of hepatitis B virus, syphilis, and
Plasmodium falciparum was 5.6%, 1.0%, and 0.5%,
respectively. The cost per test of each transfusion-transmissible infection
was US$5.04 for human immunodeficiency virus, US$4.61 for hepatitis B virus,
US$5.11 for hepatitis C virus, and US$4.75 for syphilis, while the cost per
test of malaria rapid diagnostic test was US$4.74 and this is comparatively
lower than the cost per test of other transfusion-transmissible infections
except for hepatitis B virus. In addition, total cost of laboratory incurred
for transfusion-transmissible infections screening is estimated to be
US$213,634.5 per year, while it becomes US$265,537.5 if the malaria
screening cost is added. This means 19.54% of the total cost of laboratory
incurred per year or US$51,903. Conclusion: The positivity rate of malaria parasites among voluntary blood donors was
0.5%, and it might be increased if the study was conducted in high
transmission seasons. A cost of malaria screening is comparatively lower
than costs of other transfusion-transmissible infections except for
hepatitis B virus. Therefore, the screening of malaria parasites should be
considered as one of the test menus of transfusion-transmissible infections
in blood banks, especially in malaria-endemic areas.
