Background: HIV and Hepatitis B infections are public health problems in Nepal. This study was conducted based at NRCS/CBTS, with the objective of determining the HIV and HBsAg sero-prevalence in non-remunerated volunteer blood donors. Materials and Methods: A total of 66,904 units of blood collected, following donor recruitment criteriaduring March 2009-Sept. 2010 was included for analysis. All donated blood samples were subjected to screening for Transfusion transmitted infections including HIV and Hepatitis B surface antigen using standard ELISA test kits (Dade Behring, Germany). Initial reactive sera were re-tested for reconfi rmation with same test kits plus another test kit (Detect-HIV, Adaltis Inc, and Qualisa). Results: Out of 66,904 units of blood collected, 56,973 units were from male and 9,931 were from female donors. Among the total screened samples, 73 (0.10%) were found to be positive for HIV, {0.11% (64/56973) in male and 0.09% (9/9931) in female}; the difference between male and female donors (?2<3.841) was statistically signifi cant. The seroprevalence of HIV was highest in age group of 30- 39 both in male and female (p<0.001). Similarly, for HBsAg, overall seroprevalence was found to be 0.47% (316/66904 {0.42% (242/56973) in male and 0.74% (74/9931) in female}. The difference was statistically signifi cant (?2<3.841). The highest HBsAg sero-prevalence(0.65%) was also observed in same age group i.e. 30-39 (p<0.001) in male but highest seroprevalence (2.63%) was observed inage group of ?50 in female. Conclusion: Both HIV and HBV sero-prevalence is high in adult voluntary blood donors. Journal of Pathology of Nepal (2013) Vol. 3, No.1, Issue 5, 390-393 DOI: http://dx.doi.org/10.3126/jpn.v3i5.7864

Hepatitis B and Hepatitis C are the chronic viral infection that might be transmitted by blood transfusion. Nepal is known to have lowest seroprevalence in Asia. The main objective of the present study is to find out the prevalence of hepatitis B and Hepatitis C and their co-infection among blood donors during study period from March to August 2014. This was a cross sectional study among volunteer blood donors in Dharan who had donated the Blood. A total of 4930 donated blood samples were collected and screened for hepatitis B and hepatitis C by using a rapid enzyme immunoassay (EIA) technique. Among 4930 blood samples under study, the overall seroprevalence of hepatitis B were 0.22% (11 out of 4930) and hepatitis C were 0.39% (19 out of 4930) (P value = 0.01) and the prevalence being lower in females than males for both cases. Hepatitis B were more in age group of 21 -30 (0.4%) but hepatitis C in age group of 31-40 (0.5%). Hepatitis B and C are potential threats to be transmitted from unscreened blood.Sunsari Technical College Journal 2015, 2(1):13-16

Viral hepatitis and malaria, both are the diseases with noticeable disease burden in Nepal. Malaria is seasonal with high disease burden during post rainy season. Severe malaria also shows similar symptoms to viral hepatitis. This is collaborative study has been conducted during June - September 2006 with the objective of determining the prevalence of hepatitis B and malaria in Nepalese blood donors to find out the need of routine malaria testing in each pint of donated blood. During the study period, screening of malaria and hepatitis B surface antigen (HBsAg) were done in 1200 blood samples collected from blood donors at Kathmandu, Nepalgunj and Biratnagar Blood Banks. Malaria diagnosis was done using one drop of blood from each unit of blood using Giemsa stained thick and thin smear microscopy, while hepatitis B surface antigen (HBsAg) was detected using commercial ELISA. Of the total 1200 blood samples analyzed, 600 were collected at Kathmandu and 300 each at Nepalgunj and Biratnagar blood banks, situated in malaria endemic southern districts. Among the total 1200 samples, 1% (12) of the sample was found reactive for HBsAg; while only 0.33 % (4) samples were positive for malarial parasite. 1.33% (8) samples from Kathmandu and 1.33% (4) samples from Nepalgunj were positive for HBV. 1% (3) samples from Nepalgunj and 0.33% (1) sample from Biratnagar were found to be positive for malarial parasite. None of the samples from Biratnagar were positive for HBsAg, while none of the samples from Kathmandu were positive for malarial parasite. All of the malaria cases were due to Plasmodium vivax. All the infected cases were male. Co-infection of malaria and HBV was not observed during the entire period of study. However more extensive study is needed in other endemic areas of Nepal, the study indicated that the continuation of screening each point of donated blood for Hepatitis B, while screening of malarial parasites in donors of endemic terai districts may be useful in preventing transmission of malaria through transfusion.

Background: The knowledge of the incidence of blood Transfusion Transmissible Infections (TTIs) such as Hepatitis B, Hepatitis C, Human Immunodeficiency Virus infection, malaria and syphilis is essential for monitoring the safety of blood supply. Objective: To describe the prevalence of TTIs for monitoring blood supply safety and evaluating the efficacy of screening procedures. Methods: A five-year retrospective study spanning January 2016 to December 2020 was carried out on voluntary blood donors at blood donation camps organised by Adesh Medical College and Hospital, Kurukshetra, Haryana, India, and from donors at the hospital’s blood bank. The donated blood was tested for Hepatitis-B, Hepatitis-C, Human Immunodeficiency Virus (HIV), malaria and syphilis. Results: There were a total of 10,468 voluntary blood donors during the period of study. Out of all the donors, 0.4% tested positive for at least one of the TTIs, including 0.06% testing positive for HIV, 0.21% for Hepatitis-B virus (HBV) infection (Hepatitis-B Surface Antigen) and 0.13% for Hepatitis-C virus (HCV) infection (Anti HCV Antibodies). None of the voluntary donors was positive for malaria or syphilis. There were no co-infections. Conclusions: The prevalence of TTIs among voluntary blood donors was low hence the advocation for blood from this group of donors. Donated blood specimens should be more effectively screened, and blood should be rationally used.

World Health Organization (WHO) classified Nigeria as a hyper-endemic hepatitis B surface antigen (HBsAg) positive nation with prevalence ≥ 8%. This study intends to add information that could strengthen established database to improve awareness and prevention of hepatitis B virus (HBV) infection. We aimed to evaluate seroprevalence and trend of HBsAg among blood donors in Olabisi Onabanjo University Teaching Hospital (OOUTH), Sagamu, Ogun State, Nigeria over a five-year period. Data from records of 7,102 individuals aged ≥ 20 years old who donated blood to blood bank in this hospital from January 2012 to December 2016 were analysed for gender, age, number of donors per year and HBsAg status. Data analysis was done with Statistical Package for Social Sciences software. P ≤ 0.05 was considered statistically significant. Males were in the majority (6,547 [92.2%]). Age 30–39 years old was the major group (3,052 [43.0%]). Pooled HBsAg seroprevalence was 486 (6.8%). Females had the highest HBsAg seroprevalence across board with highest rate of 10 (19.6%) in year 2012 and pooled prevalence of 73 (13.2%). Age group of ≥ 50 years old had highest HBsAg seroprevalence 39 (8.5%) while age group of 20–29 years old had least 128 (5.8%). Stratified HBsAg positivity decreased steadily from year 2012 to year 2016. This location was HBV intermediate-endemic. There were age, gender and yearly seroprevalence of HBsAg related trends which could be leveraged upon in finding effective preventive measures against the disease. We recommend mass vaccination by government against HBV infection in addition to provision of sensitive blood investigational equipment.

INTRODUCTION: India being the second highly populated nation in the world. HIV/AIDS has acquired pandemic proportion in the world. Estimate by WHO for current infection rate in Asia. India has the third largest HIV epidemic in the world. HIV prevalence in the age group 15-49 yrs was an estimate of 0.2%. India has been classified as an intermediate in the Hepatitis B Virus (HBV) endemic (HBsAg carriage 2-7%) zone with the second largest global pool of chronic HBV infections. Safety assessment of the blood supply, the quality of screening measures and the risk of transfusion transmitted infectious diseases (TTIs) in any country can be estimated by scrutinizing the files of blood donors. After the introduction of the blood banks and improved storage facilities, it became more extensively used. Blood is one of the major sources of TTIs like hepatitis B, hepatitis C, HIV, syphilis, and many other blood borne diseases. Disclosure of these threats brought a dramatic change in attitude of physicians and patients about blood transfusion. The objective of this study is to determine the seroprevalence of transfusion transmitted infections amidst voluntary blood donors at a rural tertiary healthcare teaching hospital in Chhattisgarh. MATERIAL AND METHODS: This retrospective study was carried out in Chandulal Chandrakar Memorial Medical College, Kachandur, Durg. Blood donors were volunteers, or and commercial donors who donated the blood and paid by patients, their families, or friends to replace blood used or expected to be used for patients from the blood bank of the hospital. After proper donation of blood routine screening of blood was carried out according to standard protocol. Laboratory diagnosis of HIV 1 and HIV 2 was carried out by ELISA test. Hepatitis B surface antigen was screened by using ELISA. RESULTS: A total of 1915 consecutive blood donors’ sera were screened at Chandulal Chandrakar Memorial Medical College, blood bank during study period. Of these 1914 were male and 1 female. The mean age of patients was found to be 29.34 years with standard deviation (SD) of 11.65 Years. Among all blood donors in present study, 759(39.63%) were first time donors and 1156(60.37%) were repeated donors. 1 patient was HIV positive in first donation group while 3 (75%) were positive in repeat donation group. 7 (38.9%) were HBsAg positive in in first donation group while 11(61.1%) were positive in repeat donation group. Two patients in first donation group had dual infection of HIV and HBsAg. CONCLUSION: Seropositivity was high in repeated donors as compared to first time donors. The incidence of HIV is observed to be 0.2% and that of HBsAg is 0.94%. Strict selection of blood donors should be done to avoid transfusion-transmissible infections during the window period.

Abstract Background Hepatitis B virus (HBV) infection is a major concern for blood safety in high-prevalence HBV countries such as China. In Shenzhen, dual hepatitis B surface antigen (HBsAg) enzyme-linked immunosorbent assays (ELISAs) have been adopted in parallel with nucleic acid testing (NAT) for donors for over a decade. A small proportion of blood donors test reactive (R) for HBsAg but negative through routine NAT, which can lead to HBV infection with an extremely low viral load. Objectives We aimed to investigate and analyze the molecular characteristics of HBV among blood donors that tested HBsAg R in a single ELISA test. Methods Blood donations were evaluated in this study if confirmed HBsAg R through one of two ELISA kits. Samples with non-reactive (NR) results by NAT were collected and tested for HBsAg by chemiluminescent microparticle immunoassay (CLIA) with a neutralization test. The level of HBsAg was further assessed by electrochemiluminescence immunoassay (ECLIA). The viral basic core promoter (BCP) and pre-core (PC) and S regions were amplified by nested PCR. Quantitative real-time PCR (qPCR) for viral load determination and individual donation (ID)-NAT were adopted simultaneously. HBsAg was confirmed with CLIA, ECLIA, nested PCR, qPCR, and ID-NAT. Results Of the 100,252 donations, 38 and 41 were identified as HBsAg R with Wantai and DiaSorin ELISA kits, respectively. Seventy-nine (0.077%, 79/100,252) blood samples with ELISA R-NR and NAT NR results were enrolled in the study. Of these, 17 (21.5%,17/79) were confirmed as HBsAg-positive. Of the 14 genotyped cases, 78.6% (11/14) were genotype B, and C and D were observed in two and one sample, respectively. Mutations were found in the S gene, including Y100C, Y103I, G145R, and L175S, which can affect the detection of HBsAg. A high-frequency mutation, T1719G (93.3%), was detected in the BCP/PC region, which reduced the viral replication. Conclusion A small number of blood samples with HBsAg ELISA R-NR and NAT NR results were confirmed as HBV infection, viral nucleic acids were found in most of the samples through routine NAT methods. It is necessary to employ more sensitive and specific assays for the detection of HBV infection among blood donors.

Abstract Objective Hepatitis B surface antigen (HBsAg) is known as the hallmark of hepatitis B virus (HBV) infection. This study aimed to determine whether an HBsAg neutralization test is necessary to accurately interpret HBsAg test results. Methods Initially reactive HBsAg specimens from a 5-year period, with cutoff index values between 1.0 and 2.0, were subjected to neutralization confirmatory testing using an Elecsys HBsAg Confirmatory test kit (Roche Diagnostics GmbH. Mannheim, Germany). Results The neutralization test showed 46.1% positive (confirmed positive group) and 53.9% negative (confirmed negative group) results from the total specimens. Among the confirmed negative group, 79.5% of patients were confirmed to be negative for the current infection, whereas 4 patients in the chronic hepatitis B subgroup showed a neutralization percentage close to 40%. More than half of patients in the confirmed positive group were considered to be in the hepatitis B e antigen-negative inactive HBsAg carrier phase. Conclusion In populations with intermediate HBV prevalence, a neutralization test is necessary to confirm an HBsAg result and reduce the false positive and false negative rates of initial HBsAg tests.
