Seroprevalence of HBV, HCV and HIV-1 and Correlation with Molecular Markers among Multi-Transfused Thalassemia Patients in Western India. Mediterr J Hematol Infect Dis 2020; 12:e2020038. [PMID: 32670516 PMCID: PMC7340250 DOI: 10.4084/mjhid.2020.038] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Accepted: 06/06/2020] [Indexed: 12/27/2022] Open
Abstract
Background Multitransfused β-thalassemia major patients are always at high risk of having Transfusion Transmitted Infections (TTIs). This study was aimed to determine the seroprevalence of HBsAg, Anti-HIV-1/2, and Anti-HCV among these patients and to correlate the same with NAT testing. Methods A total of 196 patients with β-thalassemia were included in the study. Patients were screened for the presence of viral markers by third-generation ELISA test as well as for viral DNA/RNA by NAT test. Results Among 196 multi-transfused Beta-thalassemia patients, the seroprevalence of anti-HCV was very high 100 (51.1%), however, anti-HIV1/2 was 6 (3.1%), and HBsAg were 3 (1.5%). Surprisingly similar patterns were observed in the prevalence of molecular markers, as HCV-RNA were 66 (33.7%) of the patients along with HIV-1 RNA were 8 (4.1%), and HBV-DNA were 5 (2.5%) patients. Overall eight (4.1%) patients were found to have coinfections, where two were positive for HBsAg/anti-HCV by ELISA along with 3 (1.5%) were positive for HBV-DNA/ HCV-RNA, 1 (0.5%) was positive for HIV-RNA/HBV-DNA, and 2 (1%) had coinfection of HIV-RNA/ HCV RNA by NAT testing Conclusion The prevalence of HCV infection among multi-transfused β-thalassemia patients is significantly higher than that of the HBV and HIV infections. This scenario should be controlled and monitored by doing regular follow-up testing schedules of such patients and also the administration of the booster dose of the HBV vaccine along with HCV treatment with antiviral DAAs.

Abstract
Timely, affordable access to screened blood is essential to the provision of safe surgical care and depends on three key aspects: adequate volume of blood supply, safe protocols for blood donation and transfusion, and appropriate regulation to ensure safe, equitable and sustainable distribution. Many low-income and middle-income countries experience a deficit in these categories, particularly in rural areas. We draw on the experience of rural surgical practitioners in India and summarise the existing literature to evaluate India's blood banking system and discuss its major barriers to the safe and equitable provision of blood. Many low-income and middle-income countries struggle with accruing a sufficient voluntary, unpaid blood donation base to meet the need. Efforts to increase blood supply through mandatory family replacement donations can lead to dangerous delays in care provision. Additionally, prohibition of unbanked, directed blood transfusion restricts the options of health practitioners, particularly in rural areas. Blood safety is also a significant concern, and efforts must be taken to decrease the risk of transfusion-transmitted infections and inform and treat donors who test positive. Lastly, blood banking systems need a centralised governing body to ensure fair prices for blood, promote comprehensive transfusion reporting and increase system-wide transparency and accountability.

Abstract
Transfusion transmitted infections are major problem associated with blood transfusion. Accurate estimates of risk of TTIs are essential for monitoring the safety of blood supply and evaluating the efficacy of currently employed screening procedures. The present study was carried out to assess the percentage of voluntary donors and replacement donors and to find out prevalence and changing trends of various TTIs blood donors in recent years. A study was carried out on blood units of voluntary and replacement donors which were collected from January 2008 to December 2012. On screening of 180,371 replacement units, seropositivity of transfusion transmitted disease in replacement donors was 0.15% in HIV, 1.67% in hepatitis B surface antigen, 0.49% in hepatitis C virus, 0.01% in VDRL, and 0.009% in malaria. Of 11,977 voluntary units, seropositivity of transfusion transmitted disease in voluntary donors was 0.08% in HIV, 0.24% in hepatitis B surface antigen, 0.001% in hepatitis C virus, 0.008% in VDRL (sexually transmitted disease), and 0.01% in malaria. From results it has been concluded that prevalence of transfusion transmitted infection (HIV, HBV, HCV, VDRL, and malaria) was more in replacement donors in comparison to voluntary donors. Extensive donor selection and screening procedures will help in improving the blood safety.

Abstract
OBJECTIVE To evaluate the rate of seropositivity to hepatitis B and C and Human Immunodeficiency Virus (HIV) infections among children with β-thalassemia major receiving multiple transfusions in Ahmedabad, India, compared with healthy controls. MATERIALS AND METHODS The study was performed during January 2007 to January 2009 on multi-transfused children suffering with β-thalassemia major registered in the Prathama Blood Centre, Ahmedabad; Jeevandeep hospital, Ahmedabad; and Red Cross Blood Centre, Ahmedabad, and investigated for the prevalence and development of transfusion-transmitted infections. Hepatitis B surface Antigen (HBsAg), anti-Hepatitis C Virus (HCV) Antibodies (Ab), and HIV Ab were checked using a fourth-generation Enzyme-Linked Immunosorbent Assay (ELISA). Positive tests were confirmed by western blots. Healthy blood donors were used for the control group. RESULTS Hepatitis B surface antigen, anti-HCV Ab, and HIV Ab were positive in one of 96 (1.04%; 95% Confidence Interval (CI) = 0.17-1.3), 24 of 96 (25%; 95% CI = 11.4-14.2), and one of 96 (1.04%; 95% CI = 0.12-1.3), respectively. The rate of anti-HCV Ab was significantly higher in multi-transfused children suffering with β-thalassemia major. In thalassemia patients, the rate of positive anti-HCV Ab was significantly higher than that for positive HBsAg (P<0.001) and HIV Ab (P<0.001). CONCLUSION It is concluded that HCV is the current major problem in multi-transfused children with thalassemia major and more careful pretransfusion screening of blood for anti-HCV must be introduced in blood centers.

Abstract
BACKGROUND A blood transfusion is a life-saving procedure in many instances. An adequate supply of safe blood is ensured by exercising donor deferral criteria and screening for Transfusion Transmitted Infections (TTI). The aim of this paper is to study the profile of blood donors and reasons for donor deferral in coastal South India. METHOD The study was conducted at a tertiary care hospital in Mangalore. All those who donated between 1 January 2008 and 31 December 2008 were included in the study. Data was collected using a pre-tested semi-structured proforma and analysed using SPSS version 11.5. RESULTS Most of the donors were under the age of 25 (42.92%). Donors were predominantly male (95.20%). In terms of occupation, most subjects were students (28.01%) followed by businessmen (18.61%). Slightly more than three-quarters of the donors (77.20%) were replacement donors. The main reasons for deferral were consumption of medication in the past 72 hours (15.15%), hypertension (13.18%), a low haemoglobin level (12.34%) and alcohol intake in the past 72 hours (12.20%). Among the TTIs identified, most samples were positive for Hepatitis B surface Antigen - HBsAg (0.87%) or tested positive for Anti-Hepatitis C (HCV antibodies (0.36%). CONCLUSION From the study it was concluded that the majority of the donor population was young and educated. The reason for donation was mainly replacement rather than voluntary. This issue needs to be addressed by exercising proactive measures to increase the number of voluntary, nonremunerated, low-risk donors.

Abstract
BACKGROUND This study presents data on the prevalence rate of infectious markers among voluntary and replacement donors in the blood transfusion service in Armed Forces from 2000 to 2004. METHODS 39,646 units of blood were collected from donors during the period from 2000 to 2004. All the samples were screened for hepatitis B surface antigen (HBsAg), human immunodeficiency virus (HIV) 1&2, hepatitis C virus (HCV), and by venereal disease research laboratory test (VDRL). RESULTS 24,527 (61.9%) were voluntary donations and 15,119 (38.1%) replacement donations. Prevalence of HBsAg had decreased, amongst voluntary donors from 1.67% to 0.77% but the positivity rate has not showed significant change. Seropositivity of HIV had decreased both in voluntary and replacement donors to 0.22% and 0.86% respectively. The seropositivity for anti-HCV showed steady decrease amongst voluntary donors from 0.46% to 0.20% in 2004, but in replacement donors, there was an increase in reactivity rate from 0.43% to 0.65%. CONCLUSION The increased seropositivity for HCV, HIV and HBsAg could be decreased by introduction of nucleic acid amplification testing (NAT) in minipools for HCV and HIV and introduction of anti-HBcAg (IgM) for hepatitis B virus (HBV) infection. But this may not be possible in near future in developing countries due to financial constraints. At present implementation of strict donor criteria and with use of sensitive laboratory screening tests it is possible to reduce the incidence of transfusion transmitted infections (TTI) in Indian scenario.

Abstract
The aim of the study was to assess the prevalence of HCV, HBV, and HIV infections among the patients with hemophilia. Patients with Hemophilia A and B were evaluated who visited hospital for factor replacement therapy. The viral markers tested in these patients included anti-HCV-Ab, HBsAg, and anti-HIV-Ab. Seroprevalence was compared from 5717 exchange healthy blood donors for same markers. A total of 173 multitransfused male hemophiliacs showed prevalence of 51.4% for HCV, 1.73% for HBV, and nil for HIV. In blood donors seroprevalence was 1.9% for HCV, 1.81% for HBV, while no HIV-positive case was detected. Prevalence of anti-HCV-Ab was significantly high in patients with hemophilia than normal donors (P = .0005). This study showed that HCV infection was more frequently identified than HBV and HIV infections in multitransfused hemophiliacs. The frequency of hepatitis C among blood donors is also higher than that of hepatitis B which is showing downward trend.

Abstract
BACKGROUND Transfusion-transmissible infectious agents such as hepatitis B virus (HBV), human immunodeficiency virus (HIV), hepatitis C virus (HCV) and syphilis are among the greatest threats to blood safety for transfusion recipients and pose a serious public health problem. This cross-sectional study was undertaken with the aim of determining the seroprevalence of HIV, HCV, hepatitis B surface antigen (HBsAg) and syphilis and correlates the findings with sex and age to ascertain the associations, if any, in the occurrence of the pathogens. MATERIALS AND METHODS HBsAg, antibodies to Treponema pallidum and HCV were determined using Clinotech test strips. Antibodies to HIV types 1 and 2 were screened with Determine and Immunocomb. All the reactive samples were confirmed using enzyme-linked immunosorbent assays. Antibodies to Treponema pallidum were confirmed with a Treponema pallidum haemagglutination test. RESULTS A total of 1,410 apparently healthy prospective blood donors aged between 18 and 64 years (mean+/-SD, 32.58 +/- 10.24 years) who presented for blood donation at the Ladoke Akintola University of Technology Teaching Hospital Blood Bank, Osogbo were studied. The male:female ratio was 6:1. Of the prospective blood donors, 406 (28.8%) had serological evidence of infection with at least one infectious marker and 36 (2.6%) had dual infections. The overall seroprevalence of HBsAg, HIV, HCV and syphilis was found to be 18.6%, 3.1%, 6.0% and 1.1%, respectively. The highest prevalences of HBsAg, HIV, HCV and syphilis infections occurred among commercial blood donors and those aged 18 to 47 years old, the most sexually active age group. There were no significant associations between pathogens except for syphilis and HIV (p > 0.001). CONCLUSION The high seroprevalence of blood-borne pathogens among prospective blood donors in Osogbo, Nigeria calls for mandatory routine screening of blood donors for HBV, HIV, HCV and syphilis.

Abstract
Blood component therapy is a very common intervention practiced in newborns; nearly 85% of extremely low birth weight (ELBW) babies get transfusions during their hospital stay. However, there are no set guidelines for transfusion of blood component therapy in newborns. This protocol includes available types of blood components, their methods of preparation, indications and side effects of transfusion, in relation to newborns.

Abstract
Jaundice is not an unusual accompaniment of malaria. It can occur due to intravascular hemolysis, disseminated intravascular coagulation, and, rarely, 'malarial hepatitis'. Although the primary schizogony of the malarial parasite always leads to the rupture of the infected hepatocyte, alteration of the hepatic functions is uncommonly recorded due to this event. Histologically, the hepatitis or the actual inflammation in the liver has never been demonstrated. Nonetheless, the term 'malarial hepatitis' (MH) has been used in the literature to describe the occurrence of hepatocellular jaundice in patients with Plasmodium falciparum infection. The authors' own data and review of the literature indicate that it is not an uncommon entity. In endemic areas, jaundice is seen in approximately 2.5% of patients with falciparum malaria. It also appears to be a heterogeneous syndrome and one can recognize two clinical subsets. In one group there was an acute, virulent presentation with coma, renal failure and in some cases even hemorrhagic manifestations. It is only in this setting that jaundice signified a 'severe' disease as noted by the World Health Organization action program. This presentation is often confused with acute viral hepatitis and acute hepatic failure in non-endemic areas, but can be clinically differentiated.

Abstract
Blood donors must respond to standard control questions and comply to certain demands before donating blood, to exclude possible recent contamination. This study investigates whether donors had adequate knowledge about 'the immunological window period', and whether the standard questionnaire in use was understandable and clear. It was found that nearly 40% of the donors had inadequate knowledge about 'the immunological window period' and that 10-40% of the donors would respond in various ways to different interpretations of the formulations of the questionnaire, indicating that the questionnaire was ambiguous. It was concluded that these factors could increase the risk of donating on wrong conditions. Demands and control questions posed to donors must be void of ambiguous formulations and take proper account of actual human sexual behaviours and life styles. Finally, it is suggested that blood banks must offer practical solutions (such as a 'fake donation') for temporarily rejected donors in order to respect their private integrity.

Abstract
The aim of this study was to assess the antibody response to combined passive active immunisation versus active immunisation along with interferon against Hepatitis B in 60 patients with acute lymphoblastic leukemia (ALL) between 1 and 21 years of age with negative Hepatitis B virus (HBV) serology at presentation. Thirty-one patients received combined passive active immunisation with human specific Hepatitis B immunoglobulin (HEPABIG-VHB Pharmaceuticals) and Hepatitis B vaccine (arm I) and 29 patients received active immunisation along with interferon (arm II). Protective antibody levels were detected in 89.6 and 21% patients, respectively, at the 6-month evaluation. Infection with HBV occurred in 17 and 59% patients, respectively, at the 6-month evaluation. Interferon, thus, failed to serve the role as a vaccine adjuvant. At the 9-month evaluation of patients who received immunoglobulin, protective antibody titers were lost in 8 out of 19 evaluable patients (42%) and of these, 3 patients became HBsAg reactive at this point of time. This study indicated that 47.3% patients undergoing aggressive chemotherapy responded to combined passive active prophylaxis with protective titers of antiHBs at the 9-month evaluation. However, the rate of HBV infection was greatly reduced to 27%. We suggest that usage of passive immunisation in the aggressive phase, followed by active immunisation after cessation of intense chemotherapy would be a better option to increase the rates of protective antibody levels in these immunocompromised patients with leukemia.
