The existence and sustenance of the blood bank depends on blood donors. It is imperative that the donation experience is satisfactory for the donors. Therefore this study was carried out to determine the frequency of undesirable events experienced by the blood donor as part of donor haemovigilance. This was a retrospective descriptive study of the events that occurred amongst the blood donors of the blood bank of a tertiary institution. The blood donor incident book was reviewed for the period of six months. Negative undesirable events occurred in 2% of the donor populations, of which 45.8% could not complete the blood donation process while only 16.7% completed the blood donation process. Mild vasovagal attack occurred in 0.2% of the donor population. Undisclosed deferrable risk factors/ behaviours were identified by the phlebotomist in the bleeding room which made donors unfit for donation even though they had passed the donor screening criteria. This accounted for 20.8% of those with negative experience. Guidelines are required to identify donors that are not likely to complete donation to avoid wastage of time, blood, resources and reduce undesirable experiences.

Microbiological safety is very important aspect of blood transfusion services (BTS). Viral infectious agents possess a great risk of transfusion transmitted disease. On the one hand, blood or component transfusion is a lifesaving modality but on the other hand it can cause great mortality or morbidity in recipient if not used judiciously. The main aim of the study is to evaluate the prevalence of HIV, HBV, HCV, Syphilis and Malaria amongst all types of donors donated at blood bank of Sir Sunderlal Hospital, Institute of Medical Sciences, Banaras Hindu University, Varanasi during the year 2017. This was a retrospective study. The blood donors included in this study include all donors coming directly to blood bank and blood donation camps organized by blood bank. Total donation during that period was 22255 units. A detailed questionnaire was given to the donors for registration. A total of 226 units (1.01%) were seropositive. The sero-prevalence of HIV, HBV, HCV, and Syphilis were 0.9% (21), 0.79% (177), 0.09% (22), 0.02% (6) respectively. No cases of malaria were detected. TTI can be reduced by motivating maximum voluntary blood donation, reducing replacement donation, public information and donor education awareness programme, stringent donor screening criteria and vigilance of error.

Introduction: The blood transfusion (BT) system in Pakistan is fragmented, demand-driven, and depends on weakly regulated transfusion practices. This is primarily a big problem in smaller cities and remote rural areas. Pakistan has one of the highest hepatitis B virus (HBV) and hepatitis C virus (HCV) prevalence worldwide, estimated around 5 & 10 million cases, respectively. There is a considerable risk that transfusion-transmissible infections (TTIs) may have contributed to the current epidemic of HBV & HCV, affecting 7.4 % of the general population, and potential risk of HIV transmission in the country. In this systematic review, we aim to identify the prevalence of TTIs among the blood donor population and associated safety challenges. Method & Material: We conducted a systematic literature search to identify studies related to TTIs and transfusion safety in Pakistan from January 1, 2010, to January 31, 2020. A search was conducted using PubMed and PakMedinet.com (largest medical database of Pakistan); initial search retrieved 981 articles, 166 met the inclusion criteria, and after review by two independent reviewers, 33 articles met the final criteria for qualitative synthesis. Results: Analysis of 33 studies showed the seroprevalence of HBV of 2.04 % (0.81% to 4.22%), HCV of 2.44% (1.29 % to 10%), HIV of 0.038% (0% to 0.18%), syphilis of 1.1% (0.11-3.01%) and malaria of 0.11% (0.05-1.20). The rate of coinfections among blood donors varied from 0.0099% to 0.35 %. The highest number of coinfections were HCV & syphilis, followed by HCV & HBV infections. The rate of TTIs was dependent on the number of donors, donor types (replacement vs. voluntary), screening techniques used, number, and type of TTIs tested. There was a lack of universal screening for common TTIs. Syphilis and malaria were tested only 38 % & 46 % of all the blood donations. The studies with a high number of replacement donors (RDs) noted a high prevalence of TTIs of 2.5 % to 12 % compared to the studies with a high number of voluntary non-remunerated donations (VNRDs) reported TTIs rates of 1.57% to 6.2 %. There was a significant difference in the prevalence of HBV & HCV in VNRDs (0.48%) compared to RDs (4.15%). The rate of VNRDs was 0.10 % to 13%. The majority of blood donations were from male donors, representing more than 70 % of all donations. The female donations varied from 0.03% to 15 % in government/public blood banks than 29 % in private sector blood banks. The HBV & HCV infections and anemia were the most common causes of blood donation deferral. The 69.5 % of donors who tested positive for TTIs in a study reported previous blood donations. The educational status of donors noted to have an association with knowledge about the risk of TTIs. Odds of having limited knowledge about TTIs (OR: 4.04, CI: 1.567-10.435, p<0.01) were greater if donors had a secondary level of education compared to those with tertiary education. 48 % of blood donors did not know about the risk of TTIs through blood transfusion. There was notification of only about 54.25 % of all donors, who tested positive for any TTIs. This was mainly due to a lack of standardized reporting and follow up systems. Conclusion: This systemic review shows a high prevalence of TTIs, especially HBV, HCV & syphilis in the blood donor population. There is a high dependency on RDs, with 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 donors about their health. There is a lack of widespread standardized testing and follow up of patients who tested positive on initial testing. Large prospective multicenter clinical trials are required for a better understanding of the TTIs by testing and creating a follow-up system for both blood donors and recipients.

AbstractObjectiveThe objective of this study is to determine the prevalence of iron deficiency (ID) and iron deficiency anaemia (IDA) as well as general anaemia in male blood donors and their association with ageing process.Methodology and ResultsA total of two hundred and one (201) serum samples were analysed for ferritin in male Gambian blood donors. The ferritin measurement was achieved with COBAS® INTEGRA 400 plus. At the same time, haemoglobin values were retrospectively obtained from the archived haematological full blood count result in the GARIS database. IDA was defined as (Haemoglobin <13.0g/dL+ Ferritin<15ng/ml) whilst ID was defined as (Haemoglobin ≥13.0g/dL+ Ferritin<15ng/ml) and general anaemia was defined as haemoglobin <13.0g/dL in males. The prevalence of anaemia (20%, n=41), ID (22%, n=44) and IDA (10%, n=21), were recorded in male donors. The results show no relationship between ferritin and haemoglobin among the blood donors (collection coefficient (r) = 0.04). Besides, no linear association of having anaemia and ID with ageing was reported among the blood donor population.Conclusion and potential application of findingsID and IDA as well as general anaemia are highly prevalent among blood donors in the Gambia. Besides, no predisposition to ID and anaemia was observed in term of age, thus all blood donors from 18-60 should be considered for blood donation without any age preference.

Background: HCV is known for its chronicity and leads to cirrhosis in about 10 to 20 per cent of patients and may further progress to hepatocellular carcinoma (HCC). The global seroprevalence of HCV among blood donors varies from 0.4 to 19.2 per cent and the estimated risk for HCV transmission is between 0.10 to 2.33 per million units transfused. ELISA is the most commonly used initial assay for detecting HCV antibodies. The purpose of the present analysis was to monitor the seroprevalence of anti-HCV antibodies in the blood donor population in a hospital based blood bank in north India for a period of 10 years (2007-2016), and to evaluate the trends over the years.Methods: The purpose of the present analysis was to monitor the seroprevalence of anti-HCV antibodies in the blood donor population in a hospital based blood bank in north India for a period of 10 years (2007-2016), and to evaluate the trends over the years.Results: Of the total 340078, 298421 (87.75%) collections were voluntary and 41657 (12.25%) were replacement collections. A prevalence of 0.72% of hepatitis C virus infection was seen among the donors from the period 2007-2016. The trend of hepatitis C prevalence among donors has been fluctuating while ranging from 0.51% to 0.89%.Conclusions: For a safe blood service in our country, where comprehensive laboratory tests are neither possible nor pragmatic, it is best to switch over to 100% voluntary donations, as it is now established that only voluntary non-remunerated regular donation is the safest. Thus, one of our key strategies to enhance blood safety is to focus on motivating non-remunerated blood donors and phasing out even replacement donors. Since, no vaccine is presently available for immunization against HCV infection, transfusion transmitted HCV infection remains a potential threat to the safety of the blood supply.

Background: In India, about 60% of donation is through voluntary blood donors. However, about one third already motivated blood donors are deferred due to stringent screening criteria, either temporarily or permanently. The temporarily deferred donors could be a good source of blood donation after deferral period. The objective of this study was to know the main causes of pre-donation deferral in potentially healthy prospective blood donors, to investigate impact of deferral on donation pattern and to evaluate impact of post deferral counseling on donation pattern.Methods: The present study is carried out in A. D. Gorwala blood bank in Anand, Gujarat from April 2014 to September 2015. All donors screened as per the guideline and deferred donors are categorized as temporary and permanently deferred donors. A Comparison group of healthy eligible donors who donate blood at ADGBB is also studied to determine impact of deferral on donation pattern. From temporarily deferred donors, reason for deferral is considered. At the time of deferral, donors properly counseled, clearly informed about the reason of deferral and corrective actions are taken. As per reason of deferral, time duration for recalling the donor is defined. Based on this, donor is called back to donate again for up to six month’s period after expiration of deferral period.Results: Total 12.57% donors were deferred temporarily. Significant female preponderance was observed (58.7% vs 8.90%). Low hemoglobin (60.9%) was the most common reason of temporary deferral followed by abnormal BP and medicine ingestion. Total 378 donors were responded back out of 953 of deferred donors compare to 645 in non-deferred group. Middle age, male, repeat donors, in-house donors, high education, high socio-economic status, shorter duration of deferral appears to significantly predict donor return. In the evaluation of reasons of the re-deferral, Low hemoglobin was the prime reason. Unfavourable location, lack of time and change in job/college are major barrier to donor return. Total 39.60% response observed after post deferral counseling in present study compared to 11.20% in year 2013-2014.Conclusions: Efforts to increase the hemoglobin will improve the donor retention and overall blood safety can be increased. Temporary deferral has negative impact on donor return and duration of response after expiration of deferral, both in first time and repeat donors. Interventions to increase return behavior need to be better targeted at specific donor groups and it should be developed according to major barriers to donor return prevalent in particular region mainly through more effective communication with donors. Education, motivation, post deferral counseling.

Abstract INTRODUCTION: Janus kinase 2 gene (JAK2) encodes for a cytoplasmic tyrosine kinase involved in normal hematopoietic growth factor signaling. Point mutations of the JAK2 gene on chromosome 9, specifically V617F, a point mutation at amino acid 617, are associated with myeloproliferative disorders (MPD). The V617F JAK2 mutation has been found in 90% of patients with polycythemia vera, 50–60% of patients with essential thrombocythemia or idiopathic myelofibrosis and 1–5% of patients with other MPD. To our knowledge, previous studies involving the V617F JAK2 mutation were not performed on a control population of normal individuals. Therefore, the prevalence of this mutation has not been established. In this study, we tested volunteer blood donors from a hospital-based blood donation center for the presence of the V617F JAK2 mutation. METHODS: Citrated whole blood was obtained from volunteer blood donors, age 17 and older, who presented to donate whole blood at a hospital-based blood donation center. The donors met all qualifications to donate blood as defined by FDA regulations. DNA was extracted using the QIAagen and QIAamp DNA extraction columns, quantified and diluted to 100ng/ul. DNA was simultaneously amplified and detected using allele specific minor groove binder probes and primers for the V617F JAK2 mutation. The resultant amplification was recorded by real-time, quantitative PCR using an ABI 7500 (Applied Biosystems, Foster City, CA). A 1% limit of detection, determined from sensitivity and specificity studies using a known cell line control, was set as the technically reproducible threshold sensitivity of the test. Samples were defined as negative for the V617F JAK2 mutation if only the wild type allele was detected. Samples that had a mutant allele detected above the 1% limit of detection were defined as positive for the V617F JAK2 mutation. Samples that had a mutant allele detected below the 1% limit of detection were defined as negative for the V617F JAK2 mutation. RESULTS: A total of 181 DNA samples from volunteer blood donors were tested for the V617F JAK2 mutation. The test group consisted of 104 males (mean age 44, range 17–77) and 77 females (mean age 42, range 18–71). Of the 181 donors tested, 171 had only wild type allele detected and were considered negative. Ten donors had high background of the mutant allele detected below the 1% limit of detection and were considered negative. DISCUSSION: To our knowledge, this is the first report documenting the prevalence of the V617F JAK2 mutation in a healthy blood donor population. In this study of 181 volunteer blood donors none had the V617F JAK2 mutation. Although 10 of the 181 donors were found to have mutant allele detected, they were below the 1% technically reproducible sensitivity threshold of the test and were considered negative. We recommend that mutations detected below the technical threshold of 1% of our assay be considered false positives. The results of this study suggest that the V617F JAK2 mutation is not present in a healthy blood donor population and is significant when detected by our method.

Background: Blood transfusion saves lives and improves health, but many patients requiring transfusion do not have timely access to safe blood. Providing safe and adequate blood should be an integral part of every country’s national health care policy and infrastructure. Aim: The main aim of the study was to analyze the reasons for pre-donation deferral amongst blood donors attending our blood bank and outdoor camp organized by our blood bank and to evaluate and categorize the reasons into temporary and permanent deferral. Materials and methods: It is a Record based Retrospective Study conducted in Department of Immunohematology and blood transfusion over a period of two years from July 2015 to July 2017. The reasons of deferral were analyzed after classification into following categories, namely, temporary- permanent deferral, in-house –camp blood donors, gender-based (male -female), and various age group categories. Results: A total of 30,022 prospective blood donors registered for blood donation out of which 2241 blood donors were deferred (7.46%) with low hemoglobin level, medication and hypertension as top three causes. The majority of deferral was seen in 18-25 years of age group which mainly comprises the youth population. The female donors were rejected eight times the male donors. Conclusion: The knowledge of the deferral incidences and their causes in a particular region helps in deciding the magnitude and the direction of the blood donor recruitment efforts. This knowl­edge also helps in calculating the eligible and the potential blood donor pool. Keywords: Blood Donors, Pre-Donation, Deferral, Temporary, Permanent.

Background: Timely transfusion of blood saves millions of lives, but unsafe transfusion practices puts millions of people at risk of transfusion transmissible infections (TTIs). Blood transfusion carries the risk of transfusion-transmissible infections including human immunodeficiency virus (HIVI&II), hepatitis B virus (HBV), hepatitis C virus (HCV), malaria and syphilis. With every unit of blood there are 1% chances of transfusion associated diseases.Methods: This study was conducted over a period of 3 years (1stJanuary 2015-31st December 2017) at hospital blood bank of Pt. Jawaharlal Nehru Government Medical College, Chamba (H.P). The study was conducted on both voluntary and replacement blood donors who came to our blood bank and voluntary blood donation camps in and around Chamba. Statistical analysis used. Collected data was analyzed using appropriate statistical softwares such as EPI-INFO and MS-Excel.Results: In our study, we observed a total of 2616 donors over a period of 3 years. In the present study, 847 (32.37%) were voluntary donors and 1769 (67.62%) were replacement donors. Out of 2616 blood samples, 8 were HBsAg positive, 1 HCV positive.Conclusions: Our study shows that the number of blood donors is increasing every year. In our study, the seroprevalence of HBsAg was 0.3% and Hep C was 0.03% in total blood donors. The knowledge of current infectious disease pattern and trends in donor population can help in planning of future blood transfusion related health challenges.

Objectives This article aims to analyse the safety of feline blood donation by describing the frequency and nature of any adverse reactions and their causes, as well as propose measures to decrease the incidence of adverse reactions. Methods In this prospective study, any blood donor adverse reactions detected by the clinical staff during and immediately after donation were recorded. The owners of the cats were also surveyed by a veterinary practitioner or veterinary nurse 5 days after donation, using a predefined questionnaire to assess for any clinical or behavioural changes. Data were collected between January 2019 and March 2020 from blood donors enrolled in an animal blood bank programme. Results Of 3690 blood donations from 1792 feline donors assessed, post-donation reactions were reported in 1.14% (n = 42): 0.22% (n = 8) were acute reactions, which included weakness, pallor, tachypnoea and open-mouth breathing; and 0.92% (n = 34) were delayed post-donation reactions, with 0.16% involving cutaneous (haematomas and skin rashes, n = 6), 0.68% involving behavioural (n = 25) and 0.08% involving digestive (emesis and inappetence, n = 3) signs. Conclusions and relevance The low incidence of post-donation reactions in this study is encouraging, suggesting that a well-established protocol and competent staff can help to ensure a high level of safety in a feline donor programme and, in turn, increase the confidence of cat owners.

Donor Deferral

Background: Blood donor programme is vital to any transfusion service. This process of blood donation involves voluntary and non remunerated blood donors. The objective of donor screening is to minimize the chances of transmitting infectious agents to recipients. Material and Method: The study was conducted during one year duration from 2017-2018. A total of 700 donors are deferred against 9556 blood donors recruited on the basis of clinical history and brief medical examination in blood bank and voluntary blood donation camps. Donors were deferred temporarily or permanently. Result: Out of 700 deferred donors; 546 were voluntary and 154 were replacement blood donors. Male (601) outnumbered female (99). There were 682 temporary and 18 permanent deferral. Most common age group for deferral was 17-30 yrs (490). Common causes included anemia(142), on medication(108), underweight(83) and high blood pressure(72). Conclusion: Donor selection process is a most important preliminary step in blood banking and should follow stringent medical and regulatory rules. Studying and analysing the profile of blood donors will help to identify sections of the population which could be targeted to increase the pool of voluntary blood donors. Every attempt should be made to decrease the donor deferral keeping in view the safety of both donor and recipients. Keywords: Blood donor, Deferral, Voluntary, Temporary, Permanent.
