          Abstract

          Objective

          This study aims to determine the distribution of blood groups and the demographic background of blood donors in a referral hospital in Northern Tanzania.

          Results

          The most common blood group was O (52.3%) and the least common was AB (3.18%). 97.7% of the blood donors were Rh positive and the rest were Rh negative. Most donors were young adults, representing the age group of 19–29. The majority of donors were male (88.1%) and the majority (90.8%) were replacement while the remainder was voluntary donors.

          Genome-wide association study identifies variants in the ABO locus associated with susceptibility to pancreatic cancer.

          Laufey Th Amundadottir, Peter Kraft, Rachael Z. Stolzenberg-Solomon … (2009)
          We conducted a two-stage genome-wide association study of pancreatic cancer, a cancer with one of the lowest survival rates worldwide. We genotyped 558,542 SNPs in 1,896 individuals with pancreatic cancer and 1,939 controls drawn from 12 prospective cohorts plus one hospital-based case-control study. We conducted a combined analysis of these groups plus an additional 2,457 affected individuals and 2,654 controls from eight case-control studies, adjusting for study, sex, ancestry and five principal components. We identified an association between a locus on 9q34 and pancreatic cancer marked by the SNP rs505922 (combined P = 5.37 x 10(-8); multiplicative per-allele odds ratio 1.20; 95% confidence interval 1.12-1.28). This SNP maps to the first intron of the ABO blood group gene. Our results are consistent with earlier epidemiologic evidence suggesting that people with blood group O may have a lower risk of pancreatic cancer than those with groups A or B.

            Blood transfusion safety in Africa: a literature review of infectious disease and organizational challenges.

            Edward Laurence Murphy, Marion Vermeulen, Konrad E. Bloch (2012)
            Blood safety remains an important public health concern in Africa where lack of availability or provision of unsafe blood adversely impacts morbidity and mortality in the region. In recognition of this shortfall, the World Health Organization (WHO) established a goal of regional blood safety by 2012 through improved "organization and management, blood donor recruitment and collection, testing of donor blood as well as appropriate clinical use of blood" (Tagny et al: Transfusion. 2008;48:1256-1261; Tapko et al: Status of Blood Safety in the WHO African Region: Report of the 2006 Survey http://www.afro.who.int/en/divisions-a-programmes/dsd/health-technologies-a-laboratories.html. Brazzaville, Republic of Congo: WHO Regional Office for Africa; 2006). Although there has been substantial progress toward meeting these objectives, there are continued obstacles to both development and sustainability. In a setting where transfusion oversight is still being improved, transfusion-transmitted infections are of real concern. The high prevalence of some transfusion-transmissible agents such as hepatitis B virus and HIV in the general population means that some infected blood units escape detection by even well-performed laboratory testing, resulting in potential downstream transmission to patients. The spectrum of transfusion-transmitted infection include conventional as well as exotic pathogens, many of which are endemic to the region, thereby imparting ongoing challenges to recruitment and testing strategies.

              ABO blood group, hepatitis B viral infection and risk of pancreatic cancer.

              De-Shen Wang, Dong-Liang Chen, Chao Ren … (2012)
              Little is known about the role of association between ABO blood type and risk of pancreatic cancer develops through effects on hepatitis B viral (HBV) infection. Our study aimed to determine whether joint ABO blood type and HBV infection could increase the risk for pancreatic cancer. A total of 645 patients with pancreatic adenocarcinoma and 711 age- and sex-matched individuals who had nonmalignant diseases treated at the Sun Yat-sen University Cancer Center in China were retrospectively analyzed. Blood samples were tested for ABO blood type and hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), hepatitis B e antigen (HBeAg), hepatitis B e antibody (anti-HBe) and hepatitis B core antibody (anti-HBc). Multivariable unconditional logistic regression analysis was used to estimate adjusted odds ratios [AORs] and 95% confidence interval [CI]. Multivariable analysis with adjustment for risk factors showed that A blood type, HBsAg-positive/anti-HBc-positive, anti-HBs-positive/anti-HBc-positive were significantly associated with pancreatic cancer. The estimated AORs (95% CI) were as follows: A blood type, 1.425 (1.071-1.894), HBsAg-positive/anti-HBc-positive, 1.610 (1.125-2.304), anti-HBs-positive/anti-HBc-positive, 1.526 (1.159-2.011). The effect of A blood type significantly modified the risk of pancreatic cancer among subjects with anti-HBc-positive (AORs = 1.882, 95% CI, 1.284-2.760). In our study, we reported an association between A blood type, infection with HBV and pancreatic cancer risk. Moreover, we found a synergism between A blood type and HBV infection in the development of pancreatic cancer. Copyright © 2011 UICC.
