We conducted a follow-up cohort study of volunteer blood donors who have made at least two blood donations in Bukavu (DRC) between January 2010 and December 2012. We recorded 2986 volunteer blood donors during the study period. The residual risk of viral transmission associated with the serological window was considered as equals to the incidence rate multiplied by the duration of the serological window period divided by 365. Seroprevalence in volunteer blood donors in Bukavu was 1.1% for HIV 1/2 antibodies, 4.0% for HBs Ag and 2.1% for hepatitis C antibody. The number of conversion between two blood donations (incident cases) were observed is 8, 12 and 37 donors respectively for HIV 1/2, HCV and hepatitis B between 2010 and 2012. Incidence rates reported for 1000 person-years were 11.0 for HIV, 51.7 for HBV and 17.1 for HCV. The residual risk as estimated from the window was 0.6 per 1000 donations or 1/1.515 donations for HIV, 3.1 per 1000 donations or 1/329 for HCV and 7.9 per 1000 donations or 1/126 donations for hepatitis B. The residual risk is high. The screening tests are not enough to ensure safe blood. The reduction of residual risk would be achieved through the effectiveness of preventive measures taken for transfusion chain, before and after the biological qualification of blood donation.展开更多

Methods: A cross-sectional study was conducted and enrolled 416 people between 18 and 65 years old at random, living in three health zones in the city of Bukavu in eastern DRC. These subjects responded to a questionnaire on knowledge, attitudes and practices regarding blood donation. Results: Our sample consisted of 61.5% men, 70.9% of people from one level of education at the secondary level and 60% unemployed. According to the surveyed subjects blood was considered as a fuel of the body in 44.6% and as a source of life in 44.1%. Sixty-one percent of the population did not know the practice of blood donation;this knowledge differed significantly (p < 0.0001) according to the level of education. 67.1% of people knew that the blood had negative effects and 27.4% did not know where the blood bags were stored. Channels of knowledge about blood donation practices were associations of blood donors (30.9%), awareness campaigns (18.2%), school (17.3%) and media (15.5%), churches (10%), and friends (8.1%). Approximately 85% of subjects who knew blood donation agreed with blood donation and blood transfusion but only 54.9% had donated blood in their lifetime, with a proportion of loyalty to blood donation (31.8%). In the population 59.4% were willing to donate blood. Motivation to donate blood most common (66%) was volunteerism while 19.1% were willing to donate blood for a family member and 12.6% willing to donate blood against money. The reasons for refusal to donate blood identified were fear of contracting diseases especially HIV, lack of information, religious beliefs, the sale of the collected blood by medical staff, and fear of test result for HIV. Conclusion: Factors of refusal to donate blood were identified. Efforts and new strategies tailored to these factors must be developed and implemented to increase blood donation.展开更多

Methods: This study is comparative cross-sectional. It covered all the staff care. Our sample was composed by doctors, nurses, midwives, and agents’ rapid training in activity in health sector in South Kivu between 1 December 2011 and 30 December 2011. Those medical and paramedical staffs came from 12 general reference hospitals, 11 hospitals and 65 health centers in the province of South Kivu. Three hundred and ninety three people were interviewed including 6.5% of physicians, 87.4% of nurses and 5.1% of midwives. Among them, 25.5% had received training in blood transfusion. Results: Overall, 11.7% of providers responded correctly to questions on knowledge and attitude on blood safety. The proportion of correct answers on the knowledge and attitude on exposure accidents was 53.8%. The frequency of caregivers who responded well to the basics of HIV and hepatitis B and C was 15.5%. Notions about the type of donor blood and the risk of blood transfusion received an overall rating of 17.8% and the proportion of correct answers on the knowledge and practice base of blood transfusion was 16.7%. During the six months following the survey, 54.4% of providers have experienced accidental exposure to blood. Conclusion: The lack of knowledge of the medical staff in transfusion is obvious. We must therefore have the possibility of organizing regular training and follow-up activities.展开更多

Materials and Methods: Descriptive and analytical study on pregnant women in the community Maniema (DRC) between 24 June and 24 July 2013. We enrolled a total of 581 pregnant women. Results: Prevalence among pregnant women was 4.1% (2.5% to 6.3%) for HIV, 5.9% (3.9% to 8.4%) for the HBsAg and 4.1% (2.5% to 6.4%) for hepatitis C. The risk factor was for HIV, blood transfusion history in women. For HBsAg the main risk factor was the tattoo history and no statistically significant factor was found for hepatitis C. Conclusion: To reduce the risk of transmission of hepatitis from mother to child, all pregnant women should be screened prenatally. A strengthening of routine screening of blood products must be done and a health education of the population on the mode of contamination should be conducted.展开更多

Materials and Methods: Descriptive and analytical study on children aged 6 to 59 months of community Maniema (DRC) conducted between 24 June and 24 July 2013. We enrolled 781 children aged 6 to 59 months. For association between the presence of viral markers and potential risk factors the chi-square test of Pearson was applied, the odds ratios (OR) and their 95% confidence intervals (95% CIs) were calculated. The Fisher exact test was used when the conditions for application of the chi-square test of Pearson were not met. Results: The median age of the children was 34 months, 51% of female children. Ten percent of children had a history of blood transfusion;6.6% and 64% had fever and anemia. The prevalence of HBsAg was 3.6%, the prevalence of antibodies against hepatitis C was 2.8% and HIV was 3.7%. The risk factors were HBsAg, male gender (5.5% male vs 2.0 % female;OR = 2.8(1.3 - 6.9) p = 0.001) and urban areas (5.0% rural vs 0.5% urban, OR = 0.1 (0.01 - 0.72), p = 0.01). For HCV and HIV, these factors were the history of blood transfusion in the child and the mother. For HCV 7.6% of children with blood transfusion history;OR = 3.2 (1.1 - 8.5);p = 0.05 and 11.1% history’s mother blood transfusion, OR = 5.6 (2.1 - 14.1). For HIV 11.4% of children with blood transfusion history, OR = 3.8, p = 0.005 and 9.8% history’s mother blood transfusion, OR = 2.9, p = 0.04. Conclusion: Vaccination against hepatitis B in children must be widespread, educational messages to the population must target the risk factors for these viruses. A screening of hepatitis in pregnant women must be coupled with rigorous selection policy for blood donors before each donation and qualification of any unit of blood.展开更多
