Blood transfusion is a salutary practice in modern medicine, but it carries a high risk of transmission of transfusion transmitted infections (TTIs), especially in developing countries. The objective of this study is to determine the seroprevalence of viral hepatitis B among blood donors. This is a retrospective and descriptive cross-sectional study of the period from 2014 to 2016 at the Katele Health Reference Center (Moba, DR. Congo). We investigated HBsAg in blood donors by using Determine ® HBSAg. 1145 blood donors with an age mean of 30.6 ± 6.9 years and predominantly male (62.5%) were retained.

The determination of blood groups appears to be very useful in transfusion medicine, genetics, forensic medicine, organ transplantation and maternal alloimmunization. In Moba, blood transfusion is indicated in several anemias of the children. The present study aimed to determine the frequency of ABO and Rhesus blood groups in our environment. This is a descriptive cross-sectional study. Blood donors registered at the Moba General Reference Hospital for the period 2015 to 2016 were selected for this study (n = 2292). The Beth-Vincent test was used to determine blood group phenotypes from the monoclonal test sera. Blood groups O (60.5%) and AB (2.5%) were respectively the most frequent and the least encountered. In our series of studies, the numerical frequency order of the phenotypes of the ABO and Rhesus (D) blood groups included in order of importance: O + (n = 1364 or 59.5%); A + (n = 488 or 21.3%); B + (n = 348 or 15.2%); AB + (n = 55 or 2.4%); O − (n = 22 or 1.0%); A − (n = 7 or 0.3%); B − (n = 5 or 0.2%); and AB − (n = 3 or 0.1%). This observed difference between the different ABO and Rhesus groups is significant. Sex does not significantly affect the type of blood group. The distribution of ABO and rhesus groups follows the same Negroid distribution as in many countries. The results should be capitalized for proper priority management of the blood to be stored in the blood bank.

Birth weight anomalies (Macrosomy and Dysmaturity) and gestational age (premature and post-term) are a real public health problem, especially in resourceconstrained countries. The newborn is exposed to great morbidity and mortality. This study aims to determine the frequency and early neonatal mortality related to anomalies in birth weight and gestational age in our environment. This is a retrospective and descriptive three-year study (2011)(2012)(2013) at the Maternity services of the General Reference Hospital of Lubao (Lomami Province, Democratic Republic of Congo). Out of a total of 1158 live babies retained for this study, 378 cases (32.6%) of birth weight and gestational age abnormalities were noted: 12.7% of birth and 19.9% for gestational age anomalies. Premature was much observed (n = 165 or 14.2%) followed by dysmature (n = 99 or 8.6%), post-term (n = 66 or 5.7%), and macrosomes (n = 48 or 4.1%). These anomalies had resulted in 122 cases (10.5%) of early neonatal

In sub-Saharan Africa, sexually transmitted infections (STIs) and transfusiontransmissible infections (TTIs) are a public health problem. Among them, we find the syphilis that the recipient of blood might contract in the absence of serological tests in the donor. The objective of this study was to determine the prevalence and profile of the individual at risk for transmission of Treponema pallidum among blood donation candidates. This is a single-center, retrospective and descriptive cross-sectional study over a period from 2015 to 2016 at the Katele Health Reference Center of Moba-Port in the Democratic Republic of Congo. The use of Rapid Plasma Reagin (RPR) was required for the detection of anti-treponematosis antibodies. The Epi Info 7.1 software was used to analyze the data at the significant threshold of p 0.05. Of 752 blood donors tested, 62.8% were male and the mean age was 30.3 ± 6.9 years with extremes ranging from 18 to 43 years. Family, replacement donors were the most encountered 2/13OALib Journal was encountered. The risk of contracting syphilis after transfusion remains high in our environment. It is mandatory to continue to research the Treponema pallidum in the serum of any blood donor. Education of the population on prevention of sexually transmitted infections and transfusion safety measures (especially during the donor screening phase) should be strengthened.
