ABSTRACT

BACKGROUND/OBJECTIVES: Healthcare professionals (HCPs) play a key role in the prevention of hepatitis B virus (HBV) infection. HCPs are expected to have adequate basic knowledge of HBV and readily uptake HBV vaccination as they are a high-risk group, especially those that have direct contact with blood and/or blood products. This study was aimed at assessing the knowledge of and vaccination uptake of HBV among HCPs in a Nigerian tertiary hospital. METHODS: This was a cross-sectional study in which self-administered questionnaires were used to obtain data from different categories of HCPs in a tertiary hospital. The associations between categorical variables were tested using Chi-square test and a P value of 0.05 or less was considered significant. RESULTS: A total of 355 HCPs comprising 149 medical doctors, 180 nurses and 26 laboratory scientists participated in the study. Majority (90.0%) of the respondents correctly identified blood and/or blood products transfusion, needle stick injury, sharing of sharps and vertical transmission as routes of HBV transmission. About 83.4% of the participants were aware that HBV could be transmitted through unprotected sex. However, 39.2% and 15.8% of the participants reported kissing and HBV vaccination as routes of transmission, respectively. Their knowledge and uptake of HBV vaccination was, however, good. CONCLUSION: While majority of the HCPs had good knowledge of the routes of HBV transmission, few still had misconceptions about the routes of transmission, a situation which may cause social discord in the society especially among closely related individuals and potentially result in poor uptake of the highly effective HBV vaccine.


CONTEXTE/OBJECTIFS: Les professionnels de la santé jouent un rôle clé dans la prévention de l'infection par le virus de l'hépatite B (VHB). On s'attend à ce qu'ils aient des connaissances de base suffisantes sur le VHB et qu'ils acceptent facilement la vaccination contre le VHB car ils constituent un groupe à haut risque, en particulier ceux qui sont en contact direct avec du sang et/ou des produits sanguins. Cette étude visait à évaluer les connaissances et l'acceptation de la vaccination contre le VHB parmi le personnel soignant d'un hôpital tertiaire nigérian. MÉTHODES: Il s'agit d'une étude transversale dans laquelle des questionnaires auto-administrés ont été utilisés pour recueillir des données auprès de différentes catégories de professionnels de la santé dans un hôpital tertiaire. Les associations entre les variables catégorielles ont été testées à l'aide du test du chi carré et une valeur P de 0,05 ou moins a été considérée comme significative. RÉSULTATS: Au total, 355 professionnels de la santé, dont 149 médecins, 180 infirmières et 26 laborantins, ont participé à l'étude. La majorité (90,0 %) des personnes interrogées ont correctement identifié la transfusion de sang et/ou de produits sanguins, les blessures par piqûre d'aiguille, le partage d'objets tranchants et la transmission verticale comme étant des voies de transmission du VHB. Environ 83,4 % des participants savaient que le VHB pouvait être transmis lors de rapports sexuels non protégés. Cependant, 39,2 % et 15,8 % des participants ont déclaré que le baiser et la vaccination contre le VHB étaient des voies de transmission, respectivement. Leur connaissance et leur participation à la vaccination contre le VHB étaient cependant bonnes. CONCLUSION: Alors que la majorité des professionnels de santé avaient une bonne connaissance des voies de transmission du VHB, quelques-uns avaient encore des idées fausses sur les voies de transmission, une situation qui peut causer des discordes sociales dans la société, en particulier parmi les personnes étroitement liées, et potentiellement entraîner une faible utilisation du vaccin hautement efficace contre le VHB.

ABSTRACT

BACKGROUND: Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is a major public health problem in sub-saharan Africa. Cytomegalovirus (CMV) has been reported to enhance HIV replication and accelerate the progression of HIV infection to AIDS. OBJECTIVE: This study reports on the high seropositivity of immunoglobulin (Ig) G and M antibodies against CMV and the risk factors for CMV infection among HIV/AIDS patients in Ilorin, Nigeria. METHOD: A total of 180 consented HIV-1 seropositive patients (age-range 16-56 years; 108 females and 72 males) were consecutively recruited. Socio-demographic/behavioral data and 5 ml blood samples were collected from each patient. Plasma of each sample was assayed for anti-CMV IgG/IgM using a CMV IgG and IgM Enzyme Linked ImmunoSorbent Assay (ELISA) kit. RESULTS: Twenty (11.1%) of the 180 HIV-1 seropositive subjects were positive for anti-CMV IgM antibody while 169(93.9%) were positive for anti-CMV IgG antibody. Age, marital status, number of sexual partners, CD4 cells counts and previous history of blood transfusion were the main correlates of CMV seropositivity among these patients. However, occupation, sex, highly active antiretroviral therapy (HAART) were not statistically associated with CMV seropositivity in this study. CONCLUSION: This study has shown that greater percentages of HIV-1 seropositive patients had active CMV infection. It has further shown that CMV is hyperendemic in HIV-1 seropositive patients in Ilorin, Nigeria.
