RESUMEN

BACKGROUND: Malaria and HIV are 2 significant infections of critical public health concern globally. Malaria infection is one of the preceding causes of morbidity and mortality in endemic developing countries, and its co-infections in HIV patients worsen prognosis; with anaemia being the most common haematologic outcome of the infections. CONTEXT AND PURPOSE OF STUDY: This study was aimed at determining the prevalence of anaemia and malaria co-infection among HIV-infected patients attending selected hospitals in Abuja between February and July 2019. METHODS: A cross-sectional study was carried out to detect malaria in 420 HIV-positive patients who were 12 to 67 years old, using enzyme immunoassay and microscopy. A structured questionnaire was used to capture socio-demographic and risk factors ([Frequency of] Use of Malaria preventive Measures, History of anaemia, Blood type, malaria antecedents, and CD4+ Count) while packed cell volume was checked using micro haematocrit reader to determine anaemia status. Data were analysed using IBM SPSS v25. RESULTS: The mean age of the study participants was 37.5 (±12.48). A total of 142 (33.8%) samples were positive for malaria, and 68 of the HIV-infected patients (16.2%) were anaemic; 4.8% of the 420 patients had malaria co-infection and anaemia simultaneously. More male participants had malaria co-infection (36.0%, P = .617) while more female participants had anaemia (22.7%, P = .058). Patients aged 61 to 70 years had the highest rates of malaria and those aged 51 to 60 years were most anaemic. Except for patients with normal CD4+ count, those who were more exposed to the evaluated risk factors were more co-infected and anaemic. Malaria co-infection did not significantly affect the onset of anaemia. Test for the validity of Microscopy against Enzyme Immunoassay (EIA) showed 83.1% sensitivity and 98.6% specificity. No association was observed between the variables and the parasitaemia density of the patients. CONCLUSIONS: This study highlighted higher rates of malaria co-infection and anaemia among HIV patients when compared with previous reports in the region although co-infection did not significantly affect anaemia status. Given this trend, strategies must be put in place to checkmate these ailments. Population studies are also advocated.

RESUMEN

Hepatitis B and C are liver diseases caused by hepatitis B and C viruses, and co-infection in HIV-positive individuals is common, with increased mortality and morbidity. This study determined the seroprevalence of HIV co-infection with the two viruses among patients attending three major hospitals in the Federal Capital Territory, Nigeria. From February to July 2019, 311 sera samples were collected from HIV positive patients and screened for Hepatitis B and C infection. Immunochromatographic and ELISA techniques for HBsAg and HCV were used. Socio-demographic features and responses to risk factors were obtained using questionnaires. Patients' data and results obtained were analyzed with SPSS version 25. The prevalence of HIV/HBV/HCV, HIV/HBV, and HIV/HCV co-infection were 0.64%, 6.43%, and 3.86%, respectively. The triple infection and both co-infections were preponderant among females than males, with a prevalence rate of 0.64%, 3.85%, 2.57%, and 0%, 2.57%, 1.29%, respectively. People aged 31-40 years had the highest triple infection (0.64%) and HIV/HCV infection rate (2.57%), while patients aged 21-30 years had the highest HBV co-infection (3.22%) rates. Widowed patients had the most co-infection rate in all cases. High-risk behavior indicated that there was a significant association between blood donation/reception and engagement in unprotected sex and HIV/HBV/HCV co-infection. The other risk factors revealed no significant effect (p > .05). There was generally a low rate of exposure to associated risk factors. This study highlighted the endemicity of hepatitis virus co-infection in Abuja and the existence of few reports of HIV co-infection with HBV and HCV compared to the nation's population.

RESUMEN

OBJECTIVES: This study was aimed at determining human T-lymphotropic virus 1/2 prevalence among apparently healthy, immunocompromised and haematologic malignant individuals in Nigeria's capital, as well as meta-analysis of all Nigerian studies until date. METHODS: A total of 200 participants were recruited into a cross-sectional study. In total, 1 mL each of sera and plasma were obtained from 5 mL blood of each participant and analysed for antibodies to human T-lymphotropic virus 1/2 using enzyme-linked immunosorbent assay; positive samples confirmed with qualitative real-time polymerase chain reaction, followed by statistical and meta-analysis. Sociodemographic characteristics and possible risk factors were assessed via questionnaires. RESULTS: Enzyme-linked immunosorbent assay yielded 1% prevalence which was confirmed to be zero via polymerase chain reaction. A total of 119 (59.5%) of the participants were male, while the mean age was 35.28 ± 13.61 years. Apart from sex and blood reception/donation, there was generally a low rate of exposure to human T-lymphotropic virus-associated risk factors. Meta-analysis revealed pooled prevalence of human T-lymphotropic virus 1 and 2 to be 3% and 0%, respectively, from Nigerian studies. CONCLUSION: This study discovered zero prevalence of human T-lymphotropic virus 1/2 from five major hospitals in Nigeria's capital, exposing the importance of confirmatory assays after positive antibody detection assay results. Meta-analysis highlighted the existence of very few reliable Nigerian studies compared to the demography of the nation. Large-scale epidemiological studies and routine screening of risk populations are therefore needed since Nigeria lies in the region of endemicity.

RESUMEN

Human T-lymphotropic viruses (HTLV) are Deltaretroviruses that infect millions of individuals worldwide via the same transmission routes as HIV. With the aim of exposing the possible re-emergence of HTLV in West Africa since discovery, a systematic review was carried out, focusing on the distribution of the virus types and significance of frequent indeterminate reports, while highlighting the need for mandatory routine blood screening. Capturing relevant data from discovery till date, sources searched were Google Scholar, CrossRef, NCBI (PubMed), MEDLINE, Research Gate, Mendeley, abstracts of Conferences and Proceedings, organization websites and reference lists of selected papers. A total of 2626 references were initially retrieved using search terms: Worldwide prevalence of HTLV, HTLV in Africa, HTLV in West Africa, HTLV subtypes, HTLV 3 and 4 in Africa, HTLV of African origin, HTLV seroindeterminate results, Spread of HTLV. These references were rigorously trimmed down to 76. Although evidence shows that HTLV is still endemic in the region, West Africa lacks recent epidemiological prevalence data. Thorough investigations are needed to ascertain the true cause of indeterminate Western Blot results. It is imperative that routine screening for HTLVs be mandated in West African health care facilities.
