Introduction: We set out to determine the seroprevalence of hepatitis B and hepatitis C viruses among human immunodeficiency virus infected individuals and its impact on pattern of presentation. Methodology: A serological study for hepatitis B and hepatitis C viruses was performed on 260 HIV-positive individuals. These patients were tested for the presence of hepatitis B surface antigen and anti-hepatitis C virus (HCV) antibody. Results: Thirty (11.5%) patients tested positive for hepatitis B surface antigen, six (2.3%) tested positive for anti-hepatitis C virus antibody, four (1.5%) were positive for both hepatitis B surface antigen and anti-hepatitis C virus and the overall prevalence was 15.4% . Individuals younger than 40 years of age were more affected, and the odds ratio of a female being co-infected was 1.2, 25% versus 75% p value = 0.03. The prevalence of HIV and hepatitis co-infection rises with age except for hepatitis C. There was no significant difference in the mean levels of liver enzymes (AST, ALT) among the various groups. The groups differ significantly in their mean CD4 count: it was lowest for those coinfected with hepatitis B and hepatitis C; 106 cells/mm 3 , 171 cells/mm 3 for those with HIV alone; and the highest value of 260cells/mm 3 was obtained in those who tested positive for anti-HCV. Scarification marks and multiple blood transfusions were more common among those infected. There was no case of intravenous drug abuse identified. Conclusion: This low frequency of HIV/HCV co-infection is probably due to the uncommon intravenous drug abuse in this population. Coinfection with hepatitis B virus is common among our HIV-infected patients and should be a major consideration in the initiation and choice of therapy.
Proteomics of sweat from active TB patients is a viable approach for biomarker identification, which could be used to develop a nonsputum-based test for detection of active TB.
Background:‘Mai suya’ is a common job in the most northern Nigeria in which there is significant exposures to wood smoke and oil fumes. The respiratory impact of these dual exposures on workers engaged in this work has not been previously documented, hence this study was carried out.Aim:The aim is to study the prevalence, patterns and respiratory function assessment among this group.Subject and Methods:This is a case controlled study involving mai suya and workers who are not exposed to wood smoke and oil fumes in an occupational setting. All consenting mai suya and matched controls were recruited. Both groups underwent an interviewer administered questionnaire followed by on spot spirometric test measuring forced expiratory volume in one second (FEV1), forced vital capacity (FVC), peak expiratory flow rate (PEFR). Results are presented using descriptive statistics. Chi square was used to test for association between respiratory symptoms and the job categories. Student's t-test was used to compare values of continuous variables. Odd ratios were determined for the risk of respiratory symptoms and exposure to wood smoke and oil fumes.Results:Both groups are similar in their demographic characters except in their smoking status, so current smokers were excluded from further analysis. The test group had significantly increased occurrence of chest tightness: 59% (19/32), nasal congestion: 37% (12/32), cough: 32% (10/32), and wheeze: 12% (4/32) compared with the control group, odds ratio (OR) 3.1, 95% confidence interval CI (0.1-5.8), P value 0.04, OR 1.2,95% CI (1.04-1.8), P value = 0.02, OR 0.9 95% CI (0.9-1.4), P value = 0.3, and OR 1.2,95% CI (1-1.3), P value = 0.04, respectively. Occurrences of some respiratory symptoms were associated with duration on the job, while a positive family history of asthma is not associated with increased occurrence of symptoms. The mean (SD) FEV1 and FVC were significantly lower among the test group compared with the control group; 2.5L/s (0.55) versus 3.02L/s (0.51), P value = 0.007 and 2.7L (0.7) versus 3.16L (0.51), P value = 0.04.Conclusion:Mai suya’ have increased risk of respiratory symptoms and altered pulmonary functions. There is a need for protective equipment and periodic evaluation.
Background: Increased morbidity and mortality of tuberculosis have been blamed on neglect of the human dimension of tuberculosis control. One of such factors included in human dimension is non-compliance, a behavioural parameter, which has led to the emergence of multi-drug resistant tuberculosis, and poor treatment outcome. Objective: To explore the impact of directly observed therapy (DOT) on compliance and the factors influencing it. Design: A retrospective study. Setting: Chest clinic of Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. Methods: Directly observed therapy (DOT) was employed. Records of the socio-demographic characteristics, treatment categories, complications developed, results of investigations, level of compliance and treatment outcome for the patients were kept. The data for the patients seen between May 1996 and April 1997 were retrieved and analysed. Those that complied were compared with those that did not comply. Results: One hundred and ninety nine patients comprising ninety one males and 108 females, were seen during the period .They were mostly between the ages of 16 years and 45 years(mean ± SD = 31.7±14.98). One hundred and fifty eight (73%) complied and all of them were cured. The only factor that significantly influenced rate of compliance was proximity to the chest clinic. Conclusion: DOT improves the rate of compliance. No socio-demographic factors considered significantly influenced the rate of compliance under DOT, and as such they are not reliable predictive factors. Locating chest units in the existing primary health care facilities will improve the rate of compliance with antituberculosis therapy. More attention should be paid to behavioural aspect of tuberculosis control.
Background: Chronic Obstructive Pulmonary Disease (COPD) is a multi-systemic and progressive disease. However the determinants of its impact on health related quality of life are not well-studied or understood in Nigeria. Objectives: To assess the determinants of health related quality of life in COPD Methods: Patients with stable COPD were recruited consecutively from the outpatient clinics of a university hospital. Health Related Quality of Life (HRQL) was assessed using the St. George's Respiratory Questionnaire (SGRQ) and the Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC) were measured by a vitalograph spirometer. Results: Fifty patients were recruited for this study (male= 60%). The mean (SD) age was 69 (9) years. The overall mean (SD) SGRQ scores was 45.9 (26.5), 50.6 (29.2), 29.7 (19.9), 38.8 (22.0) for the symptom, activity, impact and total scores respectively. After adjusting for age, sex and smoking, self-reported breathlessness independently predicted on average 25.2, 36.8, 13.65 and 22.9 points increase in SGRQ symptom, activity, impact and total scores respectively. Self-reported weight loss predicted 12.2 points increase in the impact subscale. Conclusions: Self-reported breathlessness and weight loss are independent predictors of low HRQL score in COPD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
