Fasting blood glucose profile of tuberculosis patients in Port Harcourt, Nigeria Inumanye N Ojule, Arinze I Opara Port Harcourt Medical Journal 2019 13(1):26-31 Background: The inter-relationship between tuberculosis (TB) and diabetes mellitus (DM) continues to trigger global interest, especially due to increasing prevalence of TB, propelled largely by the HIV epidemic and almost on an equal scale by the increasing incidence of diabetes worldwide, especially in the developing countries. Aim: The aim of this study is to determine the fasting blood glucose (FBG) profile of TB patients in Port Harcourt, Rivers State, Nigeria. Methods: A facility based cross sectional study. A total of 225 adult patients on intensive phase treatment for TB at the two facilities were recruited into the study. Purposive sampling was used to recruit participants into the study in that all the consecutive patients newly diagnosed and attending the clinics during this period were recruited. A semi-structured questionnaire was administered to all participants for medical and socio-demographic data. FBG estimation was done for all the study participants after 8 h of overnight fast using a standardised glucometer. The World Health Organisation criteria were used to classify the study participants into normal, impaired fasting glucose (IFG) and frank DM. Data analysis was carried out using the Statistical Package for the Social Sciences Version. 18. Results: About 5.3% of the participants already knew they were diabetic. The prevalence of newly diagnosed frank diabetes was 8.6%. We obtained prevalence of 15.5% for IFG among the study participants. Conclusion: Our findings confirm a high prevalence of IFG and DM among TB patients in our locality.
