AbstractThe aim of this study was to explore the existence of vitamin D deficiency (VDD) in tuberculosis (TB) patients living in Africa and to identify its predictor variables. PRISMA guidelines and checklists were used. The sources of the data were Medline/PubMed, Web of Science, Scopus, and Google Scholar databases. We identified 23 articles, of which 15 reported the status of vitamin D in TB with TB. The definition of serum vitamin D status was summarized as severe, deficient, and insufficient when the concentration of 25-hydroxyvitamin (OH)-D ≤25, ≤50, and ≤75 nmol/L, respectively. The reports showed that up to 88.9% and 96.3% of patients with TB tested by radioimmunoassay had VDD and vitamin D insufficiency, respectively. Statistically significant variables such as lack of sun exposure, inadequate dietary intake, season, clothing, comorbidities, low body mass index, age, skin pigmentation, use of antiretroviral therapy and anti-TB drugs, and socioeconomic status were identified as the main predictor variables of vitamin D status. VDD and vitamin D insufficiency were highly prevalent in TB patients in Africa. Further case-control studies are warranted to clarify the cause-effect relationship between vitamin D and TB and thereby, design valuable strategies to manage VDD among TB patients in Africa.Copyright © 2015 Elsevier Inc.
