Introduction: We conducted this study to describe the epidemiological and clinical profiles of patients with tuberculosis miliaria and to identify risk factors for the disease. Methodology: This was a case-control study of patients with tuberculosis miliaria (cases) and non-tuberculosis (controls), who were followed between 1 April 2010 and 31 December 2017 at the Friendship Hospital in Bangui. Results: A total of 192 patients were included, including 96 cases of miliaria tuberculosa and 96 controls. The mean age was 40.9±14.1 years [20; 87] for cases compared to 36.6+4.4 years [20; 45] for controls. The sex ratio was 1.2 in cases compared to 1 in controls. The in-hospital frequency of miliary tuberculosis was 15.5% out of a total of 621 tuberculosis cases. The frequency of TB/HIV co-infection was 69.7% (108/155). The median CD4 T cell count was 100/mm3 [1; 646] in cases versus 100/mm² [1; 1079] in controls. The case fatality rate was 35.4% compared to 33.3% for controls. HIV infection was the risk factor for miliary tuberculosis (p = 0.04; OR=2.1[1.1-4.5]). Ko Conclusion: In the Central African Republic, the hospital incidence of tuberculosis miliaria in Bangui is high, and HIV is associated with its occurrence. Effective preventive measures could reduce the incidence of this disease.
