[Miliary tuberculosis]

Abstract

Introduction: Tuberculosis miliary is a severe and rare form of tuberculosis. It is often due to a haematogenous spread of the bacillus of Koch and represents less than 2 % of tuberculosis.

Patients and methods: We conducted a retrospective study of 81 cases of tuberculous miliary collected at the Department of respiratory diseases of the Ibn Rochd university hospital in Casablanca between September 2003 and November 2016.

Results: A female predominance was noted with 58 % of the cases. The average age was 36 years. The history of tuberculosis was found in eight cases and tuberculous tuberculosis in eleven cases, postpartum in five cases, diabetes in three cases and trisomy 21 in one case. The clinical picture was dominated by altered general status in all cases, and fever in 69 cases (86 %). Chest x-ray showed a miliary aspect in all cases, cardiomegaly in two cases, pyopneumothorax in three cases, and opacities excavated in five other cases. The intradermal tuberculin reaction, performed in all cases, was positive in 26 cases, and sputum oscillations were positive in 21 cases. The dissemination report found cerebromeningeal involvement in nine cases, with cerebral tuberculomas in five cases, pericarditis in four cases, mediastinal and peripheral adenopathies in nine cases each. Bouchut tubercles were found in nine cases. Antibacillary therapy was started as a matter of urgency, according to the national TB control program with the old regimen (2SHRZ/7RH) and the new regimen (2RHZEb/7RH) in all cases. The outcome was good in 55 cases (68.9 %), 17 patients were lost to follow-up, and 11 deaths were reported.

Conclusion: We insist on this work on the severity of the tuberculous miliary and the need for early and urgent therapeutic management.
