One patient showed a type 1 leprosy reaction during the first 3 months of treatment of pleural TB and in the other patient, pulmonary TB was diagnosed during the first 3 months of treatment of a type 1 leprosy reaction. Both patients showed normal cellular immune response tests, including those of the interferon-gamma (IFN-γ)/interleukin 12 (IL-12) axis. Although both mycobacterial infections are endemic in developing countries like Brazil, the co-infection has hardly been reported in the last decade. There is no suitable explanation for this observation. The reports on the interaction between the two mycobacteria are highly speculative: some studies suggest that leprosy, especially the anergic form, would predispose to TB, whereas other investigations suggested an antagonism between the two diseases.}, year = {2012}, journal = {The American journal of tropical medicine and hygiene}, month = {2012 Dec 3}, issn = {1476-1645}, url = {http://www.ajtmh.org/content/early/2012/11/29/ajtmh.2012.12-0433.full.pdf}, language = {eng}, }
