Sponsor's own description

Tuberculous paradoxical reactions (PR) are immune reactions occurring during the course of antituberculous treatment and leading to a worsening of tuberculous symptoms after an initial improvement. This phenomenon has very extensively studied in HIV infected patients where it corresponds to the so called IRIS (immune reconstitution syndrome). However, it laso occurs in non immuno-compromized patients, especially those with extra-pulmonary localization of tuberculosis. The aim of the study is to look for risk factors of paradoxical reaction in non immuno-compromized patients with extra-pulmonary tuberculosis. The investigators will consider clinical, radiological and biological variables, including specific immune and genetic markers. Our secondary goals are to estimate the incidence of PR, describe their natural history; characterize the type of immune response they correspond to, and look for better diagnostic tools.The immunological characterization and the finding of predictive factors of PR, especially the genetic ones will allow a better understanding of biological mechanisms that lead to their occurrence during extra-pulmonary tuberculosis treatment. The establishment of predictive criteria could permit a better surveillance of at risk patients for a rapid treatment, or even a prevention of PR. The establishment of new diagnostic criteria at the time of PR could avoid numerous invasive diagnostic procedures, surgery and/or useless prolongation of antibiotic treatment.
