An AIDS patient with immune reconstitution inflammatory syndrome due to pulmonary Mycobacterium kansasii infection during antiretroviral therapy

Abstract

After the recovery of pneumocystis pneumonia, amebiasis, and cytomegalovirus duodenal ulcer in a patient with AIDS, antiretroviral therapy was initiated. Fever was first noted on the 11th day of administration of the highly active antiretroviral therapy (HAART), and chest radiography showed infiltration into the right lower lobe of the lung on the 19th day. Bronchoscopy was performed, with a tentative diagnosis of pulmonary tuberculosis, but Mycobacterium kansasii was eventually identified. M. kansasii may also be a pathogenic organism causing immune reconstitution inflammatory syndrome.
