BACKGROUND: : Taiwan is an area with moderate to high incidence of Mycobacterium tuberculosis infection. The risk of M tuberculosis infection in transplantation recipients is considered to be significant. Our aim in this study was to investigate the clinical spectrums of M tuberculosis-infected transplantation recipients in a southeast Asian country, Taiwan. METHODS: : We retrospectively analyzed the demographic data, clinical features, treatment, and outcome of M tuberculosis infection in kidney, heart, and liver transplant recipients from May 1996 to April 2005 at the National Taiwan University Hospital. RESULTS: : Fifteen patients who had received solid organ transplantation developed tuberculosis (kidney = 6, heart = 7, liver = 2). The median duration from transplantation to diagnosis of tuberculosis was 31 months. The cumulative incidence of post-transplantation tuberculosis was 2.0% (15/760), ie, approximately 3 times that of the general population. Ten patients (66.7%) had pulmonary tuberculosis, 1 (6.7%) had extrapulmonary tuberculosis, and 4 (26.7%) had disseminated tuberculosis. Nine patients completed the anti-tuberculosis treatment; the median treatment duration was 12 months (pulmonary: 9 months; extrapulmonary: 13.5 months). No treatment failure was noted in patients receiving the complete treatment course. The graft failure and mortality rates of post-transplantation tuberculosis were 13.3% each (2/15). The tuberculosis-associated mortality rate was 6.7% (1/15). CONCLUSIONS: : Cumulative incidence of tuberculosis was slightly higher in transplant recipients than in the general population in Taiwan. Conventional 4-combined anti-tuberculosis regimen for 12 months can treat the potentially fatal infection successfully in post-transplantation tuberculosis patients without recurrence.
