Epidemiology of Extra-Pulmonary Tuberculosis in Israel, 1999-2010 Academic Article uri icon

abstract

  • The Israeli national tuberculosis (TB) surveillance system. To describe the epidemiology of extra-pulmonary tuberculosis (EPTB) in Israel between 1999 and 2010 and identify more susceptible populations. Data were retrieved from the National Tuberculosis Registry and the Israeli Bureau of Statistics. During the study period, 995 EPTB patients were notified, corresponding to 19.6% of all TB cases. The average annual male:female ratio was 0.8, and the human immunodeficiency virus (HIV) infection rate was 5%. Most EPTB affected the lymph nodes (39.8%), pleura (16.9%) and urinary system (11.1%). Most EPTB patients (81.8%) were non-Israeli born. The estimated average annual incidence in Israeli-born citizens, non-Israeli-born citizens and migrant workers was respectively 0.23, 2.2 and 7.5 per 100‚ÄČ000 population. The ratio of non-Israeli-born migrant workers to non-Israeli-born citizens with EPTB decreased from 1:6.3 in 1999 to 1:0.78 in 2010. Culture results were obtained for 624 (62.9%) of all cases. Of these, 41 (6.6%) were resistant to at least one first-line anti-tuberculosis drug and 8 (1.3%) were multidrug-resistant. Treatment success was achieved in 86.5%. Physicians should be aware of the possibility of EPTB in older patients, especially in the non-Israeli-born. Innovative screening procedures should be implemented for migrants from high-burden countries.
