Screening program for latent tuberculosis infection in asylum seekers - a single center experience in Pavia, Italy.

Abstract

The management of Latent Tuberculosis Infection is crucial in fighting Tuberculosis worldwide, and particularly in low incidence European Countries. While guidelines for the management of Tuberculosis in newly arrived immigrants have been issued by the European Center for Disease Control and Prevention and by the National Health Authorities in Italy, these are not widely implemented yet at local level. We report our program for the screening of Latent Tuberculosis Infection and active Tuberculosis in asylum seekers, jointly implemented by Public Health Authorities and the Infectious Diseases Department of a tertiary care, teaching hospital in Northern Italy. We reviewed records of the asylum seekers who were screened at our center via Tuberculin Skin Test and/or Interferon Gamma Release Assay plus chest X-ray and either treated with Isoniazid Preventive Treatment or for active Tuberculosis Disease in case of positive results. We screened 726 migrants, mostly males (97.3%) and from Sub-Saharan Africa (82.2%) and found a high adherence rate for both screening (98.2%) and Isoniazid Preventive Treatment (90.1%). In addition, we found seven cases of active Tuberculosis. Latent Tuberculosis Infection screening and treatment proved feasible in our program, which should be systematically implemented in asylum seekers reaching Europe.
