TB or not TB? Difficulties in the Diagnosis of Tuberculosis in HIV-negative Immigrants to Germany.
Background: Immigrants to Germany and their children are at particular risk for tuberculosis (TB). - Methods: 35 Patients (10 male / 25 female aged 2 - 59 years (median 33 years) originating mostly from high incidence countries in Asia (19 (54.3%)) in Africa (14 (40.0%) and East Europe (2 (5.7%)), attended at the Tropical Medicine Unit were analysed. - Results: Primary clinical presentation was most frequently lymphadenitis (13 (37.1%)). Other organs involved included bones (7 (20.0%)), central nervous system (5 (14.3%)), urogenital organs (3 (8.6%)), lung (3 (8.6%)), mediastinum, (2 (5.7%)) and abdomen (2 (5.7%)). ESR was abnormal in 21/28 (75.0%), CRP in 20/35 (57.1%), and protein electrophoresis in 22/26 (84.6%) cases. The tuberculin skin test was strongly positive in all 15 cases where the test had been performed. Tuberculosis interferon gamma release assay (TB-IGRA) was positive in all 35 cases (100%). PCR for nucleic acids of Mycobacterium (M.) tuberculosis complex was positive in only 7/20 (35.0%) cases. M. tuberculosis was identified in 32/35 (91.4%), M. bovis in 2 (5.7%) cases. 1 case was diagnosed clinically. All patients were negative for HIV. Typical histopathology was seen in the 29 cases, where biopsies had been taken. Chest-X-ray did not reveal specific pulmonary lesions in the majority of cases (22/35 (62.9%)). Diagnosis of TB was mostly delayed (4 to 299 weeks, (median 8)). The most frequent primary suspicion was a malignancy (17/35 (48.6%)) while TB was initially suspected in 5 cases only. Diagnosis of TB is impeded by its multifaceted presentation especially in immigrants.[1]References
