  • Title: Incidence of tuberculosis among HIV-positive persons in the Czech Republic between 2000 and 2020.
    Author: Wallenfels J, Malý M.
    Journal: Epidemiol Mikrobiol Imunol; 2022; 71(2):93-101. PubMed ID: 35940863.
    Abstract:
    AIM: The aim is to characterize in more detail the group of HIV-positive persons in the Czech Republic diagnosed with tuberculosis (TB) in 2000-2020. MATERIAL AND METHODS: Data sources were mainly the national online TB register (RTBC), which is part of the information system of the Public Health Service, and the national electronic register of HIV-positive persons (RHIV) maintained by the National Reference Laboratory for HIV/AIDS of the National Institute of Public Health. RESULTS: Of 3,763 TB cases reported to the RHIV since 1985 and 16,212 TB cases reported to the RTBC since 2000, 91 occurred in 88 HIV-positive persons (69 males and 22 females) between 2000 and 2020. Sixty-five (74%) of the 88 HIV-positive persons were foreign born. Twenty-six per cent of TB cases were screened for HIV. The mean age of patients with TB/HIV coinfection was 35 years. The largest number of coinfected persons (35 cases) were from the capital city of Prague. Pulmonary TB was detected in 84 cases. Ninety-two per cent of the TB cases were bacteriologically confirmed, and 10 cases were multidrug-resistant TB. At the time of TB diagnosis, the median CD4+ lymphocyte count was 91.5 cells per mm3 of blood. TB was the most common reason for HIV testing in the analysed cohort (23 cases). The most common mode of HIV transmission was sexual intercourse (heterosexual in 39 cases and homosexual in 13 cases). Treatment success at 12-month follow-up was only recorded in 32% of cases of culture-positive pulmonary TB in HIV-positive patients. CONCLUSIONS: TB/HIV co-infection remains a serious health concern, especially in the foreign-born residents of the Czech Republic. Of foreign-born persons with TB, 42% were tested for HIV over the 21-year study period, with their percentage increasing over the years. Almost 6% of them tested HIV positive. The most relevant finding is that treatment success was only recorded for less than one third of HIV-positive persons with culture-positive pulmonary TB and that every fourth patient with TB/HIV died before or during TB treatment.
