In 1987-1992 in Prague drug resistance of M. tuberculosis to four standard antituberculotics (isoniazide, streptomycin, rifampicin, ethambutol) was recorded in 39 patients, i.e. in 1.5-5% of patients with bacillary tuberculosis. Initial resistance was found in 25, secondary resistance in 13 subjects, in one patient both types of resistance were observed. In both groups men and patients born before 1941 predominated. In patients with initial resistance findings rated as small or medium-sized predominated, while in secondary resistance half the findings were medium-sized or extensive; an extrapulmonary form was recorded in one female patient. In the group of patients with an initially resistant M. tuberculosis monoresistant strains predominated and the highest ratio was accounted for by strains resistant to isoniazide; in patients with secondary resistance strains with combined resistance to two or more drugs predominated, however in all instances a combination of isoniazide with other antituberculotics was involved. With regard to the changing epidemiological situation as regards tuberculosis (in particular the arrested decline of the incidence of bacillary tuberculosis and the increase of drug resistance of M. tuberculosis), the authors recommend further monitoring and epidemiological analysis of the incidence of strains with initial and secondary resistance, systematic external checks of laboratory technique used for testing the sensitivity to antituberculotics and its centralization as well as the introduction of analyses of restrictive fragments of the DNA genome (RFLP method) to monitor the spread of tuberculous mycobacteria in the population. |
