[Characterization of patients with treatment failure in the Central Tuberculosis Registry].

An analysis was carried out in order to explain the reason of treatment failure in patients with bacteriology confirmed active tuberculosis registered in the Central Tuberculosis Register in the years 1988-1991. The population of patients is whom failure of treatment was observed is older compared with the population of patients in whom the treatment did not fail. The regimens in both groups were similar although the duration of the regimens was shorter in the group in whom tuberculosis was not eradicated (less than 3 months or the treatment duration could not be established). In the chronic sputum positive patients severer cases of tuberculosis were observed more often. Tuberculosis coexistent with other diseases was seen twice more often. The result of therapy in patients with bacteriologically confirmed tuberculosis can be effected by coexistency of tuberculosis and alcoholism.
