| Summary: | The objective of the study: to develop criteria to evaluate the duration of the intensive phase of chemotherapy for respiratory tuberculosis in children without bacterial excretion and at no risk of multiple and extensive drug resistance of tuberculous mycobacteria.Subjects and methods. Totally, 93 patients with newly diagnosed respiratory tuberculosis without bacterial excretion and at no risk of multiple and extensive drug resistance of tuberculous mycobacteria. Their age varied from 2 to 12 years old. Regimen III was used: the intensive phase – 4 drugs (isoniazid, rifampicin, pyrazinamide, ethambutol – HRZE).Results. The intensive phase lasted for 2 months in 39.8% of cases – the main criteria were achieved (relief of intoxication symptoms, normal blood rates, positive or stable CT changes) after 2 months and there was no indication to extend the duration of it. The intensive phase lasted for 3 months in 37.6% of cases – the main criteria were achieved after 2 months and there was at least one additional indication to extend it (17.2%); and the main criteria were achieved after 3 months and there was no indication to extend the duration of it (20.4%). The intensive phase lasted for more than 3 months (4 to 6 months) in 22.6% of cases – the main criteria were achieved after 3 months and there was at least one additional indication to extend it (12.9%), as well as in the case of failure to achieve the main criteria after 3 months regardless of the presence/absence of additional indications to extend its duration (9.7%).Conclusion. Various combinations of the main criteria and additional indications made the basis for differential approach to determining the duration of the intensive phase of chemotherapy in children with respiratory tuberculosis |
