Abstract

Introduction. The experience of domestic phthisiatry, which has been using bedaquiline for more than 10 years, testifies to the efficacy and safety of the drug for the treatment of drug-resistant forms of tuberculosis. At the present stage, the evaluation of the effect and safety of bedaquiline in the postoperative stage of chemotherapy, including patients with HIV/tuberculosis co-infection, becomes the most relevant.Aim. To evaluate the results of bedaquiline application in the postoperative stage of complex tuberculosis therapy.Materials and methods. Results of a retrospective study of medical records of 57 patients. The inclusion criterion was the surgery performed for tuberculosis and the presence of bedaquiline in the postoperative chemotherapy regimen. Frequency of tuberculosis progression 1 month after surgery was evaluated as an efficacy criterion. The frequency of QTc interval prolongation with clinical manifestations, frequency and nature of hepatotoxic reactions were evaluated as the drug safety criterion.Results. In the absolute majority of patients – 54 (94.7%) postoperative period, during which bedaquiline was used, proceeded without complications. Cases of tuberculosis progression were observed only in patients with severe concomitant diseases. Undesirable side effects on bedaquiline were observed in 9 (15.8%) patients, the absolute majority of patients resumed taking the drug in full after drug correction. The average duration of bedaquiline prescription was 282 ± 5 doses.Conclusions. The use of bedaquiline in the postoperative period increases the effectiveness of complex therapy and prevents progression of tuberculosis and according to our data should be regarded as safe. Administration of bedaquiline in patients with HIV/tuberculosis co-infection also contributes to the positive result of the therapy. Repeated courses of bedaquiline after surgical intervention, including in patients with HIV/tuberculosis co-infection, prevent progression of tuberculosis in the postoperative period. The tolerability of the bedaquiline-containing regimen in this category of patients, including long courses of more than 24 weeks, was assessed as quite satisfactory.
