Effectiveness and safety of a modified short-term regimen of antimycobacterial therapy to treat rifampicin-resistant tuberculosis in elderly patients with concomitant diabetes (a clinical case)

Abstract

Aim. To analyze the effectiveness and safety of a modified short-term regimen (mSTR) of antimycobacterial therapy (AMBT) for rifampicin-resistant tuberculosis (RR-TB) in a 71-year-old patient with type 2 diabetes mellitus (T2DM) on the clinical case example of own observation. Materials and methods. A clinical case from own observation of the patient who was treated at the clinical base of the Department of Phthisiology and Pulmonology of Zaporizhzhia State Medical University – Pulmonary Tuberculosis Department No. 2 of the Communal Non-profit Organization “Zaporizhzhia Regional Phthisio-Pulmonology Clinical Treatment and Diagnostic Center” is presented. Results. The presented case demonstrates the high safety and efficacy of all oral mSTR, including Lfx-Bdq-Lzd-Cfz-Cs, in the elderly person with RR-TB and concomitant decompensated T2DM who was smear-negative after 4 months as a result of treatment with 9-month mSTR AMBT (Lfx, Bdq, Lzd, Cfz, Сs). Positive radiological dynamics were observed all the time and residual changes in the lungs after tuberculosis were diagnosed at the end of the treatment course. These results complement indications for the use of mSTR, including Lfx-Bdq-Lzd-Cfz-Cs, in RR-TB patients. Conclusions. mSTR AMBT (Lfx, Bdq, Lzd, Cfz, Сs) is effective and safe in elderly patients with RR-TB and concomitant decompensated type 2 diabetes mellitus when adequate treatment of diabetes and timely correction of antimycobacterial drug side effects are undertaken.
