Investigation of drug regimens and treatment outcome in patients with Mycobacterium Simiae: a systematic review
Abstract
INTRODUCTION: Mycobacterium simiae (M.simiae), a non-tuberculous mycobacterium (NTM), rare causes infection including localized pulmonary to disseminated disease in immunocompromised patients. An optimal pharmacological management practice has not yet been defined for this infection. This study investigates drug regimens and treatment outcomes in patients with M. simiae to describe different drug regimen with the therapeutic response.
AREAS COVERED: The three databases PubMed, Scopus, and Web of science were systematically searched from June 1994 to June 2021 to retrieve relevant articles. The inclusion criterion included studies, which reported treatment outcomes in patients with M. simiae infections. Treatment success was defined as the achievement of culture conversion, and the improvement of the symptoms and radiologic signs among the patients.
EXPERT OPINION: Data of 223 patients were retrieved from 40 studies. Duration of the treatment regimens used in different studies ranged from 2 to 12 months. The most common treatment regimens administered for M. simiae infection were as follows: clarithromycin, rifampin, ethambutol, moxifloxacin, or ciprofloxacin and amikacin plus cotrimoxazole or pyrazinamide in some regimens. Macrolides, such as clarithromycin, combined with quinolones (such as moxifloxacin) and TMP/SMX, which are used in combination, had the most significant effect on eliminating the pulmonary signs of M. simiae.
