Clinical case of failure of josamycin in a patient with urethritis caused by Mycoplasma genitalium

Abstract

Mycoplasma genitalium is one of the obligate pathogens that cause sexually transmitted diseases. To detect this pathogen in routine practice, only molecular genetic methods are used that are also used to identify the resistance of MGE to antibiotics. The first-line drugs for the treatment of diseases caused by MGE, are tetracycline and macrolides. In recent years, many countries have increasingly recorded cases of unsuccessful therapy macrolides. Mutations that confer antibiotic resistance to macrolides for Mycoplasm genitalium are concentrated in nucleotide positions 2058 and 2059 in region V of the 23S rRNA gene. Unknown status of macrolide resistance M. genitalium can lead to the development of a persistent infection. We describe the first reported cases of clinical josamycin treatment failure from patient with ure - thritis. The reason for antibiotic resistance was a mutation in the 23S rRNA of MGE as a nucleotide substitution in position A2058G.

The rates of mutations associated with macrolide resistance in Mycoplasma genitalium among patients with non-gonococcal sexually transmitted infections in Smolensk and Tula

“…В зарубежных статьях неоднократно упоминалось о случаях безрезультатного лечения макролидами [17,21,22]. Клинический неуспех терапии джозамицином у пациентов с НГУ, вызванными M. genitalium, также был описан и в российских публикациях [18][19][20].…”
