A multicenter retrospective electronic health record database evaluation of subjects with Mycoplasma genitalium

Mycoplasma genitalium is a sexually transmitted infection (STI) increasing in prevalence. The recent availability of nucleic acid amplification tests (NAATs) has led to updated diagnostic and treatment guidelines. As medication therapy experts, pharmacists can facilitate appropriate antimicrobial selection and stewardship and optimize best patient-care practices in the setting of M. genitalium infection.

This study aimed to evaluate patient demographics, therapeutic approaches, and complications of patients with laboratory evidence of M. genitalium hypothesizing that younger adolescent females are affected by this organism, receive suboptimal treatment, and have more complications than adults.

This was a retrospective cohort study using TriNetX multicenter electronic health record data of subjects aged 12 years and older with evidence of M. genitalium DNA detected via NAATs. The cohort was divided into 2 age groups: adolescents (12-21 years) and adults (older than 21 years). We evaluated age, sex, race, ethnicity, diagnostic codes, and medication codes.

Our study included 1126 subjects (192 adolescents [17.1%] and 934 adults [82.9%]) who tested positive for M. genitalium. Subjects in the adolescent group had higher odds of being women (2.52 [1.80, 3.54], P < 0.001), having inflammatory diseases of female pelvic organs diagnostic codes (1.51 [1.06, 2.16], P = 0.025), increased odds of azithromycin prescription (1.70 [1.17, 2.48], P = 0.005), and decreased odds of moxifloxacin prescription (0.41 [0.26, 0.64], P < 0.001).

Our study revealed a higher prevalence of M. genitalium infection in adults and adolescents with increased odds of receiving azithromycin and decreased odds of receiving moxifloxacin. Both age groups had decreased odds of receiving doxycycline compared with azithromycin despite guidelines recommending initial empirical antibiotic treatment with doxycycline and growing macrolide resistance. Suboptimal treatment of this infection may lead to lifelong complications. Pharmacists may provide crucial guidance and education to both patients and health care providers regarding appropriate treatment for M. genitalium.
