A Identified Antibiotic Might Be a Fierce Weapon in STI Battle

The cheap antibiotic doxycycline has been round for years—however new analysis signifies it could be extra versatile than beforehand recognized. NPR stories that when taken inside 72 hours of condomless intercourse, research have proven that doxy-PEP (that is brief for post-exposure prophylaxis) might defend in opposition to contracting sexually transmitted infections. Particularly, three biggies: chlamydia, gonorrhea, and syphilis. An April study discovered that homosexual and bisexual males and transgender ladies who have been already taking HIV PrEP noticed a 65% drop in new STIs.

She referred to as the findings “an enormous disappointment,” although she cautions that extra examine is required. And there is one other entry on the warning entrance: NPR notes “the implications for antibiotic resistance should be carefully monitored.”

Certainly, a press launch on the April examine famous “the analysis additionally revealed a slight enhance in antibacterial resistance that requires additional exploration.” Nonetheless, “efficient strategies for stopping sexually transmitted infections are badly wanted,” mentioned Nationwide Institute of Allergy and Infectious Ailments director Hugh Auchincloss on the time. CDC estimates put the variety of instances of syphilis, gonorrhea, and chlamydia at 2.5 million in 2021, up from 2.4 million in 2020, with that enhance having “a disproportionate affect amongst MSM (males who’ve intercourse with males) and transgender ladies.” (Learn extra STDs tales.)
