Introduction: Endometriosis and pelvic inflammatory disease (PID) are gynecological conditions affecting women of reproductive age and causing pain symptoms. The symptoms caused by these conditions are similar; thus, the differential diagnosis may be challenging. The treatment of these conditions is very different because PID is treated with antibiotic therapy, while endometriosis is treated with hormonal therapies suppressing estrogen levels.
Areas covered: A narrative review was conducted through a comprehensive literature search on endometriosis and PID. The search strategy incorporated relevant keywords and MeSH terms related to these topics.
Expert opinion: The antibiotics used to manage PID have high efficacy and safety profiles. Commonly prescribed regimens include a combination of ceftriaxone, doxycycline, and metronidazole. These antibiotics are generally well-tolerated, with most adverse effects being mild and manageable (gastrointestinal disturbances or hypersensitivity reactions). Hormonal therapies are a cornerstone in the management of endometriosis; they include combined oral contraceptives (COCs), progestins, gonadotropin-releasing hormone (GnRH) agonists, and antagonists. COCs and progestins are generally well-tolerated with a favorable safety profile, though they may cause side effects (breakthrough bleeding and mood changes). Oral GnRH antagonists have emerged as a noteworthy option, offering partial estrogen suppression and thereby overcoming the limitations associated with previously used GnRH agonists.
