IUDs and colonization or infection with Actinomyces

Area of Science:

• Gynecology
• Infectious Diseases
• Microbiology

Background:

• Pelvic actinomycosis is an extremely rare condition associated with prolonged intrauterine device (IUD) usage.
• Diagnosis is often delayed due to its rarity, typically requiring surgical intervention.
• Penicillin therapy, though lengthy, can be highly effective for treatment.

Purpose of the Study:

• To review the occurrence and management of pelvic actinomycosis in IUD users.
• To assess the clinical significance of Actinomyces-like organisms detected on Pap smears in asymptomatic women.

Main Methods:

• Review of case reports on pelvic actinomycosis in women using IUDs.
• Analysis of the prevalence and prognostic value of Actinomyces-like organisms on Pap tests.

Main Results:

• The precise risk of actinomycosis from IUD use cannot be quantified.
• Approximately 7% of IUD users may have Actinomyces-like organisms on Pap tests.
• This finding has minimal prognostic significance due to low sensitivity, specificity, and positive predictive value.

Conclusions:

• Asymptomatic women with Actinomyces-like organisms on Pap tests do not require antimicrobial treatment or IUD removal.
• Pelvic actinomycosis, though rare, should be considered in women with long-term IUD use, with effective treatment options available.
