Treatment of Ureaplasma spp Infections
Doxycycline 100 mg orally twice daily for 7 days is the most effective first-line treatment for Ureaplasma spp infections. 1
First-Line Treatment Options
- Doxycycline 100 mg orally twice daily for 7 days is consistently recommended across multiple guidelines and has shown good efficacy in clinical trials 1
- Doxycycline is particularly effective for Ureaplasma urealyticum infections, which is recognized as an etiological agent in non-gonococcal urethritis (NGU) 2
Alternative Treatment Options
- Azithromycin 1.0-1.5 g orally as a single dose is an effective alternative treatment option for Ureaplasma urealyticum infections 1
- Azithromycin has shown efficacy in treating Ureaplasma infections, with studies demonstrating successful eradication of the organism 3, 4
- Other alternative options include:
Management of Persistent Infections
- For patients who fail initial doxycycline therapy, azithromycin 500 mg orally on day 1, followed by 250 mg daily for 4 days is recommended 1
- After azithromycin failure, moxifloxacin 400 mg orally once daily for 7-14 days is recommended 1, 5
- For tetracycline-resistant infections, moxifloxacin 400 mg once daily for 7-14 days is the preferred second-line treatment 5
- Pristinamycin 1 g four times daily for 10 days can be used as a third-line option after moxifloxacin failure, with a cure rate of approximately 75% 5
Diagnostic Considerations
- Perform a validated nucleic acid amplification test (NAAT) on a first-void urine sample or urethral smear before empirical treatment to confirm diagnosis 2
- In patients with mild symptoms, it is advisable to delay treatment until guided by the results of the nucleic acid amplification tests 2
- The role of Ureaplasma spp. in causing urethritis has been debated, with recent data suggesting that U. urealyticum, but not U. parvum, is an etiological agent in NGU 2
Partner Management
- Sexual partners should be evaluated and treated to prevent reinfection 1
- Treatment of partners with last sexual contact within 60 days of diagnosis is recommended 1
- Patients and partners should abstain from sexual intercourse until therapy is completed and symptoms have resolved 1
Follow-Up Recommendations
- Patients should return for evaluation if symptoms persist or recur after completing therapy 1
- Objective signs of urethritis should be present before initiating additional antimicrobial therapy 1
Special Considerations
- In pregnancy, Ureaplasma infections have been associated with adverse outcomes including preterm birth 6
- Maternal azithromycin therapy has shown promise in eradicating Ureaplasma from amniotic fluid and preventing advanced fetal lung injury in primate models 4, 7
- HIV-infected patients should receive the same treatment regimens as HIV-negative patients 1
