Treatment of Proctitis
The recommended treatment for proctitis is ceftriaxone 250 mg IM in a single dose plus doxycycline 100 mg orally twice daily for 7 days, which should be initiated while awaiting test results for patients with acute proctitis who recently practiced receptive anal intercourse and have anorectal exudate or polymorphonuclear leukocytes on Gram stain. 1
Diagnostic Approach
- Patients presenting with proctitis symptoms (anorectal pain, tenesmus, rectal discharge, rectal bleeding) should undergo anoscopy examination to visualize the rectal mucosa and collect specimens 2
- A Gram-stained smear of anorectal exudate should be examined for polymorphonuclear leukocytes 1
- Specific pathogen testing should include:
- If C. trachomatis test is positive, a molecular PCR test for LGV should be performed 1
- All patients with proctitis should be tested for HIV and syphilis 1
Treatment Algorithm
Empiric Treatment
- For patients with acute proctitis of recent onset who have practiced receptive anal intercourse:
Pathogen-Specific Treatment
- For patients with bloody discharge, perianal ulcers, or mucosal ulcers suggestive of LGV:
- Extended treatment with doxycycline 100 mg twice daily orally for a total of 3 weeks 1
- For herpes proctitis:
Follow-Up Recommendations
- Patients should abstain from sexual intercourse until they and their partner(s) have completed treatment and symptoms have resolved 1
- For proctitis associated with gonorrhea or chlamydia, retesting should be performed 3 months after treatment 4, 1
- Monitor for resolution of symptoms including rectal pain, discharge, bleeding, and tenesmus 4
- For persistent symptoms after treatment, evaluate for possible reinfection or treatment failure 4, 2
Partner Management
- Partners who had sexual contact with persons treated for gonorrhea, chlamydia, or LGV within 60 days before symptom onset should be evaluated, tested, and treated presumptively 4, 1
- Both patient and partners should abstain from sexual intercourse until treatment completion and symptom resolution 4
- Follow-up should include verification that all partners have been notified and treated 4
Special Considerations
HIV Co-infection
- Patients with HIV and proctitis require more vigilant follow-up due to risk of more severe disease 4
- Herpes proctitis can be especially severe in HIV-positive patients 3, 1
- Consider more frequent monitoring for those with low immune cell counts 4
Prevention of Recurrence
- Counsel patients about safer sex practices, including consistent condom use for anal intercourse 4
- Consider more frequent STI screening for individuals with ongoing risk factors 4
Common Pitfalls
- Failing to distinguish between infectious proctitis and inflammatory bowel disease can lead to inappropriate treatment 5, 6
- Inadequate partner notification and treatment can lead to reinfection cycles 4
- Overlooking the possibility of multiple concurrent infections 7
- Not considering non-sexually transmitted causes of proctitis such as radiation, ischemia, or inflammatory bowel disease when standard therapy is ineffective 7, 8
