Initial Treatment Approach for a 30-Year-Old Female with Proctitis

For a 30-year-old female with proctitis, the initial treatment should be ceftriaxone 250 mg IM in a single dose PLUS doxycycline 100 mg orally twice a day for 7 days, while awaiting diagnostic test results. 1, 2

Diagnostic Approach

Before initiating treatment, the following diagnostic steps should be performed:

1. Anoscopic examination to evaluate for:

   • Anorectal exudate
   • Mucosal ulceration
   • Bloody discharge
   • Perianal ulcers

2. Laboratory testing for common infectious causes:

   • Gram-stained smear of anorectal exudate to detect polymorphonuclear leukocytes
   • NAAT or culture for Neisseria gonorrhoeae
   • NAAT for Chlamydia trachomatis
   • PCR or culture for Herpes Simplex Virus (HSV)
   • Testing for Treponema pallidum (syphilis serology)
   • If C. trachomatis is positive, perform PCR for lymphogranuloma venereum (LGV)

Treatment Algorithm

Step 1: Empiric Treatment

If any of the following are present:

• Anorectal exudate
• Polymorphonuclear leukocytes on Gram stain
• Clinical presentation consistent with acute proctitis in a patient with history of receptive anal intercourse
• Anoscopy or Gram stain unavailable but symptoms suggest proctitis

Initiate empiric therapy:

• Ceftriaxone 250 mg IM (single dose) PLUS
• Doxycycline 100 mg orally twice daily for 7 days 1, 2

Step 2: Modify Treatment Based on Clinical Findings

If bloody discharge, perianal ulcers, or mucosal ulcers are present AND either:

• Positive rectal chlamydia NAAT, or
• HIV infection

Then:

• Extend doxycycline treatment to 3 weeks total (100 mg twice daily) for presumptive LGV treatment 1, 2

If painful perianal ulcers are present:

• Add treatment for genital herpes (acyclovir, valacyclovir, or famciclovir) 1

Step 3: Adjust Treatment Based on Test Results

Once specific pathogens are identified, tailor treatment accordingly:

• For confirmed gonorrhea: Continue with completed ceftriaxone dose
• For confirmed chlamydia: Complete 7-day course of doxycycline
• For confirmed LGV: Complete 3-week course of doxycycline
• For confirmed HSV: Complete antiviral course

Additional Management Considerations

1. Partner management:

   • Sexual partners from the past 60 days should be evaluated, tested, and treated presumptively 1, 2
   • Both patient and partners should abstain from sexual intercourse until treatment completion and symptom resolution

2. Follow-up testing:

   • For proctitis associated with gonorrhea or chlamydia, perform retesting 3 months after treatment 1
   • All patients with acute proctitis should be tested for HIV and syphilis 1, 2

3. Non-infectious causes:

   • If infectious workup is negative, consider inflammatory bowel disease, particularly ulcerative proctitis
   • For ulcerative proctitis, topical mesalamine (5-ASA) suppository 1g once daily is the first-line treatment 2

Common Pitfalls to Avoid

1. Missing co-infections: Multiple pathogens may be present simultaneously
2. Inadequate testing: Failure to test for all common pathogens can lead to incomplete treatment
3. Insufficient partner management: Not treating partners increases risk of reinfection
4. Confusing infectious and inflammatory causes: Distinguish between infectious proctitis and inflammatory bowel disease
5. Overlooking HIV testing: All patients with proctitis should be tested for HIV

By following this systematic approach to diagnosis and treatment, clinicians can effectively manage proctitis in young adult patients while minimizing complications and preventing transmission.
