What is the appropriate treatment and management plan for a patient with confirmed uncomplicated urogenital Chlamydia and Gonorrhoea infections, presenting with worsening dysuria, who has had recent sexual contact with a third party and has limited access to medical services while on their honeymoon?

Treatment and Management of Confirmed Urogenital Chlamydia and Gonorrhea with Worsening Dysuria

Immediate Treatment Recommendation

This patient requires immediate dual therapy with ceftriaxone 500 mg IM as a single dose PLUS doxycycline 100 mg orally twice daily for 7 days to treat both confirmed gonorrhea and chlamydia infections. 1, 2

The plan documented (ceftriaxone 500 mg IM stat plus azithromycin 1 g PO stat) is acceptable but not optimal—doxycycline is now preferred over azithromycin for chlamydia treatment due to antimicrobial stewardship concerns and increasing azithromycin resistance. 1, 2

Treatment Regimen Details

For Gonorrhea

• Ceftriaxone 500 mg IM as a single dose is the current CDC-recommended treatment for uncomplicated urogenital, anorectal, and pharyngeal gonorrhea. 1, 2
• The 2020 CDC update increased the dose from 250 mg to 500 mg due to ongoing antimicrobial resistance concerns. 1
• Ceftriaxone must be administered intramuscularly—the patient must present to urgent care or GP for injection administration. 3

For Chlamydia

• Doxycycline 100 mg orally twice daily for 7 days is the preferred first-line treatment, with 98% efficacy. 4, 2
• Azithromycin 1 g orally as a single dose is an acceptable alternative (97% efficacy) when compliance with a 7-day regimen is questionable, which may apply in this honeymoon scenario with limited medical access. 4, 2
• The documented plan using azithromycin is reasonable given the patient's travel circumstances and ensures directly observed single-dose therapy. 4

Why Dual Therapy is Essential

• Coinfection rates between gonorrhea and chlamydia range from 20-40% in high-prevalence populations. 5, 6
• Treating only gonorrhea when chlamydia is present leads to persistent urethritis and ongoing transmission. 5
• Ceftriaxone has no activity against C. trachomatis, making concurrent chlamydia treatment mandatory. 3, 5

---

Sexual Activity Restrictions

The patient must abstain from ALL sexual intercourse for 7 days after initiating treatment AND until all symptoms have completely resolved. 4, 5

This applies regardless of whether single-dose or multi-day therapy is used. 4

Partner Management (Critical Priority)

Immediate Partner Treatment

• The partner must receive empirical treatment for BOTH gonorrhea and chlamydia immediately, without waiting for test results. 7, 5
• All sexual partners within the preceding 60 days (including the "third party" from the first night of the honeymoon) must be evaluated, tested, and empirically treated. 8, 5, 7
• If the last sexual contact was >60 days before diagnosis, the most recent partner still requires treatment. 8, 5

Expedited Partner Therapy Considerations

• Given the honeymoon location with limited medical access, expedited partner therapy (patient-delivered medication or prescription) is an appropriate option for heterosexual partners. 9, 8
• The partner should receive the same dual therapy regimen: ceftriaxone 500 mg IM plus either doxycycline or azithromycin. 7, 5
• Written treatment instructions and counseling materials must accompany any expedited therapy. 9
• Partners should be strongly encouraged to seek in-person medical evaluation for additional STI screening (HIV, syphilis) as soon as possible. 9, 7

Critical Pitfall to Avoid

• Do NOT assume partners were treated based on patient report alone—directly verify treatment or use expedited partner therapy strategies. 4
• Failure to treat partners is the primary cause of reinfection, which occurs in up to 20% of cases. 4, 8

Follow-Up Testing Requirements

Test of Cure

• Test of cure is NOT recommended for non-pregnant patients treated with recommended regimens who become asymptomatic. 4, 2
• Testing before 3 weeks post-treatment is unreliable due to false-positive results from dead organisms. 4
• Test of cure is only indicated if: therapeutic compliance is questionable, symptoms persist, or reinfection is suspected. 4

Reinfection Screening (Mandatory)

• Repeat testing for BOTH gonorrhea and chlamydia is mandatory at 3 months post-treatment, regardless of whether partners were reportedly treated. 4, 5, 2
• This is distinct from test of cure—it screens for reinfection, which carries elevated risk for pelvic inflammatory disease and complications. 4
• If the patient cannot return at 3 months, retest at the next clinical visit within 12 months. 8

Repeat HIV and Syphilis Serology

• Repeat HIV and syphilis testing at appropriate window periods (typically 3 months) is essential, given the recent new sexual exposure. 7, 6
• The current negative results do not exclude recent infection during the window period. 7

Management of Persistent Symptoms

If Dysuria Persists After Treatment

• Evaluate for Mycoplasma genitalium using NAAT on first-void urine or urethral swab, as this organism causes doxycycline-resistant urethritis. 4, 6
• The patient's pathology already shows M. genitalium was not detected, which is reassuring. [@patient case@]
• If symptoms persist despite negative M. genitalium testing, perform culture for N. gonorrhoeae with antimicrobial susceptibility testing. 8

Treatment for M. genitalium (if detected)

• Moxifloxacin 400 mg orally once daily for 7 days is highly effective, particularly for macrolide-resistant strains. 4, 6

Critical Pitfall to Avoid

• Do NOT retreat based on symptoms alone without documenting objective signs of urethral inflammation or laboratory evidence of persistent infection. 4
• Most "treatment failures" are actually reinfections from untreated partners. 8

Safety Netting and Red Flags

The patient must present urgently if any of the following develop:

• Fever (suggests ascending infection/pyelonephritis)
• Flank pain (suggests pyelonephritis)
• Pelvic pain (suggests pelvic inflammatory disease)
• Vomiting or systemic symptoms
• Worsening dysuria despite treatment [@patient case@]

These symptoms would indicate progression to complicated infection requiring hospitalization and IV antibiotics. [@patient case@]

---

Additional STI Screening Completed

The patient's comprehensive STI screening shows:

• HIV 1/2 Ag/Ab: Not detected (repeat at 3 months required) 7
• Syphilis: Non-reactive (repeat at 3 months required) 7
• Hepatitis B surface antigen: Negative [@patient case@]
• Hepatitis C antibody: Negative [@patient case@]
• Hepatitis A antibodies: Detected (indicates immunity, no action needed) [@patient case@]

Practical Implementation Given Limited Medical Access

Immediate Actions

1. Arrange urgent care or GP visit for ceftriaxone 500 mg IM injection as soon as possible—this cannot be delayed. 3, 1
2. Ensure azithromycin 1 g is taken as directly observed therapy (already appropriate given travel circumstances). 4
3. Provide written partner treatment instructions and expedited partner therapy prescriptions/medications if partners cannot access care immediately. 9

Upon Return from Travel

1. Schedule test of cure at 3 months for both gonorrhea and chlamydia 4, 2
2. Repeat HIV and syphilis serology at 3 months 7
3. Ensure all partners have been treated and tested 5, 7

Documentation and Counseling Points

Key counseling messages delivered:

• No sexual contact until 7 days after treatment initiation AND complete symptom resolution 4, 5
• Partner notification and treatment is mandatory to prevent reinfection 5, 7
• Return for repeat testing at 3 months is not optional—it screens for reinfection which increases complication risk 4
• Hepatitis A immunity is present (no concern) [@patient case@]
• Current HIV/syphilis results are negative but repeat testing is required due to window period 7
