What is the recommended treatment for Fitz-Hugh Curtis syndrome?

Treatment of Fitz-Hugh-Curtis Syndrome

For mild to moderate Fitz-Hugh-Curtis syndrome, treat with ceftriaxone 250 mg IM as a single dose plus doxycycline 100 mg orally twice daily for 14 days. 1

Outpatient Treatment Regimens

First-line therapy:

• Ceftriaxone 250 mg IM single dose PLUS doxycycline 100 mg orally twice daily for 14 days 1
• This dual therapy targets both Neisseria gonorrhoeae and Chlamydia trachomatis, the two primary causative organisms 1, 2, 3

Alternative outpatient regimen:

• Cefoxitin 2 g IM single dose with probenecid 1 g orally (given concurrently) PLUS doxycycline 100 mg orally twice daily for 14 days 1
• Consider adding metronidazole 500 mg orally twice daily for 14 days if anaerobic coverage is needed 1

Inpatient Treatment for Severe Cases

Hospitalization is indicated when:

• Severe symptoms are present 4
• Diagnostic uncertainty exists 4
• Compliance concerns arise 4
• Pregnancy is present 1

Parenteral regimen options:

• Cefotetan 2 g IV every 12 hours OR cefoxitin 2 g IV every 6 hours PLUS doxycycline 100 mg orally or IV every 12 hours 1
• Alternative: Clindamycin 900 mg IV every 8 hours PLUS gentamicin loading dose 2 mg/kg IV/IM, then 1.5 mg/kg every 8 hours 1

Transition strategy:

• Continue parenteral therapy for 24-48 hours after clinical improvement begins 1, 4
• Switch to oral doxycycline 100 mg twice daily to complete 14 days total therapy 1

Critical Management Considerations

Mandatory chlamydia coverage:

• All patients must receive presumptive treatment for Chlamydia trachomatis unless definitively excluded by testing 4
• C. trachomatis is identified in 89% of Fitz-Hugh-Curtis cases 5

Follow-up requirements:

• Examine patients within 72 hours of starting outpatient therapy to ensure clinical improvement 1
• Retest approximately 3 months after treatment due to high reinfection risk 4

Sexual Partner Management

Partner treatment protocol:

• Examine and treat all sexual partners who had contact with the patient during the 60 days preceding symptom onset 1, 4
• Partners receive the same dual therapy: ceftriaxone 250-500 mg IM single dose plus azithromycin 1 g orally single dose 4
• Both patient and partners must abstain from sexual intercourse until therapy is completed (7 days after single-dose regimens or after completion of 7-day regimens) 1

Special Populations

Pregnancy:

• Hospitalize all pregnant women with suspected Fitz-Hugh-Curtis syndrome due to high maternal morbidity and fetal complication risk 1
• Use ceftriaxone 1 g IM or IV every 24 hours (quinolones and tetracyclines are contraindicated) 1, 4
• Azithromycin 1 g orally provides chlamydia coverage in pregnancy 4

HIV-positive patients:

• Treat with the same regimens as HIV-negative patients 1

Severe cephalosporin allergy:

• Use spectinomycin 2 g IM every 12 hours as alternative parenteral therapy 4

Common Diagnostic Pitfalls

Clinical presentation challenges:

• Right upper quadrant pain mimics acute cholecystitis or pleurisy, leading to frequent misdiagnosis 2, 6
• Pelvic symptoms may be absent or minimal, particularly when chest pain is the presenting complaint 6
• Consider Fitz-Hugh-Curtis syndrome in all sexually active young women with right upper quadrant or right-sided chest pain 5, 6

Diagnostic approach:

• Biphasic CT with arterial and portal phases helps confirm perihepatitis and avoid invasive procedures 5
• Look for perihepatic fluid collections and subcapsular lesions on imaging 7
• Noninvasive diagnosis is preferred since the condition responds well to oral antibiotics 2

Avoid quinolones:

• Do not use ciprofloxacin or levofloxacin empirically due to widespread quinolone-resistant N. gonorrhoeae (resistance exceeds 20% in some populations) 8
