Treatment of Hidradenitis Suppurativa
The treatment of hidradenitis suppurativa should follow a stepwise approach based on disease severity, with topical clindamycin for mild disease, oral antibiotics for moderate disease, and adalimumab for severe or refractory cases. 1, 2
Disease Assessment
- Evaluate disease severity using the Hurley staging system (stages I-III) to guide appropriate treatment selection 2
- Monitor treatment response using the Hidradenitis Suppurativa Clinical Response (HiSCR), which measures reduction in inflammatory lesions 1
- Assess patient-reported outcomes including pain (Visual Analog Scale) and quality of life (Dermatology Life Quality Index) 2
Treatment Algorithm Based on Disease Severity
Mild Disease (Hurley Stage I/mild Stage II)
- First-line therapy: Topical clindamycin 1% solution/gel twice daily for 12 weeks 1
- Alternative first-line therapy: Tetracycline 500 mg twice daily for up to 4 months for more widespread mild disease 1
- For acute, localized flares: Intralesional triamcinolone (10 mg/mL) can provide significant reduction in erythema, edema, suppuration, and pain 1
Moderate Disease (Hurley Stage II)
- First-line therapy: Clindamycin 300 mg twice daily with rifampicin 600 mg once daily (or 300 mg twice daily) for 10-12 weeks 1, 3
- Tetracycline antibiotics (doxycycline, minocycline) have shown efficacy in moderate disease with fewer deep inflammatory lesions 4
- For patients not responding to antibiotics, consider advancing to biologic therapy 1, 2
Severe Disease (Hurley Stage III)
- First-line therapy: Adalimumab (Humira) is FDA-approved for moderate to severe hidradenitis suppurativa in patients 12 years and older 5
- Adalimumab dosing: Initial dose of 160 mg (day 1), followed by 80 mg (day 15), then 40 mg weekly starting at day 29 5
- For patients who fail adalimumab: Consider infliximab 5 mg/kg at weeks 0,2,6, and every 2 months thereafter for 12 weeks 1
Surgical Interventions
- Surgical treatment is often necessary for lasting cure, especially in advanced disease 1
- Options include:
- The width of excision (rather than wound closure technique) influences therapeutic outcome 1
Special Populations
Pediatric Patients
- For children aged 12 years and older with moderate to severe disease: Adalimumab is FDA-approved 5
- For children aged 8 years and older requiring systemic antibiotics: Oral doxycycline is recommended 1
- For adolescent females requiring anti-androgens: Consider spironolactone or combined oral contraceptives 1
Adjunctive Therapies
- Weight loss should be encouraged for patients with obesity 2
- Smoking cessation is important as tobacco use is associated with worse outcomes 2, 6
- Pain management with NSAIDs for symptomatic relief 6
- Appropriate wound care for draining lesions 6
Monitoring and Follow-up
- Assess treatment response using HiSCR, which measures reduction in inflammatory lesions 1, 2
- Monitor for adverse effects, especially with biologics (serious infections, malignancy) 5
- Evaluate quality of life improvement using DLQI 2
Important Considerations and Pitfalls
- Antibiotics in HS are used for both antimicrobial and anti-inflammatory effects 7
- Early intervention is crucial to prevent irreversible skin damage and tunnel formation 8
- Recognize that HS is often associated with comorbidities (metabolic syndrome, inflammatory arthritis, inflammatory bowel disease) that may require additional management 8
- Be aware that non-surgical methods rarely result in lasting cure for advanced disease 1
- For adalimumab, if clinical response is not achieved after 16 weeks, consider alternative treatments 1
