Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects hair follicles, with predilection for intertriginous sites. The prevalence of HS ranges from 0.1% to 2%, with HS significantly affecting the quality of life for patients, with both physical and emotional consequences.

Grading

Hurley staging is recommended to determine therapies. Stage I is classified by recurrent nodules and abscesses with minimal scars. Stage II is classified by one or a limited number of sinuses and/or scarring within a body region. Stage III is classified by multiple or extensive sinuses and/or scarring. The Dermatology Life Quality Index and pain visual analog scale scores can be used in addition to the Hurley staging for management.

Diagnostic testing/comorbidities screening

There is limited evidence for microbiological testing for HS because skin flora is the main bacteria cultured. Patients should be screened for smoking use, diabetes, metabolic syndrome, depression/anxiety, follicular occlusion tetrad, and squamous cell carcinoma. Some studies have suggested an association between the severity of HS and smoking; therefore, smoking cessation is recommended. Patients should also be counseled on weight loss.

Zinc supplementation (90 mg daily) may be helpful. However, there is insufficient evidence for recommendations to avoid diary, brewer’s yeast, friction, deodorant, depilation, or shaving. There is also insufficient data to support vitamin D supplementation.
 

Topical/intralesional therapies

Expert opinion supports the use of chlorhexidine, benzoyl peroxide, or zinc pyrithione. A keratolytic and antiseptic cream such as resorcinol 15% cream may be used but can cause contact dermatitis. Topical clindamycin may decrease pustules formation, but it can increase resistance to Staphylococcus aureus. Triamcinolone intravlesional injections may decrease inflamed HS lesions in the short term.

Systemic antibiotics

Systemic antibiotics have been used for decades to treat HS. Tetracyclines for a 12-week course or long-term maintenance can be used in mild to moderate HS. Clindamycin and rifampin combination can be used as second-line therapy for mild to moderate HS. Moxifloxacin, metronidazole, and rifampin combination can also be considered second-line treatment for moderate to severe disease. Dapsone can be used in patients with Hurley stage I or II for maintenance therapy. Ertapenem IV can be used as a rescue or as bridge therapy for severe disease.

The duration of antibiotics and frequency of use depends on each patient and resistance.

Hormonal agents and retinoids

Although androgens may influence HS, evidence for hormonal agents is limited. Hormonal agents, such as ethinyl estradiol and spironolactone, can be considered for females with mild to moderate HS. Retinoids may be considered as a second- or third-line agent, especially in patients with severe acne and HS.

Immunosuppressants and biologics

Immunosuppressants such as methotrexate and azathioprine provide limited benefit; therefore, they are not recommended. Colchicine with minocycline may provide slight benefit in refractory mild to moderate HS. Cyclosporine may be considered in recalcitrant, severe HS. Systemic corticosteroids can be used short term for acute flares or long term for severe HS.

Biologic therapy is becoming more common and the choice of therapy for moderate to severe HS. Adalimumab is currently the only Food and Drug Administration–approved tumor necrosis factor–inhibitor treatment for HS. Other biologics – including infliximab, anakinra, and ustekinumab – may be effective for HS, but optimal dosing needs to be determined.
 

Pain management

While there are no studies about pain in HS, acute pain management should include topical analgesics and oral nonsteroidal anti-inflammatory drugs. Anticonvulsants such as pregabalin or gabapentin may help with neuropathic pain, and opioids can be considered if there is no improvement with first-line agents.

Surgical management

Recurrent nodules and tunnels can be deroofed or excised. Acute abscesses may be relieved by incision and drainage. Extensive lesions may require wide local scalpel excision, carbon dioxide laser excision, or electrosurgical excision. Surgery alone does not affect the biology of HS; therefore, surgical interventions should be reserved for disease that is not managed by medical therapy.

The bottom line

HS is a chronic inflammatory condition with complex medical management and surgical treatment options. Hurley staging I-III can be used to grade severity and determine therapy. Management of pain, tobacco cessation, weight loss, and mental health are important aspects of HS. Zinc supplementation (90 mg daily) may be helpful. Experts opinion supports the use of chlorhexidine, benzoyl peroxide or zinc pyrithione.

Acute lesions may be managed with short-term oral or intralesional corticosteroids, as well as deroofing or incision and drainage. Moderate-to-severe HS may be managed with systemic antibiotics or biologics and surgical therapy. Adalimumab is the only FDA-approved biologic for treatment of HS.
