Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition characterized by recurrent, painful nodules, abscesses, and sinus tracts primarily affecting areas with apocrine sweat glands, such as the axillae, groin, and under the breasts. Despite its prevalence, the exact cause of HS remains unknown, complicating treatment approaches. This article aims to provide a detailed overview of the available treatments for HS, spanning medical, surgical, and lifestyle interventions.
Medical Treatments for Hidradenitis Suppurativa
Antibiotics
Antibiotics are often the first line of treatment for HS due to their anti-inflammatory properties and ability to target secondary bacterial infections that exacerbate the condition. They can be administered topically or orally, depending on the severity of the disease.
1. Topical Antibiotics: Clindamycin is a commonly prescribed topical antibiotic. Studies have shown that applying clindamycin 1% solution twice daily can reduce inflammation and the number of lesions. It is generally recommended for mild cases of HS.
2. Oral Antibiotics: For more severe or widespread HS, oral antibiotics like tetracyclines (doxycycline, minocycline) are frequently used. Rifampin, often combined with clindamycin, has also been effective. These antibiotics help control bacterial growth and reduce inflammation, though they are usually prescribed for a limited duration to prevent antibiotic resistance.
Biologics
Biologic therapies have revolutionized the treatment landscape for HS, particularly for patients with moderate to severe disease unresponsive to conventional therapies. Biologics target specific components of the immune system that drive inflammation.
1. TNF-alpha Inhibitors: Adalimumab is the only biologic approved by the FDA specifically for HS. It works by inhibiting tumor necrosis factor-alpha (TNF-alpha), a cytokine involved in systemic inflammation. Clinical trials have demonstrated that adalimumab significantly reduces the number of abscesses and inflammatory nodules in HS patients.
2. Other Biologics: While not specifically approved for HS, other biologics such as infliximab, etanercept, and ustekinumab have shown promise in off-label use. These drugs target various pathways in the immune system and have been effective in reducing HS symptoms in clinical studies.
Hormonal Therapy
Hormonal therapies are considered for HS patients whose disease is influenced by hormonal factors, particularly women. These treatments aim to reduce the activity of androgens, which can exacerbate HS.
1. Oral Contraceptives: Combination oral contraceptives containing estrogen and progestin can help regulate hormonal fluctuations that might trigger HS flares.
2, Anti-androgens: Spironolactone and finasteride are medications that reduce androgen levels and have been found beneficial in managing HS, particularly in women.
Retinoids
Retinoids, derived from vitamin A, have anti-inflammatory and keratolytic effects, making them useful in treating various dermatological conditions, including HS.
Oral Retinoids: Isotretinoin, commonly used for severe acne, has been used off-label for HS. However, its effectiveness in HS is variable, and it is generally reserved for patients who do not respond to other treatments due to its potential side effects.
Immunosuppressants
Immunosuppressive drugs can be effective in severe HS cases that do not respond to other treatments. These drugs work by dampening the immune response that contributes to the inflammation and lesions characteristic of HS.
Cyclosporine: This immunosuppressant has shown efficacy in treating severe HS by reducing immune system activity, though it is associated with significant side effects and requires close monitoring.
Surgical Treatments for Hidradenitis Suppurativa
Surgical intervention is often necessary for patients with advanced HS or those who do not respond to medical treatments. The type and extent of surgery depend on the severity and location of the lesions.
Incision and Drainage
This minor surgical procedure involves making a small cut in the skin to drain abscesses. While it provides immediate relief from pain and pressure, it is generally considered a temporary solution as it does not prevent recurrence.
Wide Excision
Wide excision involves removing the affected skin and underlying tissue, and is often the most definitive surgical treatment for HS. This procedure aims to remove all diseased tissue to prevent recurrence. The resulting wounds may be left to heal naturally or closed with skin grafts or flaps.
Laser Surgery
Laser treatments have gained popularity as a less invasive option for HS.
Carbon Dioxide Laser: CO2 laser ablation can effectively remove HS lesions and sinus tracts with minimal damage to surrounding tissue. It can also promote quicker healing and less scarring compared to traditional surgical methods.
Nd
Laser: This laser targets hair follicles, which are often involved in HS pathology. By reducing hair growth, Nd
laser treatment can decrease the occurrence of new lesions.

Lifestyle and Complementary Therapies
In addition to medical and surgical treatments, lifestyle modifications and complementary therapies play a crucial role in managing HS. These approaches can help reduce symptoms, prevent flare-ups, and improve overall quality of life.
Weight Management
Obesity is a known risk factor for HS, and weight reduction can significantly improve symptoms. Weight management strategies include dietary changes, increased physical activity, and, in some cases, bariatric surgery for those with severe obesity.
Smoking Cessation
Smoking has been linked to the severity of HS, and quitting smoking can lead to a significant improvement in symptoms. Smoking cessation programs, counseling, and medications can assist patients in stopping smoking.
Stress Management
Stress is known to exacerbate HS, so managing stress through techniques like mindfulness, meditation, and cognitive-behavioral therapy (CBT) can be beneficial. Patients may also benefit from support groups and counseling to cope with the psychological burden of the disease.
Dietary Modifications
Some studies suggest that certain dietary changes can help manage HS symptoms. For instance, reducing intake of dairy products and foods with a high glycemic index may help some patients. Additionally, incorporating anti-inflammatory foods, such as those rich in omega-3 fatty acids, can be beneficial.
Complementary Therapies
Complementary therapies, including acupuncture, yoga, and herbal supplements, can provide additional symptom relief for some patients. While the evidence supporting these therapies is limited, they may offer benefits in conjunction with conventional treatments.
Emerging Treatments and Research
Research into new treatments for HS is ongoing, with several promising therapies currently under investigation.
Janus Kinase (JAK) Inhibitors
JAK inhibitors are a new class of drugs that target specific pathways involved in the immune response. Preliminary studies have shown that JAK inhibitors, such as tofacitinib and baricitinib, may be effective in reducing HS symptoms.
IL-17 Inhibitors
IL-17 is a cytokine involved in inflammatory processes. IL-17 inhibitors, such as secukinumab, are being studied for their potential to treat HS by reducing inflammation.
Stem Cell Therapy
Stem cell therapy is an innovative approach that involves using stem cells to promote tissue repair and reduce inflammation. While still in the experimental stages, early results indicate that stem cell therapy could offer a new treatment avenue for HS.
Conclusion
Hidradenitis suppurativa is a challenging and often debilitating condition that requires a multifaceted treatment approach. While there is no cure, a combination of medical, surgical, and lifestyle interventions can effectively manage symptoms and improve quality of life for patients. Advances in biologic therapies and ongoing research into new treatments offer hope for better management and outcomes in the future. Patients with HS should work closely with their healthcare providers to develop a personalized treatment plan that addresses their specific needs and optimizes their overall health.
