Hidradenitis Suppurativa: Symptoms, Causes, Treatment

What are the symptoms of hidradenitis suppurativa?

Hidradenitis suppurativa (HS) is a chronic skin condition characterized by painful, inflamed lesions in areas of the body where skin rubs together, such as the armpits, groin, buttocks, and under the breasts. The symptoms can vary in severity and may include:

1. Painful Lumps: The condition often starts with small, painful lumps under the skin that may be red and inflamed. These lumps can persist for weeks or months.
2. Abscesses: These lumps may develop into painful abscesses that fill with pus. Abscesses can rupture, leading to drainage of foul-smelling fluid.
3. Tunnels: Over time, tunnels (sinus tracts) may form under the skin, connecting multiple abscesses. These tracts can be painful and may discharge fluid.
4. Blackheads: Small blackheads, often appearing in pairs, may develop in the affected areas.
5. Scarring: The repeated cycles of inflammation, abscess formation, and healing can lead to significant scarring and thickening of the skin in the affected areas.
6. Itching and Discomfort: The affected areas may be itchy and uncomfortable, and the skin can become swollen and tender.
7. Restricted Movement: Severe cases of HS can restrict movement due to pain and swelling in affected areas.
8. Systemic Symptoms: In some cases, HS can be associated with fatigue, fever, and other systemic symptoms, particularly if there is a secondary infection.

HS can vary greatly in severity, and while some people may have mild symptoms, others may experience significant and recurrent problems that impact their quality of life. Early diagnosis and treatment are important to manage the condition and reduce the risk of complications. If you suspect you have hidradenitis suppurativa, it’s important to consult a healthcare provider for appropriate evaluation and management.

What are the causes of hidradenitis suppurativa?

The exact cause of hidradenitis suppurativa (HS) is not fully understood, but several factors are believed to contribute to its development. These include:

1. Genetic Predisposition: HS tends to run in families, suggesting a genetic component. Specific genetic mutations or variations may increase susceptibility to the condition.
2. Immune System Dysfunction: HS is thought to involve an abnormal response of the immune system, leading to chronic inflammation. The immune system may overreact to blockages in hair follicles and sweat glands, causing inflammation and abscess formation.
3. Follicular Occlusion: Blockage of hair follicles and sweat glands is a key feature of HS. The exact mechanism is unclear, but it may involve abnormal keratinization (the process by which skin cells form and shed), leading to clogging of the follicles.
4. Hormonal Factors: HS often starts after puberty and can be influenced by hormonal changes. Fluctuations in hormones, particularly androgens, may play a role in the development and exacerbation of the condition.
5. Environmental and Lifestyle Factors: Certain lifestyle factors can exacerbate HS, including smoking and obesity. These factors may worsen inflammation and contribute to disease severity.
6. Bacterial Involvement: While HS is not primarily caused by infection, secondary bacterial infections can occur in the affected areas, worsening inflammation and symptoms.
7. Mechanical Friction and Sweat: Areas of the body where skin rubs together (such as the armpits, groin, and under the breasts) are commonly affected. Friction and sweating in these areas may contribute to follicular occlusion and inflammation.
8. Metabolic Syndrome: There is an association between HS and metabolic syndrome, which includes conditions like obesity, insulin resistance, and dyslipidemia. This suggests a potential link between metabolic health and HS.

It is important to note that HS is a multifactorial disease, and the interplay of genetic, environmental, and immunological factors likely contributes to its development and progression. Managing HS typically involves addressing these factors through medical treatment, lifestyle changes, and supportive care. If you suspect you have HS, consulting with a dermatologist or healthcare provider is essential for proper diagnosis and management.

How is the diagnosis of hidradenitis suppurativa made?

The diagnosis of hidradenitis suppurativa (HS) is typically made based on a combination of clinical examination, medical history, and sometimes additional tests. Here’s how it is generally diagnosed:

1. Medical History: Your doctor will ask about your symptoms, including the location, duration, and severity of any lumps, abscesses, or tunnels under the skin. They will also inquire about any family history of HS or related conditions.
2. Physical Examination: A thorough physical examination is crucial. The doctor will inspect the affected skin areas, looking for characteristic signs such as inflamed nodules, abscesses, sinus tracts (tunnels under the skin), scarring, and blackheads (comedones).
3. Diagnostic Criteria: Diagnosis is often based on specific criteria established by medical organizations such as the International Hidradenitis Suppurativa Foundation (HIDRAdisk criteria) or Hurley staging system, which categorizes the severity of the disease based on the extent of involvement and scarring.
4. Exclusion of Other Conditions: Sometimes, other conditions with similar symptoms, such as boils, folliculitis, or acne, need to be ruled out through examination and possibly additional tests.
5. Biopsy: In some cases, a skin biopsy may be performed to confirm the diagnosis. A small sample of affected skin tissue is removed and examined under a microscope to look for characteristic changes associated with HS.
6. Imaging Studies: In severe or complicated cases, imaging studies such as ultrasound or MRI may be used to evaluate the extent of involvement and identify tunnels (sinus tracts) beneath the skin.
7. Blood Tests: Blood tests may be ordered to check for signs of inflammation and to rule out other conditions that can mimic HS or contribute to its development.

Because HS can vary widely in severity and presentation, diagnosis may require a comprehensive evaluation by a dermatologist or healthcare provider experienced in managing skin disorders. Early diagnosis is important for initiating appropriate treatment to manage symptoms, prevent complications, and improve quality of life. If you suspect you have HS or have persistent skin issues in sensitive areas, it’s crucial to seek medical attention for proper evaluation and management.

What is the treatment for hidradenitis suppurativa?

Hidradenitis suppurativa (HS) is a chronic skin condition characterized by recurring, painful abscesses and nodules in the apocrine-gland-bearing areas of the body, such as the armpits, groin, and buttocks. The treatment of HS typically involves a combination of self-care measures, lifestyle changes, and medical interventions. Here are some common treatments for HS:

Self-care measures:

1. Keep the affected areas clean: Gently wash the affected areas with soap and warm water, pat dry thoroughly.
2. Avoid tight clothing: Wearing loose, breathable clothing can help reduce friction and irritation.
3. Avoid heavy sweating: Minimize physical activity, wear light, loose clothing, and use antiperspirants or deodorants to reduce sweating.
4. Apply warm compresses: Applying a warm compress to the affected area may help reduce pain and swelling.

Lifestyle changes:

1. Maintain a healthy weight: Excess weight can contribute to HS symptoms.
2. Reduce stress: Stress can exacerbate HS symptoms; engage in stress-reducing activities like meditation, yoga, or deep breathing exercises.
3. Improve hygiene: Regularly showering and using antibacterial soap can help prevent bacterial infections.

Medical interventions:

1. Antibiotics: Oral antibiotics may be prescribed to treat bacterial infections that cause HS symptoms.
2. Anti-inflammatory medications: Medications like corticosteroids or anti-inflammatory creams may help reduce inflammation and swelling.
3. Retinoids: Topical retinoids, such as adapalene or tretinoin, can help reduce inflammation and prevent new lesions from forming.
4. Hormonal therapies: In some cases, hormonal therapies like birth control pills or anti-androgen medications may be prescribed to reduce hormonal imbalances that contribute to HS.
5. Surgical drainage: In severe cases, surgical drainage of abscesses or nodules may be necessary to relieve pain and reduce scarring.
6. Laser therapy: Laser therapy may be used to reduce inflammation and scarring.
7. Moisturizers: Topical moisturizers can help soothe dry skin and reduce itching.

Other treatments:

1. Biologics: Biologic medications like infliximab or adalimumab may be prescribed to reduce inflammation and promote healing.
2. Phototherapy: Ultraviolet B (UVB) light therapy may help reduce inflammation and improve symptoms.
3. Surgery: Surgical removal of affected tissue or excision of abscesses may be necessary in severe cases.

It’s essential to work with a healthcare provider to develop a personalized treatment plan that addresses individual symptoms and needs. With proper treatment and self-care, many people with hidradenitis suppurativa can manage their symptoms and improve their quality of life.
