Both conditions can profoundly affect quality of life. HS primarily manifests as painful, recurring lumps beneath the skin, while lupus is an autoimmune condition capable of attacking nearly any organ system. Emerging research suggests these disorders may not be entirely separate; instead, they could share immune system dysfunction, genetic predispositions, and overlapping risk factors.
For individuals managing HS, lupus, or both, understanding these connections isn’t just academic—it can shape treatment choices, lifestyle modifications, and long-term health outcomes. In this comprehensive guide, we’ll explore the relationship between hidradenitis suppurativa and lupus, review current research, highlight shared features, and discuss practical strategies for living well with one or both conditions.
What is Hidradenitis Suppurativa?
Hidradenitis suppurativa (HS) is a chronic, progressive skin condition marked by painful, inflamed lumps that often recur in areas where skin rubs against skin. These include the armpits, groin, buttocks, and under the breasts. Over time, HS lesions can rupture, release pus with an unpleasant odor, and form sinus tracts (tunnels) beneath the skin, leading to scarring and thickened tissue.
Key Features of HS:
- Painful nodules resembling deep cystic pimples
- Recurrent abscesses that may ooze foul-smelling fluid
- Sinus tracts or tunnels under the skin
- Permanent scarring in affected regions
- Gradual worsening if left untreated
HS is more common than many realize. Studies suggest up to 4% of the U.S. population may have HS, though many cases remain undiagnosed due to the sensitive body areas involved and stigma surrounding its symptoms.
Living with HS: The Human Impact
Beyond the physical discomfort, HS carries a heavy emotional burden. Patients often describe feelings of shame, embarrassment, or isolation. For example, someone with recurrent HS lesions in the underarms may avoid lifting their arms in public, while others might withdraw socially due to drainage and odor.
This highlights the importance of early diagnosis and holistic treatment—not just for physical healing but for preserving mental well-being and quality of life.
What is Lupus?
Systemic lupus erythematosus (SLE), commonly known as lupus, is an autoimmune disease in which the immune system mistakenly attacks healthy tissues. Instead of defending the body, the immune system causes widespread inflammation that can affect nearly every organ, from the skin and joints to the kidneys, heart, lungs, and brain.
Common Symptoms of Lupus:
- Butterfly-shaped rash across the cheeks and nose
- Joint pain and swelling
- Severe fatigue that doesn’t improve with rest
- Recurrent fevers
- Hair thinning or loss
- Sensitivity to sunlight (photosensitivity)
- Kidney issues such as swelling or changes in urination
- Neurological symptoms (e.g., confusion, headaches, seizures) in severe cases
According to estimates, lupus affects about 73 out of every 100,000 people in the U.S., with the vast majority being women of childbearing age.
The Daily Challenges of Lupus
Lupus is known for its unpredictability. Patients may experience periods of relative calm (remission) followed by sudden flare-ups where symptoms worsen dramatically. This unpredictability can make it difficult to plan daily life. For example, a lupus patient might feel fine one week but be bedridden the next due to overwhelming fatigue or joint pain.
Because lupus can mimic other illnesses, diagnosis often takes years, during which patients may feel invalidated or misunderstood. This reality underscores the need for awareness, research, and patient-centered care.
HS vs. Lupus: How Are They Similar and Different?
At first glance, HS and lupus appear unrelated—one is a skin disease, and the other is a systemic autoimmune condition. However, researchers have uncovered striking similarities in how these conditions affect the body.
Shared Characteristics
- Immune Dysregulation: Both involve abnormal immune system activity. Lupus is formally recognized as an autoimmune disease, while HS shows autoimmune-like features, including the presence of certain autoantibodies.
- Chronic Inflammation: Both conditions create long-lasting inflammatory states that affect quality of life and increase the risk of long-term complications.
- Progressive Nature: Without treatment, HS can cause severe scarring, and lupus can lead to permanent organ damage.
- Impact on Quality of Life: Both conditions cause physical pain, emotional stress, and social difficulties due to visible symptoms and unpredictable flares.
Key Differences
- Primary Target: HS mainly affects the skin, whereas lupus can target multiple organ systems.
- Classification: Lupus is definitively autoimmune; HS is considered inflammatory with autoimmune-like traits.
- Symptom Patterns: HS lesions are localized, while lupus symptoms often appear throughout the body.
- Diagnostic Markers: Lupus diagnosis relies on blood tests for autoantibodies, while HS is diagnosed clinically based on lesion patterns and history.
What Does Research Say About the HS-Lupus Connection?
Evidence of a Link
Research in recent years has suggested that HS and lupus may be connected through shared pathways of immune dysfunction.
- A 2022 study analyzing health records of over 600 HS patients found that autoimmune diseases—including lupus—were more common among those with HS compared to the general population.
- Another 2020 study reported that people with HS are nearly twice as likely to develop lupus as those without HS.
These findings raise important questions: Is HS itself autoimmune, or does it simply make people more prone to developing autoimmune conditions like lupus?
Treatment Complications
Some medications used to treat HS, such as TNF inhibitors, have been linked to drug-induced lupus in rare cases. This makes it difficult to determine whether lupus arises naturally alongside HS or as a side effect of treatment.
Case Study Insights
Case reports, such as one from 2018, describe patients diagnosed with both HS and lupus. These clinical examples add weight to the idea that these conditions can coexist in the same patient, possibly due to shared genetic or immune-related factors.
Expert Perspectives: How Do Specialists View the Connection?
Most researchers agree that HS and lupus share immune system abnormalities, but the exact nature of their relationship remains unclear.
Some experts suggest HS lies on a spectrum of inflammatory diseases that overlap with autoimmunity. Others argue that HS patients may simply be more vulnerable to autoimmune diseases in general.
What’s certain is that both conditions are under-researched, and more studies are urgently needed to clarify:
- Which genes or environmental triggers increase risk
- Whether treating one condition early could prevent the other
- How best to treat patients who suffer from both
Living with HS and Lupus: Practical Management Strategies
For patients dealing with both HS and lupus, treatment can be complicated. Because therapies for one condition may affect the other, an integrated care approach involving dermatologists, rheumatologists, and primary care physicians is essential.
Medication Considerations
- Some biologics (targeted immune therapies) may benefit both HS and lupus, but careful monitoring is necessary.
- Physicians must balance immunosuppressants with the risk of infections and medication side effects.
- Regular blood work and imaging tests help track disease progression.
Lifestyle Modifications
- Stress Management: Stress is a known trigger for both HS and lupus flares. Practices like meditation, yoga, and therapy can help.
- Smoking Cessation: Smoking is a major risk factor for HS and worsens lupus outcomes. Quitting can significantly improve prognosis.
- Healthy Weight: Weight management helps reduce friction in HS-prone areas and eases joint pain in lupus.
- Sun Protection: While crucial for lupus patients due to photosensitivity, sun safety also benefits HS by protecting overall skin health.
Skin and Wound Care
Patients with both conditions need tailored skin care routines:
- Gentle, fragrance-free cleansers
- Careful wound care for draining HS lesions
- Coordination between dermatology and rheumatology teams to prevent skin irritation from overlapping treatments
Treatment Options
For HS
- Topical therapies: Antibiotic creams or cleansers
- Oral medications: Antibiotics, retinoids, hormonal therapies
- Biologics: TNF inhibitors, IL-17A inhibitors
- Surgery: Drainage or removal of damaged tissue
- Lifestyle support: Smoking cessation, weight management
For Lupus
- NSAIDs: To ease joint pain
- Antimalarials (e.g., hydroxychloroquine): To reduce skin and joint flares
- Corticosteroids: For severe inflammation
- Immunosuppressants: To control overactive immune responses
- Biologics: Newer drugs designed to target specific immune pathways
Coordinated Care is Key
For patients with both conditions, doctors must:
- Monitor drug interactions carefully
- Adjust medications according to disease activity
- Provide holistic support that addresses mental, emotional, and physical health
When to Seek Medical Help
Patients with HS should seek medical attention if they develop:
- New rashes (especially butterfly rash)
- Joint pain or unexplained swelling
- Persistent fever or fatigue
- Changes in urination (possible kidney issues)
Lupus patients should alert their doctor if they notice:
- New painful lumps under the skin (HS-like lesions)
- Signs of skin infection or poor wound healing
- Unexplained flare-ups in friction-prone areas
Early intervention can significantly improve quality of life and prevent irreversible complications.
Future Directions: Where is Research Headed?
Scientists are actively investigating the HS-lupus connection through:
- Genetic studies to identify shared risk factors
- Population studies to track prevalence
- Drug trials to test therapies that may work for both conditions
- Mechanistic research into shared inflammatory pathways
The ultimate goal is personalized medicine—tailoring treatments to a patient’s genetic and immune profile to maximize effectiveness while minimizing risks.
Final Thoughts: Hope on the Horizon
The growing recognition of connections between hidradenitis suppurativa and lupus marks an important step in understanding complex chronic illnesses. For patients, this knowledge offers not only validation but also hope for better treatments.
While both conditions can be life-altering, patients can take proactive steps:
- Stay informed about emerging research
- Communicate openly with healthcare providers
- Practice lifestyle habits that support immune health
- Seek emotional and social support to cope with the burden of chronic illness
The medical community is steadily uncovering new insights into these conditions, moving toward integrated treatment approaches and targeted therapies that may one day transform outcomes for millions of people.
Until then, patients living with HS, lupus, or both should remember: you are not alone, your symptoms are real, and effective support and treatment options are available. With knowledge, advocacy, and medical progress, the future holds promise for a better quality of life.
