Medical disclaimer: This website is for general educational information only and does not replace medical advice, diagnosis, or treatment.

What this update covers - Query: ("hidradenitis suppurativa" OR "acne inversa") - Entrez date field: edat - Window: 2026-05-12 to 2026-05-20 - New PubMed items included below: 15 Top highlights In short: this week’s abstracts focus on patient-relevant outcomes (pain/quality of life), real-world care questions, and signals around comorbidities. - Comorbidities and systemic aspects (e.g., metabolic, musculoskeletal, IBD) show up repeatedly. (PMIDs 42147604, 42117990, 42153035, 42156635) - Some abstracts relate to surgical/structural questions (e.g., fistulas/complications) around HS care. (PMIDs 42131295, 42137224, 42117990) - Pain and disease control are increasingly treated as explicit study outcomes and targets. (PMIDs 42131295, 42137224) - Several abstracts focus on quality of life, stigma, and patient-relevant outcome measures (e.g., DLQI/HiSQOL). (PMIDs 42131295, 42137224) What this may mean for patients (carefully, no advice) If you live with HS, research updates can help you make sense of what’s being studied — for example which outcomes (pain, quality of life) researchers measure, or which comorbidities are increasingly part of the conversation. If you are new to the condition, our overview of what acne inversa is (/en/blog/what-is-acne-inversa/) may give helpful context for these terms. But even when a study sounds promising, it usually does not tell you what is right for you personally. Consider using new findings as questions for your next appointment (/en/blog/15-questions-to-ask-your-dermatologist/) (e.g., “What are realistic goals for me?” or “Which related conditions should we keep an eye on?”), not as instructions. What we don’t know / limitations - This update includes only PubMed items with an abstract (without an abstract, safe summarization is limited). - Studies vary widely (design, populations, outcome measures). - This update provides no treatment advice and cannot assess individual risk. Publication overview - Publications (with abstracts) in this window: 15 - Common topics: comorbidities, quality of life, biologics, surgery, pain - Compared with last week: not available yet (this is the first update in this series). - No guideline/NEJM/Lancet-style high-impact matches with abstracts in this window. - Featured publication: Clinical, cosmetic and investigational dermatology — Focus on quality of life/burden and how studies measure it. (PMID 42131295) Important: decisions belong in clinician conversations If something here worries or interests you, use it as a conversation starter for your next appointment. Recognizing patterns early can also matter — see our guide on recognizing hidradenitis suppurativa before it progresses (/en/blog/recognizing-hidradenitis-suppurativa-early/). Decisions should always be made with qualified healthcare professionals. Sources & original papers Each point below maps to an original source (PubMed link, plus DOI/PMCID when available). FAQ What does this HS research update cover? It summarizes 15 PubMed publications on hidradenitis suppurativa (acne inversa) indexed between May 12 and May 20, 2026, with a focus on quality of life, comorbidities, surgery, and pain. Is this medical advice? No. This is an editorial overview for patient education. It is not medically reviewed and does not replace advice, diagnosis, or treatment from a qualified clinician. How should I use this update? Use it as a conversation starter for your next dermatology appointment — for example to ask about realistic treatment goals or which comorbidities to monitor. Why are quality-of-life measures important in HS research? Because HS affects pain, mental health, and daily function, researchers increasingly use patient-reported outcome measures (such as DLQI or HiSQOL) to capture the real burden beyond visible lesions.
