Evaluating patients' unmet needs in hidradenitis suppurativa: Results from the Global Survey Of Impact and Healthcare Needs (VOICE) Project

The Influence of Pain on Reduced Quality of Life in Patients with Hidradenitis Suppurativa: A Single-Center Retrospective Study

BACKGROUND

Pain and itch are impactful and burdensome symptoms of hidradenitis suppurativa (HS). Elucidating factors associated with pain and itch severity may identify groups disproportionally affected by HS-related pain and itch and further our understanding of how pain and itch impact quality of life (QoL) in patients with HS.

OBJECTIVE

The objective of the study was to determine factors associated with pain severity, itch severity, and reduced QoL in patients with HS.

METHODS

This is a retrospective cross-sectional study of 257 adults with HS who received care in an HS Specialty Clinic from January 2019 to August 2021. Multivariable mixed-effects linear regression was used to determine the relationships between clinical and demographic patient factors and the outcomes of pain severity, itch severity, and skin-specific QoL.

RESULTS

Factors associated with reduced QoL were Hurley stage II (β = 19.66, 95% CI: 1.40-37.93) and III (β = 21.98, 95% CI: 1.57-42.39) disease as well as severity of pain (β = 13.74, 95% CI: 11.93-15.55), itch (β = 4.57, 95% CI: 2.59-6.55), anxiety (β = 2.55 95% CI: 1.29-3.81), and depression (β = 1.43, 95% CI: 0.30-2.56). Increasing HS pain severity was associated with Hurley stage III disease (β = 2.04, 95% Cl: 0.99-3.09), black race (β = 1.23, 95% Cl: 0.40, 2.06), depression severity (β = 0.08, 95% Cl: 0.02, 0.14), and anxiety severity (β = 0.10 95% Cl: 0.04, 0.17). Factors associated with HS itch severity were Hurley stage III disease (β = 2.23, 95% Cl: 1.19, 3.27), black race (β = 0.92, 95% Cl: 0.07, 1.78), depression severity (β = 0.09, 95% Cl: 0.04, 0.14), and anxiety severity (β = 0.07, 95% Cl: 0.01, 0.13).

CONCLUSION

Pain is one of the largest contributors to QoL in patients with HS; on a 0-10 numeric rating scale, a 2-point increase in HS pain had a similar independent effect on QoL as having Hurley stage III disease compared to Hurley stage I.

Understanding Hurley Stage III Hidradenitis Suppurativa Patients' Experiences With Pain: A Cross-Sectional Analysis

BACKGROUND

More than 90% of patients with hidradenitis suppurativa (HS) report that pain interferes with their quality of life (QoL) and pain may have a larger impact on QoL than disease severity alone.

OBJECTIVES

The purpose of this study was to understand the impact of pain on the daily lives of patients with Hurley stage III HS.

METHODS

This was a single-center, prospective cross-sectional study that was conducted at Beacon Dermatology in Calgary, AB. Patients ≥ 18 years old with Hurley stage III HS in at least one area of the body were prospectively invited to participate in this study. The study consisted of survey questions on patients' demographic information, past medical histories, HS-related pain histories, and previous therapies for pain management. Additionally, patients completed a series of standardized rating scales on their pain and overall QoL.

RESULTS

Of the 10 patients that participated in the study, 90% (9/10) expressed a desire for more counselling on pain management options. Many patients (8/10, 80%) reported routine use of over-the-counter pain medications and 70% (7/10) used complementary and alternative medicines (CAMs) to manage their pain. Patients' efficacy ratings of HS treatments in controlling their pain revealed that topical treatments provided minimal or no relief, while surgical interventions had the highest efficacy for reducing pain. Patients' average worst pain over the preceding 24 hrs was 6.3 +/- 2.5 (2-9) on the Numerical Rating Scale for pain and the mean Dermatology Life Quality Index score was 19.5 +/- 8.2 (5-29).

CONCLUSIONS

Patients with Hurley stage III HS report high levels of daily pain and QoL impairment and many individuals use over-the-counter treatments and CAMs to manage their pain. Physicians involved in the care of HS patients should consider implementing routine counselling on pain management into their clinical practices, especially for patients with severe HS.

Patient-reported influences on COVID-19 vaccine acceptance and hesitancy in people with hidradenitis suppurativa

COVID-19 continues to pose a risk to patients with hidradenitis suppurativa (HS) due to the high prevalence of comorbidities associated with severe COVID-19 disease. We aimed to characterize perspectives on COVID-19 vaccination among patients with HS. International respondents from 20 online HS support groups were recruited to complete a voluntary, anonymous, online cross-sectional survey from 25 October to 21 November 2021 to obtain perspectives from people with HS who may and may not access healthcare. We report higher rates of COVID-19 vaccine hesitancy among patients with HS who expressed dissatisfaction with their dermatological care.

Inborn Errors of Immunity in Hidradenitis Suppurativa Pathogenesis and Disease Burden

Hidradenitis suppurativa (HS), also known as Verneuil's disease and acne inversa, is a prevalent, debilitating, and understudied inflammatory skin disease. It is marked by repeated bouts of pathological inflammation causing pain, hyperplasia, aberrant healing, and fibrosis. HS is difficult to manage and has many unmet medical needs. There is clinical and pharmacological evidence for extensive etiological heterogeneity with HS, suggesting that this clinical diagnosis is capturing a spectrum of disease entities. Human genetic studies provide robust insight into disease pathogenesis. They also can be used to resolve etiological heterogeneity and to identify drug targets. However, HS has not been extensively investigated with well-powered genetic studies. Here, we review what is known about its genetic architecture. We identify overlap in molecular, cellular, and clinical features between HS and inborn errors of immunity (IEI). This evidence indicates that HS may be an underrecognized component of IEI and suggests that undiagnosed IEI are present in HS cohorts. Inborn errors of immunity represent a salient opportunity for rapidly resolving the immunological landscape of HS pathogenesis, for prioritizing drug repurposing studies, and for improving the clinical management of HS.

Clinical and Ultrasonographic Characterization of Hidradenitis Suppurativa in Female Patients: Impact of Early Recognition of the Disease

Hidradenitis suppurativa (HS) is considered a post-pubertal disease; however, earlier onset is not infrequent. The burden of HS on the female population is very relevant, and early identification might reduce the quality of life impairment and improve the therapeutic approach. In this study, we investigated clinical biomarkers of HS that could impact the management of patients affected by HS. Female patients affected by stable HS were prospectively included in this study. Anamnestic data, clinical and ultrasonographic features were collected and analyzed. Overall, 53 patients were included in this study. The median age of onset was 19 (IQR: 14-25). Early onset was reported by 22/53 patients (median age of onset: 14; IQR: 11-16). Four patients had pre-menstruation occurrence. Early-onset patients had an earlier first-menstrual-cycle age and more frequent genital localization of HS, and were more often treated with biologics. Patients with early-onset-HS and genital localization had more severe disease with a higher number of areas affected, Hurley, and IHS4 scores. Genital involvement might be prevalent in patients with early-onset HS, leading to a worse impact on the global severity of the disease and tailored treatment protocols, including multidisciplinary approaches, in order to improve the early recognition of hidden lesions.

A centre-based ambulatory care concept for hidradenitis suppurativa improves disease activity, disease burden and patient satisfaction: results from the randomized controlled EsmAiL trial

BACKGROUND

Hidradenitis suppurativa (HS) is an inflammatory disease of the inverse skin regions that occurs in young women, in particular, and affects approximately 1% of the population. Outpatient care is often inadequate and usually cannot prevent progression.

OBJECTIVES

To evaluate in the EsmAiL ('Evaluation eines strukturierten und leitlinienbasierten multmodalen Versorgungskonzepts für Menschen mit Akne inversa') trial whether an innovative care concept can decrease disease activity and burden, and improve patient satisfaction.

METHODS

EsmAiL was conducted as a two-arm, multicentre, prospective, randomized controlled trial that included 553 adults with HS. Inclusion criteria were a minimum of three inflammatory lesions and at least a moderate impact of the disease on quality of life. The control group (CG) remained under standard care, while patients in the intervention group (IG) were treated according to a trial-specific, multimodal concept. The primary endpoint was the absolute change in International Hidradenitis Suppurativa Severity Score System (IHS4).

RESULTS

In total, 274 patients were randomized to the IG and 279 to the CG. Altogether, 377 attended the final assessment after 12 months of intervention. Participants in the IG (n = 203) achieved a mean improvement in IHS4 of 9.3 points, while the average decrease in IHS4 in patients in the CG (n = 174) was 5.7 points (P = 0.003). Patients treated under the new care concept also reported a statistically significantly higher decrease in pain, Dermatology Life Quality Index and Hospital Anxiety and Depression Scale scores compared with those in the CG (P < 0.001). Patient satisfaction was also statistically significantly higher in the IG compared with the CG (P < 0.001).

CONCLUSIONS

The establishment of standardized treatment algorithms in so-called 'acne inversa centres' in the ambulatory setting has a substantial, positive impact on the course of HS and significantly improves patient satisfaction.

Understanding the real-world patient journey and unmet needs of people with hidradenitis suppurativa through social media research

People with hidradenitis suppurativa (HS) have a high burden of unmet needs and a better understanding of their lived experience is needed. Social media research is a novel approach that can improve such understanding by collecting and analysing publicly available information related to patient experiences. This study found that people with HS are unhappy with the management of their disease and highlights the need for greater awareness and research, as well as treatment effectiveness and options.

Obstacles to Early Diagnosis and Treatment of Hidradenitis Suppurativa: Current Perspectives on Improving Clinical Management

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that can progress to significant tunnels and scars that affect quality of life, especially if diagnosis and treatment are delayed. Average delay after initial presentation of HS symptoms can range from 3 to 10 years in adults and 1 to 2 years in children. Factors associated with diagnostic delay include female gender, non-white race, and greater disease severity at diagnosis. Contributing factors include misdiagnoses, difficulty accessing a dermatologist, hesitation in seeking care due to the stigmatizing nature of the disease, and lack of awareness among providers and patients. While efforts to increase awareness include academic talks at conferences and by foundations geared toward HS, social media offers the opportunity to reach young audiences. Many patients report dissatisfaction with their HS treatments. Better understanding of HS pathophysiology and implementation of clinically focused phenotypes and endotypes can lead to development of more targeted and efficacious therapies. FDA approval of medications for HS beyond adalimumab will increase access to a wider selection of therapies, and implementation of therapeutic drug monitoring may maximize the use of biologics for HS.

Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic disease characterized by recurrent painful abscesses and chronic sinus tracts in intertriginous areas. In the United States, HS disproportionally affects adults of African-American heritage. Depending on the severity of disease, the consequences of HS can be far-reaching, significantly affecting mental health and quality of life. In recent years, concerted research efforts have been made to better understand the pathophysiology of the disease as well as identify emerging new treatment targets. Herein, we discuss the clinical presentation, diagnostic criteria, and treatment approach of HS with a focus on skin of color.

Effect of Biologics on the Need for Procedural Interventions, Systemic Medications, and Healthcare Utilization in Patients with Hidradenitis Suppurativa: Real-World Data from the UNITE Registry

INTRODUCTION

Management of hidradenitis suppurativa (HS) often requires a combined medical/procedural approach. Biologics are frequently reserved for severe cases after irreversible tissue damage has occurred. We evaluated the association between consistent biologic use and the need for procedural interventions, systemic medications, and healthcare utilization.

METHODS

UNITE, a 4-year, global, prospective, observational, HS disease registry, documented the natural history, diagnostic/treatment patterns, and clinical outcomes of HS. Patients aged 12 years or more, with active HS were enrolled between October 2013 and December 2015 and evaluated every 6 months for 48 months at 73 sites across 12 countries (data cutoff December 2019). Proportions of patients requiring different HS procedures, systemic medications, and healthcare utilization were assessed during the 6-month periods before, during, and after biologic initiation for 12 weeks or more (i.e., consistent use).

RESULTS

There were 63 instances of initiation of consistent biologic use (adalimumab [81%], infliximab [16%], and ustekinumab [3%]) in 57 patients. Patients' mean age was 40 years, 58% were female, and 53%/47% had Hurley stage II/III disease, respectively. Fewer patients required surgical/procedural interventions and systemic medications for the 6-month period during/6-month period after biologic initiation versus the 6-month period before biologic initiation, including intralesional corticosteroid injections (22%/14% vs 24%), incision and drainage (I&D) by physician (10%/10% vs 17%), I&D by patient (10%/10% vs 14%), surgical excision (8%/10% vs 11%), deroofing (5%/2% vs 5%), systemic antibiotics (43%/41% vs 54%), and systemic immunosuppressants (10%/6% vs 13%). Fewer patients required hospital admission for HS (17%/13% vs 21%) or emergency department visits for HS (8%/8% vs 16%) during the 6-month periods in which consistent biologics use started and continued versus the 6-month period before consistent biologic use.

CONCLUSION

Following initiation of consistent biologic use (12 weeks or more), fewer patients required acute procedural interventions, systemic medications, and healthcare utilization, supporting the importance of early biologic initiation.

Clinical and Molecular Characterization of Hidradenitis Suppurativa: A Practical Framework for Novel Therapeutic Targets

BACKGROUND

The pathophysiological picture underlying hidradenitis suppurativa (HS) and its syndromic forms is still patchy, thus presenting a great challenge for dermatologists and researchers since just by better understanding the pathogenesis of disease we could identify novel therapeutic targets.

METHODS

We propose a practical framework to improve subcategorization of HS patients and support the genotype-phenotype correlation, useful for endotype-directed therapies development.

RESULTS

This framework includes (i) clinical work-up that involves the collection of demographic, lifestyle, and clinical data as well as the collection of different biological samples; (ii) genetic-molecular work-up, based on multi-omics analysis in combination with bioinformatics pipelines to unravel the complex etiology of HS and its syndromic forms; (iii) functional studies, - represented by skin fibroblast cell cultures, reconstructed epidermal models (both 2D and 3D) and organoids -, of candidate biomarkers and genetic findings necessary to validate novel potential molecular mechanisms possibly involved and druggable in HS; (iv) genotype-phenotype correlation and clinical translation in tailored targeted therapies.

CONCLUSION

Omic findings should be merged and integrated with clinical data; moreover, the skin-omic profiles from each HS patient should be matched and integrated with the ones already reported in public repositories, supporting the efforts of the researchers and clinicians to discover novel biomarkers and molecular pathways with the ultimate goal of providing faster development of novel patient-tailored therapeutic approaches.

Patient Perspectives of Health System Barriers to Accessing Care for Hidradenitis Suppurativa: A Qualitative Study

Importance

Patient-perceived barriers to hidradenitis suppurativa (HS) care are poorly understood. Understanding health care barriers is a critical first step toward improving care for this population.

Objective

To characterize the health care experiences of people living with HS, including perceived barriers and facilitators to health care access, and to elucidate potential associations among these barriers and facilitators, health care access, and disease activity.

Design, Setting, and Participants

In this qualitative study, an inductive thematic analysis was conducted on 45 in-depth, 60- to 90-minute semistructured interviews of 45 people with HS from diverse sociodemographic backgrounds that took place between March and April 2020. Individuals were eligible if they could speak English, were 18 years or older, and were diagnosed with HS. A diagnosis of HS was confirmed through physician diagnosis or through self-reported, affirmative response to the validated screening question, "Do you experience boils in your armpits or groin that recur at least every six months?"

Main Outcomes and Measures

Interviews were audio recorded and transcribed verbatim. A modified grounded theory approach was used to develop the codebook, which investigators used for inductive thematic analysis.

Results

Among the 45 participants included, the median (IQR) age was 37 (16) years, 33 (73%) were female, and 22 (49%) were White. There were 6 interrelated themes associated with participant-perceived barriers to accessing HS care: (1) bidirectional associations of disease activity and employment, (2) association of employment with health care coverage, (3) association of health care coverage with costs and perceived access to care, (4) association of costs with access to patient-centered care, (5) health care professional attitudes and knowledge influence patient-centered care and perceived access to care and disease activity, and (6) health system characteristics influence patient-centered care and associated costs, perceived access to care, and disease activity.

Conclusions and Relevance

This qualitative study highlights themes that generate a conceptual model for understanding barriers that may act synergistically to limit health care access and influence disease activity. The disease activity of HS may be reduced when cycle elements are optimized. This study also highlights areas for future investigations and potential systems-level changes to improve access to patient-centered HS care.

Secukinumab in moderate-to-severe hidradenitis suppurativa (SUNSHINE and SUNRISE): week 16 and week 52 results of two identical, multicentre, randomised, placebo-controlled, double-blind phase 3 trials

BACKGROUND

Few therapeutic options are available for patients with moderate-to-severe hidradenitis suppurativa. We aimed to assess the efficacy of secukinumab in patients with moderate-to-severe hidradenitis suppurativa in two randomised trials.

METHODS

SUNSHINE and SUNRISE were identical, multicentre, randomised, placebo-controlled, double-blind phase 3 trials done in 219 primary sites in 40 countries. Patients aged 18 years old or older with the capacity to provide written informed consent and with moderate-to-severe hidradenitis suppurativa (defined as a total of ≥5 inflammatory lesions affecting ≥2 distinct anatomical areas) for at least 1 year were eligible for inclusion. Included patients also agreed to daily use of topical over-the-counter antiseptics on the areas affected by hidradenitis suppurativa lesions while on study treatment. Patients were excluded if they had 20 or more fistulae at baseline, had ongoing active conditions requiring treatment with prohibited medication (eg, systemic biological immunomodulating treatment, live vaccines, or other investigational treatments), or met other exclusion criteria. In both trials, patients were randomly assigned (1:1:1) by means of interactive response technology to receive subcutaneous secukinumab 300 mg every 2 weeks, subcutaneous secukinumab 300 mg every 4 weeks, or subcutaneous placebo all via a 2 mL prefilled syringe in a double-dummy method as per treatment assignment. The primary endpoint was the proportion of patients with a hidradenitis suppurativa clinical response, defined as a decrease in abscess and inflammatory nodule count by 50% or more with no increase in the number of abscesses or in the number of draining fistulae compared with baseline, at week 16, assessed in the overall population. Hidradenitis suppurativa clinical response was calculated based on the number of abscesses, inflammatory nodules, draining fistulae, total fistulae, and other lesions in the hidradenitis suppurativa affected areas. Safety was assessed by evaluating the presence of adverse events and serious adverse events according to common terminology criteria for adverse events, which were coded using Medical Dictionary for Regulatory Activities terminology. Both the SUNSHINE, NCT03713619, and SUNRISE, NCT03713632, trials are registered with ClinicalTrials.gov.

FINDINGS

Between Jan 31, 2019, and June 7, 2021, 676 patients were screened for inclusion in the SUNSHINE trial, of whom 541 (80%; 304 [56%] women and 237 [44%] men; mean age 36·1 years [SD 11·7]) were included in the analysis (181 [33%] in the secukinumab every 2 weeks group, 180 [33%] in the secukinumab every 4 weeks group, and 180 [33%] in the placebo group). Between the same recruitment dates, 687 patients were screened for inclusion in the SUNRISE trial, of whom 543 (79%; 306 [56%] women and 237 [44%] men; mean age 36·3 [11·4] years) were included in the analysis (180 [33%] in the secukinumab every 2 weeks group, 180 [33%] in the secukinumab every 4 weeks group, and 183 [34%] in the placebo group). In the SUNSHINE trial, significantly more patients in the secukinumab every 2 weeks group had a hidradenitis suppurativa clinical response (rounded average number of patients with response in 100 imputations, 81·5 [45%] of 181 patients) compared with the placebo group (60·7 [34%] of 180 patients; odds ratio 1·8 [95% CI 1·1-2·7]; p=0·0070). However, there was no significant difference between the number of patients in the secukinumab every 4 weeks group (75·2 [42%] of 180 patients) and the placebo group (1·5 [1·0-2·3]; p=0·042). Compared with the placebo group (57·1 [31%] of 183 patients), significantly more patients in the secukinumab every 2 weeks group (76·2 [42%] of 180 patients; 1·6 [1·1-2·6]; p=0·015) and the secukinumab every 4 weeks group (83·1 [46%] of 180 patients; 1·9 [1·2-3·0]; p=0·0022) had a hidradenitis suppurativa clinical response in the SUNRISE trial. Patient responses were sustained up to the end of the trials at week 52. The most common adverse event by preferred term up to week 16 was headache in both the SUNSHINE (17 [9%] patients in the secukinumab every 2 weeks group, 20 [11%] in the secukinumab every 4 weeks group, and 14 [8%] in the placebo group) and SUNRISE (21 [12%] patients in the secukinumab every 2 weeks group, 17 [9%] in the secukinumab every 4 weeks group, and 15 [8%] in the placebo group) trials. No study-related deaths were reported up to week 16. The safety profile of secukinumab in both trials was consistent with that previously reported, with no new or unexpected safety findings detected.

INTERPRETATION

When given every 2 weeks, secukinumab was clinically effective at rapidly improving signs and symptoms of hidradenitis suppurativa with a favourable safety profile and with sustained response up to 52 weeks of treatment.

Patient Preferences in the Management of Hidradenitis Suppurativa: Results of a Multinational Discrete Choice Experiment in Europe

BACKGROUND AND OBJECTIVE

Hidradenitis suppurativa is a chronic inflammatory skin disease that can lead to a substantial reduction in quality of life. Recent studies revealed high levels of unmet care needs of patients with hidradenitis suppurativa, but their preferences in treatment decision making have scarcely been investigated. This study aimed to reveal which treatment attributes adult patients with HS in Europe consider most important in treatment decision-making.

METHODS

A discrete choice experiment was conducted with adult patients with hidradenitis suppurativa in Europe to reveal which treatment attributes are most important when making treatment decisions. Participants were presented with 15 sets of two treatment options and asked for each to choose the treatment they preferred. The treatments were characterized by six attributes informed by a prior literature review and qualitative research: effectiveness, pain reduction, duration of treatment benefit, risk of mild adverse event, risk of serious infection, and mode of administration. A random parameter logit model was used to estimate patients' preferences with additional subgroup and latent class models used to explore any differences in preferences across patient groups.

RESULTS

Two hundred and nineteen adult patients with hidradenitis suppurativa were included in the analysis (90% women, mean age 38 years). For all six treatment attributes, significant differences were observed between levels. Given the range of levels of each attribute, the most important treatment attributes were effectiveness (47.9%), followed by pain reduction (17.3%), annual risk of a mild adverse event (14.4%), annual risk of a serious infection (10.3%), mode of administration (5.3%), and duration of treatment benefit (4.8%). Higher levels of effectiveness, namely a 75% or 100% reduction in the abscess and inflammatory nodule count, were preferred over levels of effectiveness primarily investigated in randomized clinical trials of hidradenitis suppurativa (a 50% reduction). Results were largely consistent across subgroups and three latent class groups were identified.

CONCLUSIONS

This study revealed the most important treatment characteristics for patients with hidradenitis suppurativa that can help inform joint patient-physician decision making in the management of hidradenitis suppurativa. Designing future hidradenitis suppurativa treatments according to stated preferences, namely, to offer higher levels of effectiveness and pain improvement without higher risks of adverse events, may increase patients' treatment concordance and lead to improved disease management outcomes.

[Guidelines for the Management of Patients with Hidradenitis Suppurativa]

Hidradenitis suppurativa is a chronic and recurrent inflammatory dermatosis characterized by the presence of inflammatory nodules and abscesses in the apocrine gland-rich areas that may progress to suppurative fistulas and scars. Despite being considered one of the dermatological conditions with the greatest impact on patient quality of life, it is often underdiagnosed. Hidradenitis suppurativa, especially in its severe forms, is associated with numerous comorbidities, so a holistic and multidisciplinary perspective is crucial for the management of these patients. The therapeutic approach is complex and challenging. The medical treatment options are diverse and must be adapted to clinical presentation and disease severity. Surgical therapy should be considered as an adjuvant to medical treatment, particularly in refractory cases and in the presence of scars or anatomical and/or functional mutilation. These recommendations reflect the main aspects of the management of the patient with hidradenitis suppurativa and are addressed to all healthcare professionals who take part in their follow-up.

Real-World Findings on the Characteristics and Treatment Exposures of Patients with Hidradenitis Suppurativa from US Claims Data

INTRODUCTION

Hidradenitis suppurativa (HS) is a chronic, debilitating, and painful inflammatory skin disease that significantly and negatively impacts patients' quality of life. The prevalence of HS in the USA is estimated to be 0.10%, with worldwide reports suggesting a prevalence closer to 1%. There is limited real-world evidence available on the care of patients with HS. We aimed to evaluate the trends in clinical care and treatment in the patient population with HS in the USA in a real-world setting.

METHODS

A cohort study was conducted using claims data from IBM MarketScan Databases, including the US Commercial Claims and Encounters with Medicare Supplemental and Coordination of Benefits (CCAE+MDCR) database and IBM US Medicaid database.

RESULTS

The annual prevalence of HS increased from 0.06% (2008) to 0.14% (2017), and from 0.17% (2008) to 0.31% (2017) among CCAE+MDCR and Medicaid patients, respectively. Dermatologist visits increased from 31.9% (2008) to 47.8% (2019) in CCAE+MDCR patients, and decreased from 10.9% (2008) to 8.5% (2018) in Medicaid patients. Opioid use decreased from 45.4% (2008) to 25.5% (2019) among CCAE+MDCR patients, and from 71.3% (2008) to 48.1% (2018) among Medicaid patients. Only 8.4% of CCAE+MDCR patients and 5.8% of Medicaid patients were exposed to any biologic in 2018.

CONCLUSIONS

Improved care and treatment of HS over the last decade, including the emergence of new treatments, have been accompanied by an increase in awareness and reported prevalence of the disease. However, there are still gaps in access to dermatologic care and low utilization of biologic therapies among patients with HS. INFOGRAPHIC.

A Practical Guide for Primary Care Providers on Timely Diagnosis and Comprehensive Care Strategies for Hidradenitis Suppurativa

Hidradenitis suppurativa is a chronic, progressive inflammatory disease of the skin with many systemic implications. Hidradenitis suppurativa is frequently underdiagnosed or misdiagnosed, particularly because of heterogeneity in presentation and low disease recognition. Patients can see multiple types of health care providers, including primary care providers, along their journey to an accurate diagnosis. This review provides a comprehensive overview of the clinical presentation, associated comorbidities, and life impact associated with hidradenitis suppurativa. Disease features described here can facilitate earlier identification of hidradenitis suppurativa, differentiation from common mimickers, and timely referrals for multidisciplinary management when needed. Engagement of the medical community will also support comprehensive care strategies necessary in hidradenitis suppurativa.

Pain and Late-Onset of Hidradenitis Suppurativa Can Have a Negative Influence on Occupational Status and Educational Level. A Cross-Sectional Study

BACKGROUND AND OBJECTIVES

Hidradenitis suppurativa is a chronic and painful condition with negative impact on daily activity. Little information on the impact of disease-specific factors on educational level and occupational status in hidradenitis suppurativa patients has been reported. We sought to identify how disease-specific factors could influence occupational status and educational level in patients with hidradenitis suppurativa.

METHODS

Cross-sectional study of patients with hidradenitis suppurativa seen between September 2017 and September 2018. Disease-specific variables were analyzed to find associations in patients with different educational levels and occupational status.

RESULTS

Ninety-eight patients were included. Patients with non-university studies had more frequently≥3 affected areas (22.5% [16/73] vs 4.8% [1/22], p=0.049), a higher number of painful days (8.5 [SD 8.8] vs 4.6 [SD 4.8], p=0.048) and a higher score on the VAS scale (6.7 [SD 2.8] vs 5.0 [3.3], p=0.031). Patients from the inactive group had a significantly increased number of painful days (11.2 [SD 10.4] vs 5.7 [SD 6.2], p=0.004). This group had a greater number of patients with a history of depression (61.3% [19/31] vs 27.4% [17/62], p=0.002) and a higher mean BMI (32.3 [9.1] vs 28.4 [6.4], p=0.016). Late disease onset was significantly associated with being "inactive" (26.7% [8/31] vs 6.5% [4/62], p=0.026). No significant differences between severity scales of hidradenitis suppurativa and educational level or occupational status were found.

LIMITATIONS

cross-sectional and single center study.

CONCLUSIONS

Pain, ≥3 affected areas, history of depression, higher mean BMI, and late onset of hidradenitis suppurativa, are associated with low education level and inactive occupational status.

Rifampin-moxifloxacin-metronidazole combination therapy for severe Hurley stage 1 hidradenitis suppurativa: prospective short-term trial and 1-year follow-up in 28 consecutive patients

BACKGROUND

Severe Hurley stage 1 hidradenitis suppurativa (HS1) is a difficult-to-treat form of the disease.

OBJECTIVE

To assess the efficacy and tolerance of the oral combination of rifampin (10 mg/kg once daily)/moxifloxacin (400 mg once daily)/metronidazole (250-500 mg 3 times daily) (RMoM) treatment strategy in patients with severe HS1.

METHODS

Prospective, open-label, noncomparative cohort study in 28 consecutive patients. Nineteen patients were treated for 6 weeks by RMoM, followed by 4 weeks of rifampin/moxifloxacin alone, then by cotrimoxazole after remission. Moxifloxacin was replaced by pristinamycin (1 g 3 times daily) in 9 patients because of contraindications or intolerance. The primary endpoint was a Sartorius score of 0 (clinical remission) at week 12.

RESULTS

The median Sartorius score dropped from 14 to 0 (P = 6 × 10^-6) at week 12, with 75% of patients reaching clinical remission. A low initial Sartorius score was a prognosis factor for clinical remission (P = .049). The main adverse effects were mild gastrointestinal discomfort, mucosal candidiasis, and asthenia. At 1 year of follow-up, the median number of flares dropped from 21/year to 1 (P = 1 × 10^-5).

LIMITATIONS

Small, monocentric, noncontrolled study.

CONCLUSIONS

Complete and prolonged remission can be obtained in severe HS1 by using targeted antimicrobial treatments.

Can hidradenitis suppurativa patients classify their lesions by means of a digital lesion identification scheme?

BACKGROUND AND OBJECTIVES

Hidradenitis suppurativa (HS) differs widely with respect to its clinical presentation. Literature imposes different phenotypes potentially implying different treatment modalities. The aim of this study is to develop a validated scheme that enables HS patients to identify their own lesion types.

PATIENTS AND METHODS

The developed schemes for physicians and patients were implemented in a specific software. Upon patient consent, the physician used the software to document the lesions identified. Patients subsequently logged into the patient-version of the software from the convenience of their home and selected the lesions they identified on themselves. Afterwards the correlation between professionals and patients was tested.

RESULTS

For seven lesion types, correlation coefficients were statistically significant. A large/strong correlation between patients and physicians was found for the draining fistulas (0.59) and double-ended comedones (0.50). For five other lesion types, correlation was medium/moderate, namely the inflammatory nodule (0.37), abscess (0.30), accordion like-/ bridged scar (0.45), epidermal cyst (0.33) and pilonidal sinus (0.39).

CONCLUSIONS

HS-patients demonstrate high willingness to share their experiences and data. Therefore, a self-assessment scheme, as the developed LISAI, can be a valuable tool to enrich patient surveys with the identification of lesion types, for instance as a basis for phenotyping.

A Case Study of Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a complex, chronic, inflammatory skin disease that is often unrecognized or misdiagnosed. Patients frequently present to with painful nodules, inflammatory papules, sinus tracts, and scarring to intertriginous areas seeking care to alleviate symptoms. There is a paucity of information available specifically aimed to educate emergency nurse practitioners on how to recognize, diagnose, and treat this population. The article highlights the main diagnostic criteria and treatment options available for HS patients to help expand disease awareness.

Pain and late-onset of hidradenitis suppurativa can have a negative influence on occupational status and educational level. A cross-sectional study

BACKGROUND AND OBJECTIVES

Hidradenitis suppurativa (HS) is a chronic and painful condition with negative impact on daily activity. Little information on the impact of disease-specific factors on educational level and occupational status in hidradenitis suppurativa patients has been reported. We sought to identify how disease-specific factors could influence occupational status and educational level in patients with HS.

METHODS

Cross-sectional study of patients with HS seen between September 2017 and September 2018. Disease-specific variables were analyzed to find associations in patients with different educational levels and occupational status.

RESULTS

Ninety-eight patients were included. Patients with non-university studies had more frequently ≥ 3 affected areas (22.5% [16/73] vs. 4.8% [1/22], p = 0.049), a higher number of painful days (8.5 [SD 8.8] vs. 4.6 [SD 4.8], p = 0.048) and a higher score on the VAS scale (6.7 [SD 2.8] vs. 5.0 [3.3], p = 0.031). Patients from the inactive group had a significantly increased number of painful days (11.2 [SD 10.4] vs. 5.7 [SD 6.2], p = 0.004). This group had a greater number of patients with a history of depression (61.3% [19/31] vs. 27.4% [17/62], p = 0.002) and a higher mean BMI (32.3 [9.1] vs. 28.4 [6.4], p = 0.016). Late disease onset was significantly associated with being «inactive» (26.7% [8/31] vs. 6.5% [4/62], p = 0.026). No significant differences between severity scales of HS and educational level or occupational status were found.

LIMITATIONS

cross-sectional and single center study.

CONCLUSIONS

Pain, ≥ 3 affected areas, history of depression, higher mean BMI, and late onset of HS, are associated with low education level and inactive occupational status.

Integrating primary palliative care into hidradenitis suppurativa management

Hidradenitis suppurativa (HS) is a chronic, often debilitating skin condition that disproportionately impacts women in the United States and other Western nations. Dermatologists should consider incorporating palliative care principles into HS management to optimize care. Primary palliative care principles include utilizing evidence-based frameworks in serious illness communication, acknowledging and addressing physical and psychosocial suffering, recognizing and validating the burden of disease in partners, families, and caregivers, and engaging in collaborative care coordination. Certain patients may also benefit from outpatient, or sometimes inpatient, palliative care specialist collaboration, such as those with refractory HS and superimposed challenging psychosocial dynamics and symptom burden. Through integration of these palliative care domains into HS care, dermatologists can optimize their ability to provide comprehensive and compassionate care for patients suffering with this disease.

Pain measurement in painful skin conditions and rheumatoid arthritis randomized controlled trials: a scoping review to inform pain measurement in hidradenitis suppurativa

BACKGROUND

Pain is the most common and bothersome symptom experienced by people with hidradenitis suppurativa (HS) and has been prioritized as an outcome domain by the HIdradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC).

OBJECTIVES

To perform a scoping review of pain measurement in randomized control trials (RCTs) of painful skin conditions (PSCs) and use of the pain numerical rating scale (NRS) and visual analogue scale (VAS) in rheumatoid arthritis RCTs, to inform the efforts of HISTORIC to reach consensus on how to measure pain intensity in HS trials.

METHODS

A search was conducted on several publication databases. Inclusion criteria were RCTs with a minimum of 10 participants that measured pain intensity.

RESULTS

Pain NRS and VAS were used in 68% of PSC trials. Respectively, 77% and 87% of PSC and rheumatoid arthritis RCTs did not specify the recall window. The commonest recall window in PSCs when specified was 24 h. In total, 33% of PSC trials assessed maximum pain intensity and 3% average pain intensity, while 87% of rheumatoid arthritis trials did not provide details. Pain data were reported as mean difference by 76% of PSC trials and 75% of rheumatoid arthritis trials. Respectively, 10% and 11% of PSC and rheumatoid arthritis studies reported pain as the percentage of patients reaching a desirable state and only 1% and 2% reported number needed to treat.

CONCLUSIONS

While pain NRS and VAS are standard methods to measure pain intensity in PSCs, key details such as the recall window are often omitted and there is no consensus on how to report pain NRS data. What is already known about this topic? Pain is the most burdensome symptom experienced by patients with hidradenitis suppurativa and has been prioritized as an outcome domain by the HIdradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC). What does this study add? Our review shows substantial variation in how pain numerical rating scale (NRS) and visual analogue scale are utilized in clinical trials. This variation restricts meta-analysis of pain intensity results. There is a need for consensus regarding the recall window for pain NRS and maximum vs. average pain, and whether current pain should be measured.

Factors associated with treatment satisfaction in patients with hidradenitis suppurativa: results from the Global VOICE project

BACKGROUND

Nearly half of patients with hidradenitis suppurativa (HS) report dissatisfaction with their treatment. However, factors related to treatment satisfaction have not been explored.

OBJECTIVES

To measure associations between treatment satisfaction and clinical and treatment-related characteristics among patients with HS.

METHODS

Treatment satisfaction was evaluated utilizing data from a cross-sectional global survey of patients with HS recruited from 27 institutions, mainly HS referral centres, in 14 different countries from October 2017 to July 2018. The primary outcome was patients' self-reported overall satisfaction with their current treatments for HS, rated on a five-point scale from 'very dissatisfied' to 'very satisfied'.

RESULTS

The final analysis cohort comprised 1418 patients with HS, most of whom were European (55%, 780 of 1418) or North American (38%, 542 of 1418), and female (85%, 1210 of 1418). Overall, 45% (640 of 1418) of participants were either dissatisfied or very dissatisfied with their current medical treatment. In adjusted analysis, patients primarily treated by a dermatologist for HS had 1·99 [95% confidence interval (CI) 1·62-2·44, P < 0·001] times the odds of being satisfied with current treatment than participants not primarily treated by a dermatologist. Treatment with biologics was associated with higher satisfaction [odds ratio (OR) 2·36, 95% CI 1·74-3·19, P < 0·001] relative to treatment with nonbiologic systemic medications. Factors associated with lower treatment satisfaction included smoking (OR 0·78, 95% CI 0·62-0·99; active vs. never), depression (OR 0·69, 95% CI 0·54-0·87), increasing number of comorbidities (OR 0·88 per comorbidity, 95% CI 0·81-0·96) and increasing flare frequency.

CONCLUSIONS

There are several factors that appear to positively influence satisfaction with treatment among patients with HS, including treatment by a dermatologist and treatment with a biologic medication. Factors that appear to lower treatment satisfaction include active smoking, depression, accumulation of comorbid conditions and increasing flare frequency. Awareness of these factors may support partnered decision making with the goal of improving treatment outcomes. What is already known about this topic? Nearly half of patients with hidradenitis suppurativa report dissatisfaction with their treatments. What does this study add? Satisfaction with treatment is increased by receiving care from a dermatologist and treatment with biologics. Satisfaction with treatment is decreased by tobacco smoking, accumulation of comorbid conditions including depression, and higher flare frequency. What are the clinical implications of this work? Awareness of the identified factors associated with poor treatment satisfaction may support partnered decision making and improve treatment outcomes.

Racial disparities of delay in diagnosis and dermatologic care for hidradenitis suppurativa

Hidradenitis suppurativa is a chronic, debilitating skin disease that disproportionately affects African Americans, and care-related factors may contribute to this disparity. In this study, we investigated delay in diagnosis and dermatologic care for HS at an urban Midwestern Academic Center. A retrospective chart review of 1,190 patients with 3 or more encounters for HS between 1/1/2002 and 3/19/2019 was conducted. A total of 953 patients were included in statistical analysis. A mean (standard deviation) delay in diagnosis was 4.1 ± 7.0 years. For white patients the delay in diagnosis was 3.2 ± 6.3 years, for Black patients 4.8 ± 7.0 years, for Hispanic patients 4.7 ± 5.8 years, and for other races 4.9 ± 7.4 years (p <0.001). Among the 932 patients with known specialist visit types, 500 (53.6%) had seen dermatology including 222 (47.8%) of Black patients, 242 (59.5%) of white patients, 24 (64.9%) of Hispanic patients, and 12 (50%) patients of other races (p=0.003).White patients and Hispanic patients saw a dermatologist an average of 3.0 years after first presentation of HS and Black patients saw a dermatologist on average 5.0 years after first presentation (p=0.004). Of the patients who did see dermatology, 44.9% of Black patients, 31.6% of white patients, 23.1% of Hispanic patients, and 30.8% of other races saw surgery before dermatology (p<.001). Our results indicate that non-white patients have a longer delay in diagnosis than their white counterparts and that Black patients do not see dermatology as early in their disease course as other racial groups. Black patients also see surgery more often than white patients before seeing dermatology, which could suggest greater disease severity at presentation and diagnosis or difficult access to dermatology.

Factors Associated With Dermatologic Follow-up vs Emergency Department Return in Patients With Hidradenitis Suppurativa After an Initial Emergency Department Visit

Importance

Emergency department (ED) visitation is common for the treatment of hidradenitis suppurativa (HS), whereas dermatology outpatient care is low. The reasons underlying this differential follow-up have not been elucidated.

Objective

To assess the interventions and patient factors associated with ED return following an initial ED visit for HS.

Design, Setting, and Participants

This retrospective cohort study used data from the IBM® MarketScan® Commercial and Multi-State Medicaid databases (trademark symbols retained per database owner requirement). An HS cohort was formed from patients who had 2 or more claims for HS during the study period of 2010 to 2019 and with at least 1 ED visit for their HS or a defined proxy. Data were analyzed from November 2021 to May 2022.

Exposures

Factors analyzed included those associated with the ED visit and patient characteristics.

Main Outcomes and Measures

Primary outcomes were return to the ED or dermatology outpatient follow-up for HS or related proxy within 30 or 180 days of index ED visit.

Results

This retrospective cohort study included 20 269 patients with HS (median [IQR] age, 32 [25-41] years; 16 804 [82.9%] female patients), of which 7455 (36.8%) had commercial insurance and 12 814 (63.2%) had Medicaid. A total of 9737 (48.0%) patients had incision and drainage performed at the index ED visit, 14 725 (72.6%) received an oral antibiotic prescription, and 9913 (48.9%) received an opioid medication prescription. A total of 3484 (17.2%) patients had at least 1 return ED visit for HS or proxy within 30 days, in contrast with 483 (2.4%) who had a dermatology visit (P < .001). Likewise, 6893 (34.0%) patients had a return ED visit for HS or proxy within 180 days, as opposed to 1374 (6.8%) with a dermatology visit (P < .001). Patients with Medicaid and patients who had an opioid prescribed were more likely to return to the ED for treatment of their disease (odds ratio [OR], 1.48; 95% CI, 1.38-1.58; and OR, 1.48; 95% CI, 1.39-1.58, respectively, within 180 days) and, conversely, less likely to have dermatology follow-up (OR, 0.16; 95% CI, 0.14-0.18; and OR, 0.81; 95% CI, 0.71-0.91, respectively, within 180 days).

Conclusions and Relevance

This cohort study suggests that many patients with HS frequent the ED for their disease but are not subsequently seen in the dermatology clinic for ongoing care. The findings in this study raise the opportunity for cross-specialty interventions that could be implemented to better connect patients with HS to longitudinal care.

Hidradenitis Suppurativa: The Influence of Gender, the Importance of Trigger Factors and the Implications for Patient Habits

Hidradenitis suppurativa (HS) is a debilitating, chronic, inflammatory skin disease primarily affecting apocrine gland-rich areas of the body. On the one hand, the presence of triggering factors-some identified, others only hypothesized-may initiate or perpetuate the pathogenic process of HS. In addition to cigarette smoking and diet, other trigger factors, including choice of clothing, are frequently observed in clinical practice. On the other hand, the presence of disease may influence habits of HS patients. Indeed, high incidences of sexual and sleep impairment have been reported in these patients. Consequently, alcohol and substance abuse may be a coping strategy for the emotional and psychological disease burden. Furthermore, a greater awareness of gender differences in HS may be important for dermatologists in their own clinical practice (i.e., pregnancy and breastfeeding). Consequently, in this loop interaction, comprehensive knowledge of all factors involved is crucial for the management of HS patients. Thus, the objective of this review is to (i) discuss the influence of gender on HS, (ii) summarize the most frequent triggering factors of HS and (iii) analyze the impact of HS on patient habits.

Hidradenitis Suppurativa: Diagnosis and Management in the Emergency Department

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic immune-mediated inflammatory skin disease characterized by abscesses and inflammatory nodules, and occasionally tunnels and scars, in the axillae, groin, and inframammary areas.

OBJECTIVE

HS can be challenging to diagnose because it mimics localized soft-tissue infection. The process of differentiating HS from soft-tissue infection is discussed. Patients with HS frequently visit emergency departments (EDs) for acute management of pain and drainage from HS lesions. This review updates emergency and urgent care physicians on how to educate and initiate treatment for patients with HS, and to coordinate care with dermatologists and other physicians early in their disease course.

DISCUSSION

Recent updates on the epidemiology, diagnosis, and management of HS are reviewed.

CONCLUSIONS

Practice variations between how care for HS is provided in the ED setting and what HS treatment guidelines recommend are identified.

African American race is a risk factor for severe hidradenitis suppurativa

BACKGROUND

African Americans face a disproportionate incidence and prevalence of hidradenitis suppurativa (HS) in the United States, but HS severity and outcomes across racial and ethnic groups have not been well-established while controlling for potentially confounding factors. In this retrospective cohort study, we investigated the associations of race and ethnicity with HS severity, emergency department (ED) visits, hospitalizations, and surgeries for HS while controlling for age, sex, body mass index (BMI), tobacco use, and insurance type.

METHODS

We reviewed 1190 patients seen at the Medical College of Wisconsin with ≥3 encounters for HS between 1/1/2002 and 3/19/2019, excluding those without race data or an encounter in which HS was treated.

RESULTS

A total of 953 patients were included; 470 patients were Black or African American non-Hispanic (49%), 39 Hispanic (4%), 418 White non-Hispanic (44%), and 26 other race or ethnicity (3%). Controlling for age, sex, BMI, tobacco use, and insurance type, Black patients had 2.8 times the odds of having Hurley stage III disease (95% CI 1.76-4.45, P < 0.001), 2.86 times the risk for experiencing an ED visit for HS (95% CI 2.12-3.88, P < 0.001), 2.25 times the risk for experiencing a hospitalization for HS (95% CI 1.42-3.56, P < 0.001), and 1.61 times the risk for experiencing a surgical encounter for HS (95% CI 1.34-1.95, P < 0.001) when compared to White patients.

CONCLUSIONS

African Americans face significant disparities in HS severity, ED visits, hospitalizations, and surgeries. The causes of these disparities must be further investigated and addressed.

IL-17A is a pertinent therapeutic target for moderate-to-severe hidradenitis suppurativa: Combined results from a pre-clinical and phase II proof-of-concept study

Hidradenitis Suppurativa (HS) is a chronic, recurrent, inflammatory, follicular skin disease whose pathology is complex and not fully understood. The objective of this study was to elucidate the role of IL-17A in moderate-to-severe HS. Transcriptomic and histological analyses were conducted on ex vivo HS (n = 19; lesional and non-lesional) and healthy control (n = 8) skin biopsies. Further, a Phase II exploratory, randomized, double-blind, placebo-controlled study was carried out in moderate-to-severe HS patients. Patients were treated with either CJM112 300 mg (n = 33), a fully human anti-IL-17A IgG1/κ monoclonal antibody, or placebo (n = 33). The main outcome of the translational analyses was to identify IL-17A-producing cells and indications of IL-17A activity in HS lesional skin. The primary objective of the clinical study was to determine the efficacy of CJM112 in moderate-to-severe HS patients by HS-Physician Global Assessment (HS-PGA) responder rate at Week 16. Transcriptomic and histopathologic analyses revealed the presence of heterogeneous cell types in HS lesional skin; IL-17A gene signatures were increased in HS lesional vs non-lesional or healthy skin. High expression of IL-17A was localized to T cells, neutrophils, and mast cells, confirming the transcriptional data. Clinically, the proportion of Week 16 HS-PGA responders was significantly higher (p = 0.03) in the CJM112 group vs placebo (32.3% vs 12.5%). This study elucidated the role of the IL-17A pathway in HS pathogenesis and clinically validated the IL-17A pathway in moderate-to-severe HS patients in a proof-of-concept study using the anti-IL-17A-specific antibody CJM112.

Practical Guidelines for Managing Patients With Hidradenitis Suppurativa: An Update

Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease that is characterized by the formation of comedones, papules, nodules, abscesses and sinus tracts in the axillary, inframammary, groin, and gluteal areas. Up to 3.8% of the Canadian population has HS, though due to a lack of awareness of HS, many patients are initially misdiagnosed and do not receive adequate treatment early on in the disease course. Once a diagnosis of HS is made, developing an effective management plan can be a dilemma for many providers. There is significant variability in response to any given therapy within the HS patient population and many HS patients have other medical comorbidities which must be taken into consideration. The aim of this review is to provide a practical approach for all healthcare providers to diagnose and manage HS and its associated comorbidities. A sample electronic medical record template for HS management was developed by the Canadian Hidradenitis Suppurativa Foundation Executive Board and is intended for use in clinical settings. This will help to increase collaboration between primary healthcare providers, dermatologists, and other medical specialists and ultimately improve the quality of care that HS patients receive.

The impact of hidradenitis suppurativa on quality of life is worse than inflammatory bowel disease and myocardial infarction

Quality of life is severely impacted by Hidradenitis Suppurativa. This cross-sectional survey based study highlights that the impact of Hidradenitis Suppurativa on quality of life measured by the World Health Organisation Quality of Life (WHOQOL-BREF) survey is worse than published data for atopic dermatitis and other acute and chronic medical conditions including myocardial infarction and inflammatory bowel disease.

Real-World Considerations of Candidacy for Biologics in Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic, progressive inflammatory skin disease that is often recalcitrant to multiple treatments. In determining biologic candidacy for patients with HS, we propose a paradigm shift away from Hurley staging and towards consideration of other variables. Biologics represent a long-term treatment option for HS that may serve as a disease-modifying agent. These medications are typically initiated in patients with moderate to severe disease, which, based on inclusion criteria in clinical trials, is often defined as Hurley stage II or III disease, at which point irreversible tissue damage has already occurred. In real-world clinical settings, these considerations include treatments tried and failed, predicted disease trajectory, disease characteristics beyond lesion type, impact of disease on patients' functional status and quality of life, and patient comorbidities, venturing away from the limitations of Hurley stage designations. Future clinical trials may benefit from inclusion of recalcitrant Hurley stage I patients, which may then re-shape treatment guidelines and insurance coverage and improve patient access to biologic treatments.

Development and initial validation of the HS-IGA: a novel hidradenitis suppurativa-specific investigator global assessment for use in interventional trials

BACKGROUND

Few validated instruments exist for use in hidradenitis suppurativa (HS) trials.

OBJECTIVES

To develop a novel HS Investigator Global Assessment (HS-IGA) and to validate its psychometric properties.

METHODS

Development of HS-IGA involved discussion among stakeholders, including patients, within HISTORIC. Data from replicate phase III randomized controlled trials evaluating HS treatment were utilized. Multivariate models identified lesion type and body region as variables of importance. Classification and regression trees for ordinal responses were built. Validation included assessment of test-retest reliability, predictive validity, responsiveness and clinical meaningfulness.

RESULTS

There were 3024 unique measurements available in PIONEER I. Mean and median lesion counts by region were largely <10 and were highest in axillary and inguinal regions. The mean and median number of regions involved were ≤ 3 for individual lesions and combinations. Regardless of lesion type, axillary and inguinal regions most influenced the HS-IGA score. Accordingly, regions were combined into a six-point IGA based on the maximum lesion number in either upper or lower body regions with a score of 0 (0-1 lesions), 1 (2-5), 2 (6-10), 3 (11-15), 4 (16-20) and 5 (≥ 20 lesions). The intraclass correlation coefficient for test-retest reliability was 0·91 (95% confidence interval 0·87-0·94). Spearman's rank order correlations (SROCs) with HS-PGA and Hidradenitis Suppurativa Clinical Response (HiSCR) were 0·73 and 0·51, respectively (P < 0·001 for both comparisons). SROCs with Dermatology Life Quality Index (DLQI), pain numerical rating scale and HS-QoL were 0·42, 0·34 and -0·25, respectively (P < 0·001 for all comparisons). HS-IGA was responsive at weeks 12 and 36. Predictive convergent validity was very good with HS-PGA (area under the curve = 0·89) and with HiSCR (area under the curve = 0·82). Predictive divergent validity was low with DLQI and HS-QoL.

CONCLUSIONS

HS-IGA has moderate-to-strong psychometric properties and is simple to calculate.

A systematic review and meta-analysis of sexual dysfunction in patients with hidradenitis suppurativa

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition associated with significant psychosocial comorbidity. To date, the relationship between HS and sexual dysfunction has not been assessed through meta-analysis. A systematic review was performed by OVID Medline, EMBASE, Cochrane Central, PsycINFO via EBSCO, Web of Science, and LILACS. Original English language studies assessing HS and sexual function published prior to April 2020 were screened. Scores from the Female Sexual Function Index (FSFI), International Index of Erectile Function (IIEF), Arizona Sexual Experiences Scale (ASEX), Frankfurt Self-Concept Scale for Sexuality (FKKS SEX), and Dermatology Life Quality Index (DLQI) were analyzed. Sixteen studies met inclusion criteria, and nine were eligible for meta-analysis. Pooled mean FSFI score for female HS patients met criteria for sexual dysfunction (mean = 20.32, P < 0.001). Females with HS reported worse FSFI scores than controls (pooled mean difference = -5.704, P = 0.003, I² =0). Mean IIEF score among males with HS was 47.96 (P < 0.001). Males with HS also reported worse IIEF scores than controls (pooled mean difference = -18.77, P = 0.00, I²  = 0). Females with HS performed worse on sexual function inventories than males with HS (SMD = -0.72, P = 0.009, I²  = 0). Both male and female HS patients reported significantly more sexual impairment than same-sex controls. Female HS patients also experience more sexual impairment than males and on average meet criteria for sexual dysfunction (FSFI <26.55). Clinicians should be aware that their patients with HS, especially females, may be suffering from sexual dysfunction and treated them appropriately.

Interviewing Women with Hidradenitis Suppurativa-Thematic and Content Analysis

OBJECTIVE

Hidradenitis suppurativa (HS) is a chronic autoinflammatory skin disease with a higher prevalence in women. The disease results in a low quality of life as well as physical and psychological comorbidities. The authors sought to determine the effects of HS on women's self-perception and life experiences.

METHODS

Semistructured interviews were conducted with 22 women of varying age and family status. The content was transcribed and subjected to both thematic and content analyses.

RESULTS

Five themes and a number of subthemes were revealed, involving physical, emotional, coping, and functional aspects. Somatic features, especially pain, were the most troubling issues, along with the emotional burden of shame and loss of femininity and intimacy. However, women also revealed strength and expressed optimism.

CONCLUSIONS

These findings reveal the inner world of women coping with HS, addressing multiple dilemmas, problems, and concerns. Healthcare providers should pay special attention to the specific needs of these patients. Additional research is needed to further shed light on the impact of HS on women.

Hidradenitis Suppurativa in the United States: Insights From the National Inpatient Sample (2008-2017) on Contemporary Trends in Demographics, Hospitalization Rates, Chronic Comorbid Conditions, and Mortality

Background Hidradenitis suppurativa (HS) is a clinical condition characterized by the formation of painful lumps under the skin. It often affects intertriginous areas like armpits and groin. There is a paucity of contemporary data on patient and hospital-level characteristics of HS in the United States. Methods We analyzed the Nationwide Inpatient Sample (NIS) for retrospective analysis to calculate the frequency and yearly rates of HS hospitalizations, demographic variations, rates of comorbidities, and length of stay. Results The rate of hospitalizations with HS as a primary diagnosis increased from 7.9 per 100,000 all-cause hospitalizations in 2008 to 11.6 per 100,000 all-cause hospitalizations in 2017 (p < 0.0001). The mean age ± standard error of hospitalized patients was 39.5 ± 0.2 years. The age group of 18-34 years was the most affected. Women showed a higher preponderance of the disease than men (56.6% vs. 43.5%, p < 0.0001). The Black race was the most affected out of all the racial groups (59.9%). Most hospitalizations were in large, urban teaching hospitals. Hypertension (34.9%), skin and subcutaneous tissue infections (26.5%), and diabetes mellitus (25.9%) were the most common comorbidities. Out of the total hospitalizations with HS, 12.7% were found to have a major or extreme loss of function and 3.5% were at a major or extreme likelihood of dying. Conclusions HS disproportionately affects young adults, women, and Black patients. A significant proportion of these patients are at a major risk of major loss of bodily function or death. Prospective studies are needed to identify the risk factors for hospitalizations in these patient populations and devise appropriate prevention and treatment strategies.

Unmet clinical needs and burden of disease in hidradenitis suppurativa: Real-world experience from EU5 and US

Background

Hidradenitis suppurativa (HS) is a chronic, inflammatory, debilitating skin disease characterized by painful deep lesions and associated with substantial disease burden.

Objectives

The objective of this study was to describe physician‐ and patient‐reported clinical unmet needs from a real‐world perspective.

Methods

This study used data from the Adelphi HS Disease Specific Programme, a point‐in‐time survey of dermatologists and their patients with HS in Europe and the United States. Dermatologists completed patient record forms (PRFs) for 5–7 consecutively consulting patients with HS; patients or carers of patients also optionally completed a patient/carer self‐completion questionnaire (PSC/CSC). Data collection included demographics, symptomatology and impact on quality of life (QoL).

Results

Dermatologists (N = 312) completed PRFs for 1787 patients with HS; patient‐ and carer‐reported questionnaires (PSC/CSC) were completed for 33.1% (591/1787) of patients. The mean age was 34.4 ± 12.2 years and 57.6% of patients were female (1029/1787). Physician‐judged disease severity at sampling was categorized as mild in 66.0% (1179/1787), moderate in 29.3% (523/1787) and severe in 4.7% (85/1787) of patients. Deterioration or unstable condition over the previous 12 months was described by 17.1% [235/1372] and 12.6% [41/325] of physician‐ and patient/carer‐reported cases, respectively. Despite receiving treatment, high proportions of patients still experienced symptoms at sampling (general pain/discomfort [49.5%, 885/1787]; inflammation/redness of lesions/abscesses [46.1%, 823/1787] and itching [29.9%, 535/1787]); these symptoms were more frequent in patients with moderate or severe disease. Patients reported a mean Dermatology Life Quality Index score of 5.9 ± 5.4 (555/591; mild, 4.1 ± 4.3; moderate, 9.4 ± 5.4; severe, 13.3 ± 5.5) and a mean Hidradenitis Suppurativa Quality of Life score of 11.0 ± 10.6 (518/591; mild, 7.6 ± 8.3; moderate, 17.7 ± 10.0; severe, 31.0 ± 15.4) indicating a substantial impact on QoL.

Conclusions

Patients with HS experienced a high disease burden despite being actively treated by a dermatologist. This study demonstrates that the burden of HS disease is generally poorly managed with a considerable impact observed on patients' QoL.

Diagnosing and Managing Hidradenitis Suppurativa in Pediatrics

Hidradenitis suppurativa (HS) is a debilitating chronic inflammatory skin disease that presents as exquisitely tender abscesses, draining fistulae, and sinus tracts. HS can lead to significant impairments in patients' quality of life, especially for children and adolescents who face challenges related to self-esteem and physical and emotional development. Severe long-term physical sequelae of inadequately treated HS include extensive scarring, urogenital strictures, immobility, and squamous cell carcinoma; emotional sequelae include depression, anxiety, and suicidal ideation. Many of the devastating long-term sequelae associated with HS can be prevented with early recognition and proper collaborative management. This article reviews strategies to aid pediatricians in early diagnosis of HS and provides clinical pearls for management and prevention of disease flares. [Pediatr Ann. 2022;51(3):e123-e127.].
