Psychophysical aspects of hidradenitis suppurativa

Risk of cardiovascular disorders in hidradenitis suppurativa patients: a large-scale, propensity-matched global retrospective cohort study

BACKGROUND

Patients with hidradenitis suppurativa (HS) often suffer from comorbid diabetes, metabolic syndrome, and hyperlipidemia and, therefore, are susceptible to the development of cardiovascular diseases (CVDs). Moreover, systemic inflammation plays a vital role in the development of atherosclerosis. The creation of atherosclerotic plaque is characterized by endothelial dysfunction driven by elevated concentrations of interleukin (IL)-1, IL-6, and IL-18 among others, as well as tumor necrosis factor (TNF) alpha.

METHODS

This study aimed to assess the risk of HS patients developing CVDs. We performed a large-scale, propensity-matched global retrospective cohort study analyzing the risk of development of CVDs in patients suffering from HS. The analysis included 144,100 HS patients with 144,100 healthy controls (HC). The cohorts were matched regarding demographics and history of diseases relevant to CVDs, e.g., diabetes, obesity, and nicotine dependence. A total of 90 cardiovascular disorders were identified. The identification of cardiovascular disorders was based on ≥1% appearance of the event, based on absolute numbers, in both cohorts.

RESULTS

Before the matching, HS patients displayed a higher frequency in excess weight or obesity (25 vs. 14.4%, respectively), nicotine dependence, and diabetes mellitus, but lower odds of primary hypertension in comparison to healthy controls. A total of 47 CVDs are associated with an increased risk of onset in HS patients. Although the highest hazard ratio (HR; 2.1; 95% CI: 1.95-2.269) was found for unspecified heart failure, the HS cohort was exceptionally predisposed to developing myocardial infarction (HR: 2.06; 95% CI: 1.88-2.27) and an acute embolism and deep vein thrombosis of the lower extremity (HR: 1.93; 95% CI: 1.74-2.14).

CONCLUSIONS

This is the most extensive study on the association of HS with CVDs. We demonstrated that HS patients are at significantly greater risk of developing various CVDs compared to matched controls, with heart failure being the most common one.

Psychiatric Influences on Hidradenitis Suppurativa: A Call for Help

Background  Hidradenitis suppurativa (HS) is associated with a high prevalence of psychiatric disorders. However, no studies examine how psychiatric disorders influence surgical and financial outcomes. This study aimed to assess impact of a psychiatric diagnosis on patients treated for HS. Methods  Patients with HS were retrospectively identified at a single institution from 2010 to 2021. Cohorts were stratified by the presence of a psychiatric disorder. Demographics, comorbidities, and disease characteristics were collected. Outcomes assessed included the procedural interventions and emergency department (ED) visits. Financial distress was assessed via the COST-FACIT Version 2 survey. Results  Out of 138 patients, 40 (29.0%) completed the survey of which 19 (47.5%) had a preexisting psychiatric diagnosis. No demographic differences were found between cohorts. Mean follow-up was 16.1 ± 11.0 months. The psychiatric cohort had a higher median number of surgeries received (7.0 vs. 1.5, p  < 0.001), a higher median number of ED visits (1.0 vs. 0, p  = 0.006), and a similar hospital length of stay ( p  = 0.456). The mean COST-FACIT score of the overall study population was 19.2 ± 10.7 (grade 1 financial toxicity). The psych cohort had a lower mean COST-FACIT score (16.8 vs. 21.3, p  = 0.092) and reported greater financial hardship (3.3 vs. 1.7, p  < 0.001). On multivariate analysis, a psychiatric diagnosis was predictive of lower credit scores, more ED visits, and a higher number of surgeries. Conclusion  Preexisting psychiatric conditions in patients with HS are associated with increased health care utilization and surgical intervention with substantial financial distress. Plastic surgeons should be cognizant of such comorbid disorders to facilitate holistic care addressing all patient needs.

Psychosocial effects of hidradenitis suppurativa in the literature: A systematic review

Hidradenitis suppurativa (HS) is an inflammatory disorder characterized by painful, deep follicular nodules, abscesses, sinus tracts, and scarring, most commonly presenting in the inguinal, axillary, and anogenital regions. This condition substantially decreases quality of life in affected individuals, resulting in higher rates of psychiatric disorders including depression, anxiety, suicidality, and substance use. The detrimental effects of HS are well documented by dermatologists, as individuals with HS make up a large proportion of the patients that they see daily. However, it is unclear whether psychiatrists are aware of the degree of psychosocial impairment present in HS patients. It is important that those in the field of psychiatry and behavioral medicine are aware of this condition and are comfortable managing it from a psychosocial perspective. This systematic review chronicles the existing literature on the psychosocial effects of HS and assesses the extent to which dermatology journals review these effects in comparison to psychiatry or behavioral medicine.

The NLRP3 Inflammasome Gene Is Overexpressed in Hidradenitis Suppurativa Lesions: A Preliminary Study on the Role of Pyroptosis in Disease Pathogenesis

Hidradenitis suppurativa (HS) is a debilitating inflammatory skin disorder, and its pathogenesis remains incompletely understood. This study aimed to investigate the role of the P2X7 receptor (P2X7R) and NLRP3 inflammasome in HS pathogenesis. RNA sequencing and real-time PCR were performed to assess the gene expression levels of P2X7R and NLRP3 in the skin biopsies of HS patients and healthy controls (HC). The results of our study revealed a significantly increased expression of the NLRP3 gene in both the lesional and perilesional skin of HS patients compared to healthy controls. Moreover, the mRNA levels of NLRP3 were significantly higher in lesional skin compared to non-lesional skin in HS patients, indicating the spread of inflammation to adjacent tissues. In contrast, no significant differences in P2X7R gene expression were observed between the three groups. These findings suggest the involvement of NLRP3 inflammasomes in HS pathogenesis, while P2X7R may not play a significant role in the disease. This research sheds light on the complex inflammatory pathways in HS, highlighting the potential of NLRP3 as a therapeutic target. Understanding the molecular mechanisms underlying HS is crucial for the development of targeted treatment modalities for this debilitating condition.

Hidradenitis Suppurativa Is Associated with Severe Sexual Impairment

INTRODUCTION

Hidradenitis suppurativa (HS) is a chronic inflammatory disorder of the pilosebaceous unit, often affecting and deforming intimate regions. HS is associated with severe pain, pruritus, and constant, purulent, malodorous discharge expected to impair sexual health of patients.

METHODS

We performed a cross-sectional, multicentric study involving 199 German patients from the health services research project "Epidemiology and Care in Acne inversa (EpiCAi)." The sexual health, HS severity, and quality of life of the studied group were evaluated using a specially designed questionnaire.

RESULTS

Regardless of gender, HS has an enormous impact on patients' sexual health. The patients scored, on average, 28.8 ± 5.3 points on the Relation and Sexuality Scale (RSS). Multiple linear regression revealed that females and patients with Hurley III stage had higher sexual dysfunction (p = 0.012). Sexual dysfunction is associated with pain (β = 0.25), the number of active lesions, the affected areas (β = 0.14), and psychosocial aspects, including low quality of life (β = 0.404), stigmatization (β = 0.411), depression (β = 0.413), and anxiety (β = 0.300). Patients already see a substantial decrease in sexual frequency in the early stages of HS, while functional impairment and fear increase with the severity of the disease.

CONCLUSION

Sexual health and management of its dysfunctions should be part of a holistic approach to HS patients.

Females May Have Less Severe Acne, but They Suffer More: A Prospective Cross-Sectional Study on Psychosocial Consequences in 104 Consecutive Polish Acne Patients

Acne is a common skin condition affecting both adolescents and adults, and it can profoundly impact patients' quality of life and mental well-being. This prospective cross-sectional study aims to explore the differences in psychosocial aspects between male and female acne patients in Poland. A total of 104 consecutive acne patients were included in this study. Clinical severity, patients' quality of life, stigmatization levels, and psychiatric disturbances were evaluated using the following instruments: Investigator Global Assessment (IGA), Dermatology Life Quality Index (DLQI), Cardiff Acne Disability Index (CADI), 6-Item Stigmatization Scale (6-ISS), and Hospital Anxiety and Depression Scale (HADS). This study found that female patients exhibited significantly less severe acne and experienced significantly decreased quality of life and increased levels of stigmatization. Furthermore, anxiety levels among female patients exceeded those observed in their male counterparts. Notably, no disparities in the severity of depression were observed between the two gender groups. Correlations were discerned among all psychosocial parameters in the entire study cohort and in the female subgroup, while such correlations were not uniformly observed among male participants. This study underscores the importance of considering psychosocial aspects and implementing routine measurements in the management of acne to improve patients' well-being.

Navigating the Multidimensional Impact of Living with Hidradenitis Suppurativa: An In-Depth Netnographic Study on Social Media Platforms

INTRODUCTION

Hidradenitis suppurativa (HS) is a chronic skin condition causing considerable distress. It impacts mobility, social interaction, and quality of life. In Brazil, there is a notable gap in epidemiological data and patient experiences regarding HS.

METHODS

This study, spanning 2019 to 2022, employed netnography to probe the experiences of Brazilian patients with HS. This approach gleans insights from online interactions, offering a direct view into patients' lives.

RESULTS

Notably, the data illuminated the challenges patients face, such as difficulties in obtaining a diagnosis and the complexities involved in managing a chronic, and often debilitating, condition. Furthermore, patients' experiences with various treatments, encompassing antibiotics, biologic agents, lifestyle alterations, surgical procedures, and alternative remedies, were also examined.

CONCLUSION

By undertaking a longitudinal analysis of patient interactions, the study aimed to offer a richer understanding of HS, from its diagnosis to its treatment. It underscores the necessity for a more patient-centered approach when managing this condition. We hope that this enhanced understanding can facilitate better care for those affected by HS.

Neutrophilic dermatosis and hidradenitis suppurativa in patients with Behçet's disease: A neutrophilic disease in the spectrum of autoinflammatory syndromes

BACKGROUND

Association of neutrophilic dermatosis (ND), hidradenitis suppurativa (HS) and Behçet's disease (BD) and shared efficacy of TNFα axis blockade suggests common physiopathology.

OBJECTIVES

To investigate the clinical features and therapeutic response of ND and HS associated with BD.

METHODS

We identified 20 patients with ND or HS associated with BD among 1462 patients with BD.

RESULTS

We analysed 20 (1.4%) patients diagnosed with ND or HS associated with BD: 13 HS, 6 pyoderma gangrenosum (PG), and 1 SAPHO. Our 6 PG cases over 1462 BD patients accounts for 400/100 000 prevalence. Thirteen had bipolar aphthosis, 6 vascular, 5 neurologic, and 4 ocular involvements. All PG occurred on limbs and had typical histology with constant dermal neutrophilic infiltrate. All HS had the classical axillary-mammary phenotype. Sixty-nine percent (69%) of HS were Hurley 1 stage. Treatment consisted mainly in colchicine (n = 20), glucocorticoids (n = 12), and anti-TNFα (n = 9). Interesting results with complete or partial responses were obtained with anti-TNFα (9 cases), ustekinumab (3 cases) and tocilizumab (1 case) to treat refractory ND or HS associated with BD.

CONCLUSION

PG seems overrepresented in patients with BD. Biotherapies such as anti-TNFα, ustekinumab and tocilizumab appear to be promising to treat refractory ND or HS associated with BD.

Stigmatization, a social perception which may have a debilitating impact on hidradenitis suppurativa patients: an observational study

Hidradenitis suppurativa (HS) is a debilitating disease and patients are prone to feelings of stigmatization. In our cohort, we assessed how feelings of stigmatization may relate to patient quality of life (QOL), depression, and social anxiety. Participants completed the Dermatology Life Quality Index (DLQI) to assess QOL, Patient Health Questionnaire 9 (PHQ-9) to assess depression, the Brief Fear of Negative Evaluation (BFNE) to assess social anxiety, and an adapted version of the Feelings of Stigmatization (FoS) to assess stigmatization. The FoS also correlated with DLQI (R = 0.68), PHQ-9 (R = 0.42), and BFNE (R = 0.52). Participants with greater FoS were also more likely to have worse QOL (18.1), higher levels of depression (11.1), and higher social anxiety (30.1), as compared to those with less FoS (6.7, P < 0.001; 4.9, P < 0.001; 23.2, P < 0.001, respectively). HS is a chronic disease with no definitive treatment. Effective screening protocols, coupled with pharmacological and nonpharmacological interventions, may help patients with HS's psychosocial burden.

Satisfaction with Life and Coping Strategies among Patients with Hidradenitis Suppurativa: A Cross-Sectional Study

INTRODUCTION

Hidradenitis suppurativa (HS) is a chronic recurrent inflammatory dermatosis with vast psychosocial burden. The objective of this study is to thoroughly analyze satisfaction with life (SWL) and coping strategies of HS patients in relation to the clinical and psychosocial factors.

METHODS

114 HS patients (53.1% females; mean age 36.6 ± 13.1 years) were enrolled. Severity of the disease was measured using Hurley staging and International HS Score System (IHS4). Instruments utilized: Satisfaction with Life Scale (SWLS); Coping-Orientation to Problems-Experienced Inventory (Brief COPE); HS Quality of Life Scale (HiSQoL); Patient Health Questionnaire-9 (PHQ-9); Generalized Anxiety Disorder-7 (GAD-7); General Health Questionnaire (GHQ-28).

RESULTS

SWL was low in 31.6% of HS patients. No relation was found between SWL and Hurley staging and IHS4. SWL correlated with GHQ-28 (r = -0.579 p < 0.001), PHQ-9 (r = -0.603 p < 0.001), GAD-7 (r = -0.579 p < 0.001), and HiSQoL (r = -0.449 p < 0.001). Problem-focused coping strategies were most commonly used, followed by emotion-focused coping and avoiding coping strategies. Significant differences were found between the following coping strategies and SWL: self-distraction (p = 0.013), behavioral-disengagement (p = 0.001), denial (p = 0.003), venting (p = 0.019), and self-blame (p = 0.001).

CONCLUSIONS

HS patients present low SWL which correlates with psychosocial burden. Reducing anxiety-depression comorbidity and encouraging optimal coping strategies may be of great importance in holistic approach to HS patients.

Neutrophilic granulocyte-derived B-cell activating factor supports B cells in skin lesions in hidradenitis suppurativa

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic inflammatory disease characterized by painful inflamed nodules, abscesses, and pus-draining tunnels appearing in axillary, inguinal, and perianal skin areas. HS lesions contain various types of immigrated immune cells.

OBJECTIVE

This study aimed to characterize mediators that support lesional B/plasma cell persistence in HS.

METHODS

Skin samples from several cohorts of HS patients and control cohorts were assessed by mRNA sequencing, quantitative PCR on reverse-transcribed RNA, flow cytometry, and immunohistofluorescence. Blood plasma and cultured skin biopsy samples, keratinocytes, dermal fibroblasts, neutrophilic granulocytes (neutrophils), monocytes, and B cells were analyzed. Complex systems biology approaches were used to evaluate bulk and single-cell RNA sequencing data.

RESULTS

Proportions of B/plasma cells, neutrophils, CD8+ T cells, and M0 and M1 macrophages were elevated in HS lesions compared to skin of healthy and perilesional intertriginous areas. There was an association between B/plasma cells, neutrophils, and B-cell activating factor (BAFF, aka TNFSF13B). BAFF was abundant in HS lesions, particularly in nodules and abscesses. Among the cell types present in HS lesions, myeloid cells were the main BAFF producers. Mechanistically, granulocyte colony-stimulating factor in the presence of bacterial products was the major stimulus for neutrophils' BAFF secretion. Lesional upregulation of BAFF receptors was attributed to B cells (TNFRSF13C/BAFFR and TNFRSF13B/TACI) and plasma cells (TNFRSF17/BCMA). Characterization of the lesional BAFF pathway revealed molecules involved in migration/adhesion (eg, CXCR4, CD37, CD53, SELL), proliferation/survival (eg, BST2), activation (eg, KLF2, PRKCB), and reactive oxygen species production (eg, NCF1, CYBC1) of B/plasma cells.

CONCLUSION

Neutrophil-derived BAFF supports B/plasma cell persistence and function in HS lesions.

A Prospective Observational Study to Evaluate the Factors Affecting the Dermatology Life Quality Index in Patients With Hidradenitis Suppurativa

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic, relapsing inflammatory skin disease that significantly affects the quality of life of patients. Multiple factors affect the disease's course and severity. HS is a debilitating disease and often recalcitrant to treatment, resulting in a deterioration of quality of life; hence, there is a need to evaluate the factors affecting the quality of life in patients with HS.

OBJECTIVES

The objective of the study was to evaluate the various demographic and disease-related factors that affect the quality of life of patients with HS.

MATERIALS AND METHODS

This is a prospectively scored questionnaire-based observational study. Data from 30 patients with HS were analyzed for the association of disease-related factors like Hurley's staging, site, duration, past history, and comorbidities with the Dermatology Life Quality Index (DLQI).

RESULTS

A statistically significant relationship was found between DLQI and Hurley staging (p=0.000). The most common sites involved were the axilla and inguinal regions. Among the sites involved, the neck (p=0.002), abdomen (p=0.002), back (p=0.002), thighs (p=0.042), and gluteal (p=0.000) regions have a statistically significant association with DLQI. Prior histories of rheumatoid arthritis, scarring, surgery, lymphadenitis, and pilonidal sinus showed a statistically significant association with DLQI.

CONCLUSION

The disease severity significantly hampers the quality of life of patients with HS. The disease site and presence of other comorbidities also influence the outcome. Our study will help healthcare providers better understand and fulfill the needs of patients suffering from HS.

The impact of surgical interventions on the psychosocial well-being of patients with hidradenitis suppurativa

BACKGROUND AND OBJECTIVES

Hidradenitis suppurativa is a chronic inflammatory skin disease. Depending on disease severity, a combination of conservative and surgical treatments is necessary. This analysis aimed to determine the impact of surgical interventions on patient psychosocial well-being.

PATIENTS AND METHODS

This is a prospective, noninterventional, multicenter study. The medical history, medical examination, and patient-reported outcomes, including the Hospital Anxiety and Depression Scale, Dermatology Life Quality Index, and the Short Form-12 Health Survey, were collected from 481 patients with hidradenitis suppurativa.

RESULTS

Among all patients with hidradenitis suppurativa included in this study, 74.2% reported surgery before study inclusion, of whom 92.4% could identify surgery type and location. Although adjusted for confounding factors, such as disease severity and activity, the aforementioned patient reported outcomes, did not vary significantly between groups of patients with different techniques and number of prior surgical intervention. However, patients without any prior surgical intervention yielded significantly better scores.

CONCLUSIONS

In patients with hidradenitis suppurativa, previous surgery was associated with worse outcomes in anxiety, depression, and quality of life, showing the apparent need of psychological support. It remains unclear whether the morbidity of surgical procedures or a possible higher severity score in patients undergoing surgery is responsible.

Measuring Quality of Life in Hidradenitis Suppurativa: Development and Validation of a Disease-specific Patient-reported Outcome Measure for Practice and Research

Hidradenitis suppurativa is a chronic disease that disrupts patients' physical and psychological well-being. A disease-specific measure was developed and validated for assessing health-related quality of life in hidradenitis suppurativa. After qualitative item development, the quality of life in hidradenitis suppurativa instrument was tested in 101 patients, applying convergent measures and a usability questionnaire. Descriptive and validation-specific analyses were conducted. There was no ceiling, but moderate floor effects (scores between 0 and 3.13 on a scale of 0-4). Few missing values were observed (21 of 23 items < 5%). Internal consistency was satisfying: 2 subscales with 6 and 16 items were identified (Cronbach's alpha=0.95 and 0.88). The quality of life in hidradenitis suppurativa instrument correlated significantly with all convergent criteria (including change in convergent patient-reported outcomes; p < 0.05) except for Hurley stage (p = 0.490). In conclusion, the quality of life in hidradenitis suppurativa questionnaire is an internally consistent, valid, responsive, and usable instrument to assess quality of life in patients with hidradenitis suppurativa.

Pain experiences among those living with hidradenitis suppurativa: a qualitative study

BACKGROUND

Pain is rated by patients with hidradenitis suppurativa (HS) as the disease's most impactful symptom. HS therapies are often insufficient to control inflammatory disease activity and pain. A better understanding of patient experiences with pain may improve patient-provider relationships and help identify strategies for addressing HS pain.

OBJECTIVES

This qualitative study sought to characterize lived pain experiences of those with HS.

METHODS

English-speaking patients ≥ 18 years old with a dermatologist-confirmed diagnosis of HS and an average numerical rating scale pain score of ≥ 1 over the preceding week were recruited from a single academic medical centre in Atlanta, Georgia, USA. Semistructured interviews were conducted from November 2019 to March 2020 to explore participants' HS pain experiences and the subsequent impact on their lives. Thematic saturation was reached after interviewing 21 participants. Interviews were audio recorded, transcribed, and analysed using thematic analysis.

RESULTS

Among 21 study participants, the median 7-day average pain score was 6 (interquartile range 3-7; scale ranges from 0 to 10, with 10 being most pain). Participants' descriptions of pain were consistent with nociceptive pain, neuropathic pain and itch. Pain impacted multiple life domains, including physical limitations (decreased mobility and impaired sleep), decreased psychological wellbeing (irritability, depression, loss of control, and difficulty communicating pain experiences) and impaired social relationships (social isolation, intimacy problems and difficulty fulfilling social responsibilities). Although participants reported chronic discomfort, acutely painful and unpredictable HS disease flares caused more distress and quality-of-life (QoL) burden. Participants frequently treated their pain without input from the medical team, sometimes with unsafe medication doses or combinations. Factors contributing to self-management of pain included difficulty accessing timely outpatient care during disease flares and fear of stigma from healthcare providers.

CONCLUSIONS

When present, HS-related pain may impact not only physical wellbeing but also mental health and relationships. In addition to therapies that target the inflammatory disease burden, treating the symptom of pain may improve patients' QoL and wellbeing. Because patients with HS have difficulty explaining their pain, proactively asking them about pain may identify unmet needs, facilitate better pain control and improve QoL. Further, the influence of HS-related pain on numerous aspects of QoL suggests the need for multidisciplinary, patient-centred approaches to HS pain management.

Non-surgical treatment of hidradenitis suppurativa: the role of cryotherapy

Background

Hidradenitis suppurativa is a chronic and recurrent inflammatory disease with a great impact on a patient's quality of life, due to the painful involvement of very sensitive areas, such as the groin, mammary area, and genitals, with malodourous discharge. Multiple treatment options are available; however, no single treatment is effective for all patients, and usually, a combination of medical therapy with various surgical and physical procedures is provided. Cryotherapy is not a routine technique to treat HS, although usually available in the majority of medical clinics, and is cheaper than laser and surgical treatments. The aim of this study was to evaluate the effectiveness of cryotherapy on persistent HS nodules, to reduce the burden of local disease.

Materials and methods

Retrospective observational study in all patients treated with liquid nitrogen cryotherapy for persistent nodules of hidradenitis suppurativa in the last 2 years, with at least 6 months of follow-up after the procedure. Disease severity was assessed with Hurley staging and sonographic staging according to SOS-HS (18 MHz probe, Esaote-MyLab™). The results were scored with a 0-3 points scale, as complete remission (3), partial response (2 to 1), or no response (0), after one session of treatment. Local cleansing and antiseptic treatment after the procedure was the same as previously performed in each patient, not to influence recovery.

Results

In total, 23 patients were included, with a total of 71 persistent nodules treated with a single cryotherapy session. The treatment has been effective in 63 out of 71 nodules treated (88.7%), and the patients attested that they recommend the treatment, the discomfort during recovery was minimal, and the management was not different from daily routine. Persistence was considered as having a failure rate (11.3% overall) and occurred in 7.5% of the nodules of the axillary region, 18.2% on the groin, and 11.2% for nodules of the gluteal region.

Conclusion

Cryotherapy is a simple and effective procedure for the treatment of persistent nodules of HS not responding to medical therapy, and it is a valid alternative to local surgery or laser ablation.

Sexual Dysfunction and Quality of Life in Patients with Hidradenitis Suppurativa and Their Partners

Hidradenitis suppurativa (HS) is a chronic skin disease that profoundly affects patients' quality of life (QoL) and sexuality. Few data are available on the impact of HS on patients' partners. We aimed to explore the QoL and sexual function of patients' partners and the factors associated with their impairment and to compare the QoL and sexual function of single patients and those in a stable relationship. We conducted a cross-sectional study at Hospital Universitario Virgen de las Nieves (Granada, Spain) and at the Wroclaw Medical University (Wroclaw, Poland). Patients over the age of 16 years attending their scheduled follow-up and their partners, if any, were included. The Dermatology Life Quality Index (DLQI) and the Family Dermatology Life Quality Index (FDLQI) were used to estimate the QoL of patients and partners, respectively. The FSFI-6 was used to determine sexual dysfunction in women and the IIEF-5 for erectile dysfunction in men. Thirty-four single patients and twenty-eight patients in a stable relationship and their partners were included. Patients had a very large impact (DLQI 12.5 ± 7.5) and their partners a moderate impact (FDLQI 10.3 ± 7.1) in their QoL due to HS. Women with HS had a high prevalence of sexual dysfunction (13/32, 40.6%) and men of erectile dysfunction (19/30, 63.3%). Male partners also had a high prevalence of erectile dysfunction (10/17, 58.8%), while only one female partner had sexual dysfunction (1/11, 9.1%). Factors related to disease severity, intensity of symptoms and body mass index were associated with poorer QoL in partners and time of disease evolution with greater erectile dysfunction in male partners. In conclusion, HS not only profoundly affects the QoL and sexuality of patients but also of their partners. Several risk factors have been identified, which should be taken into account in the holistic approach of the disease.

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.

Facial acne causes stigmatization among adolescents: A cross-sectional study

BACKGROUND

Stigmatization is defined as a discrediting mark which sets the person from others and hindering interpersonal relationships. Literature data on stigma in acne subjects are scarce.

AIMS

This study was undertaken to assess feelings of stigmatization in adolescents with facial acne.

MATERIAL/METHODS

The study was performed on 730 high-school students aged 15 to 19 years with the mean age of 17.05 ± 1.18 years. Self-reported acne was found in 74.9% of subjects. The severity of acne was self-assessed with the standardized color images based on Investigators Global Assessment (IGA). Stigmatization was studied with 6-Item Stigmatization Scale (6-ISS) and Perceived Stigmatization Questionnaire (PSQ). Additionally, quality of life (QoL) was evaluated with Dermatology Life Quality Index (DLQI).

RESULTS

58% of adolescents with acne presented with feelings of stigmatization. Within the acne population, stigmatization was significantly more common in females than in males (p < 0.001). The mean level of stigmatization according to 6-ISS was significantly higher in acne sufferers than in those free from acne (1.68 ± 2.42 points and 0.55 ± 1.50 points, respectively; p < 0.001). Feelings of stigmatization were significantly more pronounced by females than males (p < 0.001). Staring at the skin and the fact that others are not attracted to person due to skin lesions were main problems raised by the study participants with acne. 6-ISS scores correlated with acne severity (r = 0.278; p < 0.001) and both 6-ISS and PSQ scores with QoL impairment (r = 0.530; p < 0.001 and r = 0.341; p < 0.001, respectively).

CONCLUSIONS

Facial acne is a highly stigmatized skin disease and requires a holistic therapeutic approach.

Impact of hidradenitis suppurativa-specific wound dressing system on patient quality of life and dressing-related pain: pilot study

Objective:

It is theorised that adhesive-free wound care developed specifically for patients with hidradenitis suppurativa (HS) can improve their quality of life (QoL). Our study aimed to investigate the impact of a novel wound care device on Dermatology Life Quality Index (DLQI) scores, and other factors related to experienced pain, time spent changing dressings, comfort, ease of use and body image.

Method:

A 21-day, single-arm, unblinded, pilot trial was conducted to assess ease of use and the impact of effective wound care on various aspects of wound management in patients with HS. Participants were provided two trial garments and trial dressings as required, to use over a 21-day period in the home setting. A seven-item questionnaire and the DLQI questionnaire was completed on days 0, 7, 14 and 21.

Results:

All 15 participants were female, aged >18 years old and with a diagnosis of HS. Mean DLQI score at baseline (day 0) was 19.3, which was reduced to 4.53 on day 21, a significant improvement in 100% of participants (p<0.001). High levels of dressing-related pain, assessed using an 11-point Visual Analogue Scale, reduced from 5.53 at baseline to 0.8 on day 21. Other significant improvements in terms of patient comfort, time spent on changing dressings, body confidence and the dressing's ability to retain exudate were also noted.

Conclusion:

The results illustrated the improvement made to study participants' day-to-day activities and QoL when effective HS-specific wound care products were provided. Wound care is an essential component in the treatment journey of patients.

Sex-disaggregated population analysis in patients with hidradenitis suppurativa

BACKGROUND

Hidradenitis suppurativa (HS) is a common chronic inflammatory skin disease, which affects both sexes.

OBJECTIVES

Identification of sex-specific risk factors, comorbidity, clinical manifestations, and treatments in HS patients.

METHODS

A non-interventional, cross-sectional, mono-centric study with 500 HS patients. All patients were examined by dermatologists. Prospectively collected demographic, anamnestic, clinical data, and blood parameters were evaluated.

RESULTS

There were no significant differences in age at HS onset and in disease duration between female and male patients. Furthermore, no differences regarding the family history for HS were found between sexes. Regarding further risk factors for HS, central obesity was more frequent in women while extensive cigarette smoking and acne vulgaris were more commonly found among male patients. Regarding comorbidity, lower HDL-levels were significantly more frequent in men. Female patients were found to suffer significantly more often from back pain, especially in the neck/shoulder region and lower back. Analyzing the clinical manifestation of HS, the groin was more frequently involved in women and the axillae in men. Women showed a higher number of skin sites with inflammatory nodules, whereas fistulas were observed more frequently in men. Nevertheless, there was no difference in HS treatment applied to female vs. male patients.

LIMITATIONS

Data were obtained from a mono-centric study.

CONCLUSION

Significant differences in HS risk factors, comorbidity, and clinical manifestation exist between female and male patients. Thus, sex-specific differences should be taken into account in the prevention as well as medical and surgical treatment of HS patients.

Impact of Hidradenitis Suppurativa Surgical Treatment on Health-Related Life Quality

(1) Background: Hidradenitis suppurativa is a disease that affects the intimacy of patients. This disease reduces the quality of life and functioning of patients in everyday life. The surgical treatment of HS is one of the treatments for HS that can improve the quality of life. (2) Methods: The main goal of this study was to assess quality of life before the surgical treatment and after the surgical treatment of HS at Center for Burn Treatment in Siemianowice Śląskie, Poland, using the EQ-5D-5L survey before the operation and at follow-up (6 months after). (3) Results: The average quality of life measured with the EQ-5D-5L survey before therapy was 39.3 ± 20.1 (min., 0; max., 60; most frequent value, 50), whereas after surgical treatment, the mean quality of life was 89.5 ± 12.5 (min., 50; max., 100; most frequent value, 100). The average increase in the quality of life was 50.2 ± 19.5 (min., 30; max., 100; most frequent value, 30), and it was statistically significant (p < 0.001).

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.

Unmet Medical Needs in Chronic, Non-communicable Inflammatory Skin Diseases

An estimated 20-25% of the population is affected by chronic, non-communicable inflammatory skin diseases. Chronic skin inflammation has many causes. Among the most frequent chronic inflammatory skin diseases are atopic dermatitis, psoriasis, urticaria, lichen planus, and hidradenitis suppurativa, driven by a complex interplay of genetics and environmental factors. Autoimmunity is another important cause of chronic skin inflammation. The autoimmune response may be mainly T cell driven, such as in alopecia areata or vitiligo, or B cell driven in chronic spontaneous urticaria, pemphigus and pemphigoid diseases. Rare causes of chronic skin inflammation are autoinflammatory diseases, or rheumatic diseases, such as cutaneous lupus erythematosus or dermatomyositis. Whilst we have seen a significant improvement in diagnosis and treatment, several challenges remain. Especially for rarer causes of chronic skin inflammation, early diagnosis is often missed because of low awareness and lack of diagnostics. Systemic immunosuppression is the treatment of choice for almost all of these diseases. Adverse events due to immunosuppression, insufficient therapeutic responses and relapses remain a challenge. For atopic dermatitis and psoriasis, a broad spectrum of innovative treatments has been developed. However, treatment responses cannot be predicted so far. Hence, development of (bio)markers allowing selection of specific medications for individual patients is needed. Given the encouraging developments during the past years, we envision that many of these challenges in the diagnosis and treatment of chronic inflammatory skin diseases will be thoroughly addressed in the future.

Which hidradenitis suppurativa comorbidities should I take into account?

Hidradenitis suppurativa (HS) is a chronic, recurrent skin inflammatory disease associated with a variety of comorbidities, like metabolic syndrome, reduced quality of life, sexual dysfunction, working disability, inflammatory bowel disease, axial spondyloarthritis, depression and anxiety. Like psoriasis, HS patients have been found to have higher risk of cardiovascular death and suicide risk. Evidence suggests that for such a chronic, multi-comorbid disease, the use of validated outcomes to assess severity and effect of treatment, along with the use of clinically important patient reported outcomes, is essential. Clinicians should be informed about these comorbidities so that appropriate screening is implemented. The potential of available treatments to negatively and positively affect these comorbidities should also be taken into account when designing treatment strategies. This article aims to provide an outline of important HS comorbidities with emphasis on possible implications for daily clinical practice.

Treatment of Hidradenitis Suppurativa Evaluation Study (THESEUS): protocol for a prospective cohort study

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic, painful, inflammatory skin disease with estimates of prevalence in the European population of 1%-2%. Despite being a relatively common condition, the evidence base for management of HS is limited. European and North American management guidelines rely on consensus for many aspects of treatment and within the UK variations in management of HS have been identified. The HS James Lind Alliance Priority Setting Partnership (PSP) published a top 10 list of future HS research priorities including both medical and surgical interventions. The aims of the THESEUS study are to inform the design of future HS randomised controlled trials (RCTs) and to understand how HS treatments are currently used. THESEUS incorporates several HS PSP research priorities, including investigation of oral and surgical treatments. Core outcome domains have been established by the HIdradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC) and THESEUS is designed to validate instruments to measure the domains.

METHODS AND ANALYSIS

The THESEUS study is a prospective observational cohort study. Participants, adults with active HS of any severity, will be asked to select one of five HS treatment options that is appropriate for their HS care. Participants will be allocated to their chosen treatment intervention and followed for a period of up to 12 months. Outcomes will be assessed at 3-monthly intervals using HISTORIC core outcome instruments. Video recordings of the surgical and laser operations will provide informational and training videos for future trials. Nested mixed-methods studies will characterise the interventions in clinical practice, understand facilitators and barriers to recruitment into future HS RCTs and examine patients' and clinicians' perspectives on HS treatment choices.

TRIAL REGISTRATION NUMBER

Real-World Moderate-to-Severe Hidradenitis Suppurativa: Decrease in Disease Burden With Adalimumab

BACKGROUND

Real-world knowledge of the burden of hidradenitis suppurativa (HS) on patients remains limited.

OBJECTIVES

To measure the impact of adalimumab on moderate-to-severe HS patients' health-related quality of life (HRQoL) and work productivity.

METHODS

In 23 Canadian centres, 138 adults with moderate-to-severe HS requiring a change in ongoing therapy were treated with adalimumab for up to 52 weeks as per the physician's practice. Patient-reported outcome measures (PROMs) were obtained at baseline, weeks 24 and 52 to measure overall HRQoL, HS severity, levels of anxiety and depression, impact and symptoms of HS, work productivity and activity impairment. A post-hoc analysis further explored the PROMs by abscess and inflammatory nodule (AN) count at baseline (≤5, low; 6-10, medium; ≥11, high).

RESULTS

From baseline to weeks 24 and 52, all PRO overall scores improved significantly (P ≤ .0023). The number of patients reporting "good disease control" and "complete disease control" increased from 9.7% to 66.4% over 52 weeks. The score in Health Utility Index Mark 3 (HUI3) pain attribute meaningfully decreased over 52 weeks (mean difference ≥.05). The HS symptoms skin "tenderness" and "itchiness" improved the most. Work productivity loss and activity impairment improved by approximately 20% over 52 weeks. Disease burden improved more in 24 week responders with low and medium AN counts at baseline than in those with high AN count or in 24 week nonresponders.

CONCLUSION

At week 24 and maintained at week 52 in a real-world setting, adalimumab meaningfully improved HRQoL, work productivity, and activity impairment in moderate-to-severe HS patients.

Self-Reported Hidradenitis Suppurativa Severity: Is It Useful for Clinical Practice?

Introduction

Hidradenitis suppurativa (HS) is considered to be the most burdensome dermatosis, with a well-documented negative influence on quality of life (QoL). The patient’s perception of the disorder, assessed as the self-reported severity, has been used in other dermatoses but not in HS. The aim of this study was to evaluate the usefulness of self-reported HS severity in clinical practice.

Methods

The study was performed on a group of 130 Spanish HS patients. HS severity was assessed for all the subjects. Hurley staging and patient self-reported severity were used. Moreover, QoL impairment was evaluated using the Dermatology Life Quality Index (DLQI) and the Hidradenitis Suppurativa Quality of Life 24 (HSQoL-24) questionnaire.

Results

The severity of HS according to the Hurley staging was most commonly assessed as Hurley II (47.7%), indicating moderate disease, followed by severe disease (Hurley III, 26.9%) and mild disease (Hurley I, 25.4%). According to the patient self-reported HS severity, most of the patients reported having mild disease (76 patients, 58.5%), followed by moderate disease (31 patients, 23.8%). Only 23 patients (17.7%) assessed their disease as severe. Moreover, men reported mild disease significantly more frequently than women (70.9% and 49.3%, respectively; p = 0.014).

The self-reported HS severity correlated positively with the effect of the disease on patient QoL assessed with DLQI (r = 0.288, p < 0.001). Likewise, a strong positive correlation was found between self-reported HS severity and QoL impairment assessed with HSQoL-24 (r = 0.404, p = 0.001). No statistically significant correlation between Hurley severity stage and DLQI or HSQoL-24 was found. Moreover, there were significant differences in both DLQI and HSQoL-24 total score between different self-reported HS severities. This was not seen for any of the QoL instruments or for Hurley severity staging.

Conclusion

The results show that self-assessment severity may reflect patients’ subjective feelings more adequately than popular objective instruments, and there should be a place for its use in daily clinical practice.

IL-17RA blockade by brodalumab decreases inflammatory pathways in hidradenitis suppurativa skin and serum

BACKGROUND

Hidradenitis suppurativa (HS) is an inflammatory skin disease with dysregulation of the IL-17 axis. Recently we reported clinical benefit of brodalumab, a human anti-IL-17 receptor A (IL-17RA) monoclonal antibody, in moderate-to-severe HS.

OBJECTIVES

To characterize the molecular response to brodalumab in HS skin and serum, and to identify biomarkers of treatment response.

METHODS

Ten participants that received 210 mg/1.5mL brodalumab subcutaneously at week 0, 1, 2, 4 and every 2 weeks after were included in this molecular profiling study (NCT03960268). RNA-sequencing and immunohistochemistry of nonlesional, perilesional and lesional HS skin biopsies, and Olink high throughput proteomics of serum at baseline, week 4 and week 12 were assessed.

RESULTS

At week 12, brodalumab led to a decrease of overall inflammation, and improvement of psoriasis-, keratinocyte- and neutrophil-related pathways. Despite perilesional and lesional skin having no differentially expressed genes at baseline, treatment response was best assessed in perilesional skin. In serum, brodalumab treatment decreased pathways involved in neutrophil inflammation. Patients with higher baseline expression of neutrophil-associated Lipocalin-2 (LCN2) in the skin and IL-17A in the serum demonstrated greater decreases of HS-related inflammatory cytokines as measured in skin biopsies at week 12.

CONCLUSIONS

IL-17RA inhibition by brodalumab impacts several pathogenic inflammatory axes in HS. Perilesional skin provides a valid and robust assessment of treatment response. Expression of LCN2 in skin and IL-17A in serum may be used as biomarkers to stratify patients that may have a superior molecular response to brodalumab =.

Internalized skin bias: Validation study to explore the impact of the internalization of social stigma on those with hidradenitis suppurativa

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic auto-inflammatory disease that is highly associated with adverse psychopathology and impaired body image. Previous studies show that patients with HS are also impacted by social stigma associated with their skin disease. Over time, these experiences can influence the way in which patients feel about themselves, leading to internalized skin bias (ISB).

OBJECTIVES

To evaluate the validity and reliability of the Internalized Skin Bias Questionnaire (ISBQ) in an HS population, and to determine the association of this instrument with markers of HS severity.

METHODS

A cross-sectional survey with 72-hour retest was sent to adult patients with HS from March to November 2021. Reliability for the ISBQ was evaluated using Cronbach's alpha and the Concordance Correlation Coefficient (CCC). Construct validity was evaluated using Pearson Correlation Coefficients with similar measures.

RESULTS

Internal consistency for the ISBQ instrument was 0.89 with a CCC of 0.88. The ISBQ had moderate correlation (r = 0.63) with the experienced skin stigma questionnaire as well as the BDI-II (r = 0.66) and the psychosocial subscale of the HiSQOL (r = 0.65). ISBQ scores differed significantly across different stages of disease severity (p=0.04). There was no significant difference between those with different durations of disease (p=0.47).

CONCLUSIONS

This study shows that the ISBQ is a valid and reliable instrument that can be used to assess the psychosocial construct of ISB especially in a population of HS patients. Further, ISB places a prevalent negative impact on the psychopathology of patients with HS.

Modified Posterior Arm Flap for Axillary Hidradenitis Suppurativa

INTRODUCTION

Hidradenitis suppurativa (HS) is a chronic, inflammatory condition of the apocrine sweat glands present in 1% to 4% of the adult population, with twice greater prevalence in females. Surgical excision is the criterion-standard treatment for advanced, grade III disease, characterized by extensive and recurrent abscesses and interconnected sinus tracts. Numerous reconstructive methods have been used to cover the resulting defects, including secondary intention healing, use of skin grafts, and a wide range of locoregional flaps.

METHODS

The modified posterior arm flap has been developed for reconstruction of axillary defects after radical excision of HS. Based on perforating vessels from the axillary artery first identified by Masquelet, a brachioplasty-like incision is used to keep the donor site closure relatively hidden on the posteromedial aspect of the inner arm.

RESULTS

Eight modified posterior arm flaps have been undertaken in 6 patients, all women (mean age, 35 years; range, 22-51 years) from 2014 to 2019. All patients had complete resolution of their HS symptoms with no incidences of recurrence at mean follow-up of 15 months. All reported satisfaction with the aesthetic and functional outcomes of the procedure.

DISCUSSION

We present a novel modification of the posterior arm flap for the treatment of advanced axillary HS with good functional and aesthetic outcomes and no incidences of recurrence.

Quality of Life of Patients With Hidradenitis Suppurativa in Jeddah, Saudi Arabia

Background 

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that affects the apocrine gland-bearing areas of the body. It initially presents as painful nodules that eventually develop into abscesses, draining sinuses, and scarring. These manifestations have physical and psychological impacts, which lead to poor quality of life. This study examined the association between quality of life and disease severity, as well as identified the areas of the body most affected by HS among patients in Saudi Arabia.

Methods

This cross-sectional study examined patients with HS who were seen at two dermatology outpatient clinics between December 2018 and March 2019. The patients completed a self-administered standardized questionnaire on the Dermatology Life Quality Index (DLQI).

Results

The average DLQI score was 15.39 ± 8.37. The majority of patients were classified as stage 3, which indicated that HS has a very large effect on quality of life. The right and left axillae were the most commonly affected areas of the body, with 80.6% of patients noting involvement. While the mean DLQI score was higher in males compared to females, there was no significant difference between the two groups (16.44 ± 9.01 vs. 13.08 ± 6.65; P = 0.248).

Conclusion

HS caused significant impairment in the quality of life of patients with HS in Saudi Arabia. The mean DLQI score in our study was higher than the score previously reported in the literature. Further studies may identify opportunities to provide additional awareness, care, and support for patients with HS in Saudi Arabia.

Improvement in Quality of Life and Pain in Patients With Hidradenitis Suppurativa After Wide Local Excision: A Prospective Study

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects patients' quality of life (QoL).

OBJECTIVE

To investigate changes in QoL in patients with HS after wide local excision (WLE) and to examine the level of pain, rate of postoperative complications, recurrences, and the time to complete wound closure.

METHODS

Fifty-five patients were enrolled in this prospective study. All patients underwent WLE of HS, followed by secondary wound healing. Dermatologic Life Quality Questionnaire, pain, and wound size were measured 1 day, 3 weeks, 3 months, and 6 months after surgery.

RESULTS

Dermatologic Life Quality Questionnaire and pain scores (mean ± SD) improved significantly (both p < .001) from 14.5 ± 7.3 and 3.7 ± 2.8 at baseline to 5.8 ± 6.9 and 0.8 ± 1.7, 6 months postoperatively, respectively. Wounds were closed completely by secondary intention after 4.4 ± 2.8 months. Sixteen patients (29.1%) experienced postoperative complications, local recurrences in the treated sites were observed in 11 patients (20%), and new lesions in untreated sites were observed in 5 cases (9.1%).

CONCLUSION

Wide local excision significantly improves patients' QoL and pain, and, given its low rate of recurrence and complications, should be considered as a first-line therapy, especially in patients with higher Hurley stages.

The Use of HSQoL-24 in an Assessment of Quality-of-Life Impairment among Hidradenitis Suppurativa Patients: First Look at Real-Life Data

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder with well-documented effects on patients' quality of life (QoL). The aim of this study was to evaluate the QoL of patients with HS via the use of a newly developed questionnaire: Hidradenitis Suppurativa Quality of Life-24 (HSQoL-24). This study was performed on a population of 342 HS patients. Their QoL was assessed via the HSQoL-24 questionnaire. The perceived impairment of QoL due to HS in the studied group was considered to be serious (mean HSQoL-24 score: 58.3 ± 21.0 points). Women tended to experience a significantly higher impact from the disease than men (61.6 ± 19.2 points vs. 51.1 ± 23.1 points, p < 0.001). The HS severity had an effect on the perceived QoL, with statistically significant differences being evident between the self-assessed HS severity groups. The level of QoL impairment correlated positively with the number of affected body areas (r = 0.285, p < 0.001) and the duration of the disease (r = 0.173, p = 0.001), while the patients' age at disease onset correlated negatively with the HSQoL-24 global score (r = -0.182, p = 0.001). Patients living in their family house scored higher than other groups. The least affected were patients who lived alone. The study shows that the HSQoL-24 questionnaire is a reliable, HS-specific tool for measuring the QoL among patients with HS in real-life clinical settings.

Patients With Hidradenitis Suppurativa Negatively Perceive Both Medical and Euphemistic Appellations of Their Disease: A Study From Turkey

Background

The use of medical terms and folk names (euphemisms) affect a patient's understanding of diseases and perceptions of severity.

Objectives

We determine the psychological effects on patients with hidradenitis suppurativa of medical and folk names of their disease.

Methods

This was a cross-sectional and exploratory study conducted at a tertiary referral university hospital in Turkey. A questionnaire on the medical and folk names of hidradenitis suppurativa was administered to 31 males and 25 females.

Results

The patients expressed that they found the medical term hidradenitis suppurativa to be incomprehensible because it is a foreign term. When hearing it for the first time, it evoked negative responses such as confusion and worry about their health. Half of the patients preferred their doctors to use a more understandable and pronounceable name. More than 80% of patients expressed feeling depressed and stigmatized by the folk name of their disease. They preferred the terms boils, abscesses, or hidradenitis when referring to their disease.

Conclusion

Both medical and folk names for hidradenitis suppurativa have negative effects on patients, and most patients feel stigmatized by either term.

Indirect Self-Destructiveness in Hidradenitis Suppurativa Patients

Hidradenitis suppurativa (HS) is a chronic, debilitating skin condition that negatively affects patients’ quality of life. Indirect self-destructiveness refers to activities extended over time, such as addictions, risky behaviors, neglects, resignation, helplessness. These can be an additional factor impeding the achievement of positive clinical effects in the treatment of HS patients, therefore the objective of the study was to assess the indirect self-destructive behaviors in patients suffering from HS. The study group involved 100 adult HS patients with 59 males and 41 females. Indirect self-destructiveness was investigated with the Polish version of the Kelley’s Indirect Self-Destructiveness Scale (CS-DS). The study revealed that the average total score of indirect self-destructiveness in HS population was 130.16 ± 21.3 (median 128 points). The CS-DS scores were significantly higher in smoking patents (p = 0.006). The most expressed class of indirect self-destructiveness was A5 (Helplessness and Passivity). The indicated results pointed out a strong domination of passive forms of indirect self-destructiveness over its active forms. Due to related low self-esteem, social isolation and exclusion, HS patients are more prone to behave in a self-destructive manner, which may lead to poor health maintenance in a form of leaving appointments and non-adherence.

LAight® Therapy Significantly Enhances Treatment Efficacy of 16 Weeks of Topical Clindamycin Solution in Hurley I and II Hidradenitis Suppurativa: Results from Period A of RELIEVE, a Multicenter Randomized, Controlled Trial

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic, inflammatory, burdensome skin disease where medical first-line treatment is still limited to long-term, topical and/or systemic antibiotics. The RELIEVE study aimed at evaluating the efficacy of LAight® therapy - a combination of intense pulsed light and radiofrequency - as an adjunct treatment to first-line therapies in Hurley stage I and II HS.

METHODS

The RELIEVE study was performed as a two-period multicenter randomized controlled trial with blinded assessment. For period A from week 0 to week 16, the 88 participating subjects were randomized into either an intervention group (IG) or a control group (CG). The IG received topical clindamycin 1% solution combined with 8 additional bi-weekly treatments with LAight® therapy. The CG was treated with topical clindamycin 1% solution only. After 16 weeks, patients entered open-label period B and both groups were treated exclusively with LAight® therapy for an additional 16 weeks (8 sessions). The primary efficacy endpoint was the change in International Hidradenitis Suppurativa Score System (∆IHS4) at week 16 to baseline. Secondary endpoints were DLQI, HiSCR, Pain-NRS, and HADS.

RESULTS

In total, from the 88 patients enrolled in RELIEVE, 81 patients were included in the endpoint analysis after period A. After 16 weeks of treatment, the ∆IHS4 of the group treated with the combination of LAight® therapy and topical clindamycin 1% solution was -7.2 ± 6.7 (-60.0%), which was significantly higher in magnitude than the ∆IHS4 in the group treated with clindamycin 1% solution alone (-1.8 ± 5.6, -17.8%, p < 0.001). Secondary endpoints, including other clinical scores as well as patient-reported outcomes, confirmed that the efficacy of the combined treatment was superior to monotherapy.

CONCLUSION

The results of the primary endpoint analysis of period A of the RELIEVE study show that the combined therapy with LAight® and topical clindamycin 1% solution, resulted in a significantly higher decrease in disease severity and an improvement of quality of life in comparison to topical clindamycin 1% solution monotherapy. Treatment was well tolerated, and side effects were all mild and transitory. These data speak for the implementation of the combined treatment as a first-line therapy in Hurley stage I and II HS. LAight® therapy as long-term monotherapy (results from period B), will be analyzed in a consecutive paper.

Hidradenitis Suppurativa in a Large Cohort of Italian Patients: Evaluation of the Burden of Disease

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent, debilitating skin disease of the hair follicle that usually occurs after puberty with painful, deep-seated, inflamed nodules and sinus tracts in the apocrine gland-bearing areas of the body, most commonly the axillae and inguinal and anogenital regions, with a relevant impact on patients' quality of life (QoL).

OBJECTIVE

To evaluate how the burden of HS disease impacts on patient well-being and working activities in a large Italian population over a period of 9 months.

METHODS

A multicenter, prospective, epidemiologic cohort study was conducted in adult Italian patients with HS. HS severity was assessed through Hurley stage and HS Physician's Global Assessment (HS-PGA), clinical improvement by HS Clinical Response (HiSCR) and partial response, and disease burden through QoL questionnaires (HIDRAdisk, Skindex-16, Dermatology Life Quality Index [DLQI]), and Work Productivity and Activity Impairment - General Health (WPAI:GH).

RESULTS

A total of 308 patients (56.2% women; mean age 35.2 ± 12.9 years) were enrolled in 27 dermatologic clinics. Men were older (37.4 years vs. 33.5), more smoking addicted (74.1% vs. 60.1%), and alcohol consumer (34.1% vs. 13.9%), while more women were obese (34.10% vs. 22.22%). At baseline, most patients had a Hurley severity stage of 2 (43.9%), a moderate HS-PGA score (57.1%), and poor QoL (HIDRAdisk: 65.7 ± 23.3, Skindex-16: 60.3 ± 26.9, and DLQI: 10.8 ± 8.1). Patients with more severe disease showed worse QoL. Mean values for the variables related to HS severity decreased during the study period. The achievement of HiSCR and partial response increased during the study.

CONCLUSION

This study offers insight into the disease burden of HS in an Italian population. Our results underline the impact of QoL evaluation, also with the use of the HIDRAdisk, in clinical routine as a support to validated severity clinical and instrumental indexes for a "360-degree" assessment of HS patient's burden of disease.

The influence of superficial dermatophytoses epidemic in India on patients' quality of life

Introduction

Superficial dermatophytoses constitute a common and growing problem in India. However, the associated impact on the affected individuals’ quality of life (QoL) has rarely been investigated.

Aim

To assess the quality of life of patients with different dermatophytoses.

Material and methods

Among 100 consecutive Indian patients with dermatophytosis, 76% agreed to participate. The diagnosis was established upon the typical clinical manifestation and direct microscopic mycological examination (10% KOH). Dermatology Life Quality Index (DLQI) was utilized to assess QoL impairment. Participants evaluated the presence and intensity of itch during the last 3 days using Numeral Rating Scale (NRS).

Results

A combination of tinea corporis and tinea cruris was diagnosed most commonly (52.6%), followed by tinea cruris alone (21%) and tinea corporis alone (13.2%). The mean duration of the disease was assessed as 6.3 ±18.0 months. The mean DLQI score was 8.2 ±5.1 points. A very large and extremely large effect on the DLQI was reported by 26.3% of patients, moderate by 40.8%, whereas small by 29%, with females being more heavily affected than males (9.3 ±5.2 and 7.1 ±4.7 points, respectively) (p = 0.038). Patients with a combination of tinea corporis, tinea cruris and tinea faciei demonstrated the lowest QoL (11.0 ±4.5 points). Additionally, a significant correlation between impairment of QoL and itch intensity (mean NRS score: 6.8 ±1.8 points) (r = 0.37; p < 0.002) was documented. Moreover, there was a trend towards lower QoL in patients who have been previously treated with topical agents containing corticosteroids.

Conclusions

Superficial dermatophytoses are associated with a moderate impact on QoL of the affected subjects.

Alterations in mental health and quality of life in patients with skin disorders: a narrative review

The presence of lesions in visible areas of skin may cause emotional troubles in patients, including low self-worth, embarrassment, sorrow, and social isolation. Those alterations may predispose to psychiatric disorders such as anxiety, depression, and even suicidal ideation, severely affecting patients' health state and quality of life (QoL). In this article, we focus on dermatologic patients that present with secondary mental health alterations. Thus, we offer a detailed description of mental disorders observed in patients with acne vulgaris, atopic dermatitis, psoriasis, ichthyosis, vitiligo, and hidradenitis suppurativa. Moreover, we point out the relationship between the severity of the cutaneous symptoms with mental illnesses and QoL decline. Our objective was to highlight the importance of mental health care for patients with skin diseases. The impact of skin alterations on the mental health of dermatological patients should be a central concern. Likewise, the timely identification and treatment of mental disorders are essential for the comprehensive management of these skin diseases.

Economic analysis of the costs associated with Hidradenitis suppurativa at a German University Hospital

Background and objectives

Hidradenitis suppurativa (HS) significantly affects the patient`s quality of life and leads to multiple medical consultations. Aim of this study was to assess the utilization of medical care of HS patients.

Patients and methods

All patients presenting in 2017 for an outpatient, day patient and / or inpatient treatment with leading claim type HS at the Department of Dermatology, University Hospital Würzburg, were included. Primary outcome was the economic burden of HS patients, measured by resource utilization in €.

Results

The largest share of the direct medical costs for HS were the inpatient costs with a leading surgical diagnosis-related group (DRG). Antiseptics were the predominant topical prescription. While doxycycline was the most frequently prescribed systemic therapy, adalimumab was the main cost driver. The difference between in-patient (€ 110.25) and outpatient (€ 26.34) direct non-medical costs was statistically significant (p < 0.001). With regards to indirect medical costs, a statistically significantly higher loss of gross value added (inpatient mean € 1,827.00; outpatient mean € 203.00) and loss of production (inpatient mean € 1,026.00; outpatient mean € 228.00) could be noted (p < 0.001), respectively.

Conclusions

The present study on disease-specific costs of HS confirms that the hospital care of patients with this disease is cost-intensive. However, the primary goal of physicians is not and should not be to save costs regarding their patients`treatment, but rather the premise to utilize the existing resources as efficient as possible. Reducing the use of costly therapeutics and inpatient stays therefore requires more effective therapy options with an improved cost-benefit profile.

Improvement in Hidradenitis Suppurativa and Quality of Life in Patients Treated With Adalimumab: Real-World Results From the HARMONY Study

Background

Hidradenitis suppurativa (HS), a chronic, recurrent, debilitating skin disease, is characterized by painful, inflammatory, subcutaneous lesions of the axilla, inguinal and anogenital regions. Overall prevalence of HS is ˜1%, and the impact of disease on patient quality of life (QoL) and healthcare resource utilization (HRU) is high.

Objectives

To estimate the real‐world effectiveness of adalimumab (Humira®) treatment in patients with moderate‐to‐severe HS on disease severity, pain, QoL, work productivity and HRU.

Methods

HARMONY (Effectiveness of Adalimumab in Moderate to Severe HidrAdenitis SuppuRativa Patients – a Multi‐cOuNtry studY in Real Life Setting) is a multicentre, postmarketing observational study in adult patients with moderate‐to‐severe HS. Disease severity and QoL parameters were evaluated using validated measures at 12‐week intervals over 52 weeks of treatment. The primary endpoint was the proportion of patients achieving a Hidradenitis Suppurativa Clinical Response (HiSCR: ≥50% reduction in abscess and inflammatory nodule count, with no increase in abscess and draining fistula counts relative to baseline) at 12 weeks. Secondary endpoints were HiSCR at 24, 36 and 52 weeks and changes in QoL parameters and work productivity assessments. Analyses were conducted using as‐observed data.

Results

The proportion of patients reaching the primary HiSCR endpoint was 70.2% (n = 132/188 enrolled) and remained ≥70% until study completion. There were statistically significant (P < 0.0001) reductions in worst and average skin pain. All of the QoL measures evaluated improved significantly (P < 0.0001) by 12 weeks of adalimumab treatment, as did work productivity assessments (P < 0.05), and there was a ˜50% decrease in HRU between baseline and week 52. Adalimumab was well tolerated.

Conclusions

In this real‐world setting, adalimumab treatment of moderate‐to‐severe HS resulted in decreased disease severity and improvements in QoL and productivity. Response to adalimumab was rapid (within 12 weeks) and sustained (52 weeks). No unexpected safety signals were reported.

Clinical Epidemiology and Management of Hidradenitis Suppurativa

Hidradenitis suppurativa is a chronic immune-mediated inflammatory skin disease with a prevalence of 0.1-1%, characterized by nodules and abscesses in the axillae, groin, and inframammary areas, sometimes developing into tunnels (or fistulas) and scars. Because hidradenitis suppurativa is more common in women and in those aged 18-40 years, obstetrician-gynecologists (ob-gyns) have the opportunity to diagnose, educate, initiate treatment, and coordinate care with ancillary health care professionals. The recently published North American treatment guidelines, along with management information for patients with hidradenitis suppurativa who are pregnant or breastfeeding, are summarized. By diagnosing and optimizing hidradenitis suppurativa treatment early in the disease course, ob-gyns can reduce morbidity, with the potential to favorably alter disease trajectory.

The Burden of Hidradenitis Suppurativa Signs and Symptoms in Quality of Life: Systematic Review and Meta-Analysis

Hidradenitis suppurativa (HS) is a chronic, recurrent and debilitating inflammatory skin disease of the hair follicle that usually presents as painful, deep-seated inflamed lesions in the apocrine gland-bearing areas of the body. HS patients suffer from uncomfortable signs and symptoms, such as pain, pruritus, malodour and suppuration, which may impair patients’ quality of life (QoL). Although HS patients frequently experience these signs and symptoms, they are only occasionally assessed by clinicians and, unexpectedly, the scientific evidence available is limited and heterogeneous. The aim of this study is to summarize the evidence regarding the impact of HS signs and symptoms on QoL to serve as a basis for future research and help clinicians to consider them in the daily care of HS patients. A systematic review and meta-analysis were conducted following PRISMA Guidelines. The following search algorithm was used: (hidradenitis or “acne inversa”) and (pain or itch or odour or malodour or suppuration or oozing or drainage) and (“quality of life”). The literature search identified 836 references, 17 of them met the eligible criteria and were included for analysis, representing 4929 HS patients. Mean age of the participants was 36.28 years and there was a predominance of female sex among study participants. The BMI of the population was in the range of over-weight and about two out five patients were active smokers. Studies included patients with mild to moderate HS, with a mean disease duration of 13.69 years. The HS signs and symptoms assessed were pain, pruritus, malodour and suppuration. Overall, the higher intensity of a sign or symptom correlated with poorer general QoL or specific QoL dimensions including sexual distress, anxiety, depression and sleep. The most frequently employed tool to assess QoL was the Dermatology Life Quality Index (DLQI). DLQI was used in 52.9% of the studies (9/17) with a mean value of 10.70 (2.16 SD). The scores employed to assess signs and symptoms severity were subjective and varied between studies, being the numerical rating scale (NRS) for each of the most used symptoms. The mean NRS value for pain was 3.99 and the mean NRS for pruritus was 4.99. In conclusion, we have summarized, categorized and analyzed the scientific evidence regarding signs and symptoms in HS patients and their impairment in QoL. Their assessment should be thorough and included during routine evaluation of HS patients to motivate therapeutic modifications and increase patients’ health.

Prevalence of depression among children, adolescents, and adults with hidradenitis suppurativa

BACKGROUND

Information on prevalence of depression among children, adolescents, and adults with hidradenitis suppurativa (HS) is limited.

OBJECTIVE

To compare prevalence of depression in HS patients with that of controls.

METHODS

Cross-sectional analysis of 38,140 adult and 1162 pediatric HS patients and controls identified using data from electronic health records. Primary outcome was prevalent depression.

RESULTS

Prevalence of depression among adults with HS was 30.0% (95% Confidence interval [CI], 29.6-30.5), compared with 16.9% (95% CI, 16.7-17.1) among controls. Among children and adolescents with HS, prevalence of depression was 11.7% (95% CI, 10.0-13.7), compared with 4.1% (95% CI, 3.6-4.7) among controls. In adjusted analyses, adults and children/adolescents with HS had 1.26 (95% CI, 1.25-1.28; P < .001) and 1.42 (95% CI, 0.999-2.01; P = .051) times the odds of having depression relative to controls, respectively.

LIMITATIONS

We could not evaluate the influence of disease severity on the outcome.

CONCLUSION

Depression is prevalent among children, adolescents, and adults with HS. Periodic screening for depression may be warranted.

Psychosocial impact of hidradenitis suppurativa: a practical guide for clinicians

INTRODUCTION

Hidradenitis suppurativa (HS) is a debilitating skin disease with significant and often underappreciated effects on quality of life; available treatments fail to achieve consistent rates of remission. Targeting the psychosocial impact of HS has great potential to improve care for these patients. Although the literature on this topic is broad, there is a lack of specific tools that guide clinicians in this domain.

METHODS

The authors surveyed the literature to find the aspects of psychosocial functioning that most significantly impact Health-Related Quality of Life (HRQOL) for HS patients, and which may be assessed in a simple and efficient manner.

RESULTS AND DISCUSSION

Depression and anxiety, sexuality and body image, and financial strain were identified as the most significant drivers of poor HRQOL with the greatest potential to be screened for and addressed succinctly and effectively. A practical psychosocial management guide for clinicians is presented. The guide includes a list of preexisting validated screening questions, clear guidelines for interpretation, and a suggested management algorithm all geared toward a 'real-life' medical practice.

CONCLUSION

Such an approach holds a great potential for improving the care of patients with HS. Validation of this approach via controlled trials is a logical next step.

High inflammation in hidradenitis suppurativa extends to perilesional skin and can be subdivided by lipocalin-2 expression

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease presenting with diverse manifestations ranging from nodules and abscesses to draining tunnels. Whether the underlying inflammation from lesions extends to relatively healthy-appearing adjacent perilesional and distant nonlesional skin has not been systematically evaluated.

OBJECTIVE

We sought to characterize lesional, perilesional, and nonlesional skin in patients with HS.

METHODS

Skin biopsy samples were collected under ultrasound guidance from patients with active, untreated moderate-to-severe HS. Site-matched control biopsy samples from healthy volunteers were used for comparison.

RESULTS

RNA sequencing demonstrated that HS skin clustered separately from healthy control skin, with perilesional and lesion skin clustering together and away from nonlesional skin. Immunohistochemistry analysis identified psoriasiform hyperplasia with keratin 16 positivity in both perilesional and lesional skin, with comparable levels of CD3⁺, CD11c⁺, and neutrophil elastase-positive cellular infiltration. There was a marked upregulation of IL-17 signaling in perilesional and lesional skin. HS samples clustered on the basis of expression of lipocalin-2 (LCN2), with samples characterized by high LCN2 expression in the skin exhibiting a differing transcriptomic profile with significantly higher overall inflammation than that of skin characterized by low LCN2 levels.

CONCLUSIONS

Perilesional HS skin has a transcriptomic and molecular profile comparable to that of lesional skin. HS can be grouped into 2 distinct subtypes based on molecular levels of LCN2 in the skin, with the LCN2-high subtype exhibiting an overall higher inflammatory burden and an upregulation of targetable cytokines. To our knowledge, this is the first study to characterize a unique HS subtype (and a potential endotype) that may guide future therapeutic targets.
