Surgical Management of Hidradenitis Suppurativa: A Narrative Review.

Objective: Hidradenitis suppurativa (HS) is a debilitating, chronic, dermatological inflammatory skin disease that affects apocrine gland bearing skin in the axillae, groin, and inframammary regions. It is underdiagnosed and its pathogenesis incompletely understood. This paper provides a comprehensive review of the existing literature on the surgical management of HS, focusing upon outcomes of definitive surgery. Methods: A literature search was conducted according to PRISMA guidelines. PubMed and EMBASE databases were searched for original studies pertaining to the surgical management of HS published from January 1970 to July 2020. A total of 33 papers were included for analysis. Results: Management options include risk factor modification, pharmacological agents, and surgical intervention. Many surgical management techniques exist, including incision and drainage, CO2 laser therapy, deroofing, wide local excision, and reconstructive surgery. Incision and drainage is commonly utilized for symptom relief of sepsis. While data on curative surgical management are lacking, studies on surgical approaches have shown favorable outcomes in highly selected cases.Wide excision with flap reconstruction results in high patient satisfaction rates, good cosmesis, and reduced disease recurrence. Limitations: A small number of suitable papers met our specific focus and inclusion and exclusion criteria. Novel techniques described in case studies were missed. Additionally, this study examined HS management as a whole, but region-specific management was not reviewed closely. Conclusion: The success of surgical management is dependent on multiple factors. Thus far, the precise role of surgery in elective treatment of refractory HS requires further analysis and reporting of outcomes.

Psychosocial burden and out-of-pocket costs in patients with atopic dermatitis in Ireland.

Atopic dermatitis (AD) is one of the most common inflammatory skin diseases in the developed world, affecting 1-3% of the adult population in Europe. This inflammatory disease can have a marked impact on affected individuals, leading to significant impairment in physical wellbeing and quality of life (QoL). The aim of this study was to investigate the psychosocial impact and financial burden of AD on patients in Ireland. To increase our understanding of the psychosocial and financial aspects of AD disease burden in the Irish population, an online survey was designed. The survey was launched by the Irish Skin Foundation, and included questions focusing on disease severity, disease control, psychosocial impact, interrupted sleep, missed work and school days, and financial cost. The survey showed that the impact of AD on QoL was profound. The survey demonstrated that 85% of adults described interrupted sleep, 70% reported social anxiety, 65% avoid exercise and sports, 52% avoid social activities, 52% avoid sexual intimacy and 43% feel they are depressed as a result of their AD. Approximately one-quarter of those surveyed can spend up to €2300 annually on over-the-counter, prescription and alternative treatments. This study has shown the significant impact AD has on patients living in Ireland. It also highlights that out-of-pocket costs for patients is higher compared with previous studies across European countries.

An Update on Health-Related Quality of Life and Patient-Reported Outcomes in Hidradenitis Suppurativa.

Hidradenitis suppurativa is a common inflammatory skin condition which causes recurrent abscesses, sinuses and scarring in the axillae, groin and inframammary areas. As well as causing significant physical distress due to pain and discharge, the condition impacts psychological well-being with markedly impaired quality of life. Patients suffer pain, embarrassment and psychological distress with impairment of their work and intimate relationships marking it as one of the most distressing dermatological conditions. Numerous studies have documented markers of psychological distress encompassing the physical effects such as pain and itch, affects on mood and impaired function.

A qualitative analysis of psychological distress in hidradenitis suppurativa.

BACKGROUND: Hidradenitis suppurativa (HS) can negatively impact on patients' quality of life and is associated with a higher risk of depression, as well as difficulties in employment and relationships. OBJECTIVES: This study sought to evaluate the lived experience of psychological distress in HS. METHODS: Structured interviews were conducted with 12 participants. These were later transcribed and analysed using thematic analysis. The transcripts and analysis were reviewed by an independent researcher. RESULTS: The results indicated that there were three main themes: shame, pain and coping mechanisms. Participants indicated that their feelings of shame were due to disgust at their symptoms. They feared that others would be disgusted if their symptoms were obvious. Participants reported feeling invalidated when others did not understand the severity of their pain. Additionally, they reported that pain left them with a sense of powerlessness over their own bodies. Regarding coping mechanisms, adaptive strategies included social support while maladaptive strategies included social withdrawal. CONCLUSIONS: These findings are discussed in the context of the existing research on shame, chronic pain and psoriasis. The implications for psychological support for individuals with HS are evaluated. Additionally, the limitations of this study are considered and recommendations for future research are given. This study has highlighted that feelings of shame and physical pain are associated with psychological distress in HS. What's already known about this topic? Hidradenitis suppurativa (HS) has been shown to be associated with physical pain, a higher risk of depression, difficulties in sustaining employment and difficulties in relationships. Additionally, studies using quality-of-life measures have found more impairment in HS than in other dermatological conditions. What does this study add? Although the research to date has determined that there are negative social and emotional consequences associated with HS, the psychological processes underlying these impairments have not yet been looked at. This study aims to get a deeper understanding of the lived experience of psychological distress in HS and how individuals with HS attempt to manage this distress. What are the clinical implications of the work? This study has identified shame as a key feature that underlies the psychological difficulties experienced as a consequence of HS. When deciding upon appropriate psychological interventions for HS, approaches that specifically focus on reducing feelings of shame should be considered.

Could isotretinoin flare hidradenitis suppurativa? A case series.

We report eight cases of patients with severe acne who were treated with isotretinoin and developed painful nodules in the axillae and groin, consistent with hidradenitis suppurativa (HS). The pathogenesis of HS is still not completely understood; recent research from a study in 2011 of biopsies from HS lesions showed a reduction or absence of sebaceous glands compared with normal skin in patients with HS, with the report suggesting that this contributes to the pathogenesis of the disease. Interestingly, the main effect of isotretinoin is to decrease the size and action of sebaceous glands, so hypothetically, as isotretinoin acts by reducing the sebaceous glands further it could potentially aggravate HS. Our experience has instilled caution in our prescribing of isotretinoin, and we question patients, particularly those with acne conglobata, about symptoms of HS prior to and during treatment.

Investigation of the skin microbiome: swabs vs. biopsies.

BACKGROUND: Human skin is populated by diverse bacteria and there is increasing evidence that resident bacteria play a key role initiating immune responses in cutaneous diseases such as atopic dermatitis, psoriasis and hidradenitis suppurativa. Bacteria are present at all layers of the skin but many studies have relied on swabs to profile the skin microbiota. OBJECTIVES: As the pathogenesis of many skin conditions is dermal, we wanted to compare the microbiota obtained in swabs (surface) and biopsies (dermis). METHODS: Using 16S rRNA gene sequencing we established the microbial profiles of skin swabs and skin biopsies in 16 patients. RESULTS: We found differences in both diversity and taxonomic composition of the microbiome obtained from swabs and biopsies of the same individual. Several taxa were found to be more abundant in the swabs, which displayed significantly higher community richness, but Clostridiales and Bacteroidetes were significantly enriched in the biopsies. Most published research on cutaneous microbiota has been based on skin swabs, which represent the surface of the skin. CONCLUSIONS: Our study demonstrated a clear difference between the microbiome observed from skin swabs and skin biopsies. These findings may be highly relevant in disorders such as psoriasis where pathogenesis arises in the dermis. What's already known about this topic? 16S RNA gene sequencing has facilitated study of the skin microbiome. Several studies have sequenced the microbiome sampled by skin swabs. What does this study add? The microbiome data obtained using swabs and biopsies were different. Diseases that are predominantly dermal should be studied using both swabs and biopsies.

A cross-sectional epidemiological study of hidradenitis suppurativa in an Irish population (SHIP).

BACKGROUND: Hidradenitis suppurativa (HS), a chronic inflammatory disease that affects apocrine gland-bearing skin, has a significant impact on patients' quality of life. Estimates of the epidemiologic prevalence of HS are highly variable, and clinical data on disease characteristics and patient burden of disease remain limited. OBJECTIVE: The primary objective of this study was to determine the number of patients with HS attending dermatology clinics in a hospital setting in Ireland (within a 6-month time period). Secondary objectives included the assessment of disease characteristics and the collection of patient responses on disease burden and work productivity. METHODS: This was an epidemiologic, non-interventional, cross-sectional study across four dermatology clinics in Ireland over a 6-month time period. The disease prevalence was estimated by calculating the percentage of total patients with a diagnosis of HS (the primary population) across the selected sites. Secondary analyses were performed using the full analysis set, which consisted of eligible adults (≥18 years of age) from the primary population who provided informed consent. Data from these analyses are presented as descriptive summary statistics, with the use of an analysis of covariance for continuous endpoints. RESULTS: The prevalence of HS across the four selected sites was estimated at 1.4% (95% CI, 1.24-1.62). One hundred and fifty eligible patients comprised the full analysis set. The majority of participants were white (95.3%), female (70.0%), cigarette smokers (56.0%) and overweight or obese (body mass index ≥25 kg/m2 , 81.8%). Most patients for whom data were available presented with Hurley stage II (50.4%), and more than a third of the full analysis set had a relative with HS (34.7%). Questionnaire responses revealed a profound impact on quality of life, including diminished work productivity and various psychological comorbidities. CONCLUSION: This study offers insight into the clinical features and disease burden of hidradenitis suppurativa in an Irish population.

Hidradenitis Suppurativa and Crohn's Disease: A Case Series.

Hidradenitis Suppurativa (HS) is characterized by chronic recurrent abscesses, nodules and draining sinus tracts with scar formation. Cutaneous Crohn's Disease (CD) may also present similarly. We wished to identify and describe an Irish cohort with combined HS and CD, with a view to a better recognition of clinical manifestations and understanding of the pathophysiology underlying these two overlapping conditions. Cases were identified using the HIPE Code at Tallaght Hospital from 1990-2014 and retrospective review was performed. Seven patients with both HS and CD were identified, 5(71%) female. The median age of diagnosis with both conditions was 37 years. In all cases, CD had preceded the diagnosis of HS. All patients smoked. Six had an increased BMI and 43% had additional autoimmune conditions. All patients required treatment with a TNF-alpha inhibitor for HS with 5 of 6 subjects having reduced frequency of flare ups and clinically less active HS on follow up.
