RESUMEN

BACKGROUND: Hidradenitis suppurativa (HS) is a disease with an unmet need for treatment. OBJECTIVE: To examine tolerability, safety and efficacy of oral phosphodiesterase-4 (PDE4) inhibitior orismilast 10-40 mg twice daily (BID) in HS. METHODS: A Phase 2a, single-arm, single-centre, open-label, 16-week trial in HS patients. Adjustments in maximal dose and titration were allowed, to improve tolerability, dividing the study population in two groups who completed and discontinued 16 weeks of treatment. Descriptive statistics were applied to efficacy data from patients who completed treatment and patients who discontinued treatment prematurely. A last-observation-carried-forward (LOCF) approach was used for patients who discontinued treatment. The primary endpoint was percent change in the total number of abscesses and nodules (AN-count) at Week 16, with the HS Clinical Response with a 50% reduction in the AN-count (HiSCR50) as key secondary endpoint. RESULTS: Of the 20 patients included, 9 completed 16 weeks of treatment and 11 discontinued treatment prematurely. The mean AN-count was reduced with 33.1% in patients who completed treatment and with 12.0% in patients who discontinued. HiSCR50 was achieved by 67.0% and 27.0% of patients who completed and discontinued treatment, respectively. Most adverse events were mild to moderate. CONCLUSIONS: Oral orismilast demonstrated a dose-dependent tolerability, with mild to moderate adverse effects. Further, the results of this exploratory trial indicate that orismilast may lead to clinical improvements in HS. However, larger trials with tolerable dose ranges are warranted. The Trial is registered at Clinicaltrials.gov (UNI50007201) and EudraCT.ema.europa.eu (2021-000049-42).

RESUMEN

The European Academy of Dermatology and Venereology (EADV) Task Forces on quality of life (QoL) and patient-oriented outcomes and on urticaria and angioedema recommendations for the assessment of Health-related (HR) QoL in all patients with urticaria in research and practice are as follows: to use the DLQI for adults and the CDLQI for children as dermatology-specific and the CU-Q2oL as a disease-specific HRQoL instruments in urticaria; to use generic instruments to provide comparison of data on urticaria with non-dermatologic diseases, or to compare with healthy volunteers or the general population; to select validated HRQoL instruments with appropriate age limits; to present exact numeric data for HRQoL results; correct title of any HRQoL instrument should be used, along with its correct abbreviation and the reference to its original publication, where possible. The EADV TFs discourage the use of non-validated HRQoL instruments and modified HRQoL instruments that have not undergone standard validation.

RESUMEN

BACKGROUND: Itch as the most common symptom in dermatology has been shown to be related to psychological factors such as stress, anxiety and depression. Moreover, associations were found between perceived stigmatization and itch. However, studies investigating the differences between patients with dermatoses with and without itch regarding perceived stress, stigmatization, anxiety and depression are missing. Therefore, one of the aims of the second study of the European Society for Dermatology and Psychiatry (ESDaP study II) was to investigate these relationships in a large cohort of patients with different itchy dermatoses. RESULTS: 3399 patients with 14 different itchy dermatoses were recruited at 22 centres in 17 European countries. They filled in questionnaires to assess perceived stigmatization, stress, signs of clinically relevant anxiety or depression, itch-related quality of life, the overall health status, itch duration, frequency and intensity. The most significant association between the severity of itching and the perception of stress was observed among individuals with rosacea (correlation coefficient r = 0.314). Similarly, the strongest links between itch intensity and experiences of stigmatization, anxiety, and depression were found in patients with seborrheic dermatitis (correlation coefficients r = 0.317, r = 0.356, and r = 0.400, respectively). Utilizing a stepwise linear regression analysis, it was determined that within the entire patient cohort, 9.3% of the variation in itch intensity could be accounted for by factors including gender, levels of anxiety, depression, and perceived stigmatization. Females and individuals with elevated anxiety, depression, and perceived stigmatization scores reported more pronounced itch intensities compared to those with contrary attributes. CONCLUSION: This study underscores the connection between experiencing itch and its intensity and the psychological strain it places on individuals. Consequently, psychological interventions should encompass both addressing the itch itself and the interconnected psychological factors. In specific cases, it becomes imperative for dermatologists to direct individuals towards suitable healthcare resources to undergo further psychological assessment.

RESUMEN

BACKGROUND: Dysmorphic concern is an overconcern with an imagined or slight defect in physical appearance that can be a symptom of body dysmorphic disorder (BDD). Appearance-related concerns are frequently reported by people with dermatological conditions. However, relatively little remains known about the relationship between dysmorphic concern and other variables within persons with different skin conditions. OBJECTIVES: The aim of this multicentre, cross-sectional study was to investigate gender differences regarding dysmorphic concern and the prevalence of BDD in a large sample of patients with skin conditions, in relation to sociodemographic, clinical and psychological variables. METHODS: Participants aged ≥18 years with skin conditions were consecutively enrolled in dermatological clinics of 22 European centres. Dysmorphic concern and the possible presence of BDD were measured using the Dysmorphic Concern Questionnaire (DCQ) and compared between men and women in relation to sociodemographic, clinical and psychological variables, and separately for each skin condition. RESULTS: The DCQ questionnaire was completed by 5290 dermatological patients. In all categories, mean scores were significantly higher in women than in men. Mean DCQ scores were also higher in women for most skin conditions, with the highest effect size in vitiligo. The percentage of patients who screened positive for BDD on the DCQ was 10.5%, 7.7% of men and 12.7% of women. The prevalence of BDD positive was 6.9% in patients with mild clinical severity, 11.1% for moderate and 19.1% for severe condition. In the multivariate model in patients with mild skin condition, the presence of BDD was positively associated with stress and stigma both in men and in women. CONCLUSIONS: Dysmorphic concern and BDD were more frequent in women than in men with skin conditions. Both received and actual stigmatization might have an impact on body-related concerns, in particular in women, who may be more at risk for sociocultural reasons.

RESUMEN

BACKGROUND: To minimize the risk of incomplete excision of basal cell carcinomas (BCC) the macroscopic tumor margins should be adequately defined. Optical coherence tomography (OCT) is a non-invasive imaging tool that can provide structural and vascular information about skin cancer lesions. The study objective was to compare the presurgical delineation of facial BCC by clinical examination, histopathology, and OCT imaging in tumors undergoing full excision. METHODS: Ten patients with BCC lesions on the face were examined clinically, with OCT and histopathology at 3-mm intervals, from the clinical lesion border and beyond the resection line. The OCT scans were evaluated blinded and a delineation estimate of each BCC lesion was made. The results were compared to the clinical and histopathologic results. RESULTS: OCT evaluations and histopathology were in agreement in 86.6% of the collected data points. In three cases the OCT scans estimated a reduction of the tumor size compared to the clinical tumor border set by the surgeon. CONCLUSION: The results of this study support the notion that OCT can have a role in the clinical daily practice by aiding clinicians in delineating BCC lesions before surgery.

RESUMEN

PURPOSE: The burden of different skin diseases may vary leading individuals to have different sensitivity to stress. Therefore, we compared the health-related quality of life (HRQoL) and stress before and during the universal stress from the severe acute respiratory syndrome coronavirus-2-pandemic in individuals with and without hyperhidrosis, hidradenitis suppurativa, or psoriasis. METHODS: The study cohort was the Danish Blood Donor Study. Overall, 12,798 participants completed a baseline questionnaire before the pandemic, in 2018-2019, and a follow-up questionnaire during the pandemic, in 2020. Regression determined the association between the skin diseases and outcomes. Outcomes were the physical and mental component summary (MCS, PCS, respectively), which assess the mental and physical HRQoL, and the perceived stress scale, which assesses stress in the past four weeks. RESULTS: Overall, 1168 (9.1%) participants had hyperhidrosis, 363 (2.8%) had hidradenitis suppurativa, and 402 (3.1%) had psoriasis. At follow-up, the participants with hyperhidrosis had worse MCS (coefficient -0.59 [95% confidence interval (CI) -1.05, -0.13]) and higher odds of moderate-to-severe stress (odds ratio 1.37 [95% CI 1.13, 1.65]) and the participants with hidradenitis suppurativa worse PCS (coefficient -0.74 [95% CI -1.21, -0.27]) than the control groups. The associations were independent of baseline HRQoL, stress, the Connor-Davidson Resilience scale, and other covariables. Psoriasis was not associated with the outcomes. CONCLUSION: Individuals with hyperhidrosis or hidradenitis suppurativa experienced worse mental or physical well-being and individuals with hyperhidrosis also had higher stress during the pandemic compared to healthy individuals. This suggests that individuals with these skin diseases are particularly susceptible to external stress.

RESUMEN

BACKGROUND: Hidradenitis suppurativa (HS) is a recurrent inflammatory skin disease that, apart from rare causative loss-of-function mutations, has a widely unknown genetic aetiology. OBJECTIVES: To estimate the relative importance of genetic and environmental factors underlying susceptibility to HS. METHODS: Via the Danish Twin Registry and the Danish National Patient Registry we pulled together information on zygosity with that of HS status. Cases of HS were identified by the International Classification of Diseases (ICD)-8 (705·91) and ICD-10 (L73·2). Heritability was assessed by the classic biometric model and the possibility of gene-gene interaction via the multilocus modelling approach. RESULTS: Among 100 044 registered twins, we found 170 twins (from 163 pairs) diagnosed with HS. The seven concordant pairs were all monozygotic. Monozygotic twins had a case-wise concordance rate of 28% [95% confidence interval (CI) 7-49], corresponding to a familial risk of 73 (95% CI 13-133) times that of the background population. The biometrical modelling suggested a heritability of 0·80 (95% CI 0·67-0·93), and the multilocus index estimate was 230 (95% CI 60-400). This is highly indicative of gene-gene interactions, with the possibility of up to six interacting loci. CONCLUSIONS: This twin study was substantially larger and employed a more valid phenotype than previous studies. Genetics account for the majority of HS susceptibility, and HS is most likely caused by gene-gene interactions rather than monogenetic mutations or solely additive genetic factors. New approaches aimed at assessing potential interactions at a single-nucleotide polymorphism (SNP)-SNP level should be implemented in future HS genome-wide association studies.

RESUMEN

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory disease influenced by genetics, non-genetic and environmental factors that modulate miRNA expression. Currently, no miRNA data are available for HS. In this study, we profiled DNA methylation patterns of miRNA genes associated with HS susceptibility. OBJECTIVES: Identify miRNA gene methylation profiles associated with HS susceptibility. This study examined the methylation patterns of DNAs from 24 healthy controls and 24 patients with HS using Illumina Infinium MethylationEPIC BeadChip array analysis. Methylation patterns of miRNA genes were analysed using KEGG pathway analysis to explore the inversely correlated pathways regulated by miRNAs. RESULTS: We identified 60 CpG sites representing 65 unique microRNA genes including 54 hypomethylated and 6 hypermethylated CpGs as potentially associated with HS. Some of these CpGs were found to be critical for skin function, such as miR-29, miR-200, miR-205, miR-548 and miR-132. The miR-192 is implicated in non-alcoholic fatty liver disease. The miR-200c gene was identified as a vital determinant in regulating skin repair after injury and may contribute to age-associated alterations in wound repair. miR-132 was significantly upregulated during the inflammation phase of wound repair, enhancing the activity of STAT3 and ERK pathways that promote keratinocyte proliferation. CONCLUSIONS: Epigenetically altered microRNA genes are implicated in wound healing, inflammation, keratinocyte proliferation and wound modulation. This is the first study to analyse methylation profiles of miRNA genes in the HS population, highlighting the unique role that miRNAs might play in diagnosing and treating HS.

RESUMEN

BACKGROUND: Research on hyperhidrosis comorbidities has documented the co-occurrence of diseases but has not provided information about temporal disease associations. OBJECTIVE: To investigate the temporal disease trajectories of individuals with hospital-diagnosed hyperhidrosis. METHODS: This is a hospital-based nationwide cohort study including all patients with a hospital contact in Denmark between 1994 and 2018. International Classification of Diseases version-10 diagnoses assigned to inpatients, outpatients and emergency department patients were collected from the Danish National Patient Register. The main outcome was the temporal disease associations occurring in individuals with hyperhidrosis, which was assessed by identifying morbidities significantly associated with hyperhidrosis and then examining whether there was a significant order of these diagnoses using binomial tests. RESULTS: Overall, 7 191 519 patients were included. Of these, 8758 (0.12%) patients had localized hyperhidrosis (5674 female sex [64.8%]; median age at first diagnosis 26.9 [interquartile range 21.3-36.1]) and 1102 (0.015%) generalized hyperhidrosis (606 female sex [59.9%]; median age at first diagnosis 40.9 [interquartile range 26.4-60.7]). The disease trajectories comprised pain complaints, stress, epilepsy, respiratory and psychiatric diseases. The most diagnosed morbidities for localized hyperhidrosis were abdominal pain (relative risk [RR] = 121.75; 95% Confidence Interval [CI] 121.14-122.35; P < 0.001), soft tissue disorders (RR = 151.19; 95% CI 149.58-152.80; P < 0.001) and dorsalgia (RR = 160.15; 95% CI 158.92-161.38; P < 0.001). The most diagnosed morbidities for generalized hyperhidrosis were dorsalgia (RR = 306.59; 95% CI 302.17-311.02; P < 0.001), angina pectoris (RR = 411.69; 95% CI 402.23-421.16; P < 0.001) and depression (RR = 207.92; 95% CI 202.21-213.62; P < 0.001). All these morbidities were diagnosed before hyperhidrosis. CONCLUSIONS: This paper ascertains which hospital-diagnosed morbidities precede hospital-diagnosed hyperhidrosis. As hyperhidrosis mainly is treated in the primary health care sector, the trajectories suggests that these morbidities may lead to a worse disease course of hyperhidrosis that necessitates treatment in hospitals. Treating these morbidities may improve the disease course of hyperhidrosis.

RESUMEN

BACKGROUND: A large discrepancy between physician-diagnosed and self-reported Hidradenitis suppurativa (HS) exists. Knowledge regarding incidence and remission rates of self-reported HS is missing, but may help bridge the gap in understanding between these two phenotypes. OBJECTIVES: To determine the incidence and remission rates of self-reported HS, and to what degree these are affected by sex, smoking and BMI. METHODS: A prospective cohort of 23 930 Danish blood donors. Information on self-reported HS, symptom-localisation, sex, age, BMI and smoking status was collected at baseline and study termination. Self-reported HS fulfilled clinical obligatory diagnostic criteria. Cox proportional hazards regression analyses were conducted for both incidence and remission rates providing a hazard ratio (HR) of risk for each variable in the regression. RESULTS: Incidence rate of self-reported HS was 10.8/1000 person-years (95% confidence interval (CI): 9.9-11.7), decreasing as a function of numbers of areas affected. Female BMI points above 25 (HR = 1.11, 95% CI: 1.09-1.13), male BMI points above 25 (HR = 1.07, 95% CI: 1.04-1.11), active smoking (HR = 1.72, 95% CI: 1.15-2.57), male sex (HR = 0.55, 95% CI: 0.45-0.67) and years of age above 25 (HR = 0.97, 95% CI: 0.96-0.97) were all statistically associated with the development of self-reported HS. Remission rate of self-reported HS was 256.7/1000 person-years (95% CI: 223.9-292.6), decreasing as a function of numbers of affected areas. Symptoms in ≥3 areas (HR = 0.54, 95% CI: 0.34-0.85), active smoking (HR = 0.49, 95% CI: 0.32-0.76) and female weight loss (every percentage drop in BMI: HR = 1.07, 95% CI: 1.05-1.11) all significantly affected the remission rate. CONCLUSIONS: Both incidence and remission rates of self-reported HS are high, indicating that many with self-reported HS are unlikely to be diagnosed, as they to a higher degree experience mild transient HS symptoms.

RESUMEN

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory disease. The HS core outcome set calls for a patient global assessment (PtGA). OBJECTIVES: To assess the validity, reliability and responsiveness of a candidate single-item PtGA for HS-specific health-related quality of life (HRQoL). METHODS: Cognitive debriefing interviews were conducted with patients with HS in Denmark and the USA. A cross-sectional observational study was done with adults with HS in the USA and Denmark. Candidate PtGA item, demographic items and multiple patient-reported scales - the Hidradenitis Suppurativa Quality of Life (HiSQOL), Dermatology Life Quality Index (DLQI) and numerical rating scale (NRS) for pain - were concurrently administered to evaluate convergent and known-groups validity. Scales with a single-item assessment of change were readministered 24-72 h later, to evaluate reliability and responsiveness. RESULTS: After cognitive debriefing, the candidate PtGA for HS-specific HRQoL was finalized with five response levels. Convergent validity of the PtGA was supported by significant correlations with HiSQOL score [r = 0·79, 95% confidence interval (CI) 0·75-0·82] and DLQI (r = 0·78, 95% CI 0·74-0·82). The PtGA displayed known-groups validity with DLQI score bands based on significance of an anova (P < 0·001). Good test-retest reliability was supported by the intraclass correlation coefficient (0·82, 95% CI 0·78-0·85) for those who reported stable HS. Responsiveness was assessed by differences in PtGA score against a patient-reported assessment of change, which showed significant differences towards improvement. CONCLUSIONS: The single-item PtGA exhibits reliability, validity and responsiveness in assessing HS-specific HRQoL in HS, making it a good provisional tool for HS clinical research.

RESUMEN

Basal cell carcinoma (BCC) is the most common type of cancer and an increasing incidence stimulates the interest in new treatments such as electrochemotherapy (ECT) with bleomycin. This systematic review focuses on literature from the MEDLINE, Embase, Web of Science, and Cochrane databases. Bleomycin-ECT studies (n = 32) were sorted by the level of evidence adjusted for their BCC data only. The studies included a single randomised controlled trial (RCT), 15 uncontrolled clinical trials, three registry studies, six prospective case series and seven retrospective case series. A Cochrane risk-of-bias assessment of the RCT identified some minor concerns but no predicted risk of bias. The studies were also grouped by bleomycin administration routes: intravenous (n = 14), intralesional (n = 9) and mixed reporting/usage (n = 9). A meta-analysis was not conducted due to the lack of RCTs and the heterogeneity of the included studies. The results of the RCT generally reflected the findings of the other included studies and showed a 92% complete response in 65 bleomycin-ECT-treated BCCs after 2 months, improving to 100% after re-treatment, with a low risk of recurrence. Based on the RCT results and overall data, future studies on BCC treatment with bleomycin-ECT should include large RCTs that compare bleomycin-ECT with standard of care, cost analyses, and clinical feasibility.

RESUMEN

Tinea capitis is a fungal infection mostly affecting children. Epidemiology is changing over time due to migration, and it has been estimated that up to 40% of children from certain developing countries are affected. The mechanism of transmission is still unclear although asymptomatic carriage seems to have an influence in establishing persistent reservoirs that can cause or fuel epidemics. Screening and prophylactic treatment of close contacts of tinea capitis patients are therefore recommended by several international guidelines, but vaguely and not consistent. The treatments involved can be expensive, hard to integrate in everyday life, have well-known side effects and some are not approved for the treatment of children. The aim of this review was to clarify the evidence behind treatment of human asymptomatic carriers of tinea capitis. Databases were searched for the 'tinea capitis', 'carriers' and 'treatment'. Inclusion criteria were clinical trials, observational and interventional studies including case series (10+ cases) and case reports in English, Danish, Swedish, Norwegian and French. Reviews, guidelines, unclear reports and in vitro trials were excluded. A systematic review identified 10 studies with low to moderate evidence levels. The topical treatments ketoconazole, povidone-iodine, miconazole and the systemic antifungals terbinafine and itraconazole have all shown significant effects in the mycological eradication of fungal conidia. General prophylactic hygienic measures may have a benefit. The scientific evidence behind the treatment of asymptomatic carriage of scalp dermatophytes is sparse and not of high quality. Yet, both topical and systemic antifungal agents show treatment efficacy. Considering the possible adverse effects, topical agents are preferable, but with necessary attention to the compliance of asymptomatic contacts with treatment.

RESUMEN

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that severely impairs patients' quality of life. It is characterized by recurrent painful nodules, abscesses and draining sinus tracts in primarily intertriginous areas. We aimed to review the most up-to-date information regarding the epidemiology, clinical presentation, diagnostic studies, pathogenesis, comorbidities and quality of life of patients with hidradenitis suppurativa. We performed a systematic search of Medline, Embase database (from inception to September 2019) and review of bibliographies without restrictions on year or language. HS has an estimated global prevalence of 0.00033-4.1% (but most likely 0.7-1.2% in the European-US population). Patients still experience a significant diagnostic delay, up to several years. In the absence of pathognomonic tests, the diagnosis of HS is made from clinical observation and the disease narrative. Phenotypic variation renders diagnosis and severity assessment difficult. Ultrasound imaging is an emerging assessment tool for deep-seated lesions. The Hurley Staging System is still widely used in severity rating. Follicular hyperkeratosis and dilatation, follicular rupture and chronic inflammation with architectural tissue changes have been implicated in the pathogenesis of HS. HS has been associated with metabolic syndrome and other risk factors for cardiovascular disease, diabetes mellitus type II, polycystic ovarian syndrome, depression, suicide and substance use disorders. It has been linked to other immune-mediated diseases such as inflammatory bowel disease and spondyloarthropathy. Pain, pruritus, malodour, low self-esteem, sleep and sexual dysfunctions, and poor mental health are chronic symptoms or consequences of uncontrolled disease. HS is an under-diagnosed and under-treated disease with a profound negative impact on patients' quality of life. In the light of its associated comorbidities, an interdisciplinary management approach may be needed to ensure the best outcomes.

RESUMEN

BACKGROUND: Hidradenitis suppurativa (HS) is a painful chronic, recurrent inflammatory skin disease with great impact on health-related quality of life (HRQOL). Recently, Hidradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC) established HRQOL as a core domain set for HS clinical trials and developed the Hidradenitis Suppurativa Quality of Life (HiSQOL) as a validated outcome measurement instrument. OBJECTIVES: To provide further convergent validity of HiSQOL by comparing it to Dermatology Life Quality Index (DLQI) and Pictorial Representation of Illness and Self Measure-Revised 2 (PRISM-R2). METHODS: In this cross-sectional study, 103 participants completed HiSQOL, PRISM-R2 and DLQI. PRISM-R2 is an instrument designed to measure suffering and reports the two measures, Illness Perception Measure (IPM) and Self-Illness Separation (SIS). Correlation analyses were performed including a sub-analysis for a subgroup of patients with high scores in the HS-specific domains of HiSQOL. RESULTS: A very strong correlation was found between HiSQOL and DLQI (ρ = 0.93, P < 2.2 × 10-16 , (95% CI: 0.89;0.95)), and moderately strong correlations were found between HiSQOL and SIS (ρ = -0.73, P < 2.2 × 10-16 , (95% CI: -0.81; -0.62)) and DLQI and SIS (ρ = -0.70, P < 2.2 × 10-16 , (95% CI: -0.79; -0.59)). IPM was positively associated with HiSQOL and DLQI and negatively with SIS. CONCLUSIONS: HiSQOL is a valid measure of quality of life for HS patients, and we suggest that HiSQOL can be used as a measure of suffering as well.

RESUMEN

BACKGROUND: Dynamic optical coherence tomography (D-OCT) allows in vivo visualization of blood vessels in the skin and in malignant tumours. Vessel patterns in malignant melanoma may be associated with tumour stage. OBJECTIVE: The aim of this study was to describe blood vessel patterns in melanomas and to correlate them with stage. METHODS: One hundred fifty-nine malignant melanomas were assessed in a multicentre study. Every tumour was imaged using D-OCT prior to surgery and histologic evaluation. The tumour data such as thickness and ulceration as well as the staging at primary diagnosis and a follow-up of at least 40 months resulted in a stage classification. The vessel patterns were assessed according to predefined categories, compared with healthy adjacent skin, and correlated to stage. RESULTS: Melanomas contained more blood vessels in different patterns compared with healthy adjacent skin. In particular, irregular vascular shapes such as blobs, coils, curves and serpiginous vessels were more common in melanomas. In addition, these patterns were significantly more often found in high-risk and metastatic melanomas than in low-risk lesions. CONCLUSION: In melanomas, the density of the blood vessels is increased, and irregular vascular patterns are more frequent. At higher stages, especially in metastatic melanomas, these atypical vessels are significantly more common.

RESUMEN

BACKGROUND: Atopic dermatitis (AD) is a prevalent chronically relapsing inflammatory skin disease of childhood. However, little is known about self-reported trigger factors, impact on daily life and factors associated with AD severity. METHODS: A nationwide questionnaire study of children in Denmark with hospital-diagnosed AD in the time period 2014-2018. The web-based questionnaire was completed by the legal parents. AD severity was assessed using Patient-Oriented Eczema Measure (POEM) tool. RESULTS: Of 3438 invited parents, 1343 (39%) completed the questionnaire. Factors associated with severe AD were onset during the first 6 months of life, onset of AD on multiple body regions, a history of hay fever, female sex and low maternal educational level. Staying home from daycare or school due to AD, concentration problems and sleep disturbances in the child were more frequently reported by parents to children with severe AD. Overall, 90% reported at least one AD trigger factor, and all were more frequently reported in children with severe AD. The three most commonly reported trigger factors were cold weather (51.9%), chlorinated water (35.7%) and warm weather (30.2%). CONCLUSIONS: We identified factors associated with severe AD in childhood, the impact on daily life, as well as the most common self-reported triggers of AD. These findings may be valuable in clinical practice to inform about prognosis and educate families about trigger avoidance.

RESUMEN

BACKGROUND: Hidradenitis suppurativa (HS) is not a well-studied or easily treated disease. Genetic information is essential for advances in the understanding and treatment of HS. This study aims to examine mutations in the gamma-secretase complex, the Notch signalling pathway and to perform a Mendelian analysis of genetic variants that segregated with disease in a full exome sequencing of 11 families with HS. METHOD: Whole-exome sequencing and Mendelian analysis of 11 families with HS from Denmark. Patients with a clinical diagnosis of active HS and a positive family history of HS were recruited. Consenting family members were enrolled and examined for HS as well. We included 11 families, with a total of 51 participants, 24 with HS and 27 without. Whole-exome sequencing using HiSeq platform as paired-end 2 × 150 bases was used. RESULTS: We found mutations in the Notch pathway for all families. We found mutations in the PSENEN and APH1B of the gamma-secretase genes. We also report 161 variants of unknown significance that segregated with the disease within these families. CONCLUSIONS: We did not find causative mutation for each family in this study, supporting the theory that HS is rarely caused by single-gene mutations. We suggest that future genetic studies should be focused on genome-wide association with thousands of cases, as this technique is better suited for suspected polygenic diseases.

RESUMEN

New treatment options may lead to an increased interest in using reliable and sensitive instruments to assess health-related quality of life in people with alopecia areata (AA). The purpose of this paper is to present current knowledge about quality of life assessment in AA. The dermatology-specific Dermatology Life Quality Index (DLQI) was the most widely reported health-related quality of life instrument used in AA. Three AA-specific (Alopecia Areata Symptom Impact Scale, Alopecia Areata Quality of Life Index and Alopecia Areata Patients' Quality of Life) and three hair disease-specific instruments (Hairdex, Scalpdex and 'hair-specific Skindex-29') were identified with a range of content and validation characteristics: there is little evidence yet of the actual use of these measures in AA. Scalpdex is the best-validated hair disease-specific instrument. Further extensive validation is needed for all of the AA-specific instruments. The European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes recommends the use of the dermatology-specific DLQI questionnaire, hair disease-specific Scalpdex and the alopecia areata-specific instruments the Alopecia Areata Symptom Impact Scale or Alopecia Areata Quality of Life Index, despite the limited experience of their use. We hope that new treatment methods will be able to improve both clinical signs and health-related quality of life in patients with AA. In order to assess the outcomes of trials on these new treatment methods, it would be helpful when further development and validation of AA-specific instruments is being encouraged and also conducted.

RESUMEN

BACKGROUND: Pain is a prominent symptom of hidradenitis suppurativa (HS) and has been defined as a domain in the Core Outcome Set for the disease. Quality and intensity of pain is influenced by depression and anxiety, both of which are associated with HS. OBJECTIVES: To describe HS-related pain quantitatively and qualitatively; and to investigate how disease severity, depression and anxiety correlate with self-reported pain quality. METHODS: Pain perception was investigated using the McGill Pain Questionnaire. Symptoms of depression and anxiety were examined using the Hospital Anxiety and Depression Scale. Statistical analyses investigated differences in number of words chosen (NWC) and pain-rating index rank [PRI(R)] in patients with severe disease and in patients with depression/anxiety. RESULTS: A total of 138 patients with HS were recruited in an outpatient clinic (October 2017-March 2018). Patients presented a median NWC of 11·5 and a PRI(R) of 59·0%. Most common descriptors were 'shooting' (83%), 'itchy' (79%) and 'blinding' (75%). Patients with depression or anxiety presented significantly higher PRI(R)s [depressed 65% vs. non-depressed 57% (P = 0·015); anxious 65% vs. nonanxious 57% (P = 0·004)]. Patients with involvement of three or more HS regions vs. those with fewer than three involved regions exhibited a significantly higher NWC (13 vs. 8; P = 0·048). CONCLUSIONS: HS-related pain includes nociceptive and neuropathic pain, and perception appears to be influenced by disease severity, anxiety and depression. A multimodal pain management strategy may be the most appropriate; however, more detailed studies are necessary to define recommendations on pain management. What's already known about this topic? Pain is a core outcome domain hidradenitis suppurativa. Few studies have addressed this significant clinical problem. What does this study add? This study suggests that HS pain comprises both nociceptive and neuropathic pain. Pain appears associated to depression, anxiety and severity of the disease.
