Project description:BackgroundValidated, reliable, globally accepted outcome measurement instruments for hidradenitis suppurativa (HS) are needed. Current tools to measure the physical signs domain for HS rely on lesion counts, which are time-consuming and unreliable.ObjectivesTo assess the reliability and validity of the Hidradenitis suppurativa Area and Severity Index Revised (HASI-R) tool, a novel method for assessing HS severity, incorporating signs of inflammation and body surface area involved.MethodsThe measurement properties of the HASI-R tool were evaluated. The tool was created by combining the previously published HASI and Severity and Area Score for Hidradenitis instruments. Twenty raters evaluated 15 patients with HS in a hospital-based ambulatory dermatology clinic. The objectives of the study were to assess inter- and intra-rater reliability of the HASI-R and its components, as well as its construct and known-groups validity. Existing lesion count-based clinician-reported measures of HS and their components were also assessed. Raters were also asked their preferences regarding the various HS severity assessment tools.ResultsThe HASI-R had moderate inter-rater reliability [intra-class correlation coefficients (ICC) 0·60]. This was better than all other HS physical sign outcome measures evaluated, which had poor inter-rater reliability (ICC < 0·5). HASI-R had the highest intra-rater reliability (ICC 0·91). The HASI-R had good construct validity and demonstrated known-groups validity. The HASI-R was also the most preferred tool by all raters.ConclusionsResults from the clinometric assessment of the HASI-R are encouraging, and support continued evaluation of this clinician-reported outcome measure.

Project description:BackgroundHidradenitis suppurativa (HS) is a chronic, inflammatory skin disease with a large impact on patients' health-related quality of life. However, reliable and consistent outcome measures to assess body surface area (BSA) of HS have not been established.ObjectivesTo develop and assess the reliability and validity of a novel outcome instrument for assessment of HS BSA in a clinical trial setting.MethodsQualitative interviews and focus groups were conducted from July to August 2015 and October 2017 to January 2018. Evaluation of the measurement was assessed during a single-day grading session with patients in April 2018. Participants, who included clinicians or patients, were recruited from academic medical centres in the U.S. mid-Atlantic region.ResultsConcept elicitation included input from 10 providers, of which 60% (n = 6) were female, 80% (n = 8) dermatology specialists and 20% (n = 2) gynaecology specialists. Cognitive debriefing was conducted with 11 providers, of which 82% (n = 9) were dermatologists and 18% (n = 2) gynaecologists. The evaluation stage included 10 clinicians and 23 patients. The intraclass correlation coefficient (ICC) for inter-rater reliability was 0·60 [95% confidence interval (CI) 0·44-0·74]. The ICC for intrarater reliability was 0·98 (95% CI 0·94-1·00). Transformation of the BSA score resulted in an increase in inter-rater reliability to 0·75 (95% CI 0·62-0·85) or 0·76 (95% CI 0·62-0·85). Scores all demonstrated concurrent validity, with statistically significant correlations with extant scoring methods.ConclusionsThis novel scale is a reliable and valid HS outcome instrument and may capture a wide range of patients by assessing BSA. Future research is necessary to demonstrate its responsiveness. What's already known about this topic? The major HS disease activity scales rely on lesions counts and have moderate-to-good reliability. Body surface area (BSA) is one of the physical signs included in the Core Outcome Set for HS, but is not a part of existing HS disease activity scales. What does this study add? A novel disease severity scale, the Severity and Area Score for Hidradenitis (SASH), was developed and the psychometric properties assessed. There was high inter-rater reliability of 0·75 and 0·76 when BSA was scored on an ordinal scale, and an excellent intrarater reliability of 0·98. The SASH score also demonstrated convergent validity with extant instruments. What are the clinical implications of this work? The ability of clinicians to accurately assess disease status will be improved. Implementation of the SASH score will help guide and assess the effectiveness of appropriate treatment choice.

Project description:ImportanceThe variation in both clinical appearance and responses to diverse treatment options emphasize the importance of an accurate, clinically relevant, yet easy-to-use scoring system in hidradenitis suppurativa.ObjectiveTo propose and provide validation data for the newly designed Severity Assessment of Hidradenitis Suppurativa score.Design, setting, and participantsWe prospectively assessed disease severity using Hurley staging and the modified Hidradenitis Suppurativa Score in 355 patients referred to Ruhr-University Bochum Department of Dermatology between March 2016 and June 2017. We also assessed disease severity via the Severity Assessment of Hidradenitis Suppurativa score.Main outcomes and measuresEvaluation and assessment of convergent validity and responsiveness to treatment of the Severity Assessment of Hidradenitis Suppurativa score.ResultsEighty-eight of the 355 patients (134 [37.7%] men and 221 [62.3%] women with a median [IQR] age of 40 [30-49] years) were classified as Hurley stage I, 221 were Hurley stage II, and 46 were Hurley stage III, with an overall median modified Hidradenitis Suppurativa Score of 31 (interquartile range [IQR], 19.3-53). The median total Severity Assessment of Hidradenitis Suppurativa score was 6 (IQR, 4-9), significantly different among the 3 Hurley groups. The median SAHS score for patients in Hurley stage I was 5 (IQR, 3-6), 6 (IQR, 5-9) for patients in Hurley stage II, and 9 (IQR, 7-12) for patients in Hurley stage III (P < .001, Kruskal-Wallis test). Correlation analysis showed a significant correlation between the modified Hidradenitis Suppurativa Score and the Severity Assessment of Hidradenitis Suppurativa score (r = 0.79, P < .001). Disease severity assessment before and after 3 months of conservative systemic treatment showed a significant correlation between the Severity Assessment of Hidradenitis Suppurativa score and modified Hidradenitis Suppurativa Score. Both the mHSS (P = .001) and the SAHS score (P < .001) significantly differed between the baseline visit (median mHSS, 33 [IQR, 24-52]; median SAHS score, 6 [IQR, 5-9]) and the 3-month visit (median mHSS, 28 [IQR, 15-43.5]; median SAHS score, 5 [IQR, 4-6.3]). The 2 patient-reported items demonstrated excellent test-retest reliability with intraclass correlation coefficient values greater than 0.8.Conclusions and relevanceOur validation data demonstrated that the Severity Assessment of Hidradenitis Suppurativa score is a disease severity instrument that significantly correlates with Hurley staging and the modified Hidradenitis Suppurativa Score, and is responsive enough to measure treatment outcome.

Project description:Hidradenitis suppurativa (HS) is a chronic debilitating disorder that can affect any areas bearing apocrine glands. Perineal HS is associated with high morbidity compared with other anatomic regions. Early-stage disease may mimic various other forms of cutaneous disorders, but as HS progresses pathognomonic skin changes occur. Clinical stage can guide the therapeutic approach, but the lowest recurrence rate is obtained by removing all involved skin and subcutaneous fat. Pruritus ani is a complex disease with a multitude of etiologies. Its management can be frustrating and disappointing for the patient and doctor alike. The key is to start with simple treatment options focusing on perianal hygiene and avoidance of the most common offending foods and beverages. If these measures fail, topical medications should be attempted before graduating to perianal injections of methylene blue as a last resort.

Project description:IntroductionHidradenitis 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.MethodsThe 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.ResultsThe 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.ConclusionThe 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.

Project description:Hidradenitis Suppurativa is a burdensome inflammatory skin disease with significant quality of life impact. These management guidelines were developed to direct appropriate clinical management in the Australasian context. A systematic review was used for the basis of the consensus guidelines. Thirteen clinical experts were involved in a modified Delphi consensus process to develop the guidelines and treatment algorithms. Overall management strategies include appropriate severity assessment of disease and comorbidities, multimodal therapy with systemic and local treatments, and evidence-based progression along the therapeutic ladder in the event of inadequate response. Sequential monotherapy with antibiotics and/or single agent therapy is discouraged and aggressive treatment of moderate to severe disease to capture the window of opportunity is highly emphasised. Specific considerations in the setting of disease comorbidities, pregnancy and breastfeeding are also addressed. Overall, the complex nature of HS requires a complex and multimodal therapeutic response with medical, physical and surgical therapies to achieve best patient outcomes.

Project description:Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with severe consequences on quality of life. One aspect of this is that HS has been linked to an increased risk of infertility, but as data is still limited, it is not known if the association reflects causality. We performed a cross-sectional study of 161 female participants included at Zealand University Hospital, Roskilde, Denmark. Data regarding basic demographics, infertility, pregnancies, sexual function, and known factors with impact on fertility was collected. Logistic regressions were performed to analyze the association between HS and infertility, adjusting for factors that influence fertility. The study population consisted of 55 patients with HS, 55 patients with other dermatological diseases (ODD), and 51 healthy controls (HC). The HS group had a higher BMI, lower sexual function, and a higher tobacco use. We found no significant difference between the three groups in terms of whether they had children, the number of children they had, infertility, or whether they had received fertility treatments. The logistic analyses found no correlation between HS and infertility, and adjusting for factors affecting infertility did not alter this result. This study did not find a significant difference in infertility between patients with HS compared to those with ODD or HC. This result was not affected by adjustments for other factors known to influence fertility. Interestingly, the lower sexual function in the HS group did not appear to influence their desire or ability to conceive.
