Thyroid Disease and Active Smoking May Be Associated with More Severe Hidradenitis Suppurativa: Data from a Prospective Cross Sectional Single-Center Study.

INTRODUCTION: Hidradenitis suppurativa (HS) is an obscure disease presenting with painful, deep-seated nodules and abscess formation in body areas rich in apocrine glands. Several factors, including thyroid disease and active smoking, have been reported to be associated with HS, but it remains unclear if such associations are related to clinical HS severity. The aim of this prospective cross-sectional study is to investigate the association between active smoking and thyroid disease and HS, as well as to determine if these associations are related to HS severity. METHODS: Eligible were all patients seen in our HS outpatient clinic between September 2018 and February 2020. Data regarding demographic characteristics, clinical disease severity, comorbidities, and treatment modalities were registered. Descriptive statistics of demographic and disease characteristics was conducted. In order to evaluate the association between the disease stage and certain variables of interest, ordered logistic regression was performed. RESULTS: A total of 290 patients were included in the study. Of these, 48.9% were males, and 51.1% females. The patients had a mean age of 37.3 years. A total of 42.4% of the patients were at Hurley stage I, 43.1% at stage II, and 14.5% at stage III. According to the IHS4 score system, 30.7% of the patients had mild, 50.3% moderate, and 19.0% severe disease. The median duration of disease was 10 years. Among the patients, 56.5% were active smokers, and 55.5% patients reported that stress triggers the disease's flares. Univariable analyses demonstrated that among the various covariates, active smoking and thyroid disease were associated with a higher stage of disease. CONCLUSION: We conclude that thyroid disease and active smoking may be associated with more severe HS.

Secukinumab shows significant efficacy in two patients with difficult-to-treat areas of psoriasis: a Greek experience.

Psoriasis is one of the most frequently occurring chronic inflammatory skin diseases. There are some specialized regions of the body that are considered difficult to treat. Secukinumab is a human monoclonal immunoglobulin G antibody that blocks the interleukin 17A ligand and has been shown to be highly efficacious in treating moderate-to-severe psoriasis. We studied two Greek patients, one with scalp psoriasis and the other with palmoplantar psoriasis, both resistant to treatment. Patients were treated with secukinumab and efficacy and safety were recorded. The patient with severe, refractory palmoplantar psoriasis achieved complete clearance at the end of the 4-week treatment period with secukinumab. The patient with moderate to severe, chronic scalp psoriasis was successfully treated with secukinumab, obtaining complete clearance of symptoms and remission of disease after approximately 16 weeks. In both cases clinical response was maintained through week 52. Secukinumab has been shown to be highly efficacious in the treatment of psoriasis of specific anatomical sites with an acceptable safety profile.

Perception and Knowledge of Hidradenitis Suppurativa in Greece: A Cross-Sectional Study of 1301 Individuals.

Background: Hidradenitis suppurutiva (HS) is a chronic auto-inflammatory disease with recurrent painful deep-seated nodules. Aims: The aim of this study was to qualitatively assess patients' perception for HS. Methods: A descriptive two-step questionnaire survey was conducted from January 2017 to December 2018. The survey was performed through self-assessed, online, standardized questionnaires. Clinico-epidemiological characteristics, medical history, comorbidities, personal perceptions and the impact of the disease on participants' professional and everyday life were recorded. Results: A total number of 1301 Greek people completed the questionnaire. Of them, 676 (52%) reported symptoms resembling HS, whereas 206 (16%) reported that have been officially diagnosed with HS. The mean age of the study group was 39.2 ± 11.3 years. More than half of the diagnosed patients (n = 110, 53.3%) reported that they developed their first symptoms between 12 and 25 years of age. Of the diagnosed patients (n = 206), the majority (n = 140, 68.0%) were females and active smokers (n = 124, 60.1%). Seventy-nine (n = 79, 38.3%) patients reported a positive family history for HS. Ninety-nine (n = 99, 48.1%) patients reported that HS has a negative effect on their social life, 95 (46.1%) on personal life, 115 (55.8%) on sexual life, 163 (79.1%) on their mental health and 128 (62.1%) on their overall quality of life. Conclusion: Our study showed that HS seems to be an underteated, time-consuming and cost-intensive disease.

Colchicine Improves Clinical Outcomes and Quality of Life in Hidradenitis Suppurativa Patients: A Retrospective Study.

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder of the follicular epithelium. The aim of the study was to investigate the effectiveness of colchicine on the clinical outcomes of HS patients, and to evaluate wither colchicine as monotherapy or in combination with doxycycline would provide better outcomes. Methods: A retrospective study was conducted including 44 patients with established HS, divided into three groups. The first group (n = 15 patients) received colchicine as monotherapy, the second group (n = 14 patients) received colchicine and doxycycline 100 mg/d, while the third group (n = 15 patients) received colchicine and doxycycline 40 mg/d. Disease severity during treatment was assessed at baseline and follow-up, using the Hurley Scoring System and the International Hidradenitis Suppurativa Severity Score System (IHS4). All patients were also asked to complete a Dermatology Life Quality Index (DLQI) questionnaire. These scores were compared among the study groups. Results: The DLQI and IHS4 scores significantly improved after treatment with colchicine (p < 0.001) in all groups. All colchicine regimes, including the single colchicine regime, colchicine plus doxycycline 100 mg regime, and colchicine plus doxycycline 40 mg regime, resulted in significant improvements in the DLQI and IHS4 scores (p < 0.001). Clinical improvement based on DLQI and IHS4 scores was similar in all groups. None of the patients had to discontinue the treatment due to adverse events. Discussion: In conclusion, our findings suggest that colchicine may improve clinical severity and quality of life in HS patients, either as monotherapy or in combination with doxycycline, both at antimicrobial (100 mg) and sub-antimicrobial (40 mg) doses.

Development of a three-dimensional surface imaging system for melanocytic skin lesion evaluation.

Even though surface morphology is always taken into account when assessing clinically pigmented skin lesions, it is not captured by most modern imaging systems using digital imaging. Our aim is to develop a novel three-dimensional (3D) imaging technique to record detailed information of the surface anatomy of melanocytic lesions that will enable improved classification through digital imaging. The apparatus consists of three high-resolution cameras, a light source, and accompanying software. Volume measurements of specific phantoms using volumetric tubes render slightly lower values than those obtained by our 3D imaging system (mean%± SD, 3.8%± 0.98, P<0.05). To examine the reproducibility of the method, sequential imaging of melanocytic lesions is carried out. The mean%± SD differences of area, major axis length, volume, and maximum height are 2.1%± 1.1, 0.9%± 0.8, 3.8%± 2.9, and 2.5%± 3.5, respectively. Thirty melanocytic lesions are assessed, including common and dysplastic nevi and melanomas. There is a significant difference between nevi and melanomas in terms of variance in height and boundary asymmetry (P<0.001). Moreover, dysplastic nevi have significantly higher variances in pigment density values than common nevi (P<0.001). Preliminary data suggest that our instrument has great potential in the evaluation of the melanocytic lesions. However, these findings should be confirmed in larger-scale studies.
