DETERMINANT FACTORS OF DISEASE SEVERITY FOR PATIENTS WITH HIDRADENITIS SUPPURATIVA EVALUATED IN A SPANISH HOSPITAL OVER A 5-YEAR PERIOD.

It is necessary to identify which factors or comorbidities are associated with more severe hidradenitis suppurativa, aiming to identify which patients may benefit more from early systemic treatment or a more aggressive approach. A retrospective study was conducted, including patients diagnosed with HS at the dermatology department of a Spanish hospital over a 5-year period. A total of 322 patients were included. A relationship was found between diagnostic delay, the presence of acne conglobata, pilonidal sinus, cardiovascular risk factors (hypertension, dyslipidemia, and/or diabetes mellitus) and more severe HS. No significant relationship was found between psychiatric comorbidities and the severity of the HS. The presence of perianal or truncal involvement was significantly associated with severe HS. Female sex and the presence of a family history of HS were associated with an earlier onset of the disease.

Topical and Intralesional Therapies for Hidradenitis Suppurativa: A Systematic Literature Review. / [Artículo traducido] Tratamientos tópicos e intralesionales en hidradenitis supurativa. Una revisión sistemática de la literatura.

BACKGROUND AND OBJECTIVE: Topical and intralesional (IL) treatments may be considered the first-line therapy in patients with hidradenitis suppurativa (HS); however, the evidence supporting their use is limited. The aim of our review is to evaluate the efficacy and safety profile of topical and IL treatments in patients with HS. MATERIALS AND METHODS: We designed a systematic review of the current medical literature available following the PICO(T) method. And including all types of studies (Study type [T]) of individuals with HS of any sex, age, and ethnicity (Population [P]) who received any topical or IL treatment for HS (Intervention [I]) compared to placebo, other treatments, or no treatment at all (Comparator [C]), and reported efficacy and/or safety outcomes (Outcomes [O]). Two outcomes were defined: quality of life and the no. of patients with, at least, one adverse event. The search was conducted in the Cochrane Library, MEDLINE, and Embase databases; study selection was performed based on pre-defined criteria. The risk of bias was determined in each study. RESULTS: We obtained a total of 11,363 references, 31 of which met the inclusion criteria. These studies included 1143 patients with HS, 62% of whom were women. A total of 10, 8, 6, 2, and 5 studies, respectively, evaluated the use of photodynamic therapy (PDT), glucocorticoids, resorcinol, topical antibiotics, and other interventions. Most articles were case series (n=25), with only five randomized clinical trials (RCTs) and one cohort study. RCTs showed improvement in disease activity with topical clindamycin and botulinum toxin (BTX) vs placebo, and PDT with methylene blue (MB) niosomal vs free MB; however, intralesional triamcinolone acetonide was not superior to placebo. The risk of bias was low in three RCTs and high in two RCTs. CONCLUSION: The quality of evidence supporting the use of topical, or IL treatments is low. However, it supports the use of topical clindamycin, PDT, and BTX. Well-designed RCTs with standardized outcomes and homogeneous populations of patients and lesions are needed to support decision-making in the routine clinical practice.

Liraglutide for the treatment of obesity among patients with hidradenitis suppurativaLiraglutida en el tratamiento de la obesidad en pacientes con hidradenitis supurativa / Liraglutide for the treatment of obesity among patients with hidradenitis suppurativa Liraglutida en el tratamiento de la obesidad en pacientes con hidradenitis supurativa

Background and aims: Hidradenitis suppurativa (HS) is associated with obesity. Weight loss is frequently reflected in an amelioration in the severity of the lesions. Case reports have suggested that liraglutide might improve not only weight but also skin. We aimed to study the effects of liraglutide 3mg in patients with obesity and HS on metabolic and dermatological parameters. Methods: 14 patients started treatment with liraglutide for 3 months. Severity of the lesions was evaluated using the Hurley Staging System and quality of life with the DLQI (Dermatology Quality Index). Results: There was a significant reduction in BMI (39.3±6.2 vs 35.6±5.8; p=0.002), waist circumference (121.3±19.2 vs 110.6±18.1cm; p=0.01), CRP (4.5±2.2 vs 3±2.1mg/L; p=0.04), homocysteine (16.2±2.9 vs 13.3±3μmol/L; p=0.005) and plasma cortisol (15.9±4.8 vs 12.6±4.5μg/dL; p=0.007). Hurley (2.6±0.5 vs 1.1±0.3; p=0.002) and DLQI (12.3±2.8 vs 9.7±6.9; p=0.04) improved significantly. In multiple regression analysis, weight loss did not correlate with any inflammatory parameter or Hurley. Conclusions: Liraglutide 3mg is effective and safe among patients with HS and obesity. Long-term studies are mandatory to assess the effects of liraglutide on skin lesions and inflammatory markers among subjects with HS beyond weight loss.(AU)

Antecedentes y objetivos: La hidradenitis supurativa (HS) se asocia a la obesidad. La pérdida de peso frecuentemente comporta una mejora en la gravedad de las lesiones. Casos aislados han sugerido que la liraglutida podría mejorar no solo el peso sino también la piel. Nuestro objetivo fue estudiar los efectos de liraglutida 3mg en pacientes con obesidad y HS sobre los parámetros metabólicos y dermatológicos. Métodos: Catorce pacientes iniciaron tratamiento con liraglutida durante 3meses. La gravedad de las lesiones se evaluó mediante la Escala de Hurley y la calidad de vida con el Dermatology Quality Index (DLQI). Resultados: Hubo una reducción significativa en el IMC (39,3±6,2 vs 35,6±5,8; p=0,002), la circunferencia de cintura (121,3±19,2 vs 110,6±18,1cm; p=0,01), la PCR (4,5±2,2 vs 3±2,1mg/l; p=0,04), la homocisteína (16,2±2,9 vs 13,3±3μmol/l; p=0,005) y el cortisol plasmático (15,9±4,8 vs 12,6±4,5μg/dl; p=0,007). El Hurley (2,6±0,5 vs 1,1±0,3; p=0,002) y la DLQI (12,3±2,8 vs 9,7±6,9; p=0,04) mejoraron significativamente. En el análisis de regresión múltiple, la pérdida de peso no se correlacionó con ningún parámetro inflamatorio ni con el Hurley. Conclusiones: Liraglutida 3mg es eficaz y segura en pacientes con HS y obesidad. Serán necesarios estudios a largo plazo para evaluar los efectos de la liraglutida sobre las lesiones cutáneas y los marcadores inflamatorios en la HS más allá de la pérdida de peso.(AU)

Gluteal Hidradenitis Suppurativa: Analysis of 83 Patients / Hidradenitis supurativa con afectación glútea: análisis de 83 pacientes

Background In 2013, Canoui-Poitrine et al. identified three hidradenitis suppurativa (HS) phenotypes by a latent class (LC) analysis, based on anatomical sites of involvement. Objective To improve the classification of the gluteal phenotype (LC3) patients given their diverse lesion types and differences in clinical profile. Material and methods We designed a bicentric study gathering all LC3 patients (n=83) from two hospitals. We conducted a two-step cluster analysis among them and also compared their characteristics with the rest of the HS patients (n=661). Results Compared with global HS series, LC3 patients were more frequently non-obese men, with smoking habit, an associated arthropathy, and a more frequent history of pilonidal sinus. The analysis of LC3 patients yielded two clusters: cluster 1 (38.3%) included elderly female patients, with later diagnosis of the disease and more sinus tracts; cluster 2 (61.7%) encompassed more men with earlier disease onset and more nodules and folliculitis lesions. Limitations The study's limitations include its retrospective nature, bicentric design, and small sample size. Conclusion The heterogeneous clinical presentation of HS makes it essential to have a good classification of the patients. Gluteal phenotype could actually be classified into two “subphenotypes” with a different clinical profiles and management (AU)

Antecedentes En 2013 Canoui-Poitrine et al. identificaron tres fenotipos de hidradenitis supurativa (HS) mediante un análisis de clases latentes (LC) basado en las regiones anatómicas afectadas. Objetivo Mejorar la clasificación de los pacientes con fenotipo glúteo (LC3) dados los diversos tipos de lesiones y diferencias en el perfil clínico. Material y métodos Diseñamos un estudio bicéntrico que incluyó a todos los pacientes con LC3 (n=83) de dos hospitales terciarios españoles. Realizamos un análisis de conglomerados en dos etapas dentro del grupo LC3 y también comparamos sus características con el resto de los pacientes con HS (n=661). Resultados En comparación con la serie global de HS, los pacientes con LC3 fueron más frecuentemente hombres no obesos, fumadores, con una artritis asociada y con mayor prevalencia de sinus pilonidal. El análisis de los pacientes LC3 resultó en dos grupos: el grupo 1 (38,3%), que incluía pacientes mayores, de sexo femenino, con diagnóstico más tardío de la enfermedad y más trayectos sinusales; y el grupo 2 (61,7%), que englobaba a más hombres con inicio temprano de la enfermedad y más nódulos y lesiones de foliculitis. Limitaciones Las limitaciones del estudio incluyen su naturaleza retrospectiva, el diseño bicéntrico y el tamaño muestral reducido. Conclusión La presentación clínica heterogénea de la HS hace que sea esencial disponer de una buena clasificación clínica de los pacientes. Como hemos visto, parece que el fenotipo glúteo podría clasificarse en dos «subfenotipos» con perfiles clínicos y, consecuentemente, enfoques terapéuticos diferentes (AU)

Hidradenitis supurativa / Hidradenitis suppurativa

La hidradenitis supurativa (HS) es una enfermedad inflamatoria crónica y recurrente derivada de la unidad pilosebácea, que afecta aproximadamente al 1% de la población general. Se caracteriza clínicamente por nódulos inflamatorios, abscesos y túneles en las áreas intertriginosas del cuerpo, especialmente en las regiones axilar, inguinal y anogenital. La etiopatogenia de la HS no está totalmente aclarada, aunque se considera que es multifactorial, y resultado de una compleja interacción entre factores genéticos, hormonales, ambientales e inmunológicos. En este sentido, determinadas citocinas proinflamatorias como el factor de necrosis tumoral-alfa (TNF-α), la interleucina (IL)-1β y la IL-17, entre otras, parecen desempeñar un papel fundamental en la patogénesis de la enfermedad. Actualmente, la HS es considerada una enfermedad inflamatoria sistémica asociada con numerosas comorbilidades, incluyendo enfermedades cardiovasculares, inmunomediadas y trastornos endocrino-metabolicos. El tratamiento de la HS debe realizarse con un enfoque individualizado y orientado al paciente, considerando modalidades de tratamiento médico y quirúrgico.(AU)

Hidradenitis suppurativa (HS) is a chronic and debilitating inflammatory disease derived from the pilosebaceous unit, that affects approximately 1% of the general population. Clinically, it is characterized by inflammatory nodules, abscesses, and tunnels in the intertriginous areas of the body, especially in the axillary, inguinal, and anogenital regions. The etiopathogenesis of HS is not completely understood, although it is considered to be multifactorial, and the result of a complex interaction between genetic, hormonal, environmental, and immunological factors. In this sense, several proinflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α), interleukin (IL)-L-1β, and IL-17, among others, appear to play a crucial role in the pathogenesis of the disease. Currently, HS is recognized as a systemic disease associated with numerous comorbidities, including cardiovascular, immune-mediated, and endocrine-metabolic diseases. The treatment of HS must be carried out with an individualized and patient-oriented approach, considering medical and surgical treatment modalities.(AU)

[Translated article] Glucagon-Like Peptide-1 Agonists for Treating Obesity in Patients With Immune-Mediated Skin Diseases / Agonistas del receptor de GLP-1 para el tratamiento de la obesidad en pacientes con dermatosis inmunomediadas

Psoriasis and hidradenitis suppurativa are often associated with obesity. Because chronic low-grade inflammation underlies these 2 diseases, they can progress to more severe forms in patients with obesity if weight-reduction measures are not taken. This review covers pharmacologic alternatives for treating obesity, with emphasis on the benefits associated with the novel use of glucagon-like peptide-1 (GLP-1) agonists that act on satiety receptors. These drugs have led to greater weight loss in clinical trials and real-world settings than orlistat, which until recently was the only drug approved for treating obesity in the European Union. Although experience with GLP-1 agonists in patients with obesity and inflammatory skin diseases is currently scarce, the promising results reported suggest they may offer a useful tool for managing obesity (AU)

La psoriasis (PsO) y la hidradenitis supurativa (HS) se asocian frecuentemente con la obesidad. La inflamación crónica de bajo grado subyace a estas condiciones, por lo que si no se adoptan medidas para reducir el peso del paciente con obesidad y PsO o HS, estas podrían evolucionar hacia formas más graves. Este trabajo revisa las opciones farmacológicas para tratar la obesidad, profundizando en los beneficios asociados al uso novedoso de agonistas del receptor de GLP-1 (arGLP-1), que actúan sobre los centros de la saciedad. Los resultados de ensayos y vida real demuestran que esta medicación consigue mayores pérdidas de peso que orlistat, hasta recientemente el único fármaco específico para la obesidad comercializado en la Unión Europea. Aunque la experiencia con arGLP-1 en pacientes con obesidad y dermatosis inflamatorias es escasa, los resultados son alentadores, por lo que podrían constituir una herramienta útil para el manejo de su obesidad (AU)

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects the apocrine sweat glands and causes inflammatory nodules, abscesses, and painful fistulas in areas such as the armpits, groin, and buttocks. Its impact on patients' quality of life is significant. HS affects 1-4% of the world's population and is associated with factors such as overweight, smoking, and family history. Its pathogenesis is complex, involving inflammation and immune dysfunction. Its diagnosis and treatment are challenging, especially in severe cases. Diagnosis is based on clinical presentation, which is often confused with other skin conditions. It is classified into Hurley stages based on severity. Treatment focuses on controlling symptoms and preventing recurrences. Includes patient education, medical treatment and surgery. The choice of antibiotic therapy depends on the severity and the bacterial strains present. For severe cases, biological therapies are investigated. Surgery, such as simple excision or skin grafts, is effective in controlling the disease. We present a clinical case of a patient with HS, we review the epidemiology, etiopathogenesis and its diagnosis accompanied by the existing therapeutic options.

Topical and Intralesional Therapies for Hidradenitis Suppurativa: A Systematic Literature Review.

BACKGROUND AND OBJECTIVE: Topical and intralesional (IL) treatments may be considered the first-line therapy in patients with hidradenitis suppurativa (HS); however, the evidence supporting their use is limited. The aim of our review is to evaluate the efficacy and safety profile of topical and IL treatments in patients with HS. MATERIALS AND METHODS: We designed a systematic review of the current medical literature available following the PICO(T) method. And including all types of studies (Study type [T]) of individuals with HS of any sex, age, and ethnicity (Population [P]) who received any topical or IL treatment for HS (Intervention [I]) compared to placebo, other treatments, or no treatment at all (Comparator [C]), and reported efficacy and/or safety outcomes (Outcomes [O]). Two outcomes were defined: quality of life and the no. of patients with, at least, one adverse event. The search was conducted in the Cochrane Library, MEDLINE, and EMBASE databases; study selection was performed based on pre-defined criteria. The risk of bias was determined in each study. RESULTS: We obtained a total of 11,363 references, 31 of which met the inclusion criteria. These studies included 1143 patients with HS, 62% of whom were women. A total of 10, 8, 6, 2, and 5 studies, respectively, evaluated the use of photodynamic therapy (PDT), glucocorticoids, resorcinol, topical antibiotics, and other interventions. Most articles were case series (n=25), with only five randomized clinical trials (RCTs) and one cohort study. RCTs showed improvement in disease activity with topical clindamycin and botulinum toxin (BTX) vs placebo, and PDT with methylene blue (MB) niosomal vs free MB; however, intralesional triamcinolone acetonide was not superior to placebo. The risk of bias was low in three RCTs and high in two RCTs. CONCLUSION: The quality of evidence supporting the use of topical, or IL treatments is low. However, it supports the use of topical clindamycin, PDT, and BTX. Well-designed RCTs with standardized outcomes and homogeneous populations of patients and lesions are needed to support decision-making in the routine clinical practice.

The Effectiveness of Guselkumab in Patients With Hidradenitis Suppurativa Under Clinical Practice Conditions: A Spanish Multicentre Retrospective Study / fectividad de guselkumab en pacientes con hidradenitis supurativa en condiciones de práctica clínica: estudio retrospectivo y multicéntrico en España

Background Hidradenitis suppurativa (HS) is a chronic skin condition causing lesions in which high levels of interleukin (IL)-23 and T-helper 17 cells are found. Adalimumab remains the only approved treatment. Guselkumab, an antibody targeting the p19 protein subunit of extracellular IL-23, is approved for the treatment of moderate–severe psoriasis, but evidence on its efficacy in treating HS is limited.Objectives To assess the effectiveness and safety of guselkumab in treating moderate–severe HS under clinical practice conditions. Methods A multicentre retrospective observational study was carried out in 13 Spanish Hospitals including adult HS patients treated with guselkumab within a compassionate use programme (March 2020–March 2022). Data referred to patient demographic and clinical characteristics at treatment initiation (baseline), patient-reported outcomes (Numerical Pain Rating Scale [NPRS] and Dermatology Life Quality Index [DLQI]), physician scores (International Hidradenitis Suppurativa Severity Score System [IHS4], HS Physical Global Score [HS-PGA] and Hidradenitis Suppurativa Clinical Response [HiSCR]) were recorded at baseline and at 16, 24, and 48 weeks of treatment. Results A total of 69 patients were included. Most (84.10%) had severe HS (Hurley III) and had been diagnosed for over ten years (58.80%). The patients had been subjected to multiple non-biological (mean 3.56) or biological (mean 1.78) therapies, and almost 90% of those treated with biologics had received adalimumab (AU)

Antecedentes La hidradenitis supurativa (HS) es una situación cutánea crónica que causa lesiones en las que se encuentran altos niveles de interleucina (IL)-23 y células TH-17 colaboradoras, siendo adalimumab el único tratamiento aprobado. Guselkumab, un anticuerpo que focaliza la subunidad de la proteína p19 de IL-23 extracelular, ha sido aprobado para tratar la psoriasis de moderada a severa, siendo limitada la evidencia sobre su eficacia en el tratamiento de la HS. Objetivos Evaluar la efectividad y seguridad de guselkumab para el tratamiento de la HS de moderada a severa, en condiciones de práctica clínica. Métodos Se llevó a cabo un estudio observacional retrospectivo y multicéntrico en 13 hospitales españoles, que incluyó pacientes adultos de HS tratados con guselkumab, dentro de un programa de uso compasivo (de marzo de 2020 a marzo de 2022). Se registraron al inicio y a las 16, 24 y 48 semanas de tratamiento los datos referentes a las características demográficas y clínicas de los pacientes, los resultados reportados por el paciente (Numerical Pain Rating Scale [NPRS] y Dermatology Life Quality Index [DLQI]), puntuaciones del facultativo (International Hidradenitis Suppurativa Severity Score System [IHS4], HS Physical Global Score [HS-PGA] e Hidradenitis Suppurativa Clinical Response [HiSCR]). Resultados Se incluyó un total de 69 pacientes, de los cuales la mayoría (84,10%) tenían HS severa (Hurley III) y habían sido diagnosticados hacía más de 10 años (58,80%). Dichos pacientes habían sido sometidos a múltiples terapias no biológicas (media 3,56) o biológicas (media 1,78), y casi el 90% de los tratados con biológicos habían recibido adalimumab. Se observó una reducción significativa de las puntuaciones IHS4, HS-PGA, NPRS y DLQI desde el inicio hasta las 48 semanas del tratamiento con guselkumab (total p<0,01). Se logró HiSCR en el 58,33% y el 56,52% de los pacientes, a las 16 y 24 semanas, respectivamente (AU)

Background Hidradenitis suppurativa (HS) is a chronic skin condition causing lesions in which high levels of interleukin (IL)-23 and T-helper 17 cells are found. Adalimumab remains the only approved treatment. Guselkumab, an antibody targeting the p19 protein subunit of extracellular IL-23, is approved for the treatment of moderate–severe psoriasis, but evidence on its efficacy in treating HS is limited.Objectives To assess the effectiveness and safety of guselkumab in treating moderate–severe HS under clinical practice conditions.

Narrative Review and Update on Biologic and Small Molecule Drugs for Hidradenitis Suppurativa: An Entity With a Promising Future / Revisión narrativa y actualización en fármacos biológicos y de pequeña molécula para el tratamiento de la hidradenitis supurativa: una entidad con un futuro prometedor

Hidradenitis suppurativa (HS) is a chronic inflammatory entity characterized by the appearance of multiple nodules, abscesses, and fistulas, predominantly in apocrine regions. In addition to its dermatological involvement, it is associated with multiple systemic comorbidities. Its treatment is combined: topical pharmacological, systemic pharmacological and surgical. Regarding biologic or small molecule drugs, currently only adalimumab is approved. A narrative review of the literature on biological or small molecule drugs used in the treatment of hidradenitis suppurativa is presented. The arsenal we found is large, with multiple targets: inhibitors of tumor necrosis factor alpha (TNF-alpha), interleukin (IL)-17, IL-23, IL-1, inhibitors of the janus kinase (JAK) pathway, and multiple other drugs in study. New prospective studies and comparative trials are needed to analyze the effectiveness and safety of these treatments, in an entity with a promising future (AU)
