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)

Comité quirúrgico para la hidradenitis supurativa: nuestra experiencia / Hidradenitis Suppurative: Our Experience with a Surgical Case Management Team

ANTECEDENTES Y OBJETIVOS: La complejidad del tratamiento de la hidradenitis supurativa (HS) hace necesario un abordaje multidisciplinar, y con este fin diseñamos un comité quirúrgico para su abordaje. Este estudio describe las características clínicas de los pacientes evaluados y los resultados de las técnicas quirúrgicas realizadas. MATERIAL Y MÉTODOS: Presentamos un estudio descriptivo transversal que recoge 104 pacientes que fueron evaluados en nuestro comité desde setiembre de 2015 hasta julio de 2018. RESULTADOS: En nuestra serie, el 46% de los pacientes con HS evaluados recibieron tratamiento quirúrgico. La mayoría fueron varones (73%), sin antecedentes familiares de HS (63%), exfumadores o fumadores (76%). El fenotipo clínico predominante fue el tipo III (41%), con presencia de patología grave en la mayor parte de los casos (36% con Hurley II y 46% con Hurley III). Las áreas anatómicas más afectadas fueron las axilas (51,9%) y las ingles (41,3%); mientras que las intervenidas con mayor frecuencia fueron la axilar (38,3%), seguida de la glútea (23,4%). Entre los tratamientos médicos, el más usado fue la combinación de rifampicina con clindamicina. El destechamiento (deroofing) se posicionó como la técnica quirúrgica más empleada entre los pacientes intervenidos (hasta en un 48%). En cuanto al resultado posquirúrgico global: un 63,4% obtuvo un resultado satisfactorio, un 20% recidivó y un 12% presentó dehiscencia de la herida quirúrgica. CONCLUSIONES: Dada nuestra experiencia, recomendamos la instauración de comités multidisciplinares para mejorar la comunicación entre los diferentes especialistas, así como individualizar el tratamiento y mejorar el seguimiento de los pacientes con HS

BACKGROUND AND OBJECTIVES: The complexity of hidradenitis suppurativa (HS) treatment calls for a multidisciplinary approach. We therefore created a multidisciplinary team to manage surgical care. This study aimed to describe the clinical characteristics of the patients we evaluated and the outcomes of the surgical techniques used. MATERIAL AND METHODS: Descriptive cross-sectional study of 104 patients evaluated by our surgical case management team between September 2015 and July 2018. RESULTS: Surgery was used to treat 46% of the patients with HS who were evaluated. Most were men (73%) with no family history of HS (63%) and smokers or former smokers (76%). Gluteal HS comprised the largest phenotype group (41%) and the majority of cases were serious (Hurley stage II, 36%; stage III, 46%). The anatomical regions with the largest number of lesions were the axillae (51.9%) and the groin (41.3%). Surgery was most often performed in the axilla (38.3%), followed by the gluteus (23.4%). The most common drug treatment was a combination of rifampicin and clindamycin, Deroofing was the technique used most often (in 48% of the patients who underwent surgery). Postoperative outcomes were assessed as satisfactory overall in 63.4% of the cases. The HS lesion recurred in 20% and 12% developed wound dehiscence. CONCLUSIONS: Our experience leads us to recommend forming multidisciplinary teams to improve communication between specialists, provide tailored treatment for the patient with HS, and improve follow-up
