El resurgir del linfogranuloma venéreo, una enfermedad que el dermatólogo debería conocer / Resurgence of Lymphogranuloma Venereum: A Disease Dermatologists Need to Know About

El linfogranuloma venéreo (LGV) es una infección de transmisión sexual (ITS) producida por los serovares L1, L2 y L3 de la bacteria Chlamydia trachomatis y cuya incidencia está en aumento. Presentamos una serie de 8 pacientes diagnosticados en nuestra unidad de ITS del servicio de dermatología. La edad de nuestros pacientes es menor que en otras series publicadas y el síntoma más frecuente de presentación es la tumoración adenopática inguinal. El dermatólogo debe conocer esta enfermedad y realizar una correcta toma de muestras para un diagnóstico preciso y un tratamiento precoz (AU)

The incidence of lymphogranuloma venereum (LGV) —a sexually transmitted infection (STI) produced by the L1, L2, and L3 serovars of Chlamydia trachomatis— is increasing. The 8 patients in this case series were diagnosed with LGV in the STI unit of our dermatology department. Our patients were younger than those in previously published case series, and on presentation they most often complained of tumorous masses (lymphadenopathy) in the groin. Dermatologists should be familiar with this disease. Samples must be taken correctly to ensure an accurate diagnosis and early treatment (AU)

Response of pruritic scrotal epidermolytic acanthomas to pimecrolimus 1% cream.

Epidermolytic acanthomas (EA) are rare benign tumors of unclear etiology that present as flat, sometimes slightly keratotic, pale or whitish papules that are usually asymptomatic. Not uncommonly, their clinical appearance in the anogenital area might lead to misdiagnosis as other lesions that commonly develop at this site, such as condylomata acuminata. Though mainly asymptomatic, there are also reports of EA presenting with persistent genital pruritus. We describe the first reported case of pruritic scrotal EA successfully treated with topical pimecrolimus.

Asociación entre penfigoide ampolloso e inhibidores de la dipeptidilpeptidasa-4: estudio de cohortes retrospectivo / Association Between Bullous Pemphigoid and Dipeptidyl Peptidase 4 Inhibitors: A Retrospective Cohort Study

ANTECEDENTES: La asociación entre los inhibidores de la dipeptidil peptidasa 4 (iDPP-4) y el penfigoide ampolloso (PA) se ha demostrado en varios estudios. El objetivo principal de este estudio era estimar el uso del tratamiento con iDPP-4i en pacientes diagnosticados de PA en nuestro entorno. MATERIAL Y MÉTODOS: Seleccionamos pacientes diagnosticados histológicamente de PA en nuestro departamento entre octubre de 2015 y octubre de 2018. Realizamos una revisión retrospectiva para evaluar los datos clínicos-epidemiológicos y los patrones de inmunofluorescencia directa (IFD). RESULTADOS: De los 70 pacientes diagnosticados con PA durante el período de estudio, el 50% eran diabéticos y el 88,57% de ellos estaban siendo tratados con un iDPP-4 en el momento del diagnóstico de PA. El iDPP-4 más frecuente era la linagliptina (utilizada en el 18,6% de los pacientes), seguida de la vildagliptina (el 17,1%). La mediana de tiempo de latencia entre el inicio del tratamiento con iDPP-4 y el diagnóstico de PA fue de 27,5 meses, siendo de 16 meses para la linagliptina y 39 meses para la vildagliptina (log Rank < 0,01). La IFD fue negativaUn resultado negativo de DIF fue significativamente más común en pacientes que no fueron tratados con un DPP-4i. El patrón DIF más fuertemente (y significativamente) asociado con el tratamiento con DPP-4i fueron los depósitos lineales de inmunoglobulina G a lo largo de la unión dermoepidérmica. El tratamiento con DPP-4i se retiró en el 87% de los pacientes y el 96% de ellos logró una respuesta completa. CONCLUSIÓN: El tratamiento con DPP-4i es muy común en pacientes con BP en nuestro entorno. El período de latencia entre el inicio del tratamiento y el inicio de la PA parece ser más corto con linagliptina que con otros tipos de gliptinas. Los pacientes que reciben tratamiento con DPP-4i pueden mostrar patrones DIF diferentes a los que no reciben tratamiento

BACKGROUND: The association between dipeptidyl peptidase 4 inhibitors (DPP-4i) and bullous pemphigoid (BP) has been demonstrated in several studies. The main aim of this study was to estimate the use of DPP-4i treatment in patients diagnosed with BP in our setting. METHODS: We selected patients histologically diagnosed with BP in our department between October 2015 and October 2018 and performed a retrospective chart review to assess clinical and epidemiological data and direct immunofluorescence (DIF) patterns. RESULTS: Of the 70 patients diagnosed with BP during the study period, 50% were diabetic and 88.57% of these were being treated with a DPP-4i when diagnosed with BP. The most common DPP-4i was linagliptin (used in 18.6% of patients), followed by vildagliptin (17.1%). The median latency period between initiation of DPP-4i treatment and diagnosis of BP was 27.5 months for all treatments, 16 months for linagliptin, and 39 months for vildagliptin (log rank < 0.01). A negative DIF result was significantly more common in patients not being treated with a DPP-4i. The DIF pattern most strongly (and significantly) associated with DPP-4i treatment was linear immunoglobulin G deposits along the dermal-epidermal junction. DPP-4i treatment was withdrawn in 87% of patients and 96% of these achieved a complete response. CONCLUSIONS: DPP-4i treatment is very common in patients with BP in our setting. The latency period between start of treatment and onset of BP seems to be shorter with linagliptin than with other types of gliptins. Patients receiving DPP-4i treatment may show different DIF patterns to those not receiving treatment

Experiencia en el uso de fototerapia en pacientes pediátricos y comparación de esta técnica frente a pacientes adultos / Comparison of Phototherapy in Pediatric and Adult Patients

INTRODUCCIÓN: La fototerapia se basa en el uso de radiación ultravioleta para el tratamiento de distintas enfermedades dermatológicas. Su eficacia y seguridad está ampliamente establecida en adultos y existen publicaciones que también lo avalan como un tratamiento efectivo y seguro en pacientes pediátricos con afecciones cutáneas recalcitrantes. MATERIAL Y MÉTODOS: Estudio retrospectivo desde 2002 hasta 2017 que incluye a todos los pacientes menores de 17 años que recibieron fototerapia en nuestro servicio. Además, se seleccionaron al azar 122 pacientes adultos que recibieron este tratamiento durante el mismo periodo de tiempo. RESULTADOS: Se realizaron un total de 98 tratamientos pediátricos, 61% en niñas y 39% en niños, con una media de edad de 10,5 años. Las 3 enfermedades más frecuentemente tratadas fueron la psoriasis (48% de pacientes), el vitíligo (17%) y la dermatitis atópica (16%). El 86% de los pacientes recibió fototerapia con radiación ultravioleta B de banda estrecha (UVB-BE), mientras que el 7% recibió fototerapia con radiación ultravioleta A con psoralenos (PUVA). No existían diferencias estadísticamente significativas en cuanto a dosis, duración o número de sesiones con respecto a la población adulta tratada con UVB-BE ni con PUVA. Se alcanzó una respuesta completa en el 35% de los pacientes pediátricos, sin diferencias con respecto a los adultos. Únicamente el 16% de los pacientes mostró efectos adversos, en su mayoría en forma de eritema leve. Encontramos mayor adherencia al tratamiento en los pacientes pediátricos que en los adultos (p < 0,05). CONCLUSIONES: La fototerapia con UVB-BE y/o PUVA parece un tratamiento seguro y eficaz en niños, sin ser necesarios protocolos de tratamiento diferentes a los empleados en adultos. La adherencia al tratamiento es mayor que en los pacientes adultos

INTRODUCTION: Phototherapy involves the use of UV radiation to treat different dermatologic diseases. Its efficacy and safety have been thoroughly established in adults and some publications indicate that it is also an effective and safe treatment in pediatric patients with refractory skin diseases. MATERIAL AND METHODS: Retrospective study that included all patients under 17 years of age and 122 randomly selected adults who received phototherapy in our department between 2002 and 2017. RESULTS: Ninety-eight pediatric patients (61% girls and 39% boys) with a mean age of 10.5 years received phototherapy. The 3 most frequently treated diseases were psoriasis (48% of patients), vitiligo (17%), and atopic dermatitis (16%). Eighty-six percent of the patients received phototherapy with narrowband UV-B, whereas 7% received phototherapy with psoralen and UV-A (PUVA). No statistically significant differences were found in terms of dosage, duration, or number of sessions compared to the adult population treated with narrowband UV-B therapy or PUVA. A complete response was achieved in 35% of the pediatric patients and no differences were found with respect to the adults. Only 16% of the children showed adverse effects, mostly in the form of mild erythema. We found greater adherence to treatment in the pediatric patients than in the adult patients (P < .05). CONCLUSIONS: Narrowband UV-B therapy and PUVA appear to be safe and effective in children and can be administered using the same treatment protocols as those used in adults. Adherence to treatment is greater in children than in adult patients

Infecciones genitales por virus herpes tipo 1 y virus herpes tipo 2 en Valencia, España: estudio observacional retrospectivo / Genital Infection With Herpes Simplex Virus Type 1 and Type 2 in Valencia, Spain: A Retrospective Observational Study

INTRODUCCIÓN Y OBJETIVO: Se ha constatado un cambio en la epidemiología del herpes genital en los últimos años con un aumento de la incidencia del virus herpes (VHS) tipo 1. El objetivo de nuestro estudio es analizar las características clínico-epidemiológicas de los pacientes diagnosticados de un herpes genital. MATERIAL Y MÉTODOS: Se diseñó un estudio observacional retrospectivo donde se incluyeron todos los pacientes diagnosticados de herpes genital entre enero de 2016 y enero de 2019 en una Unidad de Infecciones de Transmisión Sexual (ITS) en Valencia, España. RESULTADOS: Se diagnosticaron 895 ITS, de las cuales 126 fueron un herpes genital (14%), 68 (54%) en mujeres y 58 (46%) en hombres. En 110 de ellos (87,3%) se confirmó el herpes genital por la detección de ADN viral por técnicas moleculares. Se diagnosticaron 52 casos de VHS tipo 1 (47,3%) y 58 casos de VHS tipo 2 (52,7%). En el 69,5% de los hombres se detectó el VHS tipo 2, mientras que en el 59,3% de las mujeres se detectó el VHS tipo 1. La edad media de las mujeres diagnosticadas de VHS tipo 1 fue de 26 años, mientras que la de las mujeres diagnosticadas de VHS tipo 2 fue de 34 años (p = 0,015). Las recurrencias de las lesiones en los pacientes con VHS tipo 1 y VHS tipo 2 fue del 13% y del 40%, respectivamente. CONCLUSIÓN: Destacamos un aumento de la prevalencia del VHS tipo 1 en nuestro medio como agente causante de herpes genital, especialmente en mujeres jóvenes. Esto tiene un valor pronóstico importante dado el menor riesgo de recurrencias que tiene

INTRODUCTION AND OBJECTIVE: The epidemiology of genital herpes has changed in recent years with an increase in the incidence of herpes simplex virus type 1 (HSV-1) infection. The aim of this study was to analyze the clinical and epidemiological characteristics of patients diagnosed with genital herpes. MATERIAL AND METHODS: A retrospective observational study was designed. All patients diagnosed with genital herpes between January 2016 and January 2019 in a Sexually Transmitted Infections Unit (ITS) in Valencia, Spain, were included. RESULTS: We identified 895 STI diagnoses. Of these, 126 (14%) were genital herpes; 68 (54%) of these cases were in women and 58 (46%) in men. Diagnosis was confirmed by molecular detection of HSV DNA in 110 cases (87.3%). Of these, 52 were cases of HSV-1 infection (47.3%) and 58 were HSV-2 infection (52.7%). HSV-2 was more common in men (69.5%), while HSV-1 was more common in women (59.3%). In the subgroup of women, mean age at diagnosis was 26 years for HSV-1 and 34 years for HSV-2 (P = .015). Recurrent genital herpes rates were 13% for HSV-1 and 40% for HSV-2. CONCLUSIONS: There has been an increase in the number of cases of genital herpes caused by HSV-1 in our setting, with young women in particular being affected. This has important prognostic implications because genital herpes caused by HSV-1 is less likely to recur

The median latency period between initiation of DPP-4i treatment and diagnosis of BP was 27.5 months for all treatments, 16 months for linagliptin, and 39 months for vildagliptin (log rank < 0.01). A negative DIF result was significantly more common in patients not being treated with a DPP-4i. The DIF pattern most strongly (and significantly) associated with DPP-4i treatment was linear immunoglobulin G deposits along the dermal-epidermal junction. DPP-4i treatment was withdrawn in 87% of patients and 96% of these achieved a complete response. CONCLUSIONS: DPP-4i treatment is very common in patients with BP in our setting. The latency period between start of treatment and onset of BP seems to be shorter with linagliptin than with other types of gliptins. Patients receiving DPP-4i treatment may show different DIF patterns to those not receiving treatment.

Introducción: Ixekizumab es un fármaco efectivo y seguro en el tratamiento de pacientes con psoriasis dentro de ensayos clínicos. Nuestro objetivo es valorar la eficacia y seguridad de ixekizumab en la práctica clínica habitual. Material: Estudio retrospectivo incluyendo todos los pacientes que han recibido ixekizumab en 2 servicios de dermatología de la ciudad de Valencia. Resultados: Se incluyeron un total de 75 pacientes, siendo el 53,3% varones y el 46,7% mujeres con una edad media de 48,61 años. El 77,3% (58 pacientes) presentaba una psoriasis en placas, mientras que el 22,7% (17 pacientes) presentaba psoriasis de predominio en un área especial. La comorbilidad más frecuente fue obesidad en el 48% de ellos y el 40% eran naive a biológicos. El PASI inicial medio fue de 9,99, mientras que el PASI medio a la semana 16 era de 1,5. Las respuestas de PASI75 y PASI90 fueron independientes de las comorbilidades analizadas, del sexo, de la edad y del PASI basal. Los pacientes naive a biológicos respondieron mejor que los pacientes que habían recibido tratamiento biológico previo, tanto en la semana 16 como en la semana 52 de forma estadísticamente significativa. Esta observación también se mantuveroni en los pacientes con psoriasis en un área especial. El 25,7% de los pacientes refería algún efecto adverso, siendo lo más frecuente reacción en el sitio de inyección. No se observaron reacciones adversas graves. Conclusiones: El estudio plasma nuestra experiencia en la práctica clínica real de ixekizumab, siendo un fármaco efectivo y seguro para el tratamiento de la psoriasis

Background: Ixekizumab has proven efficacy and safety for the treatment of psoriasis in clinical trials. The aim of this study was to evaluate its effectiveness and safety in routine clinical practice. Methods: Retrospective study of all patients treated with ixekizumab in 2 dermatology departments in the city of Valencia, Spain. Results: Seventy-five patients (53.3% men and 46.7% women) with a mean age of 48.61 years were studied; 77.3% (n = 58) had plaque psoriasis and 22.7% (n = 17) had psoriasis predominantly affecting a specific area. The most common comorbidity was obesity (present in 48% of patients) and 40% of the overall group had not been previously treated with a biologic drug. Mean psoriasis area and severity index (PASI) fell from 9.99 at baseline to 1.5 at week 16. PASI-75 and PASI-90 (improvements of at least 75% and 90% in PASI) were independent of sex, age, baseline PASI, and the comorbidities analyzed. Responses at week 16 and 52 were significantly better in biologic-naïve patients for the overall group and the subgroup of patients with localized psoriasis. Adverse effects were reported for 25.7% of patients and the most common effect was injection-site reaction. There were no serious adverse effects. Conclusions: Our findings show that ixekizumab is both effective and safe in the treatment of psoriasis in routine clinical practice
