Ustekinumab Drug Survival in Patients with Psoriasis: A retrospective Study of Real Clinical Practice.

Background and objectives: The efficacy and safety of ustekinumab have been proved in clinical trials. In daily clinical practice, knowing the factors that determine survival differences of biological drugs allows psoriasis treatment to be optimized as a function of patient characteristics. The main objectives of this work are to understand ustekinumab drug survival in patients diagnosed with plaque psoriasis in the Hospital Universitario Central de Asturias (HUCA Dermatology Department, and to identify the predictors of drug discontinuation. Materials and Methods: A retrospective hospital-based study, including data from 148 patients who were receiving ustekinumab (Stelara®) between 1 February 2009 and 30 November 2019, were collected. Survival curves were approximated through the Kaplan-Meier estimator and compared using the log-rank test. Proportional hazard Cox regression models were used for multivariate analyses while both unadjusted and adjusted hazard ratios (HR) were used for summarizing the studied differences. Results: The average duration of the treatment before discontinuation was 47.57 months (SD 32.63 months; median 41 months). The retention rates were 82% (2 years), 66% (5 years), and 58% (8 years). Median survival was 80 months (95% confidence interval. CI 36.9 to 123.01 months). The survival study revealed statistically significant differences between patients with arthritis (log-rank test, p < 0.001) and those who had previously received biological treatment (log-rank test, p = 0.026). The five-year prevalence in patients still under treatment was 80% (those without arthritis) and 54% (arthritis patients). In the multivariate analysis, only the patients with arthritis had a lower rate of drug survival. No statistically significant differences were observed for any of the other comorbidities studied. The first and second most frequent causes of discontinuation were secondary failure and arthritis inefficacy, respectively. Conclusion: Ustekinumab is a biological drug conferring high survival in plaque psoriasis patients. Ustekinumab survival is lower in patients with arthritis.

[Subcutaneous infection by Curvularia pallescens in a lung transplant recipient: First report in Spain]. / Micosis cutánea por Curvularia pallescens en un paciente trasplantado pulmonar: primer caso descrito en España.

BACKGROUND: Curvularia is a filamentous dematiaceous fungus increasingly recognized as a pathogen in immunocompromised patients. The most common clinical entities associated with this fungus are allergic sinusitis, cutaneous infection and keratitis. In this article, a report on the first clinical case of Curvularia pallescens cutaneous infection in Spain and its treatment is described. CASE REPORT: A 68 year-old man with a history of lung transplantation presented to Dermatology Unit due to a skin lesion in the knee that had been evolving for 6 months. A skin biopsy was performed for its study. In the histopathological study, an intense and non-specific inflammatory reaction in the dermis was observed, and with Grocott stain and periodic acid Schiff abundant septate hyphae and spores were found in the dermis. The culture of the sample revealed a filamentous fungus whose microscopic examination allowed to identify the genus as Curvularia. Using MALDI-TOF mass spectrometry and molecular identification, the fungus was finally identified as Curvularia pallescens. The patient underwent surgical resection of the lesion and was treated with posaconazole, evolving favorably. CONCLUSIONS: The species of Curvularia should be considered causal agents of fungal skin infections in immunosuppressed patients. This clinical case, which showed good clinical response after surgical resection and treatment with posaconazole, is the first described in Spain due to this species.

Micosis cutánea por Curvularia pallescens en un paciente trasplantado pulmonar: primer caso descrito en España / Subcutaneous infection by Curvularia pallescens in a lung transplant recipient: first report in Spain

ANTECEDENTES: El género Curvularia incluye hongos filamentosos dematiáceos cada vez más reconocidos como patógenos en pacientes inmunocomprometidos. Las entidades clínicas más comunes con las que se asocia este hongo son la sinusitis alérgica, la infección cutánea y la queratitis. En este trabajo se describe el primer caso descrito en España de infección cutánea por Curvularia pallescens y su tratamiento. CASO CLÍNICO: Un varón de 68 años con antecedente de trasplante pulmonar acudió al servicio de dermatología por presentar una lesión cutánea en la rodilla de 6 meses de evolución. Se realizó una biopsia cutánea para estudio. La histopatología mostró una intensa reacción inflamatoria inespecífica en la dermis y mediante la tinción de Grocott y ácido peryódico de Schiff se observaron abundantes hifas septadas y esporas en la dermis. El cultivo de la muestra reveló un hongo filamentoso cuyo examen microscópico permitió identificar el género como Curvularia. Mediante espectrometría de masas MALDI-TOF e identificación molecular, el hongo finalmente se identificó como Curvularia pallescens. Se realizó resección quirúrgica de la lesión y el paciente recibió tratamiento con posaconazol, con resolución clínica de la lesión. CONCLUSIONES: El género Curvularia debe ser considerado un agente causal de micosis subcutáneas en pacientes inmunodeprimidos. Este caso clínico constituye el primero descrito en España producido por esta especie, el cual presentó buena respuesta clínica tras resección quirúrgica y tratamiento con posaconazol

Progressive facial hemiatrophy with associated osseous lesions.

Progressive facial hemiatrophy (PFH) is a rare condition characterized by the slow, progressive appearance of a unilateral facial atrophy that affects the skin, subcutaneous tissue, muscle and bone. We report the case of a 60-year-old female patient whose cutaneous symptoms commenced in 1987 in the form of a purplish erythema on the left side of her face and neck, which subsequently remitted giving rise to an indurated region in the left maxillary region. Since 1995 until the present day, she has developed facial hemiatrophy on the left side accompanied by progressive osseous reabsorption of the upper maxilla and left mandible with atrophy of soft tissue. The association of the onset of PFH with progressive osteolysis of the maxilla has not been previously reported in an adult patient.

[Acquired flat angiomas in the form of a port-wine stain]. / Angiomas planos adquiridos en mancha de vino de Oporto.

The development of flat angiomas in the form of a "port-wine stain" is an infrequent event in adults. We describe two cases of acquired flat angioma in the form of a "port-wine stain", which began in the second decade of life and grew slowly and steadily until reaching a large size. In the first case, it affected the front and back of the trunk, and in the second patient, the neck and left shoulder. Histopathology showed ectatic vessels in the papillary and reticular dermis, with no proliferation of endothelial cells.

Metastatic eccrine porocarcinoma: a 5.6-year follow-up study of a patient treated with a combined therapeutic protocol.

BACKGROUND: Metastatic eccrine porocarcinoma (EP) is an uncommon, malignant, and potentially lethal neoplasm that arises from the eccrine sweat glands. OBJECTIVE: To present the 5.6-year follow-up study of a male patient with metastatic EP, highlighting the widespread cutaneous involvement and the response to the treatment carried out. METHODS: We describe the evolution of the tumor and the combined therapy carried out and review the treatments employed in previously reported cases, comparing them with ours. RESULTS: The patient developed multiple cutaneous and regional lymph node metastases 15 months after surgical excision of the primary tumor. He was treated with prophylactic lymphadenectomy, radiotherapy, and oral isotretinoin, subsequently substituted by tegafur. We have not found evidence of distant metastases after a 5.6-year follow-up. CONCLUSIONS: The optimum treatment for metastatic EP is not standardized, and the results obtained to date were generally poor. In this context, we consider it of interest to highlight the response of our patient to the therapeutic regime employed, which may be advantageous in future cases of this rare tumor.

Transformación de la micosis fungoide/síndrome de Sézary a linfoma de células grandes / Transformation of mycosis fungoides/Sézary syndrome to large cell lymphoma

Introducción: la micosis fungoide (MF) y el síndrome de Sézary (SS) son linfomas cutáneos caracterizados por una proliferación de linfocitos T de pequeño o mediano tamaño. Algunos pacientes con MF/SS desarrollan una transformación a linfoma de células grandes (LCG).Objetivo: estudiar las características clinicopatológicas e inmunohistoquímicas, así como el pronóstico de seis casos de MF/SS que en un grupo de 50 pacientes con esa enfermedad evolucionaron a LCG. Material y métodos: aceptamos como casos transformados a LCG aquellos en los cuales las células grandes superaban el 25% del infiltrado o formaban nódulos microscópicos. Resultados: la localización inicial del LCG fue en la piel en cuatro casos, manifestándose en forma de tumores cutáneos; los dos casos restantes se presentaron con clínica extracutánea. Los hallazgos anatomopatológicos fueron característicos de LCG. Desde el punto de vista inmunohistoquímico todos los casos expresaron antígenos linfoides de línea T; la inmunotinción con CD30 fue positiva en tres; un porcentaje alto de células tumorales mostraron positividad para el antígeno de proliferación nuclear Ki-67. Todos los pacientes fallecieron en relación directa con su linfoma y la supervivencia mediana desde el diagnóstico de la MF/SS fue de 8 meses, mientras que fue de 114 meses en los 44 casos restantes. Conclusión: la transformación de la MF/SS a LCG se asocia a un comportamiento agresivo de la enfermedad, con supervivencia baja (AU)
