Comportamiento clínico-epidemiológico del eritema nudoso en el Hospital Provincial Docente Clínico Quirúrgico León Cuervo Rubio / Epidemiological clinical behavior of erythema nodosum at the Provincial Teaching Clinical Surgical Hospital Leon Cuervo Rubio

RESUMEN Introducción: el eritema nudoso es la variante clínico-patológica más frecuente de la paniculitis. Es una reacción cutánea inmunológica en respuesta a un amplio espectro de agentes etiológicos. Objetivo: caracterizar el comportamiento clínico-epidemiológico del eritema nudoso. Materiales y métodos: se realizó un estudio descriptivo, prospectivo y longitudinal en pacientes con diagnóstico de eritema nudoso, ingresados en el Hospital Provincial Docente Clínico Quirúrgico León Cuervo Rubio, de Pinar del Río, en el período de enero de 2017 a diciembre de 2018. El universo estuvo constituido por 34 pacientes con diagnóstico clínico de eritema nudoso, hospitalizados en los servicios de Medicina Interna y Dermatología. Para la recogida de la información se utilizaron la historia clínica, el examen físico y los exámenes de laboratorio. Se utilizaron métodos teóricos, empíricos y estadísticos; de los últimos se empleó la estadística descriptiva a través de frecuencias absolutas y porcentaje. Resultados: el mayor grupo de pacientes estuvo entre 30 y 39 años, y fue del sexo femenino. Las lesiones fueron más frecuentes en los meses de invierno. El tipo de eritema nudoso idiopático prevaleció. Predominó el tiempo de evolución de 1 a 3 meses. Como causa secundaria predominaron las infecciones, y los tratamientos más usado fueron los antiinflamatorios no esteroideos. Conclusiones: se trata de una importante enfermedad de salud, cuyo un diagnóstico etiológico temprano permite un tratamiento adecuado. Resulta difícil su identificación y manejo tanto en la atención primaria como en la secundaria (AU).

ABSTRACT Introduction: erythema nodosum is the most common clinical-pathological variant of panniculitis. It is an immunological skin reaction in response to a wide spectrum of etiologic agents. Objective: to characterize the clinical-epidemiological behavior of erythema nodosum. Materials and methods: a descriptive, prospective and longitudinal study was carried out in patients with diagnosis of erythema nodosum, admitted to the Provincial Teaching Clinical Surgical Hospital León Cuervo Rubio, of Pinar del Río, in the period January 2017 to December 2018. The universe was formed by 34 patients with clinical diagnosis of erythema nodosum, hospitalized in the services of Internal Medicine and Dermatology. Medical records, physical examination and laboratory tests were used for the collection of information. Theoretical, empirical and statistical methods were used; descriptive statistics was used through absolute frequencies and percentage. Results: the largest group of patients was between 30 and 39 years, and they were female. Injuries were more frequent in the winter months. The type of idiopathic erythema nodosum prevailed. The time of evolution prevailed from 1 to 3 months. Infections predominated as a secondary cause, and the most commonly used treatments were non-steroidal anti-inflammatory drugs. Conclusions: it is an important health condition, whose early etiological diagnosis allows the proper treatment. Its identification and management in both primary and secondary care is difficult (AU).

Reacciones lepromatosas en pacientes adultos y pediátricos en un centro de referencia. Programa Nacional de Lepra, Paraguay / Lepromatous reactions in adults and pediatric outpatients in a reference center. National Lepra Program, Paraguay

Introducción la lepra, llamada también enfermedad de Hansen, es una afección de la piel y de los nervios periféricos, infectocontagiosa, causada por Mycobacterium leprae. Las reacciones lepromatosas se presentan aún con tratamiento y son expresiones de respuesta inmunitaria. Conocerlas es importante a fin de facilitar el abordaje. Objetivo determinar la frecuencia y tipo de reacciones lepromatosas en pacientes con diagnóstico de lepra que acuden al centro de referencia de Enfermedad de Hansen en el Hospital Distrital de San Lorenzo, de enero 2013 a diciembre 2015. Metodología observacional, descriptivo, retrospectivo de corte transverso. Resultados se incluyeron 217 pacientes, 72% presentaban lepra MB y 63% era de sexo masculino. La prevalencia de reacción lepromatosa fue 44%, siendo más frecuentes las de tipo 2 (65%). Se presentó reacción lepromatosa como debut de la enfermedad en 27 %. Treinta y tres pacientes presentaron de tres a doce episodios de reacción lepromatosa. El tratamiento fue talidomida y corticoides. Conclusiones la prevalencia de leprorreacciones fue cercana al 50%, predominando las de tipo 2. El tratamiento utilizado fue talidomida y/o corticoides dependiendo del tipo de reacción lepromatosa.

Introduction leprosy, wich is cause by Mycobacterium leprae, also known as Hansen's Disease, affects skin and peripheral nerves. Lepromatous reactions (LRs) are expressions of an immune reaction and remain as a major persistent problem. LRs are present even with appropriated treatment. Emphasis must be made in early diagnosis and prevention of the catastrophic consequences of LRs. Objective to determine the frequency and type of lepromatous reactions in leprosy patients with leprosy attending to reference center of Hansen´s Disease in the District Center Hospital in San Lorenzo, from January 2013 to December 2015. Methodology observational, retrospective cross sectional study. Results 217 patients were included, 72% with multibacillary leprosy. 63% were male. Lepromatous reactions were found in 44%, been more frequent Type II reaction, in 65% of cases. LRs as oset disease occurred in 27%. 33 patients presented from 3 to 12 episodes of lepromatous reaction. The number of LRs episodes per patient were 3 to 12. Thalidomide was used as treatment in Erithema Nodosum Leprosum (ENL) and corticosteroids for the other types de LRs. Conclusions prevalence of PRs were 50%, been more frecuent the type II. Reaction the treatment used was Thalidomide and/or corticosteroids depending on the type of lepromatosus reaction.

Examining ERBB2 as a candidate gene for susceptibility to leprosy (Hansen’s disease) in Brazil

Leprosy remains prevalent in Brazil. ErbB2 is a receptor for leprosy bacilli entering Schwann cells, which mediates Mycobacterium leprae-induced demyelination and the ERBB2 gene lies within a leprosy susceptibility locus on chromosome 17q11-q21. To determine whether polymorphisms at the ERBB2 locus contribute to this linkage peak, three haplotype tagging single nucleotide polymorphisms (tag-SNPs) (rs2517956, rs2952156, rs1058808) were genotyped in 72 families (208 cases; 372 individuals) from the state of Pará (PA). All three tag-SNPs were associated with leprosy per se [best SNP rs2517959 odds ratio (OR) = 2.22; 95% confidence interval (CI) 1.37-3.59; p = 0.001]. Lepromatous (LL) (OR = 3.25; 95% CI 1.37-7.70; p = 0.007) and tuberculoid (TT) (OR = 1.79; 95% CI 1.04-3.05; p = 0.034) leprosy both contributed to the association, which is consistent with the previous linkage to chromosome 17q11-q21 in the population from PA and supports the functional role of ErbB2 in disease pathogenesis. To attempt to replicate these findings, six SNPs (rs2517955, rs2517956, rs1810132, rs2952156, rs1801200, rs1058808) were genotyped in a population-based sample of 570 leprosy cases and 370 controls from the state of Rio Grande do Norte (RN) and the results were analysed using logistic regression analysis. However, none of the associations were replicated in the RN sample, whether analysed for leprosy per se, LL leprosy, TT leprosy, erythema nodosum leprosum or reversal reaction conditions. The role of polymorphisms at ERBB2 in controlling susceptibility to leprosy in Brazil therefore remains unclear.

Reacciones por lepra en un centro de referencia nacional en Colombia / Leprosy reactions in a Colombian national reference centre

Introducción. Colombia es el país de América con mayor proporción de casos nuevos de lepra con discapacidad grave. Para disminuir tal discapacidad se requiere el control de las reacciones, principal causa del daño neural en esta enfermedad. Objetivo. Describir las características clínicas y epidemiológicas y el tratamiento de los pacientes con reacciones de tipo 1 y 2 que consultaron al Centro Dermatológico Federico Lleras Acosta. Materiales y métodos. Se trata de un estudio descriptivo que incluyó la población de pacientes con diagnóstico clínico de reacciones de tipo 1 y de tipo 2 por lepra, que acudieron al centro entre los años 2003 y 2009. Resultados. Se estudiaron 96 reacciones, 35 del tipo 1 y 61 del tipo 2. El 75 % de los pacientes provenía de los departamentos de Tolima, Cundinamarca, Santander y Boyacá. El 56 % de las reacciones de tipo 1 se presentaron antes de iniciar la poliquimioterapia para la lepra; el dermatólogo tratante consideró que las reacciones que se presentaron después de suspender la poliquimioterapia eran recaídas. El 94 % de las reacciones de tipo 1 se trataron con corticoides orales. El 97 % de los pacientes con reacciones de tipo 2 presentaron eritema nudoso, y todos se trataron con talidomida. Conclusiones.La clínica de la reacción de tipo 1 puede orientar al diagnóstico de la lepra en un paciente sin el antecedente de esta enfermedad (56 %). La reacción de tipo 1 que se inicia después de suspender la poliquimioterapia para la lepra, podría ser una manifestación de recaída de la enfermedad. La reacción de tipo 2 es más frecuente en hombres, con una relación hombre a mujer de 4:1. El 97 % de los pacientes con reacción de tipo 2 presentó eritema nudoso.

Introduction: Colombia is the country in America with the highest proportion of new cases leprosy with severe disability. To decrease such disability it is necessary to control these reactions, the main cause of nerve damage in leprosy. Objective: To describe the clinical and epidemiological characteristics and the treatment of patients with type 1 and 2 leprosy reactions who consulted the Centro Dermatológico Federico Lleras Acosta. Materials and methods: It is a descriptive study which included patients with clinical diagnoses of type 1 and 2 reactions who were seen in the center between 2003 and 2009. The town of origin of the patients, their age, clinical features and treatments were analysed. Results: We studied 96 reactions in 87 patients, 35 type 1 and 61 type 2 reactions; 75% of the patients came from the departments of Tolima, Cundinamarca, Santander and Boyacá; 77% of type 1 reaction occurred before the beginning of multidrug therapy for leprosy. The reactions that started after stopping the multidrug therapy were considered as a leprosy relapse. Conclusions: Correct identification of type 1 reaction by the general practitioner will allow the diagnosis of leprosy in a large percentage of patients. The type 1 reaction that begins after stopping the leprosy multidrug therapy may be a manifestation of a relapse of the disease.

Dermatologic manifestations in inflammatory bowel disease in Tunisia

Cutaneous manifestations are the most common extra intestinal manifestations associated with inflammatory bowel disease [IBD]. To assess the epidemio-clinical profile of skin manifestations in IBD. A prospective and descriptive study was conducted. We have examined skin, mucosa, hair and nails, of all patients with an IBD during one year. One hundred-ninety-five patients were included. Crohn's disease [CD] was noted in 154 cases [79.8%], ulcerous rectocolitis [UC] in 39 cases [21.2%] and inclassable IBD in 2 cases. Cutaneous manifestations were found in 91% of Crohn's patients and in 92% of UC patients. Granulomatous perianal skin lesions were the main cutaneous manifestations of CD [53%]. The most common affected sites were ano-perineal fistulae, perianal and perineal fissures and oedematous and infiltrated perianal and genital plaques. Reactive lesions [Erythema nodosum, Pyoderma gangrenosum, Aphthous stomatitis] were noted in 14 cases. Skin manifestations due to malabsorption were also frequently observed [101 cases: 51.7%].Other dermatoses implicating various mechanisms such as psoriasis, alopecia areata, vitiligo, rosacea, lichen planus, were also noted. Adverse skin manifestations due to treatment [folliculitis, acne, macula-papular rash and DRESS syndrome] were present in 16 cases. Our series is characterized by a high frequency of cutaneous manifestations associated to IBD. A better recognition of these skin manifestations by the physician may improve their management
