Identification and molecular characterization of Orfvirus infection in occupationally exposed women inSouth America

Abstract Contagious Ecthyma (CE) is a severe exanthematous dermatitis caused by the Orf virus (ORFV) that mainly affects domestic small ruminants such as sheep and goats. It is a worldwide-distributed occupational zoonosis, particularly infecting those in close contact with animals or animal products such as shepherds, farmers and veterinarians, among others. In the present work, we report the first human CE case confirmed in Argentina. A phylogenetic analysis based on four gene sequences of the isolated strain responsible for the disease showed that this isolate grouped with other ORFV sequences that caused reported CE cases in sheep from the same Argentine province. We also sequenced a sample from a Chilean human case reported in 2017, whose phylogenetic analysis showed that it groups together with other Argentine isolates from locations close to the border with Chile. Keywords: Contagious Ecthyma; Dermatitis; Human Orf; Zoonosis; Molecular characterization.

Resumen El ectima contagioso (EC) es una dermatitis exantemática grave causada por el virus Orf (ORFV), que afecta mayormente a pequeños rumiantes domésticos, como ovinos y caprinos. Es una zoonosis ocupacional con distribución mundial, infecta a humanos en estrecho contacto con animales o sus productos, como granjeros, esquiladores y veterinarios, entre otros. En este trabajo se informa el primer caso humano de EC confirmado en Argentina. Un análisis filogenético basado en cuatro genes de la cepa responsable de este caso mostró que el aislamiento agrupa con otras secuencias de ORFV que causaron casos en ovinos en la misma provincia argentina. También se secuenció una muestra del caso de ectima humano reportado en Chile en 2017 y el análisis filogenético mostró que dicho aislamiento forma un grupo con otros aislamientos argentinos de localidades cercanas a la frontera con Chile. Palabras clave: Ectima contagioso; Dermatitis; Orf en humanos; Zoonosis; Caracterización molecular.

Molusco contagioso del párpado: manifestación cutánea de inmunosupresión / Eyelid molluscum contagiosum: Cutaneous manifestation of immunosuppression

Resumen El molusco contagioso es una infección viral cutánea, usualmente benigna y autolimitada, causada por un virus del género Molluscipoxvirus. Es más frecuente en niños, adultos jóvenes sexualmente activos e inmunosuprimidos. La lesión clínica característica es una pápula umbilicada eucrómica o de tono perlado, que se disemina rápidamente y puede afectar cualquier superficie muco-cutánea, aunque la localización en los párpados es atípica. Se presentan dos casos de pacientes jóvenes inmunosuprimidos, con moluscos contagiosos palpebrales, en quienes el diagnóstico clínico inicial fue incorrecto. Se enfatiza la importancia de diagnosti car oportunamente las lesiones papulares que afectan la piel del párpado ya que la presencia de molusco contagioso en esta zona se considera una manifestación cutánea de inmunosupresión.

Abstract Molluscum contagiosum is a cutaneous viral infection, usually benign and self-limited, caused by the molluscum contagiosum virus, of the genus Molluscipoxvirus. It is more common in pediatric population, sexually active young people and immunosuppressed patients. Clinical presentation is characterized by umbilicated white to flesh-colored or pearly papules, which rapidly spread and can affect any muco-cutaneous membrane. Although the eyelid presentation is atypical, we herein present two young, immunosuppressed patients, with diagnosis of palpebral molluscum contagiosum, in which the initial clinical diagnosis was wrong. We emphasize the importance in making a timely diagnosis of papular lesions localized on the eyelids and the correlation of these lesions as a cutaneous manifestation of immunosuppression.

Molusco contagioso: actualización y casos clínicos / Molluscum contagiosum: an update and clinical cases

El molusco contagioso es una patología viral benigna muy frecuente, exclusiva del ser humano, y causada por un virus no clasificado del grupo de los Poxvirus. Las manifestaciones clínicas de la enfermedad inclu-yen lesiones en la piel, que pueden variar desde una pequeña pápula a un nódulo de mayor tamaño, pre-sentándose en forma solitaria o múltiple, dependien-do del estado inmunitario del paciente y del tiempo de evolución del proceso morboso. El estudio histo-patológico es importante para el diagnóstico, aunque en numerosas ocasiones éste se define clínicamen-te. Además del patrón histológico tradicional, y más frecuente, que exhibe hiperplasia e hipertrofia de la epidermis, se han descripto variantes poco usuales, cuyas características dependen, entre otros factores, de la sobreinfección y de la respuesta inmunitaria del paciente. En este trabajo se describen los rasgos ge-nerales del molusco contagioso y luego se presentan varios casos clínicos, uno de los cuales exhibe ma-nifestación inusual en la semimucosa del labio. Por último, se realizan comentarios referentes a la im-portancia que tiene para el odontólogo conocer esta patología y estar capacitado para detectarla, de modo de evitar sus complicaciones y su diseminación (AU)

Molluscum contagiosum is a very common benign viral pathologythat affects exclusively humans and is caused by an unclassified virus of the Poxvirus family. Clinical manifestations include skin lesions such as papule or nodule, which may range from a small papule to a larger nodule, presenting either solitary or multiple, depending on the immune status of the patient and the time of evolution of the morbid process. Histopathological study is important for the diagnosis, although in numerous occasions it is defined clinically. Classical and more frequent histology pattern exhibits hyperplasia and hypertrophy of the epidermis; however, distinct characteristics may occur depending on factors like superinfection and immune response of patients. This article describes general aspects of molluscum contagiosum and exposes several clinical cases, one of which exhibits an unusual manifestation in the semimucosa of the lip. Finally, comments are made regarding the importance for dentists to learn about the existence of this pathology and be able to recognize it in order to avoid its complications and spread (AU)

Molluscum Contagiosum Associated with Acquired Immunodeficiency Syndrome: Experience in HIV outpatient care and literature review / Molusco contagioso associado à síndrome da imunodeficiência adquirida: experiência no atendimento em ambulatório de HIV e revisão da literatura

Introduction: Molluscum contagiosum is a dermatosis caused by a DNA virus of the family Poxvirus and genus Molluscipoxvirus, affecting mainly children, sexually active adults, atopic individuals and immunocompromised patients, especially those with human immunodeficiency virus (HIV) infection. Objective: To describe our experience in caring for patients living with HIV who presented with extensive and severe Molluscum contagiosum, and to conduct a literature review on the subject as well. Methods: An electronic search was carried out in the MEDLINE/PubMed and SciELO databases and in the books: ATLAIDS and AZULAY limited to the period of January 2017 to June 2021. Results: Four clinical cases are reported in people living with HIV with extensive lesions normally not found in immunocompetent patients. The treatment performed in the cases reported in this article was the punctual application of 90% trichloroacetic acid (TCA) to each lesion, with complete remission of the clinical presentation in two patients over a period of three and six months. The other two patients did not receive treatment for molluscum contagiosum as they died because of pulmonary complications. Conclusion: Infection with Molluscum contagiosum in people living with HIV has disseminated forms with large-volume lesions, with substantial stigmatizing aesthetic impairment, and treatment with 100% TCA is quite effective.

Introdução: Molusco contagioso é uma dermatose causada por um vírus de DNA da família poxvírus e do gênero Molluscipoxvirus. Afeta principalmente crianças, adultos sexualmente ativos, indivíduos atópicos e pacientes imunodeprimidos, especialmente aqueles com infecção pelo vírus da imunodeficiência humana (HIV). Objetivo: Descrever a experiência no atendimento de pacientes vivendo com HIV que apresentaram quadro de molusco contagioso extenso e grave, além de realizar uma revisão da literatura sobre o tema. Métodos: Foi realizada uma pesquisa eletrônica nas bases de dados MEDLINE/PubMed e SciELO e nos livros ATLAIDS e AZULAY, limitada ao período de janeiro de 2017 a junho de 2021. Resultados: São relatados quatro casos clínicos em pessoas que vivem com HIV com lesões extensas normalmente não encontradas em pacientes imunocompetentes O tratamento realizado nos casos relatados nesse artigo foi a aplicação pontual de ácido tricloroacético (ATC) 100% em cada lesão, com a remissão completa do quadro clínico em dois pacientes em um período de tempo entre três e seis meses. Os outros dois pacientes não receberam tratamento para o vírus do molusco contagioso pois evoluíram para óbito em razão de complicações pulmonares. Conclusão: A infecção pelo molusco contagioso em pessoas vivendo com HIV apresenta formas disseminadas com lesões de grande volume, com comprometimento estético estigmatizante importante, e o tratamento com ATC 90% é bastante eficaz.

Lesiones vesiculares, no siempre son varicela / Bladders, not always varicela

El impétigo ampolloso o bulloso es una enfermedad infectocontagiosa de la piel, causada por Staphylococcus aureus y mediada por toxina. Se caracteriza por la aparición de ampollas flácidas sobre lesiones vesiculares iniciales. Es importante el diagnóstico diferencial en estadios iniciales con otras patologías que cursan con lesiones vesiculosas, como la varicela. La elección del tratamiento se basa en la extensión, localización y profundidad de las lesiones, utilizando siempre antibioterapia contra S. aureus y comprobando la sensibilidad antibiótica debido a la creciente prevalencia de S. aureus resistente a la meticilina (SARM) (AU)

Bullous impetigo is an infectious-contagious skin disease toxin-mediated, caused by Staphylococcus aureus. It’s characterized by the appearance of flaccid blisters on initial vesicular lesions. It’s important the differential diagnosis with other diseases involving vesicular lesions, such as chickenpox in early stages. The choice of treatment is based on the extent, location and depth of the lesions, always using antibiotic therapy against S. aureus and checking antibiotic sensitivity due to the increasing prevalence of MRSA (methicillin resistant S. aureus) (AU)

Molusco contagioso como complicação de tatuagem: um relato de caso e revisão da literatura / Molluscum contagiosum as a tattoo complication: a case report and literature review

A tatuagem é uma prática antiga e muito popular atualmente. Os pigmentos utilizados mudaram com o tempo, mas continuam apresentando composições variadas e pouco regulamentadas. Há inúmeros casos descritos de efeitos adversos pós-tatuagem, em sua maioria infecciosos, e reações de hipersensibilidade. Relatamos o caso de uma mulher de 64 anos, hígida, com pápulas nas sobrancelhas um mês após realizar micropigmentação. A biópsia excisional fez o diagnóstico de molusco contagioso, e o tratamento foi realizado com curetagem das lesões. Na literatura, existem poucos relatos de disseminação de molusco contagioso causada por tatuagem.

Tattooing is an ancient practice and very popular nowadays. The pigments used have changed over time but still present varied and poorly regulated compositions. There are many described cases of adverse effects after tattooing, mainly infectious and hypersensitivity reactions. We report the case of a 64-yearold woman, healthy, with papules on her eyebrows one month after performing micropigmentation. The excisional biopsy diagnosed molluscum contagiosum, and the lesions were curetted. There are few reports in the literature of the spread of molluscum contagiosum caused by tattooing

Presentación atípica de molusco contagioso: compromiso ocular bilateral en paciente con VIH / Atypical presentation of molluscum contagiosum: bilateral ocular involvement in a patient with HIV

La infección por molusco contagioso (MC) en adultos se asocia frecuentemente a transmisión sexual y/o inmunodepresión, por ejemplo, por VIH. En este grupo, la manifestación clínica suele ser atípica. A continuación, se presenta el caso de un paciente con diagnóstico de VIH, bajo recuento de CD4 y carga viral elevada que consulta por múltiples MC en genitales, tronco, cara y ojos además de conjuntivitis en ojo derecho. Se mantuvo terapia antirretroviral (TARV) y se indicó tratamiento para conjuntivitis. La infección por MC en pacientes con VIH se asocia a etapas SIDA con un aumento de los casos a menor recuento de linfocitos CD4, generalmente menor a 200 cel/mL. La pobre respuesta inmune celular de estos pacientes explica su comportamiento clínico atípico. Este grupo presenta una mayor mortalidad que el de pacientes seropositivos sin MC, lo que se explica por la mayor inmunosupresión asociada. El diagnóstico es clínico, aunque podría verse entorpecido cuando hay compromiso ocular por la presencia de lesiones atípicas que hacen necesario considerar diversos diagnósticos diferenciales. El tratamiento es controversial y tiende a existir una baja respuesta y recidiva frente a terapias convencionales en pacientes con VIH cuando la inmunosupresión es marcada por el recuento CD4 muy bajo. La TARV pareciera ser la mejor alternativa para su tratamiento, sin embargo, es importante considerar posibles complicaciones asociadas, como la instauración de síndrome de restauración inmunológica una vez iniciada. Esto podría traducirse en lesiones oculares graves cuando existe compromiso en este órgano

Molluscum contagiosum (MC) infection in adults is frequently associated with sexual transmission and / or immunosuppression, for example by HIV. In this group, the clinical manifestation is usually atypical. Herein we present the case of a patient with a diagnosis of HIV, a low CD4 count and a high viral load who consulted for multiple MC in the genitals, trunk, face and eyes, as well as conjunctivitis in the right eye. Antiretrovitral therapy (ART) was maintained and treatment for conjunctivitis was indicated. MC infection in HIV patients is associated with AIDS stages with an increase in cases with a lower CD4 lymphocyte count, generally less than 200 cells / mL. The poor cellular immune response of these patients explains their atypical clinical behavior. This group presents a higher mortality than that of seropositive patients without MC, which is explained by the greater associated immunosuppression. The diagnosis is clinical, although it could be hampered when there is ocular compromise due to the presence of atypical lesions that make it necessary to consider various differential diagnoses. Treatment is controversial and there tends to be a poor response and relapse to conventional therapies in patients with HIV when immunosuppression is marked by a very low CD4 count. ART seems to be the best alternative for its. However, it is important to consider possible associated complications such as the onset of immune restoration syndrome once it has been started. This could translate into serious eye injuries when this organ is compromised

Frequency of microorganisms isolated at different stages of lactation and milk production loss associated with somatic cell count and to mastitis-causing pathogens / Frequência de microrganismos isolados em diferentes fases da lactação e perda de produção de leite associada à contagem de células somáticas e aos patógenos causadores de mastite

The aim of this study was to evaluate the frequency of isolation of agents causing subclinical mastitis in a herd and to estimate production losses associated with SCC> 200,000cells/mL. Three 7-day interval microbiological cultures were performed in all lactating animals from the same farm that was evaluated from June to July. To evaluate the negative and positive isolation frequencies between the lactation phases, a Chi-square test was performed. Simple linear regressions were performed to evaluate the lactation curve of animals grouped by pathogens isolated from negative cows in the microbiological culture and with SCC <200,000cells/mL. To estimate the production losses between the groups, regression coefficients were used. Results found in this experiment were: Culture-negative cows with SCC ≥ 200,000cells/mL, cows testing positive in milk culture, with SCC <200,000cells/mL and cows testing positive in milk culture, with SCC ≥ 200,000cells/mL. Milk production was -3.5; -0.5 and -4.27kg, respectively, when compared to culture-negative cows with SCC <200,000cells/mL. Cows infected with yeast cells, Coagulase-negative staphylococci (CNS), Staphylococcus aureus and environmental streptococci produced -3.42; -0.5; -0.168 and -2.5kg of milk when compared to culture-negative cows with SCC <200,000cells/mL. SCC indicates an inflammatory reaction in the mammary gland and it is directly associated with milk production losses and with presence of microorganisms in the mammary gland.(AU)

O objetivo deste estudo foi avaliar a frequência de isolamento de agentes causadores de mastite subclínica em um rebanho e estimar as perdas de produção associadas com CCS>200.000 cél./mL. Três cultivos microbiológicos intervalados por sete dias foram realizados em todos os animais em lactação da propriedade avaliada, no período de junho a julho. Para avaliar as frequências de isolamento negativo e positivo entre as fases da lactação, foi realizado um teste de qui-quadrado. Foram realizadas regressões lineares simples para avaliar a curva de lactação dos animais agrupados por patógenos isolados em relação a vacas negativas na cultura microbiológica e com CCS < 200.000 cél./mL. Os coeficientes das regressões foram utilizados para estimar as perdas de produção entre os grupos. Vacas com resultado negativo na microbiologia, mas com CCS ≥ 200.000 cél./mL, positivas na microbiologia com CCS < 200.000 cél./mL e positivas com CCS ≥ 200.000 cél./mL, produziram por dia, respectivamente, -3,5; -0,5 e -4,27kg de leite em relação às vacas negativas com CCS < 200.000 cél./mL. Vacas infectadas com células leveduriformes, Staphylococcus coagulase negativa, Staphylococcus aureus e Streptococcus ambientais produziram, respectivamente, -3,42; -0,5; -0,168 e -2,5kg de leite, comparadas a vacas negativas com CCS < 200.000 cél./mL. A CCS, indicativa de reação inflamatória, encontra-se diretamente associada às perdas de produção de leite, assim como a presença do microrganismo na glândula mamária.(AU)

Cambios electrocardiográficos en pacientes con VIH con y sin inhibidores de proteasa vs NNRTI / Differences in electrocardiographic changes in HIV patients with and without treatment with protease inhibitors vs NNRTI

Resumen ANTECEDENTES La infección por el virus de inmunodeficiencia humana (VIH) incrementa la prevalencia de prolongación del intervalo QT corregido (QTc), lo que es un factor independiente de eventos de enfermedad cardiovascular en esta población. En la bibliografía mundial se asocia este cambio con la administración de los antirretrovirales inhibidores de proteasa y efavirenz. Sin embargo, no se conocen datos de estos cambios en la población mexicana. MATERIAL Y MÉTODO Estudio prospectivo observacional en el que se seleccionaron expedientes de marzo de 2015 a mayo de 2016 de la consulta externa del Instituto Nacional de Enfermedades Respiratorias (INER); se dividieron en dos grupos: sin tratamiento, por reciente diagnóstico, y con tratamiento antirretroviral. Se registraron datos clínicos, tratamiento farmacológico, electrocardiograma y química sanguínea. RESULTADOS No se encontraron diferencias entre ambos grupos respecto a edad ni electrólitos séricos. Tampoco se encontró relación entre la prolongación del QTc con efavirenz o los inhibidores de proteasa. Raltegravir disminuyó la duración del QTc (p = 0.001) mientras que la coinfección por molusco contagioso se asoció con prolongación del QTc (p = 0.02). CONCLUSIÓN En nuestro estudio no logramos demostrar en población mexicana relación de la prolongación del QTc con los antirretrovirales de primera ni segunda línea. Se requieren más estudios para determinar la importancia clínica del efecto de raltegravir y molusco contagioso en el QTc.

Abstract BACKGROUND Human immunodeficiency virus (HIV) infection increases the prevalence of QTc prolongation (QTc), which is an independent factor of cardiovascular disease events in this population. In the world literature this change is associated with the use of the protease inhibitors and efavirenz antiretrovirals. However, no data are available on these changes in the Mexican population. MATERIAL AND METHOD A prospective observational study was done selecting records from March 2015 to May 2016 of the external consultation of the National Institute of Respiratory Diseases (INER), Mexico City; they were divided into two groups, those without treatment, because recent diagnosis, and with antiretroviral treatment. We recorded clinical data, pharmacological treatment, electrocardiogram and blood chemistry. RESULTS We found no differences between the two groups regarding age or serum electrolytes. We found no association between QTc prolongation and efavirenz or protease inhibitors. Raltegravir decreased QTc duration (p = 0.001) while molluscum contagiosum coinfection was associated with QTc prolongation (p = 0.02). CONCLUSION In our study, we failed to demonstrate in Mexican population association of QTc prolongation with first- and second-line antiretrovirals. More studies are needed to determine the clinical significance of the effect of raltegravir and molluscum contagiosum on QTc.

Virus orf en humanos, confirmación molecular de un caso clínico en Chile / Orf virus in human, confirmation in case report from Chile

Resumen La infección por el virus orf, también conocida como ectima contagioso, es reconocida una zoonosis ocupacional. Se diagnostica por lesiones cutáneas que evolu cionan rápidamente desde máculas a pápulas, vesículas y pústulas. Se presenta el caso clínico de una estudiante de medicina veterinaria que había tenido contacto con caprinos, clínicamente sanos y sin lesiones aparentes, hacía 19 días. Presentó dos lesiones vesiculares que coalescieron hasta formar una lesión de mayor tamaño rodeada por un halo eritematoso. Las lesiones fueron compatibles con la presentación clásica de las producidas por el virus orf en humanos. Se confirmó la presencia del virus orf mediante una RPC anidada del tejido de biopsia. Es uno de los primeros casos confirmados mediante técnicas moleculares en seres humanos en Chile.

Infection with the orf virus, also known as contagious ecthyma, is recognized as an occupational zoonosis worldwide. It is diagnosed by cutaneous lesions that progress rapidly from macules to papules, vesicles and pustules. The clinical case of a student of veterinary medicine who had had contact with goats, clinically healthy and without apparent lesions, which occured 19 days ago, is reported. She presented two vesicular lesions that coalesced to form a larger lesion surrounded by an erythematous halo. The lesions were compatible with the classical presentation of those produced by the orf virus in humans. The presence of the orf virus was confirmed by a nested PCR from biopsy tissue. It is one of the first cases confirmed by molecular techniques in humans in Chile.

Imiquimode e curetagem para o tratamento do molusco contagioso: um estudo comparativo / Imiquimod and curetage for the treatment of molluscum contagiosum: a comparative study

Introdução: Molusco contagioso é uma dermatovirose causada por um poxvírus. Na literatura há descrição de diferentes abordagens terapêuticas dessa infecção. Objetivo: Avaliar a eficácia do imiquimode para tratamento de molusco contagioso de forma isolada e associada à curetagem. Métodos: Grupo A, 20 pacientes utilizaram imiquimode 5% creme, 3 vezes por semana por 6 semanas e Grupo B, 10 pacientes que utilizaram creme base, 3 vezes por semana por 6 semanas. Após estas 6 semanas, todos os pacientes se submeteram à curetagem. Resultados: Grupo A, na sexta semana diminuição de 31% no número de lesões, com uma efetividade da curetagem de 97,6%; Grupo B na sexta semana um aumento de 4,8% no número de lesões e uma efetividade da curetagem de 81,1%. A média do nível de dor durante a curetagem foi de 1,8 para o Grupo A e 3,0 para o Grupo B. Conclusões: Por aumentar a taxa de eliminação de lesões de molusco contagioso e diminuir a dor quando o processo de curetagem é realizado após uso do imunomodulador, concluímos que a associação de imiquimode 5% em creme com curetagem possa ser uma possibilidade terapêutica.

Introduction: Molluscum contagiosum is a dermatovirosis caused by a poxvirus. In the literature there are descriptions of different therapeutic approaches of this infection. Objective: To evaluate the efficacy of imiquimod ­ isolated and associated with curettage ­ in the treatment of molluscum contagiosum. Methods: Group A: 20 patients used 5% imiquimod cream 3 times a week for 6 weeks. Group B: 10 patients used a creamy base 3 times a week, for 6 weeks. After the initial 6 weeks, all patients underwent curettage. Results: Group A: 31% decrease in the number of lesions in the 6th week, with a curettage effectiveness of 97.6%; Group B: 4.8% increase in the number of lesions in the 6th week, with a curettage effectiveness of 81.1%. The mean value for the pain level during curettage was 1.8 for Group A and 3.0 for Group B. Conclusions: Due to the facts that the rate of cure of contagious molluscum lesions increased and the pain decreased when the curettage procedure was conducted after the use of the immunomodulator, it was possible to conclude that the association of 5% imiquimod cream to the curettage may be a therapeutic possibility.

Molluscum contagiosum: posible papel patogenésico en las enfermedades autoinmunes. Reporte preliminar de 111 casos / Molluscum contagiosum: possible role in pathogenesis of autoimmune diseases. preliminary report of 111 cases

Objetivo: mostrar los resultados de una casuística de 111 pacientes diagnosticados por clínica del virus del molusco contagioso (VMC), en los cuales existe una alta prevalencia de enfermedades autoinmunes y de patologías dermatológicas crónicas. Aunque la infección dérmica por el virus del molusco contagioso (VMC) se conoce hace más de 140 años, es sólo durante el presente siglo que se ha difundido el conocimiento de esta patología, en gran parte porque ha existido un aumento alarmante en su incidencia y prevalencia. La bibliografía disponible destaca su larga evolución y resistencia a los tratamientos en boga, ninguno aprobado por la Administración de Alimentos y Medicamentos de los Estados Unidos (FDA, por sus siglas en inglés), pero no menciona complicación del VMC (excepto la sobre infección originada por el rascado). Además de una revisión actualizada de esta dermatosis, el presente artículo muestra una casuística de 111 pacientes (desde infantes de 3 meses hasta adultos de 58 años), portadores del VMC en los cuales parece existir una alta incidencia de patologías reactivas, todas ellas con un patrón de actividad autoinmune y relacionadas en tiempo al inicio del cuadro viral. Conclusión: aunque los resultados preliminares presentados requieren de un mejor manejo estadístico y metodológico, los datos sugieren fuertemente una probable relación entre el VMC y las enfermedades autoinmunes (EAI). Es un hecho que se requieren estudios confirmativos más extensos que avalen o rechacen dicha asociación. (AU)

Objective: to show the cohort of 111 patients clinically diagnosed of molluscum contagiosum virus (MCV or VMC), in who exists a very high prevalence of autoimmune diseases (AID or EAI) and chronic dermatologic conditions. Despite the clinical entity of VMC has been described in medical literature 140 years ago, just present century has brought awareness of its clinical aspects, diagnosis and treatment, mainly because of the explosive spreading of this highly contagious dermatitis. Even when there are several proposed treatments for this virus, no one has been conclusively effective for its eradication and no one has been approved by FDA. Beside an update of clinical picture of VMC, this paper presents a cohort of 111 patients, all of them clinically diagnosed of VMC, aged from 3 months to 58 years; interestingly patients show a very high coexistence of autoimmune diseases and chronic dermatologic conditions as rosaceous, oral and skin lichen.

Conclusión: aunque los resultados preliminares presentados requieren de un mejor manejo estadístico y metodológico, los datos sugieren fuertemente una probable relación entre el VMC y las enfermedades autoinmunes (EAI). Es un hecho que se requieren estudios confirmativos más extensos que avalen o rechacen dicha asociación...

To show the cohort of 111 patients clinically diagnosed of molluscum contagiosum virus (MCV or VMC), in who exists a very high prevalence of autoimmune diseases (AID or EAI) and chronic dermatologic conditions. Despite the clinical entity of VMC has been described in medical literature 140 years ago, just present century has brought awareness of its clinical aspects, diagnosis and treatment, mainly because of the explosive spreading of this highly contagious dermatitis. Even when there are several proposed treatments for this virus, no one has been conclusively effective for its eradication and no one has been approved by FDA. Beside an update of clinical picture of VMC, this paper presents a cohort of 111 patients, all of them clinically diagnosed of VMC, aged from 3 months to 58 years; interestingly patients show a very high coexistence of autoimmune diseases and chronic dermatologic conditions as rosaceous, oral and skin lichen...

Inmunodeficiencia combinada con compromiso cutáneo asociada a mutación en DOCK8 / Combined immunodeficiency with cutaneous manifestations associated with DOCK8 mutation

Diferentes inmunodeficiencias primarias se caracterizan por niveles elevados de IgE e infecciones cutáneas de origen viral. Describimos el caso de un niño de 2 años y 8 meses de edad, con inmunodeficiencia combinada, dermatitis y molusco contagioso diseminado. El paciente presentaba niveles aumentados de IgE, eosinofilia y marcada linfopenia a predominio de TCD8. Se encontraron alteraciones en los ensayos funcionales por cultivo y en la respuesta a la vacunación. Resultados normales de la proteína ZAP-70, funcionalidad NK y niveles de HLA I, tendientes a verificar alteraciones cuantitativas y funcionales de las células citotóxicas, llevaron a la sospecha de deficiencia en el gen DOCK8. El resultado positivo del estudio molecular, junto con las características clínicas e inmunológicas del paciente, confirmaron el diagnóstico de esta nueva inmunodeficiencia, que, de acuerdo con nuestro conocimiento, sería el primer caso diagnosticado en un hospital pediátrico en nuestro país.

Different primary immunodeficiencies present increased levels of IgE and cutaneous infections of viral etiology. We report a case of a 2 y, 8 m old boy with combined immunodeficiency, dermatitis and disseminated molluscum contagiosum. The patient presented high titers of IgE, eosinophilia and pronounced TCD8 lymphopenia. Impaired proliferation assays and abnormal antibody response to vaccination were found. Normal results of ZAP-70 protein, NK function, and HLA I levels, to test quantitatives and functional defects of cytotoxic cells, lead us to suspect a mutation in DOCK8 gene. Positive result in molecular study together with clinical and immunology features in the patient confirmed the diagnosis of this new immunodeficiency, being to the authors ́ knowledge the first case recorded in a paediatric hospital in our country.

Do you know this syndrome? / Voce conhece esta sindrome?

The hyperimmunoglobulin E syndrome, or Job's syndrome is a rare primary immunodeficiency characterized by recurrent skin abscesses, recurrent respiratory tract infections, and high levels of IgE, eosinophilia, bone and dental changes. We report the case of a fourteen-year-old male patient presenting this disease, with both typical and also some relatively sporadic manifestations. We performed a literature review on the syndrome and its associated clinical findings.

A síndrome de hiperimunoglobulinemia E, ou síndrome de Job é uma imunodeficiência primária rara, caracterizada por abcessos cutâneos recorrentes, infecções de repetição do trato respiratório, títulos elevados de IgE, eosinofilia, alterações ósseas e dentárias. Relata-se o caso de um paciente do sexo masculino, 14 anos, portador da doença, com manifestações desde típicas a algumas relativamente esporádicas, fazendo-se uma revisão da síndrome e dos achados clínicos associados.
