RESUMO

La erupción variceliforme de Kaposi (EVK) es la diseminación cutánea del virus herpes simple (VHS), siendo la etiología más frecuente el VHS tipo 1. Suele presentarse en pacientes con enfermedades cutáneas de base o por lesiones agudas de la barrera epidérmica. La sospecha clínica se confirma mediante reacción en cadena de la polimerasa, aislamiento del virus en cultivo o mediante anticuerpos monoclonales realizados de una muestra extraída de las lesiones cutáneas. La complicación más frecuente es la sobreinfección bacteriana por Staphylococcus aureus y el tratamiento de elección es aciclovir oral o intravenoso, en función de la gravedad. En la literatura, son múltiples los artículos que asocian la dermatitis atópica con la EVK. Pero estas dos patologías no siempre vienen de la mano, por lo que su diagnóstico en ocasiones puede suponer todo un reto para el pediatra. Presentamos una actualización de los conocimientos de esta enfermedad a raíz de un caso recientemente diagnosticado en nuestro servicio


The variceliform eruption of Kaposi (EVK) is the cutaneous dissemination of the herpes simplex virus (HSV), the most frequent etiology being HSV type 1. It usually occurs in patients with underlying skin diseases or due to a lesion in the epidermal barrier. Clinical suspicion is confirmed by polymerase chain reaction, virus isolation in culture or by monoclonal antibodies made from a sample of skin lesions. The most frequent complication is bacterial superinfection due to Staphylococcus aureus and the treatment of choice is oral or intravenous acyclovir, depending on the severity. In literature, there are many articles that associate atopic dermatitis with the EVK. But these two pathologies do not always come hand in hand, so their diagnosis can sometimes be a challenge for the pediatrician. We present an update on the knowledge of this disease following a case recently diagnosed in our service

RESUMO

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

RESUMO

Introduction and objectives: Preschool-aged group is frequently affected by urticaria, and infections are the most frequently documented factors that cause acute urticaria in children. This prospective study was designed to investigate the underlying factors of acute urticaria in under five-year-old children and to describe predictive factors for progression to chronicity or recurrence after the first attack. Patients and methods: Children younger than five years of age with acute urticaria were recruited between July 2015 and July 2016. Patients (n = 83) were grouped into those below and above two years of age. In order to assess the risk factors for progression to chronicity or recurrence, logistic regression analysis was performed. Results: Upper respiratory tract infection was the most common detectable reason for acute urticaria (49.4%). Herpes Simplex Virus type 1 was significantly isolated in the cases with the manifestation of an acute single-episode urticaria (p = 0.042). Angioedema and food allergy were predominantly observed under two years old (p = 0.001, p = 0.006 respectively). A positive relationship was determined between the duration of urticaria and chronicity (r = 0.301, p = 0.006). The absence of atopic dermatitis (OR: 6.95, 95% CI: 1.35-35.67, p = 0.020), negative Herpes virus serology (OR: 4.25, 95% CI: 0.83-21.56, p = 0.040), and unknown etiology (OR: 3.30, 95% CI: 1.12-9.71, p = 0.030) were the independent risk factors for recurrent urticaria. Conclusions: Preschool-aged children with acute urticaria should be evaluated for infections at the time of admission. Patients with unknown etiology, negative Herpes virus serology, absence of atopic dermatitis, and long lasting urticaria should be followed up for chronicity and recurrence

RESUMO

BACKGROUND: It has been estimated that 15%-20% of human tumours are driven by infection and inflammation, and viral infections play an important role in malignant transformation. The evidence that herpes simplex virus type 1 (HSV-1) could be involved in the aetiology of oral cancer varies from weak to persuasive. This study aimed to investigate by nested PCR (NPCR) the prevalence of HSV-1 in samples from normal oral mucosa, oral leukoplakia, and oral squamous cell carcinoma (OSCC). MATERIAL AND METHODS: We investigated the prevalence of HSV-1 in biopsies obtained from 26 fresh, normal oral mucosa from healthy volunteers as well as 53 oral leukoplakia and 27 OSCC paraffin-embedded samples. DNA was extracted from the specimens and investigated for the presence of HSV-1 by nested polymerase chain reaction (NPCR) and DNA sequencing. RESULTS: HSV-1 was detected in 14 (54%) of the healthy samples, in 19 (36%) of the oral leukoplakia samples, and in 14 (52%) of the OSCC samples. The differences were not statistically significant. CONCLUSIONS: We observed a high incidence of HSV-1 in healthy oral mucosa, oral leukoplakia, and OSCC tissues. Thus, no connection between OSCC development and presence of HSV-1 was detected

RESUMO

Introducción. Los herpesvirus son una causa frecuente y tratable de infecciones mucocutáneas en la población pediátrica; su rápido diagnóstico puede ser importante para el manejo de cierto tipo de pacientes. Objetivos. Evaluar de forma prospectiva la eficacia de la inmunofluorescenica directa (IFD) frente al cultivo celular Shell vial en la detección de los herpesviurs tipo 1 y 2 y el virus varicela zoster en lesiones mucocutáneas pediátricas. Material y métodos. Las diferentes muestras fueron remitidas al laboratorio en un medio de transporte líquido para virus. Para la IFD se tomaron 200µ de la muestra y fueron citocentrigugados en 3 portas a 700 rpm durante 10 min. Después de su secado fueron fijados con acetona a 20ºC durante 10 min y luego teñidos con anticuerpos monoclonales específicos frente al VHS-1, VHS-2 y VVZ, siguiendo las recomendaciones del fabricante. Las muestras fueron consideradas adecuadas para la IFD si presentaban un mínimo de 20 células por porta. Las muestras fueron además inoculadas en Shell vials de las líneas celulares Vero y MRC-5 para el aislamiento viral. Los viales fueron incubados a 36º C y luego teñidos con los mismos anticuerpos monoclonales utilizados en la IFD. Resultados. A lo largo del estudio se analizaron 234 muestras cutáneas; 186 (79,4%) fueron consideradas como adecuadas. De ellas la IFD fue positiva en 69 (37,1%) muestras y el cultivo Shell vial en 57 (30,6%) muestras. La IFD detectó el VHS-1 en 41 muestras (59,4%) y el VVZ en 28 muestras (40,6%). El cultivo Shell vial fue positivo para el VHS-1 en 38 muestras (66,6%), para el VHS-2 en 1 muestra (1,7%) y para el VVZ en 18 muestras (31,5%). Utilizando la IFD como método de referencia el cultivo Shell vial presentó una sensibilidad global del 92,6% para el VHS-1 y del 64,2% para el VVZ. El tiempo de respuesta medio para el aislamiento del VHS-1 fue de 1,7 días y de 4.5 días para el VVZ. El tiempo de respuesta de la IFD para ambos virus fue de 2,7 horas. Conclusiones. La IFD es una técnica sensible, rápida y sencilla que ha mostrado ser una buena alternativa al cultivo Shell vial en la detección de las infecciones mucocutáneas causadas por los herpesvirus en la población pediátrica (AU)


Introduction. The herpetic infections are common and treatable causes of mucocutaneous infections in children and the rapid diagnosis is important for patient management. Objectives. To prospectively evaluate the efficacy of a direct immunofluorescence assay (DFA) versus the shell-vial culture in the detection of herpesvirus 1 and 2 (HSV-1 and HSV-2) and varizellazoster virus (VZV) in pediatric skin infections. Material and Methods. The different skin samples were send to the virology laboratory in a virus liquid transport medium. For performance of the DFA, 200µ per slide, were cytocentrifuged on 3 slides at 700 rpm for 10 min. After air drying the slides were fixed with acetone at -20ºC for 10 min, and then stained with fluorescein-labeled mouse monoclonal antibodies to HSV-1 and HSV-2 and to VZV following manufacturer´s instructions. The sample was considered adequate for the DFA if the total number of epithelial cells present was >25 per slide. The samples were inoculated into shell-vials of the Vero and MRC-5 cell lines. The vial were incubated at 36º and stained with the same monoclonal antibodies used in the DFA. Results. In the study period we analyzed 234 skin samples. 186 (79,4%) were considered adequate. Of them the DFA was positive in 69 (37,1%) samples and the shell-vial culture in 57 (30,6%) samples. The DFA detected the HSV-1 in 41 (59,4%) samples, and the VZV in 28 (40,6%). The shell-vial culture was positive for HSV-1 in 38 (66,6%) samples, for HSV-2 in 1 (1.7%), and for VZV in 18 (31.5%). Using the DFA as a reference method, the shell-vial culture has an overall sensitivity of 92,6% for the HSV-1 and 64,2% for VZV. The turnaround time for the herpesvirus isolation in the shell-vial culture was 1.7 days for HSV-1, and 4.5 days for VZV. The turnaround time for the DFA was 2.7 hours. Conclusion. The DFA is a sensitive, rapid and easy alternative to the shell-vial culture in the detection of herpesvirus in pediatric skin samples (AU)

RESUMO

Frecuentemente en pacientes Sida las lesiones bucales son de difícil diagnóstico. Nuestro objetivo es actualizar la etiofisiopatogenia de lesiones producidas por herpes virus como una manifestación del síndrome de reconstitución inmune, en mucosa bucal y presentar un paciente inmuno suprimido con lesiones difícilmente diagnosticables de herpes virus simple 1/2.Caso clínico. Paciente masculino, 39 años, homosexual, antecedentes de HZV, TBC y ETS. CMV, hepatitis B y Toxoplasmosis negativas y hepatoesplenomegalia, fibrosis granulomatosa peritoneal y adenopatías mesentéricas activas; 12 CD4 y 5,54 log. de carga viral. Se instaló TARV con buena respuesta. Al mes presentó dificultad para hablar, hipersalia, dolor, y lesiones exofíticas en lengua, aspecto rizado, irregular, con surcos, erosiones, úlceras, y pápulas, cubiertas por pseudomembrana amarillenta. Los cultivos resultaron negativos para hongos, bacterias o parásitos. Sucesivas biopsias analizadas por cinco patólogos descartaron malignidad o autoinmunidad. Diagnósticos similares refirieron “reacción inflamatoria crónica”. Un sexto experto por detalles histológicos e inmunomarcación con antisuero HSV-I/HSV-II reveló positividad nuclear y citoplasmática Epifluorescencia y microscopía electrónica certificaron el diagnóstico. El Acyclovir 4g/diarios, 4 semanas fue eficaz. Conclusión. la infección por Herpes virus en pacientes con inmunosupresión severa complica el diagnóstico clínico, por lo cual conviene agotar la búsqueda (AU)


Frequently on Aids patients, oral lesions are difficult to diagnose. Our objective is to actualize the etiopathogenie of Herpes virus infection, especially on oral mucosa and to present an immunosupressed patient with atypical oral tonge´s lesions of Herpes virus.

RESUMO

Introducción: Actualmente, existe debate sobre la posibilidad de «infección»/interacción de los espermatozoides con diferentes virus, inclusive para algunos virus se intentan dilucidar mecanismos y receptores que podrían estar involucrados en esta interacción. Adicionalmente, se ha reportado la presencia de algunos genomas virales en el DNA espermático, planteando la posibilidad de transmitir la infección a la pareja y a la descendencia. Objetivo: En la presente revisión se pretende describir los mecanismos de infección de algunos virus a las fracciones seminales, pretendiendo mediante una revisión bibliográfica, responder a la pregunta ¿cómo los virus de transmisión sexual infectan al semen?. Materiales y métodos: Se realizo una búsqueda bibliográfica sobre la interacción de virus y espermatozoides. Resultados: Algunos virus pueden interactuar con los espermatozoides y estos podrían transferir el virus a la descendencia; sin embargo, en la mayoría de los casos, los receptores que permiten esta interacción no están claramente descritos. Conclusiones: A pesar de la información actual, nuevos estudios experimentales son necesarios para determinar el papel de los espermatozoides en la diseminación de la infecciones de transmisión sexual (AU)


Introduction: The possible “infection”/interaction processes between sperm and different microorganisms are being under discussion nowadays. This process might include some viruses and even recent investigations are aiming to elucidate the mechanisms and the receptors that may be involved in this interaction. Furthermore, it has been reported the presence of some viral genomes within the sperm DNA, raising the possibility of transmitting the infection to the partner and offspring. Objective: The aim of this review is to describe the mechanisms by how viruses could possibly infect some seminal fractions. This is pursued by performing a literature review for answering the question: how the sexually transmitted virus could be infecting sperm?. Materials and methods: We carried out a bibliographic review about sperm and virus interaction. Results_ Some viruses interact with sperm cells; and sperm cells could transfer the viruses to offspring, however, in most cases, the receptors that allow this interaction are not clearly described. Conclusions: Based on the current information, new in vitro studies are needed to determine the role of sperm in spreading viruses of sexually transmitted infections (AU)

RESUMO

La encefalitis aguda es una emergencia médica de etiología variada, aunque en su mayoría es viral. Un porcentaje elevado queda sin un diagnóstico etiológico específico debido al gran número de agentes causales. La causa más frecuente de encefalitis esporádica en todo el mundo es el virus del herpes simple tipo 1, aunque en determinadas localizaciones es importante considerar determinados agentes locales, como el virus del Nilo Occidental o la encefalitis transmitida por garrapata, entre otros. Los pacientes con encefalitis requieren cuidados generales, con especial énfasis en los problemas respiratorios derivados del deterioro del nivel de consciencia, las crisis epilépticas y la hipertensión intracraneal secundaria al edema cerebral. La encefalitis herpética tiene una incidencia de 4 casos por millón de habitantes. La presentación clínica junto al EEG, la RM y el análisis del LCR son claves en su diagnóstico. La PCR en el LCR es altamente sensible y específica (> 95%), aunque puede ser negativa en los primeros 3 días de enfermedad. El tratamiento de elección en la actualidad es el aciclovir intravenoso, a una dosis de 10 mg/kg/8 h, durante 10-21 días. En casos de resistencia, el foscarnet es una alternativa. Los arbovirus constituyen otro importante grupo etiológico en las encefalitis. Son zoonosis transmitidas por mosquitos o garrapatas e incluyen los alfa-virus, los bunyavirus (el virus de la Toscana y otros) y los flavivirus. Entre estos últimos destaca el virus del Nilo Occidental. No hay tratamiento específico y el diagnóstico se basa en la serología o la PCR dependiendo del tipo de virus (AU)


Acute encephalitis can be due to many causes, although most are viral, and is a medical emergency. A significant percentage remains without a definitive diagnosis due to the large number of etiologic agents. The single most frequent cause of sporadic encephalitis around the world is herpes simplex virus type 1, although in certain locations diverse local agents should be considered such as West Nile virus or tick-borne encephalitis, among others. Patients with encephalitis require intense care measures with special emphasis on respiratory problems secondary to a depressed level of consciousness, seizures, and intracranial hypertension due to cerebral edema. Herpes encephalitis has an incidence of 4 cases per million inhabitants. Clinical presentation, together with electroencephalography, magnetic resonance imaging and cerebrospinal fluid (CSF) findings are critical to establish a diagnosis. Polymerase chain reaction (PCR) in CSF is highly sensitive and specific (> 95%), but the results can be negative during the first 3 days of the disease. The treatment of choice is currently acyclovir 10 mg/kg/8 h for 10-21 days. Whenever resistance is suspected, foscarnet is an alternative. The family of arboviruses represents another important etiologic group of encephalities. These are zoonotic diseases transmitted by mosquitoes or ticks and include alphaviruses, bunyaviruses (Toscana virus and others) and flaviviruses. The West Nile virus belongs to the latter group. There is no specific therapy and diagnosis is based on serology and PCR depending on the suspected virus (AU)

RESUMO

Tras una encefalitis herpética (EH), una cuarta parte de los pacientes con EH tiene una recaída de la enfermedad que, excepcionalmente, se manifiesta como un síndrome extrapiramidal de tipo coreoatetósico. La base fisiopatológica de este tipo de recaída es desconocida, pero se hipotetiza que puede ser un cuadro inmunitario mediado. Se presenta el caso de un niño de 8 meses con EH por virus del herpes simple tipo 1 que en la tercera semana de evolución tuvo una recaída caracterizada por un síndrome extrapiramidal con coreoatetosis y balismo. El cuadro se interpretó como postinfeccioso, inmunitario mediado. Se trató al paciente con corticoides en altas dosis e inmunoglobulinas, además de un nuevo ciclo de aciclovir. La coreoatetosis fue tan grave y resistente a los fármacos que obligó a sedorrelajar al paciente inicialmente. Posteriormente, se ensayó tratamiento con tetrabenazina. Se estudió a escala molecular una mutación en el receptor tipo Toll 3, que se ha relacionado con la susceptibilidad de presentar la enfermedad, que resultó ser negativa (AU)


After Herpes simplex encephalitis, 25% of cases may have a relapse, rarely as a choreoathetosic movement disorder. The anatomic basis for herpes simplex virus encephalitis-associated movement disorders remains poorly understood, but the hypothesis is that it may be due to a post-infectious immune-mediated process. We report an 8-month-old boy, with herpes simplex encephalitis type 1, who started with an extrapyramidal Syndrome, presenting with choreoathetosis and ballistic movements, three weeks after onset. These new symptoms were attributed to a post-infectious immune-mediated process. We treated our patient with corticosteroids at high dose and gamma-globulins, in addition to a new course of Acyclovir. Sedation was required to control the intense choreoathetosic movements. Tetrabenazine was also tried, unsuccessfully. We studied a mutation on the toll like receptors (TLR3), which has been related to susceptibility for the disease, which was negative (AU)

RESUMO

Introduction: This study was designed to investigate the effect of oral HSV-1 shedding on the survival of allogeneichematopoietic stem cell transplanted (allo-HSCT) patients.Methods: One hundred nineteen allo-HSCT patients were included in the study and divided in three groups: beforetransplant, 100 days after transplant and 1 year of allo-HSCT. Healthy volunteers matched by age and genderwere also selected. Oral swabs were performed and the nested PCR was used to detect HSV-1 presence in the oralmucosa. In statistical analysis, chi-square test was used to test the distribution of HSV1 shedding among the threegroups. Time to death after allo-HSCT was displayed by means of the Kaplan-Meier method and the results werecompared by the log-rank test. Cox proportional hazards multivariate model was used to evaluate the survival.Results: We observed that HSV-1 shedding was similar at different points after allo-HSCT. However, HSV-1 sheddingbefore allo-HSCT was associated with worst survival rates after allo-HSCT in multivariate analysis.Conclusion: Our data demonstrates that HSV-1 shedding in oral mucosa before transplant is associated with worstsurvival rate of allo-HSCT patients (AU)
