Contexto: As reações hansênicas são episódios inflamatórios agudos imunomediados que podem ocorrer em indivíduos com hanseníase. Lesões atípicas de eritema nodoso hansênico (ENH) são raras e podem se apresentar como pústulas, bolhas, necrose, úlceras e, eventualmente, podem simular outras doenças como a síndrome de Sweet e eritema multiforme. Descrição do caso: Paciente do sexo masculino, 24 anos de idade, com diagnóstico prévio de hanseníase virchowiana e realização de tratamento adequado, com término da poliquimioterapia quatro anos antes de comparecer ao nosso serviço quando foi avaliado, apresentando pequenas vesículas translúcidas agrupadas sobre uma base eritematosa e áreas com crostas necróticas, simulando lesões herpéticas, na porção superior das costas, parte inferior do pescoço e haste do pênis. O exame histopatológico da biópsia cutânea foi sugestivo de reação tipo 2 e o tratamento com talidomida foi satisfatório. Discussão: As reações na hanseníase representam episódios de hipersensibilidade aguda a antígenos de Mycobacterium leprae e podem se desenvolver antes, durante ou após o término do tratamento. Acredita-se que o ENH, ou reações do tipo 2, ocorram devido à deposição de imunocomplexos em múltiplos órgãos em pacientes que apresentam a forma multibacilar. Conclusões: As reações hansênicas são desafios no manejo da hanseníase, especialmente pelo fato de a maioria das sequelas permanentes ser secundária a esses episódios inflamatórios agudos. O conhecimento das possíveis apresentações atípicas das reações hansênicas é fundamental para o diagnóstico precoce e o tratamento adequado, a fim de prevenir morbidade grave relacionada à hanseníase.

Abstract A 56-year-old male, HIV-positive, presented with a 3-day history of multiple indurated erythematous nodules with superficial and well-defined erosions on his right gluteus. Skin biopsy showed ballooning-necrotic keratinocytes and cultures were positive for herpes simplex 2. Genital herpes simplex infection recurrences may not be restricted to the anterior part of the genitalia and clinical presentation in the lumbar area or gluteus must be differentiated from varicella-zoster virus infection. Tumor-like presentation is a very rare manifestation of HSV cutaneous infection. It is important to take this morphological variant into consideration not to delay the diagnosis of a viral infection, especially in an immunosuppressed patient.

In this study, emotional stress-induced herpes simplex virus type 1(HSV-1) susceptibility model was employed to simu-late the pathological state of " depression-induced liver fire", and the protection effect of Qingre Xiaoyanning(QX) in clearing liver fire was investigated. BALB/c mice were randomly divided into a normal group, a HSV-1 group, a restraint stress + HSV-1 group,low-(0. 658 g·kg~(-1)) and high-dose(1. 316 g·kg~(-1)) QX groups, and an acyclovir group. Except for the normal group and the HSV-1 group, the mice in other groups received daily restraint stress for 6 h from day 3 of medication. On day 9 of medication, mice were anesthetized by isoflurane and infected intranasally with HSV-1. Survival rate, weight change, encephalitis symptoms, and eye injury of mice were recorded for 14 d after virus infection. Hematoxylin-eosin(HE) staining and immunohistochemical staining were used to detect pathological changes and HSV-1 antigen distribution. Plaque assay was performed to detect the titer of HSV-1. The protein ex-pression of ICP27 in the mouse brain was detected by Western blot. The experimental results showed that QX could increase the survival rate of HSV-1-infected mice loaded with emotional stress(P<0. 001), reduce the titer of HSV-1 in the mouse brain(P<0. 01), relieve brain inflammation(P<0. 05) and eye injury(P<0. 05), down-regulate the expression of ICP27 related to HSV-1(P<0. 05), and decrease the distribution of HSV-1 antigen in the mouse brain. The results demonstrated that QX significantly reduced the susceptibility to HSV-1 induced by emotional stress, which is expected to provide a theoretical basis for the treatment and preven-tion of HSV-1 infection and promote the clinical development and application of Chinese medicine effective in clearing liver fire.

La erupción variceliforme de Kaposi es una infección cutánea diseminada, causada en la mayor parte de los casos por el virus Herpes simple tipo 1. Se suele presentar en pacientes con alteraciones preexistentes de la barrera cutánea, especialmente en niños con dermatitis atópica. Se comunica el caso de un paciente de 84 años, quien negaba enfermedades cutáneas previas, que consultó por lesiones dolorosas y pruriginosas, en la piel del tórax y el abdomen, de 3 semanas de evolución. Con sospecha de una enfermedad infecciosa viral, bacteriana, ampollar o neutrofílica, se realizó inmunofluorescencia directa para herpes, cultivo y biopsia de piel para estudio histológico. La inmunofluorescencia fue positiva para Herpes simple tipo 1 y el estudio histopatológico mostró cambios compatibles con infección herpética y enfermedad de Darier. La enfermedad de Darier es una genodermatosis infrecuente que se suele manifestar en la adolescencia. Si bien su diagnóstico en la ancianidad es excepcional, este caso ilustra que se debe considerar en todos los pacientes que presenten erupción variceliforme. (AU)

Kaposi's varicelliform rash is a disseminated cutaneous infection, caused by Herpes virus 1. It usually presents in patients with pre-existing skin barrier disorders, especially in children with atopic dermatitis. We report the case of an 84-year-old patient, who reported having no previous skin diseases, who consulted for painful, itchy, 3-week-old skin lesions. As we suspected viral, bacterial, bullous or neutrophilic disease, direct immunofluorescence, culture, and skin biopsy for histological study were performed. Immunofluorescence was positive for Herpes simplex type 1 and the histopathological study showed changes compatible with herpetic infection and Darier's disease. Darier's disease is a rare genodermatosis that usually manifests in adolescence. Although its diagnosis in old age is anecdotal, it should be considered in patients with a varicelliform rash. (AU)

Bovine alphaherpesvirus 2 (BoHV-2) is the agent of herpetic mammilitis (BHM), a cutaneous and self-limiting disease affecting the udder and teats of cows. The pathogenesis of BoHV-2 is pourly understood, hampering the development of therapeutic drugs, vaccines and other control measures. This study investigated the pathogenesis of BoHV-2 in calves after inoculation through different routes. Three- to four-months seronegative calves were inoculated with BoHV-2 (107TCID50.mL-1) intramuscular (IM, n=4), intravenous (IV, n=4) or transdermal (TD) after mild scarification (n=4) and submitted to virological, clinical and serological monitoring. Calves inoculated by the IV route presented as light increase in body temperature between days 6 to 9 post-inoculation (pi). Virus inoculation by the TD route resulted in mild inflammatory lesions at the sites of inoculation, characterized by hyperemia, small vesicles, mild exudation and scab formation, between days 2 and 8pi. Virus or viral DNA was detected by PCR in the crusts/swabs collected from lesions of 3 out of 4 animals inoculated TD from day 2 to 8pi. Viremia was detected in 3/4 animals of the IM group (from day 4 to 8pi); in 2/4 animals of the IV group (days 6 and 8pi) but not in the TD group. Calves from all inoculated groups seroconverted to BoHV-2 in titers from 4 to 64, as indicated by virus-neutralizing (VN) assays performed in sera collected at day 15pi. Administration of dexamethasone (Dex) to the inoculated calves at day 48pi, did not result in virus reactivation as indicated by lack of virus detection in the blood and/or in inoculation sites and no increase in VN antibody titers. These results demonstrated that BoHV-2 was able to replicate efficiently in calves following different routes of exposure, produced viremia after IM and IV inoculation and was not reactivated by Dex treatment.(AU)

O alfaherpesvírus bovino 2 (BoHV-2) é um agente etiológico da mamilite herpética (BHM), uma doença cutânea e autolimitante do úbere e tetos de vacas. Pouco se sabe sobre a patogênese do BoHV-2, dificultando o desenvolvimento de medicamentos terapêuticos e vacinas. Este estudo investigou a patogênese do BoHV-2 em bezerros após a inoculação por diferentes vias. Bezerros soronegativos de três a quatro meses foram inoculados com BoHV-2 (107TCID50.mL-1) por via intramuscular (IM, n=4), por via intravenosa (IV, n=4) ou transdérmica (TD, n=4) após escarificação leve e submetidos a monitoramento virológico, clínico e sorológico. Os bezerros inoculados pela via IV apresentaram aumento leve da temperatura corporal entre os dias 6 a 9 pós-inoculação (pi). A inoculação do vírus pela via TD resultou em lesões inflamatórias leves nos locais de inoculação, caracterizadas por hiperemia, pequenas vesículas, exsudação leve e formação de crostas, entre os dias 2 e 8pi. O vírus ou DNA viral foi detectado por PCR nas crostas/swabs coletados de lesões de 3 de 4 animais inoculados TD do dia 2 ao 8pi. Viremia foi detectada em 3/4 dos animais do grupo IM (do dia 4 ao 8pi); em 2/4 animais do grupo IV (dias 6 e 8pi), mas não no grupo TD. Bezerros de todos os grupos inoculados soroconverteram o BoHV-2 em títulos de 4 a 64, conforme indicado por ensaios de vírus-neutralização (VN) realizados em soro coletado no dia 15pi. Administração de dexametasona (Dex) nos bezerros inoculados no dia 48pi, não resultou em reativação do vírus, como indicado pela falta de detecção de vírus no sangue e/ou nos locais de inoculação e pela ausência de aumento nos títulos de anticorpos. Estes resultados demonstraram que o BoHV-2 foi capaz de replicar eficientemente em bezerros seguindo diferentes vias de inoculação, produziu viremia após a inoculação IM e IV e não foi reativado pelo tratamento com Dex.(AU)

Abstract Herpes simplex virus (HSV) is a cause of a severe disease of the central nervous system (CNS) in humans. The demonstration of specific antibodies in the cerebrospinal fluid (CSF) may contribute to the retrospective neurological diagnosis. However, the commercial immunological tests for HSV infection are for use in serum samples. Objective: The aim of the present study was to adapt a commercial kit anti-HSV IgG used for serum samples to be performed with a CSF sample. Methods: Forty CSF specimens from 38 patients with suspected CNS HSV infection were serially diluted for detecting anti-HSV IgG by enzyme immunoassay (EIA). The same samples were also analyzed with the polymerase chain reaction (PCR). Results: The sensitivity of EIA test for HSV was 5% (dilution 1:40) and 65% (dilution 1:2) in CSF, and HSV DNA PCR was 15%. The combined analysis of EIA (dilution 1:2) and PCR increased the sensitivity up to 72.5%. The inflammatory CSF was associated with positive HSV PCR. Conclusions: We demonstrated the importance to adapt serological anti-HSV IgG EIA test for CSF assays to increase the accuracy of the analysis, considering the low concentration of specific antibodies in CSF.

Resumo O vírus herpes simples (HSV) é um dos agentes causadores de uma doença grave no sistema nervoso central (SNC) em humanos. A detecção de anticorpos específicos no líquido cefalorraquidiano (LCR) pode contribuir para o diagnóstico neurológico retrospectivo. Entretanto, os testes imunológicos comerciais são para uso em amostras de soro. Objetivo: Adaptar um kit comercial sorológico anti-HSV IgG para ser utilizado no de LCR. Metodos: Quarenta amostras de LCR de 38 pacientes com suspeita de infecção por HSV no SNC foram diluídas pesquisa de anticorpos anti-HSV IgG pelo método imunoenzimático (EIA). Além disso, as mesmas amostras também foram analisadas por reação em cadeia da polimerase (PCR). Resultados: A sensibilidade do teste EIA para o HSV consistiu em 5% (diluição 1:40) e 65% (diluição 1:2) no LCR, e o PCR do DNA do HSV, 15%. A análise combinada de EIA (diluição 1:2) e PCR aumentou a sensibilidade para 72,5%. Houve associação entre presença do LCR inflamatório e PCR positiva para HSV. Conclusões: Demonstramos a importância na adaptação previa do teste sorológico anti-HSV IgG EIA para ensaios do no LCR, a fim de aumentar a acuracia da análise, considerando a baixa concentração de anticorpos específicos no LCR.

Abstract Objective Estimate the prevalence of human herpesvirus type 1 HSV-1 DNA in placental samples, its incidence in umbilical cord blood of newborns and the associated risk factors. Methods Placental biopsies and umbilical cord blood were analyzed, totaling 480 samples, from asymptomatic parturients and their newborns at a University Hospital. Nested polymerase chain reaction (PCR) and gene sequencingwere used to identify the virus; odds ratio (OR) and relative risk (RR) were performed to compare risk factors associated with this condition. Results The prevalence of HSV-1 DNA in placental samples was 37.5%, and the incidence in cord blood was 27.5%. Hematogenous transplacental route was identified in 61.4% from HSV-1+ samples of umbilical cord blood paired with the placental tissue. No evidence of the virus was observed in the remaining 38.6% of placental tissues, suggesting an ascendant infection from the genital tract, without replication in the placental tissue, resulting in intra-amniotic infection and vertical transmission, seen by the virus in the cord blood. The lack of condom use increased the risk of finding HSV-1 in the placenta and umbilical cord blood. Conclusion The occurrence of HSV-1 DNA in the placenta and in cord blood found suggests vertical transmission from asymptomatic pregnant women to the fetus.

Resumo Objetivo Estimar a prevalência do DNA do vírus herpes humano 1 (HSV-1) em amostras de placenta, sua incidência no sangue do cordão umbilical de recém-nascidos e fatores de risco associados. Métodos Biópsias de placenta e de sangue de cordão umbilical foram analisadas, totalizando 480 amostras de parturientes assintomáticas e seus recém-nascidos emum hospital universitário. Reação de cadeia de polimerase (RCP) nested e sequenciamento gênico foram usados para identificar o vírus; odds ratio (OR) e risco relativo (RR) foram realizados para comparar os fatores de risco associados à essa condição. Resultados A prevalência do DNA do HSV-1 em amostras de placenta foi de 37,5%, e a incidência no sangue do cordão foi de 27,5%. A via transplacentária hematogênica foi identificada em 61,4% das amostras de HSV-1+do sangue do cordão umbilical, pareadas com o tecido placentário. Nenhuma evidência do vírus foi observada nos restantes 38,6% dos tecidos placentários, sugerindo uma infecção ascendente do trato genital. A falta de uso do preservativo aumentou o risco de encontrar o HSV-1 na placenta e no sangue do cordão umbilical. Conclusão A ocorrência de DNA do HSV-1 na placenta e no sangue do cordão umbilical sugere uma transmissão vertical de gestantes assintomáticas para o feto.

La inflamación del sistema nervioso central secundaria a la infección por la familia herpesviridae puede generar un compromiso difuso del parénquima encefálico, la cual puede ser fatal en ausencia de un rápido diagnóstico y tratamiento. Objetivo: revisar las diferentes características biológicas, fisiopatológicas, clínicas, terapéuticas y pronóstico del meningoencefalitis causada por VHS-1 y 2. Materiales y métodos: revisión de la literatura científica (revisión crítica), llevada a cabo mediante las bases de datos Medline y buscadores específicos IMBIOMED, PUBMEDE, SCIENCEDIRECT, SCIELO, con un total de 150 artículos, se priorizaron 67 los cuales fueron leídos a profundidad. Resultados y discusión: debido el neurotropismo del herpes virus simple puede causar neuroinvasividad, neurotoxicidad y latencia en el SNC. Por sus características semiológicas inespecíficas se requiere un estudio exhaustivo para lograr el diagnóstico acertado. Los métodos actuales tales como neuroimágenes y PCR han aportado al esclarecimiento del diagnóstico etiológico de esta patología. La detección temprana de la entidad y la instauración precoz del tratamiento, se asocian con un aumento en la tasa de supervivencia y a una disminución de las secuelas neurológicas. Conclusión: conocer la biología del virus, su comportamiento, las características clínicas y el tratamiento de la entidad es una estrategia eficaz para disminuir secuelas y desenlaces fatales.

Central nervous system (CNS) inflammation secondary to an infection by the Herpesviridae family may generate a diffuse compromise of the encephalic parenchyma which may be fatal in the absence of a rapid diagnosis and prompt institution of treatment. Objective: to review the biological, physiopathology, clinical and therapeutic characteristics and prognosis of encephalitis caused by HSV-1 and HSV-2 viruses. Materials and Methods: a scientific literature review (critical review), in the Medline scientific database and IMBIOMED, PUBMEDE, SCIENCEDIRECT, SCIELO search engines, obtaining 150 results limited to 67 articles read in detail. Results and Discussion: herpes simplex virus is neurotropic and may cause invasion, toxicity and latent infection of the CNS. Due to its unspecific symptoms a thorough diagnostic workup is required to achieve a correct diagnosis. Current methods such as neuroimaging studies and polymerase chain reaction (PCR) examination have contributed to elucidate the etiologic virus. A rapid detection and prompt treatment is associated with an increase in the survival rate and decrease in neurologic sequelae. Conclusion: understanding the biology, behavior, clinical manifestations and treatment of this viral infection is an efficient strategy to prevent sequelae and reduce fatal outcomes.

La meningitis linfocítica recurrente o meningitis de Mollaret es una entidad asociada a un gran número de etiologías infecciosas, autoinmunes, toxicológicas y neoplásicas. En la actualidad el virus herpes simple tipo 2 (HSV-2) es el agente más frecuentemente aislado. Afecta frecuentemente a mujeres de mediana edad y tiende a autolimitarse sin secuelas dentro de la primera semana de inicio de síntomas. El diagnóstico se basa en la detección de ácidos nucleicos virales en el líquido cefalorraquídeo. Al momento no se ha demostrado beneficio en el uso de tratamiento antiviral en la prevención de recurrencias.

Recurrent lymphocytic meningitis or Mollaret´s meningitis is a rare condition caused by a number of infectious, autoimmune, toxic and neoplastic diseases. Herpes simplex type 2 is the most commonly isolated agent. It usually compromises middle aged women, with a self-limited clinical presentation that resolves within a week leaving no sequelae. Its diagnosis is mainly based on nucleic acid detection on cerebrospinal fluid. Antiviral prophylaxis has not shown conclusive to avoid recurrences.

A meningite recorrente linfocítica benigna ou meningite de Mollaret, inicialmente descrita pelo neurologista francês Pierre Mollaret em 1944, é uma condição relativamente rara, benigna mas incapacitante durante os seus períodos de agudização. Trata-se de quadro inflamatório meníngeo recorrente devido a reativação de infecção pelo herpes simples vírus, particularmente o herpesvirus do tipo 2 (HSV-2). Pode ser reconhecida a partir do seu quadro clínico de meningismo agudo, perfil liquórico linfocítico e identificação do genoma viral por PCR no líquor. Aciclovir e seus derivados podem ser utilizado no seu tratamento ou na sua profilaxia. Sua identificação é importante no sentido de se excluir outras causas de quadros meníngeos recorrentes.

Benign recurrent lymphocytic meningitis or Mollaret's meningitis (MM) was frst described by the French neurologist Pierre Mollaret in 1944. MM is a relatively rare, benign but disabling condition. MM is a recurrent meningeal inflammatory illness due to reactivation of herpes simplex virus infection, particularly herpesvirus type 2 (HSV-2). It can be recognized from its clinical picture of acute meningism, lymphocytic CSF profle and by the identifcation of the viral genome in the CSF by PCR. Acyclovir and its derivatives may be used for its treatment or prophylaxis. The identifcation of MM is important in order to exclude other causes of recurrent meningeal conditions.

Resumen Las lesiones anogenitales hipertróficas, pseudotumorales y similares a placas, son presentaciones atípicas del virus herpes simple (VHS). Estas lesiones desarrollan resistencia a los tratamientos y se presentan en inmunocomprometidos, especialmente aquellos con infección por el virus de inmunodeficiencia humana (VIH). Presentamos el caso de un paciente masculino de 38 años de edad, VIH/SIDA, con antecedente de carcinoma escamocelular infiltrante de canal anal, con lesiones múltiples hipertróficas anogenitales y exudativas, a quien se le confirma infección por VHS-1, sin respuesta a aciclovir ni valaciclovir a dosis óptimas, el cual resuelve con 21 días de foscarnet intravenoso. Nuestro caso muestra la importancia de considerar el uso de foscarnet en adultos con infección de VIH y del VHS, que no respondan a tratamiento de primera línea, en un país donde no hay esquemas establecidos de manejo para este tipo de presentaciones y donde existe la limitante de no haber disponibilidad en pruebas para resistencia a antivirales.

Abstract Pseudotumoral, hypertrophic, plaque-like anogenital ulcers are atypical features of herpes simplex infection. These ulcers develop treatment resistance and they appear in immunocompromised mainly those infected by human immunodeficiency virus. We present a 38 years-old man with AIDS and personal history of infiltrative squamous carcinoma of anal canal with multiple hypertrophic and exudative ulcers secondary to VHS-1 etiology without response to acyclovir neither valacyclovir at optimal doses but complete answer with 21 days of foscarnet treatment. Our case highlights the role of foscarnet in adults with HIV-HSV coinfection that don't respond to frst line treatment in a country that doesn't have clear treatment recommendations in these cases and with the limitations of absence of antiviral resistance test.

El granuloma anular (GA) es una dermatosis inflamatoria granulomatosa, generalmente asintomática, con distintas formas de presentación clínica, que puede distribuirse de forma localizada o generalizada. su etiología es incierta pero se la ha vinculado a factores desencadenantes como traumatismos, fármacos, diabetes mellitus, tiroideopatías, neoplasias, infecciones virales (herpes simple y varicela zóster) y excepcionalmente puede aparecer en la misma localización donde previamente aconteció otra enfermedad con la cual no guarda relación alguna (fenómeno isotópico de Wolf). En su patogenia intervendrían mecanismos de hipersensibilidad retardada y de estrés oxidativo celular. Existen múltiples terapias con respuesta variable y se ha observado autorresolución en casi el 75% de los casos. Presentamos el caso de una mujer de 64 años de edad, hipotiroidea de larga data, con un granuloma anular generalizado que apareció sobre cicatrices residuales de un herpes zóster (fenómeno isotópico de Wolf) y su respuesta al tratamiento con Vitamina E por vía oral

Granuloma annulare (GA) is a granulomatous inflammatory dermatosis, usually asymptomatic, with different forms of clinical presentation, which can be localized or generalized. Its etiology is uncertain but has been linked to triggers such as trauma, drugs, diabetes mellitus, thyroid disease, neoplasms and viral infections (herpes simplex, varicella-zoster). Exceptionally, it may appear in the same location where another disease has previously occurred but with no relationship to it (Wolf isotopic response). In their pathogenesis, delayed hypersensitivity mechanisms and cellular oxidative stress would intervene. There are multiple therapies with variable response, and autorresolution has been observed in almost 75% of the cases. We present the case of a 64-year-old woman with a long history of hypothyroidism, with diagnosis of generalized granuloma annulare on residual scars of Herpes Zoster (Wolf 's isotopic response) and its response to oral Vitamin E.

Herpes simplex virus (HSV), including HSV-1 and HSV-2, is an important pathogen that can cause many diseases. Usually these diseases are recurrent and incurable. After lytic infection on the surface of peripheral mucosa, HSV can enter sensory neurons and establish latent infection during which viral replication ceases. Moreover, latent virus can re-enter the replication cycle by reactivation and return to peripheral tissues to start recurrent infection. This ability to escape host immune surveillance during latent infection and to spread during reactivation is a viral survival strategy and the fundamental reason why no drug can completely eradicate the virus at present. Although there are many studies on latency and reactivation of HSV, and much progress has been made, many specific mechanisms of the process remain obscure or even controversial due to the complexity of this process and the limitations of research models. This paper reviews the major results of research on HSV latency and reactivation, and discusses future research directions in this field.
