Características de recién nacidos hijos de madre con IgM positiva para el Virus Herpes Simplex

Introducción: El herpes connatal es una entidad infrecuente asociada a elevada morbimortalidad. La probabilidad de transmisión al recién nacido va de 5% al 85%. El diagnóstico se dificulta por falta de clínica, serología no confiable y por la no disponibilidad de PCR en los servicios públicos de países en vías de desarrollo. La IgM en gestantes podría ser utilizada como un marcador de sospecha para evaluar al neonato. Objetivo: Caracterizar a los recién nacidos, hijos de gestantes con IgM positiva para HVS 1-2 y la frecuencia de encefalitis en los infantes. Materiales y métodos : Estudio observacional, descriptivo, prospectivo, realizado de mayo de 2020 a octubre de 2021. Se incluyeron recién nacidos (RN) de madres con IgM positiva para Herpes Virus Simplex (HVS) a partir de la segunda mitad del embarazo. En el RN se realizó serología IgG e IgM, y además, PCR- RT para HVS 1-2 en sangre y/o LCR, excluyéndose los nacidos en otras maternidades y/o sin datos de serología materna. Resultados: 36 pacientes. Edad materna 28 años (DS + 4), 5% con antecedentes de HVS, 61% cesárea. 36% prematuros, 13% RCIU. Síntomas agudos en el RN 22%. De ellos, 19% plaquetopenia, 44% alteración de GOT. 63% PCR HVS en sangre y 44% en LCR. Se encontró hemorragia, hidrocefalia, leucomalacia en 27%. No se encontró diferencias en la expresión clínica por tipo de parto. Conclusiones: Los RN hijos de gestantes con IgM positiva para VHS desde la segunda mitad del embarazo o periparto, presentaron infección por VHS determinada por PCR en sangre o LCR, independiente de la vía del parto. El diagnóstico serológico en embarazadas permite la pesquisa, diagnóstico y tratamiento temprano del RN.

Introduction: neonatal herpes is a rare entity associated with high morbidity and mortality. The probability of transmission to the newborn ranges from 5% to 85%. The diagnosis is difficult due to the lack of clinical signs, unreliable serology and the non-availability of PCR in public services in developing countries. IgM in pregnant women could be used as a suspected marker to evaluate the neonate. Objective: To characterize newborn children of pregnant women with positive IgM for HSV 1-2 and the prevalence of encephalitis in infants. Materials and methods: Observational, descriptive, prospective study, carried out from May 2020 to October 2021. Newborns (NB) of mothers with positive IgM for Herpes Virus Simplex (HSV) from the second half of pregnancy were included. In newborns, IgG and IgM were performed, and in addition, PCR-RT for HSV 1-2 in blood and/or CSF, excluding those born in other hospitales and/or without maternal serology data. Results: We included 36 patients. Maternal age was 28 years (DS + 4), 5% with a history of HSV. 61% were delivered via cesarean section, 36% were premature, 13% had IUGR. 22% of the newborns had acute symptoms. 19% had thrombocytopenia, 44% had GOT alteration. 63% were PCR positive for HSV in serum and 44% were CSF-positive. Hemorrhage, hydrocephalus and leukomalacia were found in 27%. No differences were found in clinical expression by type of delivery. Conclusions: Newborns born to pregnant women with positive IgM for HSV from the second half of pregnancy or peripartum, presented HSV infection as determined by PCR in blood or CSF, regardless of the route of delivery. Serological diagnosis in pregnant women allows early screening, diagnosis and treatment of the NB.

Research progress on herpes simplex virus membrane fusion protein interactions / 中国生物制品学杂志

@#Herpes simplex virus(HSV)is a ubiquitous enveloped virus containing double-stranded DNA. HSV-1 infection can cause inflammation of the lips,conjunctivitis and encephalitis,HSV-2 infection can cause genital herpes at many ages,and both viruses can establish lifelong latent infection in the body. Membrane fusion triggered by the interaction of various HSV membrane proteins is an important way for viruses to enter host cells. This review introduced the conserved core fusion mechanism of HSV composed of four viral glycoproteins gD,gH,gL and gB by analyzing the structure of glycoproteins and their interaction modes. Since there is currently no HSV vaccine approved for marketing in the world,it is of great significance to study the mode of action of HSV and host cells for the development of vaccines

Estudio de seroprevalencia de HVS 1-2 en gestantes y recién nacidos de 2017 a 2021

El virus herpes simple (VHS) pertenece a la subfamilia alfa virus, miembro de la familia Herpes viridae. Existen dos tipos de VHS íntimamente relacionados, el VHS tipo 1 (VHS1) y el VHS tipo 2 (VHS2), que causan enfermedades de diversa gravedad. El VHS1 se transmite principalmente por contacto de boca a boca y el VHS2 se transmite por vía sexual; ambos pueden causar herpes genital. La carga de morbimortalidad a nivel mundial derivada de patógenos de transmisión sexual compromete la vida, así como la salud sexual y reproductiva, y la salud del recién nacido. Objetivos: Determinar la seroprevalencia IgG e IgM por VHS1 y VHS2 de los recién nacidos y madres en el periodo de enero 2017 a julio 2021 en un hospital de tercer nivel. Materiales y Métodos: Estudio observacional, retrospectivo de corte transversal de enero 2017 a julio 2021. Se midió anticuerpos IgG e IgM en recién nacidos y gestantes de ultimo trimestre, utilizando el método de ELISA. Resultados: De un total de 4712 serologías IgG e IgM de madres y RN analizados la seroprevalencia de IgG en gestantes fue cercana al 100% con valor similar en los RN (87%), la seroprevalencia de IgM en las madres fue 0,23% y de los RN 0,36% con tendencia ascendente. Conclusión: la seroprevalencia de IgG para VHS es elevada, en cambio la seroprevalencia de IgM en gestantes y recién nacidos en el periodo de estudio es significativamente baja.

The herpes simplex virus (HSV) belongs to the alpha virus subfamily, a member of the family Herpes viridae. There are two closely related types of HSV, HSV type 1 and HSV-2, which cause diseases of varying severity. HSV-1 is transmitted mainly by mouth-to-mouth contact and HSV-2 is transmitted sexually, both of which can cause genital herpes. The global burden of morbidity and mortality from sexually transmitted pathogens compromises life, as well as sexual and reproductive health, and the health of the newborn. Objective: To determine the IgG and IgM seroprevalence for HSV 1 - 2 of newborns and mothers in the period from January 2017 to July 2021 in a third level hospital. Materials and Methods: Observational, retrospective, cross-sectional study of January 2017 to July 2021. IgG and IgM antibodies were measured in newborns and pregnant women in the last trimester, using the ELISA method. Results: Of a total of 4712 IgG and IgM serologies of mothers and newborns analyzed the seroprevalence of IgG in pregnant women was close to 100% with similar value in newborns (87%), IgM seroprevalence in mothers was 0.23% and the RN 0.36% with an upward trend. Conclusion: The IgG seroprevalence for HSV is high, while the IgM seroprevalence in pregnant women and newborns during the study period is significantly low.

Encefalitis autoinmune posherpética. Caso clínico pediátrico / Autoimmune post-herpes simplex encephalitis. A pediatric clinical case report

La encefalitis por virus herpes simple (VHS) es una causa frecuente de encefalitis grave y potencialmente fatal. La encefalitis autoinmune posherpética (EAPH) afecta a un porcentaje de los pacientes que han presentado encefalitis herpética (EH) y se caracteriza por la aparición de nuevos síntomas neurológico/psiquiátricos, y/o por el empeoramiento de los déficits adquiridos durante la infección viral dentro de un lapso temporal predecible. Se produce por un mecanismo no relacionado con el VHS, sino por fenómenos autoinmunes, y es susceptible de tratamiento con inmunomoduladores. Se presenta el caso de un varón de 5 años de edad con EAPH que requirió tratamiento inmunomodulador, de primera y segunda línea, con buena evolución y remisión de los síntomas.

Herpes simplex virus (HSV) encephalitis is a common cause of severe and potentially fatal encephalitis. Autoimmune post-herpes simplex encephalitis (AIPHSE) affects a percentage of patients who developed herpes simplex encephalitis (HSE) and is characterized by the onset of new neurological/psychiatric symptoms and/or worsening of deficits acquired during the herpes infection within a predictable time frame. It is caused by a mechanism not related to HSV, but by autoimmune conditions, and is susceptible to treatment with immunomodulators. Here we describe the case of a 5-year-old boy with AIPHSE who required first- and second-line immunomodulatory treatment, with an adequate course and remission of symptoms.

Estudios de Seguridad Preclínica del extracto hidroalcohólico de semillas de Opuntia soehrensii, una especie alto-andina con actividad anti-Herpes Virus, en ratas Sprague Dawley / Preclinical safety of the hydroalcoholic extract of Opuntia soehrensii seeds with anti-herpes virus activity, in SD rats

Introducción. Alrededor de 3700 millones menores de 50 años con infección por VHS-1 y 491 millones de personas de 15 a 49 años cursan con infección por VHS-2 en el mundo; sus síntomas, vesículas o ulceras dolorosas reaparecen periódicamente. El tratamiento convencional disminuyó su efectividad en cepas resistentes e inmunodeprimidos. Alternativas terapéuticas con extractos de plantas medicinales y potencial antiviral, como Opuntia soehrensii Brito conocida como "ayrampù" en Bolivia, utiliza infusión de sus semillas como analgésico, antidiabético, hipotensor y febrífugo. En vapores por inhalación para afecciones respiratorias; como tintura tópica en lesiones dérmicas de viruela, sarampión y herpes labial. Objetivo. Evaluar la seguridad preclínica de un gel que contiene el extracto hidro-alcohólico de semillas de Opuntia soehrensii en diferentes dosis, aplicado en la mucosa vaginal de ratas Sprague Dawley. Material y métodos. Se ejecutaron protocolos de toxicidad aguda y subaguda para evaluar la respuesta sistémica, a través de marcadores bioquímicos y de comportamiento, y la respuesta local en mucosa vaginal, mediante estudios histopatológicos, en grupos de animales a los que se aplicó el gel con diferentes concentraciones del extracto de Opuntia soehrensii, comparados con un grupo control y otro que recibió solo el vehículo. Resultados. Se encontró que los indicadores sistémicos de comportamiento y ganancia de peso no mostraron diferencias entre grupos. Los indicadores hematológicos y bioquímicos mostraron resultados fisiológicamente esperados y sin cambios en los grupos de estudio. La citología expuso conservación del fenotipo celular para las fases del ciclo estral en todos los grupos. Los indicadores histológicos de reacción local e integridad celular se distribuyeron de igual manera en los todos los grupos. Conclusión. La aplicación de un gel de Opuntia soehrensii no muestra niveles apreciables de toxicidad local y sistémica, lo que permite recomendar la iniciación de estudios de aplicación clínica.

Introduction. Around 3.7 billion people under 50 years of age are infected with HSV-1 and 491 million people between the ages of 15 and 49 are infected with HSV-2 in the world; his symptoms, vesicles or painful ulcers recur periodically. Conventional treatment decreased its effectiveness in resistant and immunosuppressed strains. Therapeutic alternatives with extracts of medicinal plants and antiviral potential, such as Opuntia soehrensii Brito known as "ayrampù" in Bolivia, uses infusion of its seeds as an analgesic, antidiabetic, hypotensive and febrifuge. In vapors by inhalation for respiratory conditions; as a topical tincture in skin lesions of smallpox, measles and cold sores. Objectives . To evaluate the preclinical safety of a gel containing the hydroalcoholic extract of Opuntia soehrensii seeds in different doses, applied to the vaginal mucosa of Sprague Dawley rats. Material and Methods. Acute and sub-acute toxicity protocols were carried out to evaluate local response in the vaginal mucosa, through histo pathological studies, and systemic responses, through biochemical and behavioral markers, in groups of animals to which the gel with different concentrations of the extract of Opuntia soehrensii was applied, compared with a control group and another that received only the vehicle. Results. It was found that the histological indicators of local reaction and cell integrity were equally distributed in all groups. Cytology showed conservation of the cell phenotype for the phases of the estrous cycle in all groups. The systemic indicators of behavior and weight gain did not show differences between groups. Hematological and biochemical indicators showed results ranged in physiologic parameters, without changes in the study groups. Conclusion. The application of a gel from Opuntia soehrensii does not show appreciable levels of local and systemic toxicity, which makes it possible to recommend the initiation of clinical application studies.

Coronavirus disease 19 (COVID-19) and viral keratouveitis – unraveling the mystery

To demonstrate viral proteins/inflammatory cytokines in a patient with unilateral keratouveitis. Retrospective case report. A 70-year-old Asian-Indian male presented with acute onset of blurring of vision in the left eye (OS) of 2 days duration. He had was coronavirus disease 2019 (COVID-19)-positive 3 months earlier. He had undergone cataract surgery/retinal laser photocoagulation in both the eyes. The corrected distance visual acuity (CDVA) (Snellen) in the right eye (RE) (OD) and left eye (LE) (OS) was 20/20 and 20/80, respectively. OS showed decreased corneal sensation, Descemet’s folds, mild stromal edema, and fine and pigmented keratic precipitates with anterior chamber 1+ flare and 1+ cells. Fundus evaluation showed scattered laser marks in the OD and temporal sectoral laser marks in OS. He was diagnosed with viral keratouveitis in OS. Tear samples were collected on Schirmer’s strips and tear wash for mass spectrometry and cytokines, which had 368 and 451 viral proteins in the RE and LE, respectively, using nano liquid chromatography–mass spectrometry, which were more than controls. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and varicella zoster virus proteins were detected. Cytokine analysis using flow cytometer analysis showed higher inflammation in OS as compared to OD. The patient was treated with oral acyclovir and topical steroids and resulted in resolution of his keratouveitis. SARS-CoV-2 proteins were present in the tear sample 3 months after COVID-19. The presence of viral proteins does not indicate causality

Enfermedad de castleman multicéntrica y tuberculosis diseminada en paciente HIV positivo / Multicentric Castleman disease and tuberculosis in HIV positive patient

Resumen Presentamos el caso de un hombre de 40 años, HIV positivo con regular adherencia al tratamiento, que consultó por episodios febriles intermitentes de dos años de evolución, agregando en los últimos dos meses dolor abdominal difuso progresivo y adenomegalias ge neralizadas indoloras. En el laboratorio presentó panci topenia, coagulopatía, hipoalbuminemia y reactantes de fase aguda aumentados. La tomografía computarizada (TC) de tórax, abdomen y pelvis únicamente evidenció hepato-esplenomegalia y adenomegalias generalizadas. Se realizaron múltiples exámenes microbiológicos, in cluyendo cultivos para Mycobacterium sp. de distintas muestras, todos con resultados negativos, a excepción de la RT-PCR para VHH-8. Se tomó biopsia escisional de ganglio iliaco izquierdo con hallazgos compatibles con enfermedad de Castleman. A pesar de reiniciar terapia antirretroviral, la sintomatología progresó, iniciando tratamiento con corticoides y ganciclovir. Luego de una semana, desarrolló falla mulitorgánica y anasarca, que contraindicaron los fármacos iniciados. Se realizó nueva TC de tórax que mostró infiltrados con patrón en árbol en brote en lóbulo superior derecho asociado a derra me pleural bilateral, y a nivel abdominal, progresión de hepato-esplenomegalia y ascitis. Pasó a unidad de cui dados intensivos 48 horas después por falla hepática ful minante. El paciente falleció en pocas horas. Se recibió postmortem el cultivo del aspirado traqueal positivo para Mycobacterium tuberculosis y la punción-biopsia hepática con granulomas no necrotizantes. Nuestro objetivo es remarcar la importancia de pesquisar tuberculosis activa en nuestro país frente a la sospecha de enfermedad de Castleman antes de iniciar tratamiento, y resaltar que la TBC también puede presentarse como complicación infecciosa elevando la morbimortalidad.

Abstract We present the case of a 40-year-old man, HIV posi tive with regular adherence to treatment, who consulted for intermittent febrile episodes during a two-years period, progressive diffuse abdominal pain and painless generalized lymphadenopathy in the last two months. Laboratory analysis showed pancytopenia, altered co agulation tests, hypoalbuminemia, and increased acute phase reactants. Computed tomography (CT) of the chest, abdomen and pelvis revealed hepato-splenomegaly and generalized lymphadenopathy. Multiple microbiological tests were performed, including cultures for Mycobacte rium sp. from different samples, with negative results, except for the RT-PCR for HHV-8. An excisional biopsy of the left iliac lymph node was taken with findings compatible with Castleman's disease. Despite restarting antiretroviral therapy, the symptoms progressed, starting treatment with steroids and ganciclovir. After a week, he developed multiple organ failure and anasarca, which contraindicated the drugs previously started. A new CT of the chest showed infiltrates with a tree-in-bud pattern in the right upper lobe with bilateral pleural effusion, and at the abdominal level, progression of hepatospleno megaly and ascites. He was transferred to the intensive care unit 48 hours later due to fulminant hepatic fail ure. The patient died within a few hours. Postmortem recieved culture results of the tracheal aspirate were positive for tuberculosis (TB) and the histopathology of the liver biopsy showed non-necrotizing granulomas. Our objective is to highlight the importance of screening for active TB, in our country, when Castleman's disease is suspected, before starting treatment, and to stand out that TB can also present as an infectious complication, increasing morbidity and mortality.

Seroprevalence of antibodies against herpesvirus type 2 in a female prison population in Mato Grosso / Soroprevalência de anticorpos contra herpesvírus tipo 2 em população prisional feminina mato-grossense

Descrever a soroprevalência de anticorpos contra herpes vírus simples 2 em reeducandas de uma cadeia pública feminina de Mato Grosso no ano de 2016. Trata-se de um estudo transversal com abordagem quantitativa, realizado com 50 reeducandas reclusas de uma cadeia pública feminina de Mato Grosso. A coleta de dados foi realizada por meio de entrevista com 50 mulheres. Para determinar a soroprevalência da infecção por HSV-2, foram analisadas amostras de soro pelo método ELISA em busca de anticorpos do tipo IgG no Laboratório de Imunologia Viral do Instituto Oswaldo Cruz ­ RJ. A soroprevalência de HSV-2 encontrada na população avaliada foi de 80%, valor muito superior ao relatado na população geral brasileira e em outras estudos com populações prisionais em todo o mundo. O perfil das reeducandas predominou entre mulheres jovens, pardas, com baixa escolaridade, solteiras e com renda mensal baixa. O presente estudo encontrou alta soroprevalência de anticorpos contra HSV-2 nesta população. Esses dados fornecem importantes informações que podem auxiliar na implementação de ações efetivas que melhor previnam e controlem a herpes genital, bem como as demais ISTs em populações encarceradas.

Rehabilitación protésica en defecto ocular provocado por herpes zóster

El herpes zóster es el cuadro clínico constituido por las manifestaciones dermatológicas (erupción vesiculosa) y neurológica (dolor). Es la expresión de la recurrencia del virus varicela-zóster latente en los ganglios sensitivos, su aparición se favorece por el envejecimiento y la inmunosupresión con una prevalencia que se estima en un 20 %. Se describe los pasos clínicos para la confección de una prótesis ocular en el mejoramiento estético a un paciente con defecto ocular en ojo izquierdo provocado por herpes zoster. Se trata de un paciente masculino de piel blanca de 50 años de edad, que acudió a la consulta de prótesis del Policlínico Universitario Julio Antonio Mella de la provincia Camagüey remitido del Servicio de Oculoplastia del Hospital Universitario Manuel Ascunce Domenech con diagnóstico de defecto ocular izquierdo por evisceración como consecuencias de infección por herpes zoster y antecedente de inmunodepresión. El paciente expuso que la pérdida ocular fue por las complicaciones que se fueron sucediendo en la medida que se agravó su cuadro clínico. Además, refirió que presentaba dolor en la zona y que le irradiaba a la cabeza y que le preocupaba su estética. Se determinó la elaboración de una prótesis ocular acrílica para mejorar el aspecto estético, lo cual permitió que el paciente mejorara su autoestima y calidad de vida.

Herpes zoster is the clinical picture constituted by dermatological (vesicular rash) and neurological (pain) manifestations. It is the expression of the recurrence of the latent varicella-zoster virus in the sensitive ganglia, its appearance is favored by aging and immunosuppression with a prevalence estimated at 20%. We describe the clinical steps for the fabrication of an ocular prosthesis for the aesthetic improvement of a patient with ocular defect in the left eye caused by herpes zoster. This is a 50-year-old male patient with white skin, who came to the prosthesis consultation of the Julio Antonio Mella University Polyclinic in Camagüey province, referred from the Oculoplasty Service of the Manuel Ascunce Domenech University Hospital with a diagnosis of left ocular defect due to evisceration as a consequence of herpes zoster infection and a history of immunosuppression. The patient explained that the ocular loss was due to the complications that occurred as his clinical condition worsened. In addition, he reported that he had pain in the area that radiated to the head and that he was concerned about his esthetics. It was decided to make an acrylic ocular prosthesis to improve the esthetic aspect, which allowed the patient to improve his self-esteem and quality of life.

Pole-to-pole involvement of varicella zoster virus reactivation following COVID-19 vaccination

The aim of this study is to report the clinical features, imaging findings including confocal imaging, corneal nerve fiber analysis, and management outcomes in a series of three cases of varicella zoster virus (VZV) reactivation following one dose of coronavirus disease 2019 (COVID-19) vaccination. This was a retrospective and observational study. All the patients who developed uveitis post-vaccination were pooled together. Patients who had VZV reactivation were included. Two cases had polymerase chain reaction positive for VZV from aqueous humor. At the time of presentation, IgG and IgM spike protein antibodies for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) were tested. Out of this pool, three patients with classical features to describe pole-to-pole manifestations were chosen. A 36-year-old lady with post-vaccination sclerokeratouveitis associated with reactivation of herpes zoster ophthalmicus, a 56-year-old lady with post-vaccination acute anterior uveitis associated with herpes zoster ophthalmicus, and a 43-year-old gentleman with post-vaccination acute retinal necrosis were included. We present a possible link between anti-SARS-CoV-2 virus vaccination and varicella zoster reactivation in these patients and also describe the clinical features, imaging findings including confocal imaging, corneal nerve fiber analysis, and management with detailed discussion.

Choroidal lesions in varicella zoster virus uveitis

Purpose: To evaluate choroidal lesions with spectral domain optical coherence tomography (SD?OCT) scan in varicella zoster virus (VZV) uveitis. Methods: VZV?uveitis cases which underwent OCT scan for choroidal lesions were studied. SD?OCT scan passing through these lesions was studied in detail. Subfoveal choroidal thickness (SFCT) during active and resolved stages was studied. Angiogaphic features were studied where available. Results: Thirteen out of 15 cases had same?sided herpes zoster ophthalmicus skin rashes. All except three patients had old or active kerato?uveitis. All eyes demonstrated clear vitreous and a single or multiple hypopigmented orangish?yellow choroidal lesions. The number of lesions remained unchanged during the follow?up on clinical examination. SD?OCT over lesions (n = 11) showed choroidal thinning (n = 5), hyporeflective choroidal elevation during active inflammation (n = 3), transmission effects (n = 4), and ellipsoid zone disruption (n = 7). The mean change in SFCT (n = 9) after resolution of the inflammation was 26.3 ?m (range: 3–90 ?m). Fundus fluorescein angiography showed iso?fluorescence over lesions in all (n = 5), but indocyanine green angiography (n = 3) showed hypofluorescence at lesions. Mean follow?up was 1.38 years (range: 3 months–7 years). De?novo appearance of choroidal lesion during the first relapse of VZV?uveitis was captured in one case. Conclusion: VZV?uveitis can cause focal or multifocal hypopigmented choroidal lesions with thickening or scarring of choroidal tissue, depending on the disease activity.

Serum interleukin-6 levels are increased in post-herpetic neuralgia: a single-center retrospective study

Abstract Background: Studies have shown that the overall incidence rate of herpeszoster (HZ) in China is 6.64 cases per 1000 people, despite such harms brought by postherpetic neuralgia (PHN), the mechanism of the disease remains unclear in China. Currently, effective biomarkers to predict PHN remain unavailable, which makes it difficult to prevent and successfully treat PHN. Objectives: The aim of the study was to determine the serum interleukin-6 level in PHN. Methods: The serum levels of interleukin 6 (IL-6) were measured by multi-antibody sandwich ELISA. The likert scale was used to represent the degree of neuralgia in the patients. Patients with PHN were divided into a mild PHN group and a severe PHN group according to the Likert scale. ROC curve was performed for evaluating the diagnostic efficiency of IL6 for PHN. The correlation between the IL6 level and the Likert scale before and after treatment with gabapentin and mecobalamin was analyzed. Results: IL6 levels in PHN patients resulted higher compared to volunteers. Patients in the severe PHN group had a higher serum IL6 level than in the mild PHN group. The Likert scale score was related to the serum IL6 levels and the frequency of IL6 levels above the cutoff value (4.95pg/mL) in PNH groups before and after treatment (p<0.05). Study limitations: Pain is subjective. Some mental states, such as anxiety and depression, greatly influence an individual's perception of pain, and pain tolerance can vary between people. Therefore, pain scores can be affected by different individual factors. Conclusions: The serum IL6 levels may be used as a biochemical indicator of the severity of PNH.

Zoster sine herpete después de infección leve por SARS-CoV-2 / Zoster sine herpete after mild SARS-CoV-2 infection

El SARS-CoV-2 es un virus de afectación sistémica que impacta con gran intensidad en el sistema inmunológico; esto permite que virus de naturaleza latente, como el virus de Varicela Zoster (VVZ), tengan oportunidad de reactivarse y agravar el cuadro respiratorio con afectaciones cutáneas, mucosas y neurológicas. Se presenta un caso de Zoster sine herpete, durante la convalecencia del SARS-CoV-2, en un paciente masculino de 43 años, que acudió a consulta por dolor precordial de gran intensidad, sensación de escozor en tórax posterior y dificultad respiratoria; 10 días después de prueba de hisopado nasofaríngeo positiva para antígeno de SARS-CoV-2. Es importante no olvidar la probabilidad de presentaciones atípicas de virus latentes con el fin de realizar un diagnóstico y tratamiento oportuno a los pacientes.

SARS-CoV-2 is a systemic virus that has a strong impact on the immune system; this allows latent viruses, such as varicella-zoster virus (VZV), to reactivate and aggravate the respiratory symptoms with cutaneous, mucosal and neurological involvement. We present a case of Zoster sine herpete, during convalescence from SARS-CoV-2, in a 43-year-old male patient who presented with severe precordial pain, stinging sensation in the posterior thorax and respiratory distress; 10 days after a positive nasopharyngeal swab test for SARS-CoV-2 antigen. It is important not to forget the probability of atypical presentations of latent viruses to make a timely diagnosis and treatment of patients.

The Chinese herbal prescription JieZe-1 inhibits caspase-1-dependent pyroptosis induced by herpes simplex virus-2 infection in vitro / 中西医结合学报

OBJECTIVE@#JieZe-1 (JZ-1), a Chinese herbal prescription, has an obvious effect on genital herpes, which is mainly caused by herpes simplex virus type 2 (HSV-2). Our study aimed to address whether HSV-2 induces pyroptosis of VK2/E6E7 cells and to investigate the anti-HSV-2 activity of JZ-1 and the effect of JZ-1 on caspase-1-dependent pyroptosis.@*METHODS@#HSV-2-infected VK2/E6E7 cells and culture supernate were harvested at different time points after the infection. Cells were co-treated with HSV-2 and penciclovir (0.078125 mg/mL) or caspase-1 inhibitor VX-765 (24 h pretreatment with 100 μmol/L) or JZ-1 (0.078125-50 mg/mL). Cell counting kit-8 assay and viral load analysis were used to evaluate the antiviral activity of JZ-1. Inflammasome activation and pyroptosis of VK2/E6E7 cells were analyzed using microscopy, Hoechst 33342/propidium iodide staining, lactate dehydrogenase release assay, gene and protein expression, co-immunoprecipitation, immunofluorescence, and enzyme-linked immunosorbent assay.@*RESULTS@#HSV-2 induced pyroptosis of VK2/E6E7 cells, with the most significant increase observed 24 h after the infection. JZ-1 effectively inhibited HSV-2 (the 50% inhibitory concentration = 1.709 mg/mL), with the 6.25 mg/mL dose showing the highest efficacy (95.76%). JZ-1 (6.25 mg/mL) suppressed pyroptosis of VK2/E6E7 cells. It downregulated the inflammasome activation and pyroptosis via inhibiting the expression of nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing protein 3 (P < 0.001) and interferon-γ-inducible protein 16 (P < 0.001), and their interactions with apoptosis-associated speck-like protein containing a caspase recruitment domain, and reducing cleaved caspase-1 p20 (P < 0.01), gasdermin D-N (P < 0.01), interleukin (IL)-1β (P < 0.001), and IL-18 levels (P < 0.001).@*CONCLUSION@#JZ-1 exerts an excellent anti-HSV-2 effect in VK2/E6E7 cells, and it inhibits caspase-1-dependent pyroptosis induced by HSV-2 infection. These data enrich our understanding of the pathologic basis of HSV-2 infection and provide experimental evidence for the anti-HSV-2 activity of JZ-1.

Reasonable selection of antiviral agents for herpes zoster / 中华皮肤科杂志

Antiviral treatment is the core part in the treatment of herpes zoster. Based on the latest studies, consensus and guidelines, this article aims to provide a basis and reference for clinicians to make a reasonable choice of types and doses of antiviral agents. Valacyclovir, a precursor of acyclovir with high oral bioavailability and great convenience of administration, is generally the first choice of oral antiviral agents; for some special cases, such as immunocompromised patients, intravenous drips of acyclovir should be selected when appropriate. Brivudine is often a better choice for patients with severe renal insufficiency; famciclovir or other antiviral agents should be considered for patients resistant to acyclovir; for immunocompromised patients resistant to acyclovir, intravenous drips of foscarnet sodium can be an option. Oral antiviral agents should be administered at adequate doses. Selecting appropriate antiviral agents and their doses can effectively relieve acute symptoms of patients and reduce the probability of postherpetic neuralgia.
