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.

Herpes Simplex Virus Esophagitis in an Immunocompetent Patient

We present the case of a 17-year-old patient with no known comorbidity or history who was admitted due to dysphagia. Endoscopy revealed ulcerated lesions in the distal esophagus that were positive for herpes simplex virus type 1 (HSV-1) on immunohistochemistry. An examination of HSV-1 esophagitis in the immunocompetent patient is made.

Se presenta el caso de un paciente de 17 años sin ninguna comorbilidad ni antecedente conocido que ingresó por disfagia. La endoscopia reveló lesiones ulceradas en el esófago distal que resultaron positivas para virus del herpes simple tipo 1 (VHS-1) en la inmunohistoquímica. Se hace una revisión de la esofagitis por VHS-1 en el paciente inmunocompetente.

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

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.

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.

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.

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.

Changes in CD100 expression and its regulatory effect on CD8 + T cell function in peripheral blood of patients with herpes zoster / 中华皮肤科杂志

Objective:To investigate changes in expression of plasma soluble CD100 (sCD100) and membrane-bound CD100 (mCD100) on peripheral T cells in patients with herpes zoster, and to observe the regulatory effect of exogenous CD100 on CD8 + T cells. Methods:A total of 53 patients with herpes zoster attending the Zhumadian Central Hospital from July 2019 to April 2021 were enrolled, so were 25 age- and sex-matched healthy controls. Anticoagulated venous blood samples were collected, plasma and peripheral blood mononuclear cells were isolated, plasma sCD100 levels were detected by enzyme-linked immunosorbent assay, and mCD100 expression on CD4 + and CD8 + T cells was determined by flow cytometry. After the purification of CD8 + T cells, the secretion levels of cytotoxic molecules and cytokines by CD8 + T cells were measured and compared between herpes zoster patients and controls. Some purified CD8 + T cells from herpes zoster patients were stimulated with recombinant human CD100 and recombinant varicella-zoster virus glycoprotein, and the effect of recombinant human CD100 on the secretion of cytotoxic molecules and cytokines by CD8 + T cells was investigated. Comparisons between groups were conducted by t test. Results:Plasma sCD100 levels were significantly lower in the herpes zoster group (1.12 ± 0.23 ng/ml) than in the control group (1.31 ± 0.28 ng/ml, t = 2.97, P = 0.004), the proportion of mCD100 + CD8 + T cells was significantly higher in the herpes zoster group (17.41% ± 4.26%) than in the control group (14.69% ± 3.70%, t = 2.52, P = 0.014), and no significant difference in the proportion of mCD100 + CD4 + T cells was found between the two groups (2.52% ± 0.58% vs. 2.32% ± 0.56%, t = 1.27, P = 0.208). The herpes zoster group showed significantly decreased mRNA expression of perforin and granzyme B in, and lower secretion levels of perforin, granzyme B, interferon-γ and tumor necrosis factor-α by CD8 + T cells compared with the control group (all P < 0.05). After stimulation with recombinant human CD100, levels of perforin, granzyme B, interferon-γ and tumor necrosis factor-α in the culture supernatant of CD8 + T cells (43.68 ± 14.12, 126.8 ± 22.92, 12.79 ± 3.66, 310.0 ± 79.90 pg/ml, respectively ) were significantly higher than those in non-stimulated group (34.55 ± 10.78, 99.04 ± 10.44, 9.53 ± 2.00, 275.6 ± 68.04 pg/ml, respectively, all P < 0.05) . Conclusion:There was an imbalance between sCD100 and mCD100 expression in patients with herpes zoster, and exogenous sCD100 may enhance the cytotoxicity of CD8 + T cells in herpes zoster patients.

Clinical efficacy of fire needling combined with cupping therapy on herpes zoster of acute stage and the effect on Th17/Treg cellular immune balance / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between the combined therapy of fire needling and cupping, and western medication on herpes zoster of acute stage, as well as the effects on Th17 and Treg cells and inflammatory factors, i.e. IL-10 and IL-17 in the peripheral blood.@*METHODS@#Eighty patients with herpes zoster of acute stage were randomly divided into a combined therapy (fire needling plus cupping) group and a western medication group, 40 cases in each one. In the combined therapy group, the pricking and scattering techniques with fire needle were used at ashi points and Jiaji (EX-B 2) corresponding to the affected spinal segments; afterwards, cupping therapy was delivered. The combined treatment was given once daily. In the western medication group, valaciclovir hydrochloride tablet and vitamin B1 tablet were administered orally. The duration of treatment in each group was 10 days. Before each treatment from day 1 to day 10 and on day 11 , the score of symptoms and physical signs was observed in the two groups separately. Before each treatment from day 1 to day 10 and on day 11, 30, 60, the score of visual analogue scale (VAS) and skin lesion indexes were observed in the two groups. On day 60, the incidence of postherpetic neuralgia was recorded in the two groups. The levels of Th17 and Treg cells, Th17/Treg ratio in the peripheral blood, as well as serum levels of IL-10 and IL-17 were detected before and after treatment in the two groups. The clinical efficacy was compared between the two groups.@*RESULTS@#From day 6 to day 10 during treatment and on day 11, the scores of symptoms and physical signs in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 3, day 6 to day 10 during treatment and day 11, day 30, VAS scores in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 60, the incidence of postherpetic neuralgia in the combined therapy group was lower compared with that in the western medication group (P<0.05). The blister arresting time and scabbing time in the combined therapy group were shorter than those of the western medication group (P<0.05). After treatment, the level of Th17, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 were all lower in comparison with those in the western medication group (P<0.05). The curative and remarkably effective rate was 82.5% (33/40) in the combined therapy group, higher than 62.5% (25/40) in the western medication group (P<0.05).@*CONCLUSION@#The early application of fire needling combined with cupping therapy can effectively treat herpes zoster of acute stage, relieve pain, and reduce the incidence of postherpetic neuralgia, which may be related to reducing the levels of Th17 and Treg cells, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 so that the cellular immune balance is modulated.

Preparation and application of high titer neutralizing antibody against varicella-herpes zoster virus / 中国生物制品学杂志

@#Objective To prepare high titer specific immune serum of varicella-herpes zoster virus(VZV)for the quality control of live attenuated varicella vaccine and live attenuated herpes zoster vaccine.MethodsMale rabbits were immunized with high purity recombinant gE glycoprotein combined with Freund's adjuvant,aluminum hydroxide adjuvant or MF59 adjuvant,2 rabbits in each group. On the 56th day after immunization,the maximum blood samples(heart or carotid artery)were collected from each rabbit to prepare serum,which was mixed with VZV for neutralization reaction,and then inoculated into a 6-well plate full of monolayer of MRC-5 human diploid cells. After incubation for 7 d,the number of plaques was counted and the neutralizing titer and virus neutralizing ability of immune serumwere determined. The serum with high neutralizing titer and virus neutralizing ability was selected for the identification test of live attenuated varicella vaccine and live attenuated herpes zoster vaccine VZV(Oka strain)working seed lot and the detection of exogenous virus factors.ResultsThe immune sera prepared by immunizing rabbits with various combinations of recombinant gE glycoprotein all showed neutralizing activity,among which the serum prepared by the combination of recombinant gE glycoprotein and Freund's adjuvant had the highest neutralizing titer of 1∶512 and the virus neutralizing ability of 240 000 PFU/mL;The prepared immune serum was usedfor the identification test of VZV(Oka strain)working seed lot and the detection of exogenous virus factors,of which all the results were in line with the requirements. Conclusion The recombinantgE glycoprotein could be used for the preparation of high titer neutralizing antibody against VZV,and the prepared high titer neutralizing antibody is suitable for thequality control of live attenuated varicella vaccine and live attenuated herpes zoster vaccine.

Secondary herpes zoster wound cured by allogeneic platelet-rich plasma: a case report / 中国输血杂志

【Objective】 To investigate the feasibility of allogeneic platelet-rich plasma (PRP) for the treatment of herpes zoster wounds secondary to systemic lupus erythematosus (SLE), especially large ulcer wounds. 【Methods】 The treatment process of a patient with massive herpes zoster wounds in perineum and hip accompanied by extensive soft tissue necrosis secondary to SLE was retrospectively analyzed. The clinical efficacy of allogeneic PRP was explored combined with treatment key points and literature review. 【Results】 The patient′s wound bed was prepared until the wound was fresh, then treated externally with allogeneic PRP 3 times a week. The wound was healed completely after 42 days. 【Conclusion】 In the case of autologous PRP unavailable or unsuitable, allogeneic PRP is a safe alternative, which can effectively promote tissue regeneration, and this patient achieved curative effect in a short period of time.
