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.

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.

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.

Multi-disciplinary team of human herpes virus-6B encephalitis after liver transplantation / 器官移植

Objective To evaluate the role of multi-disciplinary team (MDT) in improving the diagnosis and treatment of human herpes virus-6B (HHV-6B) encephalitis after liver transplantation. Methods MDT consultation was delivered for one rare case of HHV-6B encephalitis after liver transplantation to establish an effective individualized treatment regime. Results On the 16 d after liver transplantation, the patient developed headache, and suddenly presented with unresponsiveness, unconsciousness, coma complicated with involuntary limb twitching on the 18 d. Blood ammonia level was increased. Brain CT scan showed cerebral ischemic changes. Electroencephalography prompted the epileptic seizure. After MDT consultation, the possibility of nervous system infection after liver transplantation was considered, and medication therapy was given to control the epileptic seizure. Cerebrospinal fluid examination via lumbar puncture hinted increased intracranial pressure. Real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) of the cerebrospinal fluid demonstrated that the patient was tested positive for HHV-6B nucleic acid, which confirmed the diagnosis of HHV-6B encephalitis. The immunosuppressant regime was adjusted, intravenous ganciclovir was given for antiviral treatment, and active interventions were delivered to prevent and treat relevant complications. Epileptic seizure disappeared after 4 d, and neurological symptoms were significantly alleviated after 2 weeks. After 4-week antiviral treatment, the patient was tested negative for virology testing, and the neurological function was restored to normal. Conclusions HHV-6B encephalitis rarely occurs after adult liver transplantation, which is primarily associated with the virus reactivation after use of immunosuppressant. MDT pattern may be employed to deepen the understanding of the patient's condition, formulate more effective individualized treatment regime, and enhance the clinical efficacy and safety.

Proctitis infecciosa transmitida sexualmente: reto diagnóstico y recomendaciones de tratamiento / Sexually transmitted infectious proctitis: diagnostic challenge and treatment recommendations

RESUMEN La proctitis infecciosa (PI) transmitida sexualmente es un proceso inflamatorio del recto secundario a la infección por gérmenes de transmisión sexual. Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum y el virus herpes simple (VHS) son las causas más comunes. Es más prevalente en hombres que tienen sexo con hombres (HSH) y en pacientes con infección por el virus de inmunodeficiencia humana (VIH), sin embargo, también se diagnostica en heterosexuales por cambios en el comportamiento sexual. La urgencia fecal, el exudado purulento o sanguinolento, la proctalgia y el tenesmo son las manifestaciones clínicas más frecuentes. La historia clínica detallada y un alto índice de sospecha son importantes para establecer el diagnóstico de esta patología; apoyados en los estudios endoscópicos, histológicos, serológicos y microbiológicos. Se recomienda el tratamiento empírico, con antibióticos o antivirales, según la sospecha clínica y siempre deben descartarse otras infecciones de transmisión sexual (ITSs).

ABSTRACT Sexually transmitted infectious proctitis is an inflammatory process of the rectum secondary to infection by sexually transmitted germs. Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum, and herpes simplex virus (HSV) are the most frequently pathogens. Infectious proctitis is more prevalent in men who have sex with men (MSM) and in patients with human immunodeficiency virus (HIV) infection, however, it is also diagnosed in heterosexuals by changes in sexual behavior. Fecal urgency, purulent or bloody exudate, proctalgia, and tenesmus are the most common clinical manifestations. Detailed clinical history and a high index of suspicion are important to establish the diagnosis of this pathology; supported by endoscopic, histological, serological, and microbiological studies. Empirical treatment with antibiotics or antivirals is recommended, depending on clinical suspicion, and other sexually transmitted infections (STIs) should always be ruled out.

Diagnosis of elephantiasis nostras verrucosa as a clinical mani-festation of Kaposi's sarcoma / Diagnóstico de elefantiasis nostras verrucosa como mani-festación clínica del Sarcoma de Kaposi

Elephantiasis nostras verrucosa, a rare manifestation of Kaposi's sarcoma, is a progressive cutaneous hypertrophy caused by chronic non-filarial lymphedema secondary to obstruction of the lymphatic system that can lead to severe disfigurement of parts of the body that have gravity-dependent blood flow, due to edema, fibrosis, and hyperkeratosis, especially lower extremities. Among the various conditions that can induce chronic lymphedema are tumors, trauma, radiotherapy, obesity, hypothyroidism, chronic venous stasis, and AIDS-related Kaposi's sarcoma. Kaposi's sarcoma is a vascular tumor associated with the presence of human gammaherpesvirus 8 that is predominantly cutaneous, locally aggressive, with metastasis, and is associated with the production of factors that favor inflammation, lymphatic obstruction, and lymphedema.

Sarcoma de Kaposi epidémico en África Subsahariana / Epidemic Kaposi sarcoma in Sub-Saharan Africa

El sarcoma de Kaposi se ha convertido en uno de los tumores más prevalentes en África tras la epidemia de VIH, que afecta de una manera similar a hombres y mujeres. El retraso diagnóstico y el limitado acceso a tratamiento antirretroviral o quimioterapia condicionan el pronóstico de los pacientes que lo padecen. En este artículo se realiza una revisión sobre la referida enfermedad, con el objetivo de describir sus aspectos más relevantes en los últimos años en África, como son su epidemiología, caractéristicas clínicas y opciones terapéuticas existentes. Este tumor es provocado por la infección por virus herpes humano tipo 8, que resulta más prevalente en las zonas rurales del continente africano. Se postula la transmisión a través de la saliva como la vía más importante de contagio en África. La inmunodepresión que causa el VIH favorece el efecto oncogénico del virus. La forma epidémica de SK se manifiesta inicialmente como lesiones hiperpigmentadas o violáceas en la piel, que pueden extenderse a linfáticos o mucosas y a nivel sistémico, principalmente a pulmón o aparato digestivo. El síndrome de reconstitución inmune sistémica puede complicar la evolución del paciente. El inicio temprano de la terapia antirretroviral resulta imprescindible. Además, el pronóstico de los pacientes mejora con la suma de tratamiento quimioterápico con doxorrubicina, vincristina, etopóxido o bleomicina principalmente(AU)

Kaposi sarcoma (KS) has become one of the most prevalent tumors in Africa after the HIV epidemic. KS affects both men and women. Diagnostic delay and limited access to antiretroviral treatment or chemotherapy have an impact on the prognosis of KS patients. A review was conducted about KS with the purpose of describing its most outstanding characteristics in recent years in Africa, such as its epidemiology, clinical features, and existing therapeutic options. This tumor is caused by infection with human herpesvirus 8, which is more prevalent in rural areas of the African continent. Transmission via saliva was found to be the most important transmission route in Africa. HIV-related immunosuppression fosters the oncogenic effect of the virus. The epidemic form of KS initially presents as hyperpigmented or violet-colored skin lesions which may extend to lymph nodes or mucosae, or systemically, mainly to the lungs or the digestive tract. Systemic immune reconstitution syndrome may complicate the patient's evolution. Early start of antiretroviral therapy is indispensable. Additionally, prognosis improves with chemotherapy with doxorubicin, vincristine, etoposide or bleomycin, mainly(AU)

Objetivo: analisar a perspectiva dos acadêmicos de odontologia acerca do uso da laserterapia no tratamento do herpes tipo 1. Material e Métodos: estudo metodológico exploratório descritivo de abordagem quantitativa realizado no período de maio a junho de 2018, com 146 discentes de Odontologia de uma instituição de ensino privado superior, no município de Teresina - PI, por meio de questionário estruturado. Foram excluídos os discentes que não cursaram as disciplinas de Semiologia, Periodontia e Patologia Oral e que reprovaram nas respectivas disciplinas. Foram incluídos aqueles que apresentaram aprovação nas disciplinas de pré-requisito e que estão em atendimento clínico. Os dados foram analisados utilizando técnicas estatísticas descritivas, inferenciais e análises comparativas digitadas e analisados no SPSS na versão 13,0, com margem de erro de 5%. Este estudo encontra-se aprovado no Comite de Ética e Pesquisa sobre o parecer nº 2.861,891. Resultados: Em relação ao conhecimento da coloração da lesão, 48,63%, evidenciaram a cor avermelhada quando relacionada ao herpes e 40,41% desconhecem o tamanho da lesão. Em relação ao tempo de duração da lesão, o estudo revelou que 39,4% conheciam a frequência de duração da lesão e, quando associado à textura, 45,20% demonstraram não saber acerca da lesão tipo simples. No estudo, verificou-se que 75% desconhecem qual o tipo de laser deve ser escolhido para o tratamento, assim como 56,16% desconhecem o tempo de reutilização da terapia, 65,75 desconhecem a característica de recidiva após a utilização do uso do laser e 80,13 desconhecem o período de recidiva após a utilização do laser. Conclusão: concluiu-se que o conhecimento do herpes simples e da laserterapia tiveram relevância, pois os acadêmicos desconhecem a patologia herpes simples e a laserterapia como tratamento do mesmo. O laser foi considerado uma tecnologia eficaz, que permitirá tratamento rápido, efetivo e indolor e contribuirá para a diminuição das intervenções medicamentosas e para o custo-beneficio

Objective: to analyze the dentistry students' perspective about the use of laser therapy in the treatment of herpes type 1. Material and Methods: this is a descriptive exploratory methodological study with a quantitative approach conducted from May to June 2018, with 146 undergraduate students of dentistry from a private higher education institution in the city of Teresina ­ Piauí ­ Brazil, through a structured questionnaire. Students who did not go through the subjects of semiology, periodontics, and oral pathology and who failed in the mentioned subjects were excluded. Those who presented approval in these subjects and who are performing clinical care were included. Data were inserted and analyzed in SPSS version 13.0 with a margin of error of 5%, using descriptive, inferential and comparative analysis techniques. This study was approved by the Ethics and Research Committee under protocol number 2.861.891. Results: regarding the knowledge about the lesion color, 48.63% stated that red color was related to herpes. 40.41% did not know the size of the lesion. About the duration of the lesion, the study revealed that 39.4% knew the frequency of lesion duration and, when associated with the texture, 45.20% did not know about the Herpes simplex type lesion. The study verified that 75% did not know which type of laser should be chosen for treatment, as well as 56.16% did not know the proper time to reuse the therapy, and 65.75% did not know the recurrence characteristic after using laser, with 80.13% being unaware of the period of relapse after the use of laser therapy. Conclusion: it was concluded that the knowledge of herpes simplex and laser therapy represented relevance, since the students are not aware of herpes simplex pathology and the laser therapy in the management of herpes. Laser therapy was considered an effective technology, which will allow rapid, effective and painless treatment, and will contribute to the reduction of drug interventions and improve the benefit-cost ratio

Dual herpes virus reactivation complicated with encephalitis caused by direct-acting antiviral agents

@#Direct-acting antiviral agents (DAAs) have been the mainstream treatment of hepatitis C because of tolerability and efficacy. A 67-year-old man presented with acute drowsiness preceded by headache after starting DAAs (sofosbuvir and velpatasvir) for treatment of hepatitis C. Herpes zoster and herpes simplex stomatitis were noted. Later, HSV-1 encephalitis was diagnosed based on positive HSV1-PCR of CSF, while other tests were negative including HSV2-PCR, syphilis, culture of bacteria, tuberculosis and fungus. Further study showed the presence of concomitant Sjögren syndrome. The patient recovered well with the combination of intravenous acyclovir and steroid. Immune reconstitution inflammatory response (IRIS) may be the most important mechanism of this patient’s severe illness. In conclusion, severe CNS infection instead of just peripheral nervous system involvement may occur due to herpes virus reactivation caused by DAAs. Screening of autoimmune markers may be considered before DAA therapy

Comparison of detection rates of herpes virus and enterovirus in paired cerebrospinal fluid and serum specimens of patients with viral encephalitis / 中华实验和临床病毒学杂志

Objective@#To compare the detection rate of herpes virus and enterovirus (EV) in paired cerebrospinal fluid and serum samples of patients with viral encephalitis.@*Methods@#A total of 109 paired cerebrospinal fluid and serum specimens were collected from patients who were clinically diagnosed with suspected viral meningitis in Children′s Hospital of Hunan from December 2017 to February 2018. One-step nested real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-PCR) and real-time fluorescence quantitative PCR were used to detect enterovirus and herpes virus respectively and the detection rates of different virus and sample types were analyzed. SPSS 17.0 was used for statistical analysis of the test result .@*Results@#Among the 109 pairs of specimens, the positive rates of human herpes virus type 6 (HHV6), herpes simplex virus-1 (HSV1), Epstein-Barr virus (EBV), cytomegalovirus (CMV) and enterovirus group A type 71(EV-A71) in serum were 7.34%, 4.59%, 7.34%, 9.17% and 10.09%, respectively, and in cerebrospinal fluid were 5.50%, 2.75%, 0, 5.50%, and 6.42%, respectively. The result showed that there were statistically significant differences between the two types of specimens for herpes virus and enterovirus (P<0.05). In cerebrospinal fluid and serum samples, the longest time for EV-A71 positive detection was 2 and 7 days after onset, respectively; the longest time for CMV positive detection was 3 and 26 days after onset, respectively; the longest time for HHV6 positive detection was 7 and 8 days after onset, respectively; the longest time for HSV1 positive detection was both 12 days after the onset; in serum samples, the longest time for EBV positive detection was10 days after onset, but in cerebrospinal fluid, no EBV was detected within 10 days of onset.@*Conclusions@#EV-A71 is the most prevalent pathogen causing viral encephalitis in hunan, the overall positive rate of virus in serum samples was higher than that in cerebrospinal fluid samples. Virus stays longer in serum than in cerebrospinal fluid. It is suggested that the time is of great significance for the pathogen detection of children with viral encephalitis, the specimen type can be selected reasonably according to the time of onset.

Risk factors and clinical features of septic patients with human herpes viruses' nucleic acid detected positive in blood / 中华急诊医学杂志

Objective To measure the reads numbers of Human Herpes Virus in blood sample from patients with sepsis by using Next Generation sequencing (NGS) and explore the relationship between read number of virus and the severity, prognosis, immune status of septic patients.Methods Blood sample and clinical information from 150 patients with sepsis were enrolled in this study. All patients' blood samples were sent to perform NGS pathogenic test. According to the results of NGS, septic patients were divided into HHV-detected group and HHV-undetected group. Besides, patients were scored with Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ ) on the day of blood collection. The counts of total leukocytes, lymphocytes and the levels of cytokines were also measured. Results 51.3 percent of septic patients were detected with HHV nucleic acid. The APACHE Ⅱ and SOFA scores were significantly higher in HHV-detected patients compared with patients in HHV-undetected group. Besides, patients who had a higher SOFA score might lead to a higher detection rate of HHV. Moreover, the 28-day and 90-day mortality rates were higher in detected group (P< 0.01). The detection of HHV nucleic acid was positively correlated with a high 90-day mortality rate (P= 0.0056). One-way analysis of variance revealed that the counts of total lymphocyte and different types of lymphocyte (CD19+B、CD4+T、CD8+T、CD56+ lymphocyte) were significantly less in detected group than that in undetected group. Furthermore, both the levels of pro-inflammatory cytokines (TNF-α、IL-2R、IL-6、IL-8) and anti-inflammatory cytokines (IL-10) in detected group were significantly higher than those in undetected group. Gender, age, APACHE Ⅱ , SOFA, IL-2R, IL-10, CD19+B lymphocyte and T cells, were still significant even after multivariate logistic analyses. Conclusions The detection rate of HHV nucleic acid in patients with sepsis was high. The detection of HHV was a high-risk factor of death in patients with sepsis. The cut-off value which is more than 100 had a significant clinical value. The infection of HHV could be conducted by dysfunction of immunity.

Eyelid Kaposi Sarcoma in an HIV-negative Patient

Kaposi sarcoma (KS) is a low-grade, multicentric vascular neoplasm. Most commonly, it involves the skin, but it can occur at any site on the body. The cutaneous lesions are often located on the lower legs, genitalia, oral mucosa, and face. KS is categorized in four different types: classic, endemic, epidemic or AIDS associated, and transplantation associated. We report a case of HIV-negative, classic KS located on the eyelid. The eyelid lesion was completely excised, and after a 1-year follow-up, no recurrences were observed. Ocular involvement by KS in a patient who is serologically negative for HIV is extremely rare.
