A school-aged boy with nephrotic syndrome with cough for one month and shortness of breath for half a month / 中国当代儿科杂志

A boy, aged 6 years and 11 months, was admitted due to nephrotic syndrome for 2 years, cough for 1 month, and shortness of breath for 15 days. The boy had a history of treatment with hormone and immunosuppressant. Chest CT after the onset of cough and shortness of breath showed diffuse ground-glass opacities in both lungs. Serum (1, 3)-beta-D glucan was tested positive, and the nucleic acid of cytomegalovirus was detected in respiratory secretions. After the anti-fungal and anti-viral treatment, the child improved temporarily but worsened again within a short period of time.

Manifestaciones clínicas asociadas al síndrome de TORCH / Clinical manifestations associated to the TORCH syndrome

Las infecciones neonatales se adquieren comúnmente por la vía intrauterina o durante el parto. El acrónimo TORCH fue designado para un grupo de infecciones comunes, y se utiliza de forma universal para caracterizar el cuadro clínico que presenta el feto o el recién nacido compatible con una infección congénita que incluye rash, hepatoesplenomegalia, hidrocefalia o microcefalia, alteraciones cardiovasculares, auditivas y oculares. Las siglas TORCH comprenden toxoplasmosis, otros (sífilis y HIV), rubeola, citomagalovirus y herpes simple. Lo más importante de este término es que dota al médico de las herramientas para hacer un enfrentamiento racional, tanto diagnóstico como terapéutico, y establecer un plan de acción para minimizar los daños producidos por estas infecciones. Con esta revisión nos proponemos destacar las manifestaciones clínicas más importantes asociadas al síndrome de TORCH, así como sus vías de transmisión, diagnóstico y tratamiento de las infecciones que lo comprenden, teniendo en cuenta que con relativa frecuencia en nuestra institución son interconsultados estos pacientes y que de su evaluación correcta y oportuna puede depender un diagnóstico certero, con un tratamiento adecuado, y una mejor evolución de estos(AU)

Neonatal infections are often acquired during pregnancy or childbirth. The acronym TORCH refers to a group of common infections, and is universally used to characterize a clinical status of fetuses or newborns which is compatible with a congenital infection, including rash, hepatosplenomegaly, hydrocephalus or microcephaly, as well as cardiovascular, hearing or sight disorders. The initials TORCH stand for Toxoplasmosis, Other infections (such as syphilis or HIV), Rubella, Cytomegalovirus and Herpes simplex. The term is especially useful because it provides doctors with the tools required for a rational diagnostic and therapeutic response and the development of an action plan aimed at minimizing the damage caused by these infections. The purpose of this review is to present the most important clinical manifestations of the TORCH syndrome, as well as its routes of transmission, diagnosis and treatment of the infections making it up(AU)

Síndrome de TORCH: enfoque racional del diagnóstico y tratamiento pre y post natal. Recomendaciones del Comité Consultivo de Infecciones Neonatales Sociedad Chilena de Infectología, 2016 / TORCH syndrome: Rational approach of pre and post natal diagnosis and treatment. Recommendations of the Advisory Committee on Neonatal Infections Sociedad Chilena de Infectología, 2016

There is a lot of bacterial, viral or parasite infections who are able to be transmitted vertically from the mother to the fetus or newborn which implicates an enormous risk for it. The TORCH acronym is used universally to refer to a fetus or newborn which presents clinical features compatible with a vertically acquired infection and allows a rational diagnostic and therapeutic approach. The traditional "TORCH test" is nowadays considered not appropriate and it has been replaced for specific test for specific pathogens under well defined circumstances. The present document reviews the general characteristics, epidemiology, pathogenesis, diagnostic and therapeutic options for the most frequently involved pathogens in the fetus or newborn with TORCH suspicion.

Existen numerosas infecciones bacterianas, virales y parasitarias que pueden transmitirse desde la madre al feto o recién nacido (RN) y que significan un riesgo para él. El acrónimo TORCH se utiliza en forma universal para caracterizar a aquel feto o RN que presenta un cuadro clínico compatible con una infección congénita y que permite un enfrentamiento racional, tanto diagnóstico como terapéutico. El concepto tradicional de realizar un "test de TORCH" sin consideraciones específicas a cada paciente, hoy en día se considera no adecuado y ha sido reemplazado por exámenes específicos para patógenos específicos bajo circunstancias bien definidas. El presente documento revisa las características generales, epidemiológicas, patogénicas, diagnósticas y terapéuticas de los patógenos más frecuentemente involucrados en el estudio de pacientes con sospecha de TORCH.

Cytomegalovirus infection in transplant recipients

Cytomegalovirus infection is a frequent complication after transplantation. This infection occurs due to transmission from the transplanted organ, due to reactivation of latent infection, or after a primary infection in seronegative patients and can be defined as follows: latent infection, active infection, viral syndrome or invasive disease. This condition occurs mainly between 30 and 90 days after transplantation. In hematopoietic stem cell transplantation in particular, infection usually occurs within the first 30 days after transplantation and in the presence of graft-versus-host disease. The major risk factors are when the recipient is cytomegalovirus seronegative and the donor is seropositive as well as when lymphocyte-depleting antibodies are used. There are two methods for the diagnosis of cytomegalovirus infection: the pp65 antigenemia assay and polymerase chain reaction. Serology has no value for the diagnosis of active disease, whereas histology of the affected tissue and bronchoalveolar lavage analysis are useful in the diagnosis of invasive disease. Cytomegalovirus disease can be prevented by prophylaxis (the administration of antiviral drugs to all or to a subgroup of patients who are at higher risk of viral replication) or by preemptive therapy (the early diagnosis of viral replication before development of the disease and prescription of antiviral treatment to prevent the appearance of clinical disease). The drug used is intravenous or oral ganciclovir; oral valganciclovir; or, less frequently, valacyclovir. Prophylaxis should continue for 90 to 180 days. Treatment is always indicated in cytomegalovirus disease, and the gold-standard drug is intravenous ganciclovir. Treatment should be given for 2 to 3 weeks and should be continued for an additional 7 days after the first negative result for viremia. .

Late cytomegalovirus infection after hematopoietic stem cell transplantation: case reports

Cytomegalovirus is related to high rates of morbidity and mortality after hematopoietic stem cell transplantation. This report highlights the importance of adequate monitoring and management of this infection. We report on two cases of patients with late subclinical cytomegalovirus infection. These patients were monitored for antigenemia by indirect immunofluorescence assay. Active cytomegalovirus infection is most common in the first three months after transplantation however the cases reported herein show the importance of monitoring for active infection after Day +100 post-transplantation. Early detection of active infection enables quick preemptive therapy. In conclusion, we emphasize that patients with risk factors for developing severe or late cytomegalovirus disease should be monitored for more than 100 post-transplant days as late active infection is a reality.

Infecção pelo citomegalovírus na gestação:uma visão atual / Cytomegalovirus infection in pregnancy: a current view

A infecção pelo citomegalovírus representa a mais prevalente infecção correlacionada com deficiência neurológica congênita. Apesar da ocorrência da transmissão vertical em taxas consideravelmente elevadas, nem sempre o feto é atingido. O risco de danos ao concepto é maior quando a infecção materna se desenvolve no primeiro trimestre ou no início do segundo trimestre. O recente desenvolvimento de testes sorológicos que visam a detecção de IgM e IgG específico, além do teste de avidez pelo IgG, representam os métodos mais confiáveis de diagnóstico da infecção materna, enquanto a amniocentese (PCR no líquido amniótico), em conjunto com exames de imagem possuem um papel significativo na detecção da infecção fetal. Apesar dos promissores estudos envolvendo novas técnicas de tratamento, a prevenção da doença continua sendo fundamental, por meio dos bons hábitos de higiene pessoal. O presente artigo busca revisar os aspectos mais atuais da infecção congênita pelo citomegalovírus, assim como técnicas de diagnóstico, tratamento e prevenção.

Cytomegalovirus infection represents the most prevalent infection correlated with congenital neurological deficit. Despite the high occurrence of vertical transmission rates, the fetus is not always committed. The risk of fetal damage is higher when maternal infection develops in the first trimester or early second trimester. The recent development of serological tests to detect specific IgM and IgG, as well as by IgG avidity testing, represents the most reliable methods for diagnosis of maternal infection, whereas amniocentesis (amniotic fluid PCR) associated with imaging methods have significant role in the detection of fetal infection. Despite the promising new techniques for studies involving treatment, prevention remains crucial through the good personal hygiene habits. The aim of this article is to review the most current aspects about the cytomegalovirus congenital infection, as well as techniques for diagnosis, treatment and prevention.

[Diagnostic and virological follow up of human cytomegalovirus infection]

The Human cytomegalovirus [HCMV] is a ubiquitous herpes virus and is a common virus worldwide. It is important in human pathology and causes serious diseases. Our study is to specify the biological, anatomical and epidemiological aspects, as well as the circumstance of the diagnostics and the principal treatments of infections with HCMV. The descriptive study covered all articles published in with the key words Cytomegalovirus, Immunocompromised patients, bone-marrow transplants, renal transplants, AIDS patients, PCR, pp65 antigenemia We found 200 articles published in international reviews. That has been eligible to the study. Most of these articles were concerned about experimental and clinical work [67%and 21%respectively]. The majority [80%] of the articles is written in English. The human cytomegalovirus is the origin of serious infections in patients having an immunity deficit. The study of the place of the HCMV in immunocompromised, is thus of an indisputable interest to understand the factors associated with this infection

Doença de inclusão citomegálica: contribuição ao estudo clínico e patológico / Cytomegalic inclusion disease: contribution to the clinical and pathological study

Foi feito um estudo retrospectivo de trinta casos de doença de inclusão citomegálica, dentre 83, diagnosticados microscopicamente pelo serviço de anatomia patológica do Hospital Universitário Antonio Pedro, no período de 1970 a 1989. O diagnóstico foi confirmado pela presença da célula de inclusão típica em vários órgãos. A seleção dos pacientes foi feita pela disponibilidade dos prontuários clínicos. Seis crianças eram recém-nascidas, 21 tinham menos de seis meses, e três mais de seis meses. Sete eram prematuros. Os achados clínicos mais freqüentes foram distúrbios respiratórios (60%), hepatomegalia (60%), diarréia protraída (53%), desnutrição (peso abaixo do percentil 2,5 - 46%), esplenomegalia (30%) e insuficência cardíaca congestiva (16,6%). Exantema petequial ocorreu em apenas dois recém-nascidos. Somente quatro crianças foram investigadas laborarorialmente para a doença. Concluiu-se que a forma clássica descrita em recém-nascidos não foi comum e que a doença de inclusão citomegálica deve ser considerada no diagnóstico diferencial daqueles lactentes que apresentem pneumonite associada à diarreia protraída ou a colestase.
