Study of T lymphocyte subsets in infectious mononucleosis syndrome / 中国医师杂志

Objective T lymphocyte subsets in children with characteristics observed with infec-tious mononucleosis (infectious mononucleosis,IM),to explore its reference value.Methods January 2011 to December 2014 during a pediatric door altogether 115 cases of hospitalized children were divided in-to three groups,51 cases of IMgroup,33 atypical group,31 patients flyers syndrome,selecting outpatient healthy children as 101 cases the control group.For each group T lymphocyte subsets:CD3 + CD4 +,CD3 +CD8 +,CD4 +/CD8 + ratio,analyze the differences between the groups was significant.Results Compared four groups of T lymphocyte subsets (CD3 +,CD3 +CD4 +,CD3 +CD8 +,CD4 +/CD8 + ratio)change char-acteristics,IMgroup,atypical group,flyers syndrome group and the control group,the difference was sta-tistically significance (P 0.05),two groups of children described in T there was no significant difference in lymphocyte immune.Conclusions T lymphocyte subsets have some reference value in the differential diagnosis of IM,and prompt clinical attention to EB virus infection in chil-dren whose immune function,can help prevent and treat.

O vírus Epstein-Barr e a mononucleose infecciosa / Epstein-Barr virus and infectious mononucleosis

JUSTIFICATIVA E OBJETIVOS: A mononucleose infecciosa (MI) é uma doença viral, contagiosa, causada pelo vírus Epstein-Barr (EBV). Apresenta distribuição universal e pode ocorrer em qualquer faixa etária. O presente estudo teve como objetivo descrever a interação entre o EBV e o Homo sapiens sapiens, no que diz respeito especialmente à MI. Para isso, realizou busca no Pubmed e no Scielo, bem como em livros-textos. Os artigos selecionados foram lidos e as informações organizadas de forma a contemplar os aspectos patogênicos - enfatizando o papel do EBV na doença -, epidemiológicos e diagnósticos dessa entidade. CONTEÚDO: A infecção do epitélio da orofaringe permite a replicação do vírus, o qual passa a ser eliminado na saliva, o que explica a transmissão pelo contato com tal fluido biológico. O período de incubação é de quatro a seis semanas. Manifesta-se do ponto de vista clínico, usualmente, com febre, faringite e linfadenomegalia generalizada de caráter agudo ou subagudo. As alterações laboratoriais incluem leucocitose, reações leucemoides, trombocitopenia e anemia hemolítica autoimune, além de aminotransferases elevadas e bilirrubina aumentada, destacando-se que a linfocitose atípica é habitualmente observada. O diagnóstico diferencial da MI abrange as demais causas de síndrome de mononucleose. O tratamento é sintomático, não havendo fármaco antiviral específico. Analgésicos habituais podem ser usados para a terapêutica da dor. CONCLUSÃO: Díspares grupos têm trabalhando no desenvolvimento de vacinas para o EBV, porém, a possibilidade de tumorigênese pelo vírus tem trazido inúmeras dificuldades para a confecção de imunoprofilaxia efetiva.

BACKGROUND AND OBJECTIVES: Infectious mononucleosis (IM) is a widespread viral disease caused by Epstein-Barr virus (EBV). It occurs worldwide and can reach any age group. This article aims at describing the interaction between EBV and Homo sapiens sapiens, regarding especially IM. Thus, a research on PubMed and Scielo was performed, as well as on books. The selected articles were read and the information was organized inorder to contain the pathological - emphasizing the role of EBV on the disease -, epidemiological aspects and its diagnosis. CONTENTS: The infection of the epithelium of the oropharynx leads to the replication of the virus, which is eliminated via saliva, and accounts for the transmission through contact with this biological fluid. The incubation period lasts from four to six weeks. Clinically, the classic symptoms are usually fever, faryngitis and generalized lymphadenopathy, which can be acute or subacute. The laboratorial changes include leukocytosis, leukemoid reactions, thrombocytopenia and severe autoimmune hemolytic anemia, besides high levels of transaminases and bilirubin; atypical lymphocytosis is usually observed. The differential diagnosis of IM includes the other causes of mononucleosis syndrome. Treatment is symptomatic and there is not a specific antiviral medicine. Common analgesics can be used to treat pain. CONCLUSION: Diverse groups have worked on the development of a vaccine for EBV; however, the possibility of tumorigenesis by the virus has brought up several difficulties to the production of an effective immunoprophylaxis.

Clinical Characteristics of Extrapulmonary Complication Induced by Mycoplasma Pneumoniae Infection Complicating with Infectious Mononucleosis Syndrome / 实用儿科临床杂志

Objective To approach the clinical characteristics of extrapulmonary complication induced by mycoplasma pneumoniae(MP) infection and infectious mononucleosis syndrome. Methods The MP-IgM(+), EBV- IgM(+) were determined by enzyme- linked immunosorbent assay.There were 18 cases infected with MP and infectous mononucleosis syndrome with abnormal fever,cervix lyphadenectasis,pharyngitis,liver and spleen intumescence,lung infection, and so on.They were analyzed by reviewing.Results There were 8 cases(44.4%) with extrapulmonary complication, among them 3 cases(16.6%) with liver injury,1 case (5.56%) with heart injury,2 cases(11.1%) with both heart and liver injuries,1 case(5.56%) with urinary system injury (nephritis), 1 case (5.56%) with nervous system injury (encephalitis).The complication usually arised 1 week after primary affection, but had no typical clinical symptoms.There was only 1 case with encephalitis who expressed the symptom of nervous system symptom firstly, and was clinically dia- gnosed by assistant examinations. All the cases recovered after 3 weeks′ treatment with macrolides, 5-7 days with ganciclovir, and also with regular complication and support treatments.Conclusions The incidence of extrapulmonary complication induced by MP infection and infectous mononucleosis syndrome is higher than that by the single infection, and its clinical symptom isn′t obvious and is easy to be covered by original illness. And a few showing the extrapulmonary as the first symptom is easily mistakenly diagnosed .As a result, the prognosis is favorable if we make subsidiary inspection and diagnosis as soon as possible and give it with regular treatment.
