ABSTRACT

O Informe Diário de Evidências é uma produção do Ministério da Saúde que tem como objetivo acompanhar diariamente as publicações científicas sobre tratamento farmacológico e vacinas para a COVID-19. Dessa forma, são realizadas buscas estruturadas em bases de dados biomédicas, referentes ao dia anterior desse informe. Não são incluídos estudos pré-clínicos (in vitro, in vivo, in silico). A frequência dos estudos é demonstrada de acordo com a sua classificação metodológica (revisões sistemáticas, ensaios clínicos randomizados, coortes, entre outros). Para cada estudo é apresentado um resumo com avaliação da qualidade metodológica. Essa avaliação tem por finalidade identificar o grau de certeza/confiança ou o risco de viés de cada estudo. Para tal, são utilizadas ferramentas já validadas e consagradas na literatura científica, na área de saúde baseada em evidências. Cabe ressaltar que o documento tem caráter informativo e não representa uma recomendação oficial do Ministério da Saúde sobre a temática. Foram encontrados 13 artigos e 8 protocolos.

ABSTRACT

A doença de Crohn se caracteriza como uma doença inflamatória, que acomete qualquer porção do trato gastrintestinal, resultante da desrregulação imunológica, gerenciada por fatores endógenos e exógenos. As formas de abordagem terapêutica da doença variam conforme sua apresentação clínica e gravidade, bem como o impacto na qualidade de vida do portador. A terapia biológica vem se tornando uma das principais classes utilizadas no contexto desta enfermidade, mas não está claro quando deve ser iniciada ou em que momento a própria doença deve ser considerada moderada ou grave. Sua forma de apresentação multiforme dificulta a classificação dos pacientes nestes grupos. Neste trabalho, foi realizada revisão de literatura sobre a introdução de terapia biológica como tratamento da doença inflamatória intestinal em curso. (AU)


Crohn's Disease (CD) is an inflammatory disease that can affect any portion of the gastrointestinal tract, caused by immune dysregulation, managed by endogenous and exogenous factors. The forms of therapeutic approach of the disease vary significantly according to its clinical presentation and severity, as well as to the impact on patient's quality of life. Biologic therapy has become one of the main classes used in the context of this disease; however, when it should be initiated or at what time the disease itself should be considered moderate or severe is not clear. Its multiform presentation makes it difficult to classify patients in these groups. In this work, a literature review was carried out about the introduction of the biologic therapy as a treatment of the ongoing inflammatory bowel disease. (AU)

ABSTRACT

Background: Although immunosuppressive therapies have made organ transplantation a common medical procedure worldwide, chronic toxicity has a major issue for long-term treatment. One method to improve therapies and methods is the application of immunomodulatory agents from parasites such as Hypoderma lineatum. Hypodermin A (HA) is a serine esterase secreted by the larvae of Hypoderma lineatum, several studies demonstrated its immunosuppressive mechanism in vitro, and recently we discovered that HA inhibits the expression of interferon (IFN)-γ and interleukin (IL)-2 and activates IL-10 expression. Therefore, we hypothesized that it might be a potential agent used to block allograft rejections. However, most studies of the immunosuppressive mechanisms associated with HA were undertaken at the cellular level. In order to augment these studies, we evaluated the immunosuppressive effects of HA in vivo using an HA transgenic mouse model. Result: Our results revealed similar findings to those reported by in vitro studies, specifically that HA induced prostaglandin E2 expression, downregulated IFN-γ and IL-2 expression, and promoted IL-10 secretion via E-type prostanoid receptor 4. Additionally, we observed that HA overexpression inhibited lipopolysaccharide-induced TLR4 activation. These findings provide insight into a new potential agent capable of blocking graft rejection. Conclusion: Our founding suggested that HA-related treatment could be a promising option to improve the viability of grafts in human.
