RESUMO

The Global Alliance against Chronic Respiratory Diseases (GARD) is a network of organizations coordinated by the World Health Organization. It is a voluntary alliance of national and international organizations, institutions and agencies with global scope that are committed with actions to improve access to prevention, care and essential medications. On its last annual meeting, celebrated in Brussels (Belgium) in September 2017, the need for actions and representation to be grouped by geographic regions was discussed. There are several successful programs regarding morbidity and mortality control of these diseases, and others that improve cost-benefit and quality of life. Thus, SLaai proposes to contribute to the diffusion and knowledge of chronic respiratory diseases magnitude and risk factors, to identify successful programs in Latin America in order for them to be replicated in the region and to generate strategic alliances for the strengthening of joint actions.


La Alianza Global contra las Enfermedades Respiratorias Crónicas es una red de organizaciones coordinadas por la Organización Mundial de la Salud. Es una coalición voluntaria de organizaciones, instituciones y organismos nacionales e internacionales con alcance mundial comprometidos con acciones para mejorar el acceso a la prevención, asistencia y medicamentos esenciales. Durante su última reunión anual, efectuada en Bruselas, Bélgica, en septiembre de 2017, emergió la necesidad de agrupar acciones y representación por regiones geográficas. Existen diferentes programas exitosos en el control de la morbimortalidad de estas enfermedades y otros que mejoran el costo-beneficio y la calidad de vida. Así, desde SLaai se propone contribuir a la difusión y conocimiento de la magnitud y factores de riesgo en enfermedades respiratorias crónicas, identificar programas exitosos de Latinoamérica para ser replicados en la región y generar convenios estratégicos para el fortalecimiento de acciones conjuntas.

RESUMO

Background: One of the greatest challenges for medicine is to find a safe and effective treatment for immune-related diseases. However, due to the low efficacy of the treatment available and the occurrence of serious adverse effects, many groups are currently searching for alternatives to the traditional therapy. In this regard, the use of human mesenchymal stem cells (hMSCs) represents a great promise for the treatment of a variety of immune-related diseases due to their potent immunomodulatory properties. The main objective of this study is, therefore, to present and summarize, through a systematic review of the literature, in vivo studies in which the efficacy of the administration of hMSCs for the treatment of immune-related diseases was evaluated. Methods: The article search was conducted in PubMed/MEDLINE, Scopus and Web of Science databases. Original research articles assessing the therapeutic potential of hMSCs administration for the in vivo treatment immune-related diseases, published from 1984 to December 2017, were selected and evaluated. Results: A total of 132 manuscripts formed the basis of this systematic review. Most of the studies analyzed reported positive results after hMSCs administration. Clinical effects commonly observed include an increase in the survival rates and a reduction in the severity and incidence of the immune-related diseases studied. In addition, hMSCs administration resulted in an inhibition in the proliferation and activation of CD19+ B cells, CD4+ Th1 and Th17 cells, CD8+ T cells, NK cells, macrophages, monocytes, and neutrophils. The clonal expansion of both Bregs and Tregs cells, however, was stimulated. Administration of hMSCs also resulted in a reduction in the levels of pro-inflammatory cytokines such as IFN-γ, TNF-α, IL-1, IL-2, IL-12, and IL-17 and in an increase in the levels of immunoregulatory cytokines such as IL-4, IL-10, and IL-13. Conclusions: The results obtained in this study open new avenues for the treatment of immune-related diseases through the administration of hMSCs and emphasize the importance of the conduction of further studies in this area.

RESUMO

Since the early 19th century, host-defense peptides (HDPs) have been known to play a crucial role in innate host defense. Subsequent work has demonstrated their role in adaptive immunity as well as their involvement in cancer and also a number of inflammatory and/or autoimmune diseases. In addition to these multiple functional activities, several studies have shown that HDP accumulation might be correlated with various human diseases and, therefore, could be used as a biomarkers for such. Thus, research has aimed to validate the clinical use of HDPs for diagnosis, prognosis, and further treatment. In this review, we outline the most recent findings related to the use of HDPs as biomarkers, their clinical and epidemiological value, and the techniques used to determine the levels of HDPs.

RESUMO

Biologics are increasingly being used to modify the course of immune-mediated inflammatory diseases. Some main agents are monoclonal antibodies and a fusion-protein that target TNF. This group includes adalimumab, infliximab, certolizumab pegol, golimumab and etanercept. Although the efficacy of anti-TNFs is supported by numerous randomized clinical trials, their pharmacokinetics depend on many factors, in particular immunogenicity, which can cause marked and rapid clearance and a consequent decrease in efficacy. Kinetics involve receptors that recognize the Fc fragment of the antibody and are responsible for various processes. Pharmacological advances permit optimizing the pharmacokinetics of anti-TNFs. In this review, we examine the kinetics of anti-TNF biologics, and consequent therapeutic implications, and overview some latest developments in the field.

RESUMO

BIT's 1st Annual World Congress of Immunodiseases and Therapeutics was held in Beijing, China, on 15-17 May 2010. The meeting provided a venue for a wide spectrum of researchers in the basic sciences and clinical areas to present and share their data and ideas. The pervading theme of the meeting dealt with the concept that immune mechanisms underlie most, if not all, medical diseases and therefore the future of medical therapeutics necessitates a greater understanding and corrective manipulation of dysfunctional metabolic and immune pathways. The meeting was well run, educational and enjoyable.

RESUMO

Alloimmunization is the formation of antibodies when there is an exposition of the individual to non-self antigens, as it occurs, for example, in the transfusion of incompatible blood and pregnancies, in whom the fetus express in its sanguineous cells antigens exclusively of paternal origin. This article is restricted to the alloimmunization against erythrocytes antigens in obstetric patients. Almost all the anti-erythrocytes antibodies can be fit in one of the 29 systems of already recognized sanguineous groups, being more implied in the hemolytic disease of the newborn anti-D, anti-c and anti-Kell, followed by anti-C, anti-E, anti e, anti-Fy feminine and anti-Jk feminine. The research of irregular antibodies, to permit the diagnosis of alloimmunizated people, and the modern genetic techniques have better characterized these patients for the prophylaxis and prenatal segment. The traditional accompaniment of the gestations of risk for hemolytic disease of the newborn, with the spectral analysis of the amniotic liquid and the intraperitoneal transfusion, has being quickly substituted for the Doppler ultrasound evaluation in the middle cerebral artery, the intravascular transfusion guided for ultrasonography in real time, beyond improvements in the materials and the quality of the blood, that in set, have raised the survival of the attempting fetus. Doubtlessly, the correct application of the prophylaxis with use of anti-D is successful with potential to reduce the alloimmunization cases.

RESUMO

Aloimunização é a formação de anticorpos quando há a exposição do indivíduo a antígenos não próprios, como ocorre, por exemplo, na transfusão de sangue incompatível e nas gestantes, cujos fetos expressam em suas células sanguíneas antígenos exclusivamente de origem paterna. Este artigo se restringe à aloimunização contra antígenos eritrocitários em pacientes obstétricas. Quase todos os anticorpos antieritrocitários podem ser enquadrados em um dos 29 sistemas de grupos sanguíneos já reconhecidos, sendo os mais comumente implicados na doença hemolítica perinatal o anti-D, anti-c e anti-Kell, seguidos por anti-C, anti-E, anti e, anti-Fyª e anti-Jkª. A pesquisa de anticorpos irregulares permite o diagnóstico de indivíduos aloimunizados e modernas técnicas genéticas têm melhor caracterizado estas pacientes para a profilaxia e segmento pré-natal. O tradicional acompanhamento das gestações de risco para a doença hemolítica perinatal, com a espectrofotometria do líquido amniótico e a transfusão intraperitoneal, vem rapidamente sendo substituído pela doplervelocimetria na artéria cerebral média e a transfusão intravascular guiada por ultrassonografia em tempo real. É possível também citar como avanços melhorias nos materiais e na qualidade do sangue transfundido, que, em conjunto, têm elevado a sobrevivência de fetos acometidos. Indubitavelmente, a correta aplicação da profilaxia com uso do anti-D é exitosa com potencial para reduzir os casos de aloimunização.
