Macrolides are drugs that have antimicrobial effects, especially against intracellular pathogens. Various studies have shown that macrolides might also have anti-inflammatory effects. Macrolides inhibit the production of interleukins and can reduce pulmonary neutrophilic inflammation. Clinical trials have demonstrated beneficial effects of macrolides in various chronic lung diseases. The objective of this study was to review recent data in the medical literature on the anti-inflammatory effects of macrolides in childhood lung diseases by searching the Medline (PubMed) database. We used the following search terms: "macrolide and cystic fibrosis"; "macrolide and asthma"; "macrolide and bronchiolitis obliterans"; and "macrolide and acute bronchiolitis". We selected articles published in international scientific journals between 2001 and 2012. Clinical studies and in vitro evidence have confirmed the anti-inflammatory effect of macrolides in respiratory diseases. Some clinical trials have shown the benefits of the administration of macrolides in patients with cystic fibrosis, although the risk of bacterial resistance should be considered in the analysis of those benefits. Such benefits are controversial in other respiratory diseases, and the routine use of macrolides is not recommended. Further controlled clinical trials are required in order to assess the efficacy of macrolides as anti-inflammatory drugs, so that the benefits in the treatment of each specific clinical condition can be better established.Keywords: Macrolides; Asthma; Cystic Fibrosis; Bronchiolitis. ResumoOs macrolídeos são fármacos com efeitos antimicrobianos especialmente contra patógenos intracelulares. Vários estudos têm demonstrado possíveis efeitos anti-inflamatórios dos macrolídeos. Esses medicamentos inibem a produção de algumas interleucinas e podem reduzir a inflamação neutrofílica pulmonar. Ensaios clínicos têm demonstrado efeitos benéficos dos macrolídeos em diversas doenças pulmonares crônicas. O objetivo deste estudo foi revisar os dados recentes da literatura médica sobre os efeitos anti-inflamatórios dos macrolídeos nas doenças respiratórias da infância, através da pesquisa da base de dados Medline (PubMed) dos seguintes termos em inglês: "macrolide and cystic fibrosis"; "macrolide and asthma"; "macrolide and bronchiolitis obliterans"; e "macrolide and acute bronchiolitis" Foram selecionados artigos publicados em revistas científicas internacionais entre 2001 e 2012. Estudos clínicos e evidências in vitro comprovam o efeito anti-inflamatório dos macrolídeos em doenças respiratórias. Alguns ensaios clínicos demonstram benefícios na administração de macrolídeos em pacientes com fibrose cística; porém, o risco de resistência bacteriana deve ser considerado na análise desses benefícios. Tais benefícios são controversos em outras doenças respiratórias, e seu uso rotineiro não está indicado. Mais estudos clínicos controlados são necessários para avaliar a eficácia desses medicamentos como anti-inflamatórios. Dessa forma, poderemos d...
We have found that the patterns of innate and adaptive immune responses at 3 years of age were not affected by the fact of the children having being born preterm or at term.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
