Biofilms, aggregates of bacteria enclosed in a self-produced matrix, have been implicated in various pediatric respiratory infections, including acute otitis media (AOM), otitis media with effusion (OME), adenoiditis, protracted bacterial bronchitis, and pulmonary exacerbations in cystic fibrosis. These infections are prevalent in children and often associated with biofilm-producing pathogens, leading to recurrent and chronic conditions. Biofilms reduce antibiotic efficacy, contributing to treatment failure and disease persistence. This narrative review discusses biofilm production by respiratory pathogens such as , non-typeable , , and . It examines their mechanisms of biofilm formation, antibiotic resistance, and the challenges they present in clinical treatment. Various antibiofilm strategies have shown promise in vitro and in animal studies, including the use of N-acetylcysteine, enzymes like dispersin B, and agents disrupting quorum sensing and biofilm matrix components. However, their clinical application, particularly in children, remains limited. Traditional treatments for biofilm-associated diseases have not significantly evolved, even with biofilm detection. The transition from experimental findings to clinical practice is complex and requires robust clinical trials and standardized biofilm detection protocols. Addressing biofilms in pediatric respiratory infections is crucial for improving treatment outcomes and managing recurrent and chronic diseases effectively.
生物膜是包裹在自身产生的基质中的细菌聚集体,与多种小儿呼吸道感染有关,包括急性中耳炎(AOM)、分泌性中耳炎(OME)、腺样体炎、迁延性细菌性支气管炎以及囊性纤维化的肺部加重。这些感染在儿童中很常见,并且常常与产生生物膜的病原体相关,导致复发和慢性疾病。生物膜会降低抗生素疗效,导致治疗失败和疾病持续存在。这篇叙述性综述讨论了呼吸道病原体如非分型、、和产生生物膜的情况。它研究了它们形成生物膜的机制、抗生素耐药性以及它们在临床治疗中带来的挑战。各种抗生物膜策略在体外和动物研究中已显示出前景,包括使用N - 乙酰半胱氨酸、像分散素B这样的酶以及破坏群体感应和生物膜基质成分的药物。然而,它们在临床中的应用,尤其是在儿童中的应用仍然有限。即使有生物膜检测,针对生物膜相关疾病的传统治疗方法也没有显著进展。从实验结果向临床实践的转变很复杂,需要强有力的临床试验和标准化的生物膜检测方案。解决小儿呼吸道感染中的生物膜问题对于改善治疗效果和有效管理复发和慢性疾病至关重要。
