Severe asthma in children is associated with significant morbidity. Children with severe asthma are at increased risk for adverse outcomes including medication-related side effects, life-threatening exacerbations, and impaired quality of life. It is important to differentiate between severe therapy resistant asthma and difficult-to-treat asthma due to comorbidities. The most common problems that need to be excluded before a diagnosis of severe asthma can be made are poor medication adherence, poor medication technique or incorrect diagnosis of asthma. Difficult to treat asthma is a much more common reason for persistent symptoms and exacerbations and can be managed if comorbidities are clearly addressed. Children with persistent symptoms and exacerbations despite correct inhaler technique and good medical adherence to standard Step 4 asthma therapies according to the guidelines, should be referred to an asthma specialist with expertise in severe asthma.
儿童重度哮喘与显著的发病率有关。患有重度哮喘的儿童发生药物相关副作用、危及生命的恶化以及生活质量受损等不良结局的风险增加。区分重度治疗抵抗性哮喘和因合并症导致的难治性哮喘很重要。在做出重度哮喘诊断之前,最常见的需要排除的问题是药物依从性差、用药技术差或哮喘诊断不正确。难治性哮喘是持续症状和恶化的更常见原因,如果合并症得到明确解决,是可以治疗的。对于根据指南接受了标准第 4 步哮喘治疗且吸入器技术正确且药物依从性良好但仍持续存在症状和恶化的儿童,应转介给具有重度哮喘专业知识的哮喘专家。
