To describe mechanisms by which glucocorticoids cause osteoporosis, with fracture risk, combining this learning with a possible professional behavior change.
A systematic search on SciELO, PubMed, Scopus, and Medline databases was carried out for consensus, review articles, including systematic reviews and meta-analysis, which were published in English, between 2000 and 2016. Keywords used on the search were the following: glucocorticoids, fractures, osteoporosis, bone health, vitamin D, children, and adolescents.
The review was divided into four topics: 1) introduction, with a brief focus on pediatric fractures; 2) osteoporosis in children and adolescents, highlighting it as a silent cause of fractures; 3) glucocorticoids and secondary bone disease, describing deleterious mechanisms of this steroids group on bone structure; 4) molecular effects of glucocorticoids excess on bone, with details about the harmful mechanisms on bone molecular level.
Glucocorticoids excess determines early bone disease, favoring the occurrence of fractures. Thus, a child or an adolescent who uses glucocorticoids, especially systemically and chronically, but also repeats cycles at high cumulative doses of the medication, needs care and guidance related to bone health at the onset of treatment. On the other hand, the presence of fractures, even if related to trauma, can be a sign of underlying and unknown bone fragility, which may be secondary to the use of glucocorticoids and/or vitamin D deficiency.
描述糖皮质激素导致骨质疏松的机制以及骨折风险,并将这些知识与可能的职业行为改变相结合。
对SciELO、PubMed、Scopus和Medline数据库进行了系统检索,以查找2000年至2016年间发表的英文共识、综述文章,包括系统评价和荟萃分析。检索使用的关键词如下:糖皮质激素、骨折、骨质疏松症、骨骼健康、维生素D、儿童和青少年。
该综述分为四个主题:1)引言,简要关注儿童骨折;2)儿童和青少年骨质疏松症,强调其作为骨折的隐匿原因;3)糖皮质激素与继发性骨病,描述该类类固醇对骨骼结构的有害机制;4)糖皮质激素过量对骨骼的分子影响,详细介绍在骨骼分子水平上的有害机制。
糖皮质激素过量会导致早期骨病,增加骨折发生风险。因此,使用糖皮质激素的儿童或青少年,尤其是全身长期使用,且药物累积剂量高且反复用药周期者,在治疗开始时就需要有关骨骼健康的护理和指导。另一方面,即使骨折与创伤有关,也可能是潜在的、未知的骨骼脆弱的迹象,这可能继发于糖皮质激素的使用和/或维生素D缺乏。
