Low doses of steroids can inhibit joint damage when used in the early phase of rheumatoid arthritis, according to a new review of evidence.
根据一个新的对证据的综述,在风湿性关节炎的早期使用低剂量的类固醇能够抑制关节损害。
High-quality evidence supports combining the pills with standard medications in the first two years after diagnosis. \"Such treatment should be made readily available to patients,\" say review authors led by John Kirwan of Liverpool Women's Hospital in England.
高度可靠的证据支持在诊断后的头两年联合使用标准的药物治疗。“对于病人,这样的治疗应该很容易的得到,”由英国利物浦的妇女医院的John Kirwan领导的综述作者们认为。
Concern exists about the side effects of steroid therapy, however. High doses can contribute to heart disease, osteoporosis and other complications. Questions remain about whether smaller doses lead to similar problems.
然而,关于类固醇疗法的副作用也得到了考虑。大剂量会导致心脏疾病,骨质酥松和其它的并发症。小剂量是否会导致相同的问题依然存在争论。
Rheumatoid arthritis is a chronic disease in which the body's immune system attacks and destroys healthy joint tissue. The hands and feet are frequently affected, and as the disease progresses it can cause pain, swelling, deformity and disability.
风湿性关节炎是一种身体免疫系统攻击并摧毁健康的关节组织的慢性疾病。手脚经常收到影响,随着病情进展,它能够导致疼痛、肿胀、畸形和残疾。
The steroids studied in the review are known as glucocorticoids and include the well-known anti-inflammatory prednisone. This medication is often prescribed in the first few months after diagnosis to relieve the discomfort of RA until slower-acting drugs begin protecting the joints.
在此综述中得到研究的类固醇是糖皮质激素,包括人所周知的抗炎强的松。在确诊后的头几个月,该药物治疗法就被应用以减轻风湿性关节炎的不适直至缓慢的药效开始保护关节。
Until now, concerns about side effects caused most rheumatologists to \"put people on the lowest possible dose of steroids and get them off it as soon as possible,\" said Scott Zashin, M.D., of the University of Texas Southwestern Medical Center. \"Now, we have to give steroids a little more respect.\"
直至现在,出于对副作用的考虑,大多数的风湿病学家都“只给予患者最低的类固醇的剂量,并尽可能快的停用”,来自德州西南大学医疗中心的Scott Zashin,M.D.说:“ 现在,我们不得不更加重视类固醇了。”
The review appears in the most recent issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.
这篇综述可以在Cochrane数据库最近的一期中找到,该数据库是一个国际化的评价医疗研究的组织――Cochrane联合组织的出版物。在考虑在研的医疗实验的内容和质量后,系统性的综述对医疗实践给出一个基于实证的结论。
The systematic review is based on 15 studies including 1,414 patients. In most of the studies, patients received low doses of glucocorticoid pills along with so-called disease-modifying drugs for one to two years. Periodic X-rays revealed the extent of joint erosion and other signs of damage.
系统性的综述基于15项共1414例患者的研究。病人同时服用低剂量的糖皮质激素药丸和所谓的疾病修饰药物1到2年。周期性X射线显示,关节腐蚀的程度和其它损害的征兆。
All studies except one showed reduced progression of joint damage in patients taking glucocorticoids. When reviewers used statistical methods to focus on only the highest-quality data, the benefits remained statistically significant.
所有的研究除了一个以外,均显示病人的关节损害的程度在服用糖皮质激素后减轻了。当综述者使用统计学方法仅对高质量数据进行分析,益处是有统计学差异的。
\"Even in the most conservative estimate, the evidence that glucocorticoids given in addition to standard therapy can substantially reduce the rate of erosion progression in rheumatoid arthritis is convincing,\" they say.
“甚至在最保守的统计中,在正规疗法之外添加糖皮质激素能够本质上降低风湿性关节炎腐蚀进程的速度,这个证据是令人信服的,”他们说。
The authors say, however, that minimization of joint damage seen on X-rays may not equate to noticeable improvements for patients: \"It does not necessarily follow that patients will gain long-term functional benefit.\" However, two related studies, including one by Kirwan, suggest \"an important link\" between the two.
然而,作者说,在X射线上看到的关节的最小的损害可能不等同于病人显著的改善。“不能够必然的推断病人将会得到长期的功能上的益处。”然而,两个相关的研究,其中之一由Kirwan领导,指出“在两者之间有重要的关联。”
Because of the known health risks associated with intensive steroid use, concern persists regarding long-term use at any level. The authors cite a 2006 systematic review covering the adverse effects of low-dose glucocorticoids, which concluded that \"few of the commonly held beliefs about their incidence, prevalence and impact are supported by clear scientific evidence.\"
由于人所共知的频繁使用类固醇激素所伴随的健康风险,有关任意水平长期使用的担忧一致存在。作者引用2006年的一篇系统综述,该综述涵盖了低剂量糖皮质激素的副作用,其总结道“通常所持有的关于激素的发病率、患病率和影响的观点没有明确的科学证据。”
Moreover, safety data from recent randomized controlled clinical trials of low-dose steroids for RA suggest that negative side effects are \"modest\" and similar to those of sham treatments, say Kirwan and colleagues. Additionally, the most immediate concern -- reduced bone mineral density -- can now be readily treated.
而且,来自最近的对风湿性关节炎使用低剂量类固醇的随机对照临床实验的可靠数据指出,副作用是“温和的”且对于那些假性治疗也一样,Kirwan和他的同事们声称。另外,最直接的担心――骨矿物质密度降低――能被容易的处理。
Nevertheless, potential adverse reactions to glucocorticoid therapy merit further research, say the authors, as does usefulness of steroid treatment for patients who have had rheumatoid arthritis for 3 years or more.
然而,同类固醇疗法对患有风湿性关节炎3年或之上的患者有效一样,糖皮质激素疗法潜在的副作用值得进一步研究,作者说。
Zashin urges patients recently diagnosed with rheumatoid arthritis to see a rheumatologist without delay. Early and aggressive treatment can prevent severe joint damage and disability for most people, he says.
Zashin力劝最近诊断为风湿性关节炎的病人及时去风湿病学家处就诊。早期和进展期治疗能够阻止大多数人严重的关节损害和残疾,他说。
