ABSTRACTObjective: To examine adherence to adalimumab (ADA) and etanercept (ETA) and health care costs in rheumatoid arthritis (RA) patients, and to explore the association between adherence, utilization and costs.Research design and methods: Using administrative claims data from a large managed health care plan, RA patients treated with etanercept or adalimumab during the period from 01/01/2005 through 12/31/2005 were identified. The first dispensing date was defined as the index date. Patient adherence and costs were assessed during the 1 year post-index period.Main outcome measures: Nonadherence (medication possession ratio <80%) was modeled using logistic regression. Hazard ratios (HR) comparing time to discontinuation were estimated using Cox proportional hazard (PH) models. Propensity score matching with multivariate generalized linear modeling adjustment was done to assess cost difference between ADA and ETA.Results: Of 3829 eligible RA patients, 1292 (765 existing, 527 naïve) and 2537 (1834 existing, 703 naïve) patients used ADA and ETA, respectively. Compared with ADA users, ETA users had longer average treatment duration (316 vs. 291 days; p?<?0.0001). Unadjusted adherence rates for naïve and existing users were 63% and 70% (ADA), and 65% and 73% (ETA). Logistic regression analysis indicated that compared with ETA users, ADA users were more likely to be nonadherent (OR, naïve 1.24; existing; 1.25). Cox PH models indicated that existing ADA users were more likely to discontinue (HR?=?1.11; p?=?0.06) their medication than existing ETA users. Compared with ADA users, ETA users had significantly lower RA-related pharmacy costs (naïve: $10,892 vs. $12,534, p?<?0.01; existing: $12,192 vs. $13,752, p?<?0.01) and RA-related total costs (naïve: $11,976.42 vs. $13,511.99, p?<?0.05; existing: $14,031 vs. $15,454, p?<?0.05).Conclusions: ETA users had longer treatment duration, were more likely to adhere to their medication regimen and had lower RA-related pharmacy and RA-related total costs compared with ADA users. These findings must be considered within the limitations of this database analysis. 相似文献

脑卒中具有高发病率、高致残率、高死亡率的特点,脑卒中与糖尿病息息相关,二者常伴随发生。近年来发现胰高血糖素样肽-1受体激动剂(GLP-1 receptor agonists, GLP-1 RA)应用于2型糖尿病合并脑卒中的患者可以有效改善其脑血管结局,提示GLP-1 RA在脑卒中的预防和治疗领域存在应用潜力。多项研究表明,GLP-1 RA可以通过降低脑卒中危险因素、保护脑组织、改善认知等机制来发挥其防治作用。本文就GLP-1 RA应用于脑卒中的机制进行综述,并从不良反应的视角探讨合理用药及防治措施。 相似文献

目的通过检测并比较类风湿关节炎、骨关节炎及关节创伤者组滑膜中IPAF1的表达,探讨IPAF和NALP1在类风湿关节炎滑膜中的意义。方法免疫组化检测滑膜衬里层IPAF和NALP1蛋白质表达,于显微镜下观察,随机选取4个视野,连续计数100个位于滑膜衬里层的细胞及其中的阳性细胞数,取平均值,计算阳性细胞率,间接比较蛋白表达。结果滑膜组织免疫组化结果显示:RA组IPAF蛋白表达阳性率大于OA和Trauma组,差异均有统计学意义(P<0.05);NALP1仅在RA组表达,OA和Trauma组未见表达。结论 IPAF和NALP1在RA滑膜组织中有丰富表达,且其表达水平明显高于OA及Trauma组,提示IPAF和NALP1可能参与RA的慢性滑膜炎症过程。 相似文献

In the present study, we aimed to evaluate the anti-inflammatory mechanism of galanthamine, a classic therapeutic drug for Alzheimer’s disease (AD). The co-culture system of hippocampal nerve cell line HT-22 and microglial cell line BV-2 was established to observe the effect of galanthamine on the expressions of inflammatory factors induced by lipopolysaccharide (LPS). MTT method was used to observe the protective effect of galanthamine on neurons. ELISA and qPCR methods were used to detect the expressions of interleukin-1β (IL-1β) and IL-1 receptor antagonist (IL-1RA) at the protein and mRNA levels, respectively. IL-1β and IL-1RA were evaluated by the ELISA method after pretreating with galanthamine and α7 nAChR blocker α-bungarotoxin (α-bun), mAChR blocker atropine (Atr), PI3K inhibitor LY294002, IKKβ inhibitor SC514, or MEK inhibitor PD98059, respectively. The results showed that galanthamine significantly inhibited LPS-induced increased IL-1β and IL-1RA expressions and maintained the ratio of IL-1β/IL-1RA. α-Bun could block the regulatory effect of galanthamine on IL-1β and IL-1RA. As PI3K and NF-κB pathways were blocked, the regulatory effect of galanthamine on the IL-1β expression was significantly inhibited. Blocking PI3K and MEK pathways could significantly inhibit the regulation of galanthamine on IL-1RA expression. In summary, galanthamine regulated the inflammatory activity of the IL-1 subfamily to play an anti-inflammatory role mediated by α7 nAChR and PI3K/NF-κB/MAPK pathways, which probably provided a new strategy for AD treatment. 相似文献
