从临床试验结果谈替比夫定的慢性乙型肝炎治疗路线图

“路线图”的概念根据以替比夫定为代表的核苷类药物治疗过程中HBVDNA下降的幅度与出现耐药性病毒突变明显相关的现象提出的。其核心内容是治疗后12周～24周的病毒学效应,对于预测和评估疗效具有重要意义。本文通过对“路线图”的概念、替比夫定“路线图”的临床试验依据及意义的介绍,阐明替比夫定治疗后12～24周的病毒学效应,对于预测和评估疗效具有重要意义;“路线图”对慢性乙型肝炎患者应用替比夫定治疗过程中调整治疗策略的指导意义,以规范临床治疗行为,规避耐药发生。     

慢性乙型肝炎治疗路线图的评价——应答指导的临床治疗策略

慢性乙型肝炎治疗路线图是根据患者对抗病毒药物应答的不同、用病毒及其抗原水平在治疗的整个过程中对患者进行科学管理、制定治疗策略、确定治疗时间的一种优化治疗方案。本文将从它的可行性和意义、重要性、治疗策略的确定及在临床上应用的局限性等方面进行论述。     

慢性乙肝治疗路线图和HBV DNA、HBeAg、HBsAg定量的监测意义

慢性乙型肝炎病毒感染呈世界分布并且引起不良结局,是极为严重的健康问题。慢性乙型肝炎治疗最重要的目标是长期抑制病毒以改善预后,防止出现肝硬化、肝衰竭和肝癌。目前,抗病毒药物主要有干扰素和口服核苷（酸）类似物,核苷（酸）类似物的缺点主要在于长期治疗中出现耐药。路线图概念被用于监测耐药预测疗效。HBV DNA定量水平被作为路线图较好的监测指标。由于血清转换率及清除率过低,HBeAg、HBsAg定量检测不适合用于路线图监测,但对于使用聚乙二醇干扰素的慢性乙肝患者,可作为预测治疗应答的指标。     

The NIH Roadmap: Are Psychologists In or Out?

Psychologists often express concerns about the inclusion of psychology in the National Institutes of Health (NIH) Roadmap initiative. Most Roadmap themes focus on biomedical research, forming the basis for psychologists’ concerns. Although most Roadmap funding goes toward biomedical research, social and behavioral scientists do win support. It is reasonable to ask, however, why the Roadmap is focused so exclusively on medical research. One explanation is that medical interventions are seen as the natural translation of basic biomedical research, whereas psychological interventions are not perceived as following from basic behavioral research. Psychologists working in academic health centers represent the best opportunity for creating such linkages, and therefore the best potential bridge for psychology connecting to the NIH Roadmap. This paper represents the views of the author, and not necessarily those of the American Psychological Association and is based on a presentation given at the 3rd National Conference of the Association of Psychologists in Academic Health Centers in May 2007 in Minneapolis, Minnesota.
