Diabetes Care:苯丁胺与托吡酯缓释剂可有效预防2型糖尿病

2014-04-29 佚名 dxy

随着2型糖尿病患病率逐年上升,患者和社会负担也在逐年加重,当前急需一种能有效防治2型糖尿病的治疗策略。既往研究发现苯丁胺与托吡酯缓释剂(PHEN/TPM ER)联合生活方式干预可显著降低超重/肥胖患者的体重,然而,苯丁胺与托吡酯缓释剂对2型糖尿病进展的影响仍不清楚。 为此,来自美国伯明翰退伍军人医疗中心的Garvey教授及其团队进行了一项研究,在糖尿病前期和代谢综合征患者中,探讨108周苯丁胺与

随着2型糖尿病患病率逐年上升,患者和社会负担也在逐年加重,当前急需一种能有效防治2型糖尿病的治疗策略。既往研究发现苯丁胺与托吡酯缓释剂(PHEN/TPM ER)联合生活方式干预可显著降低超重/肥胖患者的体重,然而,苯丁胺与托吡酯缓释剂对2型糖尿病进展的影响仍不清楚。

为此,来自美国伯明翰退伍军人医疗中心的Garvey教授及其团队进行了一项研究,在糖尿病前期和代谢综合征患者中,探讨108周苯丁胺与托吡酯缓释剂治疗对其2型糖尿病和心血管代谢疾病进展的影响。该研究结果发表在2014年04月的Diabetes care杂志上。

该研究是苯丁胺与托吡酯缓释剂的一项随机、双盲、安慰剂对照、Ⅲ期临床试验亚组分析, 在伴有两种或两种以上合并症的超重/肥胖受试者(27≤BMI≤45kg/m2)中进行。受试者被随机分到接受安慰剂、苯丙胺7.5mg/ 托吡酯缓释剂46mg(7.5/46)或苯丙胺15mg/托吡酯缓释剂92mg(15/92)联合生活方式改变治疗108周。使用多元计算法(ITT–MI)评估意向治疗人群体重下降百分比、进展为2型糖尿病的年发生率、以及其血糖、血脂参数、血压和腰围的变化。

该研究中,在基线,共有475例受试者符合糖尿病前期或代谢综合征的诊断标准。108周治疗后,安慰剂组、7.5/46组、15/92组糖尿病前期和代谢综合征患者平均体重下降百分比分别为2.5%、10.9%和12.1%。与安慰剂组相比,接受7.5/46和15/92治疗的受试者2型糖尿病年发生率分别下降70.5%和78.7%。苯丁胺与托吡酯缓释剂预防糖尿病的能力与体重下降程度有关,而且,苯丁胺与托吡酯缓释剂治疗可明显改善心脏代谢参数。在这个亚组分析,苯丁胺与托吡酯缓释剂治疗2年耐受性良好。

该研究提示,在合并糖尿病前期和代谢综合征的超重/肥胖患者中,苯丁胺与托吡酯缓释剂联合生活方式干预可导致患者体重明显下降,显著减少其向2型糖尿病进展,而且,还伴随着多种心血管代谢性疾病危险因素的改善。
