近日,一项来自华盛顿大学医学院的最新研究发现,一种糖尿病治疗药物对于HIV病人除具有降糖作用,还能够降低炎症预防心血管疾病的发生。这项研究发表在国际学术期刊JCEM。
 
感染HIV的病人如同得到死亡判决,他们发生心脏衰竭、糖尿病以及其他与葡萄糖、胰岛素和胆固醇有关的代谢疾病的风险都将大大增加,其中一个重要的推动因素是慢性炎症。
 
在该项研究中,研究人员发现降糖药物西他列汀对进行抗逆转录病毒治疗的HIV阳性病人具有改善代谢,降低炎症的双重作用。服用该药物的病人其血糖发生下降,一些免疫激活和炎症发生的标记物也发生表达下降,这表明西他列汀可能对病人的心脏、骨和肝脏提供了长时间的保护作用。
 
这项研究是该研究团队对西他列汀治疗HIV病人的第二次研究,在前一次研究中,研究人员对西他列汀的安全性进行了探究,而这一次他们将研究重点放在了西他列汀的功能研究上。在这项为期8周的研究过程中,研究人员将年龄在18-65岁的36名HIV病人分为两组,一组给予西他列汀治疗,另一组给予安慰剂,并对他们的血糖水平、胰岛素敏感性、脂质水平、免疫细胞数量、炎症标记物和其他健康指标进行了连续观察,这些病人在实验期间都接受了抗逆转录病毒治疗,并且他们免疫状态都比较稳定。
 
最终,研究人员发现服用西他列汀的HIV病人其血糖得到了有效控制,并且炎症以及免疫激活标记物都发生了下降,表明西他列汀不仅可以改善糖尿病症状,还可以对HIV病人的免疫状态进行调节。虽然这一发现仍需进一步的长期临床验证,但仍然证明西他列汀是一种具有很好应用前景的药物。
