【摘要】

背景和目的:有不多的研究对如何有效治疗非酒精性脂肪肝进行了相应的论述。在这里,我们主要评估奥利司他对非酒精性脂肪肝的疗效。

方法:通过随机、双盲、安慰剂对照等方法对52例非酒精性脂肪肝患者进行研究,其中52例患者通过超声检验,其中40例患者通过肝活检进行确认。这些患者被随机分配服用奥利司他6个月(120mg,每日3次)或安慰剂。除此以外,所有的患者参与相同的减肥计划,每个月所有患者都要检查腹部超声、肝酶水平、血脂水平、胰岛素水平以及人体体格参数等,所有患者接受营养后续评估。22名患者在结束后接受肝活检检查。

结果:52名招募的患者中,44名(平均年龄47.7岁,平均BMI指数为33)的患者完成了研究。其中奥利司他组中,血糖、血脂水平更为显著,同时肝纤维化水平也有一定的升高。两组中BMI指数均显著降低,但两组间无明显差异。两组中血浆谷丙转氨酶均显著降低,但奥利司他组较对照组降低了近2倍(48%vs26.4%)。只有奥利司他组在统计学上有显著逆转脂肪肝的作用。

结论:根据超声波诊断结果分析,奥利司他除了能够减少非酒精脂肪肝患者的体重以外,还能够改善其血浆中的ALT浓度水平

ABSTRACT

Background & Aims:  Few controlled studies have addressed the issue of effective medical treatment for nonalcoholic fatty liver disease (NAFLD). We herein assessed the effect of orlistat in patients with NAFLD.

 Methods: We performed a randomized, double-blind, placebo-controlled study on 52 patients with NAFLD diagnosed by ultrasound (US) and confirmed by liver biopsy (40 patients). The patients were randomized to receive either orlistat (120 mg 3 times daily for 6 months) or placebo. All patients participated in an identical behavioral weight loss program. All patients underwent monthly evaluation by abdominal US; liver enzyme levels, lipid profiles, insulin levels, and anthropometric parameters were monitored, and all patients underwent nutritional follow-up evaluation. Twenty-two patients underwent a second liver biopsy examination at the end of the study.

Results: Fifty-two patients were recruited and 44 (mean age, 47.7 y; mean body mass index, 33) completed the study. Serum glucose and insulin levels (P < .03) were significantly higher in the orlistat group, which also presented a higher degree of fibrosis. Body mass index was reduced significantly in each group, with a nonsignificant difference between the groups. Serum alanine transaminase (ALT) levels decreased significantly in both groups, with an almost 2-fold reduction in the orlistat group (48% vs 26.4%). There was a statistically significant reversal of fatty liver by US only in the orlistat group (P < .05).

Conclusions: Orlistat improves serum ALT levels and steatosis on US in NAFLD patients, beyond its effect on weight reduction.
