To determine whether cholecystokinin-octapeptide (CCK-OP) would prevent or ameliorate parenteral nutrition-associated cholestasis (PNAC) among high-risk neonates treated with total parenteral nutrition.
This was a multicenter, double-blind, randomized, controlled trial conducted between 1996 and 2001.
Neonates at risk for the development of PNAC included very low birth weight neonates and those with major surgical conditions involving the gastrointestinal tract.
Tertiary care hospitals.
Patients were randomized to receive CCK-OP (0.04 mug/kg per dose, twice daily) or placebo. Eligible infants were all <30 days of age. Patients were enrolled within 2 weeks after birth or within 7 days after surgery.
The primary outcome measure was conjugated bilirubin (CB) levels, which were measured weekly. Secondary outcome measures included incidence of sepsis, times to achieve 50% and 100% of energy intake through the enteral route, number of ICU and hospital days, mortality rate, and incidences of biliary sludge and cholelithiasis.
A total of 243 neonates were enrolled in the study. CCK-OP administration did not significantly affect CB levels (1.76 +/- 3.14 and 1.93 +/- 3.31 mg/dL for CCK-OP and placebo groups, respectively; mean +/- SD). Secondary outcome measures also were not significantly affected by the study drug.
Use of CCK-OP failed to reduce significantly the incidence of PNAC or levels of CB. CCK-OP had no effect on other secondary measures and should not be recommended for the prevention of PNAC.
确定在接受全胃肠外营养治疗的高危新生儿中,胆囊收缩素八肽(CCK-OP)是否能预防或改善胃肠外营养相关胆汁淤积(PNAC)。
这是一项于1996年至2001年间进行的多中心、双盲、随机对照试验。
有发生PNAC风险的新生儿包括极低出生体重儿以及患有涉及胃肠道的重大外科疾病的新生儿。
三级医疗机构。
患者被随机分配接受CCK-OP(每剂0.04微克/千克,每日两次)或安慰剂。符合条件的婴儿均小于30日龄。患者在出生后2周内或手术后7天内入组。
主要观察指标是结合胆红素(CB)水平,每周测量一次。次要观察指标包括败血症发生率、通过肠内途径达到能量摄入量50%和100%的时间、重症监护病房(ICU)住院天数和总住院天数、死亡率以及胆泥和胆结石的发生率。
共有243名新生儿纳入本研究。给予CCK-OP对CB水平无显著影响(CCK-OP组和安慰剂组分别为1.76±3.14和1.93±3.31毫克/分升;均值±标准差)。研究药物对次要观察指标也无显著影响。
使用CCK-OP未能显著降低PNAC的发生率或CB水平。CCK-OP对其他次要指标无作用,不建议用于预防PNAC。
