Abstract

Methods: We included 235 patients with chronic extrahepatic cholestasis due to pancreatic cancer, cholangiocarcinoma, or papillary carcinoma.

Results: GGT was significantly higher in patients without pruritus (median 967, IQR 587-1571) compared to patients with pruritus (median 561 IQR 266-1084 IU/l) (p < 0.01). In contrast, median alkaline phosphatase (AP) was 491 U/L (IQR; 353-684) in patients with pruritus and was not significantly different from 518 U/L (IQR; 353-726) in patients without pruritus (p = 0.524). Direct bilirubin was significantly higher in patients with pruritus compared to patients without pruritus (168 μmol/L (IQR; 95-256) vs. 120 μmol/L (IQR; 56.75-185.5)) (p < 0.01). After correcting for the extent of cholestasis via direct bilirubin, the negative association between GGT and pruritus remained significant and became stronger (p < 0.001).

Conclusion: Serum GGT activity is inversely associated with the presence of cholestatic itch in patients with chronic extrahepatic cholestasis.

-谷氨酰转移酶:对抗胆汁淤积性瘙痒的朋友?肝外胆汁淤积症患者的回顾性观察资料分析。

方法:我们纳入了235例由胰腺癌、胆管癌或乳头状癌引起的慢性肝外胆汁淤积症患者。结果:无瘙痒症患者GGT(中位数967,IQR 587-1571)明显高于瘙痒症患者(中位数561,IQR 266-1084) (p < 0.01)。碱性磷酸酶(AP)中位数为491 U/L (IQR;353-684)，与518 U/L (IQR;353-726)，无瘙痒患者(p = 0.524)。瘙痒患者直接胆红素明显高于无瘙痒患者(168 μmol/L (IQR;95 ~ 256) vs. 120 μmol/L (IQR;56.75-185.5))) (p < 0.01)。通过直接胆红素校正胆汁淤积程度后，GGT与瘙痒之间的负相关仍然显著且变得更强(p < 0.001)。结论:慢性肝外胆汁淤积症患者血清GGT活性与胆汁淤积性瘙痒呈负相关。
