Predictive value of glucose transporter type 4 for intensive care unit acquired weakness in liver transplantation recipients / 中华器官移植杂志

ABSTRACT

Objective:To seek the biomarkers of diagnostic value for an early postoperative onset of intensive care unit acquired weakness(ICUAW)in liver transplant(LT)recipients.Methods:Between September 2017 and August 2019, A total of 62 consecutive allogeneic orthotopic LT liver transplantation recipients at The First People's Hospital of Kunming between September 2017 and August 2019 are prospectively reviewedenrolled in this study. Upon After entering ICU, blood samples are assayed taken for adenosine 5'-monophosphate-activated protein kinase alpha(AMPK-α)、and glucose transporter type 4(GLUT-4)test. Clinical and bBiochemical specimens are collected. When transplant recipients are during awake and cooperative hours. Their muscle strength is recordedexamined. The score table of Medical Research Council(MRC)is utilized sed as the diagnostic standard of ICUAW. And ICUAW is diagnosed with < 48 points. Based on this, 62 subjects are divided into two groups of ICUAW group(17 cases)and non-ICUAW group (45 cases). The age, sex, mechanical ventilation time, ICU hospitalization time, partial blood oxygen pressure, systolic blood pressure, central venous pressure(CRP), blood glucose, total bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), γ- Glutamyl transpeptidase(γ- GGT), blood urea nitrogen, blood creatinine and levels of AMPK-α and GLUT-4 are compared between patients in ICUAW group and non-ICUAW two groups. and levels of AMPK-α and GLUT-4 were compared between patients in ICUAW group and non-ICUAW two groups. The powers of AMPK-α And and GLUT-4 in predicting ICUAW was were evaluated by receiver operating characteristic curve(ROC)and area under the curve(AUC). Differences with P<0.05 is deemed as significant. Results:ICUAW is diagnosed in 17/62(27.42%)LT recipients. ICUAW patients had longer mechanical ventilation time(27 vs. 10h, P<0.05)and extended ICU hospitalization time(4 vs. 3d, P<0.05). No significant inter-group difference existed in AMPK-α(1.01±2.43 vs. 1.74±4.24 units/ml, 95% CI -2.92~1.45, P>0.05). And the expression of GLUT-4 declined in ICUAW patients(137.86±127.87 vs. 419.15±267.68 ng/L, 95% CI -417.13~-145.45, P<0.05). GLUT-4 ROC curve hint at some negative predictive value for the occurrence of ICUAW. ROC curve area was 0.88 and SE 0.05( P<0.05, 95% CI 0.78~0.98). Conclusions:ICUAW patients have longer mechanical ventilation time and extended ICU hospitalization time. Monitoring GLUT-4 offers some predictive value for ICUAW in LT recipients. Elevated GLUT-4 is associated with a low probability of ICUAW.
