床旁超声心动图评估动态心功能、肾脏和心脏生物标志物对肝硬化合并肝肾综合征-急性肾损伤的影响
Point-of-care echocardiography (POC-Echo) is used to determine left ventricular systolic and diastolic dysfunction (LVDD), inferior vena cava (IVC) dynamics and volume status in cirrhosis and Acute-on-chronic liver failure ACLF accurately.
We will assess IVC dynamics, LV systolic function [LV ejection fraction (EF) & cardiac output (CO)], and diastolic dysfunction (E/e', e' and E/A ratio) and urinary biomarkers (cystatin C and NGAL) in patients with cirrhosis and ACLF with hepatorenal syndrome-acute kidney injury (HRS-AKI).

研究人群
Cirrhosis of any etiology, aged between 18-65 years, with hepatorenal syndrome (HRS-AKI).
Acute kidney injury (AKI) (increase in serum creatinine by 0.3 mg/dL in less than 48 hour or an increase in serum creatinine by 50% from a stable baseline reading within 3 months) has been proposed to characterize renal dysfunction in patients with cirrhosis, in which type 1 HRS would be reclassified as HRS-AKI.
Stage 1 AKI would be classified as an increase in serum creatinine level by 0.3 mg/dL or a 50% increase, whereas stages 2 and 3 AKI would be a doubling and tripling, respectively, of serum creatinine levels.

大体时间 |
|---|---|---|
|
Cardiac output measurement by echocardiography
大体时间:Day 0, Day 2, Day 7.
|
Echocardiographic assessment of cardiac output in L/min will be recorded at least 3 time points, day 0 and 48 hours after enrollment. The cardiac output at 7 days after enrollment will also be documented. he Doppler velocity time integral (VTI) method in estimating stroke volume and cardiac output correlates well with results of concurrent thermodilution cardiac output determinations in patients without significant left-sided valvular regurgitation. Cardiac output(CO), Stroke volume (SV), Heart rate (HR) CO = [SV * HR]/ 1000 |
Day 0, Day 2, Day 7.

大体时间:Day 7.
|
IVC maximum and Minimum diameter and collapsibility index determined by percentage change in IVC diameter will be recorded. |
Day 7.
|
|
Number of patients with Complete Response in HRS-AKI
大体时间:Day 7
|
Complete response is defined as a reversal in AKI with a final serum Creatinine (sCr) value of ≤ 0.3 mg/dL of the baseline. |
Day 7
|
|
Number of patients with Partial Response in HRS-AKI
大体时间:Day 7
|
Partial response is defined as regression in the stage of AKI with a final sCr > 0.3 mg/dL above the baseline. |
Day 7
|
|
Number of patients with Non-Response in HRS-AKI
大体时间:Day 7
|
Non-responder is defined if the sCr did not decrease or increased from the baseline. |
