Point-of-care Ultrasonography in Patients with Hepatorenal Syndrome: A Single Center Observational Study.

AIM AND BACKGROUND

A combination of terlipressin and albumin is the standard of care for patients with hepatorenal syndrome-acute kidney injury (HRS-AKI). The study aimed to compare the venous congestion using lung ultrasound score (LUS) and radiographic assessment of lung edema (RALE) scores among terlipressin responders and nonresponders and survivors and non-survivors.

MATERIALS AND METHODS

In this single-center, prospective, observational study, we included adult patients with HRS-AKI who had received terlipressin and albumin from 28th April 2022 to 16th October 2022.

RESULTS

Of the 102 patients included, 74.5% (95%CI: 58.7-93.2) responded to terlipressin. The median dose of terlipressin and albumin was 2 (1-8) mg/day and 100 (40-200) g for a duration of 5 (2-10) days. On Kaplan-Meier analysis, survival was 26.9% of patients in the nonresponder group compared to 61.4% in the responder group ( = 0.001). Day 3 LUS score worsened in 76.9% of patients in nonresponders group compared to 52.6% in responder group ( = 0.03). There was a significant increase in RALE score in those who died [6 (-6-48) vs alive: 0 (-4- 30); < 0.001]. Lung ultrasound score had improved or been maintained in 63.6% of patients who were alive, compared to 14.9% in those who had died ( < 0.001). On multivariable Cox regression analysis, age [HR, 1.02 (1.002-1.05)], terlipressin non-response [HR, 2.8 (1.47-5.34)], APACHE score [HR, 1.07 (1.03-1.12)], duration of terlipressin therapy [HR, 0.37 (0.27-0.5)] and worsening of LUS [HR, 2.9 (1.81-7)] predicted mortality.

CONCLUSION

Lung ultrasound score and chest X-ray can accurately identify venous congestion in the lungs, which is common in patients with advanced liver disease who receive terlipressin and albumin in the intensive care unit (ICU).
