BMC Pediatr 2024; 24:392. [PMID: 38867183 PMCID: PMC11167898 DOI: 10.1186/s12887-024-04831-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Accepted: 05/13/2024] [Indexed: 06/14/2024] Open
Abstract
BACKGROUND Hypoalbuminemia after liver transplantation (LT) is associated with acute kidney injury (AKI) and poor outcomes in adult LT recipients. This study was performed to examine the association between the postoperative serum albumin level and early postoperative outcomes of LT in children. METHODS This single-center retrospective review involved pediatric LT recipients (0-18 years old) treated from January 2013 to June 2020. All patients were admitted to PICU and received standard post-LT care protocol. We divided patients into low (< 30 g/L) and normal (> 30 g/L) groups based on postoperative albumin day 1 to 3. RESULTS Among 108 LT recipients, most had biliary atresia. The median age at the time of LT was 1.8 years [interquartile range (IQR), 1.5-5.7]. There were 18 patients in low albumin group [median albumin level, 27.9 g/L (IQR, 25.8-29.6) and 90 patients in normal albumin group [median albumin level, 34.5 g/L (IQR, 32.4-36.9). The low albumin group had significantly higher incidence of AKI, occurring in 20% of patients with a median onset of 2.5 days following LT (IQR, 1-5). Postoperative hypoalbuminemia (OR, 4.94; 95% CI, 1.32-18.47; p = 0.01) and a longer operative time (OR, 1.37; 95% CI, 1.01-1.47; p = 0.02) were independent risk factors for AKI by multivariable analysis. No significant differences between the two groups were found in other early postoperative outcomes. CONCLUSION Postoperative hypoalbuminemia was associated with early postoperative AKI following LT in children but not with other worsening outcomes.

Qu W, Li X, Huang H, Xie C, Song H. Mechanisms of the ascites volume differences between patients receiving a left or right hemi-liver graft liver transplantation: From biofluidic analysis. COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2022; 226:107196. [PMID: 36367484 DOI: 10.1016/j.cmpb.2022.107196] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 10/17/2022] [Accepted: 10/19/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND AND OBJECTIVE Post-transplant refractory ascites (RA) is common in patients receiving living donor liver transplantation (LDLT) using a left hemi-liver graft than in those using a right hemi-liver graft. However, there is currently no clear mechanism explaining the effect of grafts on ascites drainage. The purpose of this study is to analyze the values of blood flow parameters in the portal vein under different grafts using computational fluid dynamics (CFD) to interpret the relationship between portal pressure values with ascites drainage. METHODS In this work, ascites drainage was counted in 30 patients who underwent left-sided liver transplantation and 26 patients who underwent right-sided liver transplantation. The portal vein flow models of the transplanted liver under different flow rates were established based on computed tomography (CT) images and finite element theory. Ascites drainage and blood flow parameters were qualitatively compared. RESULTS The results show that the ascites drained from patients who received LDLT with a left hemi-liver is three times as that with a right hemi-liver. The simulation results show that the coefficient of the pressure-velocity curve of the left-liver is 1.7 times of the right-liver under the same hydrodynamic conditions, which qualitatively agrees with the clinical data. Moreover, the streamline of the transplanted left liver shows more vortexes compared with the right liver, which is a major reason for the left liver's higher pressure value. CONCLUSION This clinical phenomenon is reproduced and comprehensively explained by the hemodynamic parameters of the portal vein. This work establishes the relationship between portal pressure values and floating water drainage, and offers a new way for physicians to predict postoperative risks intuitively.

Abstract
Data on postoperative chylous ascites (CA) after pediatric liver transplantation (LT) are scarce. This retrospective study was conducted to identify the incidence, risk factors, management, and outcomes of postoperative CA in a large single-center pediatric LT cohort (2000-2016). The study cohort comprised 317 LTs (153 living donors and 164 deceased donors) in 310 recipients with a median age of 2.7 years. The incidence of CA was 5.4% (n = 17), diagnosed after a median time of 10 days after LT. Compared with chylomicron detection in peritoneal fluid (the gold standard), a triglyceride cutoff value of 187 mg/dL in peritoneal fluid showed insufficient sensitivity (31%) for CA diagnosis. In univariate logistic regression analyses, ascites before LT, younger age, and lower weight, height, and height-for-age z score at LT were associated with CA. Symptomatic management of CA included peritoneal drain (100%) and diuretics (76%). Therapeutic interventions included very low-fat or medium-chain triglyceride-rich diets (94%) and intravenous octreotide (6%), leading to CA resolution in all patients. CA was associated with prolonged hospital length of stay (LOS; 40 days in the CA group versus 24 days in the non-CA group; P = 0.001) but not with reduced patient or graft survival rates after a median follow-up time of 14 years. In conclusion, CA in the pediatric LT recipient is a relatively uncommon complication associated with increased hospital LOS and morbidity. Measurement of chylomicrons is recommended in patients with ascites that is more severe or persistent than expected. Dietary interventions are effective in most patients.

Abstract
The following is a short report on the use of a heterozygous (PiMZ) alpha 1 antitrypsin (α1AT) living related donor liver in a homozygous (PiZ) child that was complicated by massive ascites early after transplant. This clinical report is then followed by a brief summary of present knowledge on the α1 AT protein and management of massive ascites in the pediatric liver transplant recipient.
