Vibration-Controlled Transient Elastography-Based Parameters Predict Clinical Outcomes in Liver Transplant Recipients. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00590-1. [PMID: 38969073 DOI: 10.1016/j.cgh.2024.06.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 05/12/2024] [Accepted: 06/17/2024] [Indexed: 07/07/2024]
Abstract
BACKGROUND AND AIMS Vibration-controlled transient elastography (VCTE) is used in clinical practice to risk-stratify liver transplant (LT) recipients; however, there are currently little data demonstrating the relationship between VCTE and clinical outcomes. METHODS A total of 362 adult LT recipients with successful VCTE examination between 2015 and 2022 were included. Presence of advanced fibrosis was defined as liver stiffness measurement (LSM) ≥10.5 kPa and hepatic steatosis as controlled attenuation parameter (CAP) ≥270 dB/m. The outcomes of interest included all-cause mortality, myocardial infarction (MI), and graft cirrhosis using cumulative incidence analysis that accounted for the competing risks of these outcomes. RESULTS The LSM was elevated in 64 (18%) and CAP in 163 (45%) LT recipients. The baseline LSM values were similar in patients with elevated vs normal CAP values. After a median follow-up of 65 (interquartile range, 20-140) months from LT to baseline VCTE, 66 (18%) patients died, 12 (3%) developed graft cirrhosis, and 18 (5%) experienced an MI. Baseline high LSM was independently associated with all-cause mortality (hazard ratio [HR], 1.97; 95% confidence interval [CI], 1.11-3.50; P = .02) and new onset cirrhosis (HR, 6.74; 95% CI, 2.08-21.79; P < .01). A higher CAP value was significantly and independently associated with increased risk of experiencing a MI over study follow-up (HR, 4.14; 95% CI, 1.29-13.27; P = .017). CONCLUSIONS The VCTE-based parameters are associated with clinical outcomes and offer the potential to be incorporated into clinical risk-stratification strategies to improve outcomes among LT recipients.

Abstract
BACKGROUND Loss of skeletal muscle can be accompanied by an increase in adipose tissue leading to sarcopenic obesity. There are limited data on how liver transplantation (LT) might impact adipose tissue compartments, particularly among patients with metabolically active disease, such as nonalcoholic steatohepatitis (NASH) and subsequent metabolic sequela. METHODS Skeletal muscle, visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT) were measured using cross-sectional imaging performed in 190 patients pre-LT, 6 mo post-LT and 12 mo post-LT. Changes in adipose tissue and their impact on metabolic diseases were determined in patients transplanted for NASH versus non-NASH. RESULTS Skeletal muscle, VAT, and SAT were similar in patients with NASH and non-NASH pre-LT despite a higher burden of metabolic diseases in patients with NASH. Following LT, no significant differences between skeletal muscle and SAT were observed in the entire cohort and among patients with NASH (versus non-NASH). LT recipients with the highest muscle mass pre-LT were at the greatest risk for muscle loss post-LT. A time-dependent increase in VAT was noted post-LT, which was more robust among patients with a history of NASH cirrhosis. In adjusted multivariate analysis, NASH versus non-NASH was a strong predictor of post-LT increase in VAT (β-coefficient 3.00, P = 0.04). Pre-LT VAT was an independent predictor of post-LT serum triglycerides (β-coefficient 5.49 ± 2.78, P = 0.05) and low-density lipoprotein cholesterol (β-coefficient 1.80 ± 0.75, P = 0.02). A trend between pre-LT VAT and diabetes was noted but did not reach statistical significance. CONCLUSIONS VAT but not SAT increases rapidly after LT, especially among patients transplanted for NASH cirrhosis and predicts future metabolic burden.

Abstract
BACKGROUND & AIMS Cardiovascular disease is the leading cause of mortality in nonalcoholic fatty liver disease (NAFLD). The aim of this study was to evaluate the effects of saroglitazar, a dual peroxisome proliferator-activated receptor α/γ agonist, on serum lipids in patients with NAFLD. METHODS A total of 221 patients (saroglitazar, 130; placebo, 91) with NAFLD from phase 2 and 3 double-blinded placebo-controlled randomized clinical trials were pooled to assess the impact of saroglitazar magnesium 4 mg on traditional lipids, very low density lipoprotein cholesterol (VLDL-C), and small dense LDL-C (sdLDL-C). Change from baseline in lipid parameters was performed by using analysis of covariance including treatment as fixed effect and baseline value, diabetes, hypertension, and statin use as covariates. RESULTS Treatment with saroglitazar significantly improved total cholesterol (-17 mg/dL, 95% confidence interval [CI], -24 to 9; P < .001), triglyceride (-45 mg/dL, 95% CI, -60 to 31; P < .001), low-density lipoprotein cholesterol (-8 mg/dL, 95% CI, -15 to -1; P = .01), and VLDL-C (-8 mg/dL, -14 to -3; P < .001). Saroglitazar improved serum lipids as early as 4-6 weeks of initiation of therapy, and these effects persisted for duration of therapy. Saroglitazar also improved the highly atherogenic sdLDL-C (-10 mg/dL, -17 to -2; P = .01). In subgroup analysis of patients with either diabetes or hypertension, saroglitazar significantly improved serum lipids. CONCLUSIONS Saroglitazar improved the serum atherogenic lipoprotein profile in patients with NAFLD, irrespective of comorbid conditions and statin use. Saroglitazar has the potential to not only positively affect liver disease but also reduce cardiovascular risk in patients with NAFLD.

Abstract
AIM This systematic review and meta-analysis was conducted to evaluate the efficacy and safety of 4 mg saroglitazar treatment in patients with non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH). METHODS PubMed, Embase, Scopus, Cochrane CENTRAL, medRxiv (pre-print), bioRxiv (pre-print), and ClinicalTrials.gov databases were searched for relevant studies. The primary outcome was the change in the serum alanine transaminase (ALT) level. The secondary outcomes were changes in liver stiffness, liver function test parameters, and metabolic parameters. Pooled mean differences were calculated using random-effects models. RESULTS Of 331 studies that were screened, ten were included. Treatment with adjunct saroglitazar showed a reduction in ALT [mean difference: 26.01 U/L (95% CI: 10.67 to 41.35); p = 0.009; i2: 98%; moderate GRADE evidence] and aspartate transaminase [mean difference: 19.68 U/L (95% CI: 8.93 to 30.43); p<0.001; i2: 97%; moderate GRADE evidence] levels. There was a significant improvement in liver stiffness [mean difference: 2.22 kPa (95% CI: 0.80 to 3.63); p = 0.002; i2: 99%; moderate GRADE evidence]. There were significant improvements in glycated hemoglobin [mean difference: 0.59% (95% CI: 0.32 to 0.86); p<0.001; i2: 78%; moderate GRADE evidence], total cholesterol [mean difference: 19.20 (95% CI: 1.54 to 36.87); p = 0.03; i2: 95%; moderate GRADE evidence], and triglyceride [mean difference: 105.49 mg/dL (95% CI: 11.18 to 199.80); p = 0.03; i2: 100%; moderate GRADE evidence] levels. Saroglitazar treatment was safe. CONCLUSION Treatment with adjunct 4 mg saroglitazar could significantly improve liver enzymes, reduce liver stiffness, and improve metabolic parameters (serum glucose and lipid profile) in patients with NAFLD or NASH.

Abstract
Although liver transplantation (LT) recipients are at high cardiovascular risk (CVR), the management of CVR factors (CVRF) after LT is far from optimal and needs to be improved. For this reason, we developed a multidisciplinary protocol to standardize the identification, risk stratification, management, and targets of therapy of CVRF during the first post-LT year. The grade of identification and control of CVRF 12 months after LT in the postintervention cohort (LT January 2018-January 2020, n = 150) were compared with a control cohort who underwent LT between July 2015 and December 2016 (n = 100). Before LT, the prevalence of metabolic-associated fatty liver disease as the indication of LT and the presence of obesity were significantly higher in the postintervention cohort, whereas the prevalence of other CVRF and renal dysfunction tended to be higher. Cyclosporine A was used less frequently in the postintervention cohort, whereas everolimus tended to increase. At 12 months after LT, the proportion of patients with measured blood pressure (88% vs. 56%), glycosilated hemoglobin (HbA1c; 96% vs. 72%), and high-density lipoprotein/low-density lipoprotein cholesterol (67% vs. 33%) was higher in the postintervention than in the control cohort (all p < 0.001). Blood pressure (64% vs. 36%, p = 0.02) and HbA1c (85% vs. 70%, p = 0.1) were within target in more individuals with hypertension and diabetes mellitus, respectively, in the postintervention cohort. Median total cholesterol levels were lower in the postintervention (184 mg/dl; interquartile range [IQR], 160-210 mg/dl) than in the control cohort (212 mg/dl; IQR, 186-240 mg/dl; p = 0.02). At 2 years after LT, the incidence of cardiovascular events was 14% in the control cohort and 6% in the postintervention cohort (p = 0.063). In conclusion, a multidisciplinary, multiprofessional strategy can achieve a higher grade of assessment and management of post-LT CVR despite a worsening metabolic profile of LT recipients.

Abstract
Survival rates after liver transplantation have increased dramatically over the past 20 years. Cardiovascular disease is the most common extra-hepatic cause of mortality in the long-term post liver transplant. This is intimately linked with both the higher pre-existing rates of metabolic syndrome in these patients as well as increased propensity to develop de novo metabolic syndrome post-transplant. This unfavorable metabolic profile that contributes to cardiovascular disease is multifactorial and largely preventable. This review explores metabolic syndrome and cardiovascular disease and their contributory factors post liver transplantation to highlight areas for potential intervention and thus reduce the significant morbidity and mortality of patients due to metabolic syndrome and cardiovascular disease.
