Abstract
BACKGROUND Liver transplant (LT) recipients often experience adverse effects of immunosuppressive (IS) drugs, especially on metabolic profiles. Selected LT recipients can achieve successful IS withdrawal; however, its effects on metabolic syndrome (MS) are unknown. METHODS This is a retrospective single-center study investigating the incidence and/or regression of MS in 75 selected LT recipients who were previously enrolled in prospective IS withdrawal trials between 1999 and 2017. Patients who were transplanted due to nonalcoholic steatohepatitis/metabolic-associated fatty liver disease were excluded, as well as those with a follow-up <3 y after IS weaning. RESULTS Forty-four patients (58.7%) achieved sustained withdrawal or minimization of immunosuppression (WMIS) and 31 patients (41.3%) required reintroduction of immunosuppression (no-WMIS). Among LT recipients who were metabolically healthy (n = 52, 69.3%) before the start of IS weaning, there was a significantly lower rate of de novo MS in WMIS patients compared with no-WMIS patients after 5 y (8.3% and 47.8%, respectively, P = 0.034). Of 23 LT recipients (30.7%) who had MS at the time of commencing IS withdrawal, complete regression of MS was observed in 47.1% of WMIS patients and in none (0%) of the no-WMIS patients after 5 y (P = 0.054). Furthermore, individual components of MS were better controlled in IS-weaned patients, such as arterial hypertension and abnormal serum lipids. CONCLUSIONS Achievement of sustained IS withdrawal reduces the incidence of de novo MS development in metabolically healthy patients and increases the likelihood of MS regression in patients with established MS. The foreseeable long-term beneficial effects of these favorable metabolic changes on morbidity and mortality of LT recipients require further investigation.

Abstract
Liver transplant (LT) recipients require close follow-up with regular monitoring of the liver function tests (LFTs). Evaluation of deranged LFT should be individualized depending upon the time since LT, peri-operative events, clinical course, and any complications. These derangements can range from mild and asymptomatic to severe and symptomatic elevations requiring expedited personalized assessment and management. Pattern of LFT derangement (hepatocellular, cholestatic, or mixed), donor-recipient risk factors, timing after LT (post-operative, 1-12 months, and >12 months since LT) along with clinical context and symptomatology are important considerations before proceeding with the initial evaluation. Compliance to immunosuppression and drug interactions should be ascertained along with local epidemiology of infections. Essential initial evaluation must include an ultrasound abdomen with Doppler to rule out any structural causes such as biliary or vascular complications apart from focussed laboratory evaluation. Early allograft dysfunction, ischemia reperfusion injury, small-for-size syndrome, biliary leaks, hepatic artery, and portal vein thrombosis are usual culprits in the early post-operative period whereas viral hepatitis (acute or reactivation), opportunistic infections, and recurrence of the primary disease are more frequent in the later period. Graft rejection, biliary strictures, sepsis, and drug induced liver injury remain possible etiologies at all times points after LT. Initial evaluation algorithm must be customized based on history, clinical examination, risk factors, and pattern and severity of deranged LFT. Allograft rejection is a diagnosis of exclusion and requires liver biopsy to confirm and assess severity. Empirical treatment of rejection sans liver biopsy is discouraged.

Abstract
Nearly two-thirds of patients with cirrhosis suffer from malnutrition resulting from multiple contributory factors such as poor intake, accelerated starvation, catabolic milieu, and anabolic resistance. Nutritional assessment and optimization are integral to adequate management of a liver transplant (LT) candidate. A detailed nutritional assessment should be done at baseline in all potential transplant candidates with periodic reassessments. Sarcopenia is defined as a reduction in muscle mass, function, and/or performance. Skeletal muscle index at 3rd lumbar vertebra determined by computed tomography is the most objective tool to assess muscle mass. Hand-grip strength and gait speed are simple tools to gauge muscle strength and performance, respectively. Sarcopenia, sarcopenic obesity, and myosteatosis portend poor outcomes. Sarcopenia contributes greatly to frailty, which is a syndrome of reduced physiological reserve and impaired response to stressors. Dietary interventions must ensure adequate calorie (35-40 kcal/kg/day) and protein (1.2-1.5 gm/kg/day) intake via multiple frequent meals and late-evening calorie-dense snack. Micronutrient supplementation is essential, keeping in mind the etiology of cirrhosis. Individualized, gradually up-titrated exercise prescription consisting of both aerobic and resistance training of 150 min/week is advisable after appropriate risk assessment. Early initiation of enteral nutrition within 12-24 h of LT is recommended. Data with respect to immune-nutrition, monomeric formulas, and hormone replacement remain conflicting at present. A multidisciplinary team comprising of hepatologists, transplant surgeons, intensivists, dieticians, and physiotherapists is vital to improve overall nutrition and outcomes in this vulnerable group.

Abstract
Liver transplantation for nonalcoholic fatty liver disease/steatohepatitis (NAFLD/NASH) is increasing rapidly worldwide. Compared with alcohol and viral-related liver disease, NAFLD/NASH is more frequently associated with a systemic metabolic syndrome, which significantly affects other organs, requiring multidisciplinary management, in all phases of liver transplant.

Abstract
Post-transplant metabolic syndrome (PTMS) has been associated with increased cardiovascular risk which significantly impacts the morbidity and mortality rates of liver transplant (LT) recipients. This study sought to conduct a meta-analysis and systematic review on the cumulative incidence, risk factors, and cardiovascular outcomes associated with de novo PTMS.Medline and Embase were searched for articles describing the incidence, risk factors, and cardiovascular outcomes of de novo PTMS. Meta-analysis of proportions was conducted to calculate incidence. Conventional pairwise analysis using random effects model was used to tabulate OR and hazard ratio for risk factors and cardiovascular outcomes, respectively. Fifteen studies involving 2683 LT recipients were included. Overall rate of de novo PTMS was 24.7% (CI: 18.0%-32.9%) over a mean follow-up period of 15.3 months and was highest in patients with NAFLD (60.0%, CI: 52.0%-67.5%) compared with other liver diseases. Older age (OR: 1.05, CI: 1.01-1.09, p = 0.02) and pre-LT type II diabetes mellitus (OR: 5.00, CI: 4.17-5.99, p < 0.01) were predictive factors of de novo PTMS. Patients with de novo PTMS had significantly higher likelihood of cardiovascular disease events compared with those who did not (hazard ratio: 2.42, CI: 1.54-3.81, p < 0.01). De novo PTMS is a common complication and is significantly associated with increased cardiovascular disease morbidity. High-risk patients such as elderly recipients, those with pre-LT type II diabetes mellitus, or NASH-related cirrhosis should undergo routine screening to allow timely intervention.

Front Immunol 2022; 13:944442. [PMID: 36248867 PMCID: PMC9562471 DOI: 10.3389/fimmu.2022.944442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 09/01/2022] [Indexed: 11/20/2022] Open
Abstract
Background Tacrolimus (FK506) is the cornerstone of immunosuppression after liver transplantation (LT), however, clinically, switching from FK506 to cyclosporine (SFTC) is common in LT patients with tacrolimus intolerance. The aim of this study was to investigate the genetic risk of patients with tacrolimus intolerance. Methods A total of 114 LT patients were enrolled in this retrospective study. SNPs were genotyped using Infinium Human Exome-12 v1.2 BeadChip, and genome-wide gene expression levels were profiled using Agilent G4112F array. Results SFTC was a potential risk factor of dyslipidemia (OR=4.774[1.122-20.311], p = 0.034) and insulin resistance (IR) (OR=6.25[1.451-26.916], p = 0.014), but did not affect the survival of LT patients. Differential expression analysis showed donor CYP3A5, CYP2C9, CFTR, and GSTP1, four important pharmacogenetic genes were significantly up-regulated in the tacrolimus intolerance group. Twelve SNPs of these four genes were screened to investigate the effects on tacrolimus intolerance. Regression analysis showed donor rs4646450 (OR=3.23 [1.22-8.60] per each A allele, p = 0.01), donor rs6977165 (OR=6.44 [1.09-37.87] per each C allele, p = 0.02), and donor rs776746 (OR=3.31 [1.25-8.81] per each A allele, p = 0.01) were independent risk factors of tacrolimus intolerance. Conclusions These results suggested that SFTC was a potential risk factor for dyslipidemia and IR after LT. Besides, rs4646450, rs6977165, and rs776746 of CYP3A5 might be the underlying genetic risks of tacrolimus intolerance. This might help transplant surgeons make earlier clinical decisions about the use of immunosuppression.
