Abstract
This review discusses long-term complications from immunosuppressants after liver transplantation and the management of these complications. Common complications of calcineurin inhibitors include nephrotoxicity and metabolic diseases. Nephrotoxicity can be managed by targeting a lower drug level and/or adding an immunosuppressant of a different class. Metabolic disorders can be managed by treating the underlying condition and targeting a lower drug level. Gastrointestinal adverse effects and myelosuppression are common complications of antimetabolites that are initially managed with dose reduction or discontinuation if adverse events persist. Mammalian targets of rapamycin inhibitors are associated with myelosuppression, proteinuria, impaired wound healing, and stomatitis, which may require dose reduction or discontinuation. Induction agents and agents used for steroid-refractory rejection or antibody-mediated rejection are reviewed. Other rare complications of immunosuppressants are discussed as well.

Khalid MB, Nagorna A, Rippel N, Ezaz G, Schiano TD, Crismale JF. Early neurologic complications after liver transplant are associated with reduced long-term survival and increased rates of rejection. Liver Transpl 2023; 29:1079-1088. [PMID: 37147847 DOI: 10.1097/lvt.0000000000000172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 04/28/2023] [Indexed: 05/07/2023]
Abstract
Neurologic complications (NCs) are common following liver transplantation (LT) and have been associated with impaired short-term survival. The impact of NC on long-term survival is less defined. We aimed to characterize these outcomes and assess for risk factors for post-LT NC. We performed a single-center, retrospective review of 521 patients with LT from 2016 to 2020. Baseline clinical and laboratory factors, intraoperative events, and outcomes were compared between patients with and without NC. The 5-year overall and rejection-free survival was estimated using the Kaplan-Meier analysis. Multivariable logistic regression assessed for an independent relationship between risk factors and the development of NC. Among 521 LT recipients, 24% experienced post-LT NC. Overall and rejection-free survival at 5 years was, respectively, 69% and 75% among those with NC versus 87% and 88% among those without NC (log-rank < 0.001). Among those who survived the first 3 months after LT, overall survival but not rejection-free survival was reduced among patients with NC. Risk factors for developing NC included peri-LT serum sodium (ΔSNa) ≥ 6 (29.4% vs. 20.5%, p = 0.04), grade 3 or 4 HE pre-LT, SNa < 125 pre-LT, and more intraoperative transfusions. In a multivariable logistic regression model controlling for described variables, SNa < 125 (or 0.21, 95% CI, 0.06-0.74) at LT and pre-LT HE grade 3 or 4 (or 0.45, 95% CI, 0.26-0.76) was independently associated with NC. Long-term survival was reduced among patients who developed NC in the immediate post-transplant period, even when censoring those who died in the first 3 months. Post-LT NC was associated with perioperative ΔSNa ≥ 6. Optimization of SNa pre-LT > 125 and limiting perioperative ΔSNa <6 mEq/L might have a beneficial impact in decreasing NC post-LT, which may improve long-term post-LT survival.

Dynamic evolution of brain structural patterns in liver transplantation recipients: a longitudinal study based on 3D convolutional neuronal network model. Eur Radiol 2023; 33:6134-6144. [PMID: 37014408 DOI: 10.1007/s00330-023-09604-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 02/19/2023] [Accepted: 02/24/2023] [Indexed: 04/05/2023]
Abstract
OBJECTIVES To evaluate the dynamic evolution process of overall brain health in liver transplantation (LT) recipients, we employed a deep learning-based neuroanatomic biomarker to measure longitudinal changes of brain structural patterns before and 1, 3, and 6 months after surgery. METHODS Because of the ability to capture patterns across all voxels from a brain scan, the brain age prediction method was adopted. We constructed a 3D-CNN model through T1-weighted MRI of 3609 healthy individuals from 8 public datasets and further applied it to a local dataset of 60 LT recipients and 134 controls. The predicted age difference (PAD) was calculated to estimate brain changes before and after LT, and the network occlusion sensitivity analysis was used to determine the importance of each network in age prediction. RESULTS The PAD of patients with cirrhosis increased markedly at baseline (+ 5.74 years) and continued to increase within one month after LT (+ 9.18 years). After that, the brain age began to decrease gradually, but it was still higher than the chronological age. The PAD values of the OHE subgroup were higher than those of the no-OHE, and the discrepancy was more obvious at 1-month post-LT. High-level cognition-related networks were more important in predicting the brain age of patients with cirrhosis at baseline, while the importance of primary sensory networks increased temporarily within 6-month post-LT. CONCLUSIONS The brain structural patterns of LT recipients showed inverted U-shaped dynamic change in the early stage after transplantation, and the change in primary sensory networks may be the main contributor. KEY POINTS • The recipients' brain structural pattern showed an inverted U-shaped dynamic change after LT. • The patients' brain aging aggravated within 1 month after surgery, and the subset of patients with a history of OHE was particularly affected. • The change of primary sensory networks is the main contributor to the change in brain structural patterns.

Abstract
BACKGROUND Hyponatremia before liver transplant (LT) increases risk of post-LT neurological complications in patients with decompensated cirrhosis, but it is unknown to what extent change in sodium from pre- to post-LT influences risk of central nervous system (CNS) sequelae. We assessed the relationship between pre- to post-LT delta sodium and prevalence of CNS complications during LT hospitalization. METHODS We performed retrospective single-center chart review of 1265 adults with cirrhosis who underwent LT (2011-2020). Delta sodium is defined as the difference between maximum sodium within 48 h post-LT and lowest sodium within 7 d pre-LT. Primary outcomes are post-LT CNS events during same hospitalization-encephalopathy, delirium, seizure, coma, osmotic demyelination syndrome, or other altered mental status, determined by International Classification of Diseases codes. Secondary outcome is length of hospital stay post-LT (LOS). Logistic regression modeled association between delta sodium and post-LT CNS outcomes; negative binomial regression modeled LOS. RESULTS Median age was 59 y, 36% were female, and median MELD was 20. Median delta sodium was 8 mmol/L (interquartile range, 5-11). 194 (15%) experienced post-LT CNS complications. In multivariable analysis, controlling for confounders including pre-LT hyponatremia, every 5 mmol/L increase in delta sodium associated with 47% greater odds of CNS complication (95% confidence interval, 22%-77%). Delta sodium also associated with 7% increased LOS in adjusted regression (95% confidence interval, 3%-12%). CONCLUSIONS Adult LT recipients with higher perioperative delta sodium shifts displayed a higher risk of post-LT CNS complications, even after adjusting for pre-LT sodium. LT recipients, even those with pre-LT hyponatremia, may benefit from maintenance of stable serum sodium levels to minimize post-LT CNS complications.

Abstract
PURPOSE OF REVIEW Significant advances to our understanding of several neuroinfectious complications after a solid organ transplant (SOT) have occurred in the last few years. Here, we review the central nervous system (CNS) infections that are relevant to SOT via a syndromic approach with a particular emphasis on recent updates in the field. RECENT FINDINGS A few key studies have advanced our understanding of the epidemiology and clinical characteristics of several CNS infections in SOT recipients. Risk factors for poor prognosis and protective effects of standard posttransplant prophylactic strategies have been better elucidated. Newer diagnostic modalities which have broad clinical applications like metagenomic next-generation sequencing, as well as those that help us better understand esoteric concepts of disease pathogenesis have been studied. Finally, several studies have provided newer insights into the treatment of these diseases. SUMMARY Recent findings reflect the steady progress in our understanding of CNS infections post SOT. They provide several avenues for improvement in the prevention, early recognition, and therapeutic outcomes of these diseases.

Abstract
Purpose Calcineurin inhibitors (CNI) can cause long-term impairment of brain function. Possible pathomechanisms include alterations of the cerebral immune system. This study used positron emission tomography (PET) imaging with the translocator protein (TSPO) ligand 18F-GE-180 to evaluate microglial activation in liver-transplanted patients under different regimens of immunosuppression. Methods PET was performed in 22 liver-transplanted patients (3 CNI free, 9 with low-dose CNI, 10 with standard-dose CNI immunosuppression) and 9 healthy controls. The total distribution volume (VT) estimated in 12 volumes-of-interest was analyzed regarding TSPO genotype, CNI therapy, and cognitive performance. Results In controls, VT was about 80% higher in high affinity binders (n = 5) compared to mixed affinity binders (n = 3). Mean VT corrected for TSPO genotype was significantly lower in patients compared to controls, especially in patients in whom CNI dose had been reduced because of nephrotoxic side effect. Conclusion Our results provide evidence of chronic suppression of microglial activity in liver-transplanted patients under CNI therapy especially in patients with high sensitivity to CNI toxicity.

Abstract
RATIONALE Tacrolimus-associated neurologic disorders can be found in some cases, mainly in organ transplantation patients. However, epilepsy induced by tacrolimus in primary membranous nephropathy (PMN) patient is scare. PATIENT CONCERNS A 63-year-old man experienced 1-year history of foamy urine, and edema of lower extremity. DIAGNOSIS The patient had proteinuria, hypoalbuminemia, which indicated nephrotic syndrome. Further, we performed renal biopsy for this patient. Combined with the renal biopsy result, the diagnosis of primary membranous nephropathy was established. INTERVENTION At first, irbesartan was administrated for 6 months. However, the proteinuria had no obvious improvement. Tacrolimus was administrated afterwards. OUTCOMES Twenty-two days after tacrolimus treatment, epilepsy occurred. Sodium valproate and carbamazepine were successively given to control epilepsy. However, the epileptic symptoms were not effectively controlled. During the treatment, the concentration of tacrolimus fluctuated greatly. At last, levetiracetam was given to maintain the curative effect. Fortunately, the patient did not suffer from epilepsy again. The concentration of temporary tacrolimus was stable, whereas proteinuria gradually decreased. LESSONS Tacrolimus-induced epilepsy should be considered in patients exhibiting acute neurological symptoms. Early diagnosis and effective treatment play a vital role for favorable prognosis.

Abstract
Neurological complications are very common after liver transplantation. This study focuses on clinical risk factors and susceptibility gene polymorphisms of neurological complications after liver transplantation. A better predictive model is obtained. This study proves that MTRR is an independent susceptibility gene for neurological complications. Compared with the independent risk factor of abdominal infection, MTRR has a more advantageous value in predicting neurological complications after liver transplantation.

Abstract
Psychotic disorders are a group of psychiatric disorders characterized by the presence of delusions, hallucinations, bizarre behavior, and disorganized speech. There are several possible causes for the occurrence of psychotic disorders in patients who underwent solid organ transplant, including pre-existing mental illness, electrolyte disturbances, infections of the central nervous system, and adverse reaction to drugs. Calcineurin inhibitors are a class of immunosuppressive drugs, such as tacrolimus and cyclosporine, that are currently considered the mainstay in the immunosuppressive drug regimen of patients who underwent solid organ transplant. Neurotoxicity is one of the adverse reactions associated with the use of calcineurin inhibitors, ranging from upper limb tremors to psychotic disorders and seizures. We report the cases of 2 liver transplant recipients who developed severe psychotic disorder 1 month after the procedure. After an extensive investigation for other possible triggers of psychiatric disease, the use of tacrolimus was considered to be the most likely cause for the acute psychotic disorder. In less than 24 hours after suspension of that drug, all symptoms disappeared in both patients, making a causal relationship with tacrolimus even more likely. The patients were then given cyclosporine, another drug from the same class, allowing for adequate immunosuppression and preserved graft function, with no further psychiatric symptoms. This report confirms that a 24-hour trial of tacrolimus suspension can be safe and effective in the diagnosis of drug-related psychotic disorders in patients who underwent liver transplant. This article is compliant with the Helsinki Congress and the Istanbul Declaration.

Abstract
Cognitive dysfunction caused by hepatic encephalopathy (HE) improves within the first year after liver transplantation (LT). However, cognitive restitution seems to be incomplete in a subset of patients and after LT a new-onset cognitive decline was described. Data about the longterm development of cognitive function after liver transplantation (LT) are sparse. This prospective study analyzed whether a history of hepatic encephalopathy (HE) before LT had an impact on the longterm outcome of cognitive function after LT and if patients who underwent LT 5 years earlier showed worse cognitive function than healthy controls. The cognitive function of 34 patients was assessed before LT and at 1 year and 5 years after LT by psychometric tests, including the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and the portosystemic encephalopathy syndrome test, which provides the psychometric hepatic encephalopathy score (PHES). Furthermore, patients completed surveys to assess health-related quality of life (HRQOL). An 22 additional patients were included after LT. Patients were subdivided by having a history of HE before LT. The control group consisted of 55 healthy patients adjusted for age and education. Before LT, patients performed significantly worse than controls in the psychometric tests: RBANS Total Scale (TS), mean ± standard deviation (SD), 92.6 ± 13.3 versus 99.9 ± 12.0, P = 0.01; and PHES, median (interquartile range [IQR]), 0 (-3 to 1) versus 1 (0-2), P < 0.001. At 1 year after LT, patients with a history of HE still showed cognitive impairment compared with controls: RBANS TS, mean ± SD, 89.8 ± 15.1 versus 99.9 ± 12.0, P < 0.01; and PHES, median (IQR), 0 (-2 to 1.25) versus 1 (0-2), P = 0.03. At 5 years after LT, patients with and without a history of HE showed normal cognitive function and improved HRQOL. In conclusion, HE-associated cognitive impairment seems to be reversible within 5 years after LT.

Abstract
Neurologic disturbances including encephalopathy, seizures, and focal deficits complicate the course 10-30% of patients undergoing organ or stem cell transplantation. While much or this morbidity is multifactorial and often associated with extra-cerebral dysfunction (e.g., graft dysfunction, metabolic derangements), immunosuppressive drugs also contribute significantly. This can either be through direct toxicity (e.g., posterior reversible encephalopathy syndrome from calcineurin inhibitors such as tacrolimus in the acute postoperative period) or by facilitating opportunistic infections in the months after transplantation. Other neurologic syndromes such as akinetic mutism and osmotic demyelination may also occur. While much of this neurologic dysfunction may be reversible if related to metabolic factors or drug toxicity (and the etiology is recognized and reversed), cases of multifocal cerebral infarction, hemorrhage, or infection may have poor outcomes. As transplant patients survive longer, delayed infections (such as progressive multifocal leukoencephalopathy) and post-transplant malignancies are increasingly reported.

Abstract
PURPOSE To investigate cerebral microstructural alterations in patients treated with calcineurin inhibitors (CNI) after orthotopic liver transplantation (OLT) using quantitative magnetic resonance imaging (qMRI) and a cross-sectional study design. METHODS Cerebral qMRI was performed in 85 patients in a median 10 years after OLT compared to 31 healthy controls. Patients were treated with different dosages of CNI or with a CNI-free immunosuppression (CNI-free: n = 19; CNI-low: n = 36; CNI-standard: n = 30). T2-, T2*- and T2'- relaxation times, as well as apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were measured in brain gray and white matter by using the regions of interest method. RESULTS In comparison to controls, patients revealed significantly increased T2, T2*, T2', ADC and reduced FA, predominantly in the frontal white matter, indicating microstructural brain alterations represented by increased free water (increased T2), reduced neuronal metabolism (increased T2') and a lower degree of spatial organization of the nervous fibers (reduced FA). CNI-low and CNI-free patients showed more alterations than CNI-standard patients. Analysis of their history revealed impairment of kidney function while under standard CNI dose suggesting that these patients may be more vulnerable to toxic CNI side-effects. CONCLUSION Our findings suggest that the individual sensitivity to toxic side effects should be considered when choosing an appropriate immunosuppressive regimen in patients after liver transplantation.

Abstract
Background In the first weeks after liver transplantation about 30% of the patients develop a posttransplant encephalopathy. A posttransplant encephalopathy comprises metabolic-toxic caused symptoms such as disorientation, confusion, hallucinations, cognitive dysfunction and seizures. We hypothesize that alterations of cerebral metabolites before liver transplantation predispose posttransplant encephalopathy development after liver transplantation. Methods 31 patients with chronic liver disease underwent magnetic resonance spectroscopy (MRS) before liver transplantation to assess glutamine/glutamate (Glx), myo-Inositol (mI), choline (Cho), creatine/phosphocreatine- and N-acetyl-aspartate/N-acetyl-aspartate-glutamate concentrations in the thalamus, lentiform nucleus and white matter. Of these, 14 patients underwent MRS additionally after liver transplantation. Furthermore, 15 patients received MRS only after liver transplantation. Patients’ data were compared to 20 healthy age adjusted controls. Results Patients showed significantly increased Glx and decreased mI and Cho concentrations compared to controls before liver transplantation (p≤0.01). The MRS values before liver transplantation of patients with posttransplant encephalopathy showed no significant difference compared to patients without posttransplant encephalopathy. Patients after liver transplantation showed increased Glx concentrations (p≤0.01) compared to controls, however, patients with and without posttransplant encephalopathy did not differ. Patients with posttransplant encephalopathy who underwent MRS before and after liver transplantation showed a significant mI increase in all three brain regions (p<0.04) and Glx decrease in the lentiform nucleus after liver transplantation (p = 0.04) while patients without posttransplant encephalopathy only showed a mI increase in the thalamus (p = 0.04). Conclusion Patients with and without posttransplant encephalopathy showed no significant difference in cerebral metabolites before liver transplantation. However, the paired sub-analysis indicates that the extent of cerebral metabolite alterations in patients with liver cirrhosis might be critical for the development of posttransplant encephalopathy after liver transplantation.

Abstract
BACKGROUND Calcineurin inhibitor (CNI) neurotoxicity after liver transplantation might be due to impairment of the cerebral metabolism. AIMS To investigate CNI-related alterations of brain metabolite distributions and associations between cognitive function and brain metabolism in patients with long-term CNI treatment after liver transplantation. METHODS Eighty-two patients (19 CNI free, 34 CNI low-dose and 29 standard-dose CNI immunosuppression) 10 years after liver transplantation and 32 adjusted healthy controls underwent nonlocalised brain phosphorus magnetic resonance spectroscopy (MRS) and single voxel proton MRS in the parietal white matter to estimate brain metabolite contents. The MRS results were correlated with psychometric data assessing cognitive function. RESULTS Phosphorus metabolite concentrations with the exception of phosphocreatine (PCr) were reduced in patients compared to controls. Particularly, patients with low-dose CNI therapy showed a significant decrease in adenosine triphosphate (0.209 ± 0.012 vs 0.222 ± 0.010; P < 0.001) and a significant increase in PCr (0.344 ± 0.026 vs 0.321 ± 0.017; P < 0.001) compared to controls. Myo-Inositol in the CNI free group (2.719 ± 0.549 institutional unit [iu]) was significantly lower compared to controls (3.181 ± 0.425 iu; P = 0.02), patients on low-dose (3.130 ± 0.513 iu; P < 0.05) and standard-dose CNI therapy (3.207 ± 0.632 iu; P < 0.02). Glutamate and glutamine levels correlated negatively with cognitive function (Repeatable Battery for the Assessment of Neuropsychological Status Total Scale: R = -0.362, P = 0.029). CONCLUSION Long-term CNI therapy after liver transplantation might be associated with alterations of brain metabolites.

Abstract
Liver transplantation (LT) represents the definitive treatment for end-stage liver disease. Cognitive impairment following LT is frequent, referred to as postliver transplant encephalopathy (PLTE). LT removes the underlying chronic liver disease, and until recently hepatic encephalopathy (HE) was assumed to be fully reversible after LT. However, increasing evidence indicates that some degree of cognitive impairment may be present after LT. To which extent PLTE reflects cognitive impairment caused by residual HE (RHE) or the combined effect of other factors affecting brain function before, during, and after LT is not clarified. None of the available psychometric and neurophysiological tests used for detecting HE is shown to be able to distinguish between etiologies. The available, mostly retrospective, clinical studies indicate a high prevalence of abnormal psychometric tests after LT, and not all seem to recover completely. The patients with earlier HE show the most marked improvements, suggesting that the clinical picture of the early PLTE, in fact, represents RHE. Other early post-LT etiologies for PLTE comprise cerebral ischemia, critical illness encephalopathy, and immunosuppressive therapy. Late-onset etiologies comprise diabetes and hypertension, among others. PLTE regardless of etiology is a worrying issue and needs more attention in the form of mechanistic research, development of diagnostic/discriminative tools, and standardized prospective clinical studies.

Abstract
Orthotopic liver transplantation (LT) remains the only way to definitively cure patients with the most severe liver diseases. Because the survival rate is now fairly high, important questions about neurological sequelae or quality of life after LT have emerged. Indeed, LT represents a peculiar situation because up to 30% of patients present with neurological symptoms after LT compared with only 4% after cardiac transplant and 0.5% after renal transplant. These postoperative neurological symptoms have long been interpreted as sequelae of hepatic encephalopathy (HE). However, postoperative decompensation of an unknown cerebral condition due to the pathophysiology of cirrhosis or undiagnosed neurodegenerative disorders or aging constitute other possibilities that are underrecognized. Some patients who undergo LT for acute liver failure and patients with cirrhosis without episodes of HE and without any previous cerebral alteration also display post-LT neurological symptoms. This latter situation speaks in favor of a direct adverse effect of either general anesthesia, the surgical procedure, or factors related to the postoperative intensive care unit (ICU) environment. The role of inflammation, which has been described in the ICU setting, could also be a crucial determinant. In this review, we will discuss the neurological complications associated with LT, the neurocognitive complications after LT, and how to assess the LT-related neurological or neurocognitive complications. Furthermore, we will review the various hypotheses surrounding post-LT neurocognitive impairment and will conclude with recommendations for future directions.

Abstract
Improvement in cognitive function after orthotopic liver transplantation (LT) has been demonstrated in the acute setting immediately after LT and in acute liver failure. However, the longterm changes in cerebral hemodynamics after LT remain unexplored. Therefore, we aimed to evaluate the longterm changes in cerebral hemodynamics of patients with cirrhosis after LT. In this prospective cohort study, we performed transcranial Doppler ultrasonography (TCD) measuring the pulsatility index (PI), resistance index (RI), and breath-holding index (BHI) to evaluate cerebrovascular structural integrity and reactivity, respectively, in both middle cerebral arteries before and after LT. Neuropsychometric tests and West-Haven criteria were used for hepatic encephalopathy (HE) characterization. Interleukin 6 and tumor necrosis factor α plasma levels were measured. Descriptive statistics and Wilcoxon's test were used. There were 27 patients who were included. Median follow-up after LT was 6 months, mean age before LT was 46.3 ± 10.3 years, the main etiology was hepatitis C virus (59%), and most of the patients were Child-Pugh B (15/27). Model for End-Stage Liver Disease (MELD) score was 16 ± 7.5, MELD-Na was 19.3 ± 7.1, Psychometric Hepatic Encephalopathy Score was -3.48 ± 3.66, and critical flicker fusion (CFF) was 40.28 ± 5.70 Hz. Before LT, 17/27 patients had HE and 11/27 ascites. A decrease of 20.8% and 13.5% in PI and RI was observed after LT (P < 0.001, both), together with an increase in BHI (32.4%, P = 0.122). These changes in cerebral hemodynamics paralleled those in systemic inflammation. Clinical improvement in cognition was observed in all patients with overt HE after LT. In conclusion, these results show a significant improvement in cerebral hemodynamics after LT, obtained through TCD, indicating less arterial cerebral vasoconstriction together with a decrease in systemic inflammation. Changes in cerebral vasoconstriction can be the basis for the improvement in cognitive function after LT in the long term.

Abstract
Background Central nervous system complications after transplantation occur in up to 40% of recipients and these complications are associated with increased length of hospital stay and mortality. Catatonia is a neuropsychiatric clinical syndrome which has been described in case reports and in a small case series as occurring in the immediate post-solid organ transplantation (SOT) period, and it has been attributed to calcineurin inhibitor neurotoxicity, psychological vulnerability, and depression. Among transplant recipients, the incidence of catatonia is unknown; it may be under diagnosed in part due to a broad differential diagnosis in the post-transplantation setting, which includes hypoactive delirium, non-convulsive status epilepticus, drug toxicity, conversion disorder, and volitional uncooperativeness. Case Report We present 2 cases of catatonia diagnosed in liver allograft recipients. We also reviewed current literature for cases of catatonia among SOT recipients. We provide provisional evaluation and management strategies of recipients with clinical concern for catatonia. Conclusions Despite difficulties in establishing the diagnosis, catatonia after liver transplantation was rapidly responsive to intravenous lorazepam, indicating that changing immunosuppressants may be avoidable.

Abstract
Controversy exists whether NE after LT are more frequently observed in children or adults. We aimed to compare the incidence and outcomes for NE after LT in pediatric and adult recipients. A single-center cohort study, including all LT between 2001 and 2013, was performed. Definition of NE included impaired consciousness, delirium, seizures, focal neurologic deficit, visual impairment, or slurred speech. A cohort of 443 consecutive LT recipients was included: 307 adults and 136 children. Cumulative incidence of NE was similar between adults 15% (n = 41) and children 16% (n = 20; P = .73) with a complete neurological recovery in 62% and 95% of the patients, respectively (P < .0001). Adults with NE had significantly lower survival (70% vs 76%; P = .015) with a HR of 2.36; this was similarly observed in children (45% vs 66%; HR 2.05, CI 0.66; 6.34). Independent risk factors for NE in adults were pre-LT ascites, delta sodium, and post-LT hypomagnesemia, whereas in children pre-LT encephalopathy ≥II and serum albumin were associated with NE. Although a similar incidence of NE after LT was observed, children were more likely to achieve neurological recovery. Risk factors for the development of NE are difficult to assess in both populations.

Longterm calcineurin inhibitor therapy and brain function in patients after liver transplantation. Liver Transpl 2018; 24:56-66.

Abstract
Calcineurin inhibitors (CNIs) frequently induce neurological complications early after orthotopic liver transplantation (OLT). We hypothesize that longterm CNI therapy after OLT causes dose-dependent cognitive dysfunction and alteration of brain structure. In this study, 85 OLT patients (20 with CNI-free, 35 with CNI low-dose, and 30 with standard-dose CNI immunosuppression) underwent psychometric testing and cerebral magnetic resonance imaging approximately 10 years after OLT to assess brain function and structural brain alterations. A total of 33 healthy patients adjusted for age, sex, and education served as controls. Patients receiving CNI showed a significantly worse visuospatial/constructional ability compared with controls (P ≤ 0.04). Furthermore, patients on low-dose CNI therapy had an overall impaired cognitive function compared with controls (P = 0.01). The tacrolimus total dose and mean trough level were negatively correlated to cognitive function. CNI doses had been adjusted in 91% of the patients in the low-dose and CNI-free groups in the past due to CNI-induced kidney damage. Patients treated with CNI showed significantly more white matter hyperintensities (WMH) than patients on CNI-free immunosuppression and controls (P < 0.05). Both the mean cyclosporine A and tacrolimus trough levels correlated significantly with WMH. In conclusion, longterm CNI therapy carries a risk of cognitive dysfunction especially in patients who already showed nephrotoxic side effects indicating an increased susceptibility of these patients against toxic CNI effects. This subgroup of patients might benefit from a change to CNI-free immunosuppression. Liver Transplantation 24 56-66 2018 AASLD.

Abstract
The postoperative management of patients immediately after liver transplantation requires knowledge of this complex surgery and the physiology that accompanies liver failure. A multidisciplinary approach to the care of these patients is essential in order to reduce postoperative complications and preserve function in the transplanted organ. By their nature, patients undergoing liver transplantation have complicated medical problems before surgery which must be borne in mind when managing them after surgery. Haemorrhage, haemodynamic instability, acute renal failure, hepatic artery thrombosis and primary graft non-function are some of the complications that clinicians must be prepared for in the first days after transplantation. Pre-empting complications and acting rapidly to overt them is likely to have a considerable positive impact in these patients.

Hepatic encephalopathy before and neurological complications after liver transplantation have no impact on the employment status 1 year after transplantation. World J Hepatol 2017; 9:519-532.

Abstract
AIM To investigate the impact of hepatic encephalopathy before orthotopic liver transplantation (OLT) and neurological complications after OLT on employment after OLT. METHODS One hundred and fourteen patients with chronic liver disease aged 18-60 years underwent neurological examination to identify neurological complications, neuropsychological tests comprising the PSE-Syndrome-Test yielding the psychometric hepatic encephalopathy score, the critical flicker frequency and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), completed a questionnaire concerning their occupation and filled in the short form 36 (SF-36) to assess health-related quality of life before OLT and 12 mo after OLT, if possible. Sixty-eight (59.6%) patients were recruited before OLT, while on the waiting list for OLT at Hannover Medical School [age: 48.7 ± 10.2 years, 45 (66.2%) male], and 46 (40.4%) patients were included directly after OLT. RESULTS Before OLT 43.0% of the patients were employed. The patients not employed before OLT were more often non-academics (employed: Academic/non-academic 16 (34.0%)/31 vs not employed 10 (17.6%)/52, P = 0.04), had more frequently a history of hepatic encephalopathy (HE) (yes/no; employed 15 (30.6%)/34 vs not employed 32 (49.2%)/33, P = 0.05) and achieved worse results in psychometric tests (RBANS sum score mean ± SD employed 472.1 ± 44.5 vs not employed 443.1 ± 56.7, P = 0.04) than those employed. Ten patients (18.2%), who were not employed before OLT, resumed work afterwards. The patients employed after OLT were younger [age median (range, min-max) employed 47 (42, 18-60) vs not employed 50 (31, 29-60), P = 0.01], achieved better results in the psychometric tests (RBANS sum score mean ± SD employed 490.7 ± 48.2 vs not employed 461.0 ± 54.5, P = 0.02) and had a higher health-related quality of life (SF 36 sum score mean ± SD employed 627.0 ± 138.1 vs not employed 433.7 ± 160.8; P < 0.001) compared to patients not employed after OLT. Employment before OLT (P < 0.001), age (P < 0.01) and SF-36 sum score 12 mo after OLT (P < 0.01) but not HE before OLT or neurological complications after OLT were independent predictors of the employment status after OLT. CONCLUSION HE before and neurological complications after OLT have no impact on the employment status 12 mo after OLT. Instead younger age and employment before OLT predict employment one year after OLT.

Abstract
The brain operates in an extraordinarily intricate environment which demands precise regulation of electrolytes. Tight control over their concentrations and gradients across cellular compartments is essential and when these relationships are disturbed neurologic manifestations may develop. Perturbations of sodium are the electrolyte disturbances that most often lead to neurologic manifestations. Alterations in extracellular fluid sodium concentrations produce water shifts that lead to brain swelling or shrinkage. If marked or rapid they can result in profound changes in brain function which are proportional to the degree of cerebral edema or contraction. Adaptive mechanisms quickly respond to changes in cell size by either increasing or decreasing intracellular osmoles in order to restore size to normal. Unless cerebral edema has been severe or prolonged, correction of sodium disturbances usually restores function to normal. If the rate of correction is too rapid or overcorrection occurs, however, new neurologic manifestations may appear as a result of osmotic demyelination syndrome. Disturbances of magnesium, phosphate and calcium all may contribute to alterations in sensorium. Hypomagnesemia and hypocalcemia can lead to weakness, muscle spasms, and tetany; the weakness from hypophosphatemia and hypomagnesemia can impair respiratory function. Seizures can be seen in cases with very low concentrations of sodium, magnesium, calcium, and phosphate.

Abstract
Major neurologic morbidity, such as seizures and encephalopathy, complicates 20-30% of organ and stem cell transplantation procedures. The majority of these disorders occur in the early posttransplant period, but recipients remain at risk for opportunistic infections and other nervous system disorders for many years. These long-term risks may be increasing as acute survival increases, and a greater number of "sicker" patients are exposed to long-term immunosuppression. Drug neurotoxicity accounts for a significant proportion of complications, with posterior reversible leukoencephalopathy syndrome, primarily associated with calcineurin inhibitors (i.e., cyclosporine and tacrolimus), being prominent as a cause of seizures and neurologic deficits. A thorough evaluation of any patient who develops neurologic symptoms after transplantation is mandatory, since reversible and treatable conditions could be found, and important prognostic information can be obtained.
