Abstract
Medical and surgical advancements have improved survival in children with acquired and congenital heart disease (CHD), but the burden of neurological morbidity is high. Brain disorders associated with CHD include white matter injury, stroke, seizure, and neurodevelopmental delays. While genetics and disease-specific factors play a substantial role in early brain injury, therapeutic management of the heart disease intensifies the risk. There is a growing interest in understanding how to reduce brain injury and improve neurodevelopmental outcomes in cardiac diseases. Pediatric neurologists serve a vital role in care teams managing these complex patients, providing interpretation of neuromonitoring and imaging, managing neurologic emergencies, assisting with neuro prognostication, and identifying future research aims.

Risk of Cerebral Aneurysm Rupture After Liver Transplantation: Development and Validation of a Hemorrhagic Stroke Scoring Model. J Korean Med Sci 2024; 39:e88. [PMID: 38469964 PMCID: PMC10927392 DOI: 10.3346/jkms.2024.39.e88] [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: 11/09/2023] [Accepted: 01/15/2024] [Indexed: 03/13/2024] Open
Abstract
BACKGROUND Liver transplantation (LT) patients appear to be more prone to neurological events compared to individuals undergoing other types of solid-organ transplantation. The aims of the present study were to analyze the prevalence of unruptured intracranial aneurysms (UIAs) in patients undergoing liver transplantation (LT) and to examine the perioperative occurrence of subarachnoid hemorrhage (SAH). Also, it intended to systematically identify the risk factors of SAH and hemorrhagic stroke (HS) within a year after LT and to develop a scoring system which involves distinct clinical features of LT patients. METHODS Patients who underwent LT from January 2012 to March 2022 were analyzed. All included patients underwent neurovascular imaging within 6 months before LT. We conducted an analysis of prevalence and radiological features of UIA and SAH. The clinical factors that may have an impact on HS within one year of LT were also reviewed. RESULTS Total of 3,487 patients were enrolled in our study after applying inclusion and exclusion criteria. The prevalence of UIA was 5.4%. The incidence of SAH and HS within one year following LT was 0.5% and 1.6%, respectively. We developed a scoring system based on multivariable analysis to predict the HS within 1-year after LT. The variables were a poor admission mental status, the diagnosis of UIA, serum ammonia levels, and Model for End-stage Liver Disease (MELD) scores. Our model showed good discrimination among the development (C index, 0.727; 95% confidence interval [CI], 0.635-0.820) and validation (C index, 0.719; 95% CI, 0.598-0.801) cohorts. CONCLUSION The incidence of UIA and SAH was very low in LT patients. A poor admission mental status, diagnosis of UIA, serum ammonia levels, and MELD scores were significantly associated with the risk of HS within one year after LT. Our scoring system showed a good discrimination to predict the HS in LT patients.

Abstract
BACKGROUND Tacrolimus is the most common immunosuppressant used after transplant, yet it can result in moderate-to-severe neurotoxicity in up to 32% of patients. Signs of neurotoxicity can vary from mild (tremor or headache) to severe (posterior reversible encephalopathy syndrome or psychosis. Prompt recognition and management is needed to lead to symptom resolution. OBJECTIVE The objective of this study is to describe the clinical presentation of tacrolimus-induced psychosis, a type of tacrolimus-inducted neurotoxicity, and distinguish it from other central nervous system disturbances, including delirium. METHODS AND RESULTS We present a case of delayed onset tacrolimus-induced psychosis with focus on unique clinical features and management strategies. We conducted a systematic review of cases of tacrolimus-induced psychosis using the PubMed database and included 15 manuscripts in our review. CONCLUSIONS Tacrolimus-induced psychosis is a unique presentation of tacrolimus-related neurotoxicity and can present without the cardinal symptoms of delirium. The data on isolated psychotic symptoms are limited with current literature focusing on more common presentations of tacrolimus-induced neurotoxicity, such as delirium and tremor. Development of psychosis can occur later in the treatment course and at normal tacrolimus serum levels. It can improve with antipsychotic therapies, but primary management should include cross-titration to an alternate immunosuppressant regimen.

Abstract
OBJECTIVE Patients with posterior reversible encephalopathy syndrome (PRES) can develop seizures during the acute phase. We sought to determine the long-term risk of seizure after PRES. METHODS We performed a retrospective cohort study using statewide all-payer claims data from 2016-2018 from nonfederal hospitals in 11 US states. Adults admitted with PRES were compared to adults admitted with stroke, an acute cerebrovascular disorder associated with long-term risk of seizure. The primary outcome was seizure diagnosed during an emergency room visit or hospital admission after the index hospitalization. The secondary outcome was status epilepticus. Diagnoses were determined using previously validated ICD-10-CM codes. Patients with seizure diagnoses before or during the index admission were excluded. We used Cox regression to evaluate the association of PRES with seizure, adjusting for demographics and potential confounders. RESULTS We identified 2095 patients hospitalized with PRES and 341,809 with stroke. Median follow-up was 0.9 years (IQR, 0.3-1.7) in the PRES group and 1.0 years (IQR, 0.4-1.8) in the stroke group. Crude seizure incidence per 100 person-years was 9.5 after PRES and 2.5 after stroke. After adjustment for demographics and comorbidities, patients with PRES had a higher risk of seizure than patients with stroke (HR, 2.9; 95% CI, 2.6-3.4). Results were unchanged in a sensitivity analysis that applied a two-week washout period to mitigate detection bias. A similar relationship was observed for the secondary outcome of status epilepticus. INTERPRETATION PRES was associated with an increased long-term risk of subsequent acute care utilization for seizure compared to stroke.

Trends and Outcomes of Left Atrial Appendage Occlusion in Renal and Liver Transplant Recipients: Insights From the United States National Inpatient and Readmission Database. Curr Probl Cardiol 2023; 48:101488.

Abstract
Left atrial appendage occlusion using the Watchman device has emerged as an alternative treatment strategy for preventing strokes in patients with atrial fibrillation. However, there is no data on its safety and clinical outcomes in prior renal or liver transplant recipients. We included a total of 61,995 patients from the National Inpatient Sample (NIS, in-hospital outcomes) and 55,048 patients from the National Readmission Database (NRD, 30-day outcomes) who underwent percutaneous left atrial appendage occlusion (LAAO). From this group, 0.65% (n=405) and 0.62% (n=339) were renal and liver transplant recipients in NIS and NRD respectively. Transplant recipients were younger compared with non-transplant recipients (mean age 69 vs 77 years, P=<0.01). There was little difference in terms of in-hospital mortality (0% vs 0.2%, P=0.43), major complications (6.2% vs 5.6%, P=0.61), cardiovascular complications (2.5% vs 2.8%, P=0.73), neurological complications (1.2% vs 0.7%, P=0.21) or bleeding complications (1.2% vs 0.7%, P=0.99) between transplant vs. non-transplant patients. Based on the NRD database, 30-day readmission rate was not meaningfully different for transplant recipients undergoing LAAO (9.44%) when compared to non-transplant patients (8.12%, [log-rank, P=0.56]). There was no difference between 30-day major or cardiovascular complications, however vascular complication rates were significantly higher for transplant recipients (OR 2.56, 95% CI [(1.66-3.47]). Our study findings suggest that LAAO may be safe for patients with a prior renal or liver transplant in terms of major complications, cardiovascular complications, and all-cause readmission rates. However vascular complications may be higher in transplant recipients. Further large-scale studies are needed to confirm these findings.

Intraoperative Optic Nerve Sheath Diameter as a Predictor of Early Tacrolimus Neurotoxicity after Living Donor Liver Transplantation. Anaesth Crit Care Pain Med 2023; 42:101178.

Abstract
BACKGROUND During liver transplantation, graft reperfusion triggers cerebral hyperemia, increases intracranial pressure, and disrupts the blood-brain barrier, thereby increasing the risk for immunosuppression neurotoxicity. Therefore, we tested the intraoperative optic nerve sheath diameter (ONSD) for predicting tacrolimus neurotoxicity after liver transplantation. BASIC PROCEDURES We prospectively included 100 adult patients who underwent living donor liver transplantation. The ultrasonographic ONSD 5 min after reperfusion was used as the index test, whereas the occurrence of early tacrolimus neurotoxicity was used as the reference. The area under the receiver operating characteristic curve (AUROC) was used to estimate the ONSD prediction accuracy. We reported the specificity and sensitivity of ONSD 5 and 30 min after reperfusion. Cutoffs were derived from the ROC curves. In addition, we used regression to control for confounders while testing the association between the ONSD and tacrolimus neurotoxicity. MAIN FINDINGS The AUROC at T3 was 0.74 (95% confidence interval (CI), 0.63-0.85, P < 0.001). An ONSD of ≥6.4 mm at T3 had an 86% sensitivity (95% CI, 68%-96%) and 53% specificity (95% CI, 41%-65%). An ONSD of ≥6.4 mm at T3 had an adjusted odds ratio for tacrolimus neurotoxicity of 6.3 (95% CI, 1.9-21, P = 0.003). CONCLUSIONS This data indicates that intraoperative ultrasonic ONSD after reperfusion can predict tacrolimus neurotoxicity after liver transplantation.

Transient central hypoxemia due to intermittent high-degree atrioventricular block in a heart-transplanted patient diagnosed during routine electroencephalography: a case report. J Med Case Rep 2023; 17:3.

Abstract
BACKGROUND Bradycardia frequently occurs in heart-transplanted patients, mainly as a temporally restricted manifestation early after transplantation and often without symptoms. A high-degree atrioventricular block is mostly symptomatic through cerebral hypoxia induced through cerebral hypoperfusion. Only a few published cases show this specific electroencephalography result in this context. The purpose of this case is to bring attention to atypical manifestations of typical cardiac complications after heart transplantation and the importance of perseverance in the diagnostic. CASE PRESENTATION A Central European man in his 50s with history of heart transplantation 31 years previously was admitted to the internal medicine ward for short-lived recurrent episodes of generalized weakness with multiple falls but without loss of consciousness. During routine electroencephalography, the patient perceived this recurrent sensation. This episode coincided with a transient third-degree atrioventricular block followed 8-10 seconds later by a generalized slowing of the electroencephalography, reflecting cerebral hypoxia due to cerebral hypoperfusion. Holter monitoring confirmed the diagnosis. A pacemaker was implanted, consequently resolving the episodes. CONCLUSION This case report illustrates the pathophysiological central hypoxemic origin of episodes of generalized weakness caused by a high-degree atrioventricular block in a patient surviving 29 years after heart transplant. It highlights the benefit of electroencephalography as a diagnostic tool in well-selected patients.

Abstract
Metabolomics enables the analysis of metabolites within an organism, which offers the closest direct measurement of the physiological activity of the organism, and has advanced efforts to characterize metabolic states, identify biomarkers, and investigate metabolic pathways. A high degree of innovation in analytical techniques has promoted the application of metabolomics, especially in the study of clinical surgery. Metabolomics can be employed as a clinical testing method to maximize therapeutic outcomes, and has been applied in rapid diagnosis of diseases, timely postoperative monitoring, prognostic assessment, and personalized medicine. This review focuses on the use of mass spectrometry and nuclear magnetic resonance-based metabolomics in clinical surgery, including identifying metabolic changes before and after surgery, finding disease-associated biomarkers, and exploring the potential of personalized therapy. Challenges and opportunities of metabolomics in organ transplantation are also discussed, with a particular emphasis on metabolomics in donor organ evaluation and protection, prognostic outcome prediction, as well as postoperative adverse reaction monitoring. In the end, current limitations of metabolomics in clinical surgery and future research directions are presented.

Abstract
INTRODUCTION Posterior reversible encephalopathy syndrome is a rare neurologic complication that can occur under immunosuppressive therapy with CNI after organ transplantation. METHODS We retrospectively reviewed medical records of 545 patients who underwent lung transplantation between 2012 and 2019. Within this group, we identified 30 patients with neurological symptoms typical of PRES and compared the characteristics of patients who were diagnosed with PRES (n = 11) to those who were not (n = 19). RESULTS The incidence of PRES after lung transplantation was 2%. Notably, 73% of the patients with PRES were female and the mean age was 39.2. Seizure (82% vs. 21%, p = .002) was the most common neurological presentation. The risk of developing PRES was significantly associated with age (OR = .92, p < .0001) and having cystic fibrosis (CF) (OP = 10.1, p < .0001). Creatinine level (1.9 vs. 1.1 mg/dl, p = .047) and tacrolimus trough level (19.4 vs. 16.5 ng/ml, p = .048) within 1 week prior to neurological symptoms were significantly higher in patients with PRES. CONCLUSION Renal insufficiency and high tacrolimus levels are associated with PRES. A change of immunosuppressive drug should be done after confirmed PRES diagnosis or immediately in case of severe neurological dysfunction to improve neurological outcomes and minimize the risk of early allograft rejection.

The Prevalence of Neurological Complication after Renal Transplantation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8763304. [PMID: 35832523 PMCID: PMC9273377 DOI: 10.1155/2022/8763304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 04/15/2022] [Accepted: 04/18/2022] [Indexed: 11/17/2022]
Abstract
Objective To evaluate the incidence of neurological complications (NCs) after renal transplantation by meta-analysis. Methods A broad literature search in PubMed, Embase, and Cochrane-Library was performed from inception to December 31, 2021, to collect published studies on the incidence of NCs after kidney transplantation. The R language meta-package was used to organize and analyze the data. Results 17 articles including 1,1119 participants were considered eligible. There were 3 studies that recorded unclassified NCs (249 participants), 6 that recorded nervous system CMV infection (1489 participants), 3 that recorded headache (243 participants), and 5 that recorded cerebrovascular events (9138 participants). There was significant heterogeneity (all I 2 ≥ 75%) in all analyses, and random-effects models were selected. Meta-analysis results showed that the incidence of unclassified NCs was 0.29 (95% CI (0.16-0.48)), the incidence of nervous system CMV infection was 0.38 (95% CI (0.26-0.52)), the incidence of headache was 0.55 (95% CI (0.44-0.66)), and the incidence of stroke was 0.05 (95% CI (0.02-0.09)). Egger's test showed that there was no conspicuous publication bias in the included literature in each group. Conclusions Headache had the highest incidence (55%) in the nervous system after KT, followed by nervous system CMV infection (38%) and stroke (5%). Nevertheless, due to the inconsistencies in the types of NCs included and the follow-up time, our results might only serve as an epidemiological reference for the specific incidence differences.

Abstract
OBJECTIVES To describe the epidemiology and clinical presentation of central nervous system (CNS) infections in solid organ transplant (SOT) recipients in the current era of transplantation. METHODS Patients from the Swiss Transplant Cohort Study (STCS) transplanted between 2008 and 2018 were included with a median follow-up of 3.8 years. Epidemiological, microbiological, and clinical data were extracted from the STCS database and patients' medical records. We calculated incidence rates and 90-day survival of transplant recipients with CNS infection. RESULTS Among 4762 patients, 42 episodes of CNS infection in 41 (0.8%) SOT recipients were identified, with an overall incidence rate of 2.06 per 1000 patient-years. Incidence of CNS infections was similar across all types of transplantations. Time to CNS infection onset ranged from 0.6 to 97 months after transplant. There were 22/42 (52.4%) cases of viral infections, 11/42 (26.2%) of fungal infections, 5/42 (11.9%) of bacterial infections and 4/42 (9.5%) of probable viral/bacterial etiology. Clinical presentation was meningitis/encephalitis in 25 cases (59.5%) and brain-space occupying lesions in 17 cases (40.5%). Twenty-three cases (60.5%) were considered opportunistic infections. Diagnosis were achieved mainly by brain biopsy/necropsy (15/42, 36%) or by cerebrospinal fluid analysis (20/42, 48%). Up to 40% of cases (17/42) had concurrent extra-neurological disease localizations. Overall, 90-day mortality rate was 29.0% (73.0% for fungal, 14.0% for viral and 11.0% for bacterial and probable infections, p<0.0001). CONCLUSIONS CNS infections were rare in the STCS, with viral meningoencephalitis being the most common disease. Fungal infections were associated with a high mortality.

Abstract
This systematic review presents clinical evidence on early and long-term cerebral diseases in liver transplant recipients. The literature search led to the retrieval of 12 relevant studies. Early postoperative cerebral complications include intracranial hemorrhage associated with a coexisting coagulopathy, perioperative hypertension, and higher MELD scores and is more frequent in critically ill recipients; central pontine and extrapontine myelinolysis are associated with notable perioperative changes in the plasma Na+ concentration and massive transfusion. Long-term follow-up cerebral complications include focal brain lesions, cerebrovascular diseases, and posterior reversible encephalopathy; there is no proven relationship between the toxicity immunosuppressive drugs and cerebral complications. This SR confirms a very low incidence of opportunistic cerebral infections.

Abstract
Calcineurin inhibitors (CNIs) have been the foundation of immunosuppression in solid organ transplantation since the 1980s. Cyclosporine A (CSA), the first in class, was identified as the metabolite of the soil fungus Tolypocladium inflatum Gams as part of a larger program of screening for naturally occurring fungal metabolites with biologic activity in the 1970s. Significant immunosuppressive effects were discovered and consequently CSA was trialed as an immunosuppressant in renal transplantation. This initial success led to its widespread study and adoption in solid organ transplantation. This novel agent yielded significant improvements in both 1 year and longer-term allograft and patient survival. Subsequently, a similar and more potent CNI, tacrolimus was developed. Today, it is the principal CNI used for prevention of allograft rejection. Like all other immunosuppressives, the benefits of CNIs are counterbalanced by side effects and complications resulting from drug toxicity. This chapter comprehensively reviews the clinical use of CNIs in cardiac transplantation.

Abstract
Background Lung transplantation (LT) requires complex multidisciplinary organization and constitutes a therapeutic option and a life-saving procedure. Although the number of lung recipients continues to increase, neurological complications and death rates following lung transplantation are still higher than desirable. Purpose This study aims to analyse the neuroimaging findings in a cohort of adult patients with LT. Material and Methods A retrospective cohort study of all lung transplant recipients (344 patients: 205 men and 139 women) at a single institution from January 2011 to January 2020. The collected data included demographic features, clinical data and evaluation of the imaging findings. We also recorded the date of neurological complication(s) and the underlying disease motivating lung transplantation. Results We found an elevated rate of neuroimaging findings in patients following LT with 32.6% of positive studies. In our cohort, the average time after LT to a neurological complication was 4.9 months post-transplant. Encephalopathy, critical illness polyneuropathy and stroke, in that order, were the most frequent neurological complications. Structural abnormalities in brain imaging were more often detected using MRI than CT for indications of encephalopathy and seizures. Conclusions LT recipients constitute an especially vulnerable group that needs close surveillance, mainly during the early post-transplant period.

Abstract
Neurologic complications are common in immunocompromised patients, including those with advanced human immunodeficiency virus, transplant recipients, and patients on immunomodulatory medications. In addition to the standard differential diagnosis, specific pathogens and other conditions unique to the immunocompromised state should be considered in the evaluation of neurologic complaints in this patient population. A thorough understanding of these considerations is critical to the inpatient neurologist in contemporary practice, as increasing numbers of patients are exposed to immunomodulatory therapies. In this review, we provide a chief complaint-based approach to the clinical presentations and diagnosis of both infectious and noninfectious complications particular to immunocompromised patients.

Abstract
As the risk of graft loss due to acute rejection has declined, the goal of post-transplant management has switched to long-term preservation of organ function. Minimizing calcineurin inhibitor (CNI)-related nephrotoxicity is a key component of this objective. Everolimus is a mammalian target of rapamycin inhibitor/proliferation-signal inhibitor with potent immunosuppressive and anti-proliferative effects. It has been widely investigated in large randomized clinical studies that have shown it to have similar anti-rejection efficacy compared with standard-of-care regimens across organ transplant indications. With demonstrated potential to facilitate the reduction of CNI therapy and preserve renal function, everolimus is an alternative to the current standard-of-care CNI-based regimens used in de novo and maintenance solid organ transplantation recipients. Here, we provide an overview of the evidence from the everolimus clinical study program across kidney, liver, heart, and lung transplants, as well as other key data associated with its use in CNI reduction strategies in adult transplant recipients.

Abstract
PURPOSE OF REVIEW Both broadly immunosuppressive medications and selective immunomodulatory agents that act on particular components of the immune system are increasingly used in the treatment of neurologic and non-neurologic diseases. These therapies predispose patients to particular infections, some of which may affect the nervous system. Therefore, familiarity with the clinical and radiologic features of neurologic infections associated with specific immunomodulatory therapies is of importance for the practicing neurologist. This article reviews these neuroinfectious conditions, as well as other neurologic complications unique to transplant recipients and other patients who are immunocompromised. RECENT FINDINGS Diagnosis of infectious pathogens in patients who are immunocompromised may be particularly challenging because a decreased immune response can lead to atypical imaging or laboratory findings. Next-generation sequencing and other novel diagnostic modalities may improve the rate of early identification of neurologic infections in patients who are immunocompromised and ultimately ameliorate outcomes in this vulnerable population. SUMMARY A broad range of bacterial, viral, fungal, and parasitic infections of the nervous system can complicate solid organ and hematopoietic cell transplantation as well as other forms of immunocompromise. In addition to neurologic infections, such patients are at risk of neurotoxic and neuroinflammatory complications related to immunomodulatory and immunosuppressive therapies. Early recognition of infectious and noninfectious complications of immunocompromise is essential to guide appropriate treatment, which can include antimicrobial therapy and, in some cases, withdrawal of the predisposing medication with a transition to an alternative regimen.

Abstract
OBJECTIVES Neurologic complications are more common in liver transplants than in other solid-organ transplants. One such neurologic complication, peripheral neuropathy, may cause functional limitations for recipients and have a negative effect on posttransplant quality of life. We aimed to examine the risk factors associated with the occurrence of clinical neuropathy after liver transplant and to investigate the frequency of sensory deficits. MATERIALS AND METHODS In this case-control study, we analyzed factors from medical records of 63 recipients who underwent living donor liver transplant during the period from January 2010 to December 2016. A neuropathy symptom score was assigned to identify the patients who had clinical neuropathy (case group) and the patients without clinical neuropathy (control group). Quantitative sensory testing was performed to measure the warm and cold detection thresholds, and the difference between the 2 groups was examined. RESULTS Compared with controls, patients with clinical neuropathy were older (61.0 vs 55.4 years; P = .028), had higher rates of diabetes (46.2% vs 16.0%; P = .03), and were taking antiviral agents against hepatitis B (100% vs 62%; P = .006). Patients with neuropathic symptoms had significantly increased frequencies of impairment of warm and cold detection thresholds. In addition, the greater severity of symptoms showed higher detection thresholds of warm (control, 40.7℃; mild-to-moderate, 43.8 ℃; severe, 46.0 ℃; P = .007) and cold (control, 28.8℃ ; mild-to-moderate, 27.0 ℃; severe, 21.8 ℃ ; P = .008). CONCLUSIONS Our findings show that older age, diabetes, and treatment with oral antiviral agents against hepatitis B virus were more likely to be associated with the occurrence of clinical neuropathy after liver transplant. Early awareness and careful monitoring are warranted.

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
A large number of neurological disorders can affect renal transplant recipients, potentially leading to disabling or life-threatening complications. Prevention, early diagnosis and appropriate management of these conditions are critical to avoid irreversible lesions. A pivotal role in the pathogenesis of common post-transplant neurological disorders is played by immunosuppressive therapy. The most frequently administered regimen consists of triple immunosuppression, which comprises a calcineurin inhibitor (CNI), a purine synthesis inhibitor and glucocorticoids. Some of these immunosuppressive drugs may lead to neurological signs and symptoms through direct neurotoxic effects, and all of them may be responsible for the development of tumors or opportunistic infections. In this review, after a brief summary of neurotoxic pathogenetic mechanisms encompassing recent advances in the field, we focus on the clinical presentation of more common and severe immunosuppression-related neurological complications, classifying them by characteristics of urgency and anatomic site. Our goal is to provide a general framework that addresses such clinical issues with a multidisciplinary approach, as these conditions require.

Abstract
The calcineurin inhibitors cyclosporine and tacrolimus are used for their immunosuppressive effects. Neurotoxic side effects include tremor, paresthesia, and headache. Rarer neurotoxicities include seizure, posterior reversible encephalopathy syndrome, and encephalopathy. Tacrolimus tends to be more neurotoxic than cyclosporine. Management of toxicities associated with calcineurin inhibitors includes dose reduction, switching between calcineurin inhibitors, or switching to a calcineurin-free regimen. Tumor necrosis factor (TNF) inhibitors are used in autoimmune diseases. Management of demyelinating conditions among patients treated with anti-TNF should follow standard of care and withdrawal of the anti-TNF. This drug class should be avoided in patients with a history of demyelinating conditions.

Abstract
BACKGROUND/AIMS Sleep disorders (SDs) are frequently seen in patients with liver cirrhosis. Polysomnography (PSG), actigraphy, and electroencephalogram (EEG) are the common objective methods to diagnose SDs. The most commonly used subjective methods are the Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale (ESS). We aimed to evaluate the effect of liver transplantation (LTx) on SDs using a combination of objective (PSG and EEG) and subjective (PSQI and ESS) methods. MATERIALS AND METHODS A total of 18 patients with cirrhosis on an LTx waiting list were included in this study. Patient clinical status and biochemical parameters were evaluated. All patients completed the validated Turkish forms of the PSQI and ESS before and 9 months after LTx. All patients underwent EEG and PSG before and 9 months after LTx. RESULTS In total, 18 patients with liver cirrhosis (men: 12; 66.7%, mean age: 53.22±10.43 years) were included in this study. Pretransplant mean PSQI and ESS scores were 8.4±3.11 and 7.28±3.89, respectively; 9-month posttransplant mean PSQI and ESS scores were 4.5±2.8 and 4.72±2.91 (p<0.01), respectively. Before transplantation, metabolic encephalopathy was detected in 6 patients by EEG, whereas metabolic encephalopathy was detected in only 1 patient posttransplant. Posttransplantation PSG sleep duration (all stages) increased relative to pretransplant PSG values. Sleep latency and rapid eye movement latency were found to be reduced compared to the pretransplant values. CONCLUSION This pilot study compared SDs in patients with pre- and post-LTx by combining the subjective and objective methods. Significant SD improvements were found at the 9th month.

Abstract
Kidney transplantation is the preferred treatment modality in patients with ESKD. However, there are associated complications that arise from immunosuppressive medications, infections, and associated comorbidities. Neurologic disorders frequently develop in patients who have received a kidney transplant, which in turn increases the associated morbidity and mortality. This review discusses the common neurologic disorders after kidney transplantation, including infections, cognitive decline, drug-related conditions, malignancy, seizure, and other neurologic complications.

Abstract
Intracranial peripherally enhancing lesions in immunosuppressed solid organ transplant recipients represent a unique diagnostic and management dilemma due to the vast array of differentials that demand consideration. Diagnosis of the underlying pathology is often guided by the use of magnetic resonance imaging (MRI). We present the first published case series of three cardiac transplant recipients with significantly atypical neuroradiological findings contrary to the tenets of contemporary literature. Our rare case series consists of: (1) A sterile Mycobacterium pyogenic abscess mimicking glioblastoma multiforme due to an immunosuppressed state (2) Epstein Barr Virus encephalitis masquerading as Central Nervous System Post-Transplant Lymphoproliferative Disorder (3) An unusual case of partially treated disseminated Nocardiosis warning of the need to consider the immunosuppressed state and partial treatment response obfuscating classical MRI appearances. We utilise these unprecedented cases as the basis of a literature review to understand the pathophysiology behind the peculiar imaging findings in this rarefied cohort of transplant recipients, and rationalise why the MRI findings in each instance contradicts the accepted imaging patterns. In the setting of potential unreliability of neuroradiology in this immunosuppressed unique subgroup, we hope to impart to clinicians that definitive diagnosis obtained by emergent neurosurgical intervention may be necessary to accurately and expediently guide further medical management.

Abstract
Neurological complications are common after liver transplantation, as they affect up to one-third of the transplanted patients and are associated with significant morbidity. The introduction of calcineurin inhibitors, cyclosporine A and tacrolimus, in immunosuppressive regimens significantly improved the outcome of solid-organ transplantation even though immunosuppression-associated neurotoxicity remains a significant complication, particularly occurring in about 25% of cases after liver transplantation. The immunosuppressant cyclosporine A and tacrolimus have been associated with the occurrence of major neurological complications, diffuse encephalopathy being the most common. The biochemical and pathogenetic basis of calcineurin inhibitors-induced neurotoxicity are still unclear although several mechanisms have been suggested. Early recognition of symptoms could help reduce neurotoxic event. The aim of the study was to evaluate cerebral changes through MRI, in particular with diffusion-weighted images (DWI) and apparent diffusion coefficient (ADC) maps, in two patients undergoing liver transplantation after immunosuppressive therapy. We describe two patients in which clinical pictures, presenting as a severe neurological condition, early after orthotopic liver transplantation during immunosuppression therapy, showed a different evolution in keeping with evidence of focal-multifocal lesions at DWI and ADC maps. At clinical onset, DWI showed hyperintensity of the temporo-parieto-occipital cortex with normal ADC values in the patient with following good clinical recovery and decreased values in the other one; in the latter case, MRI abnormalities were still present after ten days, until the patient's exitus. The changes in DWI with normal ADC may be linked to brain edema with a predominant vasogenic component and therefore reversible, while the reduction in ADC is due to cytotoxic edema and linked to more severe, nonreversible, clinical picture. Brain MRI and particularly DWI and ADC maps provide not only a good and early representation of neurological complications during immunosuppressant therapy but can also provide a useful prognostic tool on clinical outcome of the patient.

Abstract
INTRODUCTION The preoperative elevation of ammonia may be associated with postoperative neurologic complications. The aim of this study was to evaluate the effect of preoperative ammonia level on the incidence of delirium in patients after liver transplantation (LT). MATERIALS AND METHODS Patients (n = 260) who received LT from January 2010 to July 2017 in a single university hospital were retrospectively reviewed. The patients' demographic data, perioperative managements, and postoperative complications were assessed. Patients were divided into the following 2 groups: those who had a preoperative elevation (Group A, n = 158) and those with a normal range (Group C, n = 102). The cut-off value for a normal serum ammonia level in our hospital was defined as 32 μg/dL. RESULTS After propensity score matching, there was no difference in the incidence of delirium between the groups (P = .784). Delirium occurred in 8 of 68 (11.76%) patients in Group A and 7 of 68 (10.29%) patients in Group C after LT. In addition, there was no difference in the incidence of delirium between the groups, even patients were categorized based on serum ammonia levels into 3 groups as follows: < 32 μg/dL (28/158 [17.72%]), 32 to 65 μg/dL (28/158 [17.72%]), and >65 μg/dL (28/158 [17.72%]) (P = .134). CONCLUSIONS The preoperative serum ammonia level was not related with the incidence of postoperative delirium. The high elevation group, especially those with greater than 65 μg/dL of preoperative ammonia, was also not related with the incidence of delirium. However, our study is limited by its retrospective design, so future prospective studies are needed.

Abstract
Background Although kidney transplantation outcomes have improved dramatically after using calcineurin inhibitors (CNIs), CNI toxicity continues to be reported and the mechanism remains uncertain. Here, we investigated the neurotoxicity of CNIs by focusing on the viability of glioma cells. Methods Glioma cells were treated with several concentrations of CNIs for 24 hours at 37℃ and their cell viability was evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Results Exposure to 0, 0.25, 0.5, 2.5, 5.0, and 10.0 mM concentrations respectively showed 100%, 64.3%, 61.3%, 68.1%, 62.4%, and 68.6% cell viability for cyclosporine and 100%, 38.6%, 40.8%, 43.7%, 37.8%, and 43.0% for tacrolimus. The direct toxic effect of tacrolimus on glioma cell viability was stronger than that of cyclosporine at the same concentration. Conclusion CNIs can cause neurological side effects by directly exerting cytotoxic effects on brain cells. Therefore, we should carefully monitor the neurologic symptoms and level of CNIs in kidney transplant patients.

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
Background Serum sodium (Na) is considered to reflect the severity of liver cirrhosis. In the last few years, much effort has been made to integrate this association into prognostic models after liver transplantation. The aim of this study was to investigate the associations between peritransplant Na and neurological complications, as well as short-term survival, after liver transplantation. Material/Methods A total of 306 liver transplantations between 2012 and 2015 were evaluated. Pre- and posttransplant sodium concentrations were investigated with regard to 3-month survival and incidence of posttransplant neurological complications, along with other factors present in the operative side of the recipient and donor. Results The 3-month survival rate was 94%. Neither hyponatremia (<130 mEq/L) nor hypernatremia (>145 mEq/L) at pretransplantion predicted 3-month survival. A large amount of intraoperative blood transfusion and a large delta Na showed a significant association with poor outcomes at 3 months. On multivariate analysis, the requirement of blood transfusion and warm ischemia time remained independent prognostic factors for 3-month mortality. Hyponatremia and a large delta Na tended to lead to the frequent development of neurological complications. These complications, secondary to rapid Na correction, were concerning and potentially led to a prolonged hospital stay and early mortality. Conclusions Rapid change in the sodium level might be caused by large amounts of blood transfusion products. This leads to a diminished short-term survival, as well as a higher rate of neurological complications.

Abstract
The aim of this systematic review and meta-analysis was to evaluate the prevalence of neurological complication after renal transplantation. The searches were conducted by two independent researchers in the international (PubMed, Web of Science, Scopus, and Google Scholar) and national databases (Magiran and SID) to find the relevant studies published in English and Persian languages since the creation of the databases until January 2019 (without time limitations). The keywords used in the search strategy were: neurologic complication, central nervous system, peripheral nervous system, tremor, CVA, encephalopathy, neurological complications, renal transplantation, renal failure, kidney transplantation, immunosuppression, neurotoxicity, opportunistic infections, CNS, cerebrovascular disease, chronic kidney disease, cognitive impairment, and end-stage renal disease, which were combined using the AND, OR, and NOT operators. Finally, a meta-analysis was conducted in STATA14 statistical software. Based on the random effect model, the total prevalence of neurologic complications in 4674 patients who had undergone the renal transplantation surgery was 7.9% (95% confidence interval [CI]:7.2%,8.7%, I2 = 90.1%). The prevalence of infectious, non-infectious and treatment associated neurologic complications was 9.5% (95% CI -8.9, 10.2), 91.8% (95% CI -91.3, 92.4) and 97% (95% CI-95.7%,98.4%) of all neurologic complications in renal transplant patients, respectively. And according to the present subgroup analysis, peripheral neuropathy with a prevalence about 30% (29%) (95% CI -27.6%, 30.4%, I2 = 99.4%) was the most common neurological disorder in renal transplant patients followed by tremor with a prevalence of 19.5% (CI -17.6%, 21.3%, I2 = 97.1%), cerebrovascular events with a prevalence of 15.1% (95% CI -13.9%, 16.4%, I2 = 96.5%), encephalopathy with the prevalence of 13% (95% CI -12%, 14%, I2 = 99.3%), headache with a prevalence of 8.3% (95% CI -6.8%, 9.8%, I2 = 97.3%) and seizure with a prevalence of 7.4% (CI - 6.5%, 8.3%, I2 = 94.6%). The results of the present systematic review and meta-analysis, suggests that post-kidney transplantation neurological disorders, with a prevalence rate about 8%, are relatively common; most of them are caused by immunosuppressive drugs and can be treated by decreasing the dose or switching the immunosuppressive drugs. Neurological disorders are associated with increased mortality; thus, differential diagnosis should be conducted for each individual patient with neurological symptoms after transplantation. It is important for all health care providers to become familiar with the symptoms of neurological disorders that may occur after organ transplants. Recognizing and monitoring these symptoms can reduce the risk of death in kidney transplant recipients. Further research is needed to help the transplant community to identify these issues and problems better in order to achieve the ultimate goal of helping renal patients and sending them back into their normal lives.

Abstract
Renal transplant is the most common organ transplant in the United States, and the frequency of kidney transplants continues to rise as transplant offers improved survival and quality of life compared to dialysis. However, complications are not uncommon and patients frequently encounter issues requiring hospitalization, especially in the first year postoperatively. Complications that arise are typically related to surgical complications, immunosuppressive medications, or infection due to immunosuppression. Neurological complications are fairly common post-operatively, and are associated with increased morbidity and mortality in this population. This review discusses the most common etiologies of neurological complications after kidney transplant, including infection, malignancy, medication related, acute neuropathy, and other neurological pathology.

Abstract
BACKGROUND AND OBJECTIVE After a kidney transplantation, all efforts are focused on graft function. However, cardiovascular and neurologic complications might lead to decreased quality of life and shortened life expectancy. Early recognition of related symptoms might be critical to successfully manage these complications. METHODS AND PATIENTS We retrospectively reviewed the medical records of patients who had undergone kidney transplantation in a tertiary center between January 2014 and December 2017. Demographic data and past medical history were systematically gathered. Symptoms related to cardiac or neurologic disorders and final diagnoses were recorded. RESULTS One hundred eighty-six patients were evaluated by a cardiologist or a neurologist in the early post-operative period or long-term follow-up. Chest pain (n = 17; 9.1%) and palpitations (n = 13; 7.0%) were the most prevalent symptoms. Coronary artery disease was diagnosed in 70.6% (n = 12) of the patients presenting with chest pain. All of the patients were treated successfully, with either antianginal drugs or percutaneous angioplasty. Atrial fibrillation was diagnosed in 53.9% (n = 7) of the patients presenting with palpitations. Headache was the most prevalent chronic neurologic symptom (n = 16; 8.6%). Transient ischemic attack occured in 7 patients (3.8%) and 5 (2.7%) patients experienced ischemic stroke. CONCLUSION Kidney transplantation is associated with short- and long-term cardiac and neurologic complications. Our findings underscore the crucial role of questioning symptoms that might be related to severe disorders. Asymptomatic patients with high risk factors must also be under scope. Attending physicians should have a low threshold for referring these patients to cardiologists and neurologists.

Abstract
Despite improvements in overall graft function and patient survival rates after solid organ transplantation, complications can lead to significant morbidity and mortality. Cardiovascular complications include heart failure, arrhythmias leading to sudden death, hypertension, left ventricular hypertrophy, and allograft vasculopathy in heart transplantation. Neurologic complications include stroke, posterior reversible encephalopathy syndrome, infections, neuromuscular disease, seizure disorders, and neoplastic disease. Acute kidney injury occurs from immunosuppression with calcineurin inhibitors or as a result of graft failure after kidney transplantation. Gastrointestinal complications include infections, malignancy, mucosal ulceration, perforation, biliary tract disease, pancreatitis, and diverticular disease. Immunosuppression can predispose to infections and malignancy.

Abstract
PURPOSE OF REVIEW Antiepileptic drugs are frequently administered to patients with HIV infection or in recipients of organ transplants. The potentially serious drug-drug interactions between the "classic" antiepileptic drugs, antiretrovirals, and immunosuppressants have been extensively studied. Evidence-based information on the second and third generation of antiepileptic drugs is almost non-existent. The purpose of this review is to analyze the pharmacokinetic profile of these newer agents to assess their potential for drug interactions with antiretrovirals and immunosuppressants. RECENT FINDINGS As a group, the newer generations of antiepileptic drugs have shown a more favorable drug interaction potential compared to the "classic" ones. A group of moderate enzyme-inducing drugs includes eslicarbazepine acetate, oxcarbazepine, rufinamide, and topiramate. These drugs are not as potent inducers as the "classic" drugs but may potentially decrease the serum concentrations of some antiretrovirals and immunosuppressants. Antiepileptic drugs with no or minimal enzyme-inducing properties include brivaracetam, gabapentin, lacosamide, lamotrigine, levetiracetam, perampanel, pregabalin, and vigabatrin. The newer generations of antiepileptic drugs have expanded the therapeutic options in patients with HIV infection or organ transplants.

Abstract
PURPOSE To summarize information on the history, incidence, clinical manifestation, best treatment, as well as prognosis of seizures in transplant recipients. METHODS In October 2017, we searched the literature on PubMed in English with the search terms: "transplantation" AND "seizure", "transplantation" AND "epilepsy", "transplantation"AND "status epilepticus", "immunosuppressant" AND "seizure", "immunosuppressant" AND "epilepsy". Publications not based on new data and original research were not included in this article. RESULTS Seizures including generalized seizures, focal seizures and status epilepticus are a common central nervous system complication after transplantation. The incidence of seizures varied between different kinds of transplantations. The reported incidence of seizures was 7%-27% in association with solid organ transplantations and 1.6%-15.4% with hematopoietic stem cell transplantation. Most of seizures appeared in the early post-transplantation period. Patients often had a favorable prognosis, however, in some conditions, recurrent or intractable seizures may occur. CONCLUSIONS The underlying pathogenesis of new-onset seizures or epilepsy in recipients of transplantation needs to be further elucidated. In addition, more information is required from prospective studies and research focusing on therapeutic strategies.

Abstract
Acute hepatic encephalopathy has significant morbidity and mortality in liver transplant recipients unless it is promptly treated. We evaluated the brain magnetic resonance (MR) imaging findings associated with acute hepatic encephalopathy in transplant recipients. We retrospectively reviewed the clinical and imaging data and outcomes of twenty-five liver transplant patients (16 male; mean age, 49.3 years) with clinically diagnosed acute hepatic encephalopathy and forty liver transplant patients (20 males; mean age, 45.5 years) without neurological symptoms suggestive of hepatic encephalopathy at our institution. Bilateral symmetric hyperintensities of the insular cortex and cingulate gyrus were observed in twenty-one patients (84.00%), bilateral symmetric extensive increased cortical signal intensity (involving two or more regions) was observed in 72.00% of the patients, leptomeningeal enhancement in 73.68%, and visualization of prominent venules in 52.00%. The most common symptom at diagnosis was rigidity (n = 14), and the plasma ammonia levels ranged from 68.63 to 192.16 μmol/L. After active treatment, 17 patients gradually recovered, four patients suffered from mild or moderate neurologic deficits, and four patients with widespread brain edema died. The specific brain MR imaging features were bilateral symmetric increased cortical signal intensity, especially in the insular cortex and cingulate gyrus, leptomeningeal enhancement, visualization of the prominent venules, and widespread brain edema. These features may indicate poor prognosis and should alert radiologists to the possibility of acute hepatic encephalopathy in liver transplant recipients and encourage clinicians to prepare appropriate treatment in advance.

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.

Rare Event Captured with Intracranial Pressure Monitor: Malignant Spike in Intracranial Pressure During Delayed Chest Closure in Heart-Transplant Patient with Ischemic Stroke.

[PMID: 29597018 DOI: 10.1016/j.wneu.2018.03.135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2017] [Revised: 03/18/2018] [Accepted: 03/19/2018] [Indexed: 10/17/2022]
Abstract
BACKGROUND Patients with open chest wounds, either related to trauma or cardiothoracic procedures, are subjected to significant physiologic alterations when undergoing chest wound closure. Sudden increased intrathoracic pressure at closure decreases venous return from the brain to the heart; consequently the total blood volume in the ridged skull increases, resulting in increased intracranial pressure (ICP). Patients with intact cerebrovascular autoregulation can compensate for these sudden changes by adjusting cerebral blood flow to maintain physiologic ICP. In cases where the autoregulatory mechanisms are compromised, such as stroke or trauma, the ICP can become pathologically elevated. If the patient does not have an ICP monitor, the spike in ICP can go unrecognized, compromising cerebral perfusion pressure and resulting in increased morbidity and mortality. CASE DESCRIPTION Herein we describe a case of pathologic elevations in ICP captured with an ICP monitor at the time of chest wound closure in a patient with delayed chest wound closure after orthotopic heart transplant and comorbid embolic stroke. CONCLUSIONS This case report demonstrates the potential utility of ICP monitoring in patients with impaired cerebrovascular autoregulation with open and manipulated chest wounds from transplant or trauma.

Abstract
BACKGROUND Major neurologic events (MNEs) after heart transplantation (HTx) and their effect on survival have not been well described in children. In this study we aimed to characterize early MNEs (stroke, isolated seizures not from stroke and posterior reversible leukoencephalopathy [PRES] within 1 year after primary pediatric HTx) and evaluate their impact on 1-year post-HTx survival. We hypothesized that early an MNE after HTx is associated with decreased 1-year patient survival. METHODS We performed a pediatric, single-center, retrospective analysis of 345 consecutive patients aged 0 to 22 years who underwent primary HTx during the period from November 1, 1994 to October 31, 2015. Characteristics were compared between patients with and without early MNEs. RESULTS Nineteen percent (65 of 345) of patients had an MNE within 1 year after HTx (median 9 days, interquartile range [IQR] 4 to 23 days). Freedom from early MNE was 97%, 85% and 80% at 1, 6 and 12 months, respectively. Of the total 65 events, stroke comprised 55.4% (n = 36), isolated seizure 29.2% (n = 19) and PRES 15.4% (n = 10). With multiple logistic regression, previous neurologic disease, infection requiring intravenous antibiotic therapy and post-operative drug-treated hypertension were found to be significant risk factors for early MNEs. Stroke (hazard ratio 4.1, IQR 2.3 to 7.6, p < 0.0001), but not seizures and PRES, was associated with decreased 1-year patient survival. CONCLUSIONS Major neurologic events are common after pediatric HTx and usually occur within the first few weeks. Early stroke was associated with decreased 1-year survival. Potentially modifiable factors, including prior neurologic event, drug-treated hypertension and infection, were associated with increased risk of developing early MNEs.

Abstract
Ceftriaxone is a widely used third-generation cephalosporin showing advantageous pharmacokinetic properties and a broad antimicrobial spectrum. We herein report a case of ceftriaxone-induced neurotoxicity in a 56-year-old man on hemodialysis. Seven days after initiating high-dose ceftriaxone, the patient developed impaired consciousness along with facial myoclonus and sporadic phonation. The symptoms clearly disappeared shortly after withdrawal of the drug. Ceftriaxone is considered a safe antibiotic for patients with renal insufficiency, since it is excreted via both haptic and renal pathways. Physicians should note that antibiotic-associated encephalopathy may develop in patients administered ceftriaxone, especially in those complicated with renal dysfunction.

Abstract
The aim of this study was to evaluate the risk factors, clinical implications, and prognosis of new-onset seizures that occurred after pediatric liver transplantation, and to assess the efficacy of levetiracetam treatment. The clinical and laboratory data of liver transplanted 28 children who had seizures after liver transplantation and specifically of 18 children who received levetiracetam were analyzed retrospectively. Sixteen patients (88.9%) remained seizure-free and in 2 (11.1%), more than 50% reduction in seizures were detected with levetiracetam treatment. In conclusion, seizures are generally the most common complication by a spectrum of seizure types, and sometimes cause symptomatic epilepsy. The most common risk factors for seizures in transplant recipients is immunosuppressant toxicity. Currently, there isn't a specific treatment involving the transplant patient population. Levetiracetam may be preferable in pediatric patients as it's reliable for liver disease and has advantages in the treatment of postoperative seizures due to its intravenous usage.
