Abstract
Introduction Nonalcoholic fatty liver disease (NAFLD) presents as a multisystem disorder, heightening the risk of developing type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVDs). Occupation emerges as a significant factor influencing the occurrence of NAFLD. Research indicates that individuals engaged in shift work face an elevated risk of NAFLD, alongside obesity and T2DM, attributed to disruptions in their circadian rhythm, which precipitate hepatic steatosis and inflammation. Remarkably, peripheral neuropathy has been observed in conjunction with advanced liver disorders and NAFLD in the general population. However, the correlation between NAFLD and peripheral neuropathy remains unestablished in shift workers. Objective To identify NAFLD in seemingly healthy rotating shift workers and assess any potential impact of NAFLD on nerve function in this demographic. Methods This cross-sectional study involved 73 apparently healthy nonalcoholic security guards (aged 35 to 60 years) working in rotating shifts. The study included a comprehensive assessment, beginning with a medical history, an evaluation of physical activity, and anthropometric measurements. Confirmation of NAFLD was achieved through abdominal ultrasonography (USG), followed by the analysis of biochemical parameters. Motor and sensory nerve conduction studies (NCS) were conducted on participants with normal vitamin B12 levels using the Aleron electromyograph (EMG) machine (Recorders and Medicare Systems Private Ltd, Budanpur, India). The evaluation encompassed the Median and Common Peroneal motor nerves, as well as Median and Sural sensory nerves. Recorded parameters for motor nerves included distal motor latency (DML), compound muscle action potential (CMAP) amplitude, conduction velocity (CV), and F-wave minimum latency (F-wave), while sensory nerve parameters comprised sensory onset latency (SOL), sensory nerve action potential (SNAP) amplitude, and CV. Results Among 73 healthy security guards working in rotating shifts, 76.1% were diagnosed with NAFLD through abdominal ultrasound. Following participant withdrawals and exclusions due to vitamin B12 deficiency, a comparison of NCS parameters between NAFLD (n=24) and Non-NAFLD (n=12) groups revealed no significant disparities in motor or sensory parameters, except for a slightly diminished CMAP amplitude in the peroneal nerve of NAFLD subjects (8.21±2.83mV vs ±10.22±2.30 mV, p< 0.040). However, these differences fell within normal ranges, indicating no notable impact on peripheral nerve conduction in the presence of NAFLD. Conclusion The results indicate a high prevalence of NAFLD among individuals working rotating shifts. Moreover, the investigation suggests that despite the presence of NAFLD, there is no discernible influence on motor and sensory peripheral nerve conduction, particularly in common peroneal, median, and sural nerves.

J Clin Exp Hepatol 2024; 14:101291. [PMID: 38544766 PMCID: PMC10964076 DOI: 10.1016/j.jceh.2023.10.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Accepted: 10/01/2023] [Indexed: 06/24/2024] Open
Abstract
BACKGROUND Cirrhosis is a significant cause of morbidity and mortality globally and in India. This systematic review and meta-analysis aimed to ascertain the etiological spectrum and changing trends of cirrhosis in India. METHODS We searched electronic databases, including Pubmed/Medline, Scopus, and Embase. We included original studies that reported the etiology of cirrhosis in the Indian population. RESULTS We included 158 studies (adults: 147, children: 11). The overall pooled estimate of alcohol as a cause of cirrhosis in adults was 43.2% (95% confidence interval (CI) 39.8-46.6%; I2 = 97.8%), followed by nonalcoholic fatty liver disease (NAFLD)/cryptogenic in 14.4%, 95% CI (11.7-17.3%; I2 = 98.4%), hepatitis B virus (HBV) in 11.5%, 95% CI (9.8-13.3%; I2 = 96.6%), and hepatitis C virus (HCV) in 6.2%, 95% CI (4.8-7.8%; I2 = 97.2%) of the included patients. The most common cause of cirrhosis in all zones was alcohol-related. Comparison of etiologies over time revealed a reduction in the viral hepatitis-related and an increase in the proportion of alcohol-related and NAFLD/cryptogenic-related cirrhosis. The overall pooled estimates of various etiologies in children were: HBV in 10.7%, 95% CI (4.6-18.7%; I2 = 91.0%), NAFLD/Cryptogenic in 22.3%, 95% CI (9.0-39.2%; I2 = 96.7%), and HCV in 2.0%, 95% CI (0.0-8.5%; I2 = 94.6%). CONCLUSIONS Alcohol is the most common etiology of cirrhosis in adults in India. The proportions of alcohol and NAFLD-related cirrhosis are increasing, and those of viral hepatitis-related cirrhosis are reducing. The results of our meta-analysis will help formulate health policies and the allocation of resources.

Abstract
Chronic pain is highly prevalent in patients with cirrhosis and is associated with poor health-related quality of life and poor functional status. However, there is limited guidance on appropriate pain management in this population, and pharmacologic treatment can be harmful, leading to adverse outcomes, such as gastrointestinal bleeding, renal injury, falls, and hepatic encephalopathy. Chronic pain can be categorized mechanistically into three pain types: nociceptive, neuropathic, and nociplastic, each responsive to different therapies. By discussing the identification, etiology, and treatment of these three mechanistic pain descriptors with a focus on specific challenges in patients with cirrhosis, we provide a framework for better tailoring treatments, including nonpharmacologic therapies, to patients' needs.

Abstract
Schistosomiasis is a tropical parasitic disease, in which the major clinical manifestation includes hepatosplenomegaly, portal hypertension, and organs fibrosis. Clinically, treatment of schistosomiasis involves the use of praziquantel (PZQ) and supportive care, which does not improve the patient's outcome as liver injuries persist. Here we show the beneficial effects of using PZQ in combination with Schisandrin B (Sch B). Concomitant treatment with PZQ and Sch B resulted in a significant improvement of hepatosplenomegaly and fibrosis, compared with single-agent treatment. We also demonstrated that PZQ-Sch B treatment ameliorates injuries in the lungs and intestine better than the sole use of PZQ or Sch B. In addition, PZQ-Sch B treatment improves the survival of S. mansoni-infected mice, and the treatment combination yields better therapeutic outcomes, as indicated by a partial improvement in neurological function. These results were accompanied by a reduction in neurological injuries. Collectively, we suggest that PZQ-Sch B concomitant therapy may be useful to alleviate schistosomiasis-associated liver injuries and prevent systemic complications.

Abstract
Abstract
Background
Peripheral neuropathy is an underestimated problem of compensated liver cirrhosis despite its negative effect on quality of life. The aim was to assess the role of meticulous electrophysiological screening (nerve conduction responses and quantitative motor unit potential analysis) of subclinical peripheral nerve dysfunction in patients with compensated cirrhosis and also to explore its relations with different characteristics of liver disease. Severity of cirrhosis was assessed by Child–Pugh and albumin-bilirubin (ALBI) scores.
Results
Prevalence of hepatic neuropathy (HN) was 82%. It involved sensory and motor fibers (66%), and its pathophysiology was axonal (53.7%) or mixed axonal and demyelinating (46.3). The most sensitive discriminating tests were ulnar sensory conduction velocity (area under curve (AUC) = 0.915) and peak latency (AUC = 0.887), peroneal motor conduction velocity (AUC = 0.885), ulnar distal motor latency (AUC = 0.842), and first dorsal interosseous number of phases (AUC = 0.736). HN showed significant correlation with the severity of liver disease assessed by both child (P = 0.029) and ALBI (P = 0.016) scores and also correlated with the low serum albumin level (P = 0.001).
Conclusions
Subclinical mild axonal polyneuropathy is very common in post-hepatitis C compensated cirrhosis picked up by meticulous electrophysiological testing, and it is related to severity of liver cirrhosis and low serum albumin level.

Abstract
The brain influences liver metabolism through many neuroendocrine and autonomic mechanisms that have evolved to protect the organism against starvation and hypoglycemia. Unfortunately, this effective way of preventing death has become dysregulated in modern obesogenic environments, although the pathophysiological mechanisms behind metabolic dyshomeostasis are still unclear. In this Mini-Review, we provide our thoughts regarding obesity and type 2 diabetes as diseases of the autonomic nervous system. We discuss the pathophysiological mechanisms that alter the autonomic brain-liver communication in these diseases, and how they could represent important targets to prevent or treat metabolic dysfunctions. We discuss how sympathetic hyperactivity to the liver may represent an early event in the progression of metabolic diseases and could progressively lead to hepatic neuropathy. We hope that this discussion will inspire and help to frame a model based on better understanding of the chronology of autonomic dysfunctions in the liver, enabling the application of the right strategy at the right time.

Abstract
Liver cirrhosis is a global health problem that can be associated with several neurological manifestations. We aimed to assessment of the relation between the severity of the liver cirrhosis and the neurological symptoms, nerve conduction studies (NCS), as well as detecting subclinical neuropathic affection using motor unit number estimation (MUNE) technique. This cross-sectional study was conducted on 56 cirrhotic patients and 61 age- and sex-matched healthy controls. Neurological manifestations, Child-Pugh classification, Model for End-Stage Liver Disease score, NCS and MUNE using a modified spike-triggered averaging technique were studied. Forty-five (80.3%) of the cirrhotic patients had neurological manifestations. Muscle cramps were the most frequently reported manifestation, followed by fatigue and then numbness. NCS abnormality was significantly related to the presence of neurological symptoms (p < 0.001) and not only to peripheral numbness. Only fatigue was significantly related to the lower MUNE values (p < 0.017). Child-Pugh classification progression was significantly related to the presence of fatigue and abnormal NCS results (p < 0.001); no similar relation was detected between the Child-Pugh classification and the MUNE value (p = 0.103). Higher MELD scores were significantly related to NCS abnormalities (p = 0.014) and negatively correlated, although not significantly, with the MUNE values (r = -0.246 and p = 0.067). The progression of liver cirrhosis was related to the presence of neurological manifestations and nerve conduction abnormalities. Nerve conduction abnormalities may be present even in the absence of clinical numbness. A decline in motor unit number could explain the pathophysiology of fatigue in cirrhotic patients.

Abstract
We investigated the susceptibility of type I and type II skeletal myofibres to atrophy in hens with hepatic fibrosis induced by bile duct ligation (BDL). Seven hens, approximately 2 years old, were randomly assigned to BDL (n = 4) and sham surgery (SHAM) (n = 3) groups. Mean body weight and mean liver weight as a percentage of mean body weight were significantly lower in the BDL group than in the SHAM group at 4 weeks post surgery (P = 0.002, P = 0.005, respectively). Mean plasma aspartate aminotransferase activity was slightly higher, while total cholesterol (P <0.001), total bilirubin (P = 0.022) and NH3 (P = 0.048) concentrations were significantly higher in the BDL group than in the SHAM group. Liver lesions were induced in all hens in the BDL group. The weights of the pectoralis (PCT) (P = 0.049) and flexor perforans et perforatus digiti III (FPPD III) muscles (P = 0.006) as a percentage of body weight were significantly decreased in the BDL group. A significantly reduced mean myofibre cross-sectional area in the PCT of BDL hens (P = 0.005) was indicative of atrophy. No significant differences were observed in the fibre type composition of the PCT, supracoracoideus or FPPD III muscles between the SHAM and BDL groups. However, there was an approximate 43% increase in the number of type I fibres in the femorotibialis lateralis of the BDL group and small angular type II fibres and large round type I fibres in this muscle were characteristic of peripheral neuropathy. The results suggest that type II fibres are more susceptible to atrophy than type I fibres in this model of hepatic fibrosis.

Sarcopenia Induced by Chronic Liver Disease in Mice Requires the Expression of the Bile Acids Membrane Receptor TGR5. Int J Mol Sci 2020; 21:ijms21217922.

Abstract
Sarcopenia is a condition of muscle dysfunction, commonly associated with chronic liver disease (CLD), characterized by a decline in muscle strength, the activation of the ubiquitin-proteasome system (UPS), and oxidative stress. We recently described a murine model of CLD-induced sarcopenia by intake of hepatotoxin 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), which presents an increase in plasma bile acids (BA). BA induced skeletal muscle atrophy through a mechanism dependent on the Takeda G protein-coupled receptor 5 (TGR5) receptor. In the present study, we evaluated the role of TGR5 signaling in the development of sarcopenia using a model of DDC-induced CLD in C57BL6 wild-type (WT) mice and mice deficient in TGR5 expression (TGR5−/− mice). The results indicate that the decline in muscle function and contractibility induced by the DDC diet is dependent on TGR5 expression. TGR5 dependence was also observed for the decrease in fiber diameter and sarcomeric proteins, as well as for the fast-to-slow shift in muscle fiber type. UPS overactivation, indicated by increased atrogin-1/MAFbx (atrogin-1) and muscle RING-finger protein-1 (MuRF-1) protein levels and oxidative stress, was abolished in tibialis anterior muscles from TGR5−/− mice. Our results collectively suggest that all sarcopenia features induced by the DDC-supplemented diet in mice are dependent on TGR5 receptor expression.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a pathology that contains a broad liver dysfunctions spectrum. These alterations span from noninflammatory isolated steatosis until nonalcoholic steatohepatitis (NASH), a more aggressive form of the disease characterized by steatosis, inflammatory status, and varying liver degrees fibrosis. NAFLD is the most prevalent chronic liver disease worldwide. The causes of NAFLD are diverse and include genetic and environmental factors. The presence of NASH is strongly associated with cirrhosis development and hepatocellular carcinoma, two conditions that require liver transplantation. The liver alterations during NAFLD are well described. Interestingly, this pathological condition also affects other critical tissues and organs, such as skeletal muscle and even the cardiovascular, renal, and nervous systems. Oxidative stress (OS) is a harmful state present in several chronic diseases, such as NAFLD. The purpose of this review is to describe hepatic and extrahepatic dysfunctions in NAFLD. We will also review the influence of OS on the physiopathological events that affect the critical function of the liver and peripheral tissues.

Julian T, Glascow N, Syeed R, Zis P. Alcohol-related peripheral neuropathy: a systematic review and meta-analysis. J Neurol 2018; 266:2907-2919. [PMID: 30467601 PMCID: PMC6851213 DOI: 10.1007/s00415-018-9123-1] [Citation(s) in RCA: 63] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Revised: 11/09/2018] [Accepted: 11/12/2018] [Indexed: 12/20/2022]
Abstract
The primary aim of this systematic review was to establish the prevalence, character, and risk factors of peripheral neuropathy amongst chronic alcohol abusers and to identify the most appropriate management strategies. In this review, possible pathogenetic mechanisms are also discussed. A systematic, computer-based search was conducted using the PubMed database. Data regarding the above parameters were extracted. 87 articles were included in this review, 29 case–control studies, 52 prospective/retrospective cohort studies and 2 randomised control trials, 1 cross sectional study, and 3 population-based studies. The prevalence of peripheral neuropathy amongst chronic alcohol abusers is 46.3% (CI 35.7– 57.3%) when confirmed via nerve conduction studies. Alcohol-related peripheral neuropathy generally presents as a progressive, predominantly sensory axonal length-dependent neuropathy. The most important risk factor for alcohol-related peripheral neuropathy is the total lifetime dose of ethanol, although other risk factors have been identified including genetic, male gender, and type of alcohol consumed. At present, it is unclear what the pathogenetic mechanisms for the development of neuropathy amongst those who chronically abuse alcohol are, and therefore, it is unknown whether it is attributed to the direct toxic effects of ethanol or another currently unidentified factor. There is presently sparse data to support a particular management strategy in alcohol-related peripheral neuropathy, but the limited data available appears to support the use of vitamin supplementation, particularly of B-vitamin regimens inclusive of thiamine.

Abstract
Context: Cirrhosis of liver is an important cause of morbidity and mortality and if associated with peripheral neuropathy (PN) it also poses a huge financial, psychological burden for the patients and their families. Aim: The aim of the present study was to study the magnitude of PN among subjects with cirrhosis of liver presenting to tertiary care teaching hospital in central rural India. Settings and Design: A cross-sectional study was performed in a tertiary care teaching hospital. Materials and Methods: In all patients of cirrhosis of liver irrespective of etiology, aged 15 and above, undergone clinical assessment for peripheral nervous systems damage and confirmed by nerve conduction studies. Statistical Analysis Used: We used chi square test to study associations. P value ≤0.05 was considered as significant. Crude odds ratios were computed to assess the strength of association between independent variables and dependent variables along with their 95% confidence intervals. Results: We included 207 of cirrhosis of liver patients admitted in medicine department from November 2010 through November 2013. Nearly 83% patients were male and 63.2% patients were under the age of 45 years. Common features in these patients were ascites (71%) splenomegaly (63.3%) pedal edema (61.4%) icterus (46.4%) tingling (44.9%) gastrointestinal bleeding(39.1%), ataxia (26.6%), numbness(26.6%), distal motor weakness (21.7%) and paresthesia(20.8%). Among the manifestation of peripheral nerve involvement, loss of ankle reflex was the most common feature in 51.7%, followed by loss of temperature sense 29.5%, loss of vibration sense 20.8%, loss of touch 16.4%, loss of position sense 14.5% and loss of pain in 6.3% of the patients. Peripheral neuropathy was found in 53.6% [95% CI: 46.58- 60.56] study subjects on electrophysiological study. Conclusions: Analysis of electrophysiological study shows that the PN is very common in study subjects with cirrhosis of liver, especially in male subjects, during the middle age group.

Abstract
INTRODUCTION Neurological complications occur in a large number of patients with chronic hepatitis C virus (HCV) infection and range from peripheral neuropathy to cognitive impairment. We studied the association between neuropathy and HCV-related chronic liver disease. METHOD Fifty patients with HCV-related chronic liver disease were enrolled in this prospective case-control study. Patients were classified into two groups: mild and severe corresponding to a model for end-stage liver disease (MELD) score <14 and a MELD score >14, respectively. Complete neurological examination and nerve conduction studies have been done for all patients. All patients in addition to 25 healthy control subjects were tested for their serum B12 levels. RESULTS Twenty-two percent of patients had sensory abnormality, 18 % had motor abnormality, while 10 % had both sensory and motor abnormalities. Autonomic function tests and nerve conduction studies revealed that 23 patients (46 %) had evidence of neuropathy and 10 patients (20 %) had both peripheral and autonomic neuropathy. Neuropathies were not related to the severity of the liver disease. Serum B12 level had a very wide range among patients with no relation between its level and neuropathy. Vitamin B12 level was significantly and directly correlated to MELD score and age. CONCLUSION Peripheral and autonomic neuropathy has high prevalence in patients with HCV-related chronic liver disease. On the other hand, vitamin B12 level is high in those patients and there is no role for vitamin B12 in the liver cirrhosis-related neuropathy.

Abstract
We report herein an autopsy case of portal-systemic encephalopathy (PSE) presenting with diffuse tissue rarefaction in the cerebral deep white matter. Clinically, the patient showed recurrent episodes of unconsciousness, abnormal behavior and urinary incontinence, as well as flapping tremor. Cognitive impairment and peripheral neuropathy developed following recurrent episodes. Although conventional arterial portography revealed a small portal-systemic collateral vessel of a left gastro-renal venous shunt, abdominal CT and liver biopsy showed no evidence of liver cirrhosis and serum ammonia level showed a mild increase. T2-weighted MRI demonstrated symmetrical signal hyperintensities in the deep white matter. Neuropathological findings showed Alzheimer type II astrocytes in the deep layers of the cerebral cortices and severe tissue rarefaction with no or slight reactive astrocytosis in the subcortical and deep white matter. These white matter changes have been reported infrequently in patients with PSE. The present case suggests that chronic PSE without liver cirrhosis may develop diffuse white matter lesions.

Abstract
AIM To present magnetic resonance imaging (MRI) findings of non-traumatic peroneal nerve palsy and to evaluate the usefulness of MRI in patients with non-traumatic peroneal nerve palsy. MATERIALS AND METHODS In a retrospective study, 11 consecutive patients presenting with peroneal nerve palsy were included. MR images of the lower leg and electrophysiological examinations were also reviewed. The cause of peroneal nerve palsy was determined on the basis of MRI findings and was evaluated using electrophysiological data. Nine patients with causative lesions detected on MRI, underwent surgery. RESULTS Clinical examination and electromyography (EMG) disclosed 11 peroneal lesions. MRI and EMG revealed three types of signal intensity change, i.e. deep peroneal nerve palsy type, common peroneal nerve palsy type, and superficial peroneal nerve palsy type. The MRI and EMG findings were in agreement in seven (65%) of the 11 study patients. In nine patients the causative lesions were identified using MRI, including ganglion cyst (n=6), osteochondroma (n=1), synovial cyst (n=1), and aneurysm (n=1). CONCLUSION Ganglion cyst is the most common cause of non-traumatic peroneal nerve palsy. MRI offers a noninvasive method for obtaining useful information to assess, localize, and monitor peripheral peroneal nerve palsy.

Abstract
BACKGROUND Thalidomide has been reported to have antitumor activity for treating metastatic hepatocellular carcinoma (HCC). We evaluated the safety and efficacy of using thalidomide for treating selected patients with unresectable or metastatic HCC, and their disease was refractory to systemic chemotherapy. METHODS Eight patients with measurable and metastatic HCC that had progressed with prior systemic chemotherapy and who desired further active therapy were enrolled in this study. Thalidomide was given orally at bedtime and it was started at 200 mg/day with no further dose escalation. The response was measured at 2-month intervals. RESULTS The median age was 44 years (range: 34-52 years) and all the patients had received doxorubicin-based systemic chemotherapy prior to their enrollment. Each patient received thalidomide for a median of 152 days (range: 5-422 days). One partial response was observed (12.5%, 95% CI; 0-42%) along with 4 cases of stable diseases. The most commonly encountered toxicity was somnolence; grade 3 somnolence was noted for one patient, which led to treatment discontinuation. Skin rash was observed in one responding patient. CONCLUSIONS The results indicate that thalidomide may feasibly offer disease stabilization to metastatic HCC patients. Further dose escalation of thalidomide, or its combination with other chemotherapeutic agents, may be of interest and this should be investigated for treating patients with metastatic HCC.

Abstract
Between 10 and 20% of adult liver transplants are performed for end-stage alcoholic liver disease. Severe extrahepatic end-organ damage from alcoholism (cardiomyopathy, pancreatitis, central nervous system injury, and neuropathy) is widely regarded as an absolute contraindication to liver transplantation, despite a lack of data on the effect of transplantation on these complications. We describe such a patient who presented with decompensated alcoholic liver disease and moderately severe peripheral neuropathy. Both his liver failure and neuropathy progressed despite 9 months abstinence and intensive nutritional support. By 12 months post-transplant, however, this patient had regained almost normal muscle strength, with associated recovery in sensory and motor conduction velocities. Direct alcohol toxicity, nutritional and vitamin deficiencies, and liver failure were all likely etiologic factors in this patient's neuropathy. In conclusion, this case suggests that peripheral neuropathy in a patient with alcoholic cirrhosis may resolve following liver transplantation and should not constitute a contraindication to transplantation, even when it is disabling.
