Abstract
OBJECTIVE The purpose of this manuscript is to identify the pathophysiology of the metabolic abnormalities observed in cirrhosis and to uncover associations, if any, to its complications, such as sarcopenia and hepatic encephalopathy (HE). BACKGROUND Liver dysfunction in cirrhosis is known to be a precipitating factor in the disruption of many physiological pathways, specifically nutrient metabolism. As a result, affected patients are highly susceptible to derangements of processes affecting multiple classes of macro- and micronutrients, including proteins, carbohydrates, electrolytes, vitamins, and minerals. These disruptions are thought to be contributory to the pathogenesis of known complications of cirrhosis. METHODS Literature research of relevant topics was conducted for the above stated objective; sources were limited to articles from peer-reviewed journals published within the last 30 years. CONCLUSION This research established that there is positive correlation between nutrient derangements and the increased risk of complications of cirrhosis, which themselves carry significant morbidity and mortality risk. It also established that some nutrient and electrolyte abnormalities are independent indicators of prognosis and adverse outcomes, such as mortality. This also highlights the importance of comprehension of anomalous metabolism and its complications as it necessitates serious consideration in clinical care. In addition to medical management, cirrhotic patients also require ancillary assessment, such as comprehensive nutritional evaluation, to identify and treat reversible nutritional derangements. This consideration provides the best opportunity to achieve maximal health outcomes in the cirrhotic patient population.

Baseline serum cystatin C as a marker of acute kidney injury in patients with acute-on-chronic liver failure. Indian J Gastroenterol 2021; 40:563-571. [PMID: 34981441 DOI: 10.1007/s12664-021-01201-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Accepted: 05/24/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND A creatinine-based estimation of the renal function lags behind the onset of disease process. Cystatin C is a new marker for acute kidney injury (AKI). However, data are limited in patients with acute-on-chronic liver failure (ACLF). We evaluated serum cystatin C as an early predictor of AKI in patients with ACLF. METHODS In a prospective observational study, patients with ACLF and normal serum creatinine level were included in the study. Serum cystatin C was analyzed with the development of AKI and the disease outcome. RESULT Forty-seven patients (mean age: 43.26±16.34 years; male:female: 2.35:1) were included in the study. AKI developed in 34% of patients during the hospital stay. Receiver operating characteristic (ROC) curve analysis revealed that the best cutoff for baseline cystatin C was 1.47 mg/L with a sensitivity of 0.94 and specificity of 0.68. The cystatin C ((area under the curve [AUC]=0.853) performance was better than that of the creatinine (AUC=0.699), Child-Turcotte-Pugh (CTP) (AUC=0.661), and model for end-stage liver disease-sodium (MELD-Na) (AUC=0.641). In the univariate analysis, age, platelet count, creatinine, estimated glomerular filtration rate (eGFR)-modification of diet in renal disease (MDRD), cystatin C, and estimated glomerular filtration rate-serum cystatin C (eGFRcysC) were significantly associated with AKI in ACLF patients. Cystatin C was an independent positive predictor of AKI. Cystatin C was positively correlated with the MELD-Na scores (r=0.374 and p=0.009). CONCLUSION Our study supports previous studies reporting that serum cystatin C is a better predictor for AKI development compared to serum creatinine. Cystatin C may be used as an early marker for new-onset AKI in hospitalized patients with ACLF.

Abstract
BACKGROUND Vitamin D deficiency is often reported in people with chronic liver diseases. Improving vitamin D status could therefore be beneficial for people with chronic liver diseases. OBJECTIVES To assess the beneficial and harmful effects of vitamin D supplementation in adults with chronic liver diseases. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, Science Citation Index Expanded, and Conference Proceedings Citation Index-Science. We also searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. We scanned bibliographies of relevant publications and enquired experts and pharmaceutical companies as to additional trials. All searches were up to November 2020. SELECTION CRITERIA Randomised clinical trials that compared vitamin D at any dose, duration, and route of administration versus placebo or no intervention in adults with chronic liver diseases. Vitamin D could have been administered as supplemental vitamin D (vitamin D3 (cholecalciferol) or vitamin D2 (ergocalciferol)), or an active form of vitamin D (1α-hydroxyvitamin D (alfacalcidol), 25-hydroxyvitamin D (calcidiol), or 1,25-dihydroxyvitamin D (calcitriol)). DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We used GRADE to assess the certainty of evidence. MAIN RESULTS We included 27 randomised clinical trials with 1979 adult participants. This review update added 12 trials with 945 participants. We assessed all trials as at high risk of bias. All trials had a parallel-group design. Eleven trials were conducted in high-income countries and 16 trials in middle-income countries. Ten trials included participants with chronic hepatitis C, five trials participants with liver cirrhosis, 11 trials participants with non-alcoholic fatty liver disease, and one trial liver transplant recipients. All of the included trials reported the baseline vitamin D status of participants. Participants in nine trials had baseline serum 25-hydroxyvitamin D levels at or above vitamin D adequacy (20 ng/mL), whilst participants in the remaining 18 trials were vitamin D insufficient (less than 20 ng/mL). Twenty-four trials administered vitamin D orally, two trials intramuscularly, and one trial intramuscularly and orally. In all 27 trials, the mean duration of vitamin D supplementation was 6 months, and the mean follow-up of participants from randomisation was 7 months. Twenty trials (1592 participants; 44% women; mean age 48 years) tested vitamin D3 (cholecalciferol); three trials (156 participants; 28% women; mean age 54 years) tested vitamin D2; four trials (291 participants; 60% women; mean age 52 years) tested 1,25-dihydroxyvitamin D; and one trial (18 participants; 0% women; mean age 52 years) tested 25-hydroxyvitamin D. One trial did not report the form of vitamin D. Twelve trials used a placebo, whilst the other 15 trials used no intervention in the control group. Fourteen trials appeared to be free of vested interest. Eleven trials did not provide any information on clinical trial support or sponsorship. Two trials were funded by industry. We are very uncertain regarding the effect of vitamin D versus placebo or no intervention on all-cause mortality (risk ratio (RR) 0.86, 95% confidence interval (CI) 0.51 to 1.45; 27 trials; 1979 participants). The mean follow-up was 7 months (range 1 to 18 months). We are very uncertain regarding the effect of vitamin D versus placebo or no intervention on liver-related mortality (RR 1.62, 95% CI 0.08 to 34.66; 1 trial; 18 participants) (follow-up: 12 months); serious adverse events such as hypercalcaemia (RR 5.00, 95% CI 0.25 to 100.8; 1 trial; 76 participants); myocardial infarction (RR 0.75, 95% CI 0.08 to 6.81; 2 trials; 86 participants); thyroiditis (RR 0.33, 95% CI 0.01 to 7.91; 1 trial; 68 participants); circular haemorrhoidal prolapse (RR 3.00, 95% CI 0.14 to 65.9; 1 trial; 20 participants); bronchopneumonia (RR 0.33, 95% CI 0.02 to 7.32; 1 trial 20 participants); and non-serious adverse events. The certainty of evidence for all outcomes is very low. We found no data on liver-related morbidity such as gastrointestinal bleeding, hepatic encephalopathy, hepatorenal syndrome, ascites, or liver cancer. There were also no data on health-related quality of life. The evidence is also very uncertain regarding the effect of vitamin D versus placebo or no intervention on rapid, early, and sustained virological response in people with chronic hepatitis C. AUTHORS' CONCLUSIONS Given the high risk of bias and insufficient power of the included trials and the very low certainty of the available evidence, vitamin D supplementation versus placebo or no intervention may increase or reduce all-cause mortality, liver-related mortality, serious adverse events, or non-serious adverse events in adults with chronic liver diseases. There is a lack of data on liver-related morbidity and health-related quality of life. Further evidence on clinically important outcomes analysed in this review is needed.

Abstract
Orf is an epithelial zoonotic infectious disease caused by orf virus (ORFV). Mounting studies have shown that IL-17-driven neutrophil inflammation plays a central role in inflammatory skin diseases. However, whether IL-17 plays a similar role and how does it work in the pathogenesis of orf is unclear. In this study, we found that during orf development, numerous inflammatory cells, especially neutrophils, infiltrated in the damaged lip tissue. Meanwhile, the production of IL-17 was increased in the lesion site. Further evidence showed that IL-17 potently stimulated the production of several chemokines that are crucial for neutrophil migration. In addition, IL-17 was mostly produced by CD4+ T cells and gamma delta T (γδ T) cells of the skin. In conclusion, the present study highlighted a critical role of IL-17-driven inflammation in the pathogenesis of orf and suggested that this cytokine may be a potential therapeutic target of this disease in goats.

Abstract
Malnutrition and sarcopenia that lead to functional deterioration, frailty, and increased risk for complications and mortality are common in cirrhosis. Sarcopenic obesity, which is associated with worse outcomes than either condition alone, may be overlooked. Lifestyle intervention aiming for moderate weight reduction can be offered to obese compensated cirrhotic patients, with diet consisting of reduced caloric intake, achieved by reduction of carbohydrate and fat intake, while maintaining high protein intake. Dietary and moderate exercise interventions in patients with cirrhosis are beneficial. Cirrhotic patients with malnutrition should have nutritional counseling, and all patients should be encouraged to avoid a sedentary lifestyle.

Abstract
Malnutrition and sarcopenia are common in patients with chronic liver disease and are associated with increased risk of decompensation, infections, wait-list mortality and poorer outcomes after liver transplantation. Assessment of nutritional status and management of malnutrition are therefore essential to improve outcomes in patients with chronic liver disease. This consensus statement of the Indian National Association for Study of the Liver provides a comprehensive review of nutrition in chronic liver disease and gives recommendations for nutritional screening and treatment in specific clinical scenarios of malnutrition in cirrhosis in adults as well as children with chronic liver disease and metabolic disorders.

J Family Med Prim Care 2020; 9:798-803. [PMID: 32318423 PMCID: PMC7114044 DOI: 10.4103/jfmpc.jfmpc_1084_19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 01/22/2020] [Accepted: 01/23/2020] [Indexed: 11/04/2022] Open
Abstract
Background Hepatic encephalopathy (HE) is an established clinical manifestation in chronic liver disease (CLD). It is associated with various factors including gastrointestinal bleed, constipation, and dyselectrolemia. Recently 25-hydroxyvitamin D (25-OHD) deficiency has been identified as one of the factors associated with the development of HE. The current study was aimed to assess the level of 25-OHD in patients with CLD and hepatic encephalopathy and the relationship between 25-OHD deficiency and hepatic encephalopathy. Materials and Methods This cross-sectional study included 100 subjects of either sex between 18 and 60 years of age, diagnosed as CLD on the basis of ultrasonography with hepatic encephalopathy and 50 age, sex-matched CLD subjects without encephalopathy. Hemogram, hepatic and renal functions, serum electrolytes, coagulation profile, and serum 25-hydroxyvitamin D levels were recorded. Results The baseline variables were matched for age, sex, hepatic and kidney function, and coagulation profiles. The hemoglobin (P = 0.002) and platelet count (P = 0.0003) were significantly lower in subjects with HE. The mean level of 25-OHD was significantly lower in subjects with HE as compared to the control group (25.62 ± 21.94 nmol/L vs 37.44 ± 18.61 nmol/L, P < 0.001). The mean 25-OHD level was 30.64 ± 21.64 nmol/L in grade 1 HE, 12.03 ± 11.05 nmol/L in grade 3 with P < 0.0001, and 18.8 ± 16.88 nmol/L in grade 4 with P < 0.0001 when compared to grade 1. Moderate and severe deficiency of 25-OHD level was significantly associated with higher grades of HE, i.e. grades 3 and 4 (P < 0.0001). There was a significant negative correlation between 25-OHD levels and worsening grades of hepatic encephalopathy (person's correlation coefficient r = -0.354; P = 0.0003). Conclusion In this cohort of North Indian population, serum 25-OHD level was significantly lower in patients with CLD and HE. The levels of 25-OHD showed a significant negative correlation with hepatic encephalopathy.

Abstract
Hepatic encephalopathy (HE) is a potentially reversible neurocognitive condition seen in patients with advanced liver disease. The overt form of HE has been reported in up to 45% of patients with cirrhosis. This debilitating condition is associated with increased morbidity and mortality and imposes a significant burden on the caregivers and healthcare system. After providing an overview of HE epidemiology and pathophysiology, this review focuses on the interaction of HE and frailty, nutrition requirements and recommendations in cirrhotic patients with HE, and current dietary and pharmacologic options for HE treatment.

Abstract
AIM Vitamin D plays an important role in the pathological process of chronic liver disease (CLD), and the degree of vitamin D deficiency is related to the severity of CLD. The aim of our study was to investigate the association between severe vitamin D deficiency and the risk of all-cause mortality in patients with liver cirrhosis (LC). METHODS The PubMed, Embase, and Cochrane Library databases were searched systematically for eligible studies from the earliest available date to 15 January 2019. The exposure and outcome of interest was serum vitamin D levels and all-cause mortality, respectively. The pooled risk ratio (RR) values and their 95% confidence intervals (CIs) were calculated through a meta-analysis. RESULTS Eight studies published from March 2013 to January 2019 were included, involving 1,339 patients with LC. The meta-analysis showed that a severe serum vitamin D deficiency was associated with an increased risk of mortality in patients with LC (RR = 1.79; 95% CI 1.44-2.22; P < 0.01). CONCLUSION Our meta-analysis confirmed the association between severe vitamin D deficiency and mortality risk, suggested serum vitamin D level as a new index to predict the prognosis, and emphasized the importance of vitamin D supplementation in LC patients.

Abstract
Viral infections cause substantial human morbidity and mortality, and are a significant health burden worldwide. Following a viral infection, the host may initiate complex antiviral immune responses to antagonize viral invasion and replication. However, proinflammatory antiviral immune responses pose a great threat to the host if not properly held in check. Interleukin (IL)-17 is a pleiotropic cytokine participating in a variety of physiological and pathophysiological conditions, including tissue integrity maintenance, cancer progression, autoimmune disease development and, more intriguingly, infectious diseases. Abundant evidence suggests that while IL-17 plays a crucial role in enhancing effective antiviral immune responses, it may also promote and exacerbate virus-induced illnesses. Accumulated experimental and clinical evidence has broadened our understanding of the seemingly paradoxical role of IL-17 in viral infections and suggests that IL-17-targeted immunotherapy may be a promising therapeutic option. Herein, we summarize current knowledge regarding the protective and pathogenic roles of IL-17 in viral infections, with emphasis on underlying mechanisms. The various and critical roles of IL-17 in viral infections necessitate the development of therapeutic strategies that are uniquely tailored to both the infectious agent and the infection environment.

Abstract
BACKGROUND Liver cirrhosis represents a substantial global burden in terms of morbidity and mortality. Observational studies have reported an increased risk of death with low circulating 25-hydroxyvitamin D concentrations in such patients. Because the occurrence of inadequate vitamin D status is very common in patients with liver cirrhosis, the aim of this study is to conduct a meta-analysis of observational studies in such patients to assess whether vitamin D deficiency increases their risk of mortality. METHODS We will search electronic databases (MEDLINE, Embase, Web of Science, CENTRAL and Google Scholar from time of inception until now), conference proceedings and conduct manual searches to identify studies eligible for inclusion. There will be no restrictions based on publication status or language, and the meta-analysis will be reported in accordance with the MOOSE guidelines. We will employ random-effects meta-analysis to assess the relationship between vitamin D deficiency and risk of mortality. Quality of studies will be judged using the Newcastle-Ottawa scale, and between-trial heterogeneity will be evaluated by means of subgroup and sensitivity analyses. DISCUSSION The study will assess the effects of serum 25-hydroxyvitamin D concentrations on mortality in patients with liver cirrhosis. The results will be published in a high-quality peer-reviewed journal. SYSTEMATIC REVIEW REGISTRATION Prospero CRD42016052007 .

Abstract
BACKGROUND Vitamin D plays a role in innate and acquired immunity. The risk for bacterial infections is increased in cirrhotic patients due to low levels of vitamin D. This study aimed to determine serum 25-(OH) vitamin D levels among cirrhotic patients in the presence and absence of infections and correlate this level with liver disease severity. METHODS This cross-sectional analytic study recruited 87 hospitalised cirrhotic patients who were divided into the following groups: group with evidence of infection (45 cases) and group without infection (42 cases). Urine analysis, ascetic fluid study and chest X-rays were performed to find the site of infection. Serum 25-(OH) vitamin D was also measured. RESULTS Vitamin D levels were lower in the cirrhotic with infection group than in the cirrhotic without infection group (17.3 ± 2.5 vs. 41.1 ± 3.1, respectively) (P-value < 0.001). Approximately 71.4% cirrhotic patients without infection had sufficient vitamin D levels, while 60% of cirrhotic patients with infection had insufficient vitamin D levels, and 28.9% had vitamin D deficiency (P-value < 0.001). Spontaneous bacterial peritonitis was the most common infection (62.2%). The cutoff point of vitamin D levels for cirrhotic patients with infection was 21 ng/mL. CONCLUSION Vitamin D deficiency was found to be an independent predictor of infection in cirrhotic patients suggesting that vitamin D supplementation may be useful in these patients. No significant correlations were found between the vitamin D level and the Child-Pugh class and MELD score among the infected group and non-infected group.

Abstract
Obesity and metabolic syndrome are considered as responsible for a condition known as the non-alcoholic fatty liver disease that goes from simple accumulation of triglycerides to hepatic inflammation and may progress to cirrhosis. Patients with obesity also have an increased risk of primary liver malignancies and increased body mass index is a predictor of decompensation of liver cirrhosis. Sarcopenic obesity confers a risk of physical impairment and disability that is significantly higher than the risk induced by each of the two conditions alone as it has been shown to be an independent risk factor for chronic liver disease in patients with obesity and a prognostic negative marker for the evolution of liver cirrhosis and the results of liver transplantation. Cirrhotic patients with obesity are at high risk for depletion of various fat-soluble, water-soluble vitamins and trace elements and should be supplemented appropriately. Diet, physical activity and protein intake should be carefully monitored in these fragile patients according to recent recommendations. Bariatric surgery is sporadically used in patients with morbid obesity and cirrhosis also in the setting of liver transplantation. The risk of sarcopenia, micronutrient status, and the recommended supplementation in patients with obesity and cirrhosis are discussed in this review. Furthermore, the indications and contraindications of bariatric surgery-induced weight loss in the cirrhotic patient with obesity are discussed.
