RESUMO

This study aimed to identify the regulatory mechanisms of white, blue, red lights on carotenoid and tocochromanol biosynthesis in mung bean sprouts. Results showed that three lights stimulated the increase of the predominated lutein (3.2-8.1 folds) and violaxanthin (2.1-6.1 folds) in sprouts as compared with dark control, as well as ß-carotene (20-36 folds), with the best yield observed under white light. Light signals also promoted α- and γ-tocopherol accumulation (up to 1.8 folds) as compared with dark control. The CRTISO, LUT5 and DXS (1.24-6.34 folds) exhibited high expression levels under light quality conditions, resulting in an overaccumulation of carotenoids. The MPBQ-MT, TC and TMT were decisive genes in tocochromanol biosynthesis, and were expressed up to 4.19 folds as compared with control. Overall, the results could provide novel insights into light-mediated regulation and fortification of carotenoids and tocopherols, as well as guide future agricultural cultivation of mung bean sprouts.

RESUMO

Background: The NAFLD decompensation risk score (the Iowa Model) was recently developed to identify patients with nonalcoholic fatty liver disease (NAFLD) at highest risk of developing hepatic events using three variables-age, platelet count, and diabetes. Aims: We performed an external validation of the Iowa Model and compared it to existing non-invasive models. Methods: We included 249 patients with NAFLD at Boston Medical Center, Boston, Massachusetts, in the external validation cohort and 949 patients in the combined internal/external validation cohort. The primary outcome was the development of hepatic events (ascites, hepatic encephalopathy, esophageal or gastric varices, or hepatocellular carcinoma). We used Cox proportional hazards to analyze the ability of the Iowa Model to predict hepatic events in the external validation (https://uihc.org/non-alcoholic-fatty-liver-disease-decompensation-risk-score-calculator). We compared the performance of the Iowa Model to the AST-to-platelet ratio index (APRI), NAFLD fibrosis score (NFS), and the FIB-4 index in the combined cohort. Results: The Iowa Model significantly predicted the development of hepatic events with hazard ratio of 2.5 [95% confidence interval (CI) 1.7-3.9, P < 0.001] and area under the receiver operating characteristic curve (AUROC) of 0.87 (CI 0.83-0.91). The AUROC of the Iowa Model (0.88, CI: 0.85-0.92) was comparable to the FIB-4 index (0.87, CI: 0.83-0.91) and higher than NFS (0.66, CI: 0.63-0.69) and APRI (0.76, CI: 0.73-0.79). Conclusions: In an urban, racially and ethnically diverse population, the Iowa Model performed well to identify NAFLD patients at higher risk for liver-related complications. The model provides the individual probability of developing hepatic events and identifies patients in need of early intervention.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver disease globally and in India. The already high burden of NAFLD in India is expected to further increase in the future in parallel with the ongoing epidemics of obesity and type 2 diabetes mellitus. Given the high prevalence of NAFLD in the community, it is crucial to identify those at risk of progressive liver disease to streamline referral and guide proper management. Existing guidelines on NAFLD by various international societies fail to capture the entire landscape of NAFLD in India and are often difficult to incorporate in clinical practice due to fundamental differences in sociocultural aspects and health infrastructure available in India. A lot of progress has been made in the field of NAFLD in the 7 years since the initial position paper by the Indian National Association for the Study of Liver on NAFLD in 2015. Further, the ongoing debate on the nomenclature of NAFLD is creating undue confusion among clinical practitioners. The ensuing comprehensive review provides consensus-based, guidance statements on the nomenclature, diagnosis, and treatment of NAFLD that are practically implementable in the Indian setting.

RESUMO

Hepatitis B virus (HBV) infection is still one kind of the infectious diseases that seriously threaten human health. Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide. HBV infection complicated with NAFLD is increasingly common. This review mainly describes the interaction between HBV infection and NAFLD, the interaction between steatosis and antiviral drugs, and the prognosis of HBV infection complicated with NAFLD. Most studies suggest that HBV infection may reduce the incidence of NAFLD. NAFLD can promote the spontaneous clearance of hepatitis B surface antigen (HBsAg), but whether it affects antiviral efficacy has been reported inconsistently. HBV infection combined with NAFLD can promote the progression of liver fibrosis, especially in patients with severe steatosis. The outcome of HBV infection combined with NAFLD predisposing to the progression of HCC remains controversial.

RESUMO

Background: Nonalcoholic fatty liver disease (NAFLD) is the commonest type of liver disease worldwide. We aimed to assess the incidence and predictors of liver-related events (LREs) and mortality in NAFLD patients. Methods: NAFLD patients (n = 957) evaluated between January 2000 and November 2021 were included. Patients were categorised as noncirrhosis (NC), compensated cirrhosis (CC) and decompensated cirrhosis (DC), and the incidence of LRE and mortality were estimated and compared. Results: The proportions of NC, CC and DC were 87.8% (n = 840), 8.8% (n = 84) and 3.4% (n = 33), respectively. The median follow-up duration was 3.9 (3.0-5.7) years, and the total cumulative duration was 4633 person-years. The incidence of LRE per 100 person-years was 0.14, 2.72 and 10.24 in patients with NC, CC and DC, respectively. The incidence of mortality was 0.12, 1.05 and 4.24 per 100 person-years, respectively, in the 3 groups. The causes of mortality in the 3 groups were liver related in 1/5 (20%), 3/4 (75%) and 6/9 (66.7%), respectively. Overall, the mortality rate was higher in those with diabetes than those without diabetes (log-rank P value = 0.005). On further analysis, diabetes was associated with poor outcomes only in NC group (log-rank P value = 0.036), and not in CC (log-rank P value = 0.353) or DC groups (log-rank P value = 0.771). On multivariate Cox proportional hazard analysis, age (hazard ratio [HR] 1.070), hypertension (HR 4.361) and DC (HR 15.036) were independent predictors of poor outcomes. Liver stiffness measurement, bilirubin, CC and DC were independent predictors of LRE. Conclusion: In our study of NAFLD from India, the incidence of LRE was found to be similar to that seen in Western studies. In NC NAFLD, diabetes was associated with poor outcomes.

RESUMO

Background: Recurrent or de novo nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are common after liver transplantation (LT) and may be associated with rapid progression to fibrosis; however, there is limited data in this regard after living donor liver transplantation (LDLT). Material and methods: This is a retrospective study at a high volume LDLT center of all liver biopsies performed in patients with post-transplant NAFLD diagnosed on ultrasound of the abdomen. Liver biopsy was indicated for raised transaminases and/or high liver stiffness on TE. The association between these prebiopsy parameters and inflammation and fibrosis on histology was analyzed. Data are shown as mean ± standard deviation or median (25-75 interquartile range). Results: The study cohort consisted of 31 males and 3 females, aged 43 ± 10 years. The LT to liver biopsy interval was 44 (28-68) months. The prebiopsy AST and ALT were 71 (38-119) and 66 (50-156), respectively. The histology suggested no nonalcoholic steatohepatitis (NASH) in 7 (20%), borderline NASH in 15 (44%), and NASH in 12 (35%) patients. A total of 15 patients (44%) had stage 1 or stage 2 fibrosis. The proportion of patients having fibrosis was significantly higher in patients with NASH (83%) compared to patients with borderline NASH (33%) or no NASH (none had fibrosis, P = 0.001). Among 18 patients who underwent TE (on FibroScan), liver stiffness was significantly higher in patients with fibrosis [18.1 (9.7-22.5)] than in those without fibrosis [9.7 (4.0-12.7); P = 0.043]. Conclusion: Over a third of the LDLT recipients with post-transplant NAFLD developed NASH, and nearly half, borderline NASH 3-5 years after transplant. Most with established NASH also had fibrosis on histology. Prevention of risk factors and early diagnosis is warranted in these patients.

RESUMO

Background: Due to lack of targeted treatment options and inconsistent utilization of histologic endpoints among clinical trials, identifying efficacious pharmacotherapies for nonalcoholic steatohepatitis [NASH] has proven challenging. Methods: A thorough systematic review and frequentist random-effects network meta-analysis was performed across all randomized clinical trials reporting a pharmacotherapeutic intervention on biopsy-proven NASH. Primary outcomes were based on the most current, up-to-date recommended histologic endpoints. Results: A total of 40 RCTs were identified including 6593 total patients. The most effective and statistically significant treatment interventions for minimum two-point improvement in NAFLD Activity Score were aldafermin 1 mg [RR 7.69, 95% CI 2.00; 29.57], vitamin E 800 IU in combination with pioglitazone 45 mg [RR 3.38, 95% CI 1.88; 6.07], pioglitazone 45 mg [RR 3.29, 95% CI 1.74; 6.22], vitamin E 800 IU [RR 2.06, 95% CI 1.33; 3.18], resmetirom 80 mg [RR 1.74, 95% CI 1.03; 2.94], obeticholic acid 25 mg [RR 1.63, 95% CI 1.32; 2.01], and obeticholic acid 10 mg [RR 1.31, 95% CI 1.02; 1.67]). The most robust pharmacotherapies for NASH resolution without worsening fibrosis were found to be aldafermin 1 mg [RR 5.77, 95% CI 1.48; 22.51], pioglitazone 45 mg [RR 2.65, 95% CI 1.43; 4.91], vitamin E 800 IU in combination with pioglitazone 45 mg [RR 2.64, 95% CI 1.36; 5.12], pioglitazone 30 mg [RR 2.46, 95% CI 1.56; 3.88], vitamin E 800 IU [RR 1.90, 95% CI 1.20; 3.00], and obeticholic acid 25 mg [RR 1.52, 95% CI 1.03; 2.23]). Obeticholic acid had a significant improvement on fibrosis. Multiple interventions were found to improve individual histologic scores across secondary outcome analyses and are detailed below. Conclusion: This novel systematic review and network meta-analysis represents the most comprehensive investigation to date regarding the pharmacotherapeutic options for biopsy-proven NASH using current recommended histologic endpoints.

RESUMO

Protein seldom performs biological activities in isolation. Understanding the protein-protein interactions' physical rewiring in response to pathological conditions or pathogen infection can help advance our comprehension of disease etiology, progression, and pathogenesis, which allow us to explore the alternate route to control the regulation of key target interactions, timely and effectively. Nonalcoholic steatohepatitis (NASH) is now a global public health problem exacerbated due to the lack of appropriate treatments. The most advanced anti-NASH lead compound (selonsertib) is withdrawn, though it is able to inhibit its target Apoptosis signal-regulating kinase 1 (ASK1) completely, indicating the necessity to explore alternate routes rather than complete inhibition. Understanding the interaction fingerprints of endogenous regulators at the molecular level that underpin disease formation and progression may spur the rationale of designing therapeutic strategies. Based on our analysis and thorough literature survey of the various key regulators and PTMs, the current review emphasizes PPI-based drug discovery's relevance for NASH conditions. The lack of structural detail (interface sites) of ASK1 and its regulators makes it challenging to characterize the PPI interfaces. This review summarizes key regulators interaction fingerprinting of ASK1, which can be explored further to restore the homeostasis from its hyperactive states for therapeutics intervention against NASH.

RESUMO

Cardiometabolic disease (CMD), characterized with metabolic disorder triggered cardiovascular events, is a leading cause of death and disability. Metabolic disorders trigger chronic low-grade inflammation, and actually, a new concept of metaflammation has been proposed to define the state of metabolism connected with immunological adaptations. Amongst the continuously increased list of systemic metabolites in regulation of immune system, bile acids (BAs) represent a distinct class of metabolites implicated in the whole process of CMD development because of its multifaceted roles in shaping systemic immunometabolism. BAs can directly modulate the immune system by either boosting or inhibiting inflammatory responses via diverse mechanisms. Moreover, BAs are key determinants in maintaining the dynamic communication between the host and microbiota. Importantly, BAs via targeting Farnesoid X receptor (FXR) and diverse other nuclear receptors play key roles in regulating metabolic homeostasis of lipids, glucose, and amino acids. Moreover, BAs axis per se is susceptible to inflammatory and metabolic intervention, and thereby BAs axis may constitute a reciprocal regulatory loop in metaflammation. We thus propose that BAs axis represents a core coordinator in integrating systemic immunometabolism implicated in the process of CMD. We provide an updated summary and an intensive discussion about how BAs shape both the innate and adaptive immune system, and how BAs axis function as a core coordinator in integrating metabolic disorder to chronic inflammation in conditions of CMD.

RESUMO

Background: Saroglitazar is a novel, dual peroxisome proliferator-activated receptors-α/γ agonist and is being investigated for the treatment of nonalcoholic fatty liver disease (NAFLD). Patients and methods: Consecutive overweight (body mass index [BMI] >23 kg/m2) patients of NAFLD, diagnosed based on controlled attenuation parameter (CAP) >248 dB/m, and attending the outpatient department of a tertiary care centre in New Delhi, were enrolled. Patients with cirrhosis (liver stiffness measurement [LSM] >13.5 kPa) and those with concomitant liver disease due to other aetiologies (alcohol, viral, etc.) were excluded. All patients received saroglitazar 4 mg/day; in addition, they were advised to reduce weight and were counselled regarding diet and exercise. At 3-month follow-up, patients were categorized into those who were able to reduce ≥5% body weight and those who could n'ot, and both these groups were compared. Results: A total of 91 patients (median age 45 years [range 18-66 years]; 81% men) were included in the study. The median BMI was 29.3 kg/m2 (range 23.6-42.2 kg/m2). The baseline median (range) aspartate transaminase, alanine transaminase, gamma glutamyl transferase, LSM and CAP values were 40 IU/dL (range 22-144 IU/dL), 48 IU/dL (range 13-164 IU/dL), 42 IU/dL (range 4-171 IU/dL), 6.7 kPa (range 3.6-13.1 kPa), and 308 dB/m (range 249-400 dB/m). All patients tolerated saroglitazar well. At 3-month, 57 patients (63%) were able to reduce ≥5% weight, whereas in the remaining 34 patients (37%), the weight reduction was <5% from baseline. Transaminases values improved in both the groups; however, LSM and CAP values improved only in patients who reduced weight. Conclusion: In overweight patients with NAFLD, a 3-month therapy with saroglitazar is able to improve transaminases but not LSM and CAP values unless accompanied by weight reduction of at least 5%. Larger randomized controlled trials are needed to document the independent effect of saroglitazar in these patients.

RESUMO

Background: Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease, which is associated with features of metabolic syndrome. NAFLD may progress in a subset of patients into nonalcoholic steatohepatitis (NASH) with liver injury resulting ultimately in cirrhosis and potentially hepatocellular carcinoma. Today, there is no approved treatment for NASH due to, at least in part, the lack of preclinical models recapitulating features of human disease. Here, we report the development of a dietary model of NASH in the Göttingen minipig. Methods: First, we performed a longitudinal characterization of diet-induced NASH and fibrosis using biochemical, histological, and transcriptional analyses. We then evaluated the pharmacological response to Obeticholic acid (OCA) treatment for 8 weeks at 2.5mg/kg/d, a dose matching its active clinical exposure. Results: Serial histological examinations revealed a rapid installation of NASH driven by massive steatosis and inflammation, including evidence of ballooning. Furthermore, we found the progressive development of both perisinusoidal and portal fibrosis reaching fibrotic septa after 6 months of diet. Histological changes were mechanistically supported by well-defined gene signatures identified by RNA Seq analysis. While treatment with OCA was well tolerated throughout the study, it did not improve liver dysfunction nor NASH progression. By contrast, OCA treatment resulted in a significant reduction in diet-induced fibrosis in this model. Conclusions: These results, taken together, indicate that the diet-induced NASH in the Göttingen minipig recapitulates most of the features of human NASH and may be a model with improved translational value to prioritize drug candidates toward clinical development.

RESUMO

Background: The FibroScan-AST (FAST) score was recently described to detect patients with nonalcoholic steatohepatitis (NASH) having elevated nonalcoholic fatty liver disease (NAFLD) activity score (NAS ≥ 4) and significant fibrosis (≥ F2) on liver biopsy (NASH+ NAS ≥ 4 + F ≥ 2). Aim: The aim of this study was to validate the FAST score in Indian patients with NAFLD and to derive optimal cut-offs. Methods: Sixty patients with biopsy-proven NAFLD [men: 38 (63.3%), age 40 (32-52) years] with all parameters for assessing the FAST score within 3 months of liver histology were retrospectively analysed. Results: Histological NASH was present in 17 patients (28.3%), while 11 (18.3%) patients had NASH + NAS ≥ 4 + F ≥ 2. The area under the curve (AUROC) of the FAST score for discriminating NASH + NAS ≥ 4 + F ≥ 2 was 0.81. Using cut-offs by Newsome et al, the rule-out cut-off (FAST: ≤ 0.35) had a negative predictive value (NPV) of 0.88 [sensitivity: 0.91, specificity: 0.14, negative likelihood ratio (LR): 0.64], while the rule-in cut-off (FAST: ≥ 0.67) had a positive predictive value (PPV) of 0.33 (sensitivity: 0.73, specificity: 0.67, positive LR: 2.22). Fifteen (25%) patients were correctly classified as per histology, while 28 (46.67%) patients fell in the grey zone. On recalculating the optimal cut-offs for our patients, the rule-out cut-off (FAST: ≤ 0.55) had an NPV of 0.95 (sensitivity: 0.90, specificity: 0.45, negative LR: 0.21), while the optimal rule-in cut-off (FAST: ≥ 0.78) had a PPV of 0.70 (sensitivity: 0.64, specificity 0.94, positive LR: 10.39). With these cut-offs, 27 (45%) patients fell in the grey zone and 29 (48.3%) were correctly classified as per histology, performing better than the cut-offs by Newsome et al (P < 0.001). Conclusion: The FAST score demonstrates good AUROC for detecting NASH with significant fibrosis and inflammation on histology. Cut-offs should be recalibrated based on prevalence of disease. Lay summary: India has a high burden of NAFLD with an estimated 25 million patients at potential risk for significant liver disease. Liver biopsy remains the gold standard for diagnosing NASH, although its application in routine clinical practice is limited. Noninvasive tests for the simultaneous detection of steatosis, inflammation and fibrosis are thus the need of the hour. The FAST score has been recently suggested for the noninvasive detection of NASH with significant fibrosis (≥ F2) and inflammation (NAS ≥ 4) on liver biopsy. We validated the utility of the FAST score for detecting NASH with significant fibrosis and inflammation on liver biopsy in Indian patients with NAFLD. This noninvasive, easy-to-use and nonproprietary FAST score can correctly classify disease severity in more than 50% patients. However, our results suggest that cut-offs should be recalibrated based on the anticipated prevalence of NASH + NAS ≥ 4 + F ≥ 2 in the given population.

RESUMO

Background & aims: There is no "gold standard" tool for the assessment of frailty in cirrhosis. This study compares Liver Frailty Index (LFI), Short Physical Performance Battery (SPPB), Fried Frailty Criteria (FFC), and Clinical Frailty Scale (CFS) for frailty assessment and ascertains its impact on predicting mortality and hospitalizations in a cohort of outpatients with cirrhosis. Methods: 116 patients were enrolled in this prospective observational cohort study. Frailty assessment was done using LFI, SPPB, FFC, and CFS. All patients were followed up for 6 months. The primary outcome was the first of either all-cause unplanned hospitalization or all-cause mortality occurring within 6 months of the study period. Results: 100 (86.2%) males and 16 (13.8%) females with a mean age of 50.2 (48.4-51.9, 95% CI) years were included. The most common cause of cirrhosis was alcoholic liver disease (47.4%) followed by hepatitis C (12.9%) and Nonalcoholic steatohepatitis (NASH) (10.3%). There was no significant difference in prevalence of frailty based on LFI (43.1%), FFC (36.2%), CFS (44%), and SPPB (47.4%) (P > 0.05). Frail patients had worse outcomes compared to the Not frail group. At 6 months, the mortality rate in Frail patients was 42% versus 1.5% for the Not frail; hospitalization in Frail patients occurred in 92% versus 6% in the Not frail. On multivariable analysis, independent predictors of mortality were Frailty [OR 14 (1.4-54.2)], alcohol-related cirrhosis [OR 4.2 (1.1-16.3)], Child-Turcotte-Pugh (CTP) [OR 2.1 (1.4-2.9)] and Chronic liver disease questionnaire (CLDQ) [OR 0.1 (0.1-0.4)] scores. Conclusions: LFI, SPPB, FFC, and CFS are comparable in frailty assessment in patients with cirrhosis. Importantly, comparability of the commonly used scores for frailty assessment and prediction of hospitalization and mortality allows flexibility for clinical application.

RESUMO

Background: Spontaneous rupture of hepatocellular carcinoma (HCC) is a potentially fatal complication and the third leading cause of death in patients with HCC after tumor progression and liver failure. Previous studies suggested that improved HCC surveillance has decreased the incidence of rupture. This study aims to characterize patients with ruptured HCC over time and identify predictors of rupture. Methods: We retrospectively reviewed a prospectively collected database of 1451 HCC patients to identify cases with rupture and predictors of rupture. Data were divided into three 9-year eras to compare and trend patient/tumor characteristics and rupture. Results: Fifty-seven patients (3.9%) presented with spontaneous HCC rupture and the following characteristics: mean age 62.6 years, 73.7% males, 41% cirrhosis, and mean tumor size of 8.0 cm. On multivariate analyses, predictors of rupture included obesity, tumor >5 cm, and single tumors, whereas the presence of cirrhosis was a negative predictor for rupture.Across three eras, there were changes in disease etiology and decreases in tumor size, and more HCCs were found with surveillance. However, more patients were noncirrhotic, and the incidence of spontaneous rupture was unchanged over time. Conclusion: Despite improved early detection of HCC over time, the incidence of rupture has been unchanged. The persistent incidence of rupture may possibly be attributed to increasing proportion of fatty liver-related HCC patients who lack traditional risk factors for surveillance and may not have cirrhosis. Better identification of fatty liver disease and determining which patients need HCC surveillance may be needed in the future to prevent spontaneous rupture.

RESUMO

Background and aims: Acute-on-chronic liver failure (ACLF) is associated with high short-term mortality. There is a paucity of data about the spectrum of neuroimaging abnormalities in the brain in ACLF patients. The present study was aimed to study the prevalence of cerebral edema and other parenchymal changes in MR imaging of the brain in patients with ACLF. Methods: In this prospective observational study, MR imaging was done in patients with ACLF (n = 41), and findings were compared with age and sex-matched patients with acute decompensation (AD) (n = 13) and those with cirrhosis but without any decompensation at recruitment (n = 21). Results: Forty-one patients with ACLF (24.4% Grade 1 and Grade 2, 51.2% Grade 3) with 14 (34.1%) having cerebral failure were included in the study. T2-weighted (T2W) diffuse white matter hyperintensities (WMHs) and focal WMHs were seen in 17 (41.4%) and 7 (17%) patients, respectively. T1W basal ganglia hyperintensities in 20 (48.7%), cerebral microbleeds (CMBs) in 6 (14.6%), and 2 (4.8%) patients had cerebral edema. In patients with AD, T2W diffuse WMHs were seen in 3 (23%), T2W focal WMHs in 3 (23%) patients. None of the patients with AD had cerebral edema or CMBs. In compensated cirrhosis patients, T2W diffuse WMHs were present in 7 (33.3%), T2W focal WMHs in 5 (23.8%), while 3 (14.2%) patients had CMBs. T1 weighted hyperintensities in basal ganglia were more common in AD [9 (69.2%)] and compensated cirrhosis [15 (71.4%)] as compared to ACLF patients [20 (48.7%)], P = 0.174. The survival time of 30 and 90 days for patients with diffuse T2W WMHs was significantly lesser than patients without T2W WMHs (P = 0.007). Conclusion: Cerebral edema is uncommon in ACLF patients, and T2-weighted diffuse white matter hyperintensities may be associated with worse outcomes. However, due to the limited scope of the present study, the same needs to be explored further in larger cohorts.

RESUMO

Although stomal and parastomal varices are uncommon causes of variceal bleeding, the mortality rate might be as high as 40%. Timely intervention is essential for the management of these ectopic bleeding varices. Due to the rarity of such varices, no standard treatment guideline is available. We present three cases of bleeding stomal varices managed with an endovascular approach, one through percutaneous transhepatic and the other two through transjugular intrahepatic portosystemic shunt approach.

RESUMO

The management of diabetes in cirrhosis and liver transplantation can be challenging. There is difficulty in diagnosis and monitoring of diabetes as fasting blood sugar values are low and glycosylated hemoglobin may not be a reliable marker. The challenges in the management of diabetes in cirrhosis include the likelihood of cognitive impairment, risk of hypoglycemia, altered drug metabolism, frequent renal dysfunction, risk of lactic acidosis, and associated malnutrition and sarcopenia. Moreover, calorie restriction and an attempt to lose weight in obese diabetics may be associated with a worsening of sarcopenia. Many commonly used antidiabetic drugs may be unsafe or be associated with a high risk of hypoglycemia in cirrhotics. Post-transplant diabetes is common and may be contributed by immunosuppressive medication. There is inadequate clinical data on the use of antidiabetic drugs in cirrhosis, and the management of diabetes in cirrhosis is hampered by the lack of guidelines focusing on this issue. The current review aims at addressing the practical management of diabetes by a hepatologist.
