Association between diabetes mellitus and hepatic encephalopathy in patients with cirrhosis

Other causes of neurocognitive impairment than covert hepatic encephalopathy (CHE) are very frequent, either alone or associated with CHE, in cirrhotic patients with cognitive complaints

BACKGROUND/AIMS

Although it is well admitted that cirrhotic patients display various causes of neurocognitive impairment (NI) hampering the diagnosis of covert hepatic encephalopathy (CHE), those are almost never investigated per se. The aims of this study were, in cirrhotic patients displaying cognitive complaints explored by a complete multimodal work-up, to assess: (1) the prevalence of CHE and/or that of other causes of NI and (2) their outcomes, according to the cause of NI.

METHODS

Prospective cohort of cirrhotic patients referred in a dedicated clinic because of cognitive complaints. Work-up included a complete neuropsychological assessment, electroencephalogram (EEG) and brain magnetic resonance imaging with spectroscopy. The diagnosis of CHE was made by an adjudication committee involving the physicians/neuropsychologist.

RESULTS

One hundred and twenty-three patients were included (alcohol/MASLD/virus in 63/53/14%, MELD = 11). Sixty-six per cent of them were diagnosed with CHE; among them, 73% exhibited also other causes of NI, mainly cerebrovascular diseases/psychiatric. Among patients without CHE, 48% and 59% displayed pathological Psychometric Hepatic Encephalopathy Score and animal naming test, respectively. Clinical improvement was observed in 77% of the patients re-evaluated after specific management. CHE, but not the other causes of NI, was independently associated with OHE occurrence.

CONCLUSION

Other causes of NI than CHE are frequent in patients with cirrhosis, and not ruled-out by the classical tests dedicated to CHE. Prognosis was influenced by the cause of NI. The management of patients even without CHE led to clinical improvement, underlining the need for a multifaceted approach of cirrhotic patients with cognitive complaints.

Rifaximin plus lactulose versus lactulose alone for reducing the risk of HE recurrence

BACKGROUND

The aim was to examine rifaximin plus lactulose efficacy in patients with cirrhosis at a risk of developing overt HE who were stratified by important baseline characteristics such as comorbid ascites or diabetes.

METHODS

Pooled post hoc subgroup analysis of adults receiving rifaximin 550 mg twice daily plus lactulose or lactulose alone for 6 months in a phase 3 randomized, double-blind trial and a phase 4 open-label trial was conducted.

RESULTS AND CONCLUSION

Rifaximin plus lactulose was more efficacious than lactulose alone for reducing the risk of overt HE recurrence and HE-related hospitalization in adults grouped by select baseline disease characteristics.

Higher scores in the Clinical Frailty Scale are associated with covert and overt hepatic encephalopathy in patients with cirrhosis

BACKGROUND

Frailty increases the vulnerability to internal and external stressors and may therefore be an indicator of a higher frequency of cirrhosis complications. We aimed to investigate the association of the Clinical Frailty Scale (CFS) with covert (CHE) and overt HE (OHE) development in patients with cirrhosis.

METHODS

This study analyzed data of 228 patients with cirrhosis. Frailty was assessed using CFS. Patients were examined for the presence of CHE (using PHES) at study inclusion and followed for OHE.

RESULTS

Median CFS was 3 and 26 (11 %) patients were at least pre-frail (CFS>3). In multivariable logistic regression analysis in patients without a history of OHE (n = 195), a higher CFS was associated with the presence of CHE at baseline (OR 1.6, p = 0.039). During follow-up, 42 (18 %) patients developed an episode of OHE. In multivariable competing risk regression analyses, a higher CFS was independently associated with the development of an OHE episode in the total cohort (sHR 1.97, p < 0.001) and in the subcohort of patients without a history of OHE (sHR 1.88, p = 0.008).

CONCLUSION

CFS appears to be a reliable tool to identify patients at higher risk of HE in whom intensified monitoring and treatment may be justified.

Hepatic Encephalopathy: Clinical Manifestations

Hepatic encephalopathy (HE) can occur as a complication of chronic liver disease as well as acute liver failure. HE is associated with significantly increased morbidity and worse patient outcomes. The clinical manifestation of HE ranges from early less-severe presentations that may only be accurately detected on dedicated psychomotor diagnostic testing to overt alterations in cognition and mental status to the most severe form of coma. Greater awareness of the clinical manifestations of HE across the spectrum of symptom severity is critical for early identification and timely initiation of appropriate therapy to improve patient outcomes.

Prediction of mortality and overt hepatic encephalopathy undergoing transjugular intrahepatic portosystemic shunt: a retrospective cohort study

PURPOSE

Data on medium- and long-term efficacy and safety of Transjugular intrahepatic portosystemic shunt (TIPS) using Viatorr stents in Chinese patients are limited. This study aimed to evaluate the 5-year mortality and the incidence of overt hepatic encephalopathy (OHE) after Viatorr stent insertion, and construct a model to predict post-TIPS OHE preoperatively.

METHODS

One hundred thirty-two patients undergoing Viatorr stent insertion in our institution between August 2016 and December 2019 were included, and randomly divided into training and validation cohort at a 70/30 ratio. Patients were followed up until death or the end date of follow-up (December 31st, 2021). The primary end point was all-cause mortality, and the secondary end points were OHE, variceal rebleeding, recurrent ascites and shunt dysfunction.

RESULTS

The 1-, 2-, 3-, 4- and 5-year cumulative survival rates were 92.4%, 87.9%, 85.3%, 80.2% and 80.2%, respectively. Post-TIPS OHE and Child-Pugh grade were independent prognostic factors. The rates of variceal rebleeding, recurrent ascites, shunt dysfunction and post-TIPS OHE were 9.1%, 14.3%, 5.3% and 28.0%, respectively. The variables of nomogram predicting post-TIPS OHE included age, diabetes and ascites grade. The area under time-dependent receiver operation characteristic (ROC) curve (AUC) in training and validation cohort were 0.806 and 0.751, respectively. The decision curve analysis (DCA) showed good net benefit both in training and validation cohort.

CONCLUSION

Post-TIPS OHE and Child-Pugh grade are independent prognostic factors for early mortality in cirrhosis patients, thus we construct a simple and convenient prediction model for post-TIPS OHE to identify high-risk patients preoperatively.

Reduced mortality and morbidity associated with metformin and SGLT2 inhibitor therapy in patients with type 2 diabetes mellitus and cirrhosis

INTRODUCTION

Evidence for dual antidiabetic therapy in type 2 diabetes mellitus patients with cirrhosis is limited. This study compared 5-year mortality, composite hepatic decompensation risk, and hepatocellular carcinoma occurrence in patients with diabetes and cirrhosis who were either on metformin monotherapy or on dual metformin and sodium-glucose co-transporter-2 inhibitor (SGLT2-I) therapy.

METHODS

This retrospective study used the TriNetX Research Network to identify propensity score-matched patients treated with either metformin or dual metformin and SGLT2-I therapy. Our outcomes were all-cause mortality, a composite of hepatic decompensation events, and hepatocellular carcinoma (HCC) occurrence over 5 years. We estimated hazard ratios within each cohort with 95% confidence intervals (CI) and Kaplan-Meier estimates for time-to-event distributions with Log-rank tests. We were able to stratify our cohorts by age, sex, race, and ethnicity. We further investigated a subset of diabetic patients with cirrhosis due to MASH.

RESULTS

In our propensity score-matched cohorts of type 2 diabetes patients with cirrhosis, those on dual metformin and SGLT2-I therapy had decreased risk for mortality (HR 0.57, 95%CI 0.41-0.81), reduced composite risk of becoming decompensated (HR 0.63, 95%CI 0.43-0.93) and less than half the risk for developing HCC (HR 0.43, 95%CI 0.21-0.88) compared to those on mono metformin therapy. We did not find a difference between mono or dual therapy treatment for mortality, decompensation, or HCC risks in the subset of patients with MASH cirrhosis.

CONCLUSION

Dual metformin and SGLT2-I treatment in type 2 diabetes patients with cirrhosis are associated with improved mortality and hepatic complications.

Keeping an eye on the nutrition: The importance of nutrition management on cardiometabolic risk factors in cirrhotic patients

Chronic liver diseases, especially cirrhosis, are associated with significant morbidity and mortality. Besides predisposing to chronic liver disease per se, diabetes, hypertension, and dyslipidemia worsen the prognosis of patients with cirrhosis induced by other causes. There is no standard of care in the management of these factors in patients with cirrhosis. Also, in particular, it is not known whether nutritional interventions in the modification of cardiometabolic factors can improve the course of cirrhosis or not. This narrative review aimed to investigate the clinical significance of diabetes, hypertension, and dyslipidemia and appropriate nutritional interventions in cirrhotic patients. A comprehensive literature search of the published data was performed in regard to the association of cirrhosis with cardiometabolic factors and the management of cirrhosis and its complications. There is limited evidence on the association of cirrhosis with cardiometabolic risk factors. Cirrhotic cardiometabolic abnormalities are associated with an increased risk of complications, such that the coexistence of diabetes, hypertension, and dyslipidemia increases the risk of clinical decompensation in cirrhosis. Dietary management of cirrhotic patients with risk factors such as diabetes, hypertension, or dyslipidemia does not seem to be considerably different from non-cirrhotic patients.

Gallic acid and metformin co-administration reduce oxidative stress, apoptosis and inflammation via Fas/caspase-3 and NF-κB signaling pathways in thioacetamide-induced acute hepatic encephalopathy in rats

BACKGROUND

Hepatic encephalopathy (HE) is a consequence of chronic or acute liver diseases. This study evaluates the combined effect of gallic acid (GA), and metformin (Met) on the liver and brain damage associated with HE.

METHODS

Acute HE was induced by a single dose of thioacetamide (TAA) (300 mg/kg) as an I.P. injection. Treated groups received GA group (100 mg/kg/day, p.o), Met (200 mg/kg/day, p.o), or their combination for 25 consecutive days before TAA injection.

RESULTS

The administration of TAA induced various biochemical and histopathological alterations. In contrast, treatment with GA either alone or combined with Met resulted in improved liver functions by the significant reduction in serum ALT, AST, and ALP activities, and ammonia levels. Inflammatory mediators; TNF-α, IL-6, and NFkβ levels were decreased by these treatments as well as apoptotic cascade via down-regulation of FAS and caspase-3 (CASP-3) expression in hepatic tissues. Furthermore, GA and Met either alone or combined protected the liver and brain tissues from damage by increased glutathione concentration while decreasing malondialdehyde. In addition, it was accompanied by the improvement of the brain neurotransmitter profile via the restoration of norepinephrine, dopamine, and serotonin levels. Based on our data, this is the first study to report a novel combined hepatoprotective and cognitive enhancing effect of GA and Met against TAA-induced acute liver and brain injury.

CONCLUSION

GA and Met combination resulted in a prominent improvement in HE complications, relative to monotherapy. Both agents potentiated the antioxidant, anti-inflammatory, and anti-apoptotic effects of each other.

Diabetes and cirrhosis: Current concepts on diagnosis and management

Type 2 diabetes mellitus is often associated with cirrhosis as comorbidities, acute illness, medications, and other conditions profoundly alter glucose metabolism. Both conditions are closely related in NAFLD, the leading cause of chronic liver disease, and given its rising burden worldwide, management of type 2 diabetes mellitus in cirrhosis will be an increasingly common dilemma. Having diabetes increases cirrhosis-related complications, including HCC as well as overall mortality. In the absence of effective treatments for cirrhosis, patients with type 2 diabetes mellitus should be systematically screened as early as possible for NAFLD-related fibrosis/cirrhosis using noninvasive tools, starting with a FIB-4 index followed by transient elastography, if available. In people with cirrhosis, an early diagnosis of diabetes is critical for an optimal management strategy (ie, nutritional goals, and glycemic targets). Diagnosis of diabetes may be missed if based on A1C in patients with cirrhosis and impaired liver function (Child-Pugh B-C) as anemia may turn the test unreliable. Clinicians must also become aware of their high risk of hypoglycemia, especially in decompensated cirrhosis where insulin is the only therapy. Care should be within multidisciplinary teams (nutritionists, obesity management teams, endocrinologists, hepatologists, and others) and take advantage of novel glucose-monitoring devices. Clinicians should become familiar with the safety and efficacy of diabetes medications for patients with advanced fibrosis and compensated cirrhosis. Management is conditioned by whether the patient has either compensated or decompensated cirrhosis. This review gives an update on the complex relationship between cirrhosis and type 2 diabetes mellitus, with a focus on its diagnosis and treatment, and highlights knowledge gaps and future directions.

[Mobile everyday-life digital technologies for the prevention of Alzheimer's dementia: cognitive health and cognitive safety]

It is generally accepted that the treatment of Alzheimer's disease should be flanked by preventive measures for risk reduction in order to maintain cognitive functions for as long as possible; however, the research and development of treatment concepts are both faced with challenges. The preventive risk reduction necessitates a high level of coordination of neurology and psychiatry with other disciplines. Also, patients must develop a high level of health competence and summon up self-motivation and adherence. This concept article deals with the question of how mobile everyday-life digital technologies can help to address these challenges. The core prerequisite is the interdisciplinary coordinated structuring of prevention with the focus on cognitive health and cognitive safety. Cognitive health relates to a reduction of risk factors associated with lifestyle. Cognitive safety concerns the avoidance of iatrogenic side effects on cognitive functions. Digital technologies that are relevant in this context are mobile apps based on smartphones or tablets for everyday-life and high-frequency recording of cognitive functions, apps that can coach the implementation of lifestyle changes as companion technologies, apps that can assist in the reduction of iatrogenic risks and those that can improve the health competence of patients and relatives. The state of development of such medical products is at different stages of progress. Therefore, this concept article does not provide a review of existing products but rather deals with the fundamental interplay of potential solutions in the prevention of Alzheimer dementia in the areas of cognitive health and cognitive safety.

Diabetes mellitus - risk factor and potential future target for hepatic encephalopathy in patients with liver cirrhosis?

Hepatic encephalopathy (HE) is one of the major complications of cirrhosis, and its presence is associated with poor survival. Several risk factors for HE are well established, including age, history of HE, portosystemic shunts, or poorer liver function. In recent years, diabetes mellitus (DM) has emerged as another potential risk factor for the development of HE. This may be important for many patients, as the incidence of type 2 DM (T2DM) is increasing worldwide and, consequently, the incidence of NAFLD-related cirrhosis is rising simultaneously. In addition, DM is a critical factor in the progression of other liver diseases, such as alcohol-related liver disease. Thus, the number of patients with cirrhosis and comorbid T2DM will also increase. To date, the prevalence of DM already ranges between 22 - 40% in patients with cirrhosis. DM-associated factors that may influence the risk of HE include systemic inflammation, insulin resistance with increased muscle protein breakdown as well as autonomic dysfunction with prolonged intestinal transit time and small intestinal bacterial overgrowth. Currently, the evidence for an association between DM and both minimal and overt HE is weak and it seems likely that only poor glycemic control has an impact on HE risk. In addition, there are some early signs indicating that DM may impair the response of patients with HE to pharmacological therapies such as rifaximin. Thus, improvements in the management of glycemic control may be a candidate future target to reduce the risk of HE. In this concise review, we summarize the current evidence on the association between DM and HE and its potential future implications.

Hepatogenous diabetes: Knowledge, evidence, and skepticism

The diabetogenic potential of liver cirrhosis (LC) has been known for a long time, and the name "hepatogenous diabetes" (HD) was coined in 1906 to define the condition. Diabetes mellitus (DM) that develops as a consequence of LC is referred to as HD. In patients with LC, the prevalence rates of HD have been reported to vary from 21% to 57%. The pathophysiological basis of HD seems to involve insulin resistance (IR) and pancreatic β-cell dysfunction. The neurohormonal changes, endotoxemia, and chronic inflammation of LC initially create IR; however, the toxic effects eventually lead to β-cell dysfunction, which marks the transition from impaired glucose tolerance to HD. In addition, a number of factors, including sarcopenia, sarcopenic obesity, gut dysbiosis, and hyperammonemia, have recently been linked to impaired glucose metabolism in LC. DM is associated with complications and poor outcomes in patients with LC, although the individual impact of each type 2 DM and HD is unknown due to a lack of categorization of diabetes in most published research. In fact, there is much skepticism within scientific organizations over the recognition of HD as a separate disease and a consequence of LC. Currently, T2DM and HD are being treated in a similar manner although no standardized guidelines are available. The different pathophysiological basis of HD may have an impact on treatment options. This review article discusses the existence of HD as a distinct entity with high prevalence rates, a strong pathophysiological basis, clinical and therapeutic implications, as well as widespread skepticism and knowledge gaps.

Hepatic encephalopathy

Hepatic encephalopathy (HE) is a prognostically relevant neuropsychiatric syndrome that occurs in the course of acute or chronic liver disease. Besides ascites and variceal bleeding, it is the most serious complication of decompensated liver cirrhosis. Ammonia and inflammation are major triggers for the appearance of HE, which in patients with liver cirrhosis involves pathophysiologically low-grade cerebral oedema with oxidative/nitrosative stress, inflammation and disturbances of oscillatory networks in the brain. Severity classification and diagnostic approaches regarding mild forms of HE are still a matter of debate. Current medical treatment predominantly involves lactulose and rifaximin following rigorous treatment of so-called known HE precipitating factors. New treatments based on an improved pathophysiological understanding are emerging.

Clinical implications of hepatic structure and function evaluation based on vibration-controlled transient elastography and liver maximum function capacity test in patients with nonalcoholic fatty liver disease

BACKGROUND AND AIMS

Transient elastography [vibration-controlled transient elastography (VCTE)] noninvasively guides risk stratification in patients with nonalcoholic fatty liver disease (NAFLD). Patients with nonalcoholic steatohepatitis (NASH) and fibrosis can be identified using the FAST-score. The liver maximum function test (LiMAx) could be helpful in more precise risk stratification. This pilot study evaluated VCTE, FAST-score, and LiMAx in NAFLD patients.

METHODS

NAFLD patients prospectively underwent VCTE and LiMAx. The cutoffs for high fibrosis risk were 9.3/9.6 kPa (M/XL-probe) and 331 dB/m for steatosis. A FAST-score greater than 0.67 was used to identify patients with NASH and LiMAx values below 315 μg/kg/h for impaired liver function.

RESULTS

In total, 57 NAFLD patients (BMI 32 ± 6 kg/m2; 60% diabetes) were included. High risk for fibrosis and steatosis was observed in 26/57 and 28/57 cases, respectively. Overall, 19/57 patients presented impaired liver function. However, 14/26 of patients with a high risk for fibrosis had impaired liver function compared to 5/31 of those without (P = 0.0026). Similarly, 12/18 patients at high risk for NASH had impaired liver function compared to 7/39 without (P < 0.001). The subgroup with diabetes had a liver stiffness a factor of 1.8 higher, FAST-score was 0.13 higher and LiMAx values were 66 μg/kg/h lower compared to nondiabetics.

CONCLUSION

There is a significant correlation between the functional liver capacity (LiMAx) and the structural liver assessment by VCTE. In cases with high liver stiffness or FAST-score, low LiMAx results may identify NAFLD patients at risk for disease progression and reduce the risk of false-positive categorization.

Validation of EncephalApp_Stroop as screening tool for the detection of minimal hepatic encephalopathy in German patients with liver cirrhosis

BACKGROUND

In contrast to overt hepatic encephalopathy (OHE), the diagnosis of minimal HE (MHE) is challenging in patients with cirrhosis requiring elaborate, specialized testing. The EncephalApp_Stroop is a smartphone-based application established as screening tool for the diagnosis of MHE but has not yet been validated in a German cohort and country specific cut-offs are currently missing.

METHODS

93 patients with cirrhosis were enroled into this study. Psychometric hepatic encephalopathy score (PHES) was used to detect MHE, and a subset of the patients was tested with critical flicker frequency (CFF). All patients underwent testing with EncephalApp_Stroop. Cut-off thresholds for EncephalApp_Stroop were calculated according to Youden's Index and a separate cut-off was determined with focus on sensitivity.

RESULTS

24 (26%) patients had MHE according to PHES. EncephalApp_Stroop had a strong correlation with PHES (r=-0.76, p<0.001), while there was only a modest correlation with CFF (r=-0.51, <0.001). On time as well as on+off time discriminated best between patients with and without MHE with AUROCS of 0.87 for both measures. According to Youden's index, a cut-off of >224.7 s (sec) (on+off time) discriminated best between patients with and without MHE with a sensitivity of 71% and a specificity of 88%. The adjusted cut-off value for on+off time with focus on sensitivity (sensitivity:specificity weighed 2:1) was 185.1 s, yielding an optimized sensitivity of 92% and a negative predictive value of 96%. By using this cut-off as a pre-screening test in a stepwise diagnosis algorithm, elaborate testing with PHES could have been avoided in 49% of all patients.

CONCLUSION

EncephalApp_Stroop may be useful in a stepwise diagnosis algorithm or even as a stand-alone screening tool to detect MHE in German patients with cirrhosis.

Clinical implications of diabetes in chronic liver disease: Diagnosis, outcomes and management, current and future perspectives

Diabetes mellitus (DM) is common in liver cirrhosis (LC). The pathophysiological association is bidirectional. DM is a risk factor of LC and LC is a diabetogenic condition. In the recent years, research on different aspects of the association DM and LC has been intensified. Nevertheless, it has been insufficient and still exist many gaps. The aims of this review are: (1) To discuss the latest understandings of the association of DM and LC in order to identify the strategies of early diagnosis; (2) To evaluate the impact of DM on outcomes of LC patients; and (3) To select the most adequate management benefiting the two conditions. Literature searches were conducted using PubMed, Ovid and Scopus engines for DM and LC, diagnosis, outcomes and management. The authors also provided insight from their own published experience. Based on the published studies, two types of DM associated with LC have emerged: Type 2 DM (T2DM) and hepatogenous diabetes (HD). High-quality evidences have determined that T2DM or HD significantly increase complications and death pre and post-liver transplantation. HD has been poorly studied and has not been recognized as a complication of LC. The management of DM in LC patients continues to be difficult and should be based on drug pharmacokinetics and the degree of liver failure. In conclusion, the clinical impact of DM in outcomes of LC patients has been the most studied item recently. Nevertheless many gaps still exist particularly in the management. These most important gaps were highlighted in order to propose future lines for research.

Cognitive Impairment and Cirrhosis in Older Patients: A Systematic Review

Prevalence of cirrhosis and hepatic encephalopathy (HE) in older patients receiving care in long-term care settings is unknown. This systematic review aimed to identify potential factors associated with HE and cognitive impairment in older patients with cirrhosis. A PubMed search of English-language articles published between January 1, 2000, and November 3, 2021, was conducted to identify studies in adults with cirrhosis relevant to cognitive impairment and/or HE (e.g., fall, frailty, and sarcopenia). Of 2,879 English-language publications, 24 were included. In patients with cirrhosis, falls were increased in the presence of HE and were associated with increased injury risk. Frailty was associated with HE development and cognitive impairment in patients with cirrhosis. Further, cognitive impairment and frailty were predictive of HE-related hospitalizations. Sarcopenia increased the risk of developing HE. Furthermore, specific medications increased the risk of developing HE. Risk reduction and management of patients with HE are critical to prevent negative outcomes.

Association of Type 2 Diabetes and Hepatic Encephalopathy in Chronic Liver Disease Patients

Background

Hepatic encephalopathy (HE) is an important complication of hepatic cirrhosis and is an independent predictor of mortality in patients with cirrhosis. The prevalence of type 2 diabetes continues to increase at an alarming rate around the world, with even more people being affected by prediabetes. Diabetes leads to increased gastric transit and orocecal time, increased glutamase activity, and intestinal bacterial overgrowth, which may increase intestinal ammonia production. Thus, we speculated that diabetes mellitus (DM) might predispose cirrhotic patients to development and/or exacerbation of HE. The main purpose of this study is to determine the association of DM with severe HE in patients with chronic liver disease (CLD).

Methods

This case-control study (122 cases and 122 controls) was conducted for 6 months on patients who fulfilled the inclusion criteria and were selected from the Medical department, Abbasi Shaheed Hospital, Karachi, after taking informed consent. Demographic data were presented as simple descriptive statistics giving mean and standard deviation and qualitative variables were presented as frequency and percentages. Chi-square was applied and the odds ratio (OR) was calculated taking a p-value of ≤ 0.05 as statistically significant.

Results

Out of a total of 244 patients, 122 patients had CLD with DM (case group) and 122 participants had CLD without DM (control group). The mean and standard deviation of age in the case and control groups in our study was 43.29±3.79 and 45.49±5.40. The mean and standard deviation of the duration of disease in the case and control groups in our study was 3.18±1.22 and 3.72±1.36. Males were 53 (43.44%) and 56 (45.10%) in the case and control groups, whereas females were 69 (56.56%) and 66 (54.10%) in the case and control groups, respectively. Out of 122 patients in the case group, 73 (59.84%) and 49 (40.16%) patients developed and did not develop severe HE, respectively. Out of 122 patients in the control group, 50 (40.98%) and 72 (59.02%) patients developed and did not develop severe HE, respectively. Binary logistic regression analysis showed an association of severe HE with DM (p-value: 0.93, OR: 1.033, 95% CI: 0.586-1.599).

Conclusion

This study demonstrates that HE is a common occurrence in CLD patients. There was not a direct relationship of DM with the severity of HE was observed. However, further research with larger sample size and involving a multicenter setting is warranted.

Risk factors for poorer health literacy in patients with liver cirrhosis

BACKGROUND

Health literacy is a concept that refers to patients' ability to manage their disease and the health system's ability to guarantee access to services. There is evidence that health literacy impacts the health outcomes of patients with chronic diseases, but detailed information on this topic in patients with liver cirrhosis is scarce. It was the aim of this study to identify risk factors for poorer health literacy in patients with liver cirrhosis.

METHODS

89 patients with liver cirrhosis were enrolled in this study and health literacy was measured using the Health Literacy Questionnaire (HLQ). Covert hepatic encephalopathy (CHE) was diagnosed clinically according to the West-Haven Criteria (HE grade 1) and the PHES (minimal HE). Depressive symptoms were assessed using the Hamilton Depression Rating Scale (HDRS). Based on the nine subscales of the HLQ, risk factors for poor health literacy were identified using linear regression models.

RESULTS

Normalized HLQ scores ranged between 65-76%, while appraisal of health information had lowest score (65%) and ability to actively engage with healthcare providers had highest score (76%). Multivariable regression analyses revealed an association of poorer health literacy and liver function as determined by MELD score and complications of liver cirrhosis such as a history of ascites or CHE. Additionally, we identified modifiable or preventable factors such as depressive symptoms, a history of falls, and active smoking as risk factors for poorer health literacy.

CONCLUSION

Multiple factors seem to impact on health literacy in patients with liver cirrhosis. Addressing modifiable and preventable factors may improve health literacy.

Type 2 diabetes mellitus increases liver transplant-free mortality in patients with cirrhosis: A systematic review and meta-analysis

BACKGROUND

The impact of type 2 diabetes mellitus (T2DM) on the prognosis and complications of liver cirrhosis is not fully clarified.

AIM

To clarify the mortality and related risk factors as well as complications in cirrhotic patients with T2DM.

METHODS

We searched PubMed, EMBASE, and the Cochrane Library from their inception to December 1, 2020 for cohort studies comparing liver transplant-free mortality, hepatocellular carcinoma (HCC), ascites, spontaneous bacterial peritonitis (SBP), variceal bleeding, and hepatic encephalopathy (HE) in cirrhotic patients with vs without T2DM. Odds ratios (ORs) were combined by using fixed-effects or random-effects models with RevMan software.

RESULTS

The database search generated a total of 17 cohort studies that met the inclusion criteria. Among these studies, eight reported the risk of mortality, and eight reported the risk of HCC. Three studies provided SBP rates, and two documented ascites rates. Four articles focused on HE rates, and three focused on variceal bleeding rates. Meta-analysis indicated that T2DM was significantly associated with an increased risk of liver transplant-free mortality [OR: 1.28, 95% confidence intervals (CI): 1.16-1.41, P < 0.0001] and HCC incidence (OR: 1.82, 95%CI: 1.32-2.51, P = 0.003). The risk of SBP was not significantly increased (OR: 1.16 95%CI: 0.86-1.57, P = 0.34). Additionally, T2DM did not significantly increase HE (OR: 1.31 95%CI: 0.97-1.77, P = 0.08), ascites (OR: 1.11 95%CI: 0.84-1.46, P = 0.46), and variceal bleeding (OR: 1.34, 95%CI: 0.99-1.82, P = 0.06).

CONCLUSION

The findings suggest that cirrhotic patients with T2DM have a poor prognosis and high risk of HCC. T2DM may not be associated with an increased risk of SBP, variceal bleeding, ascites, or HE in cirrhotic patients with T2DM.

Recompensation factors for patients with decompensated cirrhosis: a multicentre retrospective case-control study

OBJECTIVES

We aimed to evaluate recompensation factors among patients with decompensated cirrhosis.

DESIGN

A multicentre retrospective case-control study was conducted. Data were collected from and compared between groups of patients with recompensated and acute decompensated cirrhosis. Univariable and multivariable logistic regressions were used to select indicators associated with recompensation among patients with decompensated cirrhosis with different complications. A decision tree with 10-fold cross-validation was used to develop the model to identify patients with recompensation. We followed the transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) guideline for development and reporting of the new model.

SETTING

The study was conducted in six tertiary public hospitals in Chongqing, China.

PARTICIPANTS

This study included 3953 patients with decompensated cirrhosis.

RESULTS

In the total sample of included patients, there were 553 patients with recompensation and 3400 patients with acute decompensation, including 1158 patients with gastrointestinal bleeding, 1715 patients with a bacterial infection, 104 patients with hepatic encephalopathy and 423 patients with ascites. The most relevant indicator of recompensation selected by the decision tree model was albumin, with a threshold of 40 g/L. Total protein, haemoglobin, basophil percentage, alanine aminotransferase, neutrophil-to-lymphocyte ratio and diabetes were also selected to subsequently distinguish patients. The terminal nodes with a probability of recompensation was 0.89. The overall accuracy rate of the model was 0.92 (0.91-0.93), and it exhibited high specificity (86.9%) and sensitivity (92.6%).

CONCLUSIONS

The occurrence of recompensated cirrhosis could be identified by albumin, total protein, haemoglobin, basophil percentage, alanine aminotransferase, neutrophil-to-lymphocyte ratio and diabetes. These simple variables may help clinicians develop a treatment plan to encourage patients with decompensated cirrhosis to recompensate.

Association between Liver Cirrhosis and Diabetes Mellitus: A Review on Hepatic Outcomes

BACKGROUND

Liver cirrhosis (LC) is largely associated with diabetes mellitus (DM). More than 80% of patients with LC manifest glucose intolerance and about 30% have type 2 DM. A particular and yet unrecognized entity is hepatogenous diabetes (HD), defined as impaired glucose regulation caused by altered liver function following LC. Numerous studies have shown that DM could negatively influence liver-related outcomes.

AIM

We aimed to investigate whether patients with LC and DM are at higher risk for hepatic encephalopathy (HE), variceal hemorrhage (VH), infections and hepatocellular carcinoma (HCC). The impact of DM on liver transplant (LT) outcomes was also addressed.

METHODS

Literature search was performed in PubMed, Ovid, and Elsevier databases. Population-based observational studies reporting liver outcomes in patients with LC were included.

RESULTS

Diabetics are at higher risk for HE, including post-transjugular intrahepatic portosystemic shunt HE. DM also increases the risk of VH and contributes to elevated portal pressure and variceal re-bleeding, while uncontrolled DM is associated with increased risk of bacterial infections. DM also increases the risk of HCC and contributes to adverse LT outcomes.

CONCLUSIONS

Patients with DM and LC may benefit from close follow-up in order to reduce readmissions and mortality. Due to the heterogeneity of available research, prospective multicenter clinical trials are needed to further validate these findings.
