In patients with moderate-to-severe obstructive sleep apnea syndrome, 3 months of CPAP therapy lowers blood pressure and partially reverses metabolic abnormalities. (Funded by Pfizer; ClinicalTrials.gov number, NCT00694616.).

CLIF-SOFA criteria is better than APASL criteria to classify patients into ACLF based on their prognosis. CLIF-SOFA score is the best predictor of short-term mortality.

Minimal hepatic encephalopathy (MHE) is the mildest form of the spectrum of neurocognitive impairment in cirrhosis. It is a frequent occurrence in patients of cirrhosis and is detectable only by specialized neurocognitive testing. MHE is a clinically significant disorder which impairs daily functioning, driving performance, work capability and learning ability. It also predisposes to the development of overt hepatic encephalopathy, increased falls and increased mortality. This results in impaired quality of life for the patient as well as significant social and economic burden for health providers and care givers. Early detection and treatment of MHE with ammonia lowering therapy can reverse MHE and improve quality of life. ( J CLIN EXP HEPATOL 2015;5:S42-S48) H epatic encephalopathy (HE) is a neurocognitive disorder in which brain function is impaired and is associated with both acute and chronic liver dysfunction. 1 It is a major complication that develops in some form and at some stage in a majority of patients with liver cirrhosis. Minimal HE (MHE) is the mildest form of spectrum of HE which is characterized by subtle cognitive and psychomotor deficits in the absence of recognizable clinical symptoms of HE. 2 It occurs in patients with liver dysfunction and/or portosystemic shunts. In MHE, neurocognitive abnormalities primarily affect attention, speed of information processing, executive control, motor ability and coordination in an individual. 3 In 1970, Zeegen et al 4 first described this condition when they discovered that 38% of patients who had undergone portal decompression surgery scored abnormal in Reitan trail making test (number connection test). Eight years later, the term subclinical HE 5 was introduced to describe these patients. Since then, this condition was described under various names like early HE, latent HE, subclinical HE and finally minimal HE. The latest classification combines MHE and grade 1 HE into covert HE while higher grades are classified as overt HE, thus simplifying the clinical schema so that HE can be uniformly diagnosed. 6 Covert HE means that the mental defect is not detectable by the clinician using conventional testing and is not noticeable to the patient. However, it is significant because these patients usually have neuropsychiatric and neurophysiological abnormalities on advanced testing which are not enough to cause disorientation or asterixis. MHE is regarded as a preclinical stage of HE and ammonia and systemic inflammation plays an important role in its pathogenesis similar to HE. Ammonia lowering therapies were used in the treatment of MHE and found to be effective.MHE is clinically significant as it impairs daily functioning, health related quality of life (HRQOL) and driving skills, predicts the development of overt HE and is associated with poor survival. 7-11 Overt HE develops in >50% of MHE patients within three years. 10 These patients pose a significant burden to their care givers depending on the severity of cognitive dysfunction. 2,12 Considering all ...

Non-alcoholic fatty liver disease (NAFLD) is an important cause of liver disease worldwide with prevalence ranging from 10% to 30% in various countries. It has become an important cause of unexplained rise in transaminases, cryptogenic cirrhosis, and cryptogenic hepatocellular carcinoma. Pathogenesis is related to obesity, insulin resistance, oxidative stress, lipotoxicity, and resultant inflammation in the liver progressing to fibrosis. Pharmacological treatment in patients with NAFLD is still evolving and the treatment of these patients rests upon lifestyle modification with diet and exercise being the cornerstones of therapy. While there are many similarities between patients with NAFLD from Asia and the West, there are certain features which make the patients with NAFLD from Asia stand apart. This review highlights the data on NAFLD from Asia comparing it with the data from the West. ( J CLIN EXP HEPATOL 2012;2:122-134)

OBJECTIVES:Decreased magnetization transfer ratio (MTR) in the brain characterizes cerebral edema (CE) in patients with liver cirrhosis, but the role of treatment on its reversibility has not been studied in patients who have minimal hepatic encephalopathy (MHE). This study was carried to evaluate the reversibility of CE with lactulose and rifaximin treatment in patients with MHE and role of ammonia, pro-inflammatory interleukins (IL-1, IL-6) and tumor necrosis factor (TNF)-α in its pathogenesis.METHODS:Twenty-three patients with cirrhosis (14 with MHE, 9 without MHE (NMHE)) and 6 healthy controls underwent ammonia, IL-1, IL-6, TNF-α estimation, and MTR in frontal white matter (FWM), parietal white matter (PWM), internal capsule (IC), and basal ganglia (BG).RESULTS:Ammonia was significantly higher in the cirrhosis group compared with controls and in MHE compared with the NMHE group. Ammonia correlated positively with IL-1 and IL-6. MTRs in FWM, PWM, IC, and BG were significantly lower in the MHE group compared with controls and in PWM, IC, and BG compared with the NMHE group. MHE patients showed significant MTR increase in FWM, PWM, and IC with treatment. IL-6 and ammonia had significant negative and significant positive psychometric hepatic encephalopathy score (PHES) correlation with MTR in various regions.CONCLUSIONS:This study, for the first time, demonstrated the reversibility of low-grade CE with treatment in patients with MHE. Negative correlation between ammonia, IL-6 levels, and MTR and positive correlation between PHES and MTR in MHE patients suggests the role of inflammation and ammonia in the genesis of low-grade CE.

Non-invasive markers of fibrosis LSM, ELF and T relaxation time provide continuous surrogates for categorical histopathological staging of fibrosis which can be useful as markers of progression and regression of fibrosis on follow-up.

SOFC is a simpler and better method than the CANONIC grading system for predicting the in-hospital mortality in patients with ACLF defined as per APASL criteria.
