Noninvasive scores are poorly predictive of histological fibrosis in paediatric fatty liver disease.

OBJECTIVES: Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children. Roughly a quarter of paediatric patients with NAFLD develop nonalcoholic steatohepatitis and fibrosis. Here, we evaluated the diagnostic accuracy of previously published noninvasive fibrosis scores to predict liver fibrosis in a large European cohort of paediatric patients with NAFLD. METHODS: The 457 patients with biopsy-proven NAFLD from 10 specialized centers were included. We assessed diagnostic accuracy for the prediction of any (F ≥ 1), moderate (F ≥ 2) or advanced (F ≥ 3) fibrosis for the AST/platelet ratio (APRI), Fibrosis 4 score (FIB-4), paediatric NAFLD fibrosis score (PNFS) and paediatric NAFLD fibrosis index (PNFI). RESULTS: Patients covered the full spectrum of fibrosis (F0: n = 103; F1: n = 230; F2: n = 78; F3: n = 44; F4: n = 2). None of the scores were able to accurately distinguish the presence of any fibrosis from no fibrosis. For the detection of moderate fibrosis, area under the receiver operating characteristic curve (AUROC) were: APRI: 0.697, FIB-4: 0.663, PNFI: 0.515, PNFS: 0.665, while for detection of advanced fibrosis AUROCs were: APRI: 0.759, FIB-4: 0.611, PNFI: 0.521, PNFS: 0.712. Fibrosis scores showed no diagnostic benefit over using ALT ≤ 50/ > 50 IU/L as a cut-off. CONCLUSIONS: Established fibrosis scores lack diagnostic accuracy to replace liver biopsy for staging of fibrosis, giving similar results as compared to using ALT alone. New diagnostic tools are needed for Noninvasive risk-stratification in paediatric NAFLD.

A Case Report of Steroid-Induced Angioedema and Urticaria.

Physicians regularly use corticosteroids to treat various conditions, attributing their anti-inflammatory and immunosuppressive properties. Cases of allergic sensitivity reactions and dermatitis induced by corticosteroids are relatively uncommon. We present a case regarding an 81-year-old male with a history of actinic keratosis, atopic dermatitis, and psoriasis, who experienced a Type I hypersensitivity reaction with facial angioedema and urticaria on his axilla, torso, and popliteal fossa that developed after treatment with oral prednisolone. This episode also exacerbated his previously diagnosed psoriasis. To treat psoriasis, a dermatologist prescribed clobetasol topical ointment, which did not alleviate the symptoms; instead, it only exacerbated the rash, and he was subsequently referred for corticosteroid allergy testing. North American 85 Comprehensive Series patch testing revealed a positive test for various classes of steroids, including clobetasol-17-propionate, budesonide, and dexamethasone, thus proving a T cell-mediated allergy to corticosteroids.

Common mechanisms in pediatric acute liver failure.

Acute liver failure (ALF) is a rare but potentially fatal disease in children. The etiology is multifactorial, including infection, autoimmune, and genetic disorders, as well as indeterminate hepatitis, which has a higher requirement for liver transplantation. Activation of the innate and adaptive immune systems leads to hepatocyte-specific injury which is mitigated by T regulatory cell activation. Recovery of the native liver depends on activation of apoptotic and regenerative pathways, including the integrated stress response (ISR; e.g., PERK), p53, and HNF4α. Loss-of-function mutations in these pathways cause recurrent ALF in response to non-hepatotropic viruses. Deeper understanding of these mechanisms will lead to improved diagnosis, management, and outcomes for pediatric ALF.

Comparison of the Lipidomic Signature of Fatty Liver in Children and Adults: A Cross-Sectional Study.

OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD) is an increasingly common condition in children characterised by insulin resistance and altered lipid metabolism. Affected patients are at increased risk of cardiovascular disease (CVD) and children with NAFLD are likely to be at risk of premature cardiac events. Evaluation of the plasma lipid profile of children with NAFLD offers the opportunity to investigate these perturbations and understand how closely they mimic the changes seen in adults with cardiometabolic disease. METHODS: We performed untargeted liquid chromatography-mass spectrometry (LC-MS) plasma lipidomics on 287 children: 19 lean controls, 146 from an obese cohort, and 122 NAFLD cases who had undergone liver biopsy. Associations between lipid species and liver histology were assessed using regression adjusted for age and sex. Results were then replicated using data from 9500 adults with metabolic phenotyping. RESULTS: More severe paediatric NAFLD was associated with lower levels of long chain, polyunsaturated phosphatidylcholines (pC) and triglycerides (TG). Similar trends in pC and TG chain length and saturation were seen in adults with hepatic steatosis; however, many of the specific lipids associated with NAFLD differed between children and adults. Five lipids replicated in adults (including PC(36:4)) have been directly linked to death and cardiometabolic disease, as well as indirectly via genetic variants. CONCLUSION: These findings suggest that, whilst similar pathways of lipid metabolism are perturbed in paediatric NAFLD as in cardiometabolic disease in adults, the specific lipid signature in children is different.

Sclerosing Cholangitis in Pediatric Inflammatory Bowel Disease: Early Diagnosis and Management Affect Clinical Outcome.

OBJECTIVE: To describe the characteristics and clinical course of children and young persons with inflammatory bowel disease (IBD) and sclerosing cholangitis (SC). STUDY DESIGN: Retrospective analysis of clinical characteristics, management, and outcome of two separate cohorts of children and young persons with IBD-SC managed in a tertiary pediatric gastroenterology center and in a tertiary pediatric hepatology center in the UK. RESULTS: Eighty-two pediatric patients (31% female) with IBD-SC and a mean age at diagnosis of 11.9 ± 2.8 years were followed up for a mean of 6.8 ± 3.3 years. The most common type of IBD was ulcerative colitis (55%), followed by unclassified IBD (30%) and Crohn's disease (15%). Autoimmune SC (ASC) was diagnosed in 72%, and small duct SC was diagnosed in 28%. Complication-free and native liver survival were 96% and 100%, respectively, at 5 years after diagnosis and 75% and 88%, respectively, at 10 years after diagnosis. Patients in the gastroenterology center, who were diagnosed with liver disease sooner after diagnosis of IBD compared with the hepatology center cohort (mean, 2.7 ± 6.1 months vs 9.3 ± 19.4 months; P = .03), did not develop liver-related complications during follow-up. CONCLUSIONS: Our data suggest that children with IBD-SC have better clinical outcomes than have been reported previously, particularly if diagnosed early. We recommend prompt assessment for SC, including liver biopsy and biliary imaging, when liver function abnormalities are detected in a children diagnosed with IBD.

Evaluations of Lifestyle, Dietary, and Pharmacologic Treatments for Pediatric Nonalcoholic Fatty Liver Disease: A Systematic Review.

BACKGROUND & AIMS: There are no approved treatments for pediatric nonalcoholic fatty liver disease (NAFLD) and there is a lack of consensus on the best outcome measure for randomized controlled trials. We performed a systematic review of treatments tested for pediatric NAFLD, the degree of heterogeneity in trial design, and endpoints analyzed in these studies. METHODS: We searched publication databases and clinical trial registries through January 7, 2018 for randomized controlled trials (published and underway) of children (<18 years) with NAFLD. We assessed improvements in histologic features, radiologic and biochemical markers of reduced fibrosis, metabolic syndrome parameters, and adverse events. The quality of the trials was assessed using a modified version of the Cochrane risk of bias tool. RESULTS: Our final analysis included 21 randomized controlled trials, comprising 1307 participants (mean age, 12.6 years; 63% male; mean duration of intervention, 8 months). Most studies evaluated weight loss with lifestyle intervention (n=8), oral polyunsaturated fatty acid treatment (PUFAs, n=6), or oral antioxidant treatment (n=7). Biomarkers of NAFLD decreased with weight loss, but most studies did not include histologic data. Trials of antioxidants were heterogeneous; some reported reduced histologic features of steatohepatitis with no effect on triglycerides or insulin resistance. PUFAs and probiotics reduced radiologic markers of steatosis, insulin resistance, and levels of triglycerides. Only 38% of the trials had biopsy-proven NAFLD as an inclusion criterion. There was heterogeneity in trial primary endpoints; 10 studies (48%) used levels of aminotransferases or ultrasonography findings as a primary endpoint and only 3 trials (14%) used histologic features as the primary endpoint. We identified 13 randomized controlled trials that are underway in children with NAFLD. None of the protocols include collection of liver biopsies; 9 trials (69%) will use magnetic resonance imaging quantification of steatosis as a primary outcome. CONCLUSIONS: In a systematic review of published and active randomized controlled trials of children with NAFLD, we found a large amount of heterogeneity in study endpoints and inclusion criteria. Few trials included histologic analyses. Antioxidants appear to reduce some features of steatohepatitis. Effects of treatment with lifestyle modification, PUFAs, or probiotics have not been validated with histologic analysis. Trials that are underway quantify steatosis magnetic resonance imaging-outcomes are anticipated.

The global prevalence and genetic spectrum of lysosomal acid lipase deficiency: A rare condition that mimics NAFLD.

BACKGROUND & AIMS: Lysosomal acid lipase deficiency (LAL-D) is an autosomal recessive condition that may present in a mild form (cholesteryl ester storage disease [CESD]), which mimics non-alcoholic fatty liver disease (NAFLD). It has been suggested that CESD may affect 1 in 40,000 and is under-diagnosed in NAFLD clinics. Therefore, we aimed to estimate the prevalence of LAL-D using analysis of genetic variation in LIPA. METHODS: MEDLINE and EMBASE were systematically searched for previously reported disease variants and prevalence estimates. Previous prevalence estimates were meta-analysed. Disease variants in LIPA were annotated with allele frequencies from gnomAD and combined with unreported major functional variants found in humans. Pooled ethnicity-specific prevalences for LAL-D and CESD were calculated using the Hardy-Weinberg equation. RESULTS: Meta-analysis of existing genetic studies estimated the prevalence of LAL-D as 1 per 160,000 (95% CI 1 per 65,025-761,652) using the allele frequency of c.894G>A in LIPA. A total of 98 previously reported disease variants in LIPA were identified, of which 32/98 were present in gnomAD, giving a prevalence of 1 per 307,482 (95% CI 257,672-366,865). Wolman disease was associated with more loss-of-function variants than CESD. When this was combined with 22 previously unreported major functional variants in LIPA identified in humans, the pooled prevalence of LAL-D was 1 per 177,452 (95% CI 149,467-210,683) with a carrier frequency of 1 per 421. The prevalence is lowest in those of East Asian, South Asian, and Finnish ancestry. CONCLUSION: Using 120 disease variants in LIPA, these data can reassure clinicians that LAL-D is an ultra-rare disorder. Given the therapeutic capability of sebelipase alpha, investigation for LAL-D might be included in second-line metabolic screening in NAFLD. LAY SUMMARY: Lysosomal Acid Lipase Deficiency (LAL-D) is a rare genetic condition that can cause severe liver disease, but it is difficult to diagnose and sometimes can look like simple fatty liver. It was not clear how common LAL-D was and whether many cases were being missed. To study this, we searched for all genetic mutations that could cause LAL-D, calculated how common those mutations were, and added them up. This let us estimate that LAL-D affects roughly 1 in 175,000 people. We conclude that LAL-D is a very rare condition, but it is treatable so may be included in a 'second-line' of tests for causes of fatty liver.

The global prevalence of Wilson disease from next-generation sequencing data.

PURPOSE: Wilson disease (WD) is an autosomal recessive disorder of copper metabolism, caused by pathogenic variants in ATP7B. We aimed to (1) perform a meta-analysis of previous WD prevalence estimates, (2) estimate the prevalence of WD from population sequencing data, and (3) generate an ATP7B gene variant database. METHODS: MEDLINE and EMBASE were systematically searched. Previous prevalence estimates were subjected to meta-analysis. All previously reported pathogenic ATP7B variants were compiled and annotated with gnomAD allele frequencies. Pooled global and ethnicity-specific genetic prevalences for WD were generated using the Hardy-Weinberg equation. RESULTS: Meta-analysis of genetic studies of WD prevalence gave an estimate 12.7 per 100,000 (95% confidence interval [CI]: 6.3-23.0). We developed a referenced, searchable ATP7B database comprising 11,520 variants including 782 previously reported disease variants, which can be found at http://www.wilsondisease.tk/ ; 216/782 of these were present in gnomAD, remained after filtering by allele frequency, and met American College of Medical Genetics and Genomics criteria. Based on these, the genetic prevalence of WD was 13.9 per 100,000 (95% CI: 12.9-14.9), or 1 per 7194. Combining this with 60 predicted pathogenic variants gave a birth prevalence of 15.4 per 100,000 (95% CI: 14.4-16.5). CONCLUSION: The genetic prevalence of Wilson disease may be greater than previous estimates.

European paediatric non-alcoholic fatty liver disease registry (EU-PNAFLD): Design and rationale.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in children and has the potential to progress to advanced fibrosis/cirrhosis, end-stage liver disease and hepatocellular carcinoma. However, the natural history of the condition is poorly understood and there are no approved treatments. The European Paediatric Non-Alcoholic Fatty Liver Disease Registry (EU-PNAFLD) is a multi-centre registry of paediatric NAFLD that will serve as a prospective, observational, natural history study and provide a tractable back-bone to support recruitment into subsequent interventional trials. Collection of samples into a bio-repository will facilitate translational studies, including genome sequencing and metabolomics. EU-PNAFLD will work closely alongside the existing adult European NAFLD Registry to obtain data on clinical outcomes after 20-30 years. Through an international, well-characterised large-scale cohort, EU-PNAFLD will address the key questions in paediatric NAFLD and benefit patients with the condition.

Gathering momentum for the way ahead: fifth report of the Lancet Standing Commission on Liver Disease in the UK.

This report presents further evidence on the escalating alcohol consumption in the UK and the burden of liver disease associated with this major risk factor, as well as the effects on hospital and primary care. We reiterate the need for fiscal regulation by the UK Government if overall alcohol consumption is to be reduced sufficiently to improve health outcomes. We also draw attention to the effects of drastic cuts in public services for alcohol treatment, the repeated failures of voluntary agreements with the drinks industry, and the influence of the industry through its lobbying activities. We continue to press for reintroduction of the alcohol duty escalator, which was highly effective during the 5 years it was in place, and the introduction of minimum unit pricing in England, targeted at the heaviest drinkers. Results from the introduction of minimum unit pricing in Scotland, with results from Wales to follow, are likely to seriously expose the weakness of England's position. The increasing prevalence of obesity-related liver disease, the rising number of people diagnosed with type 2 diabetes and its complications, and increasing number of cases of end-stage liver disease and primary liver cancers from non-alcoholic fatty liver disease make apparent the need for an obesity strategy for adults. We also discuss the important effects of obesity and alcohol on disease progression, and the increased risk of the ten most common cancers (including breast and colon cancers). A new in-depth analysis of the UK National Health Service (NHS) and total societal costs shows the extraordinarily large expenditures that could be saved or redeployed elsewhere in the NHS. Excellent results have been reported for new antiviral drugs for hepatitis C virus infection, making elimination of chronic infection a real possibility ahead of the WHO 2030 target. However, the extent of unidentified cases remains a problem, and will also apply when new curative drugs for hepatitis B virus become available. We also describe efforts to improve standards of hospital care for liver disease with better understanding of current service deficiencies and a new accreditation process for hospitals providing liver services. New commissioning arrangements for primary and community care represent progress, in terms of effective screening of high-risk subjects and the early detection of liver disease.

The pharmacological management of NAFLD in children and adolescents.

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) represents a spectrum, including 'simple' steatosis, non-alcoholic steatohepatitis (NASH), and fibrosis. Increasing prevalence of NAFLD has followed the international rise in obesity and lifestyle modification is the mainstay therapy for children. To date, pharmacological trials have had varying efficacy but a large number of new agents are in early phase trials for adults. Areas covered: This review explores the effect of current and potential future paediatric NAFLD treatments in terms of histological and biochemical endpoints. The potential for the extension of adult treatments to children is discussed, as well as what limits the use of certain agents in children. Expert commentary: No drugs have yet to be licenced for NAFLD. Trial heterogeneity makes comparison of drugs between studies challenging. FXR agonists are yet to be trialled in children but may represent a safe and potentially efficacious therapy. Future treatments would likely encompass a multimodal approach that may include bariatric surgery.

Update on lipid species and paediatric nonalcoholic fatty liver disease.

PURPOSE OF REVIEW: To describe the recent advances in our understanding of fatty acids and lipids in paediatric nonalcoholic fatty liver disease (NAFLD) and their future implications. RECENT FINDINGS: Data have been accumulated to suggest that ceramides are the main drivers of hepatic insulin resistance in NAFLD, and inhibition of ceramide synthesis improves histology in mice.Saturated fatty acids formed by de novo lipogenesis generate increased lipotoxicity compared with dietary-derived saturated fatty acids.Hepatic lipogenesis and associated insulin resistance have been found to be influenced by several novel proteins, including E2F1, cyclic AMP response element binding protein transcriptional coactivator 2, Raptor, and eukaryotic initiation factor 6. There are encouraging data from animal models that modulation of these could be therapeutic targets.Human and animal metabolomics and lipidomics data have been used to generate a lipid signature for NAFLD and nonalcoholic steatohepatitis. Serum lipidomics appears to correlate with hepatic lipidomics.Therapeutic trials of polyunsaturated fatty acids in children have had mixed results, with some reductions in noninvasive biomarkers. SUMMARY: Multiple new pathways for drug targets have been identified, and use of lipidomics is likely to become a noninvasive method for assessing disease. However, much of the data for paediatric NAFLD are extrapolated from adult or animal studies.

How Useful Are Monogenic Rodent Models for the Study of Human Non-Alcoholic Fatty Liver Disease?

Improving understanding of the genetic basis of human non-alcoholic fatty liver disease (NAFLD) has the potential to facilitate risk stratification of affected patients, permit personalized treatment, and inform development of new therapeutic strategies. Animal models have been widely used to interrogate the pathophysiology of, and genetic predisposition to, NAFLD. Nevertheless, considerable interspecies differences in intermediary metabolism potentially limit the extent to which results can be extrapolated to humans. For example, human genome-wide association studies have identified polymorphisms in PNPLA3 and TM6SF2 as the two most prevalent determinants of susceptibility to NAFLD and its inflammatory component (NASH), but animal models of these mutations have had only variable success in recapitulating this link. In this review, we critically appraise selected murine monogenic models of NAFLD, NASH, and hepatocellular carcinoma (HCC) with a focus on how closely they mirror human disease.

Changes in plasma chemokine C-C motif ligand 2 levels during treatment with eicosapentaenoic acid predict outcome in patients undergoing surgery for colorectal cancer liver metastasis.

The mechanism of the anti-colorectal cancer (CRC) activity of the omega-3 fatty acid eicosapentaenoic acid (EPA) is not understood. We tested the hypothesis that EPA reduces expression of chemokine C-C motif ligand 2 (CCL2), a pro-inflammatory chemokine with known roles in metastasis.We measured CCL2 in clinical samples from a randomized trial of EPA in patients undergoing liver surgery for CRC liver metastasis (LM) and preclinical models. Genome-wide transcriptional profiling of tumors from EPA-treated patients was performed.EPA decreased CCL2 synthesis by CRC cells in a dose-dependent manner. CCL2 was localized to malignant epithelial cells in human CRCLM. EPA did not reduce CCL2 content in human or mouse tumors compare to control. However, EPA treatment was associated with decreased plasma CCL2 levels compared with controls (P=0.04). Reduction in plasma CCL2 following EPA treatment predicted improved disease-free survival (HR 0.32; P=0.003). Lack of 'CCL2 response' was associated with a specific CRCLM gene expression signature.In conclusion, reduction in plasma CCL2 in patients with CRCLM treated with EPA predicts better clinical outcome and a specific tumor gene expression profile. Further work is needed to validate CCL2 as a therapeutic response biomarker for omega-3 fatty acid treatment of CRC patients.

Portal inflammation is independently associated with fibrosis and metabolic syndrome in pediatric nonalcoholic fatty liver disease.

UNLABELLED: Pediatric nonalcoholic fatty liver disease (NAFLD) histology demonstrates variable amounts of portal inflammation, which may be associated with more severe liver disease and fibrosis. We assessed the relationship between portal inflammation, hepatic fibrosis, and the metabolic syndrome in pediatric NAFLD. Children with biopsy-proven NAFLD were eligible for inclusion. Histology was assessed using Kleiner fibrosis stage and the Nonalcoholic Steatohepatitis Clinical Research Network system for portal inflammation. Patients were divided by histology into type 1, type 2, and overlap NAFLD. Multivariable ordinal logistic regression was used to determine factors associated with fibrosis and portal inflammation. The 430 Caucasian children were divided into 52 with type 1, 95 with type 2, and 283 with overlap NAFLD. Those with type 2 had a more severe metabolic phenotype, with higher body mass index z score (2.0 versus 1.6, P < 0.0001), waist circumference centile (96th versus 90th, P < 0.0001), and triglycerides (84 versus 77 mg/dL, P = 0.01) and lower high-density lipoprotein (46 versus 60 mg/dL, P = 0.004) than those with type 1. Similarly, those with overlap NAFLD had a more severe phenotype. Stage 2-3 fibrosis was present in 69/283 (24%) with overlap NAFLD. Portal inflammation was associated with stage 2-3 fibrosis on multivariable analysis (95% confidence interval 1.4-5.2, odds ratio = 3.7). Waist circumference centile was associated with portal inflammation (95% confidence interval 1.2-3.4, odds ratio = 2.0). CONCLUSION: Portal inflammation is associated with more advanced pediatric NAFLD and features of the metabolic syndrome.

Paediatric non-alcoholic fatty liver disease: a practical overview for non-specialists.

Non-alcoholic fatty liver disease (NAFLD) is the most common paediatric liver disease with a prevalence of almost 10%; therefore, the majority of affected patients are under the care of general practitioners and non-specialists. The condition is caused by central obesity with insulin resistance with additional factors influencing inflammatory activity (steatohepatitis). Ongoing inflammation leads to fibrosis and end-stage liver disease, though this will usually occur after children have transitioned into adult care. However, their main morbidity and mortality is from type 2 diabetes and complications of atherosclerosis. The minority of children undergo biopsy but currently there is no other method to accurately assess the stage of disease. Management is focused at weight loss through a combination of diet and exercise. Here, we present a current review of paediatric NAFLD aimed at non-specialists, with practice points for implementation.

Systematic review of definitions of failure in revisional bariatric surgery.

BACKGROUND: There are no agreed definitions as to what constitutes a 'failure' of the primary bariatric procedure in relation to weight loss. METHODS: The MEDLINE database for primary research articles was searched using obesity [title] or bariatric [title] and revision [title] or revisional [title]. RESULTS: The MEDLINE search retrieved 174 studies. After duplicates and exclusions were removed, 60 articles underwent analysis. Fifty-one studies included inadequate weight loss or weight regain as an indication for revision: 31/51 (61 %) gave no definition of failure, 7/20 quoted <50 % of excess weight loss at 18 months and 6/20 used <25 % excess weight loss. CONCLUSIONS: The majority of published studies do not define failure of bariatric surgery, and <50 % excess weight loss at 18 months was the most frequent definition identified.

Severe asymptomatic non-alcoholic fatty liver disease in routine diabetes care; a multi-disciplinary team approach to diagnosis and management.

OBJECTIVES: To prospectively use a non-invasive algorithm to identify asymptomatic, advanced non-alcoholic fatty liver disease (NAFLD) in a secondary care diabetes clinic and to determine the short-term effect of a multi-disciplinary team (MDT) approach in a liver clinic. RESEARCH DESIGN AND METHODS: NAFLD Fibrosis Score (NFS) was calculated in 64 asymptomatic patients with type 2 diabetes. Advanced fibrosis was identified using transient elastography and confirmed with liver biopsy. In a subsequent retrospective study, 95 patients newly referred to the NAFLD MDT clinic were investigated and the impact of the MDT approach assessed. RESULTS: 25/64 (39.0%) of patients with diabetes had a low NFS (<-1.455). 39/64 (61.0%) patients had a high or indeterminate NFS and were referred for review in the NAFLD MDT clinic, of which 23/39 attended for assessment. 19/23 (82.6%) were diagnosed with NAFLD, of which 6/19 (31.6%) patients had a positive transient elastography (≥8 kPa). Liver biopsy confirmed advanced fibrosis in 5/6 cases, with moderate fibrosis in 1 case. In the retrospective study, 65/95 (68.4%) new referrals to the NAFLD MDT clinic had a diagnosis of NAFLD. Over a median 98 days (IQR 70-182) follow-up, there was a significant improvement in weight (-0.8 kg; P = 0.024), total cholesterol (-0.2 mmol/L; P = 0.044), ALT (alanine transmaminase, -12.5 IU/L; P < 0.001) and GGT (gammu-glutamyl transferase, -13.0 IU/L; P < 0.0001). 7/28 (25%) of patients with diabetes achieved >5% weight loss. CONCLUSIONS: A significant proportion of asymptomatic patients attending type 2 diabetes clinics have undiagnosed advanced NAFLD fibrosis. An MDT approach to NAFLD results in short-term improvements in metabolic and liver parameters.
