Abstract
Since the publication of the guidelines for the assessment and management of non‑alcoholic fatty liver disease (NAFLD) by the Asia–Pacific Working Party on NAFLD in 2007,1 our understanding of the clinical characteristics and natural history of NAFLD has improved, and there have been developments in the assessment and treatment of NAFLD. It is therefore timely to update the guidelines in light of new evidence. This document presents the recommendations of the Asia–Pacific Working Party on NAFLD. The exercise was supported by the Journal of Gastroenterology and Hepatology Foundation. Members performed a systematic review of the literature on specified domains of interest, thereby allowing them to provide recommendations on different aspects of the clinical assessment and management of patients with NAFLD. The contents and statements were then discussed through face-to-face meetings and e-mail communications. The statements in this document follow the Grading of Recommendation Assessment, Development, and Evaluation approach (Table 1).2 The final grading of evidence and recommendations was determined by majority vote. These guidelines cover various aspects in the management of NAFLD, including diagnosis, screening, assessment, and treatment. While most evidence came from studies on adults identified to be at risk of metabolic disorder and after exclusion of other liver diseases, two special populations are included in this document. NAFLD in children and adolescents is becoming increasingly prevalent and may have devastating consequences owing to the long duration of fatty liver disease. In addition, chronic viral hepatitis is highly prevalent in Asia–Pacific countries, and the impact of concomitant fatty liver, a much discussed topic both for hepatitis B and C, is re-evaluated here for its long-term clinical significance and implications for patient care. A clear, reproducible definition of NAFLD is required for clinical practice and epidemiological studies because there are several causes of fatty liver and steatohepatitis, each with differing management implications and clinical outcomes. An unresolved definitional and semantic challenge is that two or more etiological factors commonly interact to influence the incidence, severity, and outcome of fatty liver. The current established “negative” definition of NAFLD requires (i) evidence of hepatic steatosis by either imaging or histology and (ii) absence of other causes of hepatic fat accumulation from conditions such as significant alcohol consumption, hepatitis C, medication use, or hereditary disorders. While it has been acknowledged that “in the majority of patients” NAFLD is associated with metabolic risk factors such as obesity, diabetes mellitus, and dyslipidemia, this fails to identify overnutrition (as opposed to established obesity) as pivotal, or to account for the approximately 25% of patients in Asian cohorts who have fatty liver but are not obese. However, the vast majority of such “non-obese NAFLD” patients exhibit insulin resistance. In this respect, it is also critical to note that family history of diabetes (genetic predisposition) and prediabetes as well as established diabetes are commonly associated with NAFLD. Finally, it has now been clearly demonstrated that loss of 10% of bodyweight (in overweight persons) completely reverses all elements of non-alcoholic steatohepatitis (“NASH”) pathology, including liver fibrosis. This cements the role of overnutrition in the causation of NAFLD. Review articles from Europe have tended towards a more positive definition of NAFLD, as did the original Asia–Pacific Guidelines of 2007. The recommended definition for the 11th Revision of the International Classification of Diseases is “NAFLD is characterized by fatty liver (defined as earlier) related to over-nutrition in the absence of excessive alcohol consumption.” The majority of cases of NAFLD show steatosis with no or minimal liver inflammation. The term favored by the American Association for the Study of Liver Diseases (AASLD) for this, non-alcoholic fatty liver, has not been adopted by the 11th Revision of the International Classification of Diseases as it seems ambiguous. Specifically, all NAFLD cases have fatty liver, whether steatohepatitis (NASH) is present or not. Instead, if the pathology is known, the terminology should be “NAFLD without NASH” or “simple steatosis,” “NASH,” and “with or without fibrosis or cirrhosis” for either category. Between 10% and 25% of NAFLD cases show steatohepatitis, that is, NASH. The hallmarks are conspicuous hepatocyte injury (especially ballooning and apoptosis) and substantial liver inflammation. NASH is more likely to be associated with liver fibrosis than cases showing only steatosis. Notwithstanding the likely importance of NASH in leading to fibrosis, it is the presence of fibrosis (with or without NASH) that predicts progression to cirrhosis in clinical outcome studies. Hepatocellular carcinoma (HCC) is a complication of NAFLD, but not exclusively among cases that progressed to cirrhosis (including cases of “cryptogenic cirrhosis”). Besides, it is unclear if a patient must have NASH before progressing to NAFLD-related HCC. No more than one standard drink per day (i.e. 70 g ethanol per week) for women and no more than two standard drinks per day (i.e. 140 g ethanol per week) for men have been used by the National Institutes of Health NASH clinical research network and widely adopted for clinical studies. The relevance of this standard to the populations in the Asia–Pacific region was discussed in the 2007 Guidelines. The proposed levels of alcohol intake are based on evidence about daily alcohol intake and risk of cirrhosis. The “cut-off” values have been set lower than the apparent “threshold levels” so as to avoid the issue of overlap between alcoholic liver disease and obesity, type 2 diabetes (T2DM), and metabolic syndrome in progression to cirrhosis. Patients who may be drinking at safe levels at the time of presentation with liver disease may have a past history of chronic excessive alcohol intake for a prolonged period of time and may have cirrhosis. Lifetime alcohol intake is therefore important and needs to be incorporated into history taking. Over the past three decades, changing Western lifestyles and dietary habits, in addition to relatively high rates of genetic predisposition in several community groups, have increased the prevalence of NAFLD in the Asia–Pacific region. On the basis of hepatic imaging, recent studies suggest that a quarter (95% confidence interval [CI]: 23.3–31.9%) of the general population in Asia has NAFLD, but the proportion of patients with advanced liver fibrosis diagnosed by transient elastography (TE) appears to be low (3.7% among NAFLD patients).3 Obesity, dyslipidemia, T2DM, and metabolic syndrome are established risk factors for developing NAFLD. In addition, several other risk factors for NAFLD have been identified in the Asia–Pacific region. These include hypothyroidism, polycystic ovary syndrome, obstructive sleep apnea, hypopituitarism, and hypogonadism. There may be subtle differences in the phenotype distribution of NAFLD between Asia–Pacific and Western countries. Of particular interest are more frequent “lean NAFLD” and the urban–rural differences of prevalence rates of NAFLD in Asia.4 In addition, Asian people are particularly susceptible, partly owing to body composition differences in fat and muscle and genetic susceptibility via predisposition to T2DM, PNPLA3 SNPs, and polymorphisms in apolipoprotein 3.5 On the other hand, the natural history of NAFLD and its progression to cirrhosis and HCC (when this occurs) is over several decades; the fact that NAFLD in Asian countries may be more recent than in North and South America, for example, may also influence the present distribution of disease phenotypes towards the milder end of the pathological spectrum. There are limited studies evaluating the incidence of NAFLD and the prevalence of NASH in the general population. In Japan, pooled regional NAFLD incidence rate estimates are 52.3 (95%CI: 28.1–96.8) per 1000 person-years.6 Incident NAFLD is not uncommon among Chinese people who are not obese; for instance, 8.9% of lean subjects developed NAFLD during a 5-year follow-up.6 Because the diagnosis of NASH requires a liver biopsy, the population prevalence of NASH in Asia is currently unknown. Among Asian liver biopsy series, NASH can be found in 63.5% (95%CI: 47.7–76.8). In natural history studies involving paired liver biopsies, around 25% of patients may progress from simple steatosis to NASH in 3 years.7 Non-alcoholic steatohepatitis is the most common cause of cirrhosis and HCC in patients without other known etiological causes of liver disease worldwide. Thus, 63.3% of formerly designated cryptogenic cirrhosis cases could finally be attributed to NAFLD because cryptogenic cirrhosis is more associated with metabolic syndrome than other causes of cirrhosis. A study from Japan found that 17 of 320 HCC cases (5.3%) were either associated with NASH or had unknown (“cryptogenic”) etiology.8 “Cryptogenic” HCC also accounted for 5.4% of all HCCs in Korea. null syndrome and its null (i.e. null and null are null common in cryptogenic cirrhosis and HCC null null literature from Asia also null a null null between NAFLD and HCC in null null null null null null The majority of null HCC patients either did not have null cirrhosis or cirrhosis was well null null null null with null B and null cirrhosis with other null However, null from null null long-term studies from this null with null null of liver null are required to null the prevalence and incidence of HCC in NAFLD null null in null NASH patients in null null general null is to null null the null importance of null null and null factors in null the prevalence of NAFLD and its liver null in different null null null null null of the vast Asia–Pacific region. null of the prevalence of NAFLD in children and adolescents null widely between null studies. null liver null null null null null that the prevalence of NAFLD was null in null null children null null to null null null study from null null the prevalence was null in null to null null in null null null the prevalence of NAFLD in null children (defined as the body null null null null null null by null and null null null null null null null that null of null null null children and adolescents had null null However, the null prevalence of NAFLD may be null by this null because liver null is relatively null for null cases with hepatic fat null null null null null null null is null used to null NAFLD null The prevalence of null null levels null null was null in null adolescents null null to null null in the null National Health and null null null null A null study of null null children null null null null a prevalence of null null null of null null null null for null in the general population is likely to be null null in null and null null in null null There are null null null null null as a null null for NAFLD as the null null of null null is not well established and null levels null not null the null null of NAFLD in children or null The standard diagnosis of NASH null on liver null null There were no studies to null NASH prevalence by this null in the Asia–Pacific region.
