The American Gastroenterological Association (2002), Canadian Medical Association (2005), and the Centers for Disease Control and Prevention (2006) released guidelines to screen patients with mild elevations of liver enzymes for hepatitis B and hepatitis C. Mildly elevated liver enzymes were defined as less than five times the upper limit of normal, but above the normal reference range. The rationale for this recommendation was based on many factors including cost effectiveness, lab variation, and ultimately, for better patient care.Chronic hepatitis B and C have values of transaminases that fluctuate between normal and mildly abnormal. Screening patients with even mild elevations of transaminases allows many chronic hepatitis patients to be diagnosed early in the course of their disease. Diagnosing these patients early in their disease course leads to better treatment response, decreased progression to cirrhosis, lower viral loads leading to decreased incidence of extrahepatic manifestations, prevention of hepatocellular carcinoma, and decreased likelihood of liver transplantation.There are organizations which recommend discontinuing hepatotoxic medications such as acetaminophen or nonsteroidal anti-inflammatory drugs and reevaluating the patient in three months. However, this recommendation misses a number of hepatitis patients for the reasons aforementioned. The obesity epidemic has clouded the diagnosis of hepatitis B/C as patients that have obesity, diabetes mellitus, and metabolic syndrome are not being screened due the presumptive diagnosis of nonalcoholic fatty liver disease.Not screening patients in the setting of obesity is not cost-effective and also leads to increased morbidity, as we will discuss in this manuscript. Additionally, it has been proven in the literature that it is more cost-effective to screen for hepatitis B/C in high-prevalence areas, than to reassess the patient months later, and potentially miss a diagnosis of hepatitis B/C. The overall goal of this study is to increase screening awareness of patients with mild transaminitis elevations through publication in order to diagnose patients with hepatitis B and C prior to the development of chronic liver disease.

Chronic hepatitis B (CHB) is a global health issue that increases the risk of liver cirrhosis and hepatocellular carcinoma in infected patients. Metabolic syndrome (MetS) is a disease endemic mostly to the developed countries. It is associated with high cardiovascular mortality and morbidity, diabetes mellitus as well as cancer. In this manuscript, we systematically review the published data on the relationship between MetS and CHB infection. Multiple studies have described highly variable correlations between CHB on one hand and MetS, non-alcoholic fatty liver disease and dyslipidemia on the other. No association between CHB and diabetes mellitus or atherosclerosis has been described as of now. The presence of MetS in patients infected with hepatitis B virus increases the risk of fibrosis, cirrhosis and hepatocellular carcinoma. Appropriate lifestyle, but also pharmacological interventions are needed to prevent the development of these complications.

Hepatocellular carcinoma (HCC) is the second cause of death due to malignancy in the world, following lung cancer. The geographic distribution of this disease accompanies its principal risk factors: Chronic hepatitis B virus and hepatitis C virus infection, alcoholism, aflatoxin B1 intoxication, liver cirrhosis, and some genetic attributes. Recently, type II diabetes has been shown to be a risk factor for HCC together with obesity and metabolic syndrome. Although the risk factors are quite well known and it is possible to diagnose HCC when the tumor is less than 1 cm diameter, it remains elusive at the beginning and treatment is often unsuccessful. Liver transplantation is thus far considered the best treatment for HCC as it cures HCC and the underlying liver disease. Using the Milan criteria, overall survival after liver transplantation for HCC is about 70% after 5 years. Many attempts have been made to go beyond the Milan Criteria and according to recent works reasonably good results have been achieved by using a histochemical marker such as cytokeratine 19 and the so-called "up to seven criteria" to divide patients into categories according to their risk of relapse. In addition to liver transplantation other therapies have been proposed such as resection, tumor ablation by different means, embolization and chemotherapy. An important step in the treatment of advanced HCC has been the introduction of sorafenib, the first oral, systemic drug that has provided significant improvement in survival. Treatment of HCC patients must be multidisciplinary and by using the different approaches discussed in this review it is possible to offer prolonged survival and quite good and sometimes even excellent quality of life to many patients.

The incidence rate of hepatocellular carcinoma (HCC) is rising. It is one of the most common cancers worldwide and accounts for substantial morbidity and mortality. Chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and nonalcoholic fatty liver disease (NAFLD) are the most important etiologies of HCC, and effective screening and management strategies are crucial to reduce the HCC risk. For HBV, which accounts for the majority of HCC cases, most infections were acquired via perinatal and early horizontal transmission. Universal vaccination of newborns has led to a decline in HCC incidence compared with the pre-vaccination era. Effective antiviral therapies with nucleos(t)ide analogues or pegylated interferon reduced the incidence of HCC. For HCV, the emergence of effective direct-acting antiviral (DAA) agents has substantially improved cure rates; therefore all patients with HCV should be considered for DAA treatment. The most important obstacle in eliminating HCV is access to therapy. For NAFLD, the global incidence is increasing rapidly, thus its impact on HCC incidence may be explosive. Progression to HCC in NAFLD happens particularly in those with nonalcoholic steatohepatitis (NASH) and exacerbated by metabolic syndrome, or PNPLA3 gene polymorphism. Lifestyle changes are imperative while drug therapy has yet to demonstrate substantive protective effects on HCC prevention. For management of HCC, early diagnosis via imaging surveillance among persons with HCC risk factors remains the most important strategy to identify early-stage disease appropriate for resection or transplantation.

The growing burden of non-alcoholic fatty liver disease (NAFLD) parallels the increasing prevalence of obesity in Asia. The overall prevalence of NAFLD in Asia is now estimated to be 29.6% and may have surpassed that in Western populations. NAFLD increases with increasing age and is closely associated with metabolic syndrome. Ethnic differences exist in the prevalence of NAFLD, but the underlying factors are unclear. There were initial concerns about lean NAFLD being associated with more severe liver disease and increased mortality, but subsequent studies suggested otherwise. Only some NAFLD patients progress to develop advanced liver fibrosis and cirrhosis, while the liver status remains unchanged in the majority; fibrosis stage is the most important predictor of disease-specific mortality in NAFLD. Surveillance for hepatocellular carcinoma (HCC) remains a challenge due to undiagnosed cirrhosis and the development of HCC in non-cirrhotic NAFLD patients. Diabetes mellitus shares a bidirectional relationship with NAFLD; NAFLD is highly prevalent among patients with diabetes mellitus, and diabetes mellitus is associated with more severe NAFLD. Chronic hepatitis B (CHB) is a major cause of chronic liver disease in Asia; NAFLD and CHB are increasingly observed together because of the increasing prevalence of NAFLD. Despite studies reporting favorable virologic outcome in CHB patients with NAFLD, NAFLD has been found to be independently associated with fibrosis progression and poorer prognosis in CHB patients. Therefore, NAFLD in CHB patients should be given more attention.
