Nonalcoholic Fatty Liver

Nonalcoholic fatty liver disease (NAFLD) is closely correlated with insulin resistance and several metabolic syndrome features, but whether it could increase the risk of cardiovascular disease remains undefined. To assess the association between NAFLD and the risk of cardiovascular outcomes, we systematically searched the MEDLINE, Embase, and the Cochrane Library database (1947 to October 2012) by using Medical Subject Heading search terms and a standardized protocol. Randomized controlled trials, case-control, and prospective studies carried out in human adults, in which the unadjusted and multivariate adjusted odds ratios with corresponding 95% confidence interval (CI) for cardiovascular disease with NAFLD were reported. The search yielded 4 cross-sectional studies and 2 prospective cohort studies including 7,042 participants. The pooled effects estimate showed that NAFLD was a predictor of cardiovascular disease (odds ratio 1.88, 95% CI, 1.68 to 2.01; ). The random effects summary estimate indicated that NAFLD retained a significant association with cardiovascular outcomes independent of conventional risk factors after adjustment for established cardiovascular risk factors (odds ratio 1.50, 95% CI, 1.21 to 1.87; ). These results indicate that NAFLD is a strong independent predictor of cardiovascular disease and may play a central role in the cardiovascular risk of metabolic syndrome.

Management Of Complications

Nonalcoholic fatty liver disease (NAFLD) represents a spectrum of disorders from a benign steatosis to hepatocellular carcinoma (HCC). Metabolic syndrome, mainly obesity, plays an important role, both as an independent risk factor and in the pathogenesis of NAFLD. With the progressive epidemics of obesity and diabetes mellitus, the prevalence of NAFLD and its associated complications is expected to increase dramatically. Therapeutic strategies for treating NAFLD and metabolic syndrome, particularly obesity, are continuously being refined. Their goal is the prevention of NAFLD by the management of risk factors, prevention of progression of the disease, as well as management of complications, ultimately preventing morbidity and mortality. Optimal management of NAFLD and metabolic syndrome requires a multidisciplinary collaboration between the government as well as the health system including the nutritionist, primary care physician, radiologist, hepatologist, oncologist, and transplant surgeon. An awareness of the clinical presentation, risk factors, pathogenesis, diagnosis, and management is of paramount importance to a radiologist, both from the clinical perspective as well as from the imaging standpoint. With expertise in imaging modalities as well as minimally invasive percutaneous endovascular therapies, radiologists play an essential role in the comprehensive management, which is highlighted in this article, with cases from our practice. We also briefly discuss transarterial embolization of the left gastric artery (LGA), a novel method that promises to have an enormous potential in the minimally invasive management of obesity, with details of a case from our practice.

The Metabolic Syndrome

Nonalcoholic fatty liver disease (NAFLD) has emerged as the most frequent cause of liver disease worldwide, comprising a plethora of conditions, ranging from steatosis to end-stage liver disease. Cardiovascular disease (CVD) has been associated with NAFLD and CVD-related events represent the main cause of death in patients with NAFLD, surpassing liver-related mortality. This association is not surprising as NAFLD has been considered a part of the metabolic syndrome and has been related to numerous CVD risk factors, namely, insulin resistance, abdominal obesity, dyslipidemia, hyperuricemia, chronic kidney disease, and type 2 diabetes. Moreover, both NAFLD and CVD present similar pathophysiological mechanisms, such as increased visceral adiposity, altered lipid metabolism, increased oxidative stress, and systemic inflammation that could explain their association. Whether NAFLD increases the risk for CVD or these diagnostic entities represent distinct manifestations of the metabolic syndrome has not yet been clarified. This review focuses on the relation between NAFLD and the spectrum of CVD, considering the pathophysiological mechanisms, risk factors, current evidence, and future directions.

Introduction: We sought to characterize the association of three adiposity-related risk factors - obesity, metabolic syndrome, and nonalcoholic fatty liver disease (NAFLD) - with the outcomes of increased inflammation and subclinical atherosclerosis. Methods: We conducted a cross-sectional analysis of 3976 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) with adequate CT imaging to diagnose NAFLD. For the study exposures, obesity was defined as BMI ≥30 kg/m 2 , metabolic syndrome by ATP III criteria, and NAFLD using non-contrast cardiac CT and a liver/spleen attenuation ratio (L/S) 0. In order to assess for a possible gradient-response, adjusted logistic regression was used to examine the association of a stepwise increase in the number of three adiposity-related risk factors with increased inflammation and subclinical atherosclerosis. Additional models were conducted stratifying by gender or ethnicity. Results: Mean age of participants was 63 years, 45% were male, 37% were white, 10% Chinese, 30% African American, and 23% Hispanic. NAFLD was associated with an odds ratio for high hs-CRP and CAC>0 of 1.54 (1.27-1.87) and 1.41 (1.15-1.73), respectively, adjusting for obesity, metabolic syndrome and traditional risk factors. There was a positive interaction between female gender and NAFLD in the association with high hs-CRP (p=0.01). There was no interaction by race. Importantly, with increasing number of adiposity-related risk factors, the odds ratios of high hs-CRP and CAC>0 increased in a graded fashion, suggesting a collective association (Figure). Conclusion: There is an association between three adiposity-related risk factors - obesity, metabolic syndrome, and NAFLD - with both increased inflammation and subclinical coronary atherosclerosis.

Bcakgrounds: Non alcoholic fatty liver disease (NAFLD) has been linked independently to cardiovascular disease (CVD) but It is largely unknown if such a relationship between NAFLD and CVD risk relates to severity of liver disease or if it is independent of other potential confounding factors Methods: This study included 30,172 subjects. Based on the presence or absence of steatosis on ultrasound and serum alanine aminotransferase (ALT), subjects were divided into controls, an increased serum ALT group without steatosis and a group with presumed nonalcoholic fatty liver disease (NAFLD), which included a steatosis alone group and a group with presumed non alcoholic steatohepatitis (NASH) with steatosis and an elevated ALT. Results: The odds ratio for 10-year risk by total Framingham risk scores ≥10% was 5.3 times higher in NASH groups. The prevalence of diabetes, hypertension, elevated CRP and metabolic syndrome were all increased up to 15 fold over controls, independent of age, BMI, smoking and exercise habits. Overall CVD risk was significantly greater in NASH than in either steatosis or raised ALT alone. Conclusion: Young, non-obese subjects with NAFLD are at significantly increased CVD risk, especially those with NASH. As well as specific therapy for liver disease, a diagnosis of NAFLD should lead to targeted risk assessment and risk factor modification. Table 1.
