Psoriasis is associated with a higher risk of liver diseases. We investigated the impact of hepatic steatosis (European cohort) and hepatic inflammation (United States cohort) on subclinical atherosclerosis. In the European cohort (n=76 psoriasis participants and 76 controls), non-alcoholic fatty liver disease (NAFLD), assessed by the sonographic hepatorenal index (SHRI), was more prevalent in psoriasis than controls (61% vs 45%; p=.04). Psoriasis participants with NAFLD had a higher prevalence of subclinical atherosclerosis (ultrasonographic presence of plaque in femoral or carotid arteries) than psoriasis without NAFLD (61% vs 23%; p=.006) and controls with NAFLD (61% vs 32%; p<.05). SHRI was a determinant of subclinical atherosclerosis in psoriasis (OR, 3.5; p=.01). In the United States cohort, (n=162 psoriasis participants who underwent positron emission tomography and coronary CT angiography), those with high hepatic F-FDG uptake had higher noncalcified (1.3 (0.49 mm) vs 1.0 (0.40 mm)), fibrofatty (0.23 (0.15 mm) vs 0.11 (0.087 mm)), and lipid rich necrotic core (4.3 (2.3 mm) vs 3.0 (1.7 mm)) coronary burden (all p<.001,). Hepatic F-FDG uptake associated with noncalcified (β=0.28; p<.001), fibrofatty (β=0.49; p<.001) and lipid rich necrotic core (β=0.28; p=.003) burden. These results demonstrate the downstream cardiovascular effects of subclinical liver disease in psoriasis.

Insulin resistance in lean and overweight non-diabetic Caucasian adults: Study of its relationship with liver triglyceride content, waist circumference and BMI.

PLoS One 2018 9;13(2):e0192663. Epub 2018 Feb 9.

University of Granada, Granada, Spain.

Aims: Insulin resistance is the pathophysiological precursor of type 2 diabetes mellitus (DM-2), and its relationship with non-alcoholic fatty liver disease (NAFLD) has been widely studied in patients with obesity or metabolic syndrome using not only ultrasound but also liver biopsies or proton magnetic resonance spectroscopy (H1-MRS) to assess liver fat content. In contrast, there are no studies on insulin resistance and NAFLD in lean or overweight Caucasian individuals using H1-MRS or liver biopsies for the quantification of hepatic triglyceride content. Our objectives were to study the presence of insulin resistance in lean and overweight Caucasian adults and investigate its possible relationship with liver triglyceride content, waist circumference (as proxy of visceral adiposity), BMI, and cardiometabolic risk factors.

Methods: A cross-sectional study was conducted in 113 non-obese, non-diabetic individuals classified as overweight (BMI 25-29.9 kg/m2) or lean (BMI 19.5-24.9 kg/m2). Hepatic triglyceride content was quantified by 3T H1-MRS. NAFLD was defined as hepatic triglyceride content >5.56%. Insulin resistance (HOMA-IR), serum adiponectin, and tumor necrosis factor (TNF) were determined.

Results: HOMA-IR was significantly correlated with hepatic triglyceride content (r:0.76; p<0.0001). The lean-with-NAFLD group had significantly higher HOMA-IR (p<0.001) and lower serum adiponectin (p<0.05) than the overweight-without-NAFLD group. Insulin resistance was independently associated with NAFLD but not with waist circumference or BMI. Regression analysis showed hepatic triglyceride content to be the most important determinant of insulin resistance (p<0.01).

Conclusions: Our findings suggest that NAFLD, once established, seems to be involved in insulin resistance and cardio-metabolic risk factors above and beyond waist circumference and BMI in non-obese, non-diabetic Caucasian individuals.

Diagnostic accuracy of serum alanine aminotransferase as biomarker for nonalcoholic fatty liver disease and insulin resistance in healthy subjects, using 3T MR spectroscopy.

Medicine (Baltimore) 2017 Apr;96(17):e6770

Recognition of the close relationship of nonalcoholic fatty liver disease (NAFLD) with diabetes mellitus 2, obesity, metabolic syndrome, and cardiovascular disease has stimulated growing interest in NAFLD as a public health problem. Serum alanine aminotransferase (ALT) has been proposed as a marker of NAFLD, but levels are within the range currently considered "normal" in a large proportion of NAFLD subjects.The aim of the study was to determine the diagnostic accuracy of serum ALT for identifying individuals with NAFLD, using 3-Tesla (T) magnetic resonance spectroscopy (H-MRS).A cross-sectional study was conducted in 129 healthy subjects. Liver triglyceride content was quantified by H-MRS. NAFLD was defined as liver triglyceride content greater than 5.56%.Liver triglyceride content was >5.56% in 79 participants (NAFLD) and lower in the remaining 50 (normal). Serum ALT levels correlated positively with liver triglyceride content (r = 0.58, P < .001), Homeostatic Model Assessment for Insulin Resistance (r = 0.32, P < .01), and fasting insulin (r = 0.31, P < .01), and inversely correlated with adiponectin (r = 0.35, P < .01) and high-density lipoprotein cholesterol (r = 0.32, P < .01). Regression analysis showed that serum ALT was the best predictor of NAFLD (P < .01). Optimal serum ALT cut-off to predict NAFLD was 23 IU/L (area under receiver-operating characteristic curve: 0.93; sensitivity: 0.94; specificity: 0.72).This study shows that serum ALT is a sensitive and accurate biomarker of NAFLD if the "normal" ALT value is revised and established at a lower level. An ALT threshold of 23 IU/L identified 94% of individuals with NAFLD in the present series, using 3-T H-MRS for liver triglyceride quantification.
