dc.description.abstract
The importance of nonalcoholic fatty liver disease (NAFLD) and its relation with metabolic syndrome is now increasingly recognized as recent data suggest NAFLD predicts more accurately insulin resistance than ATP III criteria . Additionally, NAFLD is linked to increased cardiovascular risk and endothelial dysfunction, being fatty liver an independent predictor of increased intima-media thickness . Plasma ICAM-1 levels (sICAM-1) are elevated in atherosclerotic syndromes and have been associated with endothelial dysfunction. sICAM-1 (Diaclone, France) were measured in 118 NAFLD patients with different stages of disease severity (32/86 males/females), and a group of 55 healthy individuals (22/33 males/females); mean ± SD age: 52.5±12.1 years. A liver biopsy was performed in 79 patients that showed persistently abnormal liver function tests; liver specimens were scored according to the system developed by Brunt et al. Fatty liver (FL) with persistently normal liver function tests was observed in 39 subjects, FL with persistently abnormal liver function test in 26 subjects and nonalcoholic steatohepatitis (NASH) with evidence of fibrosis and liver cell injury in 53 patients. Patients had most of the features of metabolic syndrome, including high values of homeostatic model assessment index (HOMA). sICAM-1 levels were significantly higher in NAFLD patients (584.4±182.1, p<1x10-6) in comparison with controls. In addition, there was a markedly significant difference among NAFLD groups, the lowest levels in normal subjects (356.5±309.5) and the highest levels in patients with NASH (650.2±44.9) with intermediate levels in patients with less severe FL disease (496.1±46.1 and 553.7±50.5, respectively), p=0.0002, ANCOVA with HOMA as a covariate. Then, a 12.5% of the sICAM-1 total variance was explained by FL disease gradation. Besides, for each 100 units of sICAM-1, OR for NAFLD was 1.36 (95 %CI 1.11-1.61, p=0.0043) independently of HOMA index. A graded positive relationship between NAFLD stages and sICAM-1 levels independently of sex, BMI, aspartate aminotransferase and HOMA was observed. In conclusion, our findings suggest that NAFLD severity is associated with sICAM-1 levels; NASH patients had the higher sICAM-1 concentrations. Additionally, sICAM-1 level predicts NAFLD stages independently of potential confounders. To date, there are not recommended noninvasive tests for evaluation of NAFLD histologic spectrum, and a complete diagnosis of the disease should include the stage and grade of the disease severity. The ideal test is either a single or multi-marker approach to distinguish not only NASH from FL, but also to estimate the extent of liver fibrosis and monitoring response to therapy (4). Traditionally, the disease severity is evaluated by liver biopsy, which is mostly indicated when patients show abnormal aminotransferases. Paradoxically, it was previously shown that liver function test are not useful enough to distinguish NAFLD stages, and the sensitivity for NASH diagnosis was poor, at about 40%. Our findings, even though observed in a small study but with the strength of having most of the patients with NAFLD diagnosis based on liver biopsy, show that sICAM-1 levels could potentially be used as a noninvasive diagnostic test to predict the severity of NAFLD with the plus of being a proven marker of preclinical atherosclerosis.
