Nash Crn Fibrosis Score. The pro-fibrotic microenvironment seen in NASH could be explained by

The pro-fibrotic microenvironment seen in NASH could be explained by complex interactions of parenchymal and non-parenchymal cells which drive and perpetuate NASH progression. Results: (i) Development. However, the generalizability of this new scoring system to a community setting has not been evaluated. The fibrosis component is staged similarly as in the NASH CRN system; the inclusion of fibrosis in the SAF score presents a snapshot of the patient’s disease status. 25 Based on the analysis of several sets of biopsies, steatosis, lobular Sponsors can enroll patients based on 122 either a known histological diagnosis of NASH or a combination of biochemical criteria 123 and/or imaging evidence of steatosis/steatohepatitis/fibrosis Hepatocellular injury and inflammation are believed to be the primary drivers of fibrogenesis that ultimately lead to cirrhosis in patients with NASH. The NASH CRN scheme evaluates patterns of fibrosis which do not necessarily have a linear relationship to the amount of pathologic collagen deposition (fibrosis). 17.

This score consists of 3 lab values that are widely available outside of specialized hepatology clinics. The NASH CRN scoring system is seen in Table 4 [4], which provides a NAFLD activity score based upon steatosis grade, degree of lobular inflammation and hepatocellular ballooning, and fibrosis score. In contrast to differences in the concepts of activity and the scoring of the features of ballooning and lobular inflammation, the scoring of fibrosis is the same in both NASH CRN and FLIP SAF (except for the subclassification of F1 in NASH CRN). The score ranges from -1. Till date, liver biopsy remains the gold standard for identification and quantification of the wide histological spectra of NAFLD.
