<b>Background</b>: Non-invasive prediction of significant liver fibrosis and gastro-esophageal varices during mass treatment for HCV is crucial.The aim is to validate the accuracy of FIB-4 & APRI for predicting significant fibrosis in chronic HCV patients during mass treatment with directly acting anti-viral agents (DAAs) & their validity for predicting varices.<b>Methods</b>: We did a search in a database of 21,617 patients with chronic HCV infection recruited to one of the national HCV treatment centers to find out those with fibrosis assessment by recent liver biopsies &/or liver stiffness to serve as a gold standard.
<b>Methods:</b> From December 2016 to April 2018, all participants with chronic hepatitis C infection (CHC) were offered liver fibrosis evaluation at the Stockholm NEP, including liver stiffness measurement (LSM), a medical history and expanded blood tests to evaluate APRI and FIB-4 scores.
<b>Objectives:</b> To validate the usefulness of a hepatic fibrosis scoring system fibrosis-4 (FIB-4) index to diagnose liver diseases in rheumatoid arthritis (RA) patients treated with methotrexate (MTX).<b>Methods:</b> The FIB-4 index (age(years) × AST(U/L)/platelet (PLT) (10<sup>9</sup>/L) × √ALT(U/L)), proposed as a predictor for liver fibrosis in HIV/HCV coinfection, was evaluated in this study.
Liver fibrosis was assessed using the fibrosis-4 index (FIB-4) [age (years)× aspartate aminotransferase level (IU/L)/platelet count (10<sup>9</sup>/L)/√alanine aminotransferase (IU/L)].
FIB-4, APRI and red cell volume distribution width-to-platelet ratio (RPR) had similar diagnostic values in discriminating different levels of liver fibrosis.
A further longitudinal analysis was performed in the population of HIV/HCV-co-infected free from SLE with FIB-4 index < 3.25 at baseline, using the following endpoints: (A) first event between SLE and LRD; (B) liver fibrosis progression defined as the first of two consecutive FIB-4 > 3.25; (C) first event between SLE, LRD, and liver fibrosis progression.
A simple non-invasive score (Fibrofast, FIB-5) was developed using five routine laboratory tests (ALT, AST, alkaline phosphatase, albumin and platelets count) for the detection of significant hepatic fibrosis in patients with chronic hepatitis C. The FIB-4 index is a non-invasive test for the assessment of liver fibrosis, and a score of ≤1.45 enables the correct identification of patients who have non-significant (F0-1) from significant fibrosis (F2-4), and could avoid liver biopsy.
AAR, LPR, LMR, IGPR, APRI, and FIB-4 were linked to liver fibrosis-stage (P < 0.05), with correlation indices of - 0.219, 0.258, - 0.149, 0.647, 0.841, and 0.704, respectively, but not LNR (P = 0.093). area under the receiver operating characteristic curves of LPR, IGPR, AAR, LMR, APRI, and FIB-4 for detecting cirrhosis (F4 vs. F0-F3) were 0.936 (95% confidence interval: 0.870-1.000, P < 0.001), 0.939 (0.875-1.000, P < 0.001), 0.528 (0.319-0.738, P = 0.768), 0.555 (0.409-0.700, P = 0.568), 0.798 (0.694-0.902, P = 0.002), and 0.881 (0.796-0.967, P < 0.001).
According to histopathology, liver fibrosis was METAVIR F0 in 2 (2.0%), F1 in 43 (42.6%), F2 in 34 (33.7%), F3 in 16 (15.8%), and F4 in 6 (5.9%) patients, and was correlated with ARFI (p = 0.0001), APRI (p = 0.012), and FIB-4 (p = 0.004).
Although Metavir and Fibrosis-4 (FIB-4) scores are typically used to assess the severity of liver fibrosis, the relationship between these scores and patient outcome in hepatocellular carcinoma (HCC) is unclear.
APRI and FIB-4 values decreased significantly during 5-year ETV treatment in HBeAg-negative CHB patients, indicating that these noninvasive fibrosis tests might be useful for monitoring improvement in liver fibrosis and assessing treatment efficacy during long-term ETV treatment.
APRI, FIB-4, CDS, King score, and GUCI had intermediate accuracy in predicting significant liver fibrosis with AUROC 0.68, 0.78, 0.74, 0.74, and 0.67, respectively, while AAR had low accuracy in predicting significant liver fibrosis.
ARFI elastography is a reliable method for non-invasive staging of liver fibrosis in CHC patients when compared to TE with a good diagnostic performance comparable to FIB-4 and APRI scores for the prediction of significant fibrosis and cirrhosis.
Aspartate aminotransferase to platelet ratio index, FIB-4 and gamma-glutamyl transpeptidase to platelet ratio had good diagnostic properties to detect liver fibrosis and cirrhosis in patients with chronic hepatitis B in East Africa.
CEI was significantly lower in patients with than without hyperbilirubinemia (P = .009), but there were no significant differences between the 2 groups in pretreatment serum albumin concentrations and FIB-4 index, an index of liver fibrosis.
