THE PERFORMANCE OF GPRI, FIB-4 AND LIVER ELASTOGRAPHY FOR DIAGNOSING LIVER FIBROSIS IN PATIENTS WITH CHRONIC HEPATITIS B

After assessing liver fibrosis stages of 83 patients with chronic hepatitis B using GPRI, FIB-4 and ElastPQ, we have the following conclusions: GPRI had a good accuracy for diagnosing significant liver fibrosis and advanced fibrosis with AUROC > 0.7. With a cut-off of 0,38, GPRI had a high sensitivity and NPV for diagnosing significant fibrosis (> 80%). With a cuf-off of 0,59, GPRI had a very high sensitivity and NPV for diagnosing advanced fibrosis  (> 90%). FIB-4 had sub-optimal accuracy for diagnosing significant fibrosis with AUROC of 0,64 and advanced fibrosis with AUROC of 0,65. With a cut-off of 2,34 for diagnosing significant fibrosis (≥F2): FIB-4 had very high specificity (92%), and NPV of 65%. With a cut-off of 2,65 for diagnosing advanced fibrosis (≥ F3): FIB-4 had a very high specificity and and also a very high NPV (>80%). ElastPQ had excellent accuracy for diagnosing both significant and advanced fibrosis (AUROC was 0,84 and 0,83, respectively). For diagnosing significant fibrosis: with cut-off of 6.07, ElastPQ had sensitivity of 86%, specificity 71%, PPV 68% and NPV 87%; For diagnosing advanced fibrosis: using cut-off of 9,43, ElastPQ had sensitivity of 67%, specificity 97%, PPV 87% and NPV 90% All 3 tools GPRI, FIB-4 and ElastPQ had significant positive correlation with liver fibrosis stage (p < 0,001). Among them, liver elastography using ElastPQ had the strongest correlation (r = 0,62, p < 0,001).
