INTRODUCTION AND OBJECTIVES: Primary biliary cholangitis (PBC) is an autoimmune liver disease, with 60% of patients being asymptomatic at diagnosis and 30% progressing rapidly into liver fibrosis. Liver biopsy is standard for staging fibrosis, but performance of non-invasive methods such as transient elastography (TE) have not been evaluated. We conducted a meta-analysis of articles up to May 2022 to evaluate the performance of TE compared with liver biopsy in adult patients with PBC.
MATERIALS AND METHODS: Two reviewers performed the search and assessed which articles were included. The quality of each study was evaluated according to QUADAS-2 and NOS. Meta-analysis of sensitivity and specificity was conducted with a bivariate random-effects model. The protocol was registered in PROSPERO, ID CRD42020199915.
RESULTS: Four studies involving 377 patients were included. Only stages F3 and F4 were computed in the meta-analysis. TE had a pooled sensitivity of 68% and specificity of 92% for stage F3 and a pooled sensitivity of 90% and specificity of 94% for stage F4. The AUROC curves were 0.91 (95% Confidence Interval (CI) 0.88-0.93) and 0.97 (95% CI 0.96-0.98) for stages F3 and F4, respectively. The mean cut-off points of TE for stage F3 were 9.28 kPa (95% CI 4.98-13.57) and for stage F4 were 15.2 kPa (95% CI 7.02-23.37).
CONCLUSIONS: TE performance compared with liver biopsy in adult patients with PBC was excellent for staging liver fibrosis and was able to rule out cirrhosis in clinical practice.
