Abstract

Background Current guidelines advocate a step-wise approach to disease-modifying treatment of primary biliary cholangitis (PBC): all patients begin treatment with ursodeoxycholic acid (UDCA) monotherapy – and those with inadequate biochemical response to UDCA are subsequently considered for second-line therapies, the conventional period to demonstrate inadequate UDCA response being 12 months. A potential limitation with this approach, however, is that patients at highest risk end up waiting longest for effective treatment. In this study, we sought to determine whether UDCA response can be accurately predicted using pre-treatment clinical parameters, so that alternative approaches to treatment stratification might be explored. Methods We undertook logistic regression analysis of pre-treatment variables in 2,703 UDCA-treated patients to derive the best-fitting model of UDCA response, defined as ALPT12 < 1.67×ULN. We validated the model in an external PBC cohort from Italy (n=460). Finally, we explored the biological plausibility of the model by looking for correlation between model predictions and key histological features on PBC liver biopsies (n = 20), such as biliary injury and fibrosis. Findings The following pre-treatment parameters were associated with lower probability of UDCA response: higher ALP (p<0.0001), higher bilirubin (p=0.0003), lower transaminases (TA, p=0.0012), younger age (p<0.0001), longer interval from diagnosis to the start of UDCA (treatment time lag, p<0.0001), and worsening of ALP from diagnosis (ΔALP, p<0.0001). Based on these variables, we derived a predictive score of UDCA response: UDCAresponsescore(URS)=0.77+0.60×(TBdiag)−1−2.73×ln(ALPdiag)+0.35×ln(TAdiag)+0.03×age−0.15×(treatmenttimelag)−0.56×ΔALP In external validation, the AUROC was 0.83 (0.79-0.87). In PBC liver biopsies, the URS was associated with ductular reaction (DR) and intermediate hepatocytes (IH). Interpretation We have derived and externally validated a model based on pre-treatment variables that accurately predicts UDCA response. Association with DR and IH provides face validity. Thus, this model provides a basis to explore alternative approaches to treatment stratification in PBC. Fundings Medical Research Council (MR/L001489/1); University of Milan-Bicocca.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
