Abstract

fetched live from OpenAlex

Abstract Background In HCV-infected patients with advanced liver disease, the direct antiviral agents (DAAS)-associated clinical benefits remain debated. We compared the clinical outcome of patients with a previous history of decompensated cirrhosis following treatment or not with DAAs from the French ANRS CO22 HEPATHER cohort. Methods We identified HCV patients who had experienced an episode of decompensated cirrhosis. Study outcomes were all-cause mortality, liver-related or non-liver-related deaths, hepatocellular carcinoma, liver transplantation. Secondary study outcomes were sustained virological response (SVR) and its clinical benefits Results 559 patients met the identification criteria, of which 483 received DAA and 76 remained untreated after inclusion in the cohort. The median follow-up time was 39·7 (IQR: 22·7–51) months. After adjustment for multivariate analysis, exposure to DAAs was associated with a decrease in all-cause mortality (HR 0·45, 95% CI 0·24–0·84, p = 0·01) and non-liver-related death (HR 0·26, 95% CI 0·08–0·82, p = 0·02), and was not associated with liver-related death, decrease in hepatocellular carcinoma and need for liver transplantation. The SVR was 88%. According to adjusted multivariable analysis, SVR achievement was associated with a decrease in all-cause mortality (HR 0·29, 95% CI 0·15–0·54, p < 0·0001), liver-related mortality (HR 0·40, 95% CI 0·17–0·96, p = 0·04), non-liver-related mortality (HR 0·17, 95% CI 0·06–0·49, p = 0.001), liver transplantation (HR 0·17, 95% CI 0·05–0·54, p = 0.003), and hepatocellular carcinoma (HR 0·52, 95% CI 0·29–0·93, p = 0·03). Conclusion Treatment with DAAS is associated with reduced risk for mortality. Thus, DAA treatment should be considered for any patient with HCV-related decompensated cirrhosis.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
