Abstract
BACKGROUND

The relationship between copeptin and the severity of circulatory dysfunction and systemic stress response in patients with chronic liver disease (CLD) has been established. Nevertheless, the potential of serum copeptin levels to predict the prognosis of CLD patients remains unclear.

AIM

To conduct a systematic review and meta-analysis to investigate the correlation between serum copeptin and transplant-free survival (TFS) in this population.

METHODS

To achieve the objective of the meta-analysis, PubMed, Embase, the Cochrane Library, and the Web of Science were searched to identify observational studies with longitudinal follow-up. The Cochrane Q test was utilized to assess between-study heterogeneity, and the I2 statistic was estimated. Random-effects models were employed to combine the outcomes, taking into account the potential influence of heterogeneity.

RESULTS

Ten datasets including 3133 patients were involved. The follow-up durations were 1 to 48 mo (mean: 12.5 mo). Overall, it was shown that a high level of serum copeptin was associated with a poor TFS [risk ratio (RR): 1.82, 95% confidence interval: 1.52-2.19, P < 0.001; I2 = 0%]. In addition, sensitivity analysis by omitting one dataset at a time showed consistent results (RR: 1.73-2.00, P < 0.05). Finally, subgroup analyses according to study country, study design, patient diagnosis, cutoff of copeptin, follow-up duration, and study quality score also showed similar results (P for subgroup difference all > 0.05).

CONCLUSION

Patients with CLD who have high serum copeptin concentrations may be associated with a poor clinical prognosis.

Core Tip: Serum copeptin has been related to the severity of circulatory dysfunction and systemic stress response in patients with chronic liver disease (CLD). However, little is known about the relationship between serum copeptin and the prognosis of patients with CLD. In this systematic review and meta-analysis, evidence from ten datasets including 3133 patients were integrated. The results showed that a high level of serum copeptin was associated with a poor transplant-free survival in these patients. These findings support the use of serum copeptin as a prognostic biomarker for patients with CLD.
