Abstract

Background and aims: The relationship between serum albumin levels and therapeutic outcomes in ulcerative colitis (UC) has been debated. Additionally, the dynamic changes in albumin levels remain understudied.

Methods: We conducted a pooled analysis of five clinical trials involving 3,268 patients with UC. Short- and long-term therapeutic outcomes were assessed at the end of the induction and maintenance phases. Multivariate logistic regression and random effects models were used to pool the predictive effects of albumin levels. The dynamic trajectory of albumin was fitted using latent class growth mixed models.

Results: Baseline and week-2 albumin were independent predictors of short-term outcomes, with pooled adjusted odds ratios (aORs) [95% confidence intervals (CIs)] of 1.07 [1.05-1.09] and 1.11 [1.08-1.15] per 1 g/L increase for clinical response, respectively. Higher post-induction albumin levels predicted better long-term outcomes, including clinical (aOR [95% CI]: 1.16 [1.12-1.21]), endoscopic (1.13 [1.10-1.16]) and histological remission (1.11 [1.03-1.18]). Furthermore, there are three classes of albumin trajectories: sustained medium-to-high, rapidly ascending and poor response. Compared to the sustained medium-to-high class, patients in the poor response class had a lower probability of long-term endoscopic remission (aOR 0.35 [95% CI: 0.23-0.50]; P<0.001), while no significant difference was observed between the rapidly ascending class and the sustained medium-to-high class.

Conclusion: Higher albumin levels were associated with better therapeutic outcomes in patients with UC. However, patients with low but rapidly ascending albumin levels would achieve outcomes comparable to those with medium-to-high levels of albumin.

期刊介绍: Clinical Gastroenterology and Hepatology (CGH) is dedicated to offering readers a comprehensive exploration of themes in clinical gastroenterology and hepatology. Encompassing diagnostic, endoscopic, interventional, and therapeutic advances, the journal covers areas such as cancer, inflammatory diseases, functional gastrointestinal disorders, nutrition, absorption, and secretion. As a peer-reviewed publication, CGH features original articles and scholarly reviews, ensuring immediate relevance to the practice of gastroenterology and hepatology. Beyond peer-reviewed content, the journal includes invited key reviews and articles on endoscopy/practice-based technology, health-care policy, and practice management. Multimedia elements, including images, video abstracts, and podcasts, enhance the reader's experience. CGH remains actively engaged with its audience through updates and commentary shared via platforms such as Facebook and Twitter.
