Abstract
Background: Accumulating research has implicated that vitamin D (VD) may be important in the pathogenesis of Crohn's disease (CD), while the platelet-to-lymphocyte ratio (PLR) is emerging as a biomarker in immune disorders. However, the synergistic effect of VD and PLR on treatment escalation in newly diagnosed CD patients remains unclear. Therefore, this study aims to assess the interaction between PLR and VD on the subsequent use of infliximab and/or immunosuppressants in patients with CD.
Methods: Newly diagnosed CD patients were selected from the Sir Run Run Shaw Hospital Inflammatory Bowel Disease Biobank (SRRSH-IBC). COX proportional hazards models were employed to assess the association between VD, PLR, and treatment escalation among CD patients.
Results: Among 108 newly diagnosed CD adult patients, vitamin D deficiency (VDD) was prevalent (78.7%). Compared to CD patients without VDD, those with VDD exhibited a higher risk of treatment escalation, i.e., using infliximab and/or immunosuppressants (HR = 3.22, 95% CI = 1.24-8.35, P = 0.016). There is a clear trend of decreasing risk of treatment escalation as VD levels elevating (HR = 0.26, 95% CI = 0.09-0.76, P for trend = 0.014). The stratified analysis revealed a noteworthy interaction between PLR and VD levels concerning treatment escalation. Baseline VDD amplified the risk of treatment escalation among patients with elevated PLR (HR = 4.17, 95% CI = 1.51-11.53, Pinteraction = 0.031). Similar trends were observed when VD levels were stratified into quartiles (highest quartile vs. lowest quartile: HR = 0.18, 95% CI = 0.05-0.62, P for trend = 0.014).
Conclusion: This study underscores a significant interplay between VD levels and PLR in influencing treatment outcomes in CD. VDD exacerbates the risk of treatment escalation primarily in individuals with heightened PLR levels, highlighting the combined impact of vitamin D status and inflammation on disease progression of CD.
期刊介绍:
Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered.
Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies.
In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
