Aims
To examine the relationship between plasma levels of the acute-phase proteins ceruloplasmin, alpha-1-antitrypsin, orosomucoid, haptoglobin and C-reactive protein (CRP), and incidence of diabetes in the population-based Malmö Diet and Cancer Study—Cardiovascular Cohort (MDCS-CC).
Methods
The study population consists of 4246 participants (aged 46–67 years, 60.8 % women) with no previous history of diabetes. Participants were followed, and incidence of diabetes was assessed by linkage with national registers and a clinical re-examination of the cohort. Cox proportional hazard regression analysis was used to compare incidence of diabetes in relation to sex-specific quartiles of the acute-phase proteins.
Results
During a mean follow-up period of 15.6 ± 3.4 years, a total of 390 participants were diagnosed with diabetes. Orosomucoid, haptoglobin, and CRP showed a significant increased risk of diabetes after adjustment for potential confounders. However, further adjustments for fasting glucose at baseline resulted in significant association only for CRP. The multivariable-adjusted hazard ratios (HR: 4th vs. 1st quartile) were 1.18 (95 % CI: 0.83–1.67; p = 0.51), 1.19 (CI: 0.85–1.62; p = 0.10), and 1.40 (CI: 1.01–1.95; p = 0.046) for orosomucoid, haptoglobin, and CRP respectively.
Conclusion
The study demonstrated that there are associations between orosomucoid, haptoglobin and CRP and the risk of incidence of diabetes. However, after additional adjustment for fasting glucose levels at baseline, the association stayed significant only for CRP.
