  1. Absence of an association of rheumatoid arthritis and diffuse idiopathic skeletal hyperostosis : a case-control study.

    Article - En anglais

    Objective

    To compare the frequency of diffuse idiopathic skeletal hyperostosis (DISH), based on an evaluation of chest radiographs, in 2 populations of patients : those with and without rheumatoid arthritis (RA).

    Methods

    Cases of RA were obtained from the Wichita Arthritis Center databank and controls from a private cardiology practice.

    Analyses were conducted to take into account the sensitivity and specificity of chest radiographs for the diagnosis of DISH.

    Results

    Among 748 radiographs (357 RA and 391 controls), 29 were diagnosed as DISH (21 controls and 8 RA).

    The mean age for the RA group was 66.2 yrs (SD=11.9) and 108 (30.2%) were men.

    Control subjects had a mean age of 69.6 yrs (SD=11.4) and 138 (35.4%) were men.

    The DISH patients, compared with those without DISH, were more likely to be male (p=0.004) and older (p<0.001).

    After accounting for age and sex, the relative risk of DISH in RA versus the controls was 0.40 (95% confidence interval : 0.20 to 1.01).

    After taking into account the sensitivity and specificity in this population, the adjusted prevalence of DISH for the RA group was 1% (95% confidence interval : 0.1 to 3.7) and 3.1% (95% confidence interval : 0.2 to 7.9) for the control group.

    Conclusion

    We confirmed the increase in frequency of DISH with increasing age and male sex, but failed to support an increased association of DISH with RA.
