    Article - En anglais

    Objective

    To determine the incidence, prevalence, and survival of polymyalgia rheumatica (PMR) over a 22-year period in Olmsted County, Minnesota.

    Methods

    Using the unified record system at the Mayo Clinic for the Olmsted County population, we reviewed all medical records with a diagnosis of PMR from 1970 through 1991.

    Results

    There were 245 (173 female ; 72 male) incidence cases of PMR between 1970 and 1991.

    The average annual age-and sex-adjusted incidence of PMR per 100,000 population =50 years was 52.5 (95% confidence interval [CI] 45.9-59.2), with a significantly higher incidence in females (61.7 ; 95% CI 52.3-71.2) than in males (39.9 ; 95% CI 30.7-49.2).

    The incidence varied over the period of observation, but no significant trends were found.

    The prevalence of PMR among persons =50 years on January 1,1992 was 6/1,000.

    There was a small but significantly increased survival rate among male PMR patients compared with the general population.

    Conclusion

    Our data demonstrate that PMR is a common nonfatal disease in the elderly, the incidence and clinical manifestations of which have varied but remained relatively stable over the last 2 decades.
