  1. Whooping cough and Parkinson's disease.

    Article - En anglais

    Background

    We reported high levodopa use and prevalences of Parkinson's Disease (PD) in periodically, time-clustered, Icelandic cohorts born after major whooping cough epidemics (MWCE).

    Methods

    In order to quantify a possible relationship between age at first post-birth MWCE and risk of PD we : 1) calculated cumulative incidences of PD during the period 1954-1963 in one-year Icelandic cohorts born between 1869 and 1927, using raw material from a reported survey ; 2) identified MWCE from 1869 onwards in Iceland ; 3) estimated cohort ages at onset of incidence period and at first MWCE ; and 4) combined the above-mentioned information using log-linear models.

    In addition, we studied the prevalence of levodopa users in Icelandic birth cohorts during a recent period.

    Results

    The curves of the above-mentioned incidences and prevalences in one-year birth-cohorts showed : 1) a similar, age-related, inverted V profile ; and 2) a systematic notchy pattern, with peak values for one or both measurements for cohorts born during or after each of nine MWCE identified during the period 1869-1927.

    When 13 cohorts born in years with MWCE were excluded from the analysis, the risk of PD rose with age at first defined MWCE, with the linear increase being 8.4% per year (95% CI : - 0.1-18.3%). Conclusions. (...)
