Popis: Abstract Introduction CHAMOMILE (CHaracteristics and impact of flares on clinicAl and econoMic OutcoMes In patients with systemic Lupus Erythematosus [SLE]) examined how flares in the year of SLE diagnosis impact future disease activity and damage, productivity, healthcare resource utilization (HCRU), and costs in patients with SLE in Germany. Methods CHAMOMILE was a retrospective cohort study of adults with an SLE diagnosis in the German Sickness Fund Database from 1 July 2010 to 31 December 2013. Patients were classified according to their greatest flare severity during the baseline year (none, mild, or moderate/severe). The number and severity of flares were assessed annually over 5–8.5 follow-up years, along with SLE organ/system damage, treatments, work disability, and HCRU metrics. Results Of 2088 patients (84.6% female; mean age [standard deviation] 51.4 [16.1] years; mean follow-up 6.8 [2.1] years), 34.3% (n = 716) were flare-free, 29.8% (n = 622) had mild flares, and 35.9% (n = 750) had moderate/severe flares at baseline. Baseline flare severity was related to future flares: rates during follow-up were higher in patients with moderate/severe baseline flares compared with those with mild or no baseline flares (89.6 vs 78.5 and 44.2 flares/100 patient years, respectively). Overall, 80.2% (n = 1675) of patients received glucocorticoids at least once during baseline and follow-up. Patients’ HCRU was generally greatest in their baseline year. Costs were highest in patients with moderate/severe baseline flares. Conclusion Baseline flare severity provided insight into a patient’s disease course and the clinical and economic burden of SLE over time, highlighting the ramifications of uncontrolled disease for patients with SLE.
