Burden of Recurrent Pericarditis on Health-Related Quality of Life.

The extent to which recurrences of pericarditis episodes impact patients' health-related quality of life (HRQOL) remains poorly understood. This study aimed to evaluate HRQOL and work productivity in patients with recurrent pericarditis (RP). Adult patients from a centralized recruitment database for the rilonacept Phase 2/3 clinical trials were invited to participate in a survey. Inclusion criteria were confirmed RP diagnosis and ≥1 recurrence within the previous 12 months. The 11-Point Pain Numeric Rating Scale, Patient Global Impression of Pericarditis Severity, Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health v1.2, PROMIS Short Form Sleep Disturbance 8b, Work Productivity and Activity Impairment v2.0, and customized questions about fear and economic impact were used. In total, 83 patients (55% female, average age = 49.3 years) completed the survey. The median time since pericarditis diagnosis was 3.0 years at the time of survey completion; 49% experienced ≥3 recurrences in the previous 12 months. Forty percent had an emergency room visit, and 25% were hospitalized for their most recent recurrence. Sixty-six percent of participants rated the symptoms of their last recurrence as severe. The mean value for worst pericarditis pain (0 to 10 scale) during the most recent recurrence was 6.1. The average T-scores for PROMIS physical and mental health were 37.6 and 42.8, respectively, compared with 50 in the general population. Participants reported 50% of overall work impairment and 62% of activity impairment due to RP. In conclusion, patients with RP experienced a high number of recurrences with severe symptoms that substantially reduced their HRQOL and work productivity.
