Incident use of hydroxychloroquine for the treatment of rheumatoid arthritis and systemic lupus erythematosus during the COVID-19 pandemic

OBJECTIVE: We studied whether the use of hydroxychloroquine (HCQ) for COVID-19 resulted in supply shortages for patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE).
METHODS: We used US claims data (IQVIA PHARMETRICS® Plus for Academics [PHARMETRICS]) and hospital electronic records from Spain (IMASIS) to estimate monthly rates of HCQ use between January 2019 and March 2022, in the general population, and in RA and SLE patients. Methotrexate (MTX) was use was estimated as a control.
RESULTS: Over 13.5 million individuals (13,311,811 PHARMETRICS, 207,646 IMASIS) were included in the general population cohort. RA and SLE cohorts enrolled 135,259 and 39,295 patients respectively, in PHARMETRICS. Incidence of MTX and HCQ were stable before March 2020. On March 2020, the incidence of HCQ increased by 9- and 67-fold in PHARMETRICS and IMASIS respectively, to decrease in May 2020. Usage rates of HCQ went back to pre-pandemic trends in Spain, but remained high in the US, mimicking waves of COVID-19. No significant changes in HCQ use were noted among patients with RA and SLE. MTX use rates decreased during HCQ approval period for COVID-19 treatment.
CONCLUSIONS: Use of HCQ increased dramatically in the general population in both Spain and the US during March and April 2020. While Spain returned to pre-pandemic rates after the first wave, use of HCQ remained high and followed waves of COVID-19 in the US. However, we found no evidence of general shortages in the use of HCQ for both RA and SLE in the US. This article is protected by copyright. All rights reserved.
