An erratum to this article was published (Lupus Sci Med, 20 Apr 2025 ↗)
Authors' conclusion
With the use of HCQ at stable doses of 200 mg/day (or 3.0-3.5 mg/kg/day) as the background therapy in patients with systemic lupus erythematosus, the majority of patients achieved prolonged remission.
Study context
- Population
- Inception patients with SLE treated with hydroxychloroquine (HCQ) with at least 5 years of follow-up, Lupus-Cruces cohort
- Participants
- 150 inception patients
- Exposure
- Weight-adjusted HCQ dose in patients with vs without prolonged remission
- Prolonged remissionn = 108
- Outcome
- Association between weight-adjusted HCQ dose during 5 years and prolonged remission
- Follow-up
- 5 years
Methodological detailsinception cohort, routine clinical care data
- Inception cohort
- Routine clinical care data
