Hydroxychloroquine (HCQ) is an important medication for treating systemic lupus erythematosus (SLE). Its blood concentration (HCQ) varies widely between patients and is a marker and predictor of SLE flares. This prospective randomised, double-blind, placebo-controlled, multicentre study sought to compare standard and adjusted HCQ dosing schedules that target HCQ ≥1000 ng/ml to reduce SLE flares. HCQ was measured in 573 patients with SLE (stable disease and SELENA-SLEDAI≤12) treated with HCQ for at least 6 months. Patients with HCQ from 100 to 750 ng/ml were randomised to one of two treatment groups: no daily dose change (group 1) or increased HCQ dose to achieve the target HCQ (group 2). The primary end point was the number of patients with flares during 7 months of follow-up. Overall, mean HCQ was 918±451 ng/ml. Active SLE was less prevalent in patients with higher HCQ. A total of 171 patients were randomised and followed for 7 months. SLE flare rates were similar in the two groups (25% in group 1 vs 27.6% in group 2; p=0.7), but a significant spontaneous increase in HCQ in both groups between inclusion and randomisation strongly suggested improved treatment adherence. Patients at the therapeutic target throughout follow-up tended to have fewer flares than those with low HCQ (20.5% vs 35.1%, p=0.12). Although low HCQ is associated with higher SLE activity, adapting the HCQ dose did not reduce SLE flares over a 7-month follow-up.
