Glucocorticoid discontinuation in patients with SLE with prior severe organ involvement: a single-center...

Long-term glucocorticoid use in SLE may have significant side effects; however, glucocorticoid discontinuation is occasionally associated with disease flare-ups. Therefore, we evaluated the risk factors for disease flares and the flare rate on glucocorticoid tapering in patients with prior severe organ involvement.

Data of patients with SLE with glucocorticoid tapering at our institution were retrospectively analysed. We divided the patients by the presence of prior severe organ involvement and compared flare rates after glucocorticoid discontinuation. Furthermore, we determined risk factors for flares after glucocorticoid discontinuation.

In total, 309 patients with SLE were screened, 73 of whom met the inclusion criteria; 49 were classified as SLE with prior severe organ involvement. No significant differences were noted in the 52-week flare rate after glucocorticoid discontinuation between patients with and without prior severe organ involvement (16.7% vs 18.2%, p=1.0). Hypocomplementaemia, elevated anti-dsDNA antibody titres more than twice the upper limit of the laboratory reference range, positive anti-Smith/anti-ribonucleoprotein antibody, and use of any immunosuppressant on the day of glucocorticoid discontinuation were negatively associated with flare-free remission.

Glucocorticoid discontinuation after gradual tapering can often be achieved in patients with SLE, even with prior severe organ involvement, especially when the disease is clinically and serologically stable.
