Abstract

Glucocorticoids are standard therapy for induction of response in proliferative lupus nephritis. However, the optimal duration of glucocorticoid therapy is uncertain. We surveyed physicians who treat lupus nephritis regarding their use of glucocorticoids in proliferative lupus nephritis after induction of response and regarding factors associated with different practice patterns. We administered a questionnaire of standardized cases assessing glucocorticoid use after induction of response to specialists with expertise in proliferative lupus nephritis. We examined the association between continuation of glucocorticoids and patient and physician characteristics. Of 90 invited participants, 72 (80%) responded. A total of 24 (33%) respondents attempted to discontinue glucocorticoids in all scenarios, 21 (29%) continued glucocorticoids in all scenarios, and 27 (38%) attempted to discontinue in some scenarios but not others. Responses varied according to the physician group (p < 0.001) and by years in practice (p < 0.001). Of those who discontinued glucocorticoids in selected scenarios, 15/27 (55%) were influenced by the characteristics of the induction of response, 16/27 (59%) by past lupus history, and 9/27 (33%) by the tolerance and use of immunosuppression. We conclude that glucocorticoid therapy after induction of response in proliferative lupus nephritis is varied. This variability likely represents clinical equipoise. A randomized trial evaluating the effect of glucocorticoid use after induction of response is warranted.
