    Abstract:
    OBJECTIVE: To analyze the influence of 2 different treatment strategies on general and specific damage accrual in patients with systemic lupus erythematosus (SLE). METHODS: Two cohorts were identified according to the responsible physicians: patients treated at the autoimmune diseases unit (ADU), and patients treated by other members of the internal medicine (IM) department. Members of the ADU worked with a protocol including the universal prescription of hydroxychloroquine (HCQ), the use of maximum oral prednisone dosages ≤30 mg/day and maintenance therapy with ≤5 mg/day, by using methylprednisolone pulses and/or early immunosuppressive (IS) drugs. We analyzed the influence of these 2 treatment strategies on damage accrual, both general and domain specific, attributed to glucocorticoids, cardiovascular (CV) disease, SLE, and unclassified, since the diagnosis of disease in patients with a followup ≥5 years. RESULTS: A total of 74 patients were included in the ADU group and 213 in the IM group. They were comparable for most demographic and lupus-related variables. ADU patients received prednisone later and at lower doses, more methylprednisolone pulses, earlier IS drugs and more HCQ (P < 0.05 for all comparisons). The Systemic Lupus Erythematosus Disease Activity Index score decreased similarly in both cohorts (P = 0.4). Patients in the ADU group were less likely to accrue any damage (P = 0.007). They accrued less glucocorticoid-related (adjusted hazard ratio [HR] 0.23 [95% confidence interval (95% CI) 0.07-0.80]), CV disease (adjusted HR 0.28 [95% CI 0.08-0.95]), and unclassified damage (adjusted HR 0.58 [95% CI 0.3-1.1]). Both groups accrued similar SLE-related damage (adjusted HR 0.84 [95% CI 0.40-1.75]). CONCLUSION: The use of reduced oral prednisone doses, which was possible by combining different therapies, reduced glucocorticoid-related damage and improved CV prognosis without increasing damage caused by SLE.
