KEY POINTS: The contribution of IV methylprednisolone to glucocorticoid toxicity is often overlooked with limited evidence supporting its use. Markedly reduced cumulative glucocorticoid dosing for remission induction therapy in AAV is safe and effective. Reduced IV methylprednisolone and radical steroid avoidance strategies have not been shown to have any significant adverse effect on outcomes.
BACKGROUND: Glucocorticoids (GCs) remain integral to the management of ANCA-associated vasculitis (AAV), but are associated with significant adverse effects. Recent studies have shown reduced oral GC dosing to be safe and effective; however, data guiding the use of intravenous (IV) methylprednisolone (MTP) are limited.
METHOD: A single-center retrospective cohort of patients with AAV were divided into two groups: low-dose GC (patients receiving 250 mg of IV MTP, followed by a tapering course of 30 mg of prednisolone daily) versus high-dose GC (1.5 g of IV MTP, followed by a tapering course of 40–60 mg of prednisolone daily). Primary outcomes included ESKD and mortality, and secondary outcomes included GC-related toxicity, remission, and relapse rates. This study was applied to patients with newly diagnosed AAV, including those with severe or life-threatening disease.
RESULTS: Sixty-five patients were included in the final analysis—34 in the high-dose treatment group and 31 in the low-dose treatment group. At diagnosis, more advanced renal impairment and histological disease were present in the low-dose cohort. The rate of ESKD was similar between the groups at 6 and 12 months (P = 0.22, P = 0.60, respectively). More deaths occurred in the high-dose group (26.5% versus 6.5%, P = 0.05), although this was not significant on multivariable analysis (P = 0.06). Remission rates were comparable, and there was no significant difference in relapses. Adverse events were seen in both groups, but patients in the high-dose group experienced a higher incidence of severe infections, weight gain, and steroid-induced diabetes.
CONCLUSION: We demonstrate that a markedly reduced dose of IV MTP with a lower overall cumulative dose of GCs is safe and effective in the management of severe AAV disease, with no significant difference in primary outcomes.
