Abstract

OBJECTIVE:

To compare the clinical course of patients with class III, IV and V lupus nephritis (LN) treated at Hospital Universitario Cruces (CC) and at Bordeaux University Hospital (BC).

METHODS:

The Lupus-Cruces nephritis protocol combines pulses of 125mg of methyl-prednisolone with each fortnightly pulse of cyclophosphamide and prednisone ≤30mg/day with tapering over 12-14weeks until 2.5-5mg/day. The BC followed international lupus nephritis guidelines, combining high-dose prednisone and either mycophenolate mofetil or cyclophosphamide, followed by maintenance therapy with low dose prednisone and immunosuppressive drugs. The main outcomes were complete renal remission (CR) and glucocorticoid toxicity.

RESULTS:

44 patients from BC and 29 from CC were included. The mean maximum prednisone dose was 42.5 (BC) vs. 21mg/day (CC), p<0.001. The average 6-month prednisone dose was 21 (BC) vs. 8.3mg/d (CC), p<0.001.The mean number of methyl-prednisolone pulses was 3 (BC) vs. 9.3 (CC), p<0.001. HCQ was used by 64% (BC) vs. 100% (CC), p<0.001. CR rates were 30% (BC) vs. 69% (CC), p=0.001, and 42% (BC) vs. 86% (CC), p<0.001, at 6 and 12months, respectively. Patients from the CC more frequently achieved CR (adjusted HR 3.8, 95%CI 2.05-7-09). The number of pulses of methyl-prednisolone were associated with CR (adjusted HR 1.09, 95%CI 1.03-1.15). Patients in the CC had a lower risk of GC-related side effects (adjusted HR 0.19, 95%CI 0.04-0.89).

CONCLUSION:

The Lupus-Cruces nephritis protocol improves the outcome of LN. Repeated methyl-prednisolone pulses help reduce the dose of oral glucocorticoids and enhance clinical response.
