Skin manifestations of systemic lupus erythematosus refractory to multiple treatment modalities: poor results with mycophenolate mofetil.

OBJECTIVE

Skin disease can be one of the most refractory clinical manifestations of systemic lupus erythematosus (SLE). The standard therapy consists of sunscreens, topical corticosteroids and antimalarials. However in difficult cases a variety of other drugs have been tried. Here we describe our clinical experience with mycophenolate mofetil (MMF) in patients with cutaneous manifestations of SLE.

METHODS

Seven patients with SLE and skin involvement (including acute cutaneous lupus, subacute cutaneous lupus, discoid lupus erythematosus, vasculitis, urticarial rash and chilblain lupus) who had received treatment with MMF were included. The clinical characteristics, serologicalfindings and response to treatment were recalledfrom retrospective review of the files.

RESULTS

Our results showed no response in 5 patients, partial response in 1 patient and initial response but skin flare whilst on MMF in 1 patient. The median dose of MMF was 2 g (range 2-3 g). Adverse events on MMF were mild, mainly gastrointestinal and occurred in 5 patients. No patients discontinued MMF due to adverse events.

CONCLUSIONS

MMF appears not to be particularly effective in the treatment of skin disease in SLE. It should be noted that our group of patients had previously failed to respond to a median of 4 (range 2-10) different drugs used to treat SLE skin disease. Thus, the patients in the study could be considered at the severe end of skin disease spectrum.
