[Towards the Swiss systemic lupus erythematosus cohort study (SSCS)].

Systemic lupus erythematosus (SLE) is a rare disease mainly affecting women of childbearing age. It is characterized by a very large spectrum of clinical manifestations accompanied by prototypic abnormalities of the immune system. While recent advances in therapeutic approaches have taken place, SLE still has a profound impact on the quality of life and life expectancy of affected persons.

Marked erythrocyte microcytosis under primary immunosuppression with sirolimus.

The preliminary observation of marked erythrocyte microcytosis in patients treated with sirolimus (SRL) and mycophenolate mofetil (MMF) has been evaluated as part of a prospective study comparing SRL and cyclosporin A (CsA) as a primary immunosuppressant. Normal risk de novo kidney recipients were randomized either to SRL or to CsA. Additional immunosuppressants consisted of MMF and prednisone.
