[Systemic lupus erythematosus: news and therapeutic perspectives].

Lupus treatment has evolved considerably with spectacular advances that can be summarized in 10 points. Hydroxychloroquine and cyclophosphamide are still standard drugs, provided their use is optimized. Contraception and postmenopausal hormone replacement therapy have finally been tested in randomized studies with fairly reassuring results, although prudence remains essential in patients with severe lupus and above all in those with thrombotic complications (antiphospholipid syndrome). Mycophenolic acid has been shown to be useful in the treatment of lupus nephropathies, but its specific place in the therapeutic strategy remains to be defined. Other drugs (sirolimus, abatacept) are currently being evaluated. Anti-lymphocyte B therapies are growing in popularity. Rituximab and other drugs (anti-BAFF, TACI-Fc) are also being evaluated and their results appear very interesting. Interferon alpha (type I) inhibition is an attractive therapeutic approach in lupus but its use in humans is still premature. Peptide vaccination with fragments of autoantibodies or autoantigens is an elegant strategy, and preliminary results justify further studies. Anti-TNF molecules may be beneficial in lupus. Complement inhibition can be useful in lupus and antiphospholipid syndrome but drugs usable in humans (anti-C5) must be developed. Atheromatosis in lupus is the principal cause of morbidity and mortality and must be managed. Smoking cessation is essential, but other approaches (statins) should also be discussed. Many futuristic types of immune manipulation may be envisioned (proteasome inhibition, modulation of Fc gammaRIIB, and modulation of cell signaling (PI3kgamma)). Hence the perspectives are numerous. We will soon be able to optimize the treatment of our patients. Nevertheless, rigorous evaluation of the risk/benefit ratio of new drugs and of their most appropriate place in the therapeutic strategy against systemic lupus is indispensable.
