Lupus in adolescence.

Juvenile systemic lupus erythematosus (JSLE) represents 15-20% of all SLE cases. The leading presenting symptoms of JSLE are constitutional and not specific such as fatigue, headache, weight loss or mood swings. They are also encountered in healthy adolescents, which explains frequent diagnosis delay. The frequency of irreversible damage is high in JSLE and involves especially the renal, musculoskeletal and neuropsychiatric systems. Although the overall prognosis has markedly improved, thanks to earlier diagnosis and new therapeutic approaches, cardiovascular, hematological events and chronic renal failure remain severe, and constitute the main disease-related causes of death. Treatment is based on hydroxycloroquine and corticosteroids. Immunosuppressive agents must be discussed to decrease the duration of corticosteroids use. New drugs and monoclonal antibodies targeting B-cells and B-cell related cytokines are being evaluated with encouraging results. Management of JSLE has to challenge three objectives: controlling disease progression, obtaining patient's adherence to treatment, and preventing consequences of medication side effects on growth, puberty, development and fertility. Patients' quality of life and psychosocial development have also to be taken into account, as well as the organization of a successful transition from paediatric to adult care.
