Organ Damage and Quality of Life in Antiphospholipid Syndrome.

Antiphospholipid syndrome (APS) affects young patients in the most productive years of their life, and the consequences of organic or tissue damage involve a decrease in health-related quality of life (HRQoL). While acute disease manifestations of APS are well known, information on the long-term prognosis and damage in affected patients is still very limited. Systemic lupus erythematosus (SLE) patients would be expected to experience long-term complications and even die as a consequence of APS. Organ damage in APS has been evaluated using different methods and definitions, including the SLICC/ACR Damage Index (SDI), which tend to underestimate aPL-related damage. A new damage index in APS has been proposed (DIAPS), and it seems to be more accurate than SDI. Given the implications for morbidity and mortality, it is imperative to assess accurately aPL-related damage and HRQoL in patients with APS.
