New insights about the following aspects of lupus erythematosus are developed: (1) thrombotic and neurological manifestations associated with the presence of antiphospholipid antibodies; (2) cardiac complications, especially coronary ischemia, conduction abnormalities and valvular involvement; (3) pregnancy, with particular attention to fetal and maternal prognoses, Soulier-Boffa syndrome and congenital atrioventricular heart blocks; (4) subacute lupus erythematosus, bullous lupus and cutaneous manifestations associated with the lupus anticoagulant.
