Comparison of flares in 85 patients with SLE who maintained, discontinued or reduced dose of hydroxychloroquine during a prospective study of ophthalmological screening for retinopathy (PERFOCTAPS Study).

Objective: Little is known about the risk of SLE flares associated with hydroxychloroquine (HCQ) reduction or cessation, especially after ophthalmological screening. We analysed the risk of SLE flares after HCQ reduction or discontinuation after detection of early ophthalmological toxicity.

Methods: This study includes all patients with SLE among the 109 included in the prospective PERFOCTAPS Study and treated with HCQ for at least 5 years.

Acquired haemophilia A associated to autoimmune thyroiditis and pangastritis.

Acquired haemophilia A is a rare condition defined by the presence of coagulation inhibitors, which are autoantibodies directed against factor VIII that interfere with its activity. We report a case of a 69-year-old woman that presented with knee haemarthrosis followed by spontaneous retroperitoneal haematoma. On coagulation studies, she presented normal prothrombin time with prolonged activated partial thromboplastin time non-correcting on mixture test, low titers of factor VIII and was detected factor VIII inhibitor that led to diagnosis of acquired haemophilia A.
