The catastrophic antiphospholipid syndrome (CAPS) is a rare life-threatening clinical condition that represents the most severe clinical presentation of the antiphospholipid syndrome (APS). It was first described in 1992 in a group of patients that presented with multiorgan involvement and microangiopathic features of APS. ⋯ The analysis of cases included in the "CAPS Registry" has shown that the triple therapy with anticoagulation, glucocorticoids, and plasma exchange and/or intravenous immunoglobulins is associated to a better prognosis of CAPS. The improvement of the knowledge allowed a decrease from the 50% mortality rate reported in the first series to 25-30% in the most recent publications.

Thrombotic manifestations, mainly venous thromboembolism (VTE) and stroke, are the most common and potentially life-threatening presentations of antiphospholipid syndrome (APS). The management of APS requires the assessment of the antiphospholipid antibodies (aPL) profile, of concurrent systemic lupus erythematosus or other systemic autoimmune diseases and the presence of risk factors for cardiovascular disease and bleeding. Anticoagulation with vitamin K antagonists (VKA) remains the cornerstone of therapy for thrombotic APS. ⋯ Treatment with direct oral anticoagulants (DOACs) could be considered in certain low-risk situations, although they are not recommended in patients with arterial thrombosis or triple positive aPL. Adjuvant therapies such as hydroxychloroquine and statins may be useful in complex settings such as thrombotic recurrences or high risk of bleeding. In this article, we review the evidence and the recommendations of the guidelines for the treatment of APS, and provide a critical and practical approach of its management from our clinical perspective.

Antiphospholipid antibodies (aPL) are a family of autoantibodies targeting phospholipid-binding proteins and are associated with several clinical settings, and most notably define the antiphospholipid syndrome (APS). These antibodies can be identified using a variety of laboratory tests, which include both solid-phase immunological assays and functional clotting assays that detect lupus anticoagulants (LA). aPLs are linked to a range of adverse medical conditions, such as thrombosis and complications affecting the placenta and fetus, potentially leading to morbidity and mortality. ⋯ Therefore, laboratory testing for aPL is crucial for evaluating the risk of complications and for fulfilling certain classification criteria for APS, which are also applied as diagnostic markers in medical practice. This review provides an overview of the available laboratory tests currently for measuring aPL and discusses their clinical implications.

Review Historical Article
Hughes syndrome: The discovery of the antiphospholipid syndrome.
In the 40 years since the original detailed description of antiphospholipid syndrome (APS), the condition has come to be regarded as one of the most common autoimmune diseases. The impact of the description has been enormous - for example, the recognition that some individuals with connective tissue diseases require anticoagulation rather than corticosteroids or anti-inflammatory treatment has bought about fundamental change in medical practice. ⋯ In neurology, APS may be associated with up to 20% of strokes in people under 40 - a striking figure not least in terms of medical economics, let alone in potentially preventable suffering. In vascular medicine, APS links immunology with thrombosis and vascular disease and may well provide insights into immunological factors in the pathogenesis of atherosclerosis.

Bronchiectasis is a clinical-radiological condition composed of irreversible bronchial dilation due to inflammation and infection of the airways, which causes respiratory symptoms, usually productive cough and infectious exacerbations. Bronchiectasis can have multiple causes, both pulmonary and extrapulmonary, and its clinical presentation is very heterogenous. ⋯ Chronic bacterial bronchial infection is common, and Pseudomonas aeruginosa is the pathogen that has been found to imply a worse prognosis. Treatment of bronchiectasis has three fundamental characteristics: it must be multidisciplinary (involvement of several specialties), pyramidal (from primary care to the most specialized units) and multidimensional (management of all aspects that make up the disease).
