Project description:Purpose of reviewCatastrophic antiphospholipid syndrome (CAPS) is a severe manifestation of antiphospholipid syndrome (APS). Although affecting only 1% of patients with APS, the condition is frequently fatal if not recognized and treated early. Here, we will review the current approach to diagnosis and treatment of CAPS.Recent findingsData from the international 'CAPS registry', spearheaded by the European Forum on Antiphospholipid Antibodies, have improved our understanding of at-risk patients, typical clinical features, and precipitating diagnoses. Current guidelines also continue to support the role of anticoagulants and glucocorticoids as foundation therapy in all patients. Finally, new basic science and case series suggest that novel therapies, such as rituximab and eculizumab, warrant further study.SummaryAttention to associated diagnoses, such as infection and systemic lupus erythematosus (SLE), is critical at the time of diagnosis. All patients should be treated with anticoagulants, corticosteroids, and possibly plasma exchange. In patients with SLE, cyclophosphamide should be considered. In refractory or relapsing cases, new therapies, such as rituximab and possibly eculizumab, may be options, but need further study.

Project description:Catastrophic antiphospholipid syndrome (CAPS) is a rare and life-threatening condition characterized by the persistence of antiphospholipid antibodies and occurrence of multiple vascular occlusive events. CAPS currently remains a diagnostic challenge and requires urgent treatment. The diagnosis of CAPS is made difficult by classification criteria used as diagnostic criteria in clinical practice, knowledge derived from retrospective data and case reports, confounding clinical and biological features, and its rapid onset and mortality. The absence of prospective studies of CAPS limits the strength of evidence for guideline treatment protocols. This comprehensive review summarizes the current understanding of the disease, and discusses how the 2023 ACR/EULAR Antiphospholipid Syndrome Classification Criteria impact the definition and therapeutic management of CAPS, which is considered the most severe form of APS. The correct integration of 2023 ACR/EULAR APS classification criteria is poised to facilitate CAPS diagnosis, particularly in critical situations, offering a promising avenue for improved outcomes.

Project description:BackgroundAntiphospholipid syndrome (APS) is an autoimmune response characterized clinically by arterial or venous thrombosis. One of the rare and series forms of APS is the catastrophic APS (CAPS). The incidence of CAPS has been reported in 0.8% of patients with APS. There have been very few case reports with cardiac involvement in CAPS. Common cardiac manifestations include valvular thickening and lesions, coronary artery disease, and myocardial infarction due to microvascular thrombosis. Here, we are reporting a case of CAPS associated with heart failure and a literature review of similar cases.Case summaryA 24-year-old woman with a history of APS presented with shortness of breath and right-sided pleuritic chest pain. Computed tomography pulmonary angiogram revealed new pulmonary emboli in the right lung. After 5 days, she developed high-grade fever with negative infectious workup, acute hypoxic respiratory failure with pulmonary oedema, shock, acute kidney injury, and transthoracic echocardiography showed reduced ejection fraction and global hypokinesia. The constellation of multi-organ failure, symptoms within a week, the presence of antiphospholipid antibodies, and exclusion of other causes, CAPS was diagnosed. The patient showed significant improvement with pulse steroids, IV plasmapheresis and got discharged on oral prednisone taper and anticoagulation with home health.ConclusionThere are different cardiac complications associated with CAPS, including congestive heart failure, acute coronary syndrome, valvular lesions, and thrombus. Heart failure management in CAPS includes triple therapy of intravenous immune globulin, IV plasmapheresis, and corticosteroids rather than conventional treatment.

Project description:ImportanceCatastrophic antiphospholipid syndrome (CAPS) is a severe, rare complication of antiphospholipid syndrome (APS), but cutaneous involvement has not yet been adequately described.ObjectiveTo describe cutaneous involvement during CAPS, its clinical and pathological features, and outcomes.Design, setting, and participantsThis cohort study was a retrospective analysis of patients included in the French multicenter APS/systemic lupus erythematosus register (ClinicalTrials.gov: NCT02782039) by December 2020. All patients meeting the revised international classification criteria for CAPS were included, and patients with cutaneous manifestations were analyzed more specifically.Main outcomes and measuresClinical and pathological data as well as course and outcome in patients with cutaneous involvement during CAPS were collected and compared with those in the register without cutaneous involvement.ResultsAmong 120 patients with at least 1 CAPS episode, the 65 (54%) with skin involvement (43 [66%] women; median [range] age, 31 [12-69] years) were analyzed. Catastrophic antiphospholipid syndrome was the first APS manifestation for 21 of 60 (35%) patients with available data. The main lesions were recent-onset or newly worsened livedo racemosa (n = 29, 45%), necrotic and/or ulcerated lesions (n = 27, 42%), subungual splinter hemorrhages (n = 19, 29%), apparent distal inflammatory edema (reddened and warm hands, feet, or face) (n = 15, 23%), and/or vascular purpura (n = 9, 14%). Sixteen biopsies performed during CAPS episodes were reviewed and showed microthrombi of dermal capillaries in 15 patients (94%). These lesions healed without sequelae in slightly more than 90% (58 of 64) of patients. Patients with cutaneous involvement showed a trend toward more frequent histologically proven CAPS (37% vs 24%, P = .16) than those without such involvement, while mortality did not differ significantly between the groups (respectively, 5% vs 9%, P = .47).Conclusions and relevanceIn this cohort study, half the patients with CAPS showed cutaneous involvement, with a wide spectrum of clinical presentations, including distal inflammatory edema. Skin biopsies confirmed the diagnosis in all but 1 biopsied patient.

Project description:Catastrophic antiphospholipid syndrome is a rare multisystem autoimmune condition characterised by rapid development of widespread thrombotic disease and subsequent multi-organ failure. It is the most severe complication of antiphospholipid syndrome, carrying significant morbidity and mortality. We report a patient with post-partum catastrophic antiphospholipid syndrome with cardiac, hepatic, renal and cutaneous manifestations. The diagnostic challenges in establishing a definitive diagnosis in catastrophic antiphospholipid syndrome is discussed, along with the difficulties in managing these patients in the intensive care unit.

Project description:Catastrophic antiphospholipid syndrome is a rare disorder that remains under-recognized causing a high mortality rate even with treatment. Factors such as infections and systemic lupus erythematosus flare play as an inciting event in the thrombotic crisis which underlies catastrophic antiphospholipid syndrome. The use of plasmapheresis has improved the outcome of such cases with a reduction in mortality rate from over 50% to less than 30%, according to some studies. However, the definitive treatment of this disabling and fatal condition remains an area warranting research. Case 1. A case of 32-year-old female with a background of epilepsy and recurrent abortions who presented with difficulty in breathing, dry cough, and bilateral lower limb swelling. The patient initially received treatment with cyclophosphamide and systemic corticosteroids after being diagnosed with systemic lupus erythematosus. She also underwent plasmapheresis for suspected pulmonary hemorrhage as her condition deteriorated rapidly requiring intensive care. The diagnosis was revised as catastrophic antiphospholipid syndrome given the typical multi-organ involvement, namely, cerebritis, Libman-Sacks endocarditis, and nephritis apart from the pulmonary involvement. Eventually, hydroxychloroquine was added to the regimen which led to a remarkable improvement in her condition after a few days. Case 2. A case of 28-year-old female with history of recurrent abortions presented with abdominal pain and was admitted as a case of pancreatitis. The patient received intravenous fluids and analgesics with no significant improvement. Later, she developed multi-organ failure requiring critical care. Given her history and clinical presentation along with the multi-organ involvement in an acute setting, she underwent extensive workup that favored catastrophic antiphospholipid syndrome and she was started on Aspirin initially, and then, hydroxychloroquine was administered. Few days after initiation, her condition improved markedly and with complete resolution of her abdominal symptoms. Hydroxychloroquine's antithrombotic effect in synergy with other therapies has been observed in our cases. Yet, its role in the early course of catastrophic antiphospholipid syndrome merits further investigation.
