Exploring the plasmatic platelet-activating factor acetylhydrolase activity in patients with anti-phospholipid antibodies

ConclusionsPAF-AH plasmatic activity is particularly up-regulated in LAC+ and in a β2GPI IgG+ patients, possibly representing an alternative prognostic biomarker for the therapeutic management of APS patients.

Conclusions: 1. Clinical suspicion of APS requires careful diagnostic testing. Because of inadequate diagnostic workup, many patients may not even have an APS, and these patients could be adequately treated with a DOAC. 2. Patients with single or double positive antiphospholipid antibodies but without positive LA may have a comparably low thrombotic risk and may also be treated with a DOAC in venous TE - sufficient evidence for that conclusion is not yet available but is suggested by the results of meta-analyses. 3. Triple positive patients or those with APS who suffered from arterial thromboembolism have a very high ...

Abstract Prognosis of pregnancies in women with antiphospholipid syndrome has dramatically improved over the past two decades using conventional treatment with low molecular weight heparin and low-dose aspirin. However, despite this regimen, 10-15% of antiphospholipid syndrome patients experience pregnancy losses. Several studies have been performed in order to identify risk factors predictive of complications. Thrombosis has been generally accepted as the key pathogenetic mechanism underlying pregnancy morbidity. However, the thrombogenic state alone is not able to explain all the different mechanisms leading to ...

AbstractA false-positive result of syphilis screening test (FPST) is a characteristic finding in patients with systemic lupus erythematosus (SLE). We evaluated the clinical characteristics of SLE patients with FPST at SLE diagnosis. We reviewed the medical records of patients with SLE who underwent the Venereal Disease Research Laboratory or Rapid Plasma Reagin tests at SLE diagnosis at Severance Hospital between 2006 and 2016. The baseline characteristics and clinical outcomes were compared between patients with FPST and those with a negative result of syphilis screening test. Of 145 patients with SLE, 20 patients showed ...

CONCLUSIONS: In prozone effect patients, aPS/PT antibodies are associated with LAC prozone effect as well as thrombosis and decreased factor II levels. PMID: 31598704 [PubMed - as supplied by publisher]

Publication date: Available online 8 October 2019Source: Best Practice &Research Clinical Obstetrics &GynaecologyAuthor(s): Lisa R. SammaritanoAbstractAppropriate contraception and preconception counseling are critical for women of reproductive age with systemic autoimmune diseases since clinical diagnosis, rheumatology medications, and disease activity may impact the safety or efficacy of certain contraceptives as well as the risk of adverse pregnancy outcomes. The presence of antiphospholipid antibodies (anticardiolipin, anti-β2 Glycoprotein I and lupus anticoagulant) is the most important determinant of con...

Antiphospholipid syndrome (APS) is as an autoimmune disease characterized by thrombosis and/or specific pregnancy-related morbidity associated with persistent antiphospholipid antibodies, namely, lupus anticoagulant and IgG and IgM antibodies to cardiolipin and beta2 glycoprotein I. Optimal antibody detection plays a central role in diagnosis and classification. This review discusses antiphospholipid antibodies helpful for diagnosing APS. It includes the criteria and noncriteria antiphospholipid antibodies, methods for their detection, and challenges for clinical reporting and interpretation. The significance of using spec...

Conclusion: As a kind of systemic disease, MT is mainly characterized by painful or painless muscle masses and swelling at a single site or at multiple sites. Patients with a history of tuberculosis and immune system disease are susceptible to MT. A diagnosis is mainly made on the basis of the results of pathological biopsy and bacteriological culture. Early diagnosis and timely standardized anti-tuberculosis treatment can improve the prognosis.

Conclusions: Pregnancy and postpartum were the most common predisposing factors for CVST in our cohort. Although the mortality rate is low, the risk of residual neurological deficit remains high. We recommend a prospective study for better characterization and outcome assessment. PMID: 31555420 [PubMed]

Systemic lupus erythematosus (SLE) is an unusual risk factor for cerebral venous sinus thrombosis (CVST). As few CVST patients with SLE have been reported, little is known regarding its frequency as an underlying etiology, clinical characteristics, or long-term outcome. We evaluated a large cohort of CVST patients with SLE in a multicenter study of cerebral venous thrombosis, the VENOST study, and their clinical characteristics.

We present a case demonstrating histopathological clot findings after endovascular thrombectomy for acute ischaemic stroke in a 38 year-old male with systemic lupus erythematosus and antiphospholipid syndrome (APS). The differential diagnosis was embolism of a suspected Libman-Sacks vegetation or less likely an in-situ thrombosis. Clot analysis provided guidance with patient management and anticoagulation was commenced. The utility of clot analysis in this case provides support for routine clot analysis, which has been standard practice at our institution, and is likely to evolve as endovascular thrombectomy becomes more widely accessible.
