Publication date: Available online 17 July 2018Source: Autoimmunity ReviewsAuthor(s): Aram Musaelyan, Sergey Lapin, Vladimir Nazarov, Olga Tkachenko, Boris Gilburd, Alexandra Mazing, Lilia Mikhailova, Yehuda ShoenfeldAbstractVimentin is a protein of intermediate filament family, which is expressed in all mesenchymal cells. Vimentin plays a key role in the physiology of the cell, cellular interactions and the functioning of the immune system. Post-translationally modified and native forms of vimentin are involved in the pathogenesis of inflammation and many autoimmune diseases: rheumatoid arthritis, sarcoidosis, systemic lu...

Circulating antiphospholipid antibodies (APL) induce vascular injury and endothelial dysfunction, which are associated with thrombotic events and/or fetal loss. We developed a model in which calibrated automated thrombin generation (CAT) is carried out in wells lined with cultured endothelial cells. Then we investigated how far b2GP1 antibodies provoked thrombin generation (TG) enhancing effects in these cells and/or in blood platelets.

ini P Abstract OBJECTIVE: Antibodies that recognize the phosphatidylserine/prothrombin complex (antiphosphatidylserine/ prothrombin antibodies; aPS/PT) might reveal enhanced thrombotic risk in patients with systemic lupus erythematosus. Little is known about their association with pregnancy complications in the antiphospholipid syndrome (APS). METHODS: We enrolled 55 patients with APS who were seeking pregnancy in 2 Italian hospitals. Antiphospholipid antibodies (aPL), including anticardiolipin antibodies, anti-β2-glycoprotein I antibodies, lupus-like anticoagulant, and aPS/PT antibodies were assessed, a...

CONCLUSION: Few existing studies address monitoring for optimal care during SLE pregnancies. The available data imply roles for aPL antibodies measurement (prior to pregnancy and/or during the first trimester), uterine and umbilical artery Doppler studies in the second trimester, and following disease activity. Optimal frequency of monitoring is not addressed in the existing literature. PMID: 30008450 [PubMed - as supplied by publisher]

CONCLUSIONS: There is insufficient evidence to demonstrate benefit or harm of using anticoagulants with or without ASA versus ASA alone in people with aPL antibodies and a history of recurrent pregnancy loss and with no such history; ASA versus placebo in people with aPL antibodies; and ASA with LMWH versus placebo or IVIG, and ASA with high-dose LMWH versus ASA with low-dose LMWH or UFH, in women with aPL antibodies and a history of recurrent pregnancy loss, for the primary prevention of thrombotic events. In a mixed population of people with a history of previous pregnancy loss and without such a history treated with ant...

ConclusionBecause 28% of our patients with longstanding and strictly defined PAPS could be mistakenly classified as SLE, they were at risk of deleterious therapeutic management. We therefore suggest that any future classification for SLE should specifically require at least one SLE-specific criterion for patients with aPL.

ConclusionsAnti-DI antibody positivity can be considered a new risk factor predictive of the first thrombotic event in aPL carriers, instead, negative anti-DI may be useful to identify low-risk aPL carriers.

ConclusionsWith inclusion of LAC, the ELISA and CIA show comparable performance for the diagnosis of APS. However, correlations of APS-specific manifestations were dependent on method of detecting the aPL antibodies suggesting platforms may not be used interchangeable.
