Objectives: To compare the serum concentrations of the selected cytokines from subsequent trimesters of antiphospholipid syndrome complicated pregnancies.
Material And Methods: This study included 43 pregnant women (23 patients diagnosed with antiphospholipid syndrome and 20 controls). IL-2R, IL-4, IL-10, INF-gamma, TNF-alpha, and class I sHLA concentrations were analyzed by ELISA in the 1st, 2nd and 3rd trimester
Results: INF-gamma levels were below the method detection threshold and therefore were not included in the final analysis. No significant changes in IL-2R, IL-4, IL-10, TNF-alpha, and class I sHLA concentrations were observed in subsequent trimesters in the group of women with antiphospholipid syndrome. Significant decrease in IL-10 in the 2nd trimester along with significant increase in TNF-alpha in the 3rd trimester were noted amongst the control subjects. The only significant inter-group difference was observed in the 1st trimester when mean TNF-alpha level was significantly higher among antiphospholipid syndrome women if compared to controls.
Conclusions: The observed lack of significant differences between antiphospholipid syndrome affected and control group pregnancies in their sHLA class I and cytokine concentrations may be related to the fact that the treatment of antiphospholipid syndrome was implemented early and continued throughout all trimesters of the pregnancy.

Several neurological conditions, including transient global amnesia (TGA), may present an isolated sudden-onset temporary amnestic symptom. TGA is a benign, self-remitting neurological condition associated with hippocampal dysfunction. Meanwhile, certain other neurological conditions, such as cerebral ischemic stroke and hippocampal epilepsy, require appropriate therapeutic interventions.

Antibodies to β2-glycoprotein I (β2GPI) cause thrombosis in antiphospholipid syndrome, however the role of β2GPI in coagulation in vivo is not understood. To address this issue, we developed β2GPI-deficient mice (Apoh-/-) by deleting exon 2 and 3 of Apoh using CRISPR/Cas9 and compared the development of thrombosis in wild-type (WT) and Apoh-/- mice using rose bengal and FeCl3-induced carotid thrombosis, laser-induced cremaster arteriolar injury, and inferior vena cava (IVC) stasis models. We also compared tail bleeding times and activation of platelets from WT and Apoh-/- mice in the absence and presence of β2GPI.

To identify clusters of autoantibodies in a large cSLE population and to verify possible associations between different autoantibody clusters and the following variables: demographic data, cumulative clinical and laboratory manifestations, disease activity, cumulative damage and mortality. A cross-sectional study was performed in 27 Pediatric Rheumatology University centers, including 912 cSLE patients. The frequencies of seven selected autoantibodies (anti-dsDNA, anti-Ro/SSA, anti-La/SSB, anti-Sm, anti-RNP, aCL IgM and/or IgG and LA) were used for cluster analysis using the K-means method.

Cancer and antiphospholipid syndrome (APS) independently increase thrombotic risk, and their coexistence can create a particularly hazardous prothrombotic state. This case report aims to highlight the complex challenges in managing concurrent thrombotic and hemorrhagic events in patients with a history of cancer and APS. The combination of these conditions presents a rare and difficult clinical scenario, requiring careful consideration in anticoagulation management.

Little is known about how patients with antiphospholipid syndrome (APS) or antiphospholipid antibodies (aPL) access and trust health information. This research aimed to: describe the sources of information most frequently accessed/trusted by patients with APS/aPL; identify if individuals with APS/aPL perceived their health had been negatively impacted by various sources and document obstacles to accessing health information. Patients meeting Revised Sapporo Criteria for APS or with ≥1 positive aPL on ≥2 occasions were recruited to an online survey regarding their health information use at diagnosis and within 6 months preceding survey completion.
