There is ongoing debate as to whether abacavir (ABC) increases the risk for cardiovascular disease(CVD) in people living with HIV (PLHIV) and the mechanisms underlying this possible association. We re...
Disorders of haemostasis result in both excessive bleeding and clotting and are a major global cause of morbidity and mortality, particularly in the developing world. A small number of simple tests ca...
To determine the significance of antibodies to the phosphatidylserine/prothrombin complex (aPS/PT) in patients with systemic lupus erythematosus (SLE) antiphospholipid syndrome (APS)....
A total of 190 patients were included in the study: 123 (64.7%) with reliable SLE and 55 (29%) with PAPS. The control group included 100 relatively healthy subjects of comparable age. All patients wer...
Based on the average values of IgG/IgM aPS/PT of the control group, the levels of positivity were allocated mean (M) + 3 or 5 standard deviations (SD): M+3SD and M+5SD. IgG aPS/PT levels above 73.6 U/...
The frequency of detection of IgG aPS/PT in the examined patients was 44%, IgM aPS/PT 29% and their combination 19% of 190 patients. Half of the patients with probable APS had positive IgG aPS/PT and ...
Anti-phosphatidylserine prothrombin antibodies (aPSPT) are reported to be highly associated with the lupus anticoagulant (LAC) in established antiphospholipid syndrome (APS) and systemic lupus erythem...
To determine the sensitivity and specificity of aPSPT to the LAC in an all-comer population undergoing evaluation for suspected APS....
An assembled cross-sectional cohort from June 2017 to December 2018 undergoing APS evaluations across all medical specialties were reviewed for LAC, aPSPT, anti-cardiolipin (aCL), and anti-β2 glycopro...
A cohort of 166 eligible patients was identified. Seventy-one percent were female, 89% White, 15% with SLE, and 21% with APS. The aPSPT was found to be the most specific to the LAC. Specificity of IgG...
Anti-phosphatidylserine/prothrombin (aPS/PT) antibodies are the major contributor to activated Protein C resistance (APC-R) in tetra-positive thrombotic high-risk patients with Antiphospholipid Syndro...
To evaluate the role of phospholipids (PL) on aPS/PT mediated APC-R....
Total IgG were purified from plasma of 6 tetra-positive patients and IgG aPS/PT were affinity-purified from 3 of these patients. Purified material was spiked into Normal Pooled Plasma (NPP) and tested...
Total IgG showed APC-R at low PL concentration (1.5 μg/mL) that disappeared at increasing PL concentrations (5.8, 11.6 and 46.6 μg/mL). In the same way, affinity purified aPS/PT showed a robust (59 %,...
Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by the presence of antiphospholipid antibodies (aPLs), which can lead to thrombosis and pregnancy complications. Within the dive...
Current assays that monitor thrombin generation in plasma rely on fluorogenic substrates to follow the kinetics of zymogen activation, which may be complicated by substrate cleavage from other proteas...
To develop a plasma assay that directly monitors prothrombin activation independent of fluorogenic substrate hydrolysis....
Cleavage at the R271 site of prothrombin is monitored through loss of Förster resonance energy transfer in plasma coagulated along the extrinsic or intrinsic pathway....
The availability of factor (F)V in plasma strongly influences the rate of prothrombin activation. The rate of thrombin formation is equally perturbed in FV or prothrombin-depleted plasma, implicating ...
The Förster resonance energy transfer assay enables direct monitoring of prothrombin activation through cleavage at R271 without the need for fluorogenic substrates. The assay is sensitive enough to a...
Assessment of the prevalence of anti-phosphatidylserine-prothrombin antibodies (aPS/PT) with OAPS and SN-OAPS in Chinese patients....
This retrospective study proceeded at Ren Ji Hospital, Shanghai, China, from January 2019 to January 2020. Two hundred eleven OAPS, 68 SN-OAPS, 81 disease controls, and 30 healthy donors were enrolled...
Thirty-three OAPS (15.64%) and 31 SN-OAPS (45.59%) were positive for aPS/PT. aPS/PT IgM showed a high Youden index (.813), which classified OAPS and SN-OAPS patients from healthy controls and other au...
aPS/PT antibody showed an efficient diagnostic value for Chinese patients with OAPS and SN-OAPS, which could be a potential risk predictor for obstetric complications....
The role of thrombotic factors in the pathogenesis and progression of liver fibrosis remains obscure. We aimed to study the relationship between prothrombin G20210A (PT20210) and factor V Leiden (FVL)...
The study included 100 subjects, 88 patients with HCV-related cirrhosis (compensated: 38, decompensated: 50), and 12 controls. Patients with other viral hepatitis or coinfection, inherited metabolic d...
FVL and PT20210 mutations were significantly higher in decompensated vs. compensated patients (32% vs. 5.3%, P = 0.001; 20% vs. 5.3%, 0.043, respectively) and absent in controls. Both mutations signif...
Both mutations are significantly correlated to fibrosis progression and liver profile and could be considered as markers predicting the need for early and different intervention....
Antithrombin resistance (ATR) is a newly identified strong genetic predisposition to venous thromboembolism (VTE) caused by genetic variations in prothrombin with substitutions of Arg at position 596 ...
