Thrombotic events in systemic lupus erythematosus. Its association with acquired and inherited thrombophilic defects.
Systemic lupus erythematosus (SLE) is characterised by increased venous and arterial thrombotic risk. Although antiphospholipid antibodies (APAs) have been shown to be related with thrombotic tendency in these patients, in more than 40% of them, thrombosis occurs without the presence of such antibodies. We analysed the association of venous and arterial thrombotic events with acquired (anticardiolipin antibodies (ACAs) and lupus anticoagulant (LA)) and inherited (antithrombin (AT), protein C (PC), protein S (PS) deficiencies, factor V Leiden and the prothrombin G20210A mutation), thrombophilic risk factors in 86 SLE patients and 89 healthy controls. Patients showed a higher significant perc…
Hemorheological profile in primary and secondary Raynaud's phenomenon. Influence of microangiopathy.
Raynaud's phenomenon (RP) is an episodic peripheral circulatory disorder characterized by local artery spams in subjects exposed to cold or emotional stress. It is not well-established whether RP patients show an altered rheological profile, mostly due to patient classification and clinical severity. We aimed to compare the hemorheological profile in patients with primary and secondary RP with a healthy control group. Eighteen primary RP, 22 secondary RP and 22 healthy controls, were included in the study. RP patients were also divided according to the presence of digital ulcers (7 with, 33 without). Biochemical and hemorheological variables were analyzed, including glucose, triglycerides, …
RDW in patients with systemic lupus erythematosus. Influence of anaemia and inflammatory markers
Red blood cell distribution width (RDW) is a routine parameter that reflects size variations in erythrocytes. High RDW has been associated with cardiovascular events and inflammatory diseases. However, no studies evaluating the association of RDW with systemic lupus erythematosus (SLE) have been published. We aimed to explore the association of RDW with inflammatory markers in SLE. As SLE is often associated with anaemia, we considered this factor in order to know whether RDW is related with inflammation, anaemia or both in SLE. The study included 105 SLE patients (7 men, 98 women; aged 15-73 years) and 105 controls (9 men, 96 women; aged 18-71 years). Patients were divided according to ana…
Homocysteine levels in patients with primary and secondary Raynaud's phenomenon. Its association with microangiopathy severity
The association between hyperhomocysteinemia (HHcy) and Raynaud's phenomenon (RP) remains a matter of debate. In 18 primary RP, 23 secondary RP and 41 controls, we investigated homocysteine (Hcy) levels along with biochemical and inflammatory parameters. The Hcy levels in both primary and secondary RP were elevated when compared with controls (p0.05 and p0.01, respectively). As age was higher in secondary RP as compared with controls (p0.01), both primary and secondary RP were age-matched with a corresponding control group, and with Hcy maintaining its statistical significance (p0.05). No differences in creatinine, B12 vitamin or folic acid were observed between groups (p0.05), or in the pr…
