Venous gangrene (VG) is defined as a clinical triad of skin necrosis and discolouration, documented evidence of venous thromboembolism (VTE) and presence of palpable or doppler-identifiable arterial pulsation. Venous gangrene is rare condition which is associated with poor prognosis in cancer patients. The pathogenesis of VG is multifactorial and could paradoxically be due to warfarin treatment...

The prevalence of antiphospholipid and antinuclear antibodies in 102 patients with at least three unexplained miscarriages before a gestational age of 12 weeks, or at least one intrauterine fetal death after 12 weeks, was investigated and compared with the prevalence in 102 normal pregnant controls. Six patients had a history of thrombosis and six had 'lupus-like' disease. Twenty one patients h...

OBJECTIVE To determine whether high levels of antibodies against the phospholipid beta2-glycoprotein I (beta2-gpI) cofactor are associated with an increase in the risk of acute myocardial infarction. METHODS The study comprised 82 patients with acute myocardial infarction and 82 controls, who were assessed in regard to age, sex, race, hypertension, smoking, previous heart disease, history of ...

Antiphospholipid antibodies (APLA) may be detected in normal pregnancies and also may cause thrombosis, recurrent fetal loss, placental infarction and preeclampsia. In the present study the possible differences in APLA titer between healthy pregnant women and preeclampsia cases without history of thrombosis was examined. The APLA titer in 50 healthy pregnant women with 50 preeclampsia cases wit...

OBJECTIVE To evaluate the frequency of clinical and laboratory manifestations in patients with primary antiphospholipid syndrome (PAPS) with positive antinuclear antibodies (ANA Hep-2+) compared to those in whom this antibody is negative (ANA Hep-2-). PATIENTS AND METHODS This is a transversal study with 58 patients (82.8% females) with PAPS. Demographic and clinical data, comorbidities, medi...

Antiphospholipid antibodies, that is, lupus anticoagulants and anticardiolipin antibodies, are associated with thrombosis and obstetric complications in the antiphospholipid syndrome. Venous thrombosis occurs mostly in the lower limbs, with or without pulmonary embolism, and cerebral ischemia and transient ischemic attacks are the most common arterial events. Overall, the prevalence of thrombos...

Objectives In 20 patients (37%) high level of IgG anticardiolipin antibodies was discovered. High level of anticardiolipin antybodies IgM was discovered in 6 patients (11.1%). Lupus anticoagulant was determinated in 51 cases, in 17 was positive (31%). 8 patients had the tests for anti beta2GPI carried out and in 4 cases it was positive. In the group of 54 patients 22 (41%) presented prolonged a...
