INTRODUCTION Defects in the regulation of apoptosis of autoreactive lymphocytes are involved in the pathogenesis of systemic lupus erythematosus (SLE). The apoptotic process relies on adequate functioning of numerous molecules, including oncogenes and diverse cytokines. p53 has been implicated in the control of the cell cycle through the stimulation of(More)
The antiphospholipid syndrome (APS) is characterized by the presence of venous and arterial thrombosis, recurrent fetal losses and thrombocytopenia, associated with the presence of antiphospholipid antibodies (aPL). This syndrome may be "primary" or may be associated with other diseases, mainly systemic lupus erythematosus (SLE). However, some patients(More)
BACKGROUND Different oncogenes (Fas and bcl-2) and diverse cytokines (IL-10 and alfa-TNF) may have an effect on the regulation of apoptosis. The majority of studies to date have evaluated only one or two of these elements independently and it is difficult to obtain a global view of apoptosis disregulation in the pathogenesis of systemic lupus erythematosus(More)
OBJECTIVE Bcl-2 translocation or overexpression is found in many types of malignancy, possibly through alteration of the apoptosis mechanism. It has also been suggested that similar apoptotic alterations may be important in the pathogenesis of systemic lupus erythematosus (SLE). It is believed that a process of apoptosis at the stage of maturation or(More)
OBJECTIVE To determine the prevalence and correlation with clinical manifestations of the IgG and IgM isotypes of antibodies to cardiolipin (aCL), phosphatidic acid (aPA), phosphatidylinositol (aPI) and phosphatidylserine (aPS) in patients with systemic lupus erythematosus (SLE). METHODS Clinical and laboratory features of 92 consecutive unselected(More)
OBJECTIVES To determine the prevalence and clinical significance of hepatitis C virus (HCV) infection in a large cohort of patients with "primary' Sjögren's syndrome (SS). METHODS 90 consecutive patients (83 female and seven male) were included, with a mean age of 62 years (range 31-80) who prospectively visited our unit. All patients fulfilled the(More)
OBJECTIVE To determine the prevalence and clinical significance of antiphospholipid antibodies (aPL) in a cohort of patients with primary Sjögren's syndrome (SS). METHODS Eighty patients with primary SS were studied prospectively. The prevalence of aPL and characteristics of the clinical and laboratory features of these patients were compared with those(More)
The pathogenesis and therapy of shrinking lungs syndrome in patients with systemic lupus erythematosus remains controversial. It has been previously reported that corticosteroid treatment can be effective. We report a patient with shrinking lungs syndrome who presented a good response to inhaled beta-agonist therapy. Therapeutic approach to this syndrome is(More)
We determined the prevalence and relationship with clinical manifestations of antibodies to thromboplastin (aTP) in 92 patients with systemic lupus erythematosus (SLE). Thirty-two (35%) patients had aTP: 13 (14%) were positive for IgG aTP, 13 (14%) for IgM aTP, and 6 (7%) for both. Patients with aTP had an increased incidence of thrombosis (p = 0.01),(More)
