Impact of Baseline Thrombocytopenia on Early Outcomes in Patients With Acute Venous Thromboembolism.

Managing acute venous thromboembolism (VTE) in patients with thrombocytopenia is challenging. We used data from the RIETE registry to investigate the impact of baseline thrombocytopenia on early VTE-related outcomes, depending on the initial presentation as pulmonary embolism (PE) or isolated lower-limb deep vein thrombosis (DVT). From March 2003 to November 2022, 90 418 patients with VTE were included.

Cutaneous vasculitis in primary Sjögren syndrome: classification and clinical significance of 52 patients.

To analyze the different clinical and histologic types of cutaneous vasculitis in patients with primary Sjögren syndrome (SS), we investigated the clinical and immunologic characteristics of 558 consecutive patients with primary SS from our units and selected those with clinical evidence of cutaneous lesions, excluding drug reactions and xeroderma. All patients fulfilled 4 or more of the diagnostic criteria for SS proposed by the European Community Study Group in 1993. A total of 89 (16%) patients presented with cutaneous involvement (88 female patients and 1 male; mean age, 51.

Relationship of p53 with other oncogenes, cytokines and systemic lupus erythematosus activity.

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 apoptosis of these autoreactive cells.
