Proteins Involved in the Induction of Procoagulant Activity and Autoimmune Response in Patients With Primary Antiphospholipid Syndrome.

The aim of this study was to determine the plasma protein profile of patients with primary antiphospholipid syndrome (PAPS) compared to healthy controls and identify proteins that might be used in the evaluation, diagnosis, and prognosis of this condition. The sample consisted of 14 patients with PAPS and 17 sex- and age-matched controls. Plasma samples were submitted to proteomic analysis (albumin and immunoglobulin G depletion, concentration, digestion, and label-free data-independent mass spectrometry).

Evaluation of disease activity in a low-income juvenile idiopathic arthritis cohort.

Determine disease activity in a low income juvenile idiopathic arthritis (JIA) cohort. 164 JIA patients from families with less than US$ 4500.00/capita mean annual income followed in Fortaleza-CE, Brazil, were cross-sectionally evaluated between May 2015-April 2016.

Vitamin D levels in juvenile idiopathic arthritis from an equatorial region.

We aimed to describe the serum levels of 25-hydroxyvitamin D (25OHD) in juvenile idiopathic arthritis (JIA) patients living in a low-latitude (3°43'S) region. Fifty JIA patients, 31 (62 %) female, seen between May 2012 and April 2013 in the northeast of Brazil had clinical data and serum collected for determination of 25OHD and parathyroid hormone (PTH) using a chemiluminescent ELISA; 20 age- and sex-matched controls were used for comparison. Mean age was 13.

Penile alterations with severe sperm abnormalities in antiphospholipid syndrome associated with systemic lupus erythematosus.

This study aims to perform global gonadal and sexual function assessments in systemic lupus erythematosus-related antiphospholipid syndrome (SLE-APS) patients. A cross-sectional study was conducted in ten SLE-APS male patients and 20 healthy controls. They were assessed by demographic data, clinical features, urological examination, sexual function, testicular ultrasound, seminal parameters, sperm antibodies, and hormone profile.
