NCT06554496
The level of xanthine oxidoreductase (XOR) in plasma is associated with oxidative stress and inflammation. Obstructive Sleep Apnea (OSA) is characterized by repeated upper airway obstruction and apneas during sleep, leading to chronic intermittent hypoxemia. The specific role of XOR in OSA, its relationship with the severity of OSA, and the changes in XOR levels before and after CPAP treatment remain unclear. The study will enroll 80 patients from the First Affiliated Hospital of Nanjing Medical University, categorized by their Apnea-Hypopnea Index (AHI) into mild, moderate, and severe OSA groups. Participants will undergo baseline assessments including polysomnography (PSG) and measurements of XOR activity and biomarkers such as uric acid, endothelin-1 (ET-1), endothelial nitric oxide synthase (eNOS), and inflammatory markers. Eligible patients will receive CPAP treatment for 3 months, after which their XOR activity and biomarker levels will be re-evaluated to assess treatment efficacy.

The objective of this study is to evaluate the performance of the Sansa device for the diagnosis of sleep disordered breathing.
NCT06551389
Systemic lupus erythematosus is a complex systemicautoimmune disease that can affect most organs of the human body. Although they are many recommendations on the diagnosis and managment of SLE, diagnosis and therapeutic managment is still challenging. A pluridisciplinary consultation grouping rheumatologist, nephrologist, dermatologist, gynecologist, internist and immunologists has been set up in 2009 at the university hospital of Brest. The investigators would like to identify in a longitudinal cohort the occurrence of the different clinico-biological and immunological patterns of systemic lupus erythematosus patients during our multidisciplinary consultation. It is now crucial to organize a standardized data collection of these patients in order to evaluate our pratices, to be able to study the epidemiology of SLE in our city, and to promote this initiative at national and international level.
