Periodontal Disease in Rare Renal Disorders (PERIO-RA-RE)

This study aims to evaluate the burden and phenotypic spectrum of periodontal disease in patients with rare kidney disorders (such as Alport syndrome, Fabry disease, and tuberous sclerosis complex) and systemic lupus erythematosus (SLE), compared with chronic kidney disease (CKD) controls and population controls. This is a cross-sectional, case-control observational study. Participants will undergo a single structured evaluation including a full-mouth periodontal examination, a clinical questionnaire, and collection of relevant clinical and nephrological data. The primary objective is to compare the prevalence of periodontitis across study groups. Secondary objectives include characterization of periodontal disease severity, prevalence of gingivitis and xerostomia, and identification of disease-specific oral phenotypes. Exploratory analyses will assess associations between periodontal disease and clinical variables such as kidney function, proteinuria, and immunosuppressive exposure.

Evaluation of Plasma Vitamin C Levels in a Population of Chronic Rheumatism in Immuno-Rheumatology

Scurvy is an almost forgotten carential pathology, caused by a deep vitamin C (or ascorbic acid) deficiency, a priori exceptional in industrialized countries. According to the French National Authority for Health standards, hypovitaminosis C is defined as a plasma vitamin C level of less than 23 μmol/L. This deficiency would affect 5 to 10% of the general population in industrialized countries and from 17% (clinical scurvy) to 47% (biological hypovitaminosis C) of vulnerable populations (malnutrition, hospitalized patients...). Vitamin C is essential for collagen synthesis. It plays a cofactor role in the synthesis of catecholamines precursors and takes action in synthesis of certain amino acids. In rheumatology, pain is a recurring reason for consultation. In a context of treated chronic inflammatory rheumatism (RIC), while most of patients seem in remission or in reduced activity of their disease, all real-life studies show that 30 to 40% of them complain of residual pain, 70% of chronic fatigue and 20-25% of symptoms similar to secondary fibromyalgia. Currently, authors suggest the interest of vitamin C analgesic properties, especially in musculoskeletal pain, due to the role of ascorbic acid in neurotransmitters. Vitamin C would act as a cofactor for a family of biosynthetic and regulatory metalloenzymes. Thus, the authors suggest the potential of vitamin C in an analgesic mechanism involving the biosynthesis of opioid peptides.

Teams Engaged in Accessible Mental Health Interventions for Lupus Erythematosus and Dermatomyositis Stress

The objectives of this study are to determine if the 'Teams Engaged in Accessible Mental Health Interventions for Lupus Erythematosus and Dermatomyositis Stress' (TEAM-LEADS) intervention is feasible and acceptable to adolescents and young adults with lupus and dermatomyositis and whether it can help reduce stress and promote cardiovascular health behaviors in these individuals.

Effects of Telitacicept vs Cyclophosphamide on Lupus Related Interstitial Lung Disease

Recent data indicate that Telitacicept is beneficial for lupus nephritis. Our goal is to determine whether Telitacicept is an effective and safe treatment, compared to standard-of-care Cyclophosphamide, for subclinical and clinical ILD in patients with early lupus.
