Article Synopsis
- - The study investigates how environmental factors, specifically climate-related natural hazards, may affect the diagnosis and symptoms of Sjögren's syndrome across different countries, examining aspects like epidemiological profiles and sicca symptoms.
- - Researchers analyzed data from 16,042 patients in 23 countries, determining that those in countries severely impacted by climate hazards (like extreme precipitation and flooding) were often diagnosed with Sjögren's syndrome earlier and exhibited varying symptom frequencies.
- - Findings revealed statistically significant patterns, indicating lower occurrences of dry eyes and mouth in patients from countries facing specific climate threats, while showing that increased climate-related risks correlated with higher disease activity scores (ESSDAI).
Objectives: To analyse how the potential exposure to air pollutants can influence the key components at the time of diagnosis of Sjögren's phenotype (epidemiological profile, sicca symptoms, and systemic disease).
Methods: For the present study, the following variables were selected for harmonization and refinement: age, sex, country, fulfilment of 2002/2016 criteria items, dry eyes, dry mouth, and overall ESSDAI score. Air pollution indexes per country were defined according to the OECD (1990-2021), including emission data of nitrogen and sulphur oxides (NO/SO), particulate matter (PM2.
The correct balance between reactive oxygen species and antioxidant defense in an organism is disturbed in oxidative stress. To assess oxidative balance in 36 SSc patients and 26 healthy controls (HCs), we measured reactive oxidative metabolites (ROMs), total antioxidant capacity (TAC), lipid peroxidation (measuring 4-HNE), and DNA oxidative damage (measuring 8-OHdG) in serum. Furthermore, DNA breaks in leukocytes of 35 SSc patients and 32 HCs were evaluated using COMET.
