Collating the voice of people with autoimmune diseases: Methodology for the Third Phase of the COVAD Studies.

INTRODUCTION: The growing recognition of holistic patient care highlights the various factors shaping the quality of life of individuals with autoimmune and rheumatic diseases (AIRDs). Beyond the traditional disease measures, there is an emerging acknowledgment of the less-explored aspects, including subjective well-being, social determinants of health, comorbidities, mental health, and medication adherence. Moreover, digital health services have empowered patients to engage actively in decision-making alongside clinicians. To explore these domains within the context of AIRDs, the "Collating the Voice of People with Autoimmune Diseases" COVAD survey was conceived, a successor of the previous two COVAD surveys. In this document, we present the study protocol in comprehensive detail. METHODS: The COVAD-3 survey is a cross-sectional patient self-reported e-survey incorporating multiple widely accepted scales/scores to assess various aspects of patients' lifestyles objectively. To ensure the survey's accuracy and usability across diverse regions, it will be translated into multiple languages and subjected to rigorous vetting and pilot testing. It will be distributed by collaborators via online platforms and data will be collected from patients with AIRDs, and healthy individuals over eight months. Data analysis will focus on outcome measures related to various social, demographic, economic, and psychological factors. CONCLUSION: With the increasing awareness to adopt a holistic treatment approach encompassing all avenues of life, the COVAD-3 survey aims to gain valuable insights into the impact of social, demographic, economic, and psychological determinants of health on the subjective well-being in patients with AIRDs, which will contribute to a better understanding of their overall health and well-being.

Musculoskeletal disorders in hemodialysis patients: different disease clustering according to age and dialysis vintage.

Musculoskeletal disorders remain a major problem in hemodialysis patients. The aim of the study was to estimate the prevalence of musculoskeletal manifestations in hemodialysis patients and identify disease cluster profiles. We performed a cross-sectional study including all adult patients in the hemodialysis unit at Hotel-Dieu de France Hospital. We collected demographic characteristics, musculoskeletal symptoms, biologic parameters, and treatments. Musculoskeletal disorders were classified by a rheumatologist into predefined diagnostic categories. Prevalence was presented, and a cluster analysis was performed. Eighty-nine patients were included, mean age was 67.5 ± 12 years, and 43.8% were female. Dialysis vintage was 5.7 ± 5.37 years. Musculoskeletal symptoms were reported by 76.4% of the patients. Pain was the most frequent symptom (44.9%). The main diagnoses were osteoarthritis (53.9%) and fracture (27%). Musculoskeletal symptoms and disorders were significantly associated with dialysis vintage and age. Cluster analysis identified three patient profiles: younger with low calcium levels, younger but long dialysis vintage with osteoarthritis and carpal tunnel syndrome, and older with long dialysis vintage and fractures. The prevalence of musculoskeletal manifestations is high in the hemodialysis population and increases with dialysis vintage. Musculoskeletal disorders cluster according to age and dialysis vintage. Key Points• Musculoskeletal symptoms are highly prevalent among hemodialysis patients (76.4%).• All musculoskeletal disorders are associated with dialysis vintage and age.• Three clusters are identified among hemodialysis patients: young with low calcium levels, young but long dialysis vintage with osteoarthritis and carpal tunnel syndrome and old with long dialysis vintage with fractures.

Prevalence and predictors of vitamin D inadequacy amongst Lebanese osteoporotic women.

In Middle-Eastern countries, more particularly in Lebanon, the incidence of vitamin D deficiency has been found to be surprisingly high in schoolchildren and young individuals. However, the prevalence and risk factors for vitamin D inadequacy amongst Lebanese osteoporotic women seeking medical health care has never been studied. We analysed vitamin D-inadequacy risk factors among the 251 Lebanese postmenopausal osteoporotic women (from both Muslim and Christian communities) who participated in a vitamin D international epidemiological study. Vitamin D inadequacy prevalence (25-hydroxyvitamin D (25(OH)D) , 30 ng/ml) was 84.9%. 25(OH)D was negatively correlated with BMI (r 20.41; P<0.001) and positively correlated with educational level (r 0.37; P<0.001) and self-reported general health (r 0.17; P<0.01). No significant correlation was found with age and no seasonal variation was observed. There was no significant correlation between 25(OH)D and sun exposure index or vitamin D-rich food consumption. However, 25(OH)D strongly correlated with vitamin D supplement intake (r 0.48; P<0.0001). Muslim community participants had lower 25(OH)D levels compared with their Christian counterparts (P<0.001). They also had higher BMI, lower educational level and vitamin D supplement consumption and followed more frequently a dress code covering the arms (P<0.0001 for all variables). In a multivariate model, in Muslims, inadequate vitamin D supplements and a dress code covering the arms are the independent predictors of 25(OH)D inadequacy (P<0.001 for both variables). However, in Christians, the predictors are inadequate vitamin D supplements, high BMI and low educational level (P<0.001; P=002 and P=0.02 respectively). There is an urgent need to increase vitamin D supplement use in Middle-Eastern osteoporotic women, more particularly in those from the Muslim community.
