Résumé
Introduction Vitamin D plays a major role in bone metabolismand neuromuscular function. Supplementation with vitamin D iseffective to reduce the risk of fall and of fracture. However adherenceto oral daily vitamin D is low. Screening and correcting vitamin Dinsufficiency in a rheumatologic population could improve bothmorbidity and quality of life. After determining the prevalence ofvitamin D deficiency in this population, we evaluated if supplementationwith a single high dose of oral 25-OH vitamin D3 wassufficient to correct this abnormality.Methods During one month (November 2009), levels of 25-OHvitamin D were systematically determined in our rheumatology outpatientclinic and classified in: vitamin D deficiency (< 10 μg/l),vitamin D insufficiency (10 to 30 μg/l) or normal vitamin D (> 30 μg/l).Patients with insufficiency or deficiency received respectively a singlehigh dose of 300'000 IU or 600'000 IU oral vitamin D3. In addition,all patients with osteoporosis were prescribed daily supplement ofcalcium (1 g) and vitamin D (800 IU). 25-OH vitamin D levels werereevaluated after 3 months.Results Vitamin D levels were initially determined in 292 patients(mean age 53, 211 women, 87 % Caucasian). 77 % had inflammatoryrheumatologic disease (IRD), 20 % osteoporosis (OP) and 12 %degenerative disease (DD). Vitamin D deficiency was present in 20(6.8 %), while 225 (77.1 %) had insufficiency. Of the 245 patientswith levels < 30μg/l, a new determination of vitamin D level wasavailable in 173 (71 %) at 3 months.Conclusion Vitamin D insufficiency is highly prevalent in ourrheumatologic population (84 %), and is not adequately correctedby a single high dose of oral vitamin D3 in > 50 % of the patientswith IRD and DD. In patients with OP, despite association of asingle high dose with daily oral vitamin D supplementation, 40 %of patients are still deficient when reevaluated at 3 months.
