Osteoporoza kao čimbenik rizika za razvoj benigne paroksizmalne položajnevrtoglavice

Objectives: The aim of this study is to examine the association of vitamin D levels, ionized calcium, and densitometry findings with the onset of BPPV. Participants and methods: A cross-sectional study was conducted, including 40 subjects over the age of 18 who were diagnosed with BPPV based on a positive result of the Dix-Hallpike maneuver. Clinical assessments were performed by an otorhinolaryngology specialist. Subjects with a confirmed diagnosis of BPPV were further referred for laboratory tests to measure vitamin D levels, ionized calcium in the blood, and bone densitometry. Results: Out of 40 subjects, 37 (93%) were women, and 3 (7%) were men. In all cases, the posterior semicircular canal was involved. The right side was affected in 23 subjects (58%). Osteopenia and osteoporosis were recorded in 34 subjects (85%). Reference range values for vitamin D were recorded in 19 subjects (4%), while ionized calcium levels were within the reference range in 7 subjects (18%). Sixteen subjects (40%) had both values within the reference range. No significant associations were found between gender, clinical form, or affected side and the values of vitamin D, calcium, or densitometry findings. Conclusion: However, an association was observed between the presence of osteoporosis and BPPV, suggesting that osteoporosis may be a risk factor for the development of BPPV. The study could not establish the influence of low vitamin D or ionized calcium levels on the development of BPPV. Further research is needed to better understand these potential relationships.
