Relation between vitamin D deficiency and benign paroxysmal positional vertigo.

Area of Science:

• Neurology
• Endocrinology
• Otolaryngology

Background:

• Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo.
• Vitamin D deficiency is increasingly recognized as a potential contributing factor in BPPV development and recurrence.

Purpose of the Study:

• To investigate the relationship between recurrent BPPV episodes and vitamin D deficiency.
• To evaluate the efficacy of vitamin D supplementation in preventing BPPV recurrence.

Main Methods:

• A case-control study involving 40 patients diagnosed with posterior canal BPPV.
• Patients were divided into two groups: one receiving canal repositioning maneuver plus vitamin D supplementation (Group A), and the other receiving only the maneuver (Group B).
• Serum 25(OH)D levels were measured at baseline and after 6 months, with neuro-otological assessments and recurrence monitoring throughout the follow-up period.

Main Results:

• All participants presented with low serum 25(OH)D levels (below 20 ng/ml) at the initial visit.
• Group A, which received vitamin D supplementation, showed significantly fewer recurrent BPPV episodes compared to Group B.
• A clear association was observed between low serum vitamin D levels and increased BPPV recurrence.

Conclusions:

• Low serum vitamin D levels are linked to a higher incidence of recurrent benign paroxysmal positional vertigo.
• Vitamin D supplementation, in conjunction with canal repositioning maneuvers, appears to be an effective strategy for reducing BPPV recurrence.
