Correlations of Calcium Voltage-Gated Channel Subunit Alpha1 A (CACNA1A) Gene Polymorphisms with Benign Paroxysmal Positional Vertigo.

ABSTRACT: BACKGROUND The aim of this study was to investigate the correlations of calcium voltage-gated channel subunit alpha1 A (CACNA1A) gene polymorphisms with benign paroxysmal positional vertigo (BPPV). MATERIAL AND METHODS A total of 120 BPPV patients and 60 healthy controls were enrolled according to the diagnostic criteria in the Guideline of Diagnosis and Treatment of Benign Paroxysmal Positional Vertigo (2017). Clinical and biochemical data were collected, the rs2074880 (T/G) polymorphisms in the CACNA1A gene were detected using TaqMan-MGB probe method, and the correlations of BPPV with predisposing factors were analyzed through logistic analysis. RESULTS The BPPV group had higher levels of cholesterol and uric acid than in the control group (p<0.05). The cholesterol and uric acid levels were positively correlated with BPPV (p<0.05) [odds ratio (OR)=2.298 (1.252-4.350), 95% confidence interval (95% CI)=1.123 (0.987-1.987)]. The distribution frequency of TT genotype was higher than that of GG genotype (?²=9.907, p=0.002, OR=0.279, 95% CI=0.123-0.633). In the BPPV group, cholesterol and uric acid levels of TT genotype were elevated compared with those in GG genotype (p<0.05). CONCLUSIONS The onset of BPPV is related to the increased levels of cholesterol and uric acid, as well as the dominant homozygous mutation of rs2074880 (T/G) in the CACNA1A gene.

Project description:BACKGROUND:Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo. Little is known on how posterior canal BPPV affects health-related quality of life in patients diagnosed and treated at primary care facilities or on whether patients with subjective and objective disease perceive the effects differently. This study was designed to describe how patients diagnosed with posterior canal BPPV in primary care perceive disability. METHODS:Cross-sectional descriptive study performed at two urban primary care centers. Participants were patients aged 18?years or older with suspected posterior canal BPPV recruited for baseline evaluation in a clinical trial on the effectiveness of the Epley maneuver in primary care. The recruitment period was from November 2012 to January 2015. Perceived disability was evaluated using the Dizziness Handicap Inventory - Screening version (DHI-S). Other variables collected were age and sex, a history or diagnosis of anxiety or depression, treatment with antidepressants and/or anxiolytics, and results of the Dix-Hallpike (DH) test, which was considered positive when it triggered vertigo with or without nystagmus and negative when it triggered neither. RESULTS:The DH test was positive in 134 patients, 40.30% of whom had objective BPPV (vertigo with nystagmus). The median age of the patients was 52?years (interquartile range [IQR], 39.00-68.50?years) and 76.1% were women. The median total score on the DHI-S was 16 out of 40 (IQR, 8.00-22.00). Scores were higher (greater perceived disability) in women (p <?0.001) and patients with subjective BPPV (vertigo without nystagmus) (p =?0.033). The items perceived as causing the greatest disability were feeling depressed (67.1%) and worsening of the condition on turning over in bed (88%). CONCLUSIONS:Patients diagnosed with posterior canal BPPV in primary care perceive their condition as a disability according to DHI-S scores, with higher levels of disability reported by women and patients with subjective BPPV. Feelings of depression and turning over in bed were associated with the greatest perceived difficulties. TRIAL REGISTRATION:ClinicalTrials.gov Identifier: NCT01969513. Retrospectively registered.
