Low Bone Mineral Density and the Risk of Benign Paroxysmal Positional Vertigo. Otolaryngol Head Neck Surg 2024; 170:877-885. [PMID: 38044484 DOI: 10.1002/ohn.600] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 10/19/2023] [Accepted: 11/02/2023] [Indexed: 12/05/2023]
Abstract
OBJECTIVE This study aimed to comprehensively analyze the relationship between low bone mineral density (BMD) and the risk of benign paroxysmal positional vertigo (BPPV) based on the large prospective population-based UK Biobank (UKB) cohort. STUDY DESIGN Prospective population-based cohort study. SETTING The UKB. METHODS This prospective cohort study included UKB participants recruited between 2006 and 2010 who had information on BMD and did not have BPPV before being diagnosed with low BMD. Univariable and multivariable logistic regression models were constructed to assess the association between low BMD (overall low BMD, osteopenia, and osteoporosis) and BPPV. We further conducted sex and age subgroup analysis, respectively. Finally, the effects of antiosteoporosis and female sex hormone medications on BPPV in participants with osteoporosis were evaluated. RESULTS In total, 484,303 participants were included in the final analysis, and 985 developed BPPV after a maximum follow-up period of 15 years. Osteoporosis was associated with a higher risk of BPPV (odds ratio [OR] = 1.37, P = .0094), whereas osteopenia was not. Subgroup analyses suggested that the association between osteoporosis and BPPV was significant only in elderly females (≥60 years, OR = 1.51, P = .0007). However, no association was observed between antiosteoporosis or female sex hormone medications and BPPV in the participants with osteoporosis. CONCLUSION Osteoporosis was associated with a higher risk of developing general BPPV, especially in females aged ≥ 60 years old, whereas osteopenia was not associated with BPPV.

Abstract
Reactive oxygen species (ROS) were formerly known as mere byproducts of metabolism with damaging effects on cellular structures. The discovery and description of NADPH oxidases (Nox) as a whole enzyme family that only produce this harmful group of molecules was surprising. After intensive research, seven Nox isoforms were discovered, described and extensively studied. Among them, the NADPH oxidase 3 is the perhaps most underrated Nox isoform, since it was firstly discovered in the inner ear. This stigma of Nox3 as "being only expressed in the inner ear" was also used by me several times. Therefore, the question arose whether this sentence is still valid or even usable. To this end, this review solely focuses on Nox3 and summarizes its discovery, the structural components, the activating and regulating factors, the expression in cells, tissues and organs, as well as the beneficial and detrimental effects of Nox3-mediated ROS production on body functions. Furthermore, the involvement of Nox3-derived ROS in diseases progression and, accordingly, as a potential target for disease treatment, will be discussed.

Abstract
OBJECTIVE Osteoporosis is a chronic systemic disease characterized by low bone mass, progressive microarchitectural deterioration and increased bone fragility. Hearing loss and benign paroxysmal positional vertigo (BPPV) have been found in patients diagnosed with osteoporosis over 65 years, however, there is lack of information about these conditions in young patients. Herein, we conducted a systematic review and meta-analysis to provide evidence of the association between osteoporosis and audio-vestibular findings in young subjects. METHODS Systematic review and meta-analysis were performed according to PRISMA guidelines. Searches were conducted in PubMed, Embase, and Web of Science Core Collection. Mean age, proportion of patients with low mineral density, hearing loss, and BPPV were calculated for the systematic review and meta-analysis. Odds Ratio (OR) with their corresponding 95% confidence intervals (CI) were calculated. RESULTS A total of 26 articles were reviewed. Only 10 studies met inclusion criteria for the meta-analysis. Six were assessed pursuing the association between osteoporosis and hearing loss. Pooled evidence suggested in patients with osteoporosis, an increased risk for developing hearing loss (OR = 1.52, 95% CI 1.06-2.19; P = .02) compared to controls. Another 6 studies reported the association between osteoporosis and BPPV. A significant increased risk for BPPV was found in individuals with osteoporosis (OR = 1.58, 95% CI 1.02-2.4; P = .04). There was no publication bias. CONCLUSION Subjects younger than 65 years with osteoporosis have an increase odds for hearing loss and BPPV compared to controls. These conditions could be associated with early inner or middle ear bone morphologic changes.

Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) is the most frequently diagnosed type of peripheral vestibular vertigo. Studies have reported a possible association between BPPV and osteoporosis; however, there is still a lack of evidence. This study aimed to investigate the characteristics of bone mineral density (BMD) and bithermal caloric test results in patients with unilateral posterior canal idiopathic benign paroxysmal positional vertigo (pc-iBPPV). METHODS BMD was measured in 65pc-iBPPV menopausal female patients and 65 healthy controls using dual-energy xray absorptiometry and then compared the T-score of BMD between the two groups. The bithermal caloric test was also performed with video nystagmography and the relationship between canal paresis, directional preponderance, T-score, and recurrence were analyzed. RESULTS Lower T-scores were observed in pc-iBPPV patients compared with the normal subjects. Among 65 pc-iBPPV patients, free recurrence was observed in 38 (58.5%), single recurrence was noted in 14 (21.5%), and multiple recurrences were seen in 13 (20%) patients. The proportion of positive T-score and CP value increased with the pc-BPPV recurrence frequency. Statistically, a significant difference was found only in T-score, indicating that recurrence was raised with a decrement of T-score. The proportion of positive CP values tended to increase as BMD decreased. CONCLUSION The decrement of BMD might be one of the pathogeneses in patients with unilateral pc-iBPPV and associated with multiple recurrences. Moreover, positive CP value cannot be regarded as a predictive factor for recurrence; however, there is a clear association between CP and BMD.

Abstract
OBJECTIVES Several studies have reported an association between benign paroxysmal positional vertigo (BPPV) and bone mineral density or serum vitamin D levels. The aim of this review is to provide further clarification regarding the relationship between BPPV and calcium metabolism. DESIGN PubMed and MEDLINE databases were systematically reviewed to identify all English language papers regarding the relationship between BPPV and the following terms: osteoporosis, osteopenia, bone mineral density, serum vitamin D levels, and bone metabolism. RESULTS Of the 456 identified records, 28 studies were eligible for this review. Most were retrospective studies with inherent limitations and often conflicting results. While the literature is not conclusive, osteoporosis in patients of at least 50 years old appears to have an association with BPPV. Similarly, an association was observed between recurrent BPPV and vitamin D deficiency. CONCLUSION There is only weak evidence to support the relationship between BPPV and osteoporosis or low serum 25-hydroxyvitamin D levels. Further prospective studies with more robust methodologies are needed to clarify the association between BPPV and disorders of bone metabolism.

Abstract
OBJECTIVE The association between benign paroxysmal positional vertigo (BPPV) and impaired calcium metabolism has attracted widespread interest. Several studies have suggested that decreased bone mineral density (BMD) and serum 25-hydroxyvitamin D (25(OH)D) level are related to the occurrence and/or recurrence of BPPV; however, the characteristics of bone metabolism in patients with BPPV subtypes have not been fully investigated, and conclusions have been controversial. This study aimed to evaluate BMD and serum levels of 25(OH)D and bone turnover markers to clarify the characteristics of bone metabolism in patients with different types of BPPV. METHOD We retrospectively analysed the data of new-onset idiopathic postmenopausal female patients with BPPV at our institution from January 2016 to January 2020. The patients' demographic data including age, medication history, concomitant diseases, onset time, clinical form, laboratory indicators, such as serum levels of 25(OH)D, bone formation markers, namely, amino-terminal propeptide of type I procollagen (PINP) and osteocalcin (OC), bone resorption marker, namely, β-isomerized carboxy-terminal telopeptide of type I collagen (β-CTX), and BMD were collected and analysed. RESULTS This study included 201 consecutive postmenopausal female patients with BPPV. Among them, 138 were diagnosed with posterior semicircular canal BPPV, 42 were diagnosed with lateral semicircular canal canalolithiasis, and 21 were diagnosed with lateral semicircular canal cupulolithiasis. There were no significant differences in age distribution, body mass index, clinical history, levels of albumin, globulin, uric acid, creatinine, or blood urea nitrogen, lipid profiles (except high-density lipoprotein cholesterol) and routine blood parameters among these groups (P > 0.05). There were no significant differences in the mean T-score and BMD values of different sites or in the serum levels of 25(OH)D and bone turnover markers (PINP, OC and β-CTX) among the subgroups (P > 0.05). The proportion of reduction in BMD (T-score < -1 SD) and decreased serum vitamin D level (< 20 ng/ml) were not significantly different between the subgroups (P > 0.05). CONCLUSION There were no significant differences in bone metabolism in postmenopausal female patients with different types of idiopathic BPPV.

Abstract
Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vertigo‑associated disease. Vitamin D (VD) helps maintain normal otolith function and may be associated with BPPV. VD exerts its biological functions primarily via the VD receptor (VDR). The present study demonstrated that serum VD levels were significantly decreased in patients with BPPV compared with in controls. VDR, otolith‑associated protein otoconin‑90 (OC90) and NADPH oxidase 3 (NOX3) expression levels were also significantly decreased in patients with BPPV compared with in controls. Furthermore, a positive correlation was observed between VD levels and VDR expression. Receiver operating characteristic curve analysis identified VDR expression levels as a potential diagnostic marker for BPPV. OC90 and NOX3 expression levels were notably lower in the inner ear tissue of VDR knockout mice compared with in those of wild‑type mice. In mice overexpressing VDR, OC90 and NOX3 were also overexpressed. Following intravenous injection of VD in VDR knockout mice, expression levels of OC90 and NOX3 were not significantly different from those in VDR knockout mice injected with saline. This indicated that VDR may be underexpressed in patients with BPPV and was associated with the expression levels of otolith‑associated proteins. Moreover, VDR mediated VD activation, leading to otolith protein formation. The present study provided a novel theoretical basis for BPPV onset that may facilitate the development of more effective diagnostic and treatment options.

Abstract
OBJECTIVE This study aimed to evaluate the association between serum vitamin D levels and benign paroxysmal positional vertigo (BPPV). PARTICIPANTS AND METHODS This prospective study consisted of 137 participants. There were 69 participants in the BPPV group compared with 68 healthy participants. Blood samples from both groups were collected from all participants to assess serum vitamin D levels. RESULTS No significant difference in demographic data between BPPV and control groups. The results showed that the mean serum vitamin D levels in the BPPV group was lower than that of the control group (P value = .001). Among BPPV participants, there was no statistically significant difference between mean serum vitamin D levels of participants with recurrent BPPV, and that of newly diagnosed BPPV participants (P value = .313). CONCLUSION A statistically significant association between lower mean serum vitamin D levels in the BPPV group compared with that of the control group. Therefore, low serum vitamin D levels may be one of the risk factors for BPPV.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) has a reported recurrence ranging from 26.8 to 50%. Osteoporosis and Vitamin D deficiency seems to have an impact on recurrence of BPPV. OBJECTIVE to evaluate the impact of osteoporosis and Vitamin D deficiency on recurrence of BPPV. METHODS 73 consecutive patients were divided in two groups according to the presence (group 1) or absence (group 0) of a recurrent episode. BMD, femoral and lumbar T-scores and Vitamin D levels were recorded. Statistical analysis was performed to investigate correlations. RESULTS patients in group 1 had statistically significant lower values of both femoral (-1,62±1,06 vs. -0,53±1,51; p = 0,001), lumbar T-score (-2,10±1,19 vs -0, 53±1.51, p = 0.001) and Vitamin D (19.53±15.33). The values of femoral T-score and Vitamin D could be combined in a model able to properly classify 65.8% of the cases (p = 0.002) as isolated or recurrent BPPV, with high accuracy (AUC 0.710 [0.590 -0.830]). CONCLUSION present data show a probable correlation between osteoporosis and Vitamin D with recurrent BPPV.

Abstract
Neurological diseases, particularly in the context of aging, have serious impacts on quality of life and can negatively affect bone health. The brain-bone axis is critically important for skeletal metabolism, sensory innervation, and endocrine cross-talk between these organs. This review discusses current evidence for the cellular and molecular mechanisms by which various neurological disease categories, including autoimmune, developmental, dementia-related, movement, neuromuscular, stroke, trauma, and psychological, impart changes in bone homeostasis and mass, as well as fracture risk. Likewise, how bone may affect neurological function is discussed. Gaining a better understanding of brain-bone interactions, particularly in patients with underlying neurological disorders, may lead to development of novel therapies and discovery of shared risk factors, as well as highlight the need for broad, whole-health clinical approaches toward treatment.

Abstract
ObjectiveTo assess the effect of vitamin D and calcium supplementation in preventing recurrences of benign paroxysmal positional vertigo (BPPV).MethodsWe performed an investigator-initiated, blinded-outcome assessor, parallel, multicenter, randomized controlled trial in 8 hospitals between December 2013 and May 2017. Patients with confirmed BPPV were randomly assigned to the intervention (n = 518) or the observation (n = 532) group after successful treatment with canalith repositioning maneuvers. The primary outcome was the annual recurrence rate (ARR). Patients in the intervention group had taken vitamin D 400 IU and 500 mg of calcium carbonate twice a day for 1 year when serum vitamin D level was lower than 20 ng/mL. Patients in the observation group were assigned to follow-ups without further vitamin D evaluation or supplementation.ResultsThe intervention group showed a reduction in the ARR (0.83 [95% confidence interval (CI), 0.74–0.92] vs 1.10 [95% CI, 1.00–1.19] recurrences per 1 person-year) with an incidence rate ratio of 0.76 (95% CI, 0.66–0.87, p < 0.001) and an absolute rate ratio of −0.27 (−0.40 to −0.14) from intention-to-treat analysis. The number needed to treat was 3.70 (95% CI, 2.50–7.14). The proportion of patients with recurrence was also lower in the intervention than in the observation group (37.8 vs 46.7%, p = 0.005).ConclusionsSupplementation of vitamin D and calcium may be considered in patients with frequent attacks of BPPV, especially when serum vitamin D is subnormal.Classification of evidenceThis study provides Class III evidence that for patients with BPPV, vitamin D and calcium supplementation reduces recurrences of BPPV.

Abstract
BACKGROUND AND PURPOSE Although acute attacks of benign paroxysmal positional vertigo (BPPV) may be treated with canalith repositioning maneuvers, there have been no well-designed prospective trials to prevent this highly prevalent and recurrent disorder. This topical review explores the evidence related to the association between deficient calcium metabolism and BPPV. We also describe the development of therapeutic options to prevent recurrences of BPPV and introduce results from a recent randomized controlled trial on the effect of vitamin D and calcium supplementation in preventing BPPV recurrences. SUMMARY OF KEY POINTS The literature describes 3 lines of evidence on association of impaired calcium metabolism and development of BPPV: (1) decreased bone mineral density was more frequently observed in persons with BPPV than in healthy controls; (2) estrogen plays a vital role in maintenance of otoconia, and estrogen deficiency appears to precipitate degeneration of otoconia and development of BPPV; and (3) lower serum vitamin D level is associated with development of BPPV, and supplementation of vitamin D and calcium carbonate may reduce further attacks of BPPV in persons with BPPV and subnormal serum vitamin D level. RECOMMENDATIONS FOR CLINICAL PRACTICE Restoration of impaired calcium metabolism with supplementation of vitamin D or estrogen should be considered in the treatment of individuals with frequent recurrences of BPPV. Future randomized controlled trials are mandatory to validate these supplementation therapies in individuals with recurrent BPPV.

Abstract
Background and Purpose: The lifetime prevalence of benign paroxysmal positional vertigo (BPPV) is high, especially in the elderly. Patients with BPPV are more susceptible to ischemic stroke, dementia, and fractures, severely reducing quality of life of patients. Many studies have analyzed risk factors for the occurrence of BPPV. However, the results of these studies are not identical. We performed this meta-analysis to determine potential risk factors associated with the occurrence of BPPV. Methods: PubMed, EMBASE, and the Cochrane Library (January 2000 through March 2020) were systematically searched for eligible studies analyzing risk factors for the occurrence of BPPV. Reference lists of eligible studies were also reviewed. We selected observational studies in English with a control group and sufficient data. Pooled odds ratios (ORs) or the mean differences (MDs) and 95% confidence intervals (CIs) were calculated to measure the impacts of all potential risk factors. Heterogeneity among studies was evaluated using the Q-test and I2 statistics. We used the random-effect model or the fixed-effect model according to the heterogeneity among the included studies. Results: We eventually included 19 studies published between 2006 and 2019, including 2,618 patients with BPPV and 11,668 participants without BPPV in total. In this meta-analysis, the occurrence of BPPV was significantly associated with female gender (OR = 1.18; 95% CI, 1.05–1.32; P = 0.004), serum vitamin D level (MD = −2.12; 95% CI, −3.85 to −0.38; P = 0.02), osteoporosis (OR = 2.49; 95% CI, 1.39–4.46; P = 0.002), migraine (OR = 4.40; 95% CI, 2.67–7.25; P < 0.00001), head trauma (OR = 3.42; 95% CI, 1.21–9.70; P = 0.02), and total cholesterol level (MD = 0.32; 95% CI, 0.02–0.62; P = 0.03). Conclusion: Female gender, vitamin D deficiency, osteoporosis, migraine, head trauma, and high TC level were risk factors for the occurrence of BPPV. However, the effects of other risk factors on BPPV occurrence need further investigations.

[PMID: 32477244 PMCID: PMC7237635 DOI: 10.3389/fneur.2020.00367] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Accepted: 04/14/2020] [Indexed: 12/11/2022] Open
Abstract
Objective: Otolin-1, a main specific otoconia matrix protein, passes through the labyrinth-blood barrier and is detectable in peripheral blood. Serum otolin-1 levels differ between patients with benign paroxysmal positional vertigo (BPPV) and healthy controls and are significantly age-related, increasing in healthy controls with age, suggesting that serum otolin-1 levels reflect otolith status. The aim of this study was to determine whether otolin-1 levels change during vertigo episodes in patients with BPPV and whether any change is specific and sensitive enough for BPPV episodes. Method: Patients diagnosed with de novo idiopathic BPPV during an acute episode were included in the study from May 2017 to May 2018. Blood samples were drawn before patients were treated with canalith-repositioning maneuvers. Serum otolin-1 levels were compared between 78 patients and 121 age- and sex-matched healthy individuals. Results: There were no significant differences between the groups in the age distribution, sex ratio, body mass index, clinical history, routine blood parameters, or total protein, albumin, uric acid, creatinine, blood urea nitrogen and lipid profiles (P > 0.05). Serum levels of otolin-1 were significantly higher in BPPV patients than in healthy controls (P < 0.001). Receiver operating characteristic analysis revealed that a serum otolin-1 value of 299.45 pg/ml was the optimal cut-off value to discriminate patients with BPPV from healthy controls (area under the curve 0.757, 95% CI 0.687~0.826) with a sensitivity of 67.9% and a specificity of 72.7%. Conclusion: Serum levels of otolin-1 may be a potential biomarker for BPPV episodes.

Abstract
OBJECTIVE Estrogen deficiency caused by bilateral ovariectomy (OVX) has been reported to lead to morphological changes in otoconia. Thus, we examined the morphological changes in the otoconial layer after OVX. We also investigated whether micro-computed tomography (µCT) is useful for the detection of morphological changes in the otoconial layer. METHODS The otic capsules of C57BL/6 J mice were removed and evaluated using histological techniques and µCT at 2, 4, and 8 weeks after OVX or sham surgery. The volume of the utricle otoconial layer was measured and compared between the OVX and sham groups. The µCT scan and histological study results were also compared. RESULTS The volume of the utricle otoconial layer was significantly increased 4 weeks after OVX compared to the sham group in both histological and µCT studies (p < 0.05). The volume of the otoconial layer measured using µCT was significantly correlated with the histological study results (p < 0.05). CONCLUSION The volume of the utricle otoconial layer increased after OVX. These morphological changes could be detected by µCT.

Abstract
Although the etiology of benign paroxysmal positional vertigo (BPPV) is idiopathic in most cases, the association of osteoporosis or vitamin D deficiency with BPPV has attracted much interest recently. While it is generally accepted that osteoporosis or vitamin D deficiency is related to the occurrence and/or recurrence of BPPV, the difference in serum vitamin D level and bone mineral density (BMD) among different subtypes of BPPV has not been investigated. We aimed to compare T-score of BMD score and serum 25-hydroxyvitamin D level among idiopathic BPPV patients with a different subtype. This study included 117 consecutive patients with idiopathic BPPV (26 men and 91 women; mean age, 55 ± 11 years; age range, 25 to 78 years) who underwent blood sampling for serum 25-hydroxyvitamin D level measurement and bone mineral densitometry of the anterior-posterior lumbar spine and femur between April 2018 and February 2019. Among 117 patients, 49 were diagnosed with posterior semicircular canal (PSCC) BPPV, 24 were diagnosed with lateral semicircular canal (LSCC) canalolithiasis, and 44 were diagnosed with LSCC cupulolithiasis. The mean T-score of BMD was -1.5 ± 0.9 in PSCC BPPV, -1.5 ± 1.3 in LSCC canalolithiasis, and -1.5 ± 1.1 in LSCC cupulolithiasis, which was not significantly different (p = 0.998, One-way ANOVA test). The mean level of 25-hydroxyvitamin D was 22.5 ± 10.6 ng/ml in PSCC BPPV, 26.8 ± 16.0 ng/ml in LSCC canalolithiasis, and 25.4 ± 9.6 ng/ml in LSCC cupulolithiasis, which was not significantly different (p = 0.262, One-way ANOVA test). The proportion of osteoporosis/osteopenia or vitamin D deficiency/insufficiency did not show significant difference among idiopathic BPPV patients with different subtypes, and findings of this study indicate that either serum level of vitamin D or T-score of BMD is not a distinguishable characteristic among different subtypes of BPPV.

Abstract
Objective: Vestibular neuritis (VN) is characterized by acute onset of vertigo, nausea, and vomiting, without auditory or other neurological symptoms. Although the pathogenesis of VN is not yet clear, many studies have shown that a pro-inflammatory environment can lead to the induction and progression of the disease. Considering the importance of vitamin D in modulating the activation, proliferation, and differentiation of inflammatory physiological processes, we hypothesized that decreased serum vitamin D may be associated with the development of VN. In this study, we evaluated serum levels of 25-hydroxyvitamin D [25(OH)D] in patients presenting acutely with VN and healthy controls and investigated the possible correlation of serum 25(OH)D levels with VN. Methods: A total of 59 consecutive patients diagnosed with VN within 7 days of symptom onset and 112 age- and sex-matched healthy controls referred to Hwa Mei Hospital, University of Chinese Academy of Science, between March 2017 and March 2019 were recruited. Demographic and clinical data, such as age, sex, height, weight, living habits, ongoing health problems, and medication history, for all subjects were recorded, and levels of 25(OH)D were measured and compared. Results: Serum levels of 25(OH)D were lower in patients with VN than in controls (19.01 ± 6.53 vs. 22.94 ± 6.74 ng/ml, p < 0.001). Patients with VN had a higher frequency of vitamin D deficiency (61.0 vs. 34.8%, P = 0.001) than did controls. Regression analyses demonstrated that vitamin D deficiency was associated with VN, with an odds ratio of 4.53 (95% CI = 1.342–15.279, P = 0.015). Conclusion: This prospective study is the first to evaluate serum 25(OH)D levels in patients with VN and found that decreased serum 25(OH)D may be associated with VN occurrence.

Abstract
PURPOSE To investigate the relationship between cerebrovascular risk factors, including carotid plaques, and vestibular neuritis (VN). MATERIALS AND METHODS According to the inclusion and exclusion criteria, this retrospective study included 90 VN patients and 74 age- and sex-matched healthy controls from January 2016 to December 2017. All subjects' records of cerebrovascular risk factors, such as age, sex, height, weight, history of hypertension and diabetes mellitus, living habits, serum levels of glucose, lipids, glycosylated haemoglobin (HbA1c), creatinine (CR), albumin (ALB), haemoglobin (HGB); and results of carotid colour Doppler ultrasound, were obtained and compared. RESULTS No significant differences in age; sex ratio; body mass index; history of hypertension or diabetes mellitus; or mean serum lipids, glucose, creatinine, haemoglobin or HbA1c were found between patients with VN and healthy controls (all P > 0.05). The mean serum ALB level was significantly lower in VN patients than in healthy controls (40.65 ± 3.77 vs 42.84 ± 4.32, P = 0.001).The prevalence of carotid plaques was significantly higher in VN patients than in healthy controls (36.67% vs. 16.22%, P = 0.003). Regression analyses demonstrated that a high frequency of carotid plaques was associated with VN with an odds ratio of 2.252 (95% CI 1.165-5.458, P = 0.019). CONCLUSION A high frequency of carotid plaques may be a risk factor for VN.

Abstract
Objective: Several studies have suggested a probable association between benign paroxysmal positional vertigo (BPPV) and both reduction of bone mineral density (BMD) and serum vitamin D levels, but none of these studies have explored their findings by examining bone turnover markers (BTM) in male idiopathic BPPV patients. This study aimed to evaluate the relationship between BMD and serum 25-hydroxyvitamin D (25(OH) D), with the occurrence of BPPV along with the characteristics of bone metabolism in male idiopathic BPPV patients. Methods: This retrospective study comprised 60 male idiopathic BPPV patients and 92 age-matched healthy controls referred to Ningbo No.2 Hospital during the period of February 2016 to February 2018. All subjects' serum levels of 25(OH) D, bone formation marker amino-terminal propeptide of type I procollagen (PINP), and bone resorption marker β-isomerized carboxy-terminal telopeptide of type I collagen (β-CTX) were measured. BMD was determined by dual energy X-ray absorption at the lumbar spine and hip. Results: Among male patients with BPPV, the prevalence of BMD reduction was 35.0%, which was similar to that of 27.2% in healthy controls. There were significant differences in the mean serum 25(OH) D level and prevalence of vitamin D deficiency between the two groups, with p-values of 0.049 and 0.009, respectively. The bone turnover markers of PINP and β-CTX in BPPV patients were lower than those in healthy controls. Logistic regression showed that vitamin D deficiency were associated with BPPV with an odds ratio of 3.8 (95% confidence interval = 1.25-11.73). Conclusion: Our study found that decreased serum vitamin D may be a risk factor for BPPV in male patients. The level of bone turnover among male patients with BPPV was lower than that among healthy controls.
