Chua KWD, Huang X, Koh XH, Soh JFJY, Barrera VC, Anaikatti P, Jing D, Moh S, Yeo M, Yuen HW, Low D, Rosario BH. Randomized Controlled Trial Assessing Vitamin D's Role in Reducing BPPV Recurrence in Older Adults. Otolaryngol Head Neck Surg 2024. [PMID: 39194424 DOI: 10.1002/ohn.954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 07/30/2024] [Accepted: 08/10/2024] [Indexed: 08/29/2024]
Abstract
OBJECTIVE To determine if the recurrence rates of BPPV in older adults were lower in the vitamin D-treated group as compared to placebo groups. STUDY DESIGN Double-blinded randomized control placebo trial. SETTING A single-centre study. METHODS Double-blinded randomized controlled trial design with 12 months follow-up. Vitamin D3 deplete participants were randomized into treatment (Group A) or placebo groups (Group B). Treatment group received 13 weeks of 2000 IU vitamin D3 followed by 1000 IU for the next 13 weeks. Patients who were replete were allocated to a control group (Group C) for observation and follow up. All groups had dietary interventions for vitamin D3 and calcium. RESULTS Results showed an 87% reduction in recurrence rates of BPPV in the treatment group (Group A), with 0.75 fewer clinical episodes per 1 person-year as compared to placebo (Group B). Time to first recurrence was also significantly longer in Group A. There was no statistically significant difference between Group A and C in both recurrence rates and dizziness handicap scores. CONCLUSIONS This clinical trial has laid the foundation to expand the investigation of vitamin D as standard of care treatment in BPPV patients in future phase IIb and III studies. SUMMARY A reduction in BPPV episodes in older adults has implications on fall risk, as dizziness from BPPV may cause falls. With fewer BPPV episodes and longer time to recurrence, seniors may have better postural stability and hence reduced risk of falls. LEVEL OF EVIDENCE: 2

Audiol Res 2024; 14:640-648. [PMID: 39051198 PMCID: PMC11270364 DOI: 10.3390/audiolres14040054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 06/17/2024] [Accepted: 06/22/2024] [Indexed: 07/27/2024] Open
Abstract
OBJECTIVE This study's objective was to identify the factors and impact of serums calcium 25-Hydroxy vitamin D, ferritin, uric acid, and sleeping disorders on benign paroxysmal positional vertigo (BPPV) patients. METHODS This is a case and control design study. The consecutive patients' visits (age, older than 25 years) with idiopathic BPPV were recruited in the present study. For each patient, 3:1 sex and age-matched healthy people were assigned as the control. The study comprised 177 patients with BPPV and 656 controls. The study included biochemical, clinical, physical examinations, PSQI sleep quality, supine roll test, and Dix-Hallpike test for the diagnosis of all patients, and pure-tone audiometry (PTA) was used to assess hearing. Univariate and multivariate stepwise regression analyses were used for statistical analysis. RESULTS The study comprised 833 patients with 295 males (35.4%) and 538 females (64.6%) who were between 25 and 70 years old. Of a total of 833 participants, 177 were BPPV patients, and 656 subject were normal. The results shown that there were significant differences between the BPPV and the normal group in terms of BMI (p = 0.039), physical activity (p = 0.003), cigarette smoking (p = 0.035), nargile-waterpipe use (p < 0.001), diabetes (p < 0.001), hypertension (p < 0.001), congestive heart failure (CHF) (p < 0.001), neurology (p < 0.001), tinnitus (p < 0.001), dizziness (p < 0.001), headache (p < 0.001), vitamin D (p = 0.004), calcium (p = 0.004), magnesium (p < 0.001), potassium (p = 0.019), phosphorus (p < 0.001), haemoglobin (p < 0.001), serum glucose (p < 0.001), HbA1c (p < 0.001), triglyceride (p < 0.001), systolic BP (p = 0.004), diastolic BP (p = 0.008), and microalbuminuria (p = 0.005); ATP III metabolic syndrome (p = 0.038), IDF metabolic syndrome (p = 0.034), and poor sleep (p = 0.033). In terms of the type of BPPV, the posterior canal was the most commonly affected (n = 126, 71.2%), followed by the horizontal (n = 43, 24.3%) and anterior canal (n = 8, 4.5%). The analysis indicated that serum ferritin (p < 0.001), uric acid (p < 0.001), blood pressure (p < 0.001), dizziness (p < 0.001), cigarette-water-pipe smokers (p = 0.004), headaches/migraines (p = 0.005), calcium (p = 0.007), vitamin D deficiency (p = 0.008), sleepiness (p = 0.016), physical activity (p = 0.022), CHF (p = 0.024), and tinnitus (p = 0.025) were considered as risk predictors for BPPV. CONCLUSIONS The results revealed that the serum levels of vitamin D, ferritin, uric acid, and calcium are low among the study population and supplementation could be considered as prevention in BPPV patients.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular condition characterized by short-term vertigo attacks that significantly affect quality of life. OBJECTIVES Examine how well a single Epley maneuver worked in an outpatient setting for people with posterior canal benign paroxysmal positional vertigo (PC-BPPV) and whether they needed a second Dix-Hallpike maneuver. DESIGN Prospective. SETTINGS Otorhinolaryngology department of a tertiary care center. PATIENTS AND METHODS Sociodemographic data, body mass index (BMI), and systemic disease history of 75 patients diagnosed with PC-BPPV were recorded, and their relationship with success rates after the modified Epley maneuver was analyzed. MAIN OUTCOME MEASURES Detect cases that could not be repositioned with the diagnostic control Dix-Hallpike test performed 20 minutes after the modified Epley reposition maneuver in the same session in PC-BPPV patients. SAMPLE SIZE 75. RESULTS Of the 75 patients, 31 were male (41.3%), 44 female (58.6%) with a mean (standard deviation) age of 58.6 (15.9) years age, 54.6% had one or more chronic diseases. BMI was 30 mg/kg2 and above in 31 patients (41.3%). The modified Epley maneuver was successful in 77.3%. No significant relationship was found between additional diseases or BMI in the patient group in whom the maneuver was unsuccessful. CONCLUSION The success rates of repositioning maneuvers in treating patients diagnosed with PC-BPPV are high. However, more than a single maneuver is required in some resistant patients. Second diagnostic and repositioning maneuvers performed in the same session will reduce multiple hospital admissions. While it is helpful to repeat the maneuver in the patient group where it was unsuccessful, other factors causing the failure should be investigated. LIMITATIONS Lack of follow-up results of patients after 7-10 days.

Abstract
PURPOSE This study aimed to investigate the vitamin D deficiency of patients with BPPV recurrence and to evaluate the differences of 25-hydroxy vitamin D (25(OH)D) and serum calcium levels among gender and age categories. METHODS This cross-sectional study enrolled patients with BPPV. The diagnosis of BPPV was based on positional nystagmus and vertigo induced by certain head positions (The Dix-Hallpike maneuver and head roll tests). All patients' age, serum 25(OH)D, calcium measurements and recurrence data were collected and analyzed. RESULTS The median of 25(OH)D was 15.32 (IQR 10.61, 20.90) ng/ml. The recurrent group showed lower 25(OH)D levels than that of non-recurrent group [13.28 (IQR 9.47, 17.57) ng/ml vs 16.21 (IQR 11.49, 21.13) ng/ml]. There were significant differences of 25(OH)D levels among age categories. The proportion of vitamin D deficiency in patients ≥60 years old was lower than that in the other two groups. CONCLUSION Our study suggested that BPPV patients had a decreased 25(OH)D level and a high incidence of vitamin D deficiency. The 25(OH)D level of recurrent BPPV patients was lower than that in non-recurrent ones. Among them, the elderly group (≥60 years) took the preponderance, which had the lowest incidence of vitamin D deficiency and the highest incidence of vitamin D sufficiency.

Abstract
We report a case of non-traumatic, multicanal benign paroxysmal positional vertigo (BPPV) in a premenopausal, osteopenic 35-year-old female with corresponding low bone mineral density. Dix-Hallpike and supine roll tests confirmed unilateral posterior canal (PC) BPPV from 2012-2014, and later, a rare presentation of multicanal BPPV with specifically ipsilateral horizontal canals (HC) and anterior canals (AC) affected in 2015. Heel scans displayed T-scores within the osteopenia range in 2012 until levels normalized one year later. Despite treatment with indicated canalith repositioning treatments (CRTs), symptoms continued to persist. Complete resolution of symptoms occurred in 2016, which is most likely due to self-treatment with daily 5000 IU vitamin D in 2015. This case emphasizes the rare presentation of unilateral single-canal BPPV to multi-canal BPPV, along with the importance of vitamin D treatment in preventing the recurrence of symptoms.

Abstract
Positional vertigo manifests as a spinning sensation triggered by changes in head position relative to gravity. Benign paroxysmal positional vertigo (BPPV) is an inner ear disorder characterized by recurrent episodes of positional vertigo. The connection between vitamin D insufficiency/deficiency and the onset and recurrence of BPPV is established. This study aims to assess vitamin D as a recurring factor in BPPV and the efficacy of vitamin D supplementation in preventing its recurrence. A comprehensive literature review on the relationship between vitamin D and BPPV recurrence was conducted, searching PubMed, Embase, Web of Science, and article reference lists for studies published from 2020 to 2023. A total of 79 articles were initially identified through the search, with 12 of them being utilized in the study. Recurrence rates for BPPV varied from 13.7% to 23% for studies with follow-up less than 1 year and 13.3% to 65% for studies with follow-up equal to or exceeding 2 years. Risk factors for BPPV recurrence include advanced age, female sex, hypertension, diabetes mellitus, hyperlipidemia, osteoporosis, and vitamin D deficiency. While earlier studies did not establish a link between low vitamin D levels and initial BPPV occurrence, they did associate recurrent episodes with low vitamin D levels. Recent research indicates that vitamin D supplementation in BPPV patients with deficiency or insufficiency decreases both the numbers of relapsing patients and relapses per patient. To validate these findings across diverse populations, further randomized controlled studies with larger cohorts and extended follow-up durations are essential.

Abstract
Objective To evaluate the effect of vitamin D supplementation on the recurrence rate of benign paroxysmal positional vertigo (BPPV). Methods A single-center, prospective, double-blind, placebo-controlled, parallel-group randomized controlled trial was conducted between November 2018 and May 2020. After successful treatment with canalith repositioning maneuvers, patients diagnosed with BPPV were randomized to either the vitamin D (n = 20) or placebo (n = 18) group. Only patients with serum vitamin D levels <20 ng mL-1 were included. The vitamin D group received 7000 IU of vitamin D weekly for a year, while the placebo group received a matching placebo drug. The final endpoint was the BPPV recurrence rate and correlation with serum vitamin D levels after 6 and 12 months in both groups. Results Among 38 patients, 37 were followed up for 6 months and 30 for 12 months. Significantly higher serum vitamin D levels were observed in the vitamin D group compared to the placebo group at both the 6-month and 1-year follow-ups (p < .001 at each timepoint). The recurrence rate was lower in the vitamin D group than in the placebo group after 6 months (p = .008) and 1 year (p = .003). Conclusion Vitamin D supplementation, in the absence of calcium, may be beneficial for patients prone to recurrent BPPV episodes, particularly when serum vitamin D levels are suboptimal (PRE20181024-001, Clinical Research Information Service, South Korea). Level of Evidence 1b.

Abstract
Ménière's disease (MD) is characterized by an abnormal dilatation of the endolymphatic compartment called endolymphatic hydrops and is associated with fluctuating hearing losses and vertigo. Corticosteroid treatment is typically administered for its anti-inflammatory effects to MD patients. However, we recently described for the first time a direct interaction of two corticosteroids (dexamethasone and cortisol) with human AQP2 which strongly inhibited water fluxes. From these initial studies, we proposed an AQPs Corticosteroids Binding Site (ACBS). In the present work, we tested the interaction of 10 molecules associated to the steroid family for this putative ACBS. We observed a wide diversity of affinity and inhibitory potential of these molecules toward AQP2 and discussed the implications for inner ear physiology. Among the tested compounds, cholecalciferol, calcitriol and oestradiol were the most efficient AQP2 water permeability inhibitors.

Abstract
Background and objectives: Osteoporosis and vitamin D3 deficiency may be risk factors of benign paroxysmal positional vertigo (BPPV). The aim of this study was to assess the prevalence of osteoporosis and 25(OH) vitamin D3 deficiency in a group of patients with idiopathic benign paroxysmal positional vertigo. Materials and Methods: Thirty-five patients (twenty-eight women and seven men) with posterior semicircular canal BPPV were enrolled in the study. The subjects underwent hearing assessment (tonal audiometry and impedance audiometry) and the Dix-Hallpike maneuver. Serum 25(OH) vitamin D3 levels were determined and lumbar spine bone densitometry was performed. The relationships between sex, age, height, Body Mass Index (BMI), vitamin D3 levels and bone densitometry results were assessed. Results: The diagnosis of osteoporosis was confirmed in 1 patient (3%), 3 subjects were osteopenic (8.6%), and normal bone densitometry was found in 31 (88.6%) patients. Conclusions: We found no statistically significant relationships between age, BMI or vitamin D3 levels and bone densitometry results in patients with idiopathic BPPV.

Abstract
OBJECTIVE To determine the value of a questionnaire as a screening tool for benign paroxysmal position vertigo (BPPV). STUDY DESIGN Retrospective chart review. SETTING Tertiary care centers. METHODS A total of 520 vertigo adults completed the questionnaire before the diagnosis was confirmed. After vestibular function examination and other diagnostic examination, the diagnosis of all participants was confirmed by experts. By validating valuable items from the questionnaire with 47 items, a new questionnaire of 5 items was formed to quickly diagnose BPPV. The internal consistency of the new questionnaire and validity were evaluated. The correlation between the score obtained from the new questionnaire and diagnosis was investigated. The mean score was also compared between groups with and without BPPV and diagnostic precision measures were calculated. RESULTS 520 vertigo participants answered all the question completely and BPPV was identified in 138 participants (26.5%). The responses to questionnaire revealed preferable reproducibility (r = 0.898, P < 0.05) and internal consistency (Cronbach's α = 0.702) as well as the validity (Kaiser-Meyer-Olkin, KMO = 0.731). The higher the individual score, the more likely to be BPPV (B = 2.082; P < 0.05). The mean score of answers was greater in the group with a clinical diagnosis of BPPV compared to those without BPPV (F = 58.459, P < 0.05). The sensitivity of the screening tool was 92.8% and specificity was 88.5%, with an area under the ROC curve of 0.946 (95% confidence interval 0.926-0.965; P < 0.05). CONCLUSION The questionnaire proved to be of great value to screen for individuals with possible BPPV.

Abstract
ObjectiveA low serum 25-hydroxyvitamin D (25(OH)D) level is relevant to both the occurrence and recurrence of benign paroxysmal positional vertigo (BPPV). However, whether it also contributes to residual dizziness (RD) after successful repositioning maneuvers is unknown. Therefore, this study aimed to explore the correlation between the serum 25(OH)D level and short-term RD severity in patients with BPPV after successful repositioning maneuvers.MethodsIn total, 251 patients with BPPV after successful repositioning were enrolled and prospectively followed up for 1 week (W1). Serum 25(OH)D values were detected by chemiluminescence immunoassay at enrollment (W0). In addition, we explored the relationship between 25(OH)D values at baseline and RD severity at W1 in different subgroups stratified by sex and onset age (early-onset, ≤50 years; late-onset, >50 years).ResultsThe serum 25(OH)D level of female patients was significantly lower than that of male patients (15.9 ± 6.8 vs. 19.8 ± 6.6 ng/ml, p < 0.001). Its level also decreased in early-onset patients compared to late-onset ones (15.3 ± 5.9 vs. 18.0 ± 7.3 ng/ml, p = 0.003). In addition, early-onset female patients had lower 25(OH)D values than late-onset female patients (14.0 ± 5.5 vs. 17.1 ± 7.2 ng/ml, p = 0.004). However, this difference was not observed between early- and late-onset male patients. Among early-onset female patients, the 25(OH)D values of the moderate-to-severe RD group were lower than those of the minor or no RD group (10.9 ± 3.3 vs. 14.7 ± 5.7 vs. 15.0 ± 5.9 ng/ml, p = 0.046). Multivariate analysis found that decreased 25(OH)D values were related to the occurrence of moderate-to-severe RD in early-onset female patients (OR = 0.801; p = 0.022). This effect did not exist in late-onset female or male patients with BPPV.ConclusionsAge and sex differences in serum 25(OH)D levels exist in patients with BPPV. A decreased 25(OH)D level in early-onset female patients may increase the odds of moderate-to-severe RD 1 week after successful repositioning maneuvers.

[PMID: 36648931 PMCID: PMC10011937 DOI: 10.1001/jamaneurol.2022.4944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 11/07/2022] [Indexed: 01/18/2023]
Abstract
Importance Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo with frequent recurrences. Objective To determine the efficacy of a web-based diagnosis and treatment of BPPV when it recurs in patients with confirmed and treated BPPV. Design, Setting, and Participants This randomized, controlled, parallel-group, double-blind trial took place in multiple referral-based university hospitals in South Korea between July 2017 and February 2020. Of 728 patients (age ≥20 years) with diagnosed and treated BPPV, 585 were enrolled after excluding 143 who declined participation, could not use the internet, or had spinal problems, multicanal BPPV, or cognitive dysfunction. Patients were followed up for recurrence at least for 2 years until February 2022. Interventions Patients were randomly assigned (1:1) to the treatment or control group. The patients in the treatment group completed a questionnaire for diagnosis and received a video clip for self-administration of canalith repositioning maneuver (CRM) according to the type of BPPV diagnosed when they experienced positional vertigo again. Patients in the control group received a video clip for self-administration of CRM according to the type of BPPV that had been diagnosed on enrollment. Main Outcomes and Measures The primary outcome was self-reported resolution of positional vertigo post-CRM. Secondary outcomes included difficulties and requirement for assistance when using the program and any falls or other adverse events related to CRM. The primary outcome was analyzed using both intention-to-treat and per-protocol methods. Results Of 585 patients enrolled, 292 were randomized to the treatment group (mean [SD] age, 60.3 [12.8] years, 37 [64%] women) and 293 were randomized to the control group (mean [SD] age, 61.1 [13.2] years; 50 [71%] women). Overall, 128 (21.9%) had recurrence (58 in the treatment group and 70 in the control group), and 109 (85.2%) successfully used the web-based system. In the intention-to-treat analysis, 42 of 58 individuals (72.4%) in the treatment group and 30 of 70 individuals (42.9%) in the control group reported vertigo resolution (χ2 test: 95% CI, 0.13-0.46; P < .001). Conclusions and Relevance This trial proved the efficacy of a web-based system for the diagnosis and treatment of recurrent BPPV. Use of this system may play an important role in telemedicine for vestibular disorders. Trial Registration Clinical Research Information Service Identifier: KCT0002364.

Auris Nasus Larynx 2023; 50:70-80. [PMID: 35659787 DOI: 10.1016/j.anl.2022.05.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 05/17/2022] [Accepted: 05/19/2022] [Indexed: 01/28/2023]
Abstract
OBJECTIVE To examine the relationship of 25hydroxyvitamin D serum levels with BPPV incidence and recurrence rates. METHODS A retrospective cross-sectional, case-controlled study with follow-up phone survey was performed on patients diagnosed with BPPV between 05/2017-05/2020, who had available 25hydroxyvitamin D serology. Patients were seen at a multidisciplinary, vestibular-focused, neurotology clinic at a tertiary referral center. Controls consisted of subjects from the National Health and Nutrition Examination Survey (NHANES), and a locoregional age, sex, and race-matched group of patients from our institution. RESULTS Our BPPV cohort consisted of 173 patients (mean age 66.2 ± 11.8 years), who were predominately female (75.7%) and Caucasian (76.3%). Almost all age subgroups (BPPV, NHANES, and locoregional groups) ≤60 years old had insufficient levels of vitamin D. However, the overall BPPV cohort had a significantly higher vitamin D level than the NHANES control (31.4 ± 16.5 v. 26.0 ± 11.2 ng/mL, d=0.474 [0.323, 0.626]). There was no significant difference when compared to the overall locoregional control (31.4 ± 20.5 ng/mL). Migraines were significantly correlated to increased BPPV recurrence rates on univariate (beta=0.927, p=0.037, 95% CI: [0.057, 1.798]) and multiple regression analyses (beta=0.231, 95% CI: [0.024, 2.029], p=0.045). Furthermore, patients with BPPV recurrences had significantly lower levels of vitamin D at initial presentation when compared to patients with no recurrences (29.0 ± 12.0 v. 37.6 ± 18.3 ng/mL, d=0.571[0.139,1.001]). CONCLUSION Many BPPV patients in our cohort had insufficient vitamin D levels, and patients with BPPV recurrences had insufficient and significantly lower vitamin D levels than those without. As a readily available and affordable supplement, vitamin D may be used as an adjunct treatment but prospective studies should be done to confirm if it can prevent or reduce recurrence.

Correlation between serum vitamin D level and benign paroxysmal positional vertigo recurrence. Auris Nasus Larynx 2023:S0385-8146(23)00021-4. [PMID: 36697291 DOI: 10.1016/j.anl.2022.12.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 12/03/2022] [Accepted: 12/30/2022] [Indexed: 01/25/2023]
Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) is the most common cause of dizziness in the general population. BPPV is known to be closely related to the serum vitamin D level. This study aimed to examine the relationship between serum vitamin D levels and BPPV recurrence. METHODS A retrospective chart review was conducted on 50 patients diagnosed with posterior and lateral canal BPPV. The diagnosis of BPPV was based on the finding of vertigo and nystagmus induced by certain head positions (The Dix-Hallpike maneuver and head roll tests). The patients were classified into BPPV recurrence (Group A) and non-recurrence groups (Group B). Otolith function was assessed by cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential (oVEMP), and their association with vitamin D levels was evaluated. RESULTS There were 19 subjects in Group A and 31 in Group B. There were no significant differences in age, sex, cVEMP, and oVEMP between the two groups. The average vitamin D level was 12.9 ± 8.0 ng/mL for Group A and 19.2 ± 8.2 ng/mL for Group B, and the difference between the groups was significant (p = 0.011). In the receiver operating characteristic curve analysis for BPPV recurrence with the best sensitivity and specificity, the optimal cut-off value of total serum vitamin D was determined as 12.74 ng/mL. Furthermore, reclassifying the patients based on the cut-off value showed a significantly higher recurrence rate in the group with a lower serum vitamin D level (70.5% vs. 22.5%, p = 0.007). CONCLUSION This complex finding highlights the importance of measuring serum vitamin D levels to monitor and evaluate patients at risk of BPPV recurrence.

Abstract
Background Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular vertigo. Although BPPV is benign, its underlying mechanisms are complicated, and patients diagnosed with BPPV are significantly affected by it in their daily lives. Hence, this study's purpose was to investigate global trends and frontiers in the field of BPPV. Methods We searched the research literature published from 2002 to 2021 on BPPV using two databases from the Web of Science Core Collection, and we conducted a bibliometric and visualization analysis. Bibliometric tools were used to perform co-authorship, co-citation, and co-occurrence analyses of countries or regions, institutions, authors, journals, keywords, and references. Results In all, 1,419 publications from 4,594 authors, 1,542 institutions, and 65 countries or regions with 71 subject categories were included in the study. The number of articles increased gradually from 2002 to 2021. Seoul National University, the University of Munich, and Osaka University were among the leading institutions with the most publications, while United States of America, South Korea, and China were the leading countries. JS Kim was the most prolific author, Otology & Neurotology was the most prolific journal, and Otorhinolaryngology was the most published subject category. The five most frequently occurring keywords were BPPV, vertigo, dizziness, nystagmus, and management and the top research hot spots were osteoporosis and vitamin D. Conclusion This study systematically analyzed trends in global scientific research on BPPV. The academic understanding of BPPV has improved significantly over the last two decades, with osteoporosis and vitamin D the two main research hot spots in the field of BPPV in recent years. These findings provide direction for current research to grasp the trends and research frontiers of current research.

Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) is commonly attributed to displaced otoconia. These have been shown to have biomineralization close to that of bone, and vitamin D deficiency has been associated with BPPV. We aim to systematically review the available literature on vitamin D supplementation and BPPV intensity and recurrence in adults. DATABASES REVIEWED PubMed, MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Current Controlled Trials, and ClinicalTrials.gov. METHODS We systematically reviewed the available literature from 1947 to April 2020. The study protocol was registered in the PROSPERO database (trial registration: CRD42020183195). RESULTS A total of 179 abstracts were identified and screened by two independent reviewers. Based on inclusion and exclusion criteria, six studies were selected and subjected to a quality assessment. In one randomized clinical trial (RCT), vitamin D supplementation was found to reduce annual recurrence rate of vertigo in patient with BPPV and subnormal serum vitamin D levels compared with placebo (odds ratio, 0.69; 95% confidence interval, 0.54-0.90). Non-RCTs demonstrated the possibility of a null effect in the random effects model (odds ratio, 0.08; 95% confidence interval, 0.00-1.56). The RCT considered as low risk of bias. All of the nonrandomized studies were assessed as serious risk of bias. CONCLUSIONS The intervention studies identified consistently demonstrated a decrease in BPPV recurrence with supplementation of vitamin D in patients with subnormal vitamin D levels. Although there is a paucity of high-quality studies, the present literature does highlight a role for optimization of vitamin D levels in patients with BPPV.

Abstract
Introduction Benign paroxysmal positional vertigo (BPPV) is a type of vertigo and its signs are short-time, severe attacks that occur in certain head and body positions. Recent studies have revealed that vitamin D deficiency correlates with BPPV and this is explained by cupulolithiasis and canalithiasis theories. Method In the present study, levels of serum vitamin D in the patients who were diagnosed as BPPV and those in the control group consisting of healthy individuals were investigated. In addition, it was examined whether vitamin D is influential on the rates of BPPV types. In our study, 258 patients who were diagnosed with BPPV after detailed ear-nose-throat and neurology examinations were examined. We compared the control group according to their ages, genders, and levels of vitamin D. In addition, we divided the BPPV group into two sub-groups according to their vitamin D levels (20-30 ng/ml and 20 g/ml lower), and each was compared by calculating vertigo types and ratios. Results The BPPV group included 187 females and 71 males, and their mean age was 43.70 ± 15.44. The control group consisted of 65 females and 35 males, and the mean age of this group was 44.63 ± 15.42. The mean vitamin D levels of the females and males were 18.42 ± 5.07 and 19.82 ± 5.11, respectively, in this study. On the other hand, the mean vitamin D levels of healthy females and males were found to be 30.88 ± 10.74. Conclusion Our study found that the vitamin D levels of the individuals in the BPPV group were statistically significantly lower than those of the individuals who were in the control group. However, it was observed that vitamin D did not affect the rate of vertigo subtypes.

Abstract
Abstract
Introduction Benign paroxysmal positional vertigo (BPPV) appears during the same age group in which vitamin D and calcium deficiencies are evident. Vitamin D deficiency could predispose to BPPV, since these two entities share a demineralization process.
Objective To establish the otological impact of vitamin D supplementation in patients with its deficiency who suffer from BPPV.
Methods This was a randomized clinical trial. A total of 35 patients with vitamin D deficiency (< 30 ng/ml) and BPPV were divided into 2 groups: Group 1 (control group): treatment with repositioning maneuvers; and Group 2: treatment with repositioning maneuvers and vitamin D supplementation.
Results A follow-up of between 6 and 13 months and a log rank test revealed that the probability of recurrence between the experimental groups was significantly different, with group 2 having a decreased recurrence of vertigo (p = 0.17). Scores in the Dizziness Handicap inventory (DHI) in patients treated with vitamin D supplementation were smaller (10 ± 9) when compared with a score of 36 ± 9 in the control group.
Conclusion Plasmatic values of 25-hydroxyvitamin D have an impact in patients with BPPV, who present an improvement in their quality of life when their vitamin D levels are replaced with supplementation. Benign paroxysmal positional vertigo could stop being perceived as a purely otologic disease.

Abstract
Introduction
Benign paroxysmal positional vertigo (BPPV) is one of the common disorders of the peripheral vestibular system. The prevalence of BPPV is found to be higher among middle-aged women.
Objectives
To estimate the serum levels of calcium and vitamin D in patients with BPPV, and to study their association.
Methods
The present is a hospital-based prospective case-control study. Venous blood samples of the 49 patients with BPPV and an equal number of age- and gender-matched individuals were recruited and submitted to an analysis of the serum levels of calcium and vitamin D.
Results
Among the cases, 67.3% were found to be females, and 32.7% were males. Most of the 30 cases (61.3%) were aged > 40 years. The mean age of the cases was 44.39 years. The mean serum level of vitamin D in the cases was of 21.26 ng/ml compared with 17.59 ng/ml in the controls. The mean serum level of calcium was of 9.33 mg/dl in the cases, compared with 8.95 mg/dl in the controls. There was no significant difference in the serum levels of vitamin D and calcium between cases and controls.
Conclusion
We could not establish any correlation between the serum levels of calcium and vitamin D with BPPV. However, a negative relationship was found between the serum levels of vitamin D and the number of episodes of BPPV (
p
= 0.012).

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.

Risk Factors for Recurrence of Benign Paroxysmal Positional Vertigo. A Clinical Review. J Clin Med 2021; 10:jcm10194372. [PMID: 34640391 PMCID: PMC8509726 DOI: 10.3390/jcm10194372] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 09/17/2021] [Accepted: 09/23/2021] [Indexed: 12/04/2022] Open
Abstract
Benign paroxysmal positional vertigo (BPPV) is one of the most common peripheral vestibular dysfunctions encountered in clinical practice. Although the treatment of BPPV is relatively successful, many patients develop recurrence after treatment. Our purpose is to evaluate the mean recurrence rate and risk factors of BPPV after treatment. A review of the literature on the risk factors of BPPV recurrence was performed. A thorough search was conducted using electronic databases, namely Pubmed, CINAHL, Academic Search Complete and Scopus for studies published from 2000 to 2020. Thirty studies were included in this review with 13,358 participants. The recurrence rate of BPPV ranged from 13.7% to 48% for studies with follow-up <1 year, and from 13.3% to 65% for studies with follow-up ≥2 years. Pathophysiologic mechanisms and implication of each of the following risk factors in the recurrence of BPPV were described: advanced age, female gender, Meniere’s disease, trauma, osteopenia or osteoporosis, vitamin D deficiency, diabetes mellitus, hypertension, hyperlipidemia, cardiovascular disease, migraine, bilateral/multicanal BPPV, cervical osteoarthrosis and sleep disorders. Patients with hyperlipidemia and hypertension had the highest recurrence rates of BPPV, 67.80% and 55.89%, respectively, indicating that vascular comorbidities increase the risk of BPPV recurrence. In addition, more than half of patients (53.48%) with diabetes mellitus and BPPV experienced recurrence of BPPV. Knowledge and awareness of risk factors for recurrence of BPPV are essential for the assessment and long-term prognosis of patients. Identification of these relapse risk factors may enhance the ability of clinicians to accurately counsel patients regarding BPPV and associated comorbidities.

Abstract
Benign paroxysmal positional vertigo (BPPV) is the most common cause of positional vertigo. Vitamin D deficiency may be one of the causes of its development. To assess the relation between recurrent attacks BPPV and Vitamin D deficiency. A case control study in which 40 patients were clinically diagnosed as posterior canal BPPV, Serum 25(OH) D was measured at 1st visit. Patients were divided into two groups; group A (20 patients) received Vitamin D supplementation in addition to canal repositioning maneuver and group B (20 patients) treated by canal repositioning maneuver only. Follow up of all patients for 6 months, neuro-otological assessment was repeated and recurrent attacks were recorded. Serum vitamin D was repeated after 6 month. This study included 14 males and 26 females age ranged from 35 to 61 years, Average serum of 25 (OH) D at the first visit was (12.4 ± 2 ng/ml) for group A, and (12.2 ± 1.7 ng/ml) for group B, all patients had low serum level of 25(OH) D (below 20 ng/ml). Recurrent BPPV episodes, were significantly lower in group A than that of group B. There is a relation between BPPV recurrence and low serum Vitamin D.

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
Benign paroxysmal positional vertigo is characterized by recurrence, which exposes patients to repeated vertigo attacks. Vitamin D deficiency has been found to be a risk factor in benign paroxysmal positional vertigo, although effect of its elimination on recurrence reduction remains unknown. To determine the effect of vitamin D supplementation in preventing recurrence of benign paroxysmal positional vertigo patients with vitamin D deficiency using a meta-analysis study. We searched and retrieved relevant articles from several databases, then used the Cochrane evaluation system or Methodological Index for Non-Randomized Studies (MINORS) to assess the quality of studies. We adopted risk-ratio (RR) with corresponding 95% confidence interval (CI) to determine effect sizes, and further performed statistical analyses under a randomized- or fixed-effects model. Seven studies, comprising 602 and 731 participants in the case and control group respectively, met our inclusion criteria, and were therefore included in the meta-analysis. Assessment based on Cochrane evaluation system or MINORS revealed that most of the studies had high quality. Moreover, the randomized- model revealed that the vitamin D supplementation group had a lower recurrence rate than the control group which did not accepted vitamin D supplementation (RR = 0.41, 95% CI = 0.26-0.65, p < 0.01). Overall, these findings indicate that vitamin D supplementation can significantly lower recurrence in benign paroxysmal positional vertigo and vitamin D deficiency.

Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) is characterized by recurrent attacks of vertigo caused by head movements. It occurs as a result of otoconia falling into the semicircular canal. Calcium and 25 hydroxyvitamin D [25(OH)D] metabolism in the inner ear play an important role in otoconia formation and degeneration. Our aim in this study was to investigate the relationship between 25(OH)D levels and BPPV. METHODS This retrospective, case-controlled study included 52 patients with posterior canal BPPV and 52 controls aged 18 to 80 years. Age, sex, serum calcium, corrected calcium, and 25(OH)D levels of the BPPV and control group were compared. RESULTS Twenty-three of the patients were male (44.2%) and 29 were female (55.8%). The average age was 55.6 years. The 25(OH)D level was 15.3 ng/mL in the BPPV group and 20.2 ng/mL in controls. There was no significant difference in 25(OH)D and albumin-corrected calcium values (P = .394; P = .084, respectively). In 80.7% of the BPPV group and 61.5% of the controls, 25(OH)D levels were 20 ng/mL and below. 25 hydroxyvitamin D deficiency was found statistically significantly more frequently in patients with BPPV (P = .030). CONCLUSION In our study, serum 25(OH)D levels were found to be lower in patients with BPPV, and the rate of vitamin D deficiency was higher in these patients. Based on these results, it is recommended to examine the 25(OH)D levels of patients with BPPV at the time of diagnosis.

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
Benign paroxysmal positional vertigo (BPPV) is one of the most common vestibular disorders. An investigation into the factors related to BPPV could contribute to its prevention and appropriate management. We investigated the association between climatic factors and incidence of BPPV in this study. A total of 365 patients who were diagnosed with idiopathic BPPV in the emergency room of our hospital in 2015 were included. The number of patients diagnosed with BPPV per week was calculated (every week). Climatic factors, including daily average humidity, temperature, atmospheric pressure, cloud amount, sunshine amount, and daylight time, were documented daily. The weekly mean climatic value in each week was calculated. Simple correlation analysis and multivariate regression analyses were performed to identify climatic factors associated with the number of patients diagnosed with BPPV. Simple correlation analysis revealed a significant association between the humidity (r = 0.276, p = 0.048), temperature (r = 0.275, p = 0.049), and cloud amount (r = 0.293, p = 0.035) and the number of BPPV patients diagnosed per week. Multivariate regression analysis revealed that only the cloud amount was a statistically significant factor associated with the number of BPPV patients diagnosed every week. A significant positive association was discovered between the cloud amount and BPPV incidence. Cloud amount can therefore have an association with the incidence of BPPV.

Abstract
Many investigations have found common occurrences of benign paroxysmal positional vertigo (BPPV) in women, and clinical experience has shown that BPPV can develop due to increased hormonal fluctuations, especially during menopause. Therefore, knowledge about neurochemicals and their involvement with BPPV is imperative for the management of neurological issues in women. This review will discuss appropriate gender-based considerations of BPPV based on experimental and clinical evidence. The studies describe 2 lines of evidence regarding the association of perimenopause in women and the development of BPPV: (1) experimental evidence: the existence of estrogen receptors in the inner ear, otoconial malformations in osteopenic/osteoporotic rats, changes in otoconin 90 caused by hormone replacement therapy, and impaired calcium absorption following estrogen deprivation corrected by estrogen replacement therapy and (2) clinical evidence: epidemiological aspects, osteoporosis and estrogen deficiency. Future studies are necessary to validate the effects of hormonal replacement therapy and phytoestrogen in women with recurrent BPPV.

Abstract
Background Benign paroxysmal positional vertigo (BPPV) is a common, self‐limited, and favorable prognostic peripheral vestibular disorder. BPPV is transmitted in an autosomal dominant fashion, but most cases occur sporadically. Little research has been reported regarding the mutation spectrum of sporadic BPPV in a large cohort. This study attempted to identify the causative candidate variants associated with BPPV in VDR, LOXL1, and LOXL1‐AS1. Methods An amplicon‐targeted next‐generation sequencing (NGS) method for VDR, LOXL1, and LOXL1‐AS1, was completed in 726 BPPV patients and 502 normal controls. A total of 30 variants (20 variants from VDR, nine variants from LOXL1, seven variants from LOXL1‐AS1) were identified in these two groups. Results Three of 30 variants were nonsynonymous mutations, but no significant difference was found between the BPPV group and the control group via association analysis. A single nucleotide variant (SNV), rs1078967, was identified that is located in intron 1 of LOXL1. The allelic frequency distribution differed significantly between the BPPV group and the control group (p = 0.002). Genotypic frequency was also significantly different (p = 0.006), as determined by gene‐based analyses. Conclusion This report is the first to analyze the variant spectrum of BPPV in a large Chinese population.

Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) has a high recurrence rate, but the risk factor-associated recurrence are elusive. METHODS Searches were performed in PubMed, Embase, Cochrane library, Web of science, Chinese National Knowledge Infrastructure, and Sino Med up to November 3, 2019. The effect size was analyzed by odds ratio and 95% CI. Data from eligible studies were meta-analyzed using Stata version 15.0. RESULTS Our search resulted in a total of 4076 hits. Twenty-four outcomes of sixty articles were included in the meta-analysis. Risk factors for the recurrence of BPPV included female gender, age (≥65years), hyperlipidemia, diabetes, hypertension, migraine, cervical spondylosis, osteopenia/osteoporosis, head trauma, otitis media, abnormal vestibular evoked myogenic potential, and long use of computers. No significant differences were found in side, type of the involved semicircular canals, smoking, alcohol consumption, stroke, ear surgery, duration of vertigo before treatment, the times of repositioning, Meniere disease, sleep disorders, hypercholesterolemia, and 25-hydroxy vitamin D. CONCLUSION These findings strengthen clinical awareness of early warning to identify patients with potential relapse risk of BPPV and clinicians should counsel patients regarding the importance of follow-up after diagnosis of BPPV.

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
The genesis of the Benign Paroxysmal Positional Vertigo (BPPV) seems to be related to some metabolic factors. These factors, such as vitamin D, glucocorticoids, and even thyroid and growth hormones, can affect bone metabolism and the mineralization of otoconia. It also seems to link to factors related to aging or nutritional habits. Besides, since the incidence of BPPV is quantitatively higher in women than in men, female sex steroids could be associated with this process. It could be useful to understand how these factors act in otoconial mineralization if we want to develop treatments aimed at preventing or delaying BPPV recurrences. In this review, we will analyze the role of these metabolic and hormonal factors in otoconial mineralization and in the treatment of BPPV.

Abstract
OBJECTIVE In this review the authors discuss evidence from the literature concerning vitamin D and temporal bone diseases (benign paroxysmal positional vertigo [BPPV], Menière's disease [MD], vestibular neuritis, idiopathic facial paralysis, idiopathic acute hearing loss). Common features shared by Menière's disease, glaucoma, and the possible influence by vitamin D are briefly discussed. DATA SOURCES, STUDY SELECTION Publications from 1970 until recent times have been reviewed according to a keyword search (see above) in PubMed. CONCLUSIONS MD, BPPV, vestibular neuritis, idiopathic facial paralysis, idiopathic acute hearing loss may all have several etiological factors, but a common feature of the current theories is that an initial viral infection and a subsequent autoimmune/autoinflammatory reaction might be involved. Additionally, in some of these entities varying degrees of demyelination have been documented. Given the immunomodulatory effect of vitamin D, we postulate that it may play a role in suppressing an eventual postviral autoimmune reaction. This beneficial effect may be enhanced by the antioxidative activity of vitamin D and its potential in stabilizing endothelial cells. The association of vitamin D deficiency with demyelination has already been established in other entities such as multiple sclerosis and experimental autoimmune encephalitis. Mice without vitamin D receptor show degenerative features in inner ear ganglia, hair cells, as well as otoconia. The authors suggest further studies concerning the role of vitamin D deficiency in diseases of the temporal bone. Additionally, the possible presence and degree of demyelination in these entities will have to be elucidated more systematically in the future.

Abstract
Introduction
There have been reports indicating that patients with frequently recurring benign paroxysmal positional vertigo (BPPV) had vitamin D deficiency, and some studies indicated that the treatment of severe vitamin D deficiency is effective in the reduction of the recurrence of BPPV.
Objective
The purpose of the present study was to examine the effects of Vitamin D
3
injection on recurrence among patients with a 10 ng/mL or lower 25-hydroxyvitamin D blood concentration diagnosed with BPPV.
Methods
Among 99 patients with idiopathic BPPV with vitamin D deficiency, 25 patients (case group) were submitted to 3 to 4 injections of 200,000 IU of vitamin D
3
in the first year. In total, 50 patients in the control group were selected through frequency matching, with 25 patients in the case group. Age, gender, and type of BPPV are used in matching variables with 1:2 matched data. The subjects of the study group were followed up for 24 months.
Results
The differences in relapse rates between the case and the control groups were examined using the non-parametric Kruskal-Wallis test for k independent samples. With regard to the relapse rates of the entire case and control groups by period, from 0 to 6 months (
p
< 0.531), from 7 to 12 months (
p
< 1.000), and from 13 to 24 months (
p
< 0.711), and in the entire study period (
p
< 0.883) there were no statistically significant differences.
Conclusion
The present case-control study indicated that vitamin D
3
injection had no significant effect on the recurrence of BPPV patients with vitamin D deficiency when age, gender, and type of BPPV were homogeneous between the two groups.

Abstract
Vitamin D is very important for children's health. Previous studies have shown that vitamin D deficiency leads to a series of diseases in adults. However, pediatricians are mostly aware of rickets caused by vitamin D deficiency in children and poorly aware of other symptoms. This study aimed to retrospectively analyze the different clinical features of vitamin D deficiency to enhance identification by pediatricians, thus minimizing misdiagnosis. In this study, we retrospectively analyzed the clinical features of vitamin D deficiency in 268 children aged 0-14 years from June 2016 to May 2018 in the Third Affiliated Hospital of Zhengzhou University. Serum 25-hydroxy vitamin D [25(OH)D] levels were determined using the chemiluminescence method. Of the 268 cases, 101 cases showed movement disorder (37.7%) and 167 nervous system abnormalities (62.3%). Among all cases, 6 were misdiagnosed as febrile seizures (2.23%), 5 as epilepsy (1.86%), 2 as Tourette syndrome (0.74%), and 2 as developmental retardation (0.74%). There were significant differences in patients with clinical characteristics of movement disorder and nervous system abnormalities partly between Pre-and post-vitamin D treatment. This analysis revealed that vitamin D deficiency occurs not only in children but also in adolescents, with diverse clinical features. Therefore, pediatricians should pay more attention to clinical different signs and symptoms, and future studies should be conducted to confirm the mechanisms of these processes.

Abstract
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of systemic vertigo in clinical practice. The results of recent research demonstrated the decrease of bone mineral density, level of vitamin D and estrogen in blood serum in patients with BPPV. In summary these data points at the relationship between osteoporosis/osteopenia and BPPV. This association is most obvious in menopausal women and in those with recurrent BPPV. Patients with recurrent BPPV should undergo investigation for osteoporosis/osteopenia. Treatment of bone-mineral metabolism allows decreasing the frequency of BPPV recurrence, however more research is needed in this area.

Abstract
The pathophysiological mechanism underlying benign paroxysmal positional vertigo (BPPV) is related to free-floating debris/otoliths in the semicircular canal (canalolithiasis) or debris/otoliths attached to the cupula (cupulolithiasis). These debris/otoliths are considered to originally accumulate after detachment from the neuroepithelium of the utricular macula secondary to a type of degeneration. An idiopathic form, which is assumed to occur spontaneously, is diagnosed when the causative pathology is obscure. However, an association between various other systemic or inner ear conditions and BPPV has been reported, indicating the existence of secondary BPPV. This study was performed to present the first review of the pathology underlying BPPV following a complete PubMed/Medline search. In total, 1932 articles published from 1975 to 2018 were reviewed. The articles were classified according to 17 potentially causative factors (aging; migraine; Meniere's disease; infection; trauma; idiopathic sudden sensorineural hearing loss; sleeping habits; osteoporosis and vitamin D insufficiency; hyperglycemia and diabetes mellitus; chronic head and neck pain; vestibule or semicircular canal pathology; pigmentation disorders; estrogen deficiency; neurological disorders; autoimmune, inflammatory, or rheumatologic disorders; familial or genetic predisposition; and allergy). A discussion of the underlying cause of BPPV for each factor is presented.

Abstract
OBJECTIVE Low vitamin D levels have been associated with and could play a role in the pathogenesis of idiopathic benign paroxysmal positional vertigo (iBPPV). Since otoconia degeneration contributes to iBPPV and a lack of vitamin D may impact otoconia structure and integrity, we proposed a negative association between vitamin D levels and levels of a proposed circulatory biomarker for otolithic degeneration, otolin-1. STUDY DESIGN Cross-sectional clinical study. SETTING Clinical research center. PATIENTS Seventy-nine men and women ranging in age from 22 to 95 years old without known vertigo. INTERVENTIONS Diagnostic. MAIN OUTCOME MEASURES Blood levels of 25-OH vitamin D and otolin-1. RESULTS Previously, we had reported higher otolin-1 levels in older age groups. The majority of the subjects (83%) had vitamin D levels that were below 40 ng/ml. Vitamin D level was lowest in the young and increased with age before declining in subjects 70 years of age and older (p = 0.005). There was a negative correlation between vitamin D and otolin-1 levels of subjects over 70 (r = -0.36, p = 0.036). CONCLUSION Our results demonstrate a relationship between vitamin D and otolin-1. The majority of our subjects had abnormally low vitamin D levels, but only those over 70 years of age showed a negative correlation with high otolin-1 levels. We postulate that a seasonal drop in vitamin D may not be sufficient for otoconia fragmentation and ultimately iBPPV, rather, chronically low vitamin D maybe required to induce otoconia degeneration.

Abstract
OBJECTIVE Benign paroxysmal positional vertigo (BPPV) was the most common neuro-otological disorder manifests as recurrent positional vertigo, but its risk factors are elusive. Recent studies suggest that decreased Vitamin D level may be a risk factor, but the literature is inconsistent. METHODS The databases PubMed, Web of Science, Chinese National Knowledge Infrastructure, Wanfang, SinoMed, and Embase were systematically searched for studies on the association between BPPV and serum Vitamin D levels published up to June 2019. Data from eligible studies were meta-analyzed using Stata 12.0. RESULTS A total of 18 studies were included in the analysis. Serum Vitamin D levels were significantly lower in individuals with BPPV than in controls (WMD - 2.46, 95% CI - 3.79 to - 1.12, p < 0.001). Subgroup analysis by geographical area showed that vitamin D level was significantly lower in BPPV than in controls in China (WMD - 3.27, 95% CI - 4.12 to - 2.43, p < 0.001), but not outside China (WMD - 0.90, 95% CI - 4.36 to 2.56, p = 0.611). Vitamin D levels were significantly lower in recurrent than non-recurrent BPPV across all countries in the sample (WMD 2.59, 95% CI 0.35-4.82, p = 0.023). Vitamin D deficiency emerged as an independent risk factor of BPPV (OR 1.998, 95% CI 1.400-2.851, p < 0.001). CONCLUSION The available evidence suggests that BPPV is associated with decreased levels of serum Vitamin D, and vitamin D deficiency was an independent risk factor for BPPV.

Abstract
PURPOSE To assess the correlation between the comorbidities, such as hypertension, diabetes, thyroid disorders, hearing loss, hyperlipidemia, and vitamin D deficiency and benign paroxysmal positional vertigo (BPPV) and to determine the high-risk groups for recurrence of symptoms. DESIGN Descriptive analytical study. MATERIALS AND METHODS Patients who met the inclusion criteria underwent complete ear, nose, and throat examination, including Dix-Hallpike test and roll-over test and blood pressure recording. Investigations included pure tone audiometry, random blood sugar/fasting blood sugar, serum thyroid-stimulating hormone, fasting serum total cholesterol, and serum vitamin D levels. Patients were followed up for a period of 6 months to 1 year. RESULTS Older age-group has an increased risk of BPPV and recurrence of symptoms. About 45.1% of the patients with BPPV who were detected to have symptoms of hypertension were also more common with hypertensive. Diabetes mellitus was found to have an increased risk of BPPV and its recurrence. The presence of other comorbidities, such as abnormal thyroid function test (9%), sensorineural hearing loss (14%), hypercholesterolemia (46%), and vitamin D deficiency (79%) didn't show any significant risk for recurrence. CONCLUSION The presence of comorbidities worsens the status of BPPV, causing more frequent otolith detachment. Hence, it increases the risk of recurrence even after successful repositioning maneuver. Patients presenting with BPPV should therefore be evaluated and treated for these comorbidities along with the repositioning maneuvers.

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.
