Abstract
Chronic fatigue syndrome (CFS), fibromyalgia (FM), silicone breast implants (SBI), Coronavirus-19 infectious disease (COVID), COVID-19 vaccination (post-COVIDvac-syndrome), Long-COVID syndrome (PCS), sick-building syndrome (SBS), post-orthostatic tachycardia syndrome (PoTS), and autoimmune/ inflammatory syndrome induced by adjuvants (ASIA) are a cluster of poorly understood medical conditions that have in common a group of ill-defined symptoms and dysautonomic features. Most of the clinical findings of this group of diseases are unspecific, such as fatigue, diffuse pain, cognitive impairment, paresthesia, tachycardia, anxiety, and depression. Hearing disturbances and vertigo have also been described in this context, the underlying pathophysiologic process for these conditions might rely on autonomic autoimmune dysbalance. The authors procced a literature review regarding to hearing and labyrinthic disturbances in CSF, FM, SBI, COVID, post-COVIDvac-syndrome, PCS, SBS, POTS, and ASIA. The PRISMA guidelines were followed, and the literature reviewed encompassed papers from January 1990 to January 2024. After the initial evaluation of the articles found in the search through Pubmed, Scielo and Embase, a total of 172 articles were read and included in this review. The prevalence of hearing loss, dizziness, vertigo and tinnitus was described and correlated with the diseases investigated in this study. There are great variability in the frequencies of symptoms found, but cochlear complaints are the most frequent in most studies. Vestibular symptoms are less reported. The main pathophysiological mechanisms are discussed. Direct effects of the virus in the inner ear or nervous pathways, impaired vascular perfusion, cross-reaction or autoimmune immunoreactivity, oxidative stress, DNA methylation, epigenetic modifications and gene activation were implicated in the generation of the investigated symptoms. In clinical practice, all patients with these autoimmune conditions who have any audiological complaint an ENT consultation followed by an audiometry are needed.

Abstract
Introduction Conductive hearing loss (CHL) attenuates the ability to transmit air conducted sounds to the ear. In humans, severe hearing loss is often accompanied by alterations to other neural systems, such as the vestibular system; however, the inter-relations are not well understood. The overall goal of this study was to assess vestibular-related functioning proxies in a rat CHL model. Methods Male Sprague-Dawley rats (N=134, 250g, 2months old) were used in a CHL model which produced a >20dB threshold shift induced by tympanic membrane puncture. Auditory brainstem response (ABRs) recordings were used to determine threshold depth at different times before and after CHL. ABR threshold depths were assessed both manually and by an automated ABR machine learning algorithm. Vestibular-related functioning proxy assessment was performed using the rotarod, balance beam, elevator vertical motion (EVM) and Ferris-wheel rotation (FWR) assays. Results The Pre-CHL (control) threshold depth was 27.92dB±11.58dB compared to the Post-CHL threshold depth of 50.69dB±13.98dB (mean±SD) across the frequencies tested. The automated ABR machine learning algorithm determined the following threshold depths: Pre-CHL=24.3dB, Post-CHL same day=56dB, Post-CHL 7 days=41.16dB, and Post-CHL 1 month=32.5dB across the frequencies assessed (1, 2, 4, 8, 16, and 32kHz). Rotarod assessment of motor function was not significantly different between pre and post-CHL (~1week) rats for time duration (sec) or speed (RPM), albeit the former had a small effect size difference. Balance beam time to transverse was significantly longer for post-CHL rats, likely indicating a change in motor coordination. Further, failure to cross was only noted for CHL rats. The defection count was significantly reduced for CHL rats compared to control rats following FWR, but not EVM. The total distance traveled during open-field examination after EVM was significantly different between control and CHL rats, but not for FWR. The EVM is associated with linear acceleration (acting in the vertical plane: up-down) stimulating the saccule, while the FWR is associated with angular acceleration (centrifugal rotation about a circular axis) stimulating both otolith organs and semicircular canals; therefore, the difference in results could reflect the specific vestibular-organ functional role. Discussion Less movement (EVM) and increase time to transverse (balance beam) may be associated with anxiety and alterations to defecation patterns (FWR) may result from autonomic disturbances due to the impact of hearing loss. In this regard, vestibulomotor deficits resulting in changes in balance and motion could be attributed to comodulation of auditory and vestibular functioning. Future studies should manipulate vestibular functioning directly in rats with CHL.

Abstract
PURPOSE To delineate the association between otolithic dysfunction and orthostatic hypotension (OH). METHODS We retrospectively reviewed the medical records of 382 patients who presented with orthostatic dizziness at a tertiary dizziness center between July 2017 and December 2021. Patients were included for analyses when they had completed ocular (oVEMP) and/or cervical vestibular-evoked myogenic potentials (cVEMP), and head-up tilt table test with a Finometer (n = 155). We compared the results between the patients with OH (n = 38) and those with NOI (normal head-up tilt table test despite orthostatic intolerance, n = 117). RESULTS Thirty-eight patients with OH were further categorized as either classic (n = 30), delayed (n = 7), or initial (n = 1) types. Multivariable logistic regression showed that OH was associated with high baseline systolic BP (p = 0.046), presence of heart failure (p = 0.016), and unilateral oVEMP abnormalities (p = 0.016). n1 latency of oVEMP were negatively correlated with the maximal changes of systolic blood pressure (BP) in 15 s ([Formula: see text]SBP15s, p = 0.013), 3 min ([Formula: see text]SBP3min, p = 0.005) and 10 min ([Formula: see text]SBP10min, p = 0.002). In contrast, the n1-p1 amplitude was positively correlated with [Formula: see text]SBP15s (p = 0.029). Meanwhile, p13 latency of cVEMP was negatively correlated with [Formula: see text]SBP10min (p = 0.018). CONCLUSIONS Our study provides evidence of utricular dysfunction related to OH.

Abstract
BACKGROUND No objective criteria exist for diagnosis and treatment of visual-vestibular mismatch (VVM). OBJECTIVE To determine whether measures of electrodermal activity (EDA) and trunk acceleration will identify VVM when exposed to visual-vestibular conflict. METHODS A modified VVM questionnaire identified the presence of VVM (+ VVM) in 13 of 23 young adults (34 ± 8 years) diagnosed with vestibular migraine. Rod and frame tests and outcome measures for dizziness and mobility were administered. Participants stood on foam while viewing two immersive virtual environments. Trunk acceleration in three planes and electrodermal activity (EDA) were assessed with wearable sensors. Linear mixed effect (LME) models were used to examine magnitude and smoothness of trunk acceleration and tonic and phasic EDA. Welch's t-test and associations between measures were assessed with a Pearson Correlation Coefficient. Effect sizes of group mean differences were calculated. RESULTS Greater than 80% of all participants were visually dependent. Outcome measures were significantly poorer in the + VVM group: tonic EDA was lower (p < 0.001) and phasic EDA higher (p < 0.001). Postural accelerations varied across groups; LME models indicated a relationship between visual context, postural, and ANS responses in the + VVM group. CONCLUSIONS Lower tonic EDA with + VVM suggests canal-otolith dysfunction. The positive association between vertical acceleration, tonic EDA, and visual dependence suggests that increased vertical segmental adjustments are used to compensate. Visual context of the spatial environment emerged as an important control variable when testing or treating VVM.

Abstract
Purpose Despite sporadic case reports describing hearing problems in patients with coronavirus disease 2019 (COVID-19), whether COVID-19 affects the audiovestibular system remains unclear. This study assessed the evolution of incidence of audiovestibular disorders during the pandemic COVID-19 period. Method Three audiovestibular disorders namely, sudden sensorineural hearing loss (SSHL), autonomic dysfunction, and Meniere’s disease (MD) were analyzed and compared from 2016 to 2020. Results The annual new cases at our clinic comprised overall 2107, 1997, 1984, 2068, and 1829 from 2016 to 2020, respectively, and the respectively annual cases of SSHL were 54, 46, 42, 45 and 38. Accordingly, annual incidences of SSHL in relation to overall cases of audiovestibular disorders were 2.6%, 2.3%, 2.1%, 2.2% and 2.1% from 2016 to 2020, respectively, exhibiting a non-significant difference (p > 0.05). In contrast, incidence of autonomic dysfunction in the year 2020 was 15.3%, which revealed significantly higher than 8.5–13.1% from 2016 to 2019 (p < 0.001). Restated, the incidence of autonomic dysfunction in 2020 displayed a significantly higher percentage than the other 4 years. Conversely, the incidence of MD in 2020 was 9.8%, showing a significant decline compared with the other 4 years (12.6–15.6% from 2016 to 2019, p < 0.001), Conclusion Evolution of incidence of audiovestibular disorders during the pandemic COVID-19 period revealed increase in the incidence of autonomic dysfunction and decrease in that of MD, while incidence of SSHL remained unchanged from 2016 to 2020. Thus, the SARS-CoV-2 may less affect the audiovestibular system.

Abstract
OBJECTIVE To evaluate whether Chronic Isolated Light-headedness (CIL) commonly manifested in elderly patients is related with cerebral oxygen insufficiency. METHODS In this case-control study, 462 patients (aged 40-83 years) with CIL and 238 clinical data matched controls were enrolled consecutively from January 2011 to September 2014. The plasma levels of "phospholipids with solubility similar to that of lysophosphatidic acid" (PSS-LPA), a surrogate marker for cerebral oxygen insufficiency, were assayed for all subjects to compare the occurrence and severity of CIL with the values of PSS-LPA. RESULTS Patients with CIL had significantly higher plasma levels of PSS-LPA than controls, regardless of having or having not psychogenic abnormalities, χ2 = 448, odds ratio (95% CI) = 140 (72-260), P < 0.001; the mean plasma levels, 0.573 vs. 0.290 mmol/L respectively (P < 0.001). Receiver operator characteristic (ROC) analyses showed plasma PSS-LPA was both sensitive and specific for CIL. The area under ROC curve (AUC) was as high as 0.953 (0.938-0.968). The changes in severity of CIL between two separate assays of one month apart were correlated closely with the changes in plasma levels of PSS-LPA for the same patients, correlation coefficient (Spearman) = 0.90, p < 0.001. CONCLUSIONS CIL is a manifestation of abnormal plasma levels of phospholipids which suggests cerebral oxygen insufficiency. This new finding shows that cerebral oxygen insufficiency is not rare especially in elderly persons.

Abstract
This paper presents the diagnostic criteria for hemodynamic orthostatic dizziness/vertigo to be included in the International Classification of Vestibular Disorders (ICVD). The aim of defining diagnostic criteria of hemodynamic orthostatic dizziness/vertigo is to help clinicians to understand the terminology related to orthostatic dizziness/vertigo and to distinguish orthostatic dizziness/vertigo due to global brain hypoperfusion from that caused by other etiologies. Diagnosis of hemodynamic orthostatic dizziness/vertigo requires: A) five or more episodes of dizziness, unsteadiness or vertigo triggered by arising or present during upright position, which subsides by sitting or lying down; B) orthostatic hypotension, postural tachycardia syndrome or syncope documented on standing or during head-up tilt test; and C) not better accounted for by another disease or disorder. Probable hemodynamic orthostatic dizziness/vertigo is defined as follows: A) five or more episodes of dizziness, unsteadiness or vertigo triggered by arising or present during upright position, which subsides by sitting or lying down; B) at least one of the following accompanying symptoms: generalized weakness/tiredness, difficulty in thinking/concentrating, blurred vision, and tachycardia/palpitations; and C) not better accounted for by another disease or disorder. These diagnostic criteria have been derived by expert consensus from an extensive review of 90 years of research on hemodynamic orthostatic dizziness/vertigo, postural hypotension or tachycardia, and autonomic dizziness. Measurements of orthostatic blood pressure and heart rate are important for the screening and documentation of orthostatic hypotension or postural tachycardia syndrome to establish the diagnosis of hemodynamic orthostatic dizziness/vertigo.

Abstract
We aim to demonstrate possible autonomic dysfunction based on salivary α-amylase measurements during and after the vertigo attacks associated with Ménière disease (MD) and benign paroxysmal positional vertigo (BPPV). Patients admitted to the emergency room with a diagnosis of vertigo attacks caused by either MD (n = 15) or BPPV (n = 9) constituted the study groups. The control group (n = 10) consisted of volunteer patients admitted to the emergency department with minor soft-tissue trauma. The first saliva samples were obtained immediately during the attacks and the second and third samples were obtained on the third and fifteenth days of the attack, respectively. In the controls, the first sample was obtained after admission to the hospital and the second sample was obtained on the third day. Salivary α-amylase levels were evaluated. The difference between salivary α-amylase levels in patients with MD and BPPV was not significant. The amylase value measured early after the BPPV attack was significantly lower than that of the controls (p = 0.008). Although not significant, an undulating pattern of salivary α-amylase levels was observed with both diseases. An autonomic imbalance could be partly demonstrated by salivary α-amylase measurement early after the attack in patients with BPPV. Therefore, amylase may be a promising marker that is worth further investigation.

Abstract
The sense of balance, which is usually barely noticeable in the background of each of our movements, only becomes manifest in its function during intense stimulation or in the event of illness, which may quite literally turn your world upside down. While it is true that balance is becoming a bigger issue, that is mainly because people are losing it more frequently. So why is balance not as commonly talked about in psychology, medicine or the arts as the other five traditional senses? This is partly due to its unusual multi-modal nature, whereby three sensory inputs are coordinated and integrated by the central nervous system. Without it, however, we might not have much use for the other senses. The sense of balance encompasses the bodily experience in its entirety. Not only do we act with the body, we may also think and feel through it and with it. Bodily states are not simply effects of cognition; they cause it as well. Equilibrioception is an essential sense and it is interconnected with a wide range of other areas, including cognition, perception, embodiment, the autonomic nervous system, aesthetics, the arts, and education.

Abstract
A 13-year-old boy with frequent episodes of vertigo and otologic symptoms was diagnosed with Ménière's disease (MD) but failed to respond to conventional treatment. Allergy testing revealed serious reactions to many allergens, and autonomic tests showed he was dysautonomic. An allergen-restricted diet and treatment of dysautonomia were effective, the boy being free from vertigo within 2 months. This case provides evidence to promote the understanding of MD in children. The authors hypothesize that the autonomic nerves and the immune system can interact, and that such an interaction of dysautonomia and allergy can lead to a serious vertigo episode.

PURPOSE Orthostatic dizziness (OD) and positional dizziness (PD) are considerably common conditions in dizziness clinic, whereas those two conditions are not clearly separated. We aimed to evaluate the clinical significance of simple OD and OD combined with PD for the diagnosis of benign paroxysmal positional vertigo (BPPV) and orthostatic intolerance (OI). PATIENTS AND METHODS Patients presenting with OD (n=102) were divided into two groups according to their symptoms: group PO, presenting with PD as well as OD; group O, presenting with OD. A thorough medical history, physical examination, and vestibular function tests were performed to identify the etiology of the dizziness. Orthostatic vital sign measurement (OVSM) was used to diagnose OI. RESULTS The majority of patients were in group PO (87.3%). BPPV was the most common cause of OD for entire patients (36.3%) and group PO (37.1%), while OI was most common etiology for group O (38.5%). Total of 17 (16.7%) OI patients were identified by OVSM test. Orthostatic hypotension (n=10) was most frequently found, followed by orthostatic hypertension (n=5), and orthostatic tachycardia (n=2). Group O showed significantly higher percentage (38.5%) of OI than group PO (13.5%) (P=0.039). CONCLUSION It is suggested that orthostatic testing such as OVSM or head-up tilt table test should be performed as an initial work up for the patients with simple OD. Positional tests for BPPV should be considered as an essential diagnostic test for patients with OD, even though their dizziness is not associated with PD.

Abstract
OBJECTIVE To elucidate the usefulness of clinical orthostatic blood pressure testing (COBP) as a screening tool for autonomic dysfunction. STUDY DESIGN In this retrospective case review, the records of 156 consecutive patients with nonotologic dizziness as the primary complaint seen in an academic neurotology clinic between 2005 and 2009 were reviewed. The objective of this study was accomplished by comparing the diagnostic yield of COBP with that of head-upright tilt table testing (HUT) and assessing the sensitivity and specificity of COBP in predicting an abnormal HUT in patients with nonotologic dizziness. SETTING Ambulatory tertiary referral center. PATIENTS Patients presenting to the clinic with dizziness without otologic cause. INTERVENTION(S) Clinical evaluation, orthostatic blood pressure testing, and HUT. MAIN OUTCOME MEASURE(S) The primary outcome assessed in this study was patient blood pressure. Blood pressures were measured in the clinic in the following order: supine, sitting, and standing. Positive COBP was defined as a reduction in systolic or diastolic blood pressure greater than 20 or 10 mm Hg, respectively, or both, within 3 minutes of sitting from supine or standing from sitting. For comparison, HUT was used as the gold standard. A positive HUT was defined as a reduction in systolic or diastolic blood pressure greater than 20 or 10 mm Hg, respectively, or both, relative to baseline at any point after initiation of HUT. RESULTS Forty patients were referred for HUT. Twenty-four (61.5%) of these patients were deemed to have a positive response. Thirty-three patients (85%) referred to HUT were initially evaluated with COBP, which revealed orthostatic hypotension (OH) in 8 patients (24%). COBP was calculated to have sensitivity and specificity of 21% and 71%, respectively, when asymptomatic OH was included in the positivity criteria. When asymptomatic OH was excluded from the positivity criteria, the sensitivity and specificity remained similar at 25% and 76%, respectively. However, the exclusion of asymptomatic OH from the positivity criteria resulted in a decrease in the positive predictive value from 50% to 25% and an increase in the negative predictive value from 40% to 76%. Overall, HUT detected 16 patients with an abnormal result that were missed by COBP testing. CONCLUSION Evaluation for autonomic dysfunction should be part of the comprehensive evaluation of a dizzy patient, involving, at a minimum, orthostatic testing of blood pressure and heart rate. Patients with nonotologic dizziness and light-headedness with a normal neurotologic evaluation can reasonably be referred for HUT, even in the presence of normal in-office orthostatic testing.

Abstract
Deviations from normal blood pressure can lead to a number of physiological and behavioral complications. We tested the hypothesis that hyper- or hypotension is associated with significant differences in motor activity and coordination, anxiety levels, and spatial learning and memory in male and female mice. Compared to normotensive control mice, hypertensive mice were hyperactive and their performance was significantly worse on the rotarod (males only), cued learning (males only), spatial learning/re-learning, and spatial memory. Hypotensive mice of both genders swam more slowly and performed even worse than hypertensive mice on the rotarod, cued learning, spatial learning/re-learning, and spatial memory tasks. Across all phenotypes, females were generally more active than males in the open field and exhibited more anxiety-like behaviors in the elevated zero maze. Alterations in hemodynamics and/or neurovascular unit function may account for the observed behavioral changes in the hypo- and hypertensive mice.

Abstract
PURPOSE To evaluate the incidence of coexistent peripheral vestibular dysfunction and cardiovascular autonomic dysfunction in patients undergoing evaluation for dizziness exacerbated by postural changes. MATERIALS AND METHODS Retrospective case review of 56 sequential patients seen from 2003 to 2006 at a tertiary center for a primary complaint of dizziness who underwent both passive tilt table testing for evaluation of neurocardiogenic etiology and quantitative vestibular testing. The vestibular test battery consisted of alternating bithermal caloric testing; computerized sinusoidal vertical axis rotation (at frequencies 0.01-0.64) with infrared videonystagmography; and oculomotor and positional testing including bilateral Dix-Hallpike, head center supine, and 30-degree supine head turns right and left. RESULTS Eight of the 56 subjects had caloric weakness. Forty-five subjects (80%) had abnormal tilt table test findings. The incidence of coexistent neurocardiogenic and vestibular test abnormalities was 10.7%. There was no significant association between abnormal tilt table test result and caloric weakness (Fisher exact test; P = .64). The degree of compensation seen on vestibule-ocular reflex gain testing did not affect tilt table findings (chi2; P = .872). CONCLUSIONS There is no difference in the rate of postural orthostatic intolerance in subjects with evidence of caloric weakness compared with those with normal caloric function.

Abstract
OBJECTIVES To assess how frequently cardiovascular dizziness is vertigo. Recent studies suggest providers do not consider cardiovascular causes when a patient reports true vertigo (spinning/motion) as opposed to presyncope (impending faint). It is known that cardiovascular disease causes dizziness, but unknown how often such dizziness is vertiginous, as opposed to presyncopal. DATA SOURCES Systematic review of observational studies was made: Search--electronic (MEDLINE, EMBASE) and manual (references of eligible articles) search for English-language studies (1972-2007). REVIEW METHODS Inclusions Studies of >or=5 patients with confirmed cardiovascular causes for dizziness and reporting a proportion with vertigo were included. Two independent reviewers selected studies for inclusion, with differences adjudicated by a third. Study characteristics and dizziness-type proportions were abstracted. Studies were rated on methodology and quality of dizziness definitions. Differences were resolved by consensus. RESULTS We identified 1,506 citations, examined 125 full manuscripts, and included 5 studies. Principal reasons for exclusion were: abstracts--lack of original data, no cardiovascular diagnosis, or confounding exposure/disease (74%); manuscripts--failure to distinguish vertigo from other dizziness types (78%). In the three studies not using vertigo as an entry criterion (representing 1,659 patients with myocardial infarction, orthostatic hypotension, or syncope), vertigo was present in 63% (95% CI 57-69%) of cardiovascular patients with dizziness and the only dizziness type in 37% (95% CI 31-43%). Limitations include modest study quality and non-uniform definitions for vertigo. CONCLUSIONS Published data suggest that dizziness from primary cardiovascular disease may often be vertigo. Future research should assess prospectively whether dizziness type is a meaningful predictor for or against a cardiovascular diagnosis.

Psychiatric comorbidity in different organic vertigo syndromes. J Neurol 2008; 255:420-8. [PMID: 18338198 DOI: 10.1007/s00415-008-0697-x] [Citation(s) in RCA: 148] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2007] [Revised: 07/10/2007] [Accepted: 07/10/2007] [Indexed: 10/22/2022]
Abstract
OBJECTIVE A high degree of psychiatric disorders has repeatedly been described among patients with organic vertigo syndromes and attributed to vestibular dysfunction. Yet almost no investigations exist which differentiate between various organic vertigo syndromes with regard to psychiatric comorbidity. The following prospective, interdisciplinary study was carried out to explore whether patients with different organic vertigo syndromes exhibit different psychological comorbidities. METHODS 68 patients with organic vertigo syndromes (benign paroxysmal positioning vertigo (BPPV) n = 20, vestibular neuritis (VN) n = 18, Menière's disease (MD) n = 7, vestibular migraine (VM) n = 23) were compared with 30 healthy volunteers. All patients and control persons underwent structured neurological and neuro-otological testing. A structured diagnostic interview (-I) (SCID-I) and a battery of psychometric tests were used to evaluate comorbid psychiatric disorders. RESULTS Patients with VM and MD showed significantly higher prevalence of psychiatric comorbidity (MD = 57%, VM = 65%) especially with anxiety and depressive disorders, than patients with VN (22%) and BPPV (15 %) compared to normal subjects (20 %). These elevated rates of comorbidities resulted in significantly elevated odds-ratios (OR) for the development of comorbid psychiatric disorders in general (for VM OR = 7.5, for MD OR = 5.3) and especially for anxiety disorders (for VM OR = 26.6, for MD OR = 38.7). CONCLUSION As a consequence, a structured psychological and psychometric testing and an interdisciplinary therapy should be proceeded in cases with complex and prolonged vertigo courses, especially in patients with VM and MD. Possible reasons of these unexpected results in VM and MD are discussed.

Abstract
CONCLUSIONS Dysautonomia is a multisystem disorder. Beside the nasal symptoms, some otolaryngological disorders may be explained on the basis of autonomic dysfunction. Testing of the autonomic nervous system (ANS) complements the clinical findings and provides objective measurements to substantiate the presence of ANS dysfunction. The term dysautonomia rhinitis may be used to specify this autonomic-related rhinitis. OBJECTIVES Nonallergic, noninfectious perennial rhinitis is a heterogeneous disorder comprising several pathophysiological entities. This study was designed to objectively investigate the relation of idiopathic perennial rhinitis to ANS dysfunction. PATIENTS AND METHODS This was a prospective controlled clinical study; 78 patients, carefully diagnosed as having idiopathic perennial rhinitis, were enrolled. Workshop protocol included diagnostic measures for exclusion of other causes of rhinitis and autonomic function assessment at a clinical cardiology laboratory. Results were compared with those of 20 age- and sex-matched normal control subjects. RESULTS In addition to their nasal symptoms, all patients reported more than one regional and multisystem complaint. Each patient had at least one autonomic function test that displayed a hypervagal response and the overall response score was as follows: 46 (59%) had hypervagal response, 32 (41%) had mixed response and none had a normal or hyperadrenergic response.
