Severity-dependent variations of the neutrophil to lymphocyte ratio (NLR) in peripheral vestibular vertigo

Background Peripheral vestibular vertigo is a common cause of vertigo especially in the elderly. The neutrophil to lymphocyte ratio (NLR) is a rapid and cost-effective inflammatory marker that has been assessed previously in peripheral vestibular disorders. However, its relation to the severity of peripheral vertigo has not been previously investigated. The aim of this study is to assess the levels of NLR in peripheral vestibular vertigo of various severity categories. This was a cross-sectional study at the Wahidin Sudirohusodo Hospital and Hasanuddin University Teaching Hospital in Makassar. The NLR was measured among subjects with periphel vestibular vertigo with severity categorised using the Dizziness Handicap Inventory (DHI) questionnaire. Results A total of 39 participants with peripheral vestibular vertigo were recruited. A statistically significant difference was found (p = 0.002, Kruskal–Wallis ANOVA) between the mean NLR for the mild, moderate, and severe DHI categories were 2.47 ± 1.66, 2.64 ± 0.96, and 5.15 ± 2.59 respectively. Conclusion A significant difference in the NLR was found between the three different vertigo severity groups, wherein NLR values rise with increase in vertigo severity. This warrants further exploration on the role of inflammatory biomarkers in vertigo pathophysiology and clinical assessment.

Для объективизации головокружения применяли специализированные тесты функциональной компьютерной стабилометрии. Проведенное исследование позволило выявить особенности базовых стабилометрических параметров в специализированных тестах у пожилых пациентов, которые можно использовать для получения количественной оценки вестибулярной дисфункции и объективизации головокружения. The purpose of the study was to study the possibility of computer stabilometric diagnostics for the objectification of vertigo in elderly patients with vestibular migraine. The study included 57 elderly patients with vestibular migraine and 57 elderly patients with central vestibular vertigo, without migraine. Specialized tests of functional computer stabilometry were used to objectify vertigo. The study revealed the features of the basic stabilometric parameters in specialized tests in elderly patients, which can be used to obtain a quantitative assessment of vestibular dysfunction and objectification of vertigo.

Vestibular vertigo in emergency neurology

The review deals with approaches to the differential diagnosis of the causes of vertigo in emergency neurology. The main causes of episodic and acute vestibular syndrome are discussed. Clinical diagnostic methods for acute vestibular syndrome (evaluation of nystagmus, test of skew, head-impulse test and neurological status) are considered. Clinical signs of “benign” acute vestibular syndrome and symptoms indicating a stroke in the vertebrobasilar system are presented. Differential diagnostic criteria for peripheral and central vestibular disorders are presented. Transient ischemic attacks, features of the otoneurologic status in vestibular neuronitis and different localizations of cerebral infarction focus are considered. Errors in the diagnosis of the vertigo causes are discussed.

Efficacy and Pharmacological Appropriateness of Cinnarizine and Dimenhydrinate in the Treatment of Vertigo and Related Symptoms

Vertigo is not itself a disease, but rather a symptom of various syndromes and disorders that jeopardize balance function, which is essential for daily activities. It is an abnormal sensation of motion that usually occurs in the absence of motion, or when a motion is sensed inaccurately. Due to the complexity of the etiopathogenesis of vertigo, many pharmacological treatments have been tested for efficacy on vertigo. Among these drugs, cinnarizine, usually given together with dimenhydrinate, appears to be the first-line pharmacotherapy for the management of vertigo and inner ear disorders. Based on these considerations, the present non-interventional study aimed to investigate the clinical efficacy and tolerability of a fixed combination of cinnarizine (20 mg) and dimenhydrinate (40 mg) in patients suffering from vertigo-related symptoms. To this end, we enrolled 120 adults—70 males, and 50 females—with an average age of 64 years. Before beginning pharmacological treatment, all patients were screened for the intensity of vertigo, dizziness, and concomitant symptoms through the Visual Scale of Dizziness Disorders and Dizziness Handicap Inventory scales. At the end of the anamnestic evaluation, patients received the fixed-dose combination of cinnarizine (20 mg) plus dimenhydrinate (40 mg) 3 times daily, for 60 days. The results of this study provide further insight regarding the efficacy of the fixed combination when used to reduce symptoms of vestibular vertigo of central and/or peripheral origin, after both the 15- and 60-day therapies. Independent of the type of vertigo, the fixed combination was able to reduce dizziness- and vertigo-associated symptoms in more than 75% of all patients treated, starting from 15 days of therapy, and improving 60 days after starting the therapy. Interestingly, we also found differences between male and female patients in the framework of the pharmacological effects of therapy. This study provides further details concerning the therapeutic efficacy of the fixed combination of cinnarizine and dimenhydrinate, and also focuses attention on the possibility that these drugs could act in a gender-specific manner, paving the way for further research.

Drug and non-drug treatments of vertigo

Patients with complaints of “dizziness” often make an odyssey of visits to physicians belonging to various specialties. The prevalence of vertigo in the population is 17–30%. In most cases, disorders of various areas of the vestibular analyzer form the pathogenetic basis of vertigo and unsteadiness, while the most common cause of these complaints is the pathology of the peripheral area of the vestibular system: benign paroxysmal positional vertigo, vestibular neuronitis, Meniere’s disease. The cerebral vessel disease caused by hypertensive cerebral microangiopathy and cerebral atherosclerosis can also manifest by vertigo and unsteadiness. They can be represented by acute cerebrovascular disorders in the vertebrobasilar arterial system, transient ischemic attacks, as well as manifestations of chronic cerebrovascular disease (chronic cerebral ischemia, discirculatory encephalopathy). Episodes of recurrent spontaneous vestibular vertigo can be caused by vestibular migraine, which is rarely diagnosed in our country. The variety of reasons for complaints of vertigo and unsteadiness defines many therapeutic approaches to the treatment of these diseases. In recent times, modern drug and non-drug approaches to the treatment have been developed for patients with various diseases manifested by vertigo and unsteadiness. The most effective treatment is a comprehensive therapeutic approach that combines non-drug therapy, including vestibular gymnastics, training on the stabilographic platform with biofeedback according to the support reaction, and drugs that help reduce the severity, duration, and frequency of vertigo attacks, as well as accelerate vestibular compensation. Many studies have shown the efficacy of drugs enhancing microcirculation used for the prophylactic treatment of various causes of vertigo and unsteadiness.

Modern approaches to drug treatment for vestibular vertigo

In recent years, some progress has been achieved in elaborating the algorithms and standards for the treatment of many conditions accompanied by vertigo. The current possibilities of treating vestibular vertigo consist of a gradually expanding arsenal of symptomatic and pathogenetic drugs. Among the drugs used for the symptomatic treatment of vestibular vertigo, there are vestibular suppressants (antihistamines, benzodiazepines, and calcium antagonists) and antiemetics (dopamine antagonists and serotonin 5-HT3 receptor antagonists). The paper discusses the possibilities of using betahistine and vitamin D as pathogenetic agents for recurrent benign paroxysmal positional vertigo; diuretics, betahistine (including the new prolonged release formulation Betaserc® Long), glucocorticoids, and gentamicin for Meniere's disease; triptans, beta-blockers, tricyclic antidepressants, and anticonvulsants for vestibular migraine; glucocorticoids, antiviral agents, and drugs that accelerate vestibular compensation for acute unilateral peripheral vestibulopathy (vestibular neuritis and Ramsey Hunt syndrome).The emergence of new drugs, as well as the design of new dosage forms that enhance patient adherence to the prescribed treatment, can improve quality of life in patients suffering from diseases that have recently led to long-term disability or even incapacitation.

Clinical manifestations and issues of diagnosis of chronic cerebrovascular disease (chronic cerebral ischemia) at an early (pre-dementia) stage

The paper presents experts' opinion on the clinical manifestations and diagnosis of chronic cerebrovascular disease (CVD) (chronic cerebral ischemia (CCI) and dyscirculatory encephalopathy (DEP)) at the pre-dementia stage. It is noted that DEP/CCI is a common diagnosis in Russian neurological practice, the criteria for which have not been updated for a long time. DEP/CCI most often develops in the presence of cerebral small artery (CSA) disease (cerebral microangiopathy (CMA)), the severity of which can be quantified by magnetic resonance imaging. The main clinical manifestation of DEP/CCI is cognitive impairment that may be subjective or moderate at the pre-dementia stage. Emotional disorders (apathy, depression, anxiety) and instability are considered as possible manifestations of CSA disease. It is noted that headache and vestibular vertigo are not caused by chronic CVD; while in patients with CMA, they are usually associated with other diseases (primary headache, peripheral vestibular vertigo, and vestibular migraine). The diagnosis of DEP/CCI should be based on the presence of cognitive impairment, reliable neuroimaging signs of CVD, and the exclusion of another cause of cognitive impairment.

Cervicogenic and Vestibular Vertigo-Bridging the Gap

The diagnosis and management of vertigo is still a challenge. Vertigo is managed by heterogenous group of specialists, including Otolaryngologists, Neurologists and Physiotherapists. The cause of vertigo could be vestibular, central or cervicogenic. The current review was undertaken as an attempt to highlight the various gaps in knowledge about vertigo of varied aetiologies. Cervicogenic vertigo is caused due to neck pathologies and is considered by some authors to be one of the most common vertigo syndromes. However, there is little mention of it in otolaryngology textbooks. Barriers across the specialties and lack of communication between the specialists are an impediment in vertigo management. This review has attempted to highlight the likely multifactorial aetiologies and fallacies in the pathophysiology of Meniere’s disease. The clinical overlaps in cervicogenic and vestibular vertigo have been discussed, some of them being, the occurrence of aural symptoms and neck pain in both the entities. This review article brings out the need to revisit the pathophysiology of vestibular vertigo syndromes and include cervicogenic dizziness in the list of vertigo syndromes in Otolaryngology textbooks. The authors found a dire need of an interdisciplinary approach to elucidate the cause of vertigo of varied presentation with the goal of better patient management.

Burden of vertigo at home: Risks for patients with vertigo

Objective We aimed to clarify the burden of vertigo in patients’ homes. Methods This was a questionnaire survey among patients with vestibular vertigo. Four main questions were prepared. Q1: Where did you first notice vertigo? Q2: Where have you had the most difficulty with vertigo in your home? Q3: Where do you have difficulty at present? Q4: What household equipment have you used as a countermeasure to prevent further problems with vertigo? Results Sixty patients completed the questionnaire. Benign paroxysmal positional vertigo (BPPV) was most common among respondents, followed by Ménière’s disease. Q1: Most patients with BPPV first noticed vertigo in the bedroom; patients with other diseases first noticed vertigo in the living room. Q2: Both groups previously had the most difficulty with vertigo in the same locations as in Q1; these differences were significant between Q1 and Q2. Q3: Both groups had the most difficulty on stairs. Q4: Handrails were the most often used equipment for vertigo in both groups. There was no significant difference between Q3 and Q4. Conclusion Our data revealed that the locations of risks differ among patients with vestibular disorders. Handrails were considered the most important equipment to prevent problems with vertigo.
