Evaluation of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in essential tremor

TAK Zeynal Abidin Ali, SENGUL Yildizhan

Introduction - Although essential tremor (ET) is the most common cause of tremor, the pathology and underlying mechanisms have not fully understood yet. In addition to kinetic tremor, patients may present several types of tremor, gait ataxia, hearing deficits and eye movement abnormalities. Non-motor symptoms and signs have also added to definition of ET. There is significant evidence indicating the neurodegenerative nature of the disease. New studies indicate that inflammation may have a place in the etiology. The neutrophil-to lymphocyte ratio (NLR) and the platelet-to lymphocyte ratio (PLR) have recently begun to be used as a marker of systemic inflammation. Our study aims at finding a clue for systemic inflammation in ET. Methods - 67 patients with ET and 40 healthy controls were recruited for the study. The total white blood cells (WBC), absolute neutrophil count, lymphocyte count and platelet count were retrieved. The NLR was calculated by dividing the neutrophil count by the lymphocyte count and the PLR was calculated by dividing the platelet count by the lymphocyte count. Results - Patient and control groups were similar in terms of age and gender. The mean age of patient group was 25.29 ± 8.24 years and that of control group was 26.77 ± 6.73 years. The NLRs were 1.85 ± 0.58 in the patient group and 1.96 ± 0.53 in the control group. For the patient group and the control group the PLRs were 103.52 ±32.80 and 91.26 ± 31.57 respectively. There were no statistically significant differences between the participants for both NLR and PLR. Conclusion - The pathophysiological mechanism for essential tremor (ET) remains unclear. However, there is an increasing amount of research being conducted on the subject. Discussions about ET’s definition as a neurodegenerative disease are ongoing. Although previous studies showed that neuroinflammation could be a part of etiology of disease, this study has failed to demonstrate systemic inflammation in ET.

Inflammatory biomarkers in benign paroxysmal positional vertigo: A Turkey case-control study


Objective - Benign paroxysmal positional vertigo (BPPV) is the most common cause of recurrent vertigo. Inflammation is a hypothetic etiological factor in BPPV. The aim of this study was to evaluate inflammatory biomarker levels in BPPV patients and compare these with the healthy subjects. Materials and methods - This prospective case-control study was conducted with 114 newly diagnosed BPPV patients and age- and sex- matched 83 healthy subjects. The laboratory investigations included serum hemogram, full biochemistry profiles, vitamin levels, thyroid hormone profiles, high sensitivity C-reactive protein (hsCRP) and erythrocyte sedimentation rate (ESR). Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte to HDL-cholesterol ratio (MHR) values were calculated and compared between the patients and healthy subjects. Results - The mean age was 39.1 ± 12.4 years for patients, and 37.0 ± 11.9 for controls. Vitamin B12, hematocrit (Hct), creatinine, urea, and fT4 values, lymphocyte, total bilirubin, direct bilirubin and indirect bilirubin levels were significantly lower in BPPV patients (p ˂ 0.05), while HDL, SGOT, and ESR values were significantly higher. In the BPPV patients the mean NLR, PLR, and mean platelet volume (MPV) values were significantly higher than in the control subjects. Neutrophil, platelet, monocyte, MHR, and CRP values were similar in both groups (p ˃ 0.05). Conclusion - Our result suggests that NLR, PLR, MPV, ESR, and bilirubin levels should be taken into account as potential biomarkers of BPPV. As they are inexpensive parameters and widely available, they can be used in clinical practice for prediction of BPPV. However, further large-scale studies are required to confirm this relationship.

[Epidemiology, comorbidity, etiology of depression and cardiovascular diseases]

PÉTER László, RIHMER Zoltán

[Psychiatric problems are a common comorbid condition in patients with cardiovascular disease. Depression is a well-known risk factor for the development of cardiovascular disease and mortality too. Psychiatric and cardiovascular diseases are prevalent public health problems in the western world. Depression is associated with endo­thelial dysfunction and increased platelet aggregation, which may explain the consequent cardiovascular complications. Specific affective temperaments may be associated with special cardiovascular diseases. Antidepressant therapy does not only reduce depression but also cardiac mortality.]

[Medical therapy of peripherial artery disease]


[Care of PAD (peripherial arterial disease) is one of the most negligent area of cardiovascular diseases: on one hand patients suffering from PAD are the most uncared, less educated and health-minded population (it’s enough to keep in mind the high rate of smoking and alcohol-abuse among them) in addition the number of angiologists is insufficient for the treatment of PAD. Although detection of PAD would be easy as a widely applicable, cheap screening method, the ankle-brachial index is available which is an obligatory screening investigation in general care. Therapeutic options are better and better since cilostazol was launched we have an evidence-based treatment which can solve the symptoms, slower the progression which is strongly recommended (IA recommendation) in both American and Hungarian guidelines. Cilostazol, a PDE3-inhibitor has complex pharmacological effect but contraindicated in several clinical conditions as pentoxiphylline is not totally excluded from the therapeutic arsenal of PAD. The place of antiplatelet agents is well-defined in the most recent European guidelines in the treatment of PAD. The jumping development of interventional radiology beyond medical therapy contributed a lot to prevent limb amputations in the case of early detection of PAD. ]
