Disrupted Neural Regeneration in Dry Eye Secondary to Ankylosing Spondylitis-With a Theoretical Link between Piezo2 Channelopathy and Gateway Reflex, WDR Neurons, and Flare-Ups. Int J Mol Sci 2023; 24:15455. [PMID: 37895134 PMCID: PMC10607705 DOI: 10.3390/ijms242015455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 10/20/2023] [Accepted: 10/21/2023] [Indexed: 10/29/2023] Open
Abstract
This study aimed at analyzing the corneal neural regeneration in ankylosing spondylitis patients using in vivo corneal confocal microscopy in correlation with Langerhans cell density, morphology, and dry eye parameters. Approximately 24 ankylosing spondylitis subjects and 35 age- and gender-matched control subjects were enrolled. Data analysis showed that all corneal nerve-fiber descriptives were lower in the ankylosing spondylitis group, implicating disrupted neural regeneration. Peripheral Langerhans cell density showed a negative correlation with nerve fiber descriptions. A negative correlation between tear film break-up time and corneal nerve fiber total branch density was detected. The potential role of somatosensory terminal Piezo2 channelopathy in the pathogenesis of dry eye disease and ankylosing spondylitis is highlighted in our study, exposing the neuroimmunological link between these diseases. We hypothesized earlier that spinal neuroimmune-induced sensitization due to this somatosensory terminal primary damage could lead to Langerhans cell activation in the cornea, in association with downregulated Piezo1 channels on these cells. This activation could lead to a Th17/Treg imbalance in dry eye secondary to ankylosing spondylitis. Hence, the corneal Piezo2 channelopathy-induced impaired Piezo2-Piezo1 crosstalk could explain the disrupted neural regeneration. Moreover, the translation of our findings highlights the link between Piezo2 channelopathy-induced gateway to pathophysiology and the gateway reflex, not to mention the potential role of spinal wide dynamic range neurons in the evolution of neuropathic pain and the flare-ups in ankylosing spondylitis and dry eye disease.

Abstract
The purpose of our study was to analyze abnormal neural regeneration activity in the cornea through means of confocal microscopy in rheumatoid arthritis patients with concomitant dry eye disease. We examined 40 rheumatoid arthritis patients with variable severity and 44 volunteer age- and gender-matched healthy control subjects. We found that all examined parameters were significantly lower (p < 0.05) in rheumatoid arthritis patients as opposed to the control samples: namely, the number of fibers, the total length of the nerves, the number of branch points on the main fibers and the total nerve-fiber area. We examined further variables, such as age, sex and the duration of rheumatoid arthritis. Interestingly, we could not find a correlation between the above variables and abnormal neural structural changes in the cornea. We interpreted these findings via implementing our hypotheses. Correspondingly, one neuroimmunological link between dry eye and rheumatoid arthritis could be through the chronic Piezo2 channelopathy-induced K2P-TASK1 signaling axis. This could accelerate neuroimmune-induced sensitization on the spinal level in this autoimmune disease, with Langerhans-cell activation in the cornea and theorized downregulated Piezo1 channels in these cells. Even more importantly, suggested principal primary-damage-associated corneal keratocyte activation could be accompanied by upregulation of Piezo1. Both activation processes on the periphery would skew the plasticity of the Th17/Treg ratio, resulting in Th17/Treg imbalance in dry eye, secondary to rheumatoid arthritis. Hence, chronic somatosensory-terminal Piezo2 channelopathy-induced impaired Piezo2-Piezo1 crosstalk could result in a mixed picture of disrupted functional regeneration but upregulated morphological regeneration activity of these somatosensory axons in the cornea, providing the demonstrated abnormal neural corneal morphology.

Abstract
This study aims to measure the effects of two different exercise programs on neck pain, proprioception, balance, coordination, posture, and quality of life in patients with Chiari malformation (CM) type 1. Sixteen patients were randomized to two different exercise programs: a tailored exercise protocol for CM (TEP-CM) and cervical spinal stabilization exercises (CSSE). Both exercise programs were implemented by a physiotherapist 3 days a week for 6 weeks. The primary outcome was Neck Disability Index. Secondary outcomes were visual analogue scale for pain, joint position sense error measurement, Berg Balance Scale, Time Up and Go Test, International Coordination Ataxia Rating Scale, PostureScreen Mobile, and Short Form-36. Assessments were done immediately before and after the intervention programs. Both groups showed significant improvement in Neck Disability Index, and some secondary outcome measures (P < 0.05). However, there were no statistical differences in post-intervention changes between the groups (P > 0.05). This is the first study to examine the effects of different exercise programs on symptoms in patients with CM type 1. Our preliminary findings indicate that exercise programs can improve pain, balance, proprioception, posture, coordination, and quality of life in CM type 1. Therefore, exercise should be considered safe, beneficial, and low-cost treatment option for CM type 1 patients without surgical indications.

A Reliability of Active and Passive Knee Joint Position Sense Assessment Using the Luna EMG Rehabilitation Robot. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15885. [PMID: 36497961 PMCID: PMC9739924 DOI: 10.3390/ijerph192315885] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Revised: 11/21/2022] [Accepted: 11/25/2022] [Indexed: 06/17/2023]
Abstract
Joint position sense (JPS) is the awareness of joint location in space, indicating accuracy and precision of the movement. Therefore, the aim of the present study is to determine the reliability of active and passive JPS assessment regarding the knee joint. This was carried out using the Luna EMG rehabilitation robot. Further analysis assessed whether the examination of only the dominant site is justified and if there are differences between sites. The study comprised 24 healthy male participants aged 24.13 ± 2.82 years, performing sports at a recreational level. Using the Luna EMG rehabilitation robot, JPS tests were performed for the right and left knees during flexion and extension in active and passive mode, in two separate sessions with a 1-week interval. Both knee flexion and extension in active and passive modes demonstrated high reliability (ICC = 0.866-0.982; SEM = 0.63-0.31). The mean JPS angle error did not differ significantly between the right and left lower limbs (p < 0.05); however, no between-limb correlation was noted (r = 0.21-0.34; p > 0.05). The Bland-Altman plots showed that the between-limb bias was minimal, with relatively wide limits of agreement. Therefore, it was concluded that the Luna EMG rehabilitation robot is a reliable tool for active and passive knee JPS assessment. In our study, JPS angle error did not differ significantly between left and right sides; however, the slight asymmetry was observed (visible in broad level of agreement exceeding 5° in Bland-Altman plots), what may suggest that in healthy subjects, e.g., active athletes, proprioception should always be assessed on both sides.

Abstract
To investigate the effect of a structured exercise training program on pain, functional status, physical function and quality of life (QoL) in string and woodwind players with nonspecific cervical pain. This study had a prospective cohort design and conducted on 40 musicians (26 male, 14 female) aged between 18 and 65 years with persistent nonspecific neck pain in the previous 3 months. Forty musicians were assigned to either violin (n = 20, median age; 26.5 year, height; 1.67 m, body mass; 65 kg, BMI; 23.04 kg/m2) or ney group (n = 20, median age; 27.5 year, height; 1.81 m, body mass; 75 kg, BMI; 23.35 kg/m2) and followed the same structured exercise program (3 days/per week for 8 weeks). The primary outcome was neck pain intensity and assessed on a visual analog scale (VAS). Secondary outcomes; cervical range of motion (ROM) was measured using a goniometer, the jaw-to-sternum and jaw-to-wall distances were used for the assessment of cervical mobility, neck, shoulder and back muscles strength were assessed with a hand-held dynamometer, the Northwick Park Neck Pain and Short Form 36 (SF-36) questionnaires were also used. Normality of data distribution was checked using the Kolmogorov-Smirnov test. For evaluating the training effectiveness on outcome measures, Mann-Whitney U and Wilcoxon test were used compare pre-test and post-test values with/within groups, respectively. The primary outcome (pain intensity) was lowered %33 in both groups. However, the mean change was found similar (median mean changes; -2 for both groups) (p > 0.05). The secondary outcomes; cervical mobility, cervical flexion ROM, disability and muscle strength of the left middle trapezius, left hand grip, anterior and middle parts of the right deltoid, and cervical flexors also significantly improved in both groups (p < 0.05). Only the mean changes of right serratus anterior, middle trapezius and cervical flexor muscles were higher in violin group than ney group (p < 0.05). There was no significant difference in the cervical extension, right rotation, left rotation, right lateral flexion and left lateral flexion after the treatment in both groups (p > 0.05). There was no significant difference between the groups after the exercise program in terms of pain, mobility, range of motion and SF-36 subdomains (p > 0.05). Specific exercise program had similar positive effects on pain, cervical mobility, cervical fexion ROM and disability in string and woodwind players. Although several muscles showed similar improvements in strength, some muscle groups recovered differently. Physical needs specific to the instrument and performance should be taken into account when prescribing exercises to musicians having the same problem, but playing different instruments.

Abstract
Proprioceptive abnormalities, balance, and postural disorders have been previously reported in fibromyalgia syndrome (FMS). Unlike previous research, the aim of this study was to compare the proprioception of the cervical region of patients with FMS with a healthy control group. The relationship between cervical proprioception impairment and loss of balance was also examined. A total of 96 female FMS patients and 96 female healthy control subjects were enrolled in this case-control study. The cervical joint position error test (CJPET) was administered to the patient and control groups for cervical proprioception evaluation. FMS patients were assessed with a visual analogue scale (VAS), fibromyalgia impact questionnaire (FIQ), and fatigue severity scale (FSS). Balance tests were applied to both groups. FMS patients had significantly impaired CJPET results in all directions (p < 0.001). There were significant positive correlations between FIQ scores and CJPET results (r = 0.542 and p < 0.001 for right rotation; r = 0.604 and p < 0.001 for left rotation; r = 0.550 and p < 0.001 for flexion; r = 0.612 and p < 0.001 for extension). Significant correlations were found between CJPET measurements and balance tests (for sit-to-stand test; r = 0.510 and p < 0.001 for right rotation; r = 0.431 and p < 0.001 for left rotation; r = 0.490 and p < 0.001 for flexion; r = 0.545 and p < 0.001 for extension), (for timed up and go test; r = 0.469 and p < 0.001 for right rotation; r = 0.378 and p < 0.001 for left rotation; r = 0.410 and p < 0.001 for flexion; r = 0.496 and p < 0.001 for extension) and (for one-legged balance test; r = -0.479 and p < 0.001 for right rotation; r = -0.365 and p < 0.001 for left rotation; r = -0.392 and p < 0.001 for flexion; r = -0.469 and p < 0.001 for extension). Cervical proprioception and balance were impaired in FMS patients. As the disease activity and fatigue level increased, so the deterioration in cervical proprioception became more evident. There were correlations that demonstrated an association between impaired cervical proprioception and poor balance tests. Therefore, proprioception and balance assessments should be integrated into the physical examination processes of FMS patients.

Abstract
Although synovitis is the pathological hallmark of rheumatoid arthritis (RA), many extra-articular manifestations (EMs) and comorbidities likely occur due to the complex, chronic, inflammatory, and autoimmune features of RA. Cardiovascular (CV) disease is the most common cause of death in patients with RA. Compared to the general population, patients with RA have twice the risk of myocardial infarction and up to 50% increased CV mortality risk. Severe and prolonged disease activity, genetics, and inflammation (e.g. CRP, ACPA, cytokines, matrix-degrading enzymes) play important roles in CV disease and atheroscleroticdamage. The second major cause of death in patients with RA is respiratory disease, which occurs in 30-40% of patients. RA may affect the lung interstitium, airways, and pleurae, while pulmonary vascular involvement is less frequent. Central and peripheral nervous system involvement is usually due to small vessel vasculitis, joint damage, or drug toxicity. There is also evidence that microvascular cerebral damage caused by systemic inflammation is associated with the development of Alzheimer's disease and vascular dementia. Some observational studies have hinted how Disease Modified Anti-Rheumatic Drugs and biologics could reduce the incidence of dementia. Primary gastrointestinal and renal involvements are rare and often relate to drug therapy. To minimize morbidity and mortality, physicians must manage RA disease activity (treat-to-target) and monitor risk factors and concomitant conditions (e.g. smoking cessation; weight regulation; monitoring blood pressure, lipids, thyroid hormone, folic acid and homocysteine; screening for depression, anxiety, atlantoaxial instability, and atherosclerosis). This article aims to provide an overview of the most prevalent and important EMs and comorbidities associated with RA.

Abstract
BACKGROUND Proprioception is the awareness of body parts and includes joint position sense, kinesthesia, and sense of force. Cervical spine is one of the major affected areas in axial spondyloarthritis (axSpA), and is an essential region for proprioceptive receptors. OBJECTIVE To investigate the cervical joint proprioceptive accuracy by using cervical joint positioning error (JPE) method in patients with axSpA and healthy controls. DESIGN Cross-sectional study. METHODS JPE was calculated for cervical motions in the directions of flexion, extension, rotations, and lateral flexions. Time since diagnosis, symptom duration, spinal mobility, functional status, quality of life, disease activity, and pain were evaluated in axSpA patients. Cervical JPE of axSpA patients was also compared according to radiographic status, biologic use, and existence of cervical syndesmophytes. RESULTS Eighty-two axSpA patients (52 males) and 71 healthy subjects (53 males) were evaluated. Cervical JPE was higher in patients with axSpA compared to healthy subjects (p < 0.001), except left lateral flexion (p = 0.10). Cervical proprioceptive accuracy for extension and left rotation was better in biologics+ subgroup compared to biologic- subgroup (p < 0.05). No other differences were detected related to radiographic status nor existence of cervical syndesmophytes (p > 0.05). CONCLUSION Cervical proprioception accuracy is impaired in patients with axSpA. It seems that controlling disease activity by using appropriate medication may have a positive effect on cervical proprioception accuracy.

Abstract
Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory autoimmune disease that affects about 1% of the global population, with a female–male ratio of 3:1. RA preferably affects the joints, with consequent joint swelling and deformities followed by ankylosis. However, evidence has accumulated showing that patients suffering from RA can also develop extra-articular manifestations, including cardiovascular disease states, neuropathies, and multiorgan dysfunction. In particular, peripheral nerve disorders showed a consistent impact in the course of the disease (prevalence about 20%) mostly associated to vasculitis of the nerve vessels leading to vascular ischemia, axonal degeneration, and neuronal demyelination. The pathophysiological basis of this RA-associated microvascular disease, which leads to impairment of assonal functionality, is still to be better clarified. However, endothelial dysfunction and alterations of the so-called brain-nerve barrier (BNB) seem to play a fundamental role. This review aims to assess the potential mechanisms underlying the impairment of endothelial cell functionality in the development of RA and to identify the role of dysfunctional endothelium as a causative mechanism of extra-articular manifestation of RA. On the other hand, the potential impact of lifestyle and nutritional interventions targeting the maintenance of endothelial cell integrity in patients with RA will be discussed as a potential option when approaching therapeutic solutions in the course of the disease.

Abstract
PURPOSE OF REVIEW To review the most recent advances and provide a description of the most common autoimmune diseases causing myelitis and selective spine disorders. The ultimate goal of this article is to facilitate the prompt recognition of these diseases. RECENT FINDINGS The recent discovery of biomarkers such as aquaporin 4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) antibodies has changed our understanding of autoimmune diseases affecting the spinal cord as well as their treatment and outcomes. Autoimmune neurology is an increasingly evolving field that encompasses a broad spectrum of autoimmune-inflammatory diseases of the central nervous system (CNS) and peripheral nervous system (PNS). Autoimmune disorders of the spinal cord are a heterogeneous group of myelopathies with a broad differential diagnosis and many of them have been recently identified. Prompt recognition of these myelopathies is important as some of them are treatable, which could improve patient outcomes and prevent disability.
