Abstract
Vascular causes are most commonly associated with sudden sensorineural hearing loss (SSHL). This study was performed to determine the relationship between serum endothelin-1 (ET-1), high-density lipoprotein cholesterol (HDL-C), soluble vascular cell adhesion molecule-1 (sVCAM-1) levels, and the degree of hearing loss in patients with SSHL. Firstly, 60 SSHL patients were admitted to The First Hospital of Shanxi Medical University. In the same period, 60 healthy subjects matching the age and gender of SSHL patients were selected as the control group. Then, serum levels of ET-1, HDL-C, and sVCAM-1 were measured by enzyme-linked immunosorbent assay (ELISA). Next, the relationship between serum levels of ET-1, HDL-C, and sVCAM-1 with clinicopathological factors and their diagnostic and prognostic values were analyzed and evaluated. Serum ET-1 and sVCAM-1 were increased, and HDL-C was decreased in patients with SSHL. Serum ET-1 and sVCAM-1 were higher and HDL-C was lower in patients aged ≥ 45 years, or severe hearing loss patients (P < 0.05). ROC analysis determined that ET-1 (AUC = 0.839), HDL-C (AUC = 0.830), and sVCAM-1 (AUC = 0.865) had excellent diagnostic values. In addition, patients with low levels of ET-1 and sVCAM-1 and high levels of HDL-C had better hearing prognosis (P < 0.05). Abnormal serum ET-1, HDL-C, and sVCAM-1 in patients with SSHL are closely related to age, and degree of hearing loss, and perform diagnostic and prognostic values.

Shim YJ, Choi HG, Wee JH. Association between Chronic Kidney Disease and Sudden Sensorineural Hearing Loss: A Longitudinal Follow-Up Studies Using ICD-10 Codes in a National Health Screening Cohort. J Clin Med 2023; 12:jcm12082861. [PMID: 37109198 PMCID: PMC10145097 DOI: 10.3390/jcm12082861] [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: 03/22/2023] [Revised: 04/10/2023] [Accepted: 04/12/2023] [Indexed: 04/29/2023] Open
Abstract
This study aims to investigate the association between chronic kidney disease (CKD) and sudden sensorineural hearing loss (SSNHL) using a population-based cohort study. We used data from the Korean National Health Insurance Service-Health Screening Cohort. Participants were selected based on diagnosis and treatment codes, and CKD participants were 1:4 matched with control participants. Covariates, including demographic and lifestyle factors, and comorbidities were considered in the analysis. We calculated the incidence rate and hazards ratio of SSNHL. A total of 16,713 CKD participants and 66,852 matched controls were enrolled. The CKD group had a higher incidence rate of SSNHL compared to the control group at 2.16 and 1.74 per 1000 person-years, respectively. The CKD group exhibited a higher risk for SSNHL compared to the control group with adjusted HR 1.21. In the subgroup analysis, the presence of cardiovascular risk factors was associated with a diminished effect of CKD on the risk of developing SSNHL. This study provides strong evidence of an association between CKD per se and an increased risk of SSNHL even after adjusting for various demographic and comorbidity factors. The findings suggest that CKD patients may require more comprehensive monitoring for hearing loss.

Abstract
Background Previous evidence has indicated CMP-Neu5Ac hydroxylase (Cmah) disruption inducesaging-related hearing loss (AHL). However, its function mechanisms remain unclear. This study was to explore the mechanisms of AHL by using microarray analysis in the Cmah deficiency animal model. Methods Microarray dataset GSE70659 was available from the Gene Expression Omnibus database, including cochlear tissues from wild-type and Cmah-null C57BL/6J mice with old age (12 months, n = 3). Differentially expressed genes (DEGs) were identified using the Linear Models for Microarray data method and a protein–protein interaction (PPI) network was constructed using data from the Search Tool for the Retrieval of Interacting Genes database followed by module analysis. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis was performed using the Database for Annotation, Visualization and Integrated Discovery. The upstream miRNAs and potential small-molecule drugs were predicted by miRwalk2.0 and Connectivity Map, respectively. Results A total of 799 DEGs (449 upregulated and 350 downregulated) were identified. Upregulated DEGs were involved in Cell adhesion molecules (ICAM1, intercellular adhesion molecule 1) and tumor necrosis factor (TNF) signaling pathway (FOS, FBJ osteosarcoma oncogene; ICAM1), while downregulated DEGs participated in PPAR signaling pathway (PPARG, peroxisome proliferator-activated receptor gamma). A PPI network was constructed, in which FOS, ICAM1 and PPARG were ranked as hub genes and PPARG was a transcription factor to regulate other target genes (ICAM1, FOS). Function analysis of two significant modules further demonstrated PPAR signaling pathway was especially important. Furthermore, mmu-miR-130b-3p, mmu-miR-27a-3p, mmu-miR-27b-3p and mmu-miR-721 were predicted to regulate PPARG. Topiramate were speculated to be a potential small-molecule drug to reverse DEGs in AHL. Conclusions PPAR mediated signaling pathway may be an important mechanism for AHL. Downregulation of the above miRNAs and use of topiramate may be potential treatment strategies for ALH by upregulating PPARG.

Abstract
OBJECTIVES The aim of this study was to reveal the possible role of endothelial dysfunction in sensorineural hearing loss (SNHL) by determining the serum endocan levels of patients with varying degrees of SNHL. MATERIALS AND METHODS Patients with documented SNHL and healthy controls were included in the study, whereas those with a known history of chronic inflammatory condition were excluded. In addition, a recent history of use of glucocorticoids, nonsteroid anti-inflammatory drugs, or any ototoxic medications was also considered as an exclusion criterion due to its potential impact on endocan synthesis and metabolism. Following overnight fasting, blood samples were collected, and serum endocan levels were measured. For statistical analysis of the data, PASW Statistics for Windows version 18 was used. RESULTS The comparison of the subgroups yielded no statistically significant difference between the control and mild-to-moderate SNHL groups. Despite the increase in hearing loss, the difference between the endocan levels in these patients did not increase proportionately and was not statistically significant (p>0.05). The patients in the severe SNHL group had a higher level of serum endocan than those in other groups, and the difference was statistically significant (p<0.05). CONCLUSION The serum endocan levels failed to show a proportionate increase with increasing degree of SNHL, indicating that there is no precise association between SNHL and serum endocan levels. The serum endocan levels of patients with SNHL did not significantly differ from those of the healthy controls.

Abstract
The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating, and categorizing indications for the evidence-based use of therapeutic apheresis in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the Committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Seventh Edition of the JCA Special Issue continues to maintain this methodology and rigor to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Seventh Edition, like its predecessor, has consistently applied the category and grading system definitions in the fact sheets. The general layout and concept of a fact sheet that was used since the fourth edition has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis in a specific disease entity. The Seventh Edition discusses 87 fact sheets (14 new fact sheets since the Sixth Edition) for therapeutic apheresis diseases and medical conditions, with 179 indications, which are separately graded and categorized within the listed fact sheets. Several diseases that are Category IV which have been described in detail in previous editions and do not have significant new evidence since the last publication are summarized in a separate table. The Seventh Edition of the JCA Special Issue serves as a key resource that guides the utilization of therapeutic apheresis in the treatment of human disease. J. Clin.

Abstract
An endothelial dysfunction has been described in idiopathic sudden sensorineural hearing loss (ISSHL) patients. The purpose of our review was to: i) identify, evaluate and review recent research about cardiovascular risk factors involvement and signs of endothelial dysfunction in ISSHL; ii) implication of these discovering in clinical practice and future research. A Medline literature search was conducted to identify any study on the involvement of endothelial dysfunction in ISSHL, published in the English language in the last decade. The following MEDLINE search terms were used: sudden sensorineural hearing loss (SSHL) and endothelial dysfunction (text words). Additional studies were identified by hand searching the references of original articles and review articles. Studies were not excluded on the basis of the qualitative or quantitative definitions of SSHL, treatment regimens, or outcome measures. Data were extracted from included papers by a reviewer. Information on the patients, investigations, methods, interventions, and outcomes were systematically analyzed. Characteristics and results of all included studies were reviewed systematically. High levels of adhesion molecules, hyperhomocysteinemia and lower folate levels, unbalanced oxidative status, a lower value of flow-mediated dilatation of brachial artery and a reduced percentage of circulating endothelial progenitor cells in patients affected by ISSHL support the hypothesis that this syndrome should be considered as a microcirculation disorder based on endothelial dysfunction and drive clinicians to implement all the traditional strategies used for preventing cardiovascular events, to also reduce the likelihood of ISSHL occurrence.

Abstract
Objectives We used hearing tests and peripheral blood sample analyses to characterize the pathology of idiopathic sudden sensorineural hearing loss (ISSNHL) and to identify possible prognostic factors for predicting recovery of hearing loss. Study Design A retrospective, multicenter trial was conducted. Methods Two hundred three patients examined within 7 days after the onset of ISSNHL received prednisone with lipo-prostaglandin E1. Pure-tone auditory tests were performed before and after treatment with these drugs. Blood tests were performed on blood samples collected during the patients’ initial visit to our clinic. Results In all patients, elevated white blood cell (WBC) counts, fasting blood sugar levels, HgbA1c, and erythrocyte sedimentation rate (ESR) significantly correlated with high hearing threshold measurements obtained on the initial visit. High fibrinogen levels, WBC counts, ESR, and low concentrations of fibrinogen degradation products (FDP) were associated with lower hearing recovery rates. Additionally, different audiogram shapes correlated with different blood test factors, indicating that different pathologies were involved. Conclusions High fibrinogen levels measured within seven days after ISSNHL onset correlated with poorer hearing recovery. This may be a consequence of ischemia or infections in the inner ear. The high WBC counts also observed may therefore reflect an immune response to inner ear damage induced by ischemic changes or infections. Our data indicate that therapeutic strategies should be selected based on the timing of initial treatment relative to ISSNHL onset.

Abstract
We present results of the second survey of the Italian Multicenter Study on Low-Density Lipoprotein Apheresis (IMSLDLa-WG/2). The study involved 18 centers in 2009, treating 66 males and 35 females, mean age 47 ± 18 years. Mean age for initiation of drug treatment before low-density lipoprotein apheresis (LDLa) was 31 ± 18 years, mean age to the first LDLa was 37 ± 20 years and average duration of treatment was 9 ± 6 years. The techniques used included direct adsorption of lipids, dextran sulfate cellulose adsorption, heparin-mediated low-density lipoprotein (LDL) precipitation, cascade filtration, and plasma exchange. The mean treated plasma/blood volumes/session were 3127 ± 518 mL and 8666 ± 1384 mL, respectively. The average plasma volume substituted was 3500 ± 300 mL. Lipid therapy before LDLa included ezetimibe, statins, ω-3 fatty acids and fenofibrate. Baseline mean LDL cholesterol (LDLC) levels were 386 ± 223 mg/dL. The mean before/after apheresis LDLC level decreased by 67% from 250 ± 108 mg/dL (P = 0.05 vs. baseline) to 83 ± 37 mg/dL (P = 0.001 vs. before). Baseline mean Lipoprotein(a) [Lp(a)] level was 179 ± 136 mg/dL. Mean before/after apheresis Lp(a) level decreased by 71% from 133 ± 120 mg/dL (P = 0.05 vs. baseline) to 39 ± 44 mg/dL (P = 0.001 vs. before). Major and minor side effects occurred in 27 and 62 patients, respectively. Among patients with coronary artery disease (CAD), 62.3% had coronary angiography and 50.4% coronary revascularization before LDLa. Single vessel, double vessel and triple vessel CAD occurred in 19 (30.1%), 15 (23.8%) and 29 (46%) patients, respectively. Both CAD and extra-CAD occurred in 41.5%, 39% had hypertension, 9.9% were smokers, 9.9% consumed alcohol and 42% were physically active. Ischemic cardiovascular events were not observed in any patient over 9 ± 6 years of treatment. Two centers have also treated 34 patients (females: 17/males 17; no. sessions: 36; average plasma volume treated: 3000 mL) for sudden hearing loss (SHL). Relief of symptoms was obtained, independently of the system used (HELP; cascade-filtration).

Abstract
Double filtration plasmapheresis (DFPP) was applied to the treatment of two different categories from 100 cases that had been collected over a 5 year period (2007-2011). These categories were allocated into groups by size of toxic substances, which were classified as two different kinds of diseases. Group I comprised diseases that were caused by alloimmunity in transplantation, autoimmune diseases, complicated nephrotic syndrome, pure red cell aplasia, and toxemia of pregnancy. This group was treated with a plasma separator (plasmaflow-05, Asahi Kasei) and plasma fractionators, EC-20W. The second group, which included hyperviscosity syndrome, was treated by the same plasma separator, but with different plasma fractionators using EC-40W. This group included diabetes nephropathy, hyperlipidemia, peripheral arterial diseases, and neurosensory hearing loss. Both groups used 1.5 plasma volumes in each treatment for three sessions in two consecutive weeks. The result of treatment in group I showed that plasma immunoglobulin G (IgG) was decreased substantially by 66% in either transplant or lupus nephritis patients after the third session. In the second group, IgM, fibrinogen, and lipid markedly responded to the treatment. Two diabetes nephropathy patients showed stable renal function for more than 12 months. Peripheral arterial disease was shown to benefit from significantly decreasing fibrinogen and IgM, which resulted in clinical tissue oxygenation. Neither bleeding diathesis nor membrane anaphylaxis were reported from the treatment. In summary, apheresis patients were shown to benefit in hypersensitized and hyperviscosity syndrome.

Abstract
OBJECTIVE The underlying pathology of sudden sensorineural hearing loss (SSNHL) is still not completely understood. Inflammatory and vascular factors are part of the present discussion. The aim of this study was to learn more about the possible role of adhesion molecules and cytokines in patients with SSNHL. These molecules are thought to contribute to endothelial dysfunction. STUDY DESIGN Case-control study with planned data collection. SETTING Tertiary referral center. SUBJECTS AND METHODS Blood samples of 35 patients presenting with SSNHL of more than 30 dB in at least 3 contiguous frequencies were compared to a gender- and age-matched control group of normal-hearing subjects. Levels of the soluble adhesion molecules intercellular adhesion molecule (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), endothelial selectin (E-selectin), and concentration of interleukin 6 (IL-6), interleukin 8 (IL-8), and monocyte chemoattractant protein 1 (MCP-1) were measured using established enzyme-linked immunosorbent assays. These parameters as well as fibrinogen and lipid values were statistically analyzed. RESULTS Levels of soluble ICAM-1, VCAM-1, E-selectin, IL-6, IL-8, and MCP-1 were not significantly elevated in patients with SSNHL. The clinical chemistry and hematologic determinations showed no significant differences between patients and control subjects. CONCLUSION This study revealed no association concerning SSNHL and typical vascular risk factors such as lipids and fibrinogen. Soluble adhesion molecules were not elevated in the SSNHL group. The role of endothelial dysfunction represented by increased levels of soluble adhesion molecules in the pathogenesis of SSNHL remains unclear. Further studies are necessary to elucidate the vascular etiology of SSNHL.

Abstract
HYPOTHESIS The aim of the present study was to evaluate the concentration of soluble intercellular adhesion molecule 1 and soluble vascular cell adhesion molecule 1 in patients affected by sudden sensorineural hearing loss (SSHL). STUDY DESIGN Prospective study. SETTING Tertiary referral center. PATIENTS Patients affected by SSHL were evaluated. Inclusion criteria for this study were hearing loss of more than 30 dB hearing level affecting at least 3 contiguous frequencies, normal hearing on the contralateral ear, negative history of hearing loss or ear surgery in the affected ear, and magnetic resonance with gadolinium negative for VIII cranial nerve pathologic findings. INTERVENTION Circulating levels of soluble intercellular adhesion molecule 1 and soluble vascular cell adhesion molecule (VCAM) 1 were evaluated by means of enzyme-linked immunosorbent assay. MAIN OUTCOME MEASURES The levels of adhesion molecules in SSHL patients were compared with those of a control group. RESULTS Intercellular adhesion molecule 1 and VCAM-1 levels in sera of patients with SSHL were significantly higher than those of the matched control subjects (p < 0.001). Statistical analysis did not show significant differences between the 2 groups in terms of the known vascular risk factors such as total and fractionated cholesterol, triglycerides, fibrinogen, erythrocyte sedimentation rate smoking, and diabetes. CONCLUSION The results of this study show that in SSHL patients, there is an increased expression of circulating adhesion molecules confirming the existence of an endothelial dysfunction and supporting the vascular involvement in the pathogenesis of the disease. The identification of high levels of adhesion molecules and of the endothelial dysfunction open the way to selective pharmacologic treatments able to correct the activation of endothelial cells.
