Objective: To investigate the association between genetic polymorphisms and sudden sensorineural hearing loss (SSNHL). Most of the SSNHL cases still remain idiopathic, and several etiopathogenetic hypotheses, including a genetic predisposition, have been proposed. Methods: A literature review was conducted using different databases: Medline/PubMed, EMBASE, and CINAHL, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All databases have been searched from May 2016 to April 2020. Results: Genetic susceptibility could represent a key element in the pathogenesis of SSNHL. A number of genetic polymorphisms related to (1) inner ear microvascular disease and endothelial dysfunction and (2) to inner ear oxidative stress and inflammation have been addressed in the current literature. Conclusions: The potential identification of a genetic profile related to SSNHL could provide a more accurate prognostic evidence of idiopathic SSNHL (ISSNHL), offering to the patients not only early-prevention strategies but eventually information on various inheritance modalities.

Abstract Objective Waldenström’s macroglobulinemia (WM) is a rare indolent B-cell lymphoproliferative disorder, representing 1 to 2% of all hematological malignancies. Involvement of the inner ear is rare with only case reports published over the past six decades. Methods The occurrence of bilateral sudden sensorineural hearing loss is exceeding rare, with limited published data in the literature. We present a case of a 62-year-old man diagnosed with WM who presented with bilateral sequential sudden sensorineural hearing loss. Results A few months following his WM diagnosis, he experienced sudden hearing loss in his left ear. He was treated with a course of oral steroids with no improvement. Three months following this incident, he experienced a similar sudden loss of hearing in his right ear. Treatment for WM was initiated. A repeat hearing test, done 1 week later, did not show any significant improvement in his right hearing. Conclusion The clinical course of WM is highly variable, with relatively infrequent involvement of lymph nodes, spleen, or liver. The inner ear is rarely involved. In this article, otologic clinical presentation is discussed, along with a review of the literature on hearing loss in WM.

In this study, we investigated the role of MAP kinase phosphatase-1 (MKP-1) and rosiglitazone (RSG) in glucocorticoid resistance and glucocorticoid sensitivity, respectively, using a guinea pig model of lipopolysaccharide- (LPS-) induced sudden sensorineural hearing loss (SSHL). The pigs were divided into control, LPS, LPS+dexamethasone (DEX), LPS+RSG, and LPS+DEX+RSG groups. Their hearing was screened by auditory brainstem response measurement. Immunofluorescence staining was used to identify the location of MKP-1 in the inner ear. The expression levels of MKP-1 and the related proteins in the inner ear were detected using western blotting. The morphological changes in the cochlea were observed via hematoxylin-eosin staining. Severe hearing loss was observed in the LPS group, as opposed to the protection from hearing loss observed in the LPS+DEX+RSG group. A positive correlation was observed between MKP-1 expression levels and protection from hearing loss. RSG and DEX synergistically influenced inner ear inflammation. In conclusion, resistance of LPS-induced SSHL guinea pig models to glucocorticoids may result from impaired MKP-1 function in inner ear tissues, induced by glucocorticoids, impairing the inhibition of inflammation. Our findings present novel targets to develop potential therapeutics to treat inflammatory diseases of the inner ear.
