Requena, Teresa / Gazquez, Irene / Moreno, Antonia / Batuecas, Angel / Aran, Ismael / Soto-Varela, Andres / Santos-Perez, Sofia / Perez, Nicolas / Perez-Garrigues, Herminio / Lopez-Nevot, Alicia / Martin, Eduardo / Sanz, Ricardo / Perez, Paz / Trinidad, Gabriel / Alarcon-Riquelme, Marta E / Teggi, Roberto / Zagato, Laura / Lopez-Nevot, Miguel A / Lopez-Escamez, Jose A. ·Human DNA Variability Department, Centro de Genómica e Investigación Oncológica, Pfizer/Universidad de Granada/Junta de Andalucía (GENYO), Granada, Spain. ·Immunogenetics · Pubmed #23370977.

ABSTRACT: Toll-like receptors trigger the innate immune response by activating various cell types such us macrophages and lymphocytes. We genotyped SNV of TLR3, TRL7, TLR8 and TLR10 in 863 Spanish and 150 Italian patients with Meniere's disease (MD) and 1,013 controls by using Taqman assays. Real-Time qPCR was used to measure the expression level of TLR10 in peripheral blood leukocytes. The overall dataset showed that the C allele and the CC genotype of rs11096955 in TLR10 gene were more commonly observed in controls than patients (corrected p = 1 × 10(-3), OR = 0.68 [95 % confidence interval, 0.54-0.84] for CC genotype; corrected p = 1.5 × 10(-5), OR = 0.75 [0.66-0.85] for allele C). Moreover, the CC genotype was more frequent in patients with uni- (19 %) than bilateral sensorineural hearing loss (SNHL) (13 %). Logistic regression demonstrated that the time since the onset of MD, Tumarkin crises, hearing stage and rs11096955 were independent factors influencing the risk of bilateral SNHL. In addition, rs11096955 influenced hearing loss progression in patients with bilateral MD. No change in expression of TLR10 was observed according to CC, CA or AA genotypes. Our data suggest that allelic variants of TLR10 gene may influence the susceptibility and time-course of hearing loss of MD in the European population.

ABSTRACT: Variability in acute immune response genes could determine susceptibility or prognosis for Ménière's disease (MD). The cytokines tumor necrosis factor α (TNFα), macrophage migration inhibitory factor (MIF) and interferon γ (INFγ) are proinflammatory cytokines of the innate immune response. These cytokines mediate inflammation and have been previously associated with the inflammatory process in several autoimmune diseases. We investigated the association between functional allelic variants of MIF (rs35688089), IFNG (rs2234688) and TNFA (rs1800629) in patients with MD. In addition to testing these variants for an association with disease, we also tested for an association with clinical aspects of disease progression, such as persistence of vertigo and the sensorineural hearing loss. A total of 580 patients with diagnosis of definite MD, according to the diagnostic scale of the American Academy of Otolaryngology-Head and Neck Surgery, and 552 healthy controls were included. DNA samples from a set of 291 American patients were used to confirm the results obtained in the MIF gene in our Spanish cohort. Although we found a significant association with the allele containing five repeats of CATT within the MIF gene in patients with MD in the Spanish cohort [corrected p = 0.008, OR = 0.69 (95 % CI, 0.54-0.88)], this finding could not be replicated in the American set. Moreover, no genetic associations for variants in either the TNFA or IFNG genes and MD were found. These results support the conclusion that functional variants of MIF, INFG, and TFNA genes are not associated with disease susceptibility or hearing loss progression in patients with MD.

3 Article MICA-STR A.4 is associated with slower hearing loss progression in patients with Ménière's disease. 2012

ABSTRACT: HYPOTHESIS: Immune response may influence hearing outcome in Ménière's disease (MD). BACKGROUND: Major histocompatibility complex class I chain-related A (MICA) encodes a highly polymorphic stress-inducible protein, which interacts with NKGD2 receptor on the surface of NK, γδ T cells and T CD8 lymphocytes. We investigated the association of MICA gene with hearing outcome in MD and its linkage disequilibrium (LD) with human leukocyte antigen (HLA)-B. METHODS: MICA short tandem repeat polymorphism (MICA-STR) was genotyped using a polymerase chain reaction-based method in a total of 302 Spanish patients with MD and 420 healthy controls. Genotyping of HLA-B was performed using polymerase chain reaction and detected with reverse sequence-specific oligonucleotide probe system in 292 patients and 1,014 controls. RESULTS: Hearing loss was associated with the duration of MD (p = 0.001). We found that MICA*A5 alelle was significantly associated in the Mediterranean set (Pc = 0.04, odds ratio = 0.51 [95% confidence interval, 0.30-0.84]), but this finding was not replicated in the Galicia population. However, median time to develop hearing loss greater than 40 dB was 16 years (95% confidence interval, 9-23) for patients with the MICA*A.4 allele and 10 years (95% confidence interval, 9-11) for patients with another MICA-STR allele (log-rank test, p = 0.0038). We did not find statistical differences in the distribution of B locus between the MD and the control group. In the LD analysis, MICA*A5.1-HLA-B*07 (8.8%), MICA*A6-HLA-B*44 (8.3%), and MICA*A6-HLA-B*51 (8.3%) were the most common haplotypes, and the stronger LD was found for haplotypes MICA*A.4-HLA-B*18 (r2 = 0.41) and MICA*A.4-HLA-B*27(r2 = 0.29). CONCLUSION: The allelic variant MICA*A.4 is significantly associated with slower progression of hearing loss in patients with MD. This suggests that the immune response influence hearing level in MD.

4 Article Functional variants in NOS1 and NOS2A are not associated with progressive hearing loss in Ménière's disease in a European Caucasian population. 2011

Gazquez, Irene / Lopez-Escamez, Jose A / Moreno, Antonia / Campbell, Colleen A / Meyer, Nicole C / Carey, John P / Minor, Lloyd B / Gantz, Bruce J / Hansen, Marlan R / Della Santina, Charles C / Aran, Ismael / Soto-Varela, Andres / Santos, Sofia / Batuecas, Angel / Perez-Garrigues, Herminio / Lopez-Nevot, Alicia / Smith, Richard J H / Lopez-Nevot, Miguel A. ·Otology and Neurotology Group CTS495, GENYO, Centro de Genómica e Investigación Oncológica-Pfizer, Universidad de Granada, Junta de Andalucía, Granada, Spain. ·DNA Cell Biol · Pubmed #21612410.

ABSTRACT: Hearing loss in Ménière's disease (MD) is associated with loss of spiral ganglion neurons and hair cells. In a guinea pig model of endolymphatic hydrops, nitric oxide synthases (NOS) and oxidative stress mediate loss of spiral ganglion neurons. To test the hypothesis that functional variants of NOS1 and NOS2A are associated with MD, we genotyped three functional variants of NOS1 (rs41279104, rs2682826, and a cytosine-adenosine microsatellite repeat in exon 1f) and the CCTTT repeat in the promoter of NOS2A gene (rs3833912) in two independent MD sets (273 patients in total) and 550 controls. A third cohort of American patients was genotyped as replication cohort for the CCTTT repeat. Neither allele nor genotype frequencies of rs41279104 and rs2682826 were associated with MD, although longer alleles of the cytosine-adenosine microsatellite repeat were marginally significant (corrected p = 0.05) in the Mediterranean cohort but not in a second Galicia cohort. Shorter numbers of the CCTTT repeat in NOS2A were significantly more frequent in Galicia controls (OR = 0.37 [CI, 0.18-0.76], corrected p = 0.04), but this finding could not be replicated in Mediterranean or American case-control populations. Meta-analysis did not support an association between CCTTT repeats and risk for MD. Severe hearing loss (>75 dB) was also not associated with any functional variants studied. Functional variants of NOS1 and NOS2A do not confer susceptibility for MD.
