Association between the 4G/5G polymorphism of plasminogen activator inhibitor-1 (PAI-1) gene and sudden sensorineural hearing loss in Caucasian population: a meta-analysis:

Abstract



Purpose

To clarify the association between the 4G/5G polymorphism of plasminogen activator inhibitor-1 (PAI-1) and sudden sensorineural hearing loss (SSNHL).




Methods

A systematic literature search of related studies up to August 30, 2019 in the PubMed and Embase databases was performed, and the results were displayed by odds ratios (ORs), and their 95% confidence intervals (CIs) were assessed using the STATA12.0 software using an allele model and a recessive model.




Results

Three eligible studies covering 519 subjects (241 cases, 278 controls) were identified. No statistically significant association was detected between the 4G/5G polymorphism and SSNHL in any model (allele model: 5G vs. 4G, OR = 0.952, 95% CI = 0.765–1.185, P = 0.662; recessive model: 5G/5G vs. 4G/5G + 4G/4G, OR = 0.841, 95% CI = 0.415–1.704, P = 0.631).




Conclusions

There is no statistically significant association between the 4G/5G polymorphism of PAI-1 gene and SSNHL in the Caucasian population, and well-designed studies covering more patients and institutions should be conducted.
