Objective To explore the value of serum aquaporin 8 (AQP8)
expression in evaluating the degree of hydrolabyrinth and predicting
prognosis in patients with Meniere’s disease. Methods 105 patients with
Meniere’s disease in our hospital were included in the Meniere’s disease
group.Another 102 healthy subjects in our hospital were included as the
control group. The multivariate Logistic regression was used to analyze
the influencing factors of poor prognosis in patients with Meniere’s
disease. Results The expression of serum AQP8 mRNA in the Meniere’s
disease group was greatly higher than that in the control group
(P<0.05). Serum AQP8 mRNA expression in severe hydrops group
was greatly higher than that in mild hydrops group and no endolymphatic
hydrops group, and serum AQP8 mRNA expression in mild hydrops group was
greatly higher than that in no endolymphatic hydrops group
(P<0.05). The course of disease, the proportion of severe
hydrops and the expression of serum AQP8 mRNA in the poor prognosis
group were greatly higher than those in the good prognosis group
(P<0.05). The area under the curve (AUC) of serum AQP8 mRNA
for predicting poor prognosis in Meniere’s disease patients was 0.812
(95%CI: 0.702-0.922), with a sensitivity of 81.0% and a specificity of
70.2%. AQP8 mRNA was an independent risk factor for poor prognosis in
patients with Meniere’s disease (P<0.05). Conclusion AQP8 mRNA
is associated with the degree of hydrolabyrinth in patients with
Meniere’s disease, and has a high performance in predicting prognosis.
