ABSTRACT

Objective:

To investigate the effects of deafness capsule combined with vinpocetine injection on hearing function, hemorheology and T lymphocyte subsets in patients with sudden deafness.

Methods:

Eighty patients with sudden deafness who received treatment in Wenzhou Central Hospital from April 2017 to October 2019 were included in this study. They were randomly assigned to undergo treatment either with vinpocetine injection (control group, n = 40) or with deafness capsule combined with vinpocetine injection (observation group, n = 40) for 1 month. Efficacy, hearing function, hemorheology, T lymphocyte subsets and adverse reactions were compared between the control and observation groups.

Results:

Total response rate in the observation group was significantly higher than that in the control group [90.00% (36/40) vs. 67.50% (27/40), χ2 = 6.050, P = 0.014). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). After 1 month of treatment, plasma viscosity, high-shear whole blood viscosity, low-shear whole blood viscosity in the observation group were (1.21 ± 0.29) mPa·s, (2.41 ± 0.31) mPa·s, (5.25 ± 1.29) mPa·s respectively, which were significantly lower than those in the control group [(1.65 ± 0.22) mPa·s, (4.94 ± 0.36) mPa·s, (8.64 ± 1.32) mPa·s, t = 7.64, 33.68, 11.61, all P < 0.001). The percentages of CD 8+, CD 4+, and CD 4+/CD 8+ T lymphocyte subsets in the observation group were (24.28 ± 2.16)%, (46.05 ± 6.52)% and (1.90 ± 0.28) respectively, and they were (27.41 ± 2.09)%, (40.54 ± 5.48)%, (1.48 ± 0.24) respectively in the control group ( t = 6.58, 4.09, 7.20, all P < 0.001). Pure tone threshold in the observation group was significantly lower than that in the control group [(38.07 ± 4.82) dB vs. (51.97 ± 5.96) dB, t = 11.46, P < 0.001).

Conclusion:

Deafness capsule combined with vinpocetine injection is highly effective on sudden deafness. The combined therapy can improve the hearing function, hemorheology, and the immunological function of T lymphocyte subsets in patients with sudden deafness.
