CD4 and hearing loss disorder: These findings are contrary to the findings of the studies such as Fokuou et al. [21] who found that CD4 cells did not have any influence on hearing function, but also on findings by Fasunla et al. [16], Obasineke et al., [17] and Van der Westhuizen et al. [10] who found participants with low CD4 cell count to be at a greater risk for hearing loss.
