Abstract
Objective: Thiol-disulphide homeostasis (TDH) has a critical role in various clinical disorders. We aimed to assess the association of TDH with acute tonsillopharyngitis (AT) in children.
Methods: This study included 94 (73 viral and 21 bacterial) tonsillopharyngitis patients and 88 control children. Their native thiol, total thiol, and disulphide levels were measured.
Results: Viral and bacterial tonsillopharyngitis patients had lower native thiol levels compared with healthy children (P < 0.001 and P = 0.008, respectively). Both groups had lower total thiol levels compared with control children (P = 0.002 for viral, P = 0.011 for bacterial). The disulphide levels were lower in bacterial than in viral tonsillopharyngitis patients (P = 0.04), and there was a significant difference between viral tonsillopharyngitis patients and the control group (P < 0.001). The native/total thiol ratio in each patient group was lower than in the control group (P < 0.001 for viral, P = 0.017 for bacterial). The disulphide/native thiol and disulphide/total thiol ratios were significantly higher in viral (P < 0.001 for both) and bacterial tonsillopharyngitis patients (P = 0.017 for both) than in healthy children. In all patients, a correlation was found between the levels of C-reactive protein (CRP) and native thiol (r = −0.211, P = 0.04), CRP and total thiol (r = −0.217, P = 0.036), white blood cell (WBC) and native thiol (r = −0.228, P = 0.002), WBC and total thiol (r = −0.191, P = 0.01), and WBC and disulphide (r = 0.160, P = 0.03).
Discussion: TDH is altered in AT in children. The alteration is more prominent in viral than in bacterial tonsillopharyngitis.
