Effects of anxiety and depression symptoms on oxidative stress in patients with alopecia areata.

INTRODUCTION

Increased oxidative stress (OXS) and a high prevalence of psychiatric disorders are seen in alopecia areata (AA). However, OXS and psychiatric disorders have been studied separately in AA patients.

AIM: To determine the effects of anxiety and depression symptoms on OXS in AA patients.

MATERIAL AND

METHODS

The anxiety and depression levels of 33 AA patients and 33 normal controls (NC) were determined using the Hospital Anxiety and Depression Scale. The oxidative stress index (OSI) was calculated by measuring serum total antioxidant status (TAS) and total oxidant status (TOS) levels in AA patients and NC.

RESULTS

The AA patients had higher anxiety and depression scores than NC (p < 0.001 for both). Total oxidant status (p = 0.002) and OSI (p < 0.001) values were higher, and TAS (p < 0.001) levels were lower, in patients with AA compared to NC. However, patients' anxiety and depression scores were not correlated with the TAS, TOS, or OSI values (p > 0.05). There was no significant difference in TAS, TOS, or OSI values between patients with high and low anxiety or depression scores (p > 0.05).

CONCLUSIONS

These results show that OXS, anxiety, and depression scores were higher in patients with AA compared to NC. However, anxiety and depression scores were not associated with OXS in AA patients. More extensive studies should be performed to investigate the relationship between psychological status and OXS in patients with AA.
