Antioxidant and inflammatory biomarkers in herpes zoster

Abstract

The risk of herpes zoster (HZ) increases as cell-mediated immunity declines with age.Even though oxidative stress plays a crucial role in the development of HZ, there are few serum biomarkers of the disease's antioxidant activity. The purpose of this study is to investigate the blood levels of major antioxidants in HZ patients. To the best of our knowledge, this is the first study on this issue in the literature. The serum levels of antioxidants including uric acid (UA), total bilirubin (TBİL), albumin (ALB), vitamin D levels, and inflammatory markers such as homocysteine (Hcy) and C-reactive protein (CRP) was retrospectively analyzed in 53 patients with HZ and 53 age-and sex-matched healthy controls (HCs). The relationships between these markers and postherpetic neuralgia (PHN) and the clinical severity of HZ were also evaluated.Serum levels of UA, TBIL, and ALB in patients with HZ were significantly lower than those in the HCs (p < 0.001), while no statistical differences were found in vitamin D levels between the groups. Hcy and CRP levels were significantly increased in HZ patients compared to HCs. Significant differences were observed in the serum levels of UA, Hcy, CRP, and vitamin D in the PHN group versus the non-PHN group (p < 0.001). The presence of inflammatory markers was found to be positively related to disease activity. Furthermore, when compared to the mild or moderate clinical types of HZ, these biomarkers were statistically significant in the severe clinical type.These results suggest that uncontrolled varicella-zoster virus reactivation, acute nerve damage, and PHN may all be associated with low antioxidant levels. These biomarkers may be a protective factor for HZ, but more research is needed to clarify the underlying mechanism.

Serum uric acid and triglycerides in clear cell renal cell carcinoma: A restrospective cross-sectional study

“…Moreover, SUA's multifaceted physiological effects, such as antioxidant effects and mediation of autoimmune diseases, are indicative of the crucial role it could play in the human body. [26,27] However, the study by Ghamri RA et al [23] reported no significant association between Table 3 Relationship between SUA (100μmol/L) and TGs (mmol/L) in diferent models.…”

Neutrophil Extracellular Traps and Their Possible Implications in Ocular Herpes Infection

“…Our implication is that most of the NETosis targeted inhibitors will show their potential effectiveness against ocular herpetic infection as well. For instance, the NADPH- and/or ROS-inhibiting pharmacological compounds such as diphenyleneiodonium chloride (DPI) and N -acetylcysteine (NAC) suppress NETosis, and many reports suggest reduction in ocular herpes infection when treated with antioxidants because it has been reported that HSV infection may be exacerbated by a cellular state of oxidative stress, while augmented intake of antioxidants might avert replication of the virus [ 100 , 101 , 102 , 103 , 104 ]. Furthermore, ROS inhibit NF-kB (Nuclear Factor kappa-light-chain-enhancer of activated B cells) translocation, which is a known marker for aggravated ocular HSV-1 infection [ 105 ].…”

Risk Factors for Poor Pain Control in Zoster-Associated Pain: A Retrospective Study

“…The results suggested that patients with chronic HZ pain were more likely to have poor pain control than those with acute HZ pain, which might be related to central sensitization. In addition, ALB Subacute phase vs acute phase c Chronic phase vs acute phase *Statistical significance levels in the poor control group were low, which might be related to deficits in nutritional status, weak physical condition, and low immunity [32].…”
