Comparison of Serum and Dietary Selenium Levels in Participants with a Positive History of Recurrent Herpes Lesions and Healthy Individuals.

AIM: In this study, we aimed to compare the level of serum and dietary selenium in participants with a positive history of recurrent herpes labial lesions and healthy controls.

MATERIALS AND

METHODS

This cross-sectional study, conducted during 2020-2021, evaluated the selenium serum level of 40 participants with a positive history of recurrent herpes labial lesions who had referred to Motahhari Laboratory in Shiraz, compared with 38 healthy controls. The selenium level of the serum was assessed by an absorption device, Atomic Graphite Furnace Model FS-240-AAS, made by a US Company. Independent T-test was used to compare the selenium level of males and females. In order to assess the mean age value and gender distribution between the two evaluated groups, the independent T-test and chi-square test were used, respectively. The serum selenium level was compered between both control and test groups.

RESULTS

The level of serum selenium was not statistically correlated with its dietary level in group 1 (participants with recurrent herpes labialis, P value = 0.18) and group 2 (healthy controls, P value = 0.6). The serum selenium level was compared between groups 1 and 2, which was significantly higher in healthy controls (P value < 0.0001). In contrast, dietary selenium level was not significantly different between patients with a history of herpes labialis and healthy controls (P value = 0.48). The level of serum selenium was not statistically correlated with its dietary level in group 1 (P value = 0.18) and group 2 (P value = 0.6).

CONCLUSION

Patients with recurrent herpes labialis had lower serum selenium level as compared to the healthy controls.
