Abstract

Background: Zinc – a trace element that plays an important role in many metabolic processes and it may influence the pathophysiology of seborrheic dermatitis. Currently, it is a fact that many patients with seborrheic dermatitis are given oral zinc therapy, however, is zinc really related to seborrheic dermatitis? Subjects and methods: This is a case-control study. From March 2021 to March 2022, patients with seborrheic dermatitis who came for examination and treatment at Ho Chi Minh city hospital of dermato-venereology that met the sample selection criteria. Results: After analyzing serum zinc levels in 46 patients with seborrheic dermatitis and 46 healthy people with similar age, sex and BMI, the serum zinc concentration of the disease group (84,31 ± 17,17 µg/dL) had no difference compared with the control group (88,63 ± 15,12 µg/dL)  with p = 0,21. Conclusion: The serum zinc concentration of patients with seborrheic dermatitis did not differ from that of healthy subjects. Therefore, it is not necessary to test serum zinc levels in patients with seborrheic dermatitis and zinc supplementation in these patients should also be reconsidered in order to reduce costs for patients.
