BACKGROUND: An elevation in serum ferritin levels through an unknown mechanism was observed in COVID-19 infected patients. This study examined the association between patients' HLA genotype and serum ferritin level modulation and also assessed the effect of serum ferritin levels on infection severity/mortality. MATERIALS AND METHODS: One hundred and thirty-six COVID-19 Saudi patients were divided into two groups according to their ferritin levels: group 1 (<500 ng/mL, N = 67) and group 2 (>500 ng/mL, N = 69). HLA genotyping (class I and II) was carried out through the rPCR-SSO method. RESULTS: High serum ferritin levels were associated with a significant increase in infection severity, as 75% of ICU patients showed high levels of ferritin compared to 43% of patients with moderate symptoms, p = .002. This elevation indicated a gender skew in that 56% of the infected male patients displayed high ferritin levels compared to 36.6% of the female patients, p = .03. In terms of mortality, 74% of patients with fatal outcomes had a high level of serum ferritin compared to 47% of recovered patients, p = .039. There was a significant difference in the HLA frequency between the two groups, with a predominance of HLA-A*01 in the low-ferritin group (19.4 vs. 6.5%, p = .002, p(c) = .016) and predominance of C*03 in the high ferritin group (10.9 vs. 3%, p = .047, p(c) = .27). CONCLUSION: High serum ferritin levels are associated with an increase in COVID-19 severity, which may be affected by HLA polymorphism.
