| خلاصه مقاله | Background and Aim: The coronavirus disease-2019 (COVID-19) pandemic, driven by the severe acute
respiratory syndrome coronavirus-2 (SARS-CoV-2) virus, has resulted in substantial global health
challenges. Identifying factors that influence the severity of COVID-19 is essential for enhancing patient
management and outcomes. Iron metabolism has emerged as a critical component in the pathophysiology
of COVID-19. Total Iron Binding Capacity (TIBC) serves as a vital marker of iron status, indicating the
capacity of transferrin to bind and transport iron. Variations in TIBC levels have been documented in
numerous infectious and inflammatory diseases, including COVID-19. Despite these observations, the
precise relationship between TIBC and COVID-19 severity remains inadequately explored. This study
aims to elucidate the correlation between TIBC levels and the severity of COVID-19, thereby
contributing to a deeper understanding of iron metabolism’s role in the progression of this disease.
Methods: We reviewed 300 articles about COVID-19, TIBC, and their relationships from November 1,
2020, to December 30, 2023. Based on relevance and quality, we selected 55 articles for detailed analysis.
Results: The findings demonstrate a consistent reduction in TIBC and serum transferrin levels among
COVID-19 patients. This reduction is frequently linked to elevated oxidative stress, which can
compromise cellular repair mechanisms and weaken immune responses. The findings also indicate that
oxidative stress significantly contributes to the severity of COVID-19. Therefore, reduced levels of TIBC
can increase the risk of severe COVID-19 in individuals. Furthermore, lower TIBC levels are often
associated with poorer health outcomes and increased mortality rates in patients.
Conclusion: The findings underscore the importance of monitoring TIBC levels as a potential marker for
predicting severe outcomes in COVID-19 patients. Additionally, it is important to maintain appropriate
TIBC levels as it could be crucial in enhancing patient prognosis, improving recovery rates, and
significantly reducing mortality rates among affected individuals. |
