Context:
COVID-19 is more than a respiratory infection, with deep implications regarding multiple systems and organs. Thyroid damage is frequent in COVID-19 and may overlap previous HCV or HCC associated diseases.
Objective:
The objective of this study is to determine the effects of COVID-19 in patients with HCV associated HCC and thyroid comorbidities.
Design:
We performed a retrospective study of the thyroid function tests and autoantibodies in patients with HCV-associated HCC prior and during COVID-19.
Subjects And Methods:
We included 52 consecutive patients with HCV-associated HCC and documented thyroid disease, diagnosed with COVID -19 between April and October 2020. Serum values of thyroid-stimulating hormone, free T3, free T4, anti-thyroglobulin antibodies and anti-thyroid peroxydase antibodies were determined and compared to baseline levels.
Results:
At baseline, 44 patients had positive antithyroid antibodies, 6 had hypothyroidism in substitution and 2 had hyperthyroidism under treatment. During COVID-19 we found an increase in serum values of antithyroid antibodies, and decreased levels of TSH, freeT3 and freeT4 levels. Specific therapies were discontinued in one patient with hyperthyroidism and 3 patients with hypothyroidism.
Conclusion:
There is a significant impact of COVID-19 on the thyroid homeostasis; a long-term prognostic value for patients with HCC infected with COVID-19 required further extensive research.

Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
