Effect of beta-blocking agents on the increased serum gastrin levels in hyperthyroidism

In a number of hyperthyroid patients the serum gastrin level exceeds the normal range. Administration of beta-blocking agents results in a decrease of the hypergastrinaemia. The fall in the serum gastrin levels is unrelated to the effect of beta-blocking agents on peripheral thyroxine metabolism, but is associated with a decline of the plasma cAMP levels. It is suggested that, though beta adrenergic sensitivity is one of the factors of hypergastrinaemia in hyperthyroidism, other factors may be involved in its production, too.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
