Is there a correlation between antibiotic use and the severity or post-infection conditions of COVID-19 and other viral infections?

Antibiotics are one of the most frequently prescribed medications in modern medicine; besides treating bacterial infections, they may often be utilized for prophylactic purposes, including during select viral infections. It has been shown that 74.9% of COVID-19 patients received antibiotics as a part of their treatment regimen during the pandemic.

Nutritional Behavior in European Countries during COVID-19 Pandemic-A Review.

COVID-19 is highly linked with hyperinflammation and dysfunction of the immune cells. Studies have shown that adequate nutrition, a modifiable factor affecting immunity and limiting systemic inflammation, may play an adjunct role in combating the negative consequences of SARS-CoV-2 infection. Due to the global lockdown conditions, the COVID-19 pandemic has contributed, among others, to restrictions on fresh food availability and changes in lifestyle and eating behaviors.

Effect of obesity and hypothyroidism on hepcidin concentration in pregnancy - a pilot study using maternal and umbilical cord blood at delivery day.

Hepcidin is a primary regulator of iron metabolism in the human body. By promoting ferroportin degradation, hepcidin reduces intestinal iron absorption and its release from intracellular stores. In the course of pregnancy, gradually declining hepcidin concentrations encourage placental iron transfer, thereby providing the appropriate amount of iron for fetal development.

G6PD deficiency-does it alter the course of COVID-19 infections?

Despite the existence of well-founded data around the relationship between reactive oxygen species (ROS) and glucose-6-phosphate dehydrogenase (G6PD), current research around G6PD-deficient patients with viral infections, and limitations as a result of their condition, are inadequate. Here, we analyze existing data around immunological risks, complications, and consequences of this disease, particularly in relation to COVID-19 infections and treatment. The relationship between G6PD deficiency and elevated ROS leading to increased viral load suggests that these patients may confer heightened infectivity.
