Even penetrates 'fat'. Scientists have proven increased mortality risks in obese people with COVID

The ability of the virus to infect adipose tissue may explain why obesity increases the risk of severe disease.

Obesity is an established independent risk factor for SARS-CoV-2 infection, as well as for disease progression after infection to death. Possible causes range from impaired breathing from the pressure of being overweight to altered immune responses in obese people, writes Stanford.

A new study from the Stanford School of Medicine gives a simpler reason: SARS-CoV-2 can directly infect adipose tissue. This, in turn, triggers the cycle of virus reproduction in the fat cells and causes marked inflammation in the immune cells located in the fat tissue. Inflammation affects even non-infected cells.

The researchers observed this in adipose tissue excised from patients undergoing stomach and heart surgery and then infected in the laboratory with SARS-CoV-2. They confirmed their findings in autopsy samples from deceased COVID-19 patients.

Adipose tissue surrounds our heart, intestines, kidneys, and pancreas, which can be adversely affected by inflammation. Surprisingly, the scientists found an infection capable of causing inflammation in virtually every SARS-CoV-2-infected adipose tissue sample they collected and analyzed.

“It is reasonable to assume that the presence of large amounts of infected fat may contribute to general inflammatory profile of critically ill COVID-19 patients,” said Katherine Blish, MD, Professor of Infectious Diseases, co-author of Scientific Translational Medicine.”

It may also contribute to persistent post-infection symptoms, collectively referred to as prolonged COVID . This hypothesis is being explored by Blish and another study co-author, Tracey McLaughlin, MD, Professor of Endocrinology and Infectious Diseases.
