Urgent warning to anyone who’s had Covid over damage that can last months after infection

PEOPLE who tested positive for Covid have been left with lasting liver damage long after infection, according to new research.

Experts in Boston, US discovered Covid-positive patients had a "statistically significant" higher liver stiffness than the rest of the population.

Liver stiffness could suggest long-term liver injury such as inflammation or fibrosis, the build-up of scar tissue in the liver, they said.

Healthier liver tissue diminishes over time causing the liver to stop functioning properly, and in severe cases progressive fibrosis can lead to liver cancer or failure.

Dr Firouzeh Heidari a Research Fellow at Massachusetts General Hospital, said their findings show damage caused by Covid persists for a long time.

She said: "Our study is part of emerging evidence that Covid-19 infection may lead to liver injury that lasts well after the acute illness.

"We don't yet know if elevated liver stiffness observed after Covid-19 infection will lead to adverse patient outcomes."

Researchers compared patients who had Covid with two control groups, and each received an ultrasound shear wave elastography.

This measures tissue stiffness caused by illness.

Covid-positive patients had a high median liver stiffness of 7.68 kPa, compared to 5.99 kPa stiffness in those who didn't have Covid.

The measurement of kPa (kilopascal) refers to one thousand times the unit of pressure and stress.

Patients were organised into one of three groups, based on whether they received elastography and whether they tested positive for Covid.

Covid participants received a positive PCR test at least 12 weeks before the exam.

There were 31 in the Covid group, and 50 in the control group who had the exam, but had only tested negative on PCR tests during the pandemic.
