New Research Sheds Light On Long Covid
Genetic research out of the Liggins Institute sheds light on how serious Covid-19 infections can activate other health conditions.
New genetic research
finds conditions including heart disease and Parkinson’s
could be activated by the most severe cases of Covid-19
infection.
The researchers from Waipapa Taumata Rau, the
University of Auckland examined publicly available genetic
data from 8,500 people who were hospitalised with Covid-19,
some of whom died. They used computational methods to
integrate the data with published research on genetic
interactions.
The study, led by doctoral student Rachel
Jaros, at the Liggins Institute, found the SARS-CoV-2 virus
could activate both scientifically known health conditions
such as cardiovascular disease and previously unknown health
conditions including Parkinson’s. These conditions are
likely to add to the burden of long Covid. See Nature: Scientific
Reports.
In some cases, the heart disease or
Parkinson’s may have been evident in the person before
their Covid-19 infection but, in other instances, the virus
may activate the conditions, says Professor Justin
O’Sullivan of the Liggins Institute.
For the first time
in this study, the scientists were able to map biological
pathways linking the risk of severe Covid-19 infection with
risk of certain health issues.
“While our analysis has
confirmed many of the known genetic risk factors for severe
or fatal Covid-19 infections, it also throws up new genetic
risk factors,” says Professor O’Sullivan of the Liggins
Institute.
“Of great concern is the genetic risk for
Parkinson’s. We know Parkinson’s went up dramatically in
the years following the 1918 Spanish flu pandemic,” he
says.
The genetic research published in Scientific
Reports is expected to assist health practitioners and
researchers develop therapies for long Covid.
“The
novelty of our study is that we have identified the
mechanism that underlies the genetic links between Covid-19
infection and the observed comorbidities,” says Rachel
Jaros.
“We hope our research will help alleviate the
burden of long Covid through shedding light on genetic
interactions and biological pathways involved in serious
cases,” Professor O’Sullivan says.
“If you target
these conditions, then you can therapeutically reduce the
impact of them going
forward.”
