ST. LOUIS – Low testosterone ranges in males are linked to extra extreme instances of COVID-19,
in accordance with Saint Louis College College of Medication and Washington College College
of Medication researchers.
The examine, “Relationship of circulating sex hormones with inflammation and disease severity in
COVID-19,” printed on-line Might 25 in JAMA Community Open.
Sandeep Dhindsa, M.D., a SLUCare endocrinologist and the director of SLU’s Division of Endocrinology, Diabetes
and Metabolism, is first writer on the paper.
Abhinav Diwan, M.D., a heart specialist and professor of medication at Washington College, is the examine’s
The cohort examine checked out COVID-19 sufferers hospitalized at Barnes-Jewish Hospital
between March-Might 2020.
Within the examine, researchers measured a number of hormones in blood samples from 143 sufferers
(90 males and 62 girls) who got here to Barnes-Jewish Hospital with COVID-19 signs and
confirmed instances of the sickness.
The researchers measured hormone ranges within the hospitalized cohort at days 3, 7, 14
and 28, for so long as the sufferers remained hospitalized. Dhindsa mentioned 28 males and
14 girls remained hospitalized past day 14.
Along with testosterone, the investigators measured ranges of estradiol, a kind
of estrogen produced by the physique, and IGF-1, a development hormone.
“Crucial causal issue for low testosterone is prone to be extreme sickness,”
Dhindsa mentioned. “As well as, it’s doable the lads with low testosterone previous to
getting COVID usually tend to have low testosterone through the sickness as nicely.
Nevertheless, we couldn’t take a look at that speculation since we wouldn’t have pre-COVID samples
on these sufferers.”
Low testosterone will also be attributed to getting older, weight problems and diabetes.
Diwan and Dhindsa attended medical faculty collectively, however that is their first analysis
“We’ve mentioned collaboration on varied analysis themes, however that is our first
publication collectively,” Dhindsa mentioned. “This challenge was initiated quickly after the pandemic
began – my position was primarily based on my experience in intercourse hormones and medical research,
whereas Dr. Diwan’s position was primarily based on his experience in mobile signaling, entry to
samples at Wash U and his collaborations with different Wash U investigators.”
The findings recommend that low testosterone concentrations might play a task in worse
outcomes for males with COVID-19, however researchers stress the necessity for additional examine.
Dhindsa mentioned he sees this examine resulting in a number of future analysis questions, together with:
- In comparison with males with regular testosterone, are males with low testosterone extra possible
to get severely unwell once they contract COVID (or different respiratory sicknesses)?
- After acute sickness of COVID, will testosterone alternative assist in the restoration course of?
- Can we examine the paradox of low testosterone in serum however elevated intercourse hormone
signaling in immune cells in males?
