New York, May 9 : Men with a common form of hormone-sensitive hair loss are more prone to being hospitalised and at risk for ICU admission due to Covid-19, researchers have found.
Androgenetic alopecia is a condition of permanent hair loss from the scalp, causing baldness.
The study, led by researchers at US-based biotechnology company Applied Biology, found association between the androgen receptor (AR) gene and Covid-19.
Among men hospitalised with Covid, 79 per cent had androgenetic alopecia compared to 31-53 per cent that would be expected in a similar aged match population, the results showed.
The study involved 65 men who had been hospitalized with COVID-19. The researchers looked at the length of the polyglutamine repeat (or CAG repeat) region in the AR gene, which is linked to male-pattern baldness, in the men.
They found that the men whose AR CAG repeat was shorter than 22 nucleotides, or DNA molecules, were much less likely to end up in intensive care with COVID-19 than those whose CAG count was 22 or higher.
“Our data show that longer AR CAG scores are associated with more severe COVID-19 disease and indicate that AR CAG repeat length could be used as a biomarker to help identify male COVID-19 patients most at risk for ICU admissions,” said Andy Goren, chief medical officer of Applied Biology Inc. in Irvine, California.
Bald men are twice as likely to suffer severe Covid, experts warn

BALD men are up to twice as likely to suffer severe Covid, experts have warned.
New research suggests they spend up to twice as long in hospital with Covid than those who still have a full head of hair.

They are also admitted to intensive care in higher numbers.
Scientists say men’s Covid vulnerability largely comes down to male sex hormones called androgens.
