Mumbai: Avascular necrosis, or bone tissue death, can be a subsequent weakening condition among post-covid patients after the outbreak of mucorikosis or black fungi two months ago.
At least three cases of avascular necrosis confirmed after Covid-19 has been reported scientifically from Mumbai, and doctors are afraid more likely in the next few months.
The common factor between mucorikosis and avascular necrosis is the use of steroids, the only drug that is proven to help covid patients.
Hinduja Hindu Hospital, Mahim, treated three young patients (under 40) who developed necrosis two months after they were treated covid.
“They developed pain in their femur bones,” said Sanjay Agarwala, Medical Director of Hindu Hospital.
The research paper, ‘Avascular necrosis as part of Long Covid-19’, was published on Saturday in the BMJ case study.
Other orthopedic specialists told TII they had also seen one or two cases among post-covid patients.
His studies underlined two trends: Post-Covid patients have a lower steroid threshold dose and the emergence of previous presentations.
They were given an average dose of 758mg of corticosteroid prednisolone less than 2,000 mg of doses known to trigger AVN.
Second, it usually takes six months to one year to develop AVN after post-steroid use.
“But these patients developed the initial AVN at an average of 58 days after their diagnosis,” he said.
“Covid victims, who have used steroids, and then developed hip or thigh pain, need MRI confirmation to build AVN’s diagnosis of the hip,” he said.
