Milk is nice for bones, however joints are one other story for some folks, based on a brand new examine.
A pressure of micro organism generally present in milk and beef could also be a set off for creating rheumatoid arthritis (RA) in people who’re genetically in danger, based on researchers on the College of Central Florida.
The micro organism — mycobacterium avium subspecies paratuberculosis, or MAP — is present in about half the cows in america. The micro organism might be unfold to people by way of consumption of contaminated milk, beef and produce fertilized by cow manure.
The brand new UCF findings by infectious illness particular Saleh Naser and rheumatologist Shazi Bég, revealed within the journal Frontiers in Mobile and An infection Microbiology, are the primary to attach the dots between MAP and RA, an autoimmune illness that assaults joints, muscle mass, bones and organs and impacts 1.5 million US adults.
The analysis was impressed by — and builds upon — earlier work by Naser that linked MAP with the persistent inflammatory situation of the gastrointestinal tract Crohn’s illness.
“Right here you’ve gotten two inflammatory illnesses, one impacts the gut and the opposite impacts the joints, and each share the identical genetic defect and handled with the identical medication. Have they got a standard set off? That was the query we raised and got down to examine,” Naser mentioned.
“We don’t know the reason for rheumatoid arthritis, so we’re excited that now we have discovered this affiliation.”
Bég recruited 100 of her sufferers for the examine. Topics volunteered medical samples for testing. Of the sufferers with rheumatoid arthritis 78% had been discovered to have a mutation within the PTPN2/22 gene, the identical genetic mutation present in Crohn’s sufferers, and 40% of that quantity examined optimistic for MAP.
“We imagine that people born with this genetic mutation and who’re later uncovered to MAP by way of consuming contaminated milk or meat from contaminated cattle are at the next danger of creating rheumatoid arthritis,” Naser mentioned.
Researchers mentioned that additional examine is required.
“We don’t know the reason for rheumatoid arthritis, so we’re excited that now we have discovered this affiliation,” Bég mentioned. “However there’s nonetheless an extended option to go. We have to discover out why MAP is extra predominant in these sufferers — whether or not it is current as a result of they’ve RA, or whether or not it precipitated RA in these sufferers. If we discover that out, then we will goal remedy towards the MAP micro organism.”
