h pylori association with jra, allergies and overactive bladder

my son suffers from enviromental allergies and seems to have a corn and gluten sensitivity. He is being treated for a spasmic bladder and was recently diagnosed with jra. He is also anemic. The chiropracter kinesiologist we visited suspects h pylori and claims that my sons ailments are all associated to the h pylori infection. Sems odd and hard to believe its true since none of the medical doctors we saw in the past ever mentioned this. Whats your opinion on this whole thing? eagerly awaiting your reply
