Definitely no fun, but this does sound promising. Good luck to us all.
Seriously, I've tried pretty much everything (medical and alternative). And, actually, the saline rinses helped some, but didn't prevent the infection from re-emerging or clear it once it did.
Then, someone mentioned adding fresh garlic (steeped, like tea) to the saline rinse. Sounded nuts so I didn't bother for a year. Finally got fed up enough to try it and amazed to find that it works better than any medical treatment thus far. I'd recommend it, but it's a pain to prepare, smells, and is not a cure (i.e. you have to continue to do it regularly to keep the infection at bay).
That's why something like the subject post is hopeful.
You need to do an elimination diet, SCD diet, and eliminate all grains temporarily.
Curing this with antibiotics would only be a temporary solution, and antibiotics in general are not a good strategy for dealing with long term infections.
Because, some of my experience would suggest that it may be exacerbated by inflammation somewhat, but the primary cause is a persistent reservoir of bacteria. This could be a biofilm or otherwise dormant bacteria as described in the article. Actually, the latter is much more plausible as and, in all the time I have been dealing with this, no physician has ever mentioned that bacteria even have such a dormant state.
