Hi everyone. I am currently dealing with what I believe is LPR. It has been diagnosed as such by an ENT, on transnasal endoscopy, who has seen throat/vocal chord inflammation both times. I also have symptoms such as sore throat, tight throat, bitter taste in throat/mouth, and burning tongue. My main symptom of throat tightness has been helped about 90% by using PPIs, however I continue to have this annoying bitter taste and frequently a sore throat and tongue issues.

I had a 24 hr PH/impedance monitoring test done in January, and had a "normal" demeester score, and sour/bitter taste was associated with weakly acidic reflux. In the summary of the results of the test, there was no mention of proximal (near throat) acid exposure, only distal exposure which is near the lower esophageal sphincter.

So I am curious, if anyone here has had their LPR confirmed via 24 hour PH monitoring. Or maybe who has LPR that had a seemingly "normal" 24 hour study? If you did have 24 hour monitoring, do you know if they used a separate sensor positioned in the larynx area?

Thanks.

Drtinsac, just a suggestion. Go to www.restech-corp.com/ and read about the Dx-pH test to determine amount of acid reaching the airway. This is used to detect airway reflux . The company was very helpful providing a name and phone number of a physician that has the machine in my area. Then call the office to confirm that they actually have it and we found that they were knowledgeable about LPR too. The test might answer your questions --this might answer the proximal acid exposure. Sure hopes this can help. BUMPER

Thanks Pat - I have read of the Restech. Never thought about asking them who has their stuff nearby, I will check with them next week. I would hope UC Davis has it, where I am being seen, we'll see. The 24 hr test they gave me was with a single catheter, which I believe is not sensitive for LPR.

This is a very informative article about LPR. It opened our eyes and gave a better understanding to our problem. Hope it helps. Did you call Restech and did UC Davis have The Dx Machine. Bumper!

Interesting article, thanks Pat.

I finally got around to calling Restech, and UC Davis ENT does not have one. However they said the Veterinary school has one (weird!).

They told me that 'Sacramento ENT' has the DX PH probe. I'm not sure how I'd get to use it without having to pay out of pocket, I might have to be referred there or something. I see UC Davis ENT in another 2 months, so I can inquire then.
