Katie had + PA for 23 months. Last month, her culture was neg !! However, just wanted 2 let u know that I have continued the GSH (oral and inhaled) while Katie was on Cipro. I did my own "mom research study", Cipro and the inhaled TOBI with GSH and without...didn't make any difference for us. Then, we just stopped even doing the Cipro and just did the TOBi.If anything, in my opinion for Katie, I think the GSH helped the PA from getting worse. I don't know if the GSH would affect Cipro tx for the haemophilis, but I just wanted 2 let u know about our experience. Katie has cultured Haemophilis b4, but we've not specifically treated that. Good luck!
