Thanks for a very inspirational post above. I am a 74 year old man in Cape Town and was diagnosed with Idiopathic Pulmonary Fibrosis (IPF) about 2 years ago. Although your husband has UIP, the condition is similar to mine. My pulmonologist said that it is incurable but that the symptoms could be relieved to an extent by taking ACC 200 mg effervescent tablets (1 three times a day in water). These have helped but just before Xmas I was involved in a major motor accident in which the seat belt and airbag saved my life, but gave my thorax quite a knock. My breathing has rapidly got worse since then.
I was very interested in reading about the use of H2O2 (peroxide) and am going to try this, initially taking it as drops in water. I am seeing the doctor again soon, and will see what his reaction is, as he never mentioned this idea to me. I know the chemical process - essentially the hydrogen peroxide is unstable and produces molecular oxygen and water. It is the oxygen that helps with the condition. It is in a way the same as having oxygen from a cylinder. (It's also why H2O2 bleaches hair and materials).
As far as a cause is concerned, I believe I may have contracted IPF from the dust of cat litter (the clay type) having been cleaning the kitties' trays every day for the last 20 or so years!
Thanks again for the post - Phil
