Chronic Hypersensitivity Pneumonitis?

Saw a Professor who is an expert in lung disease today and she told me that Birmingham was wrong in telling me I have IPF.. Looking at my lung biopsy results together with CT scan shows I have an auto-immune disease. Had a load of blood tests to try and isolate which one. They want to treat it with low dose chemo (cyclophosphamide) and steroids. Have others experienced this?

I don't have this, but wonder if CHP could be the result of the IPF diagnosis, CHP in UK sounds like EAA (Extrinsic Allergic Alveolitis) but to be sure you would have to check back with your specialising consultant about these things.

A CT Scan show actual damage to lung tissue, so if this is the case, it would make sense you are having difficulty breathing.

Patient UK refer EAA - Synonym: hypersensitivity pneumonitis

BLF have a page on EAA also.

I hope you get on ok with the chemo (cyclophosphamide) drug and that it helps improve things for you.

Hope you are soon feeling much better.

Best wishes BC

My diagnosis is chp and has successfully been treated with steroids to date. My consultant has told me that their are other options before transplant open to us. I think that includes cyclophosphamide. Hope you are as successful as me.
