How many people with idiopathic pulmonary fibrosis are on lipitor (or related anti-cholesterol?

Haven't heard that before, but that doesn't mean anything at all. My cholesterol has always been a low number, not that I deserve it from what I eat - genetics. I was diagnosed 6 years ago and the disease was confirmed by open biopsy. I'm on 3L. of oxygen, take 10-15mg prednisone and it works for me. It started with a weird pneumonia and I haven't been too bad, really. When I get an URI, my doctors medicate me ASAP and I end up needing to take the antibiotic 2X longer than is recommended for normal people. But so far, so good. I can't tell if I'm deteriorating now or just out of shape and need some therapy, but I don't seem to have as much energy as I used to. I'm 62.
Last visit to the doctor included bloodwork to detect any signs of autoimmune disease. I'll keep you posted.
