Criteria for PPF Diagnosis

PrevNext

0:00

So how do you define someone

0:02

with progressive pulmonary fibrosis?

0:04

They need to have two or the three criteria

0:06

within the last 12 months.

0:08

So either worsening respiratory symptoms, evidence

0:10

of physiological disease, progression

0:12

or radiological worsening.

0:14

So radiological. Worsening. What does that mean?

0:16

It's either the extent of traction Bronchi X

0:18

or fibrosis is getting worse

0:20

or new ground lass opacity with traction bronchiectasis.

0:23

There's frank areas of new

0:25

fine reticulation like representing early fibrosis,

0:29

or the reticulation that we're seeing

0:31

or the ground lass we're seeing is becoming more coarse.

0:33

There's like there's more reticulation superimposed on the

0:36

previous disease or new honeycombing.

0:38

We know honeycombing is certainly a concerning finding

0:41

for pulmonary fibrosis or increased low bar volume loss.

0:45

And so that's how we find it. Two outta these three things

0:47

can define someone with PP.
