<div class="FTQUOTE"><begin quote>I don't doubt he may have some asthma but the lung junk and tight chest does not seem typical of asthma. He does not wheeze and does not have "attacks." I know there are lots of manifestations of asthma but we have had to be convinced of this dx for years because he does not show signs of that, he shows signs of congestion. And, inhalers do not have the same immediate impact as they seem to with classic asthma. In fact, they do help clear him out, which is great, but they don't make him feel better. What confuses me as well is that Mayo says atelectasis can be caused by "severe asthma" which we have never seen in Owen.</end quote></div>
Here is our asthma experience, for what it's worth:
My son (symptomatic cf carrier) and my daughter (cf) both have issues here. My son has a dx of asthma, and my daughter has a pretty severe inflammation/asthma component to her cf, and both present very differently.
Shawn: When we were establishing his asthma action plan, he used a peak flow meter twice daily for a couple months. He very consistently blows the same numbers when he is well (300-330L/min). He has occasional episodes where he can feel some tightening and his numbers are nearly ALWAYS about 270L, and then more rare acute attacks complete with pain, wheezing and severe coughing, and his numbers drop as low as 220L. Using his Ventolin, or when really bad, nebbing albuterol, will bring his numbers up within minutes and provide pretty quick relief. His attacks are acute, consistent, and he feels the relief when we treat them. There is no sputum. He also had improvement in his endurance and attacks were greatly improved when he started daily Singulair.
Emily: She does experience episodes of chest pain/trouble breathing but does not often have the same kind of 'attacks' that Shawn does and I generally only hear wheezing when she is ill, and not even always then. When she is ill she always coughs up junk, and when she coughs during airway clearance when healthy, I can hear junk moving around. She does gain some relief from doing her treatments (we always do her nebs or inhaler and if possible, her vest, if she experiences chest pain or trouble breathing) it's not sudden, drastic improvement as her brother experiences. There is a clear difference between the 2 of them. Hers is a more low-level chronic thing that severely flares when sick, Shawn's is far more acute during attacks but then is largely a non-issue almost all the time.
PFT's/xray:
Shawn's are not good. His fev1 prior to starting daily Singulair was only in the low 70's and small airways in the mid-50's. After a few months on meds, it went up a little bit (fev1 82%, small airways 60%). However, his chest xray was CLEAR. I was told this is more consistent with asthma.
Emily's are very good when she is healthy, drop a lot when she is sick, then rebound. However, her chest xray shows signs of change consistent with cf.
