[CIS PIDD] Angioedema in CVID

[Routes, John]

Kate
Despite his lack of response to icatibant, I would try prophylaxis with
c1q-inhibitor ----could also try early treatment with c1q-inhibitor if he
does not have frequent enough episodes to warrant prophylaxis.

> Hi all-

> Appreciate any thoughts.

> 

> 15 year old boy who has CVID-specific antibody deficiency.  He doesn't quite

> fulfill the diagnosis for CVID (low IgG only and poor vaccine responses).  He

> was diagnosed about 4 years ago and has been on immunoglobulin replacement

> ever since.  He did quite well until a year ago when he started developing

> angioedema.  The episodes are ALWAYS head and neck.  He does have an allergic

> disposition and has had a few episodes of hives in his life and has required

> an inhaler for asthma since a young age but his allergies have not been a big

> deal.

> 

> This angioedema is a HUGE deal.  Starting a year ago, he has had angioedema

> over half the days and has been in the ICU multiple times.

> 

> Here is what we know:

> 

> Labs:

> 

> Normal functional C1 esterase inhibitor

> Normal serial tryptases

> Normal eosinophil count

> Normal thyroid studies

> 

> Clinically:

> 

> The episodes are unpredictable and can be a little blip or a massive swelling

> that lasts for weeks.

> 

> The do NOT respond to steroids, Firazyr, high dose IVIG

> 

> The only thing the episodes respond to is epinephrine and he has had massive

> amounts of epi.  Although he responds, the swelling recurs until it has run

> its course.

> 

> Any thoughts????? We are running out of options.
