Dear all,

This is a f/u.
His thyroid fx still abnormal: endocinology people say this could be
secondary hypothyroidism (low free T4 and still low TSH). I think this
child
might have abnormal HPA axis..wonder about GH def as well. I read some
articles about GH insensitivity and immune deficiency (hyper IgM was
reported, STAT 5b mutation was reported..) and growth retardation (this
child weighs 7 kg at 20 mo of age).

We plan to do ACTH stimulation test and GH hormone measurement tomorrow
and STAT flow on monday..

Dear Dr. Sullivan did you mean DKC (dyskeratosis congenita)? He does not
seem to have mucocutaenous findings and nail findings of it.

His lung condition is getting bad (not ARDS yet) with increasing CRP,
more sputum, patchy pulmonary infiltration and pancytopenia : he is now
on
meropenem, vancomycin, amphotericin, ganciclovir (antigenemia),
oseltamivir
(still influenza positive)...

I appreciate further comments.

YaeJean

------------------------------------------------------------------------------
Other question from  another colleague,


Is there consanguinity? -> *no*

Does he have liver, spleen, lymph node changes? ->* liver is enlarged.*



Could this be HLH (NK=0)? ->  *checked for HLH criteria...not yet
satisfied.
*



I can’t see platelets – is that the 142K? -> yes it was 142k but now it
is
31K

Have you done ferritin, lipids? -> *will f/u the labs. Ferritin was not
superhigh, TG was ok. *

Does DHR negative mean no activity? It doesn’t sound like CGD.-> *I
meant
normal DHR. *
