infection

Hi - I imagine you already did CGD testing, but with homozygosity of
chromosome 1 (uniparental disomy or distant consanguinity) a recessive NCF2
mutation could cause symptoms consistent with this presentation, not sure if
it is in the region of homozygosity.  You might even want to go back and
look @ the DHR flow to make sure it is truly normal if it was done.
 
Best,

Subject: [cis-pidd] Infant with severe diarrhea and pseudomonas infection
 

I would be grateful for some direction as to where to go with this infant,
who presented at 6 weeks of age with severe diarrhea, pseudomonas at 3 sites
and thrombophilia .    Any suggestions for further analysis would be
helpful, particularly if you add where they could be obtained.  The
insurance is poor.
 
The patient is now 4 mos of age.  He was born to non-consanguinous parents
of an uncomplicated pregnancy by C-section as this was the third repeat
C-section.  He had no in-hospital complications; he was fed by breast milk.
Newborn screen, including TRECs, was normal.  At approximately 6 weeks of
age his mother noted some blood streaks in the stool and his stooling
increased in frequency.  He became irritable and was sent to the emergency
service where he was noted to have a scaly rash and be severely dehydrated
with a temperature of 102.  He was admitted for rehydration and evaluation
for infection. 
Multiple consults to evaluate initial elevated WBC, elevated creatinine,
hyperkalemia, skin rash, diarrhea were obtained with the following opinions:
stressed marrow due to severe dehydration, kidney injury due to severe
dehydration, CAH negative, skin rash was non-specific xerosis.
Gastroenterology gave  an extensive differential diagnosis but no specific
etiology was noted for diarrhea.
Approximately one week into his hospitalization he was noted to have an
external otitis which cultured positive for Pseudomonas which provoked an
Immunology consultation.  History was notable for a death at age 2 of his
mother¹s sister  (maternal aunt) possibly due to meningitis.  His father
brother (paternal uncle) died at age one of unknown cause.  Both of these
deaths occurred in South America.
He progressed to have a neck mass.  On CT imaging a jugular vein thrombosis
as well as a sub-mandibular abscess was seen.  This was due to Pseudomonas
and required drainage.  A Broviac catheter was placed and the subcutaneous
track became infected, also with Pseudomonas.   The broviac was removed and
a line inserted in the groin.  This immediately became partially thrombosed
but did not become infected and did not have to be pulled.  He was (and is)
treated with low-molecular weight heparin.
Immunology workup so far normal as follows:  CBC ­ WBC initially >50,000 but
decreased and remained at 15 to 10 K, ANC 4K to 8K, ALC 2K to 6K, platelets
280 to 600K, normal size
Repeat TREC (Mayo) normal
CD3--4847
CD4 ­ 3794
CD8--984
CD56--140
CD19‹2037
CD20‹29%
CD4+CD45RA+75%, CD4+CD45RO+25%
FISH for maternal cells ­ 100% XY
Mitogens to  PHA, PWM ³normal² (Mayo)
CD18 normal
CH50 - normal
TLR (ARUP)  - normal cytokine production to 6  ligands
Wiscott Aldrich normal
Normal IgG and M (drawn to determine if he needed Ig replacement of maternal
Abs due to severe enteropathy)
Microarray showed no clinically significant copy #s but a long stretch of
homozygosity at Chromosome 1.
Thrombophilia evaluation was non revealing.
 
He was discharged mid-December and I saw him Dec. 30.  He looked well and
was gaining weight on an elemental formula, although gastroenterology feels
his weight  gain could be more robust.
