Thank you for the manuscript. I called our lab and indeed they do not double stain for CD45RA and RO unless I ask specifically.
I will look into getting this tested.
If this isn’t the answer, then maybe we have a subset of odd patients in their early adulthood with an odd naïve T cell predominance.

Hi Hey,
We had too a case where all T cells seemed CD45RA
( if you look back I sent it here too, the title was "Secondary amyloidosis and lack of memory T cells" )
The solution was neat ( thanks to Klaus Warnatz for the tip!!)
It looks like you used CD45RA and CD62L for identifying naive cells... however there is a CD45 polymorphism causing a splicing variant expressing both RA and RO variants on memory cells.. therefore if you identify memory as "RA -" it looks like everything is naive!
A very simple to check for this is stain for both CD45RA and CD45RO... in our case more then half of the T cells were indeed "double" positive CD45RA/RO

Hope this helps!

Hi Hey!
We have a few of these as well in Finland, usually both B and T naives are very high, age may be anywhere 20-45 (i.e. how can they survive?)... Igs and mitogens, vaccine responses and CD3+CD28 mostly ok...(no long term follow up of vaccine responses yet) phenotypes in ours are (still rather mild) are combined PIDD, WES (+/- CNV): no known genes, nor clearly good candidates.
Ours are not with urticaria, do not yet have a clue what is going on and follow them up...
So we are both missing something.

I have a 19 year old girl who had work up done by a community allergist for idiopathic urticarial and found to be lymphopenic.
Healthy, no autoimmunity, no infections.
She had very low T cells (CD4 246, CD8 274) but normal B and NK cells
The odd thing is that she had the highest naïve cell percentage I’ve seen in an adult.
Rest of the immune system work up normal including mitogens, antibodies and vaccine titers.

I asked two of the smartest immunologists I know, who advised me to repeat in a few months with thought that maybe it was just recovery post infection
I brought her back 4months later, and her lymphocyte count is a bit higher at CD4 353 now, and again a really high naïve T cell percentage.
I cut and paste labs below.

Otherwise fine. Am I missing something?
Should I just recheck her again in 6months or so?

I agree with Joe. You could also check if he makes T cell proliferative responses to Tetanus before proceeding with the first VZV.

I’m conservative with these types of patients.
I would check to see if the patient made specific antibodies to tetanus toxoid and Hib.
If he did, I would then give VZV first.
If he breaks out in florid varicella you can treat with acyclovir, but I would be hesitant to give MMR.
If he tolerates VZV then 1 month later give MMR.
Good luck.

Dear all,
I would like your advice regarding a patient just diagnosed with XLT (WAS mut. V332A). He presented with hiatal hernia and he underwent surgery shortly after birth. Afterwards he developed persistent mild lymphadenopathy (LC and inguinal), reason why he came to our attention. Common infectious diseases were excluded. He suffers from some mild eczema, he has IgE of 494 kU/L with egg specific IgE. He also has small platelet volume, but not thrombocytopenia so far. His lympho subsets are normal as well as immunoglobulin values.
We run a gene panel and we fund a mutation on WAS gene compatible with XLT. Lymphadenopathy progressively solved. He never had major infections and he doing well.
He is now 15 m/o and he needs to undertake MMR/Varicella vaccination. What would you suggest to do?
Looking forward your inputs!
Best wishes
Eleonora
