IgmAmie had her follow-up appointment with the immunologist yesterday & it was quite interesting.
It appears that her immune system is better than many little ones that had a "hypoplastic thymus". Our immunologist (who by the way I think is wonderful!) has consulted with the guru of immunology from Duke & they are both surprised with her results.
It appears that her base immunology cells (I hope I get this right) -- the Igm is extremely low (normal is 47-240 & hers is 29). The Igm is supposed to be the baseline for all other immunology cell building in the body. So, you would think with this extremely low Igm the rest would be low as well -- right??
Well not so fast, some how, some way -- little Missy has built quite a nice amount of Iga & Igg's (not a perfect amount, but a pretty spectacular amount, since the base is so low!).
Next we talked about the different T & B cells & again -- many things are low -- but not as low as they expected. Some of her immunity from vaccinations is actually in the normal range (some not so good).
The way she basically explained it is that her body doesn't know exactly what to do when a foreign substance invades her body (like the vaccines) -- so it doesn't do quite as good of a job of building resistane.
Additionally, she is at increased risk for infections of any kind. So, we will have to be careful to make sure that if anyone knows of someone that has an infection -- we keep her away from them.
The immunologist also found two journal articles that discussed immunology issues with the chromosome deletion of 16p11.2 (that is the deletion that we recently found out Amie has). Evidently, there is a gene in this area that is specific to the thymus & immunology...so again -- we're pretty darn lucky that she's doing as well as she is!!!
