To this observer, this looks pretty profound. If you look at Figure one, there is no overlap. All the colors are in specific outlines. No areas of mixed colors. It looks to me like perfect prediction of acute ITP and chronic ITP. Oh my. That has got to be good news for parents.
If you want to understand a bit about 'T-SNE' and AI pattern recognition techniques,
here is an article on Wiki.
But the important take away is this stuff:
.. Fc-Gamma Receptor IIIb, CXCL8, BMP7, DEFA1, DEFA1B, HLA-DRB4, and HLA-DRB5 ...
It appears this list of immune system surface glycoproteins is a complete list of 'attributes' needed for prediction. Only a fully complete list can make accurate predictions. This sort of technique is much the same way I use IVIG and steroid response attributes as predictors of ITP clinical outcomes in my
ITP treatments table.
In the study's graph. If the attribute list was incomplete, then one would have areas of mixed colors. If the list was overly complete, or too many attributes, that is ok. Extra attributes become noise and noise has an average value of zero. The mathematics allows identifying and excluding unnecessary variables.
The RNA aspect, as opposed to DNA aspect, is new to me. Can anyone explain? LOL, give a dog a bone?
This study is a great start for more. It would be reasonable to expect another group to try to do the same research, but this time, on adults. See if the idea can be repeated with adults. One day SOON, a simple blood test could indicate the best course of ITP treatments to take.
Yes, that's it. Thought this was important enough to start a separate thread. On RNA, looks like I'll have to get a Google degree in RNA Studies to understand it, LOL. I wonder if 'epigenetics' plays a part too. Viruses switching genes on and off.
I think IVIG works on these receptors too. Maybe you know something about that? That IVIG makes phagocytes (who have these receptors on their surface) ineffective by plugging useless things (contents of IVIG) into their receptors. Something like that? That would make Danazol a kind of super IVIG but where its effects don't fade away. That one can get this effect for months and months at a time from a pill with little cost. Give the immune system time to make the correct self versus non self decision - without overwhelming feedback of platelet/TPO/megakaryocyte destruction.
