We have an infant who has was tested with Lectins and was found to have Tk-transformed polyagglutination, most likely due to necrotizing enterocolitis.  Any recommendations for transfusions?  Infant is O positive, and seems to get a better bump in lab values when transfused with washed RBCs vs unwashed RBCs.  The problem, of course is the increased donor exposure for this patient due to the fact that washed cells expire every 24 hours.  Patient also needs platelet transfusions.  Any thoughts on if washed products are indicated and if so for how long do you continue to give washed products?

 

I can't sure that Tk  polyagglutination is caused by disease, in my memory it seems inborn, I am not sure of this.

I will give washed RBCs and washed platelet.

Just google it ,and found that Tk polyagglutination is caused by bacteria infection.
