Hello Dr. Braverman,

I have a question about DQ alpha and NK cells. I am 36 yrs old and have undergone 7 IVF cycles so far. I got pregnant on my first IVF cycle, but miscarried at 6.5 weeks. After the first 3 failed cycles, I got a second opinion and found that my husband and I have a partial DQ alpha match as well as elevated NK cells. Under the advise of my current RE, we did banking cycles to get as many embryos as possible before attempting transfer. Unfortunately the last 2 cycles did not yield any viable embryos and I am weighing my options on the embryos I have frozen. Do you think from my below test results, I would be better off with using a surrogate rather than compromising my remaining embryos? Do you think the HLA matches are significant in my case?
My HLA panel results:DQ Beta: 03, 06HLA-A: 01, 24HLA-B: 07,15HLA-C: 07, 08HLA-DRB1: 12, 15, DRB3, DRB5 presentDQ Alpha: 1.3, 4.3Husband's HLA panel results:DQ Beta: 02, 06HLA-A: 01, 30HLA-B: 13, 57HLA-C: 06, 06HLA-DRB1: 07, 15, DRB4, DRB5 presentDQ Alpha: 1.3, 2.0

Ok if you only have a few embryos left , then I suggest we talk at some point so I can go over this case carefully to help you make the decisison. You do appear to have significangt HLA issues, but I need to know more to give you advice.
