David was born with Hemophilia and developed Hemophagocytic Lymphohistiocytosis(HLH) due to infections. To treat HLH, doctors used chemotherapy. This chronic illness and chemotherapy caused David to develop Natural Killer (nk) cell dysfunction. David’s nk cells have compromised his immune system causing him to need a bone marrow transplant to get his immune system to work properly again.

David’s HLH has recently relapsed and his only hope for a cure is to find a marrow match.

Giving blood means bridging the space between two lives. One is healthy, vibrant and generous. The other is experiencing illness, trauma and uncertainty. Making a blood donation is one of the most intimate and priceless gifts one can give and The South Texas Blood & Tissue Center (STBTC) is honored to be the bridge between those two lives.

How do you prep for blood donation? Find out here.

GenCure, a partner and authorized donor center of the Be The Match Program (National Marrow Donor Registry), coordinates donor registration, marrow donation and search activities providing donor suitability, management, collection and processing of stem cells for patients hoping for a cure. Its marrow donor program hosts marrow registration drives and special events across South Texas to find donors for patients like Aaron and promote awareness about the urgent need for more potential donors.
