GI track bleeding

Has anyone dealt with GI Bleeding as a complication of extended low platelets?

My 18 yo daughter had an episode of GI bleeding in February. Her platelet count had been <5,000 (they have basically been <10,000 since July and <5,00 since December) and we were doing watchful waiting trying to avoid medication side effects. She had several episodes of bright red bleeding with bowel movements. When we went to the doctor her platelet count was 1 (which I think was pretty generous) and her hemoglobin had dropped 2.5grams so she was admitted and had 2 high dose SoluMedrol infusions and IVIG in the middle, and was sent home on 3 weeks of tapered Prednisone. The good news is she responded very well, no further GI bleeds and her platelet count continued to increase even after her Prednisone was stopped. It has been about 2 months now and she is still doing very well, minimal normal bruising, no petechiae, no evidence of low counts. She is due for bloodwork at the end of the month.

Looking back even though her counts had been very low for several months there were subtle changes in the 1-2 weeks prior to the bleed that I would notice if she is in the same situation again. She had much more petechiae, she was really bruised and the bruising was really dark to black. And a couple days before she had a few blood blisters in her mouth which she really had not had before. And total fatigue. I would take some of these changes a little more seriously if we are in this situation again.
