Summary of "Higher risks of toxicity and incomplete recovery in 13-17 year old females after marrow donation: RDSafe peds results."

Although donation of bone marrow (BM) or peripheral blood stem cells (PBSC) from children to family members undergoing allogeneic transplantation are well-established procedures, studies detailing levels of pain, symptoms, and long-term recovery are lacking. To address this, we prospectively enrolled 294 donors age <18 at 25 pediatric transplant centers in North America, assessing them pre-donation, peri-donation, 1 month, 6 months, and 1 year after donation. We noted that 71% of children reported pain and 59% other symptoms peri-donation, with resolution to 14% and 12% at 1 month. Both older age (age 13-17 vs. younger) and female sex were associated with higher levels of pain peri-donation, with the highest rates in older females (57% and 17% reporting grades 2-4 and 3-4 pain, respectively). Multivariate analyses showed a 4-fold increase in risk for older females compared to males <13 (p<0.001)). At 1 year, 11% of 13-17 year old females reported grade 2-4 pain compared to 3%, 0%, and 1% of males aged 13-17, females <13, and males <13 (p=0.01). Males and females 13-17 years old failed to return to pre-donation pain levels at 1 year 22% and 23% of the time compared to 3% and 10% in males and females <13 (p=0.002). In conclusion, females age 13-17 are at increased risk for grade 2-4 pain at 1 year and more than 20% of females and males 13-17 do not return to baseline pain levels 1 year after BM donation. Studies aimed at decreasing symptoms and improving recovery in older children are warranted.
