Sažetak
Nutritional status is recognized as an independent and modifiable risk factor of outcome in stem cell transplant. Our research aim was to evaluate the impact of body mass index (BMI) and serum albumin on the prevalence of adverse events and survival in autologous transplant in children. A retrospective study was conducted of autologous transplants performed between 2006 and 2017 in the Children’s Hospital Zagreb, Croatia. Nutritional status was assessed at the times of diagnosis, procedure, and discharge using BMI (underweight, normal, obese) and serum albumin (grades 1–4). Adverse events (fever, gastrointestinal toxicity, electrolyte disturbances, dysglycemia) and outcome (3-year, relapse, mortality) were documented. Seventy-seven children (54.5% males, mean age 7.9 years) underwent autologous transplant, mostly for neuroblastoma. In terms of BMI and albumin, which showed significant positive correlation at diagnosis (p = 0.026) and transplant (p = 0.016), most participants were well nourished. Average post-transplant weight loss was 4%. Major toxicities were severe mucositis (72.7%) and hypophosphatemia (31.2%). Relapse and mortality rates were 35.1% and 42.9%, respectively. Hypokalemia (p = 0.041) and hypomagnesemia (p = 0.044) were more prevalent in the underweight group, while obese children experienced significantly less severe mucositis (p = 0.016) and hypophosphatemia (p = 0.038). There was no significant difference regarding outcome among children of different nutritional status, although undernourished children tended to have lower relapse and mortality rates. In conclusion, underweight children are significantly more prone to severe electrolyte disorders and mucositis, and although statistical significance was not reached, are more likely to survive.
