Digital Public Defence: Kristin Aneta Joan Skaarud

MNSc Kristin Aneta Joan Skaarud at Institute of Basic Medical Sciences will be defending the thesis "The role of nutrition support for quality of life and clinical outcomes in adult recipients of allogeneic hematopoietic stem cell transplantation" for the degree of PhD (Philosophiae Doctor).

The public defence will be held as a video conference over Zoom.

The defence will follow regular procedure as far as possible, hence it will be open to the public and the audience can ask ex auditorio questions when invited to do so.

Allogeneic stem cell transplantation involves transferring the stem cells from a donor to the patient after high-intensity chemotherapy or radiation. This treatment is commonly used in patients with malignant blood disease and may cause eating problems requiring nutritional support. Nutritional support could be administered via a central venous catheter (parenteral) and via a feeding tube (enteral). There is no agreement on food recommendations, the optimal time point to start nutritional support, the dose of nutritional support, and optimal administration route. Finally, it is not known if nutritional intervention can improve quality of life and clinical outcomes in recipients of allogeneic stem cell transplantation.

The aims of the thesis were to assess the effect of optimized energy and protein intake preferably by the enteral route on quality of life and clinical outcomes in recipients of allogeneic stem cell transplantation. Patients were randomized to receive individually adjusted energy and protein intake combined with tube feeding supplemented with parenteral feeding if needed (intervention:=57), or regular hospital food and a standard dose of parenteral nutrition (controls:=60). We found no effect of the nutritional intervention on global quality of life, oral mucositis, acute graft-versus-host disease and other clinical outcomes at 3 months. Body composition during 1-year follow-up was the same in both groups. In the pooled groups, 1-year mortality was associated with weight gain (i.e. fluid retention). Loss of microbial diversity at 3 weeks was associated with 1-year mortality in both groups.

In conclusion, optimized energy and protein intake had no effect on quality of life and clinical outcomes in recipients of allogeneic stem cell transplantation.
