Graft-vs-host disease (GVHD) is a major complication after allogeneic hematopoietic stem cell transplantation VSports手机版. Both acute and chronic forms of GVHD are challenging to manage medically and nutritionally. Patients with advanced GVHD commonly become depleted nutritionally, with loss of lean body mass (LBM) and functional status. We present 2 case reports of patients who developed GVHD and subsequent nutrition decline. Although both patients were candidates for specialized nutrition support (SNS), only 1 was able to receive enteral and parenteral nutrition due to GVHD complications preventing access for provision of SNS. Fortunately, the patients have remained in remission from their hematologic malignancy, but they continue to cope with chronic GVHD and its consequences. These cases exhibit the complexity of managing a patient with extensive GVHD and nutrition interventions for clinicians to consider to optimize outcomes. .
