Sarcopenia among patients after allogeneic hematopoietic stem cell transplantation and the impact of chronic graft versus host disease

Purpose This study investigated the frequency and characteristics of sarcopenia among patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) with a specific focus on the chronic graft-versus-host disease (cGVHD) population and its association with malnutrition, vitamin D and clinical characteristics. Methods We assessed sarcopenia, vitamin D levels, and nutritional status in 73 patients who underwent allo-HSCT, of which 45 were diagnosed with cGVHD. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People (EWGSOP) criteria. Results Sarcopenia was diagnosed in 19.2% of patients after allo- HSCT with statistically no significant difference between cGVHD and non- cGVHD patients. The risk factor for sarcopenia was the male gender. Sarcopenia in allo-HSCT patients correlated strongly with malnutrition and with current corticosteroid treatment (p < 0.005). Among cGVHD patients sarcopenia additionally correlated strongly with the number of prior systemic immunosuppressive therapy lines (p < 0.005) and moderately with the intensity of immunosuppression, cGVHD severity global rating assessed by both the health care provider and the patient and joint and fascia cGVHD involvement (p < 0.05). Vitamin D deficiency was found in more than 54.8% of patients, but the correlation to sarcopenia was not found. Conclusion Sarcopenia was found to be common in long term survivors of allo-HSCT independently of the cGVHD diagnosis. Prospective longitudinal studies are needed for a better understanding of factors affecting the development of sarcopenia after allo-HSCT.
