Abstract:
Rationale: Many studies have shown the importance of body composition parameters, muscle, and fat mass, evaluated by several methods in hematopoietic stem cell transplantation (HSCT) outcomes. Ultrasound (US) is an efficient and low-cost method to evaluate body composition, even though there have not been many studies in HSCT. Objectives: Our goal was to investigate the muscle, visceral fat (VF), and echogenicity before HSCT and after engraftment, evaluated by US and its association with outcomes. Methods: All adult patients with hematological malignances admitted for HSCT autologous and allogeneic were eligible to enter this prospective study. Their thigh muscle thickness, VF, and echogenicity were evaluated by US on the first day of hospitalization (baseline) and after engraftment (15–25 days post-HSCT).
