BACKGROUND: Allogeneic hematopoietic cell transplantation (HCT) recipients have increased risk of developing glucose intolerance and diabetes mellitus (DM). The strongest risk factor for glucose intolerance is being overweight/obese, as determined by body mass index (BMI), which does not account for differences in body composition. We examined the association between body composition measures from pre-HCT CT and early-onset (≤30 days) de novo glucose intolerance after HCT, and determined its impact on nonrelapse mortality (NRM).

METHODS: This study included 749 patients without pre-HCT DM. Skeletal muscle loss [abnormal skeletal muscle gauge (SMG)] and abnormal visceral adiposity (VA) were defined by sex-specific tertiles. Fine-Gray proportional subdistribution HR estimates and 95% confidence intervals (CI) were obtained to determine the association between muscle loss and VA and development of glucose intolerance. 1 year NRM was calculated for patients alive at day 30.

RESULTS: Median age at HCT was 50.2 years. By day 30, 8.1% of patients developed glucose intolerance and 731 remained alive. In multivariable analysis, abnormal SMG was associated with increased risk of glucose intolerance in nonoverweight (BMI < 25 kg/m2) patients (HR = 3.00; 95% CI, 1.15-7.81; P = 0.024); abnormal VA was associated with increased risk of glucose intolerance in overweight/obese patients (HR = 2.26; 95% CI, 1.24-4.12; P = 0.008). Glucose intolerance was independently associated with NRM (HR = 1.88; 95% CI, 1.05-3.39; P = 0.035).

CONCLUSIONS: Abnormal SMG and VA were associated with glucose intolerance in nonoverweight and overweight/obese patients, respectively, which contributed to increased risk of 1 year NRM.

IMPACT: This information may guide personalized interventions to decrease the risk of adverse outcomes after HCT.
