Abstract

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.

Abstract

<p><strong>BACKGROUND: </strong>The number of patients undergoing autologous haematopoietic cell transplant (HCT) is growing, but little is known about the factors that predict adverse outcomes. Low muscle mass and obesity are associated with disability and premature mortality in individuals with non-malignant diseases and may predict outcomes after autologous HCT.</p>

<p><strong>METHODS: </strong>This was a retrospective cohort study of 320 patients who underwent autologous HCT for Hodgkin or non-Hodgkin lymphoma between 2009 and 2014. Sarcopenia {skeletal muscle index male: &lt;43 cm/m [body mass index (BMI) &lt; 25 kg/m ] or &lt; 53 cm/m [BMI ≥ 25 kg/m ] and female: &lt;41 cm/m [regardless of BMI]) and obesity [total abdominal adiposity ≥450.0 cm (male), ≥396.4 cm (female)] were assessed from single-slice abdominal pre-HCT computed tomography images. Length of hospital stay, first unplanned intensive care unit admission, and 30-day unplanned readmission were evaluated based on body composition using multivariable regression analysis, and mortality was evaluated with Kaplan-Meier analysis and Gray's test.</p>

<p><strong>RESULTS: </strong>Median age at HCT was 53.3 years (range, 18.5 to 78.1 years); 26.3% were sarcopenic and an additional 7.8% were sarcopenic obese pre-HCT. Sarcopenic obesity was associated with increased risk of prolonged hospitalization [odds ratio (OR) = 3.6, 95% confidence interval (CI) 1.3-9.8], intensive care unit admission (OR = 4.7, 95% CI 1.5-16.1), and unplanned readmission after HCT (OR = 13.6, 95% CI 2.5-62.8). Patients who were sarcopenic obese also had the highest mortality risk at 1 year [hazard ratio (HR): 3.9, 95% CI 1.1-11.0] and 5 years (HR: 2.5, 95% CI 1.1-5.5), compared with patients with normal body composition. Sarcopenia alone, but not obesity alone, was associated with an increased risk of these outcomes, albeit with a lower magnitude of risk than in patients who were sarcopenic obese.</p>

<p><strong>CONCLUSIONS: </strong>Sarcopenic obesity was an important predictor of outcomes in patients undergoing autologous HCT. These findings could inform targeted prevention strategies in patients at highest risk of complications after HCT.</p>
