Abstract (original English)

Posttransplantation diabetes mellitus (PTDM) is a frequent complication after allogeneic stem cell transplantation (allo-SCT), important for its negative impact on cardiovascular health. Risk factors for PTDM are not well defined. We conducted a prospective study to investigate the risk factors and incidence for PTDM in the first 100 days after allo-SCT. A total of 84 patients completed the study, 60% of whom developed PTDM. In a multivariate logistic regression model, pretransplantation c-peptide level (>3.6 ng/mL; odds ratio [OR], 5.9; 95% confidence interval [CI], 1.77-20.22; P = .004), unrelated donor allo-SCT (OR, 4.3; 95% CI, 1.34-14.2; P = .014), and peak steroid dose >1 mg/kg/day (OR, 5.09; 95% CI, 1.19-23.2; P = .035) were identified as independent predictors of PTDM. In addition, overall survival (OS) was inferior in patients with PTDM compared with those without PTDM (mean survival, 2.26 years vs 2.7 years; P = .021). Pretransplantation c-peptide level greater than the cohort median (>3.6 ng/mL) also was associated with inferior OS (mean, 1.7 years vs 2.9 years; P = .012). In a multivariate Cox proportional hazards model, high-risk disease (hazard ratio [HR], 2.34; 95% CI, 1.09-5.28; P = .029) and pretransplantation c-peptide level >3.6 ng/mL (HR, 1.05; 95% CI, 1.01-1.09; P = .013) were independent predictors of OS when adjusted for systemic steroids and regimen inte
