Objective: The aim of our study was to examine longitudinal changes in bone mineral density (BMD) of children and adolescents with Crohn disease (CD), and risk factors related to low BMD., Patients and Methods: All patients ages from 2 to 18 years with CD who underwent dual-energy X-ray absorptiometry (DXA) at diagnosis and at the end of follow-up between 1999 and 2018 were considered for inclusion in this retrospective study. Factors related to changes in BMD at diagnosis and during follow-up were investigated., Results: One hundred and ninety-three patients had the two DXA required. At diagnosis, 36 patients (18.7%) had a low BMD.At the end of follow-up, 31 patients (16%). One hundred and sixty-four patients did not have the two DXA required.In included CD, BMD values were lower in the lumbar spine (LS) than in total body less head (TBLH), as well at diagnosis (P < 0.0001) or at the end of follow-up (P = 0.001).At diagnosis, only growth impairment or low BMI was associated with low BMD (P < 0.0001), only cumulative dose of corticosteroid at the end of follow-up (P = 0.01)., Conclusion: The high prevalence of low BMD in children and adolescents with IBD highlights the importance of evaluating BMD in these patients at the time of diagnosis and throughout the course of their treatment. Special attention must be given to patients with height delay or low BMI at diagnosis. Long-term glucocorticoid therapy is the main clinical risk factor associated with low BMD at the end of follow-up., Competing Interests: Conflicts of interest: C.M.V. received honoraria, speaker's fees and/or congress fees from AbbVie, MSD, Nestle, Biogen, Adacolumn.

Purpose: This randomized trial evaluated the efficacy and toxicity of sequential gemtuzumab ozogamicin (GO) and standard chemotherapy in older patients with newly diagnosed acute myeloid leukemia (AML)., Patients and Methods: Patients (n = 472) age 61 to 75 years were randomly assigned to induction chemotherapy with mitoxantrone, cytarabine, and etoposide preceded, or not, by a course of GO (6 mg/m(2) on days 1 and 15). In remission, patients received two consolidation courses with or without GO (3 mg/m(2) on day 0). The primary end point was overall survival (OS)., Results: The overall response rate was comparable between the two arms (GO, 45%; no GO, 49%), but induction and 60-day mortality rates were higher in the GO arm (17% v 12% and 22% v 18%, respectively). With median follow-up of 5.2 years, median OS was 7.1 months in the GO arm and 10 months in the no-GO arm (hazard ratio, 1.20; 95% CI, 0.99 to 1.45; P = .07). Other survival end points were similar in both arms. Grade 3 to 4 hematologic and liver toxicities were greater in the GO arm. Treatment with GO provided no benefit in any prognostic subgroup, with the possible exception of patients age < 70 years with secondary AML, but outcomes were significantly worse in the oldest age subgroup because of a higher risk of early mortality., Conclusion: As used in this trial, the sequential combination of GO and standard chemotherapy provides no benefit for older patients with AML and is too toxic for those age ≥ 70 years.
