Methods This retrospective study included 25 patients with chronic myeloid leukemia (CML) treated with nilotinib at our hospital. Four patients had diabetes mellitus at the start of nilotinib administration (prior DM group), and five patients were newly diagnosed with diabetes mellitus after the start of nilotinib administration (new DM group). Sixteen patients who were not diagnosed with diabetes mellitus were classified into the non-DM group. Changes in the blood glucose and HbA1c levels were evaluated in each group at the time of nilotinib administration and two years later. Results Molecular genetic remission of CML was achieved in 81.8% of patients with diabetes and 72.2% of patients without non-DM group. There were no cases in this study in which nilotinib was changed or discontinued owing to hyperglycemia. There was no difference in the blood glucose levels at the start of nilotinib treatment among the groups. Two years after starting nilotinib, the blood glucose levels in the new DM group [232 (186-296) mg/dL] and prior DM group [168 (123-269) mg/dL] were significantly higher than those in the non-DM group [100 (91-115) mg/dL]. ΔHbA1c levels in the new DM group [1.3 (0.9-2.2) %] and prior DM group [1.6 (0.7-1.7) %] were significantly higher than those in the non-DM group [-0.2 (-0.3-0.1) %]. Conclusion Nilotinib caused diabetes in 23.8% of the participants, but there were no hyperglycemia-related severe adverse events. Therefore, nilotinib may be safely continued with regular monitoring for the development of diabetes after nilotinib administration.</p>","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"817-823"},"PeriodicalIF":1.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142092846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A bioelectrical impedance analysis (BIA) is a noninvasive method for measuring human body composition. A direct association between serum hemoglobin (Hb) levels and the extracellular water-to-total body water (ECW/TBW) ratio, as measured by a BIA in patients with diabetes, has been reported. However, the predictive value of the ECW/TBW ratio for detecting anemia in patients with CVD has not been fully elucidated. Methods We conducted a study involving consecutive patients admitted to our cardiology department from January 1, 2021, to December 31, 2022. A BIA was performed once during hospitalization for all patients, whenever possible. The correlation between the Hb level and ECW/TBW ratio was assessed. The predictive accuracy for anemia was evaluated using a receiver operating characteristic (ROC) curve analysis. Results The ECW/TBW ratio was significantly higher in the anemia group than in the non-anemia group (0.41 [0.40, 0.41] vs. 0.39 [0.38, 0.40], p<0.001). The ECW/TBW ratio exhibited a significant negative correlation with Hb, with an R value of 0.57 and a p-value of <0.01. However, this correlation coefficient decreased to 0.45 among subjects with BNP levels ≥200 pg/mL. The area under the ROC curve (AUC) for the ECW/TBW ratio for detecting anemia was 0.83. However, its predictive performance decreased in patients with BNP levels exceeding 200 pg/mL, with an AUC of 0.71.

However, there have been no real-world studies focusing on erenumab in East Asia that investigated its efficacy on migraine-associated symptoms and patient-reported satisfaction levels. Methods This single-center, observational, retrospective, real-world study examined patients who received at least three doses of erenumab at Keio University Hospital, Tokyo, Japan, between December 2021 and March 2023 as their first CGRP mAb treatment in a real-world setting. The patients were administered 70 mg of erenumab monthly. We assessed changes in monthly migraine days (MMDs), responder rates, migraine-associated symptoms including photophobia, phonophobia, nausea/vomiting, and patient-reported satisfaction levels. In addition, injection site reactions and other adverse events were recorded to investigate safety. Results Nineteen patients were considered eligible for the analysis. At 3 months, erenumab decreased MMDs by 6.6 (95% confidence interval, 2.3-10.8; p<0.01). The 50% responder rate was 42%.
