Although insulin remains the standard therapy, oral metformin presents a promising alternative due to its ease of use, lower risk of hypoglycemia, and noninvasive route of administration\u2014factors that can significantly enhance patient comfort and quality of life.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To evaluate the efficacy and safety of oral metformin in managing therapy\u2010induced hyperglycemia (TIH) in children with ALL.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods<\/jats:title>\n An ambispective analysis was conducted over 6 years (September 2018\u2013August 2024) in pediatric ALL patients who developed hyperglycemia during induction or re\u2010induction. We assessed the effectiveness of metformin in controlling hyperglycemia and the need for insulin in cases of suboptimal response.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Out of 281 ALL patients, 54 (19.2%) developed TIH, with a median age of 12 years (range 5\u201316). Most cases (57.4%,\n n<\/jats:italic>\n \u00a0=\u00a031) occurred in the preadolescent\/adolescent group. Pre\u2010B ALL accounted for 85.2% (\n n<\/jats:italic>\n \u00a0=\u00a046), and T\u2010ALL for 14.8% (\n n<\/jats:italic>\n \u00a0=\u00a08). A WBC count >20\u00a0\u00d7\u00a010\n 9<\/jats:sup>\n \/L was noted in 44.4% (\n n<\/jats:italic>\n \u00a0=\u00a024). BMI was normal in 63% (\n n<\/jats:italic>\n \u00a0=\u00a034), whereas 22.2% (\n n<\/jats:italic>\n \u00a0=\u00a012) were overweight. Extremes of BMI (underweight\/obese) were seen in 7.4% (\n n<\/jats:italic>\n \u00a0=\u00a04) each. Most cases occurred during induction (49 patients), with 17 experiencing recurrence during re\u2010induction. Hyperglycemia typically appeared within a week of initiating steroids. The mean baseline glucose was 240\u00a0mg\/dL (range: 201\u2013338\u00a0mg\/dL), which declined to 137\u00a0mg\/dL at Day 7 (range: 110\u2013174\u00a0mg\/dL), with a mean reduction from baseline of 103\u00a0mg\/dL. Metformin (up to 1500\u00a0mg\/day) successfully controlled blood glucose in 36 induction\u2010phase patients (73.4%, 95% CI 59.7\u201383.8), whereas 13 (26.5%) required insulin. During re\u2010induction, seven patients needed dual therapy. Insulin was added for glucose >300\u00a0mg\/dL, signs of ketoacidosis, or poor response to metformin. In the TIH group, febrile neutropenia and culture\u2010positive sepsis occurred in 42.6% (\n n<\/jats:italic>\n \u00a0=\u00a023) and 24.1% (\n n<\/jats:italic>\n \u00a0=\u00a013), respectively\u2014higher than in non\u2010hyperglycemic patients. All patients reverted to euglycemia after steroid tapering, with no long\u2010term hypoglycemic therapy needed. Metformin was well\u2010tolerated, with no adverse effects warranting discontinuation. Glycemic management did not interfere with leukemia remission or treatment completion.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Oral metformin proved to be a safe and effective first\u2010line option for managing TIH in pediatric ALL. Insulin therapy could be avoided in majority of the patients (73.4% in induction, 68.1% in re\u2010induction), making this drug an attractive first\u2010line option for children with treatment\u2010induced non\u2010severe hyperglycemia.<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/1545-5017.70185","type":"journal-article","created":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T10:56:43Z","timestamp":1773399403000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Use of Oral Metformin Therapy for Therapy\u2010Induced Hyperglycemia in Pediatric Patients With Acute Lymphoblastic Leukemia"],"prefix":"10.1002","volume":"73","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4042-6415","authenticated-orcid":false,"given":"Ankita","family":"Chakraborty","sequence":"first","affiliation":[{"name":"Department of Pediatric Hematology\u2010Oncology and BMT Sir Ganga Ram Hospital New Delhi India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2570-7750","authenticated-orcid":false,"given":"Manas","family":"Kalra","sequence":"additional","affiliation":[{"name":"Department of Pediatric Hematology\u2010Oncology and BMT Sir Ganga Ram Hospital New Delhi India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Archana Dayal","family":"Arya","sequence":"additional","affiliation":[{"name":"Pediatric Endocrinology Sir Ganga Ram Hospital New Delhi India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anupam","family":"Sachdeva","sequence":"additional","affiliation":[{"name":"Department of Pediatric Hematology\u2010Oncology and BMT Sir Ganga Ram Hospital New Delhi India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,13]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/pbc.28085"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPH.0b013e31829cdeba"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/pedi.12773"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPH.0000000000002494"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/leu.2008.289"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/pbc.28475"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pedneo.2015.01.008"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(81)80955-9"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-011-1307-5"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1177\/1078155219873048"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.3329\/bjch.v45i3.62891"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1530\/EJE-16-0653"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1177\/1060028017728297"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1038\/cddis.2012.13"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2141.2009.07657.x"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/434195"},{"key":"e_1_2_11_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/pbc.21505"},{"key":"e_1_2_11_19_1","first-page":"479","article-title":"How to Manage Steroid Diabetes in the Patient With Cancer","volume":"4","author":"Oyer D.
