Effectiveness of Dexamethasone for COVID-19 in Hospitalized Patients With Diabetes: A Retrospective Cohort Study

DOI record: { "DOI": "10.1210/clinem/dgae734", "ISSN": [ "0021-972X", "1945-7197" ], "URL": "http://dx.doi.org/10.1210/clinem/dgae734", "abstract": "<jats:title>Abstract</jats:title>\n <jats:sec>\n <jats:title>Background</jats:title>\n <jats:p>Patients with diabetes have higher mortality from COVID-19 compared to the general population. Dexamethasone, a potent glucocorticoid used for moderate to severe COVID-19, can worsen hyperglycemia in patients with diabetes, potentially leading to worse outcomes. The efficacy and safety of use of dexamethasone for COVID-19 in patients with diabetes needs further evaluation.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Objective</jats:title>\n <jats:p>The study aimed to assess the efficacy and safety of dexamethasone in patients with diabetes hospitalized for COVID-19 infection.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Design</jats:title>\n <jats:p>This retrospective study analyzed data from 5 hospitals in the Johns Hopkins Health System collected between March 3, 2020, and June 25, 2022. Propensity score matching was applied to a cohort of patients with diabetes who received dexamethasone and those who did not (controls), and outcomes were compared using Cox proportional hazards regression models.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Outcomes</jats:title>\n <jats:p>The primary outcome was time to death within 28 days. The secondary outcome was time to clinical improvement. Additional outcomes included the incidence of hyperglycemic emergencies and subgroup analysis of primary outcomes by clinical severity.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Results</jats:title>\n <jats:p>Out of 10,329 patients admitted for COVID-19, 3679 had diabetes, and 2361 met the inclusion criteria. After propensity score matching, 529 patients were analyzed in each group. Survival rates between the dexamethasone and control groups during the 0- to 6-day and 7- to 28-day periods and time to clinical improvement at 28 days did not differ significantly. There was no difference in the incidence of diabetic ketoacidosis or hyperosmolar hyperglycemic state between the groups.</jats:p>\n </jats:sec>\n <jats:sec>\n <jats:title>Conclusion</jats:title>\n <jats:p>Dexamethasone treatment did not significantly improve survival or time to clinical improvement in patients with diabetes and COVID-19 infection. Further prospective studies are needed to confirm these findings and determine potential mechanisms.</jats:p>\n </jats:sec>", "author": [ { "ORCID": "https://orcid.org/0000-0003-0304-4044", "affiliation": [ { "name": "Division of Endocrinology, Diabetes and Metabolism, Department of Medicine, Johns Hopkins University School of Medicine , Baltimore, MD 21287 ,", "place": [ "USA" ] } ], "authenticated-orcid": false, "family": "Bhat", "given": "Salman Zahoor", "sequence": "first" }, { "affiliation": [ { "name": "Department of Pediatrics, Biostatistics, Epidemiology and Data Management (BEAD) Core, Johns Hopkins University School of Medicine , Baltimore, MD 21224 ,", "place": [ "USA" ] } ], "family": "Wu", "given": "Jiajun", "sequence": "additional" }, { "ORCID": "https://orcid.org/0000-0002-5482-6620", "affiliation": [ { "name": "Department of International Health, Johns Hopkins Bloomberg School of Public Health , Baltimore, MD 21205 ,", "place": [ "USA" ] } ], "authenticated-orcid": false, "family": "Perin", "given": "Jamie", "sequence": "additional" }, { "affiliation": [ { "name": "Department of Applied Mathematics and Statistics, Johns Hopkins University , Baltimore, MD 21218 ,", "place": [ "USA" ] } ], "family": "Wang", "given": "Kunbo", "sequence": "additional" }, { "affiliation": [ { "name": "Division of Infectious Diseases, Department of Medicine, Johns Hopkins School of Medicine , Baltimore, MD 21287 ,", "place": [ "USA" ] } ], "family": "Robinson", "given": "Matthew L", "sequence": "additional" }, { "affiliation": [ { "name": "Division of Pulmonary and Critical Care Medicine, Department of Medicine, Johns Hopkins School of Medicine , Baltimore, MD 21287 ,", "place": [ "USA" ] } ], "family": "Garibaldi", "given": "Brian T", "sequence": "additional" }, { "ORCID": "https://orcid.org/0000-0002-0210-655X", "affiliation": [ { "name": "Division of Endocrinology, Diabetes and Metabolism, Department of Medicine, Johns Hopkins University School of Medicine , Baltimore, MD 21287 ,", "place": [ "USA" ] } ], "authenticated-orcid": false, "family": "Mathioudakis", "given": "Nestoras", "sequence": "additional" } ], "container-title": "The Journal of Clinical Endocrinology &amp; Metabolism", "content-domain": { "crossmark-restriction": false, "domain": [] }, "created": { "date-parts": [ [ 2024, 10, 17 ] ], "date-time": "2024-10-17T18:29:54Z", "timestamp": 1729189794000 }, "deposited": { "date-parts": [ [ 2024, 10, 29 ] ], "date-time": "2024-10-29T05:51:12Z", "timestamp": 1730181072000 }, "funder": [ { "name": "Christopher D.
