Brief summary
The goal of this clinical trial is to investigate whether dapagliflozin can help prevent glucocorticoid-induced hyperglycemia (GIH) in hospitalized patients requiring high-dose glucocorticoids (GCs). This trial will also assess the safety of dapagliflozin when used alongside GCs. The main questions the trial aims to answer are: Does dapagliflozin reduce the incidence of GIH in patients receiving high-dose GCs? What side effects or adverse events occur in patients taking dapagliflozin alongside high-dose GCs? Researchers will compare dapagliflozin to standard glucose monitoring (SGM) to determine if dapagliflozin is effective in preventing GIH in patients receiving high doses of GCs. Participants will: Take dapagliflozin (10 mg/day) or undergo standard glucose monitoring during their hospital stay. Visit the hospital for regular check-ups and glucose testing during their treatment. Record their glucose levels multiple times a day and report any adverse events they experience.
Detailed description
This clinical trial aims to evaluate the efficacy and safety of dapagliflozin in preventing glucocorticoid-induced hyperglycemia (GIH) in hospitalized patients who require high-dose glucocorticoid (GC) treatment. GCs are commonly used in clinical practice for their potent anti-inflammatory and immunosuppressive properties, but they are also a major cause of medication-induced hyperglycemia, particularly when administered at high doses. The hypothesis of this trial is that dapagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, may reduce the incidence of GIH by counteracting the metabolic disturbances caused by GCs. Dapagliflozin works by inhibiting the SGLT2 protein, which is responsible for glucose reabsorption in the kidneys. By inhibiting this protein, dapagliflozin promotes glucose excretion in the urine, helping to reduce blood glucose levels. This mechanism is particularly relevant in the context of GIH, as GCs can impair insulin secretion, promote hepatic gluconeogenesis, and increase peripheral insulin resistance. The primary aim of the study is to compare the incidence of GIH in patients receiving dapagliflozin versus those undergoing standard glucose monitoring (SGM) while on high-dose GCs. Secondary objectives include assessing the cumulative incidence of GIH days, the number of hyperglycemic crises, and the need for insulin therapy. The study also evaluates the safety profile of dapagliflozin, particularly focusing on any adverse events associated with its use in this population. The adverse effects of high-dose GCs will also be reported to provide a broader context for understanding the potential risks of treatment. This randomized, open-label, controlled clinical trial will enroll hospitalized patients aged 18 and older who require high-dose GC therapy (prednisone equivalents \>30 mg/day). The study will be conducted at the High Specialty Medical Unit, Hospital of Specialties No. 1, National Medical Center of Bajío, Mexican Institute of Social Security. Participants will be randomly assigned to one of two groups: the dapagliflozin group (10 mg/day) or the control group receiving standard glucose monitoring (SGM). Both groups will undergo routine glucose monitoring through capillary glucose checks (three times daily) and fasting central glucose assessments. The study will be conducted during the patients' hospitalization, and participants will be followed until discharge or up to 10 days, whichever occurs first. The dosing schedule for dapagliflozin will ensure it is administered synchronously with the GC dose (within 12 hours of GC administration). Additionally, data regarding the incidence of insulin therapy use, as well as the incidence and duration of hyperglycemic crises (defined as ≥2 persistent glucose readings ≥180 mg/dL within 24 hours), will be carefully recorded and analyzed. Adverse events will be monitored throughout the study, with particular attention to renal function, as SGLT2 inhibitors have been associated with potential renal side effects in some patient populations. The statistical analysis will be based on comparing the two treatment arms for the incidence of GIH using appropriate methods, including Chi-square tests for categorical variables and Kaplan-Meier survival analysis for cumulative hyperglycemia-free days. All analyses will be conducted with a significance level set at p \< 0.05, and SPSS v20 will be used for statistical processing. The findings from this study could provide critical insights into the potential role of dapagliflozin in preventing GIH in high-risk hospitalized patients, improving patient outcomes, and offering a new therapeutic strategy in managing hyperglycemia associated with glucocorticoid therapy.
Interventions
Participants will receive 10mg/day of dapagliflozin orally. The administration will occur within a synchronous range, meaning that the time difference between dapagliflozin administration and glucocorticoid administration should not exceed 12 hours.

Intervention model description
Protocol Design: Participants will be randomized 1:1, with group assignments known to all. Dapagliflozin (10 mg/day) will be administered orally within 12 hours of glucocorticoid dosing. Adherence will be ensured through patient/family training and nursing reports. Intervention Monitoring: Daily glucose levels will be assessed via preprandial capillary measurements (three shifts) and fasting central glucose (6-8 hours fasting). Standard glycemic monitoring (SGM) will also be performed. Definitions for Objectives: Hyperglycemia (HIG): ≥2 readings ≥140 mg/dL (7.8 mmol/L) in 24 hours. Hyperglycemic Crisis (HC): ≥2 readings ≥180 mg/dL (\>10 mmol/L) in 24 hours. If insulin or other antidiabetic treatments are initiated, they will be allowed alongside dapagliflozin in the intervention arm, with their use documented. Safety Monitoring: Adverse events will be recorded for all groups. Follow-up will continue until discharge, 10 days, or whichever occurs first.
