DECIST: Dapagliflozin Effect in Cognitive Impairment in Stroke Trial
Study Details
Study Description
Brief Summary
Background: Dementia is an international public health problem, affecting approximately 50,000,000 people worldwide in 2018 and will triple by 2050; furthermore, reaching an approximate cost of 4 billion dollars. Given its high worldwide prevalence and probable underdiagnosis, the international guidelines for the assessment of dementia syndromes recommend the assessment of cognitive impairment in patients over 55 years of age as part of clinical practice in patients who presented an ischemic cerebrovascular event. Several risk factors associated with cognitive impairment in cerebrovascular disease are identified in the literature: 1) demographic factors (e.g., age over 65 years and female sex); 2) risk factors present prior to the ischemic stroke (e.g., cognitive impairment, physical impairment); 3) factors utilized to assess the severity of an ischemic stroke (e.g., supratentorial location, ischemic stroke in the dominant hemisphere, recurrence of ischemic strokes); 4) post-ischemic stroke factors (e.g., delirium and seizures); and 5) factors associated with neuroimaging findings (e.g., cerebral small vessel disease, cortical atrophy, and medial temporal lobe atrophy).
This is a randomized controlled trial in individuals with an acute ischemic stroke without dementia that will be treated with 10mg dapagliflozin PO q24h for 12 months and standard treatment against only standard treatment (i.e., statins, platelet antiaggregant, and hypoglycemic medications) when appropriate. The outcome measure evaluated will be global cognitive function. Cardiovascular risk factors will be associated with cognitive decline.

Detailed Description
Detailed Description: This is a double-blind, randomized, placebo-controlled, parallel-group, 12-month longitudinal study performed at a single center (Hospital General de Zona con Medicina Familiar IMSS No. 21, León Guanajuato, México) designed to investigate the effect of dapagliflozin in participants with a recent acute stroke but no history of dementia (CDR score ≤ 0.5). A total of 270 participants are to be included (i.e., 135 on each arm).
Overall objective: To assess the effect of Dapagliflozin on cardiovascular risk (i.e., the volume of epicardial fat, volume of total carotid atherosclerotic plaque, and coronary artery calcium score) in patients with ischemic cerebrovascular disease dependent on global cognitive function at a second level teaching hospital in Mexico.
Statistical analysis: Descriptive statistics will be reported for all included variables. Statistical analysis will be performed using SPSS 25 (SPSS Inc., Chicago, IL). All variables will be examined to determine the existence of outliers and whether they meet the assumptions about a Gaussian distribution. The Shapiro-Wilk tests will be used to determine normality distribution, as well as visual inspection of histograms and Q-Q plots. Demographic and clinical variables will be summarized in proportions and percentages. The categorical variables will be evaluated to determine statistical inferences with the Mann-Whitney U test. Continuous variables will be assessed for statistical inferences using t-tests (e.g., simple, paired, one, and two samples) and Levene's test to assess equality of variances. The Kaplan-Meier method will be used to calculate the distributions of mortality and development of mild amnestic cognitive disorder and dementia syndrome. The Gehan-Breslow-Wilcoxon method will be used to assess the equality of the mortality distributions and the development of mild amnestic cognitive disorder or dementia syndrome. A multivariate analysis will be performed with a Cox regression model to assess the variables that predict mortality, and the development of a mild amnestic cognitive disorder, or dementia syndrome at 6 and 12 months in case there are differences in mortality distributions. Statistical significance will be set at p=0.05 and a Bonferroni correction will be performed for multiple comparisons.
