Ketone bodies (acetoacetate, acetone, and b-hydroxybutyrate [bOHB]) are metabolites that are well known as alternative energy sources. The ketone bodies become important under certain conditions as they can supplement energy to cells when glucose oxidation dramatically decreases. They accumulate in the plasma under conditions of fasting and uncontrolled diabetes. Though ketone bodies serve as substrates for energy, several deleterious effects of the accumulation of these moieties have been reported. Derangements of ketone body metabolism occur in numerous disease states, including types 1 and 2 diabetes and heart failure, and ketone body metabolism changes over the course of normal aging. Ketoacidosis occurs after the accumulation of ketone bodies, which can be detected by urine test as early sign. However, there is limited research on urine ketone bodies in the acute phase of ischemic stroke.
This study enrolled 14 015 patients with AIS or TIA who screened for urine ketone bodies from the Third China National Stroke Registry. Status of urine ketone bodies were classified into negative, suspicious positive and positive. The outcomes were all-cause death and poor functional outcomes (modified Rankin Scale [mRS] 2e6/3-6) at 3 months and 1 year. Multivariable Cox proportional hazards regressions and logistic regressions were adopted to explore the associations.
Positive urine ketone bodies can independently predict all-cause death and poor functional outcomes in patients with AIS or TIA
Participants with negative, suspicious positive and positive urine ketone bodies were 12979 (92.61%), 480 (3.42%) and 556 (3.97%). After multivariate adjustment, patients with positive urine ketone bodies had a higher risk of all-cause death (hazard ratio, 1.74; confidence interval [CI], 1.07e2.83), a higher proportion of mRS score 2e6 (Odds ratio [OR], 1.85; 95% CI, 1.51e2.27), mRS score 3e6 (OR, 2.00; 95% CI, 1.61e2.48) at 3 months, compared to those with negative urine ketone bodies. Significant associations persisted at 1 year. Furthermore, there was no significant interaction of diabetes status and alcohol use with urine ketone bodies
