ABSTRACT

BACKGROUND Diabetes mellitus (DM) is associated with poor outcomes in acute stroke patients (ASPs). This study aims to determine the prevalence of NDDM in the ASPs and to compare the outcome in NDDM and previously diagnosed DM (PDDM) in Cameroon. METHODS AND MATERIALS This was a hospital-based prospective cohort study that included ASPs with NDDM and PDDM. Outcome data were collected within 3 months of stroke onset. Chi-square and t tests were used for comparisons, whereas survival analysis was performed using Cox regression and Kaplan-Meier analysis. RESULTS Of the 701 ASPs included, 24.8% had PDDM (n = 174) and 9.4% NDDM (n = 66). NDDM had a higher mortality rate on admission and 3 months after stroke (P < .05). PDDM were more likely to survive within 3 months after stroke onset (log-rank test P  = .008). The risk of dying among NDDM was increased (adjusted hazard ratio = 1.809; 95% confidence interval: 1.1532.839; P  = .010). NDDM were more likely to have higher mean National Institutes of Health Stroke Scale and modified Rankin score (P  < .05) on admission. PDDM were more likely to develop urinary tract infections during hospitalization (P  = .015). There was no significant difference between functional outcome on admission and 3 months after stroke (P  > .05). CONCLUSION NDDM are associated with increased mortality and are more likely to have poorer functional outcomes and more severe stroke than those with PDDM.
