Prognostic Signification of Admission Hyperglycemia among Acute Stroke Patients in Intensive Care Units in Kinshasa,the Democratic Republic of the Congo

BACKGROUND AND AIM: Although admission hyperglycemia has been reported to be associated with unfavorable outcomes in acute stroke, little is known about this association in sub-Saharan Africa. Therefore, the aim of the present study was to assess the prognostic significance of admission hyperglycemia in the acute phase of stroke in Congolese patients. METHODS: In a multicenter prospective cohort study, consecutive patients with acute stroke were examined in 5 Emergency Rooms or Intensive Care Units of Kinshasa between July 15th, 2017 and March 15th, 2018. The severity of stroke was assessed at admission using the Glasgow Coma Scale. Stress hyperglycemia was defined as random blood glucose levels at admission > 140 mg/dL in patients without known type 2 diabetes mellitus (T2DM). The endpoint was 10-day all-cause in-hospital mortality. Survival (time-to-death) curves were built using the Kaplan Meier methods. Cox proportional analysis was used to identify predictors of 10-day all-cause in-hospital mortality. The predictive performance of blood glucose level to predict 10-day all-cause in-hospital mortality was assessed using ROC curve analysis. RESULTS: Out of 194 patients (mean age 58.7 ± 13.1 years;64% males, 74.7% light to moderate stroke severity;63.4% ischemic stroke) enrolled, 106 (54.6%) had admission hyperglycemia with 77 (72.6%) having stress hyperglycemia. Ninety four deaths (48.5%);mortality rate of 6 deaths per 100 person-days (95%CI 2.7 - 9.3) occurred during a median follow up time 6 (5 - 7) days equivalent to 1542 person-days. Independent predictors of 10-day all-cause in-hospital mortality were admission hyperglycemia regardless of diabetes status (aHR 3.77;95%CI 1.92 - 7.42;p < 0.001), GCS - 5.23;p = 0.001) and non-use of mechanical ventilation (aHR 1.97;95%CI 1.05 - 3.70;p = 0.034). Blood glucose concentrations (AUC 0.743;95%CI 0.672 - 0.814) had a better predictive performance for 10-day all-cause in-hospital mortality with an optimal value of 154 mg/dL (sensitivity 76.6% and specificity 70%). CONCLUSION: More than half of critically ill stroke patients exhibit admission hyperglycemia that impacts negatively on their survival in the acute phase highlighting thus the need for a better blood glucose control to improve outcomes.

Early Hyperglycemia in Diabetics as a Predictor of Disease Severity in COVID-19

Background: Hyperglycemia is an important predictor of prolonged hospitalization and mortality. The objective of this study was to analyze the role of early hyperglycemia in predicting the severity of COVID-19 illness and mortality. Method: Retrospective study on 259 patients with COVID-19 with measurement of average glucose during 24 hours of admission. Association of Early Hyperglycemia categorized as <180 mg/dl or >180 mg/dl;was studied with mortality, requirement of ICU stay and prognostic markers. Results: Early hyperglycemia (>180 mg/dl) revealed a higher median value for CRP (109 mg/l [IQR;48 - 199]) in comparison to <180 mg/dl group (86 mg/l [IQR;26.3 - 153]) p = 0.03. ICU stay was higher in >180 mg/dl group;24 (15.9%) vs 14 patients (13%) [p = 0.51] in the <180 mg/dl group. Mortality in the group > 180 mg/dl was 8 (5.3%) while <180 mg/dl had a mortality rate of 4 (3.7%) [p = 0.547]. Conclusion: Hyperglycemia in the first 24 hours may anticipate an increased risk of ICU stay and a higher mortality rate. It may be a possible predictor of disease severity.

Impact of admission blood glucose levels on prognosis of elderly patients with ST elevation myocardial infarction treated by primary percutaneous coronary intervention

OBJECTIVE:Admission hyperglycemia in acute myocardial infarction (MI) is related with increased in-hospital and long term mortality and major cardiac adverse events。 We aimed to investigate how admission hyperglycemia affects the short and long term outcomes in elderly patients >65 years) after primary percutaneous coronary intervention for ST elevation myocardial infarction。 METHODS:We retrospectively analyzed 677 consecutive elderly patients (mean age 72.2 ±5.4)。 Patients were divided into two groups according to admission blood glucose levels。 Group : low glucose group (LLG), glucose < 168 mg/dL; and Group 2: high glucose group (HGG), glucose >168 mg/dL。 RESULTS:In-hospital, long term mortality and in-hospital major adverse cardiac events were higher in the high admission blood glucose group (P <0.001)。 Multivariate regression analysis showed: Killip > 1, post-thrombolysis in MI <3 and admission blood glucose levels were independent predictors of in-hospital adverse cardiac events (P <0.001)。 CONCLUSIONS:Admission hyperglycemia in elderly patients presented with ST elevation myocardial infarction is an independent predictor of in-hospital major adverse cardiac events and is associated with in-hospital and long term mortality。
