    Gestational diabetes: fasting capillary glucose as a screening test in a multi-ethnic, high-risk population

    DIABETIC MEDICINE, Issue 8 2009
    M. M. Agarwal
    Abstract Aims, In populations at high risk of gestational diabetes mellitus (GDM), screening every pregnant woman by an oral glucose tolerance test (OGTT) is very demanding. The aim of this study was to determine the value of the fasting capillary glucose (FCG) as a screening test for GDM. Methods, FCG was measured by a plasma-correlated glucometer in 1465 pregnant women who underwent a one-step diagnostic 75-g OGTT for universal screening of GDM. Results, One hundred and ninety-six (13.4%) women had GDM as defined by the criteria of the American Diabetes Association. The area under the receiver operating characteristic curve (AUC) of the FCG was 0.83 (95% confidence interval 0.80,0.86). A FCG threshold of 4.7 mmol/l (at an acceptable sensitivity of 86.0%) independently could rule-out GDM in 731 (49.9%) women, while the FCG could rule-in GDM (100% specificity) in 16 (1.1%) additional women; therefore, approximately half of the women would not need to continue with the cumbersome OGTT. Conclusions, Screening using a FCG significantly reduces the number of OGTTs needed for the diagnosis of GDM. Wider assessment, particularly in low-risk populations, would confirm the potential value of the FCG as a screening test for GDM. [source]

    Continuous glucose monitoring system: an attractive support tool in diabetes education

    Abstract The study was designed to determine the usefulness of the CGMS (continuous glucose monitoring system) as a support tool in type 1 diabetes education. The CGMS is a sensor system that measures interstitial glucose levels every five minutes for three or more days, by means of a microelectrode inserted in the subcutaneous tissue. People with type 1 diabetes (n=52), who actively participated in diabetes self-management programmes, were monitored with CGMS during three to five days. Patients were selected for CGMS when unsatisfied with the glycaemic results achieved, given the effort made. Ten patients used CSII, 14 used insulin glargine plus rapid acting insulin analogue and 28 used NPH insulin plus short acting insulin. All patients used blood glucose self-monitoring, with a mean of 6.5±1.4 glucose readings per day. The CGMS register was evaluated with the patient. Mean capillary glucose during the 15 days prior to CGMS, mean capillary glucose during CGMS and mean capillary glucose during the 15 days after CGMS are compared. Discussion of the record with the patient frequently allowed detection of inappropriate solving attitudes. Mean capillary glucose dropped from 155±20mg/dL (8.60±1.11mmol/L) prior to CGMS to 143±20mg/dL (7.94±1.11mmol/L) after CGMS (p=0.000). The effectiveness of CGMS (number of patients in whom mean glucose improved) rose from 66.7% in 2001 to 70.6% in 2002, 78.9% in 2003 and 88.8% in 2004. When the patient is involved in the analysis of glucose fluctuations, CGMS is a useful tool in diabetes education that will help achieve attitude changes because of the evidence depicted by the continuous glucose record. Experience in the use of this tool by the professional will improve its effectiveness. Copyright © 2005 FEND. [source]

    Point-of-care Glucose and Hemoglobin A1c in Emergency Department Patients without Known Diabetes: Implications for Opportunistic Screening

    ACADEMIC EMERGENCY MEDICINE, Issue 12 2008

    Abstract Objectives:, The objectives were to evaluate the correlation between random glucose and hemoglobin A1c (HbA1c) in emergency department (ED) patients without known diabetes and to determine the ability of diabetes screening in the ED to predict outpatient diabetes. Methods:, This was a cross-sectional study at an urban academic ED. The authors enrolled consecutive adult patients without known diabetes during eight 24-hour periods. Point-of-care (POC) random capillary glucose and HbA1c levels were tested, as well as laboratory HbA1c in a subset of patients. Participants with HbA1c , 6.1% were scheduled for oral glucose tolerance test (OGTT). Results:, The 265 enrolled patients were 47% female and 80% white, with a median age of 42 years. Median glucose and HbA1c levels were 93 mg/dL (interquartile range [IQR] = 82,108) and 5.8% (IQR = 5.5,6.2), respectively. The correlation between POC and laboratory HbA1c was r = 0.96, with mean difference 0.33% (95% confidence interval [CI] = 0.27% to 0.39%). Glucose threshold , 120 mg/dL had 89% specificity and 26% sensitivity for predicting the 76 (29%) patients with abnormal HbA1c; , 140 mg/dL had 98% specificity and 14% sensitivity. The correlation between random glucose and HbA1c was moderate (r = 0.60) and was affected by age, gender, prandial status, corticosteroid use, and current injury. Only 38% of participants with abnormal HbA1c returned for OGTTs; 38% had diabetes, 34% had impaired fasting glucose/impaired glucose tolerance, and 28% had normal glucose tolerance. Conclusions:, ED patients have a high prevalence of undiagnosed diabetes. Although screening with POC random glucose and HbA1c is promising, improvement in follow-up with confirmatory testing and initiation of treatment is needed before opportunistic ED screening can be recommended.

    Fasting capillary glucose as a screening test for gestational diabetes mellitus

    Objective, To evaluate fasting capillary glucose as a screening test for gestational diabetes mellitus (GDM) compared with traditional risk factors and repeated random capillary glucose measurements. Design, Cross-sectional, population-based study. Setting, Maternal Health Care Clinics in Örebro County, Sweden. Population, An unselected population of women without diabetes. Methods, Fasting capillary glucose levels were measured at gestational weeks 28,32. Random capillary glucose levels were measured four to six times during pregnancy. Traditional risk factors for GDM were registered. GDM was diagnosed using a 75-g oral glucose tolerance test. Main outcome measures, Sensitivity, specificity, likelihood ratios. Results, In 55 of 3616 women participating in the study, GDM was diagnosed before 34 weeks of gestation. For fasting capillary glucose cutoff values between 4.0 and 5.0 mmol/l, sensitivity was in the range between 87 and 47% and specificity between 51 and 96%. Using a combined screening model of traditional risk factors with fasting capillary glucose at various cutoff values increased the sensitivity only slightly compared with using fasting capillary glucose alone. Conclusion, In this Swedish, unselected, low-risk population, fasting capillary glucose measurements were found to be an acceptable and useful screening test for GDM. [source]
