Objective To identify the best therapy regimen for a patient with rare hypoglycemia due to insulin autoantibody (IAA). Methods We searched The Cochrane Library (Issue 3, 2008), PubMed (1966-July 2009), EMbase (1974-July 2009) and CBM (1978-July 2009) to identify relevant evidence. The quality of the retrieved studies was critically assessed. Results A total of 291 records were retrieved. No clinical guidelines, systematic reviews or clinical randomized studies were identified. Thirty treatment-related studies involving 6 interventions showed that insulin combined with Prednisone was relatively more effective and safer than conventional therapies. Conclusion The steroid treatment might be useful for the improvement of glycamic control in patients with high IAA levels and severe hypoglycemia and hyperglycemia due to insulin antibodies raised against subcutaneously-injected human insulin.
Objective To evaluate the accuracy of newer-generation home blood glucose meter (Accu-Check? Integra) in patients with impaired glucose regulation (IGR) and newly-diagnosed type 2 diabetes mellitus. Methods A cross-sectional study was performed on 109 cases with newly-diagnosed type 2 diabetes or IGR who were asked to take oral glucose tolerance test (OGTT), while paired samples, that were Accu-Check? Integra in capillary blood glucose (CBG) and laboratory glucose in venous plasma glucose (VPG ), were taken simultaneously. Taking VPG as the reference value, the accuracy of the home glucose meter was assessed according to the international standardization organization (ISO), including, the accuracy was studied by means of Median absolute difference (Median AD) and Median absolute relative difference (Median RAD), the consistency of CBG and VPG was studied by Clarke Error Grid analysis, the correlation of CBG and VPG was analyzed according to liner regression analysis, and the sensitivity and specificity for hyperglycemia were also calculated. Results There were 292 VPG values paired with CBG values, among which 93.49% of CBG values met ISO home glucose meter criteria, the median AD was 7.2 mg/dL, and the median RAD was 4.76%. Paired glucose measurements from the Accu-Check Integra meter and laboratory glucose measurement demonstrated that 100% of paired points in the overall subject population fell in zones A and B of the Clarke Error Grid. The CBG value was well correlated to VPG value in the overall level, and the sensitivity and specificity were 94.6% and 95.7% respectively for hyperglycemia. Conclusion The newer-generation home blood glucose meter (Accu-Check? Integra) demonstrates a high degree of accuracy, and it can precisely report the real value of blood glucose.
