title: Self-titration of biphasic insulin aspart 30/70 improves glycaemic control and allows easy intensification in a Dutch clinical practice.
abstract: OBJECTIVE
  This 18-month study assessed the improvement in glycaemic control and proportion of patients reaching glycated haemoglobin (HbA(1c)) targets with biphasic insulin aspart 30/70 (BIAsp 30) in clinical practice.
  
  
  METHODS
  Type-2 diabetes patients failing on oral antidiabetic drugs (n=90) or existing insulin regimens (n=59) started or switched to BIAsp 30. Thiazolidinediones were stopped, metformin was continued. BIAsp 30 was given once daily (n=41), twice daily (n=96), or three times daily (n=12). Patients were taught self-monitoring and self-titration using an algorithm, adding daily doses of BIAsp 30 when necessary.
  
  
  RESULTS
  Mean baseline HbA(1c) was 8.4%, weight 85.4 kg, and age 57.9 years. All patients experienced significant reductions in HbA(1c) (mean 1.9%+/-0.1), fasting plasma glucose (mean 2.8 mmol/l), and post-prandial glycaemia (mean 2.9 mmol/l); 91% of patients achieved HbA(1c)<7% and 52% achieved HbA(1c) < or=6.5%. No major or nocturnal hypoglycaemia were reported; 15% of patients reported minor hypoglycaemia. Insulin-naïve patients gained mean 2.7 kg; patients who switched from another insulin lost weight (mean -0.6kg).
  
  
  CONCLUSIONS
  The results from this study from routine care suggest that BIAsp 30 may allow a large proportion of type-2 diabetes patients (90%) to improve glycaemic control and reach target HbA(1c)<7%, using self-titration.
