The importance of postprandial plasma glucose (PPG) in patients with Type 2 diabetes

Posted on: 02 Oct 12

Postprandial plasma glucose (PPG) is acknowledged by seven in 10 diabetes specialists (70%) as being equally important as fasting plasma glucose (FPG) for achieving HbA1c goals, in patients with Type 2 diabetes mellitus[i]

  • 80% of diabetes specialists suggest there is a need for new treatments which more specifically address elevated PPG concentrations, leading to optimal glycaemic controli
  • Three quarters (75%) of those surveyed think that monitoring of PPG levels should be introduced into diabetes clinicsi
  • Six in 10 (60%) state they are unaware of any guidelines relating to the monitoring of PPGi
Guildford, UK, 2nd October 2012 - A new survey commissioned by Sanofi Diabetes reveals that seven in 10 (70%) diabetes specialists believe that postprandial plasma glucose (PPG) is as important as fasting plasma glucose (FPG) in the management of Type 2 diabetes mellitus (T2DM) for achieving target glycated haemoglobin (HbA1c) levelsi. In addition, 80% of those surveyed suggest there is a need for new treatments that address elevated PPG concentrations, leading to optimal glycaemic controli. These survey findings are released as new data for Lyxumia® (lixisenatide) is announced by Sanofi at the Annual Meeting of the European Association for the Study of Diabetes (EASD) 2012.

Achieving optimal blood glucose control is the cornerstone of the management of T2DM as this reduces the likelihood of diabetes complications such as heart disease, stroke, retinopathy, neuropathy and nephropathy[ii]. There is established consensus on fasting plasma glucose (FPG) as a target for reducing a patient’s HbA1c. However, growing evidence supports the importance of also reducing PPG for achieving ideal HbA1c levels and reducing cardiovascular disease risk for certain groups of patientsii,[iii],[iv],[v].

In a recent study, a significant proportion (40%) of patients with T2DM treated with basal insulin and oral antidiabetic drug (OAD) therapy achieved FPG but not HbA1c targetsiv. This implies that PPG may be under-recognised and under-treated as a contributing factor to overall blood glucose control. As a result of this, these patients need additional treatments that control postprandial peaks, in addition to basal insulin, in order to achieve their HbA1c goal. The evidence suggests that whilst FPG is a key focus in the initial management of those with poor glycaemic control, PPG should also be targeted for optimal glycaemic control[vi].

This concept is supported by the International Diabetes Federation (IDF) Guideline for the Management of Postmeal Glucose, which outlines in detail the significant risk posed by postprandial hyperglycaemia ii.

This latest survey, conducted with over 300 diabetes specialists (100 endocrinologists, 100 diabetologists and 100 diabetes specialist nurses)i, was commissioned in light of the ongoing debate amongst healthcare professionals regarding the role of PPG (the term used to define plasma glucose concentrations after eating[vii]) in the overall management of T2DM.

Nearly all respondents (97%) stated that tighter overall glycaemic control is important in the management of T2DM, with 99% appreciating that it achieves better outcomes for patientsi. Three quarters (75%) of those surveyed suggest that monitoring of PPG levels should be introduced into diabetes clinicsi.

Dr Mike Baxter, Consultant Diabetologist and Endocrinologist at the Runnymede Hospital and Consultant Advisor at Sanofi Diabetes said: “The results of this survey support the growing body of evidence highlighting the importance of controlling PPG levels as a key part of the management of some patients with Type 2 diabetes, particularly those in whom intensive diabetic control has been highlighted as a priority in their individualised care plan.”

Six in 10 (60%) diabetes specialists surveyed state they are unaware of any guidelines relating to the monitoring of PPG as part of the management of T2DMi. The findings call for an improvement in the awareness of guidance relating to the monitoring of PPG as part of the overall management of the conditioni.

Professor David Owens, Emeritus Professor at Cardiff University, Institute of Molecular and Experimental Medicine, who was member of the IDF Guideline Development Group commented: “Whilst there is certainly a growing awareness of the importance of measuring PPG amongst healthcare professionals, it is clear that there needs to be more awareness and uptake of the recent IDF Guideline for the Management of Postmeal Glucose (2011) as well as the development of a UK specific version of the guideline. We also need to ensure that persons with diabetes are educated about PPG self-monitoring and recognise its importance as part of the routine management of their condition.”

The results of this survey coincide with positive new data on lixisenatide announced by Sanofi at the EASD Annual Meeting 2012. The study found that once-daily lixisenatide injected subcutaneously in the morning significantly delayed gastric emptying, with a significant impact on PPG and blood glucose levels throughout the day, contributing to overall glycaemic control[viii].

The 28-day, randomised, double-blind, placebo-controlled, parallel-group study in patients with T2DM (lixisenatide n=19; placebo n=22) demonstrated that a final dose of once-daily 20 µg lixisenatide in the morning (after titrating from 5–20 µg with 2.5 µg increments every 4 days), in addition to up to two oral anti-diabetic agents, had a significant delay on the rate of gastric emptying compared with placebo, which improved the blood glucose levels throughout the day8. At day 28, PPG was significantly reduced after a standardised breakfast (p
