insulin-glargine and Edema

Both insulin and thiazolidinediones (TZDs) are effective in the treatment of hyperglycaemia and amelioration of insulin resistance in type 2 diabetes but have side effects including weight gain and fluid retention. The use of TZDs has been further hampered by the risk of adverse cardiovascular events including heart failure. The present study evaluated the effect of pioglitazone or insulin glargine on cardiac function and size as well as on surrogate markers of fluid retention such as weight, haemoglobin and natriuretic peptides.. Thirty patients with inadequate glycaemic control on metformin and sulfonylurea were randomised to receive add-on therapy with insulin glargine or pioglitazone for 26 weeks. Echocardiographic data and blood samples were collected from the two groups before the start of the treatment and after 26 weeks. Left ventricular end-diastolic and left atrial end-systolic volumes were quantified, weight measured and blood samples analyzed.. After 26 weeks of treatment, the changes in HbA1c, weight and haemoglobin were similar between the two groups. HDL increased significantly in the pioglitazone group. While there was an increase in natriuretic peptides in the pioglitazone group (NT-proBNP 11.4 +/- 19.6 to 22.8 +/- 44.0, p = 0.046), the difference between the treatment groups was not significant. Left ventricular end-diastolic volume increased by 11% and left atrial end-systolic volume by 17% in the pioglitazone group (Both, p < 0.05, between treatment groups). There was a borderline significant increase in ejection fraction in the pioglitazone group.. This randomised pilot-study showed that six-month treatment with pioglitazone induced significant increases in natriuretic peptides and alterations of cardiac size. These changes were not observed with insulin glargine, which also is known to induce fluid retention. Larger randomised trials are warranted to confirm these findings.

This treat-to-target study compared the efficacy and safety of insulin detemir (IDet) and insulin glargine (IGla) in a basal-bolus (insulin aspart) regimen in type 2 diabetes.. 385 patients were randomized 2 : 1 (IDet : IGla). Non-inferiority of IDet to IGla was determined by HbA(1c) 95% CI upper limit <0.4.. IDet and IGla showed similar efficacy in HbA(1c) reduction at 26 weeks, as the non-inferiority criterion was met at 26 weeks (LS mean [Det-Gla]: 0.207; 95% CI: 0.0149,0.3995). It appeared that IGla in some cases did better than IDet in terms of HbA(1c), but the difference (0.207%) was not clinically meaningful. Based on the CONSORT guideline, non-inferiority analysis using the LOCF approach was inconclusive regarding possible inferiority of delta 0.4 (LS mean of [Det-Gla]: 0.307; 95% CI: 0.1023, 0.5109). HbA(1c) decreased significantly from baseline in IDet (-1.1% [26 weeks], -0.9% [LOCF], p < 0.001) and in IGla (-1.3% [26 weeks, LOCF], p < 0.001). Final HbA(1c) were 7.1% (26 weeks) and 7.3% (LOCF) in IDet, and 6.9% (26 weeks) and 7.0% (LOCF) in IGla. Final FPG were 130 mg/dL (26 weeks) and 135 mg/dL (LOCF) in IDet, and 134 mg/dL (26 weeks) and 137 mg/dL (LOCF) in IGla. There was significantly less weight gain in IDet-treated patients (1.2 +/- 3.96 kg versus 2.7 +/- 3.94 kg, p = 0.001). Hypoglycemia risk was comparable between groups. The majority of IDet-treated patients (87.4%) remained on a once-daily basal insulin regimen throughout the study.. IDet and IGla were both effective and safe treatments for glycemic control in a basal-bolus regimen for type 2 diabetes. Clinically significant reductions in HbA(1c) were achieved in both groups, but with significantly less weight gain in the IDet group at comparable basal insulin dosage.

We report a case of generalised insulin oedema after intensification of treatment with genetically modified insulin. This is the first case of generalised oedema in response to treatment with insulin analogues in a patient not insulin naive.
