ABSTRACT

AIMS: To assess perceptions of patients using subcutaneous insulin infusion (CSII) about metabolic control, pump malfunctions, technical and insertion site adverse events (AEs) related to infusion sets/catheters as well as patients' practices. METHODS: Online survey (from June 2016 to January 2017) using an actualized 39-item questionnaire directed to adults with type 1 diabetes (T1D) using CSII therapy and living in the province of Quebec, Canada. RESULTS: Participants with T1D (n = 115, 72% females, 39.7 ±â€¯14.0 years, diabetes duration: 20.9 ±â€¯12.2 years, CSII use: 6.2 ±â€¯4.1 years) adequately completed the survey. Infusion sets were changed every 3.3 ±â€¯0.9 day. Improved glucose control and decreased number/severity of hypoglycemic episodes were reported by 80% and 68%/50% of subjects, respectively. Over the past year of CSII use, participants perceived no increase in anxiety/worry (84%), no negative impact on life (89%) or on time off from work/school (82%). Conversely, many experienced at least one clinical AEs at insertion site [pain (84%), adhesion (76%), irritation (69%), lipodystrophy (45%)] and technical issues [blockage (52%), cannula kinking (50%), pump stop (55%), air bubbles (46%)]. No significant association was observed between catheter wear-time and AEs. All participants had one or more problems related to CSII use, although only 37% reported addressing these issues with health professionals. CONCLUSION: Our study suggests that patients positively perceived CSII use although they experienced a high frequency of clinical and technical AEs. This warrants further attention by health professionals, investigators and manufacturers to optimize CSII therapy.

ABSTRACT

The reactive dicarbonyls, glyoxal and methylglyoxal (MG), increase in diabetes and may participate in the development of diabetic complications. Glyoxal and MG are detoxified by the sequential activities of glyoxalase 1 (GLO1) and glyoxalase 2. To determine the contribution of these dicarbonyls to the etiology of complications, we have genetically manipulated GLO1 levels in apolipoprotein E-null (Apoe(-/-)) mice. Male Apoe(-/-) mice, hemizygous for a human GLO1 transgene (GLO1TGApoe(-/-) mice) or male nontransgenic Apoe(-/-) litter mates were injected with streptozotocin or vehicle and 6 or 20 weeks later, aortic atherosclerosis was quantified. The GLO1 transgene lessened streptozotocin (STZ)-induced increases in immunoreactive hydroimidazolone (MG-H1). Compared to nondiabetic mice, STZ-treated GLO1TGApoe(-/-) and Apoe(-/-) mice had increased serum cholesterol and triglycerides and increased atherosclerosis at both times after diabetes induction. While the increased GLO1 activity in the GLO1TGApoe(-/-) mice failed to protect against diabetic atherosclerosis, it lessened glomerular mesangial expansion, prevented albuminuria and lowered renal levels of dicarbonyls and protein glycation adducts. Aortic atherosclerosis was also quantified in 22-week-old, male normoglycemic Glo1 knockdown mice on an Apoe(-/-) background (Glo1KDApoe(-/-) mice), an age at which Glo1KD mice exhibit albuminuria and renal pathology similar to that of diabetic mice. In spite of ~75% decrease in GLO1 activity and increased aortic MG-H1, the Glo1KDApoe(-/-) mice did not show increased atherosclerosis compared to age-matched Apoe(-/-) mice. Thus, manipulation of GLO1 activity does not affect the development of early aortic atherosclerosis in Apoe(-/-) mice but can dictate the onset of kidney disease independently of blood glucose levels.
