Predictors of early discontinuation of dapagliflozin versus other glucose-lowering medications: a retrospective multicenter real-world study

In routine clinical practice, early discontinuation of newly initiated glucose-lowering medications (GLM) is relatively common. We herein evaluated if the clinical characteristics associated with early discontinuation of dapagliflozin were different from those associated with early discontinuation of other GLM

Evaluation of metalloproteinase 2 and 9 levels and their inhibitors in diabetic and healthy subjects

OBJECTIVES: We hypothesized that molecules active in vascular remodeling (i.e. MMPs and their TIMPs) could be modified in diabetic patients, as indirect markers of the diabetes related generalized abnormality of vascular activity. To test this hypothesis, we measured the plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 in type 2 diabetic patients and in healthy subjects. METHODS: We enrolled 181 diabetic patients and 165 controls. We measured body mass index (BMI), glycosylated hemoglobin (HbA(1c)), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment index (HOMA index), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (Tg), lipoprotein(a) [Lp(a)], plasminogen activator inhibitor-1 (PAI-1), homocysteine (Hct) fibrinogen (Fg), high sensitivity C-reactive protein (hs-CRP), and plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2. RESULTS: A significant increase (P<0.0001) of BMI, HbA(1c), FPG, FPI, HOMA index, SBP, DBP, TC, LDL-C, Tg, Lp(a), PAI-1, Hct, Fg, and hs-CRP was present in the diabetic group, with a significant decrease (P<0.0001) of HDL-C levels compared to healthy subjects. MMP-2 and MMP-9 levels were significantly higher (P<0.0001) in diabetic patients. Significant TIMP-1, and TIMP-2 increase was also observed (P<0.0001) in the diabetic group. CONCLUSION: Plasma levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 are increased in diabetic patients which may reflect abnormal extracellular matrix (ECM) metabolis

Predictors of early discontinuation of dapagliflozin versus other glucose-lowering medications: a retrospective multicenter real-world study

Background and aims: In routine clinical practice, early discontinuation of newly initiated glucose-lowering medications (GLM) is relatively common. We herein evaluated if the clinical characteristics associated with early discontinuation of dapagliflozin were different from those associated with early discontinuation of other GLM. Methods: The DARWIN-T2D was a multicenter retrospective study conducted at diabetes specialist outpatient clinics in Italy. We included 2484 patients who were initiated on dapagliflozin in 2015\u20132016 and 14,801 patients who were initiated on other GLM (DPP-4 inhibitors, GLP-1 receptor agonists, or gliclazide) in the same period. After excluding patients who had not (yet) returned to follow-up, we compared the characteristics of patients who persisted on drug versus those who were no longer on drug at the first available follow-up after at least 3&nbsp;months. Results: As compared to those who persisted on drug, patients who discontinued dapagliflozin (51.7%) were more often female, had higher baseline fasting plasma glucose (FPG), HbA1c, and eGFR, and less common use of metformin. Upon multiple regression, higher HbA1c, higher eGFR, and lower metformin use remained independently associated with early discontinuation. Among patients who had been initiated on other GLM, 41.7% discontinued. Variables independently associated with discontinuation were older age, longer diabetes duration, higher HbA1c, eGFR, and albumin excretion, more common use of insulin and less metformin. Conclusion: In routine clinical practice, all variables associated with dapagliflozin discontinuation were also associated with discontinuation of other GLM. Thus, despite a distinctive mechanism of action and a peculiar tolerability profile, no specific predictor of dapagliflozin discontinuation was detected

Phenotyping normal kidney function in elderly patients with type 2 diabetes: a cross-sectional multicentre study

Aims: Type 2 diabetes (T2D) accelerates the decline in glomerular function; however, some individuals do not develop chronic kidney disease despite advanced age and long-lasting T2D. We aimed to phenotype patients with T2D aged 80&nbsp;years or older who presented with a fully preserved kidney function. Methods: From an Italian population of 281,217 T2D outpatients, we collected data on demographics, anthropometrics, diabetes duration, HbA1c, fasting plasma glucose, lipids, liver enzymes, estimated glomerular filtration rate (eGFR), albumin excretion rate (AER), chronic complications, and medication use. We primarily compared patients with a fully preserved kidney function (eGFR &gt; 90&nbsp;ml/min/1.73&nbsp;m2 and AER &lt; 30&nbsp;mg/24&nbsp;h, or G1A1) with those with mild kidney impairment (eGFR 60–90&nbsp;ml/min/1.73&nbsp;m2 and AER &lt; 30&nbsp;mg/24&nbsp;h, or G2A1). Results: N = 113,860 had available data for eGFR and AER, 21,648 of whom were aged ≥ 80. G1A1 (n = 278) and G2A1 (n = 6647) patients represented 1.3 and 30.7% of aged T2D patients, respectively, with an average diabetes duration of 16&nbsp;years. Differences between the G1A1 and G2A1 groups were entered in a multiple logistic regression analysis with and without imputation of missing data. After adjustment and in both imputed and non-imputed datasets, younger age, lower BMI and lower triglycerides were associated with fully preserved versus mildly impaired kidney function. The comparison between G1A1 and G1A2/3 yielded different results. Conclusions: In a rare population of patients with a fully preserved kidney function despite old age and long-lasting diabetes, lower BMI and triglycerides suggest that protection from lipotoxicity may preserve kidney function over time
