CAPTURE: A cross-sectional study on the prevalence of cardiovascular disease in adults with type 2 diabetes in Italy.

BACKGROUND AND AIMS: The prevalence of type 2 diabetes (T2D) in Italy is increasing and cardiovascular disease (CVD) represents the leading cause of death in this population. CAPTURE was a multinational, multicentre, non-interventional, cross-sectional study assessing the prevalence of CVD, atherosclerotic CVD (AsCVD) and CVD subtypes among patients with T2D, across 13 countries. Here we report the results from Italy. METHODS AND RESULTS: Overall, 816 patients with T2D (median age, 69 years [interquartile range: 62-75]; median duration of diabetes, 11.2 years [interquartile range: 5.7-18.7]) were recruited during routine clinical visits at secondary care centres in Italy between December 2018-September 2019. The prevalence of CVD was estimated at 38.8%, largely accounted for by AsCVD (33.1%). The most prevalent CVD subtype was coronary heart disease (20.8%), followed by carotid artery disease (13.2%). Most patients (85.9%) were prescribed oral glucose-lowering agents (GLAs), particularly biguanide (76.7%). Insulin use was higher in patients with CVD (41.3%) than in patients without CVD (32.9%). Sodium-glucose co-transporter-2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) were prescribed to 20.2% vs 14.6%, and 14.5% vs 16.6% of patients with CVD compared to those without CVD, respectively. CONCLUSION: The results show that, in Italy, more than one in three patients with T2D attending secondary care centres have CVD, 85% of whom have AsCVD, yet only a minority are treated with SGLT2is and GLP-1 RAs, in discordance with the recommendations of current national and international guidelines.

Long-Term Effectiveness of Liraglutide for Treatment of Type 2 Diabetes in a Real-Life Setting: A 24-Month, Multicenter, Non-interventional, Retrospective Study.

INTRODUCTION: The aim of the study was to evaluate whether the reduction in glycated hemoglobin (HbA1c) observed in clinical trials with liraglutide in type 2 diabetes (T2D) could be attained in routine clinical practice. METHODS: ReaL was a multicenter, non-interventional, observational, retrospective, longitudinal study on the effectiveness of liraglutide, a human glucagon-like peptide-1 analog, in individuals with T2D treated in daily practice in Italy. Between 26 March and 16 November 2015, data were taken from clinical records of patients aged ≥ 18 years with treatment follow-up data of up to 24 months and who received their first prescription of liraglutide in 2011. RESULTS: A total of 1723 patients were included in the analysis. At baseline, mean age was 58.9 years, duration of diabetes was 9.6 years, and HbA1c was 8.3%. At 12 months, 36.1% of patients were prescribed the maximum 1.8 mg dose; 43.5% [95% confidence interval (CI): 40.9; 46.2] of patients attained the primary outcome of a reduction in HbA1c of ≥ 1% point at 12 months. At 24 months, 40.9% (95% CI 38.1; 43.7) of patients had attained the HbA1c target of ≤ 7%. Additionally, body weight significantly decreased by 3.4 kg (95% CI - 3.6; - 3.1, p < 0.0001). CONCLUSION: In this observational study conducted in routine clinical practice for up to 2 years, treatment with liraglutide improved HbA1c and reduced body weight in a similar fashion to that observed under randomized clinical trial conditions. The data support the use of liraglutide as an effective treatment for T2D in clinical practice. FUNDING: Novo Nordisk S.p.A. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02255266.

Epidermal basement membrane alpha 5(IV) expression in females with Alport syndrome and severity of renal disease.

BACKGROUND: X-linked Alport syndrome is a progressive nephritis caused by mutations of the COL4A5 gene. This gene encodes the collagen alpha 5(IV) chain, which is abnormally distributed in the glomerular basement membrane (GBM) and epidermal basement membrane (EBM). It has been reported a negative correlation between alpha 5(IV) chain distribution in EBM and the degree of proteinuria in heterozygous females with Alport syndrome. METHODS: In the present study, we evaluated the distribution of the alpha 5(IV) chain in the EBM and the degree of proteinuria in 22 females with X-linked Alport syndrome. The distribution of the cutaneous alpha 5(IV) chain was measured by a confocal laser microscope using an anti-alpha 5(IV) monoclonal antibody. The expression ratio of alpha 5(IV) distribution was quantified dividing the extension of the positive signal and the maximal extension of the specimen. Urinary protein excretion was expressed as urinary protein over urinary creatinine ratio. RESULTS: Proteinuria was present in five of the 22 patients. In two patients with proteinuria, alpha 5(IV)chain was normally distributed; in the remaining three, the expression ratio of alpha 5(IV)chain was 35%, 47%, and 48%. Of the 17 patients without proteinuria, two displayed a complete absence of the alpha 5(IV) chain in EBM, five displayed a normal staining, and the remaining 10 had an expression ratio between 18% and 65%. CONCLUSION: Our data suggest that there is no correlation between the severity of the glomerular involvement (expressed by proteinuria) and the staining of the alpha 5 chain in the EBM in females with X-linked Alport syndrome.
