Insulin resistance and acute coronary syndrome
2010
BACKGROUND: Insulin resistance (IR), which can be quantified by HOMA index (fasting glucose X fasting insulin/22.5), is considered the "primum movens" for the development of Metabolic Syndrome. Many authors have suggested that insulin resistance could raise both incidence and mortality of coronary heart disease (CHD). IR is also associated with important predictors of cardiovascular disease, as increased concentration of LDL or triglyceride, decreased concentration of HDL, high systolic blood pressure, visceral obesity. There is accumulating evidence that chronic sub-clinical inflammation, as measured by inflammatory markers as C-reactive protein (CRP) and fibrinogen, is related with insuli…
Combined therapy with insulin and growth hormone in 17 patients with type-1 diabetes and growth disorders.
2013
<b><i>Background/Aim:</i></b> Combined growth hormone (GH) and insulin therapy is rarely prescribed by pediatric endocrinologists. We investigated the attitude of Italian physicians to prescribing that therapy in the case of short stature and type-1 diabetes (T1DM). <b><i>Methods:</i></b> A questionnaire was sent and if a patient was identified, data on growth and diabetes management were collected. <b><i>Results:</i></b> Data from 42 centers (84%) were obtained. Of these, 29 centers reported that the use of combined therapy was usually avoided. A total of 17 patients were treated in 13 centers (GH was started before T1…
Predictors of microvascular complications in type 1 diabetic patients at onset: The role of metabolic memory
2011
Background Several epidemiological studies showed a close association between metabolic control and microvascular complications in type 1 Diabetes Mellitus (T1DM). The aim of our longitudinal observational study was to evaluate the predictive role of the main clinical and biochemical parameters in determining microvascular complications. Methods 376 T1DM patients, hospitalized in our division from 1991 to 2005 (mean follow-up = 10.93 ± 4.26 years) were studied. Stepwise Cox regression analysis was used to identify the influence of residual ß-cell function, ß-cell autoimmunity, HbA1c levels and other clinical and laboratory parameters in the development of microalbuminuria and retinopathy. R…
ATP4A autoimmunity in pediatric patients with type 1 diabetes and its relationship to blood count, iron metabolism, and vitamin B12
2017
Objective We aimed to assess the prevalence of autoantibodies against the 4A subunit of the gastric proton pump (ATP4A) in pediatric type 1 diabetes (T1D) patients and explore the relationship between ATP4A positivity and blood cell count, iron turnover, and vitamin B12 concentration. Subjects The study included 94 (59% female) T1D children (aged 12.5 ± 4.1 years, T1D duration 4.2 ± 3.6 years, HbA1c 7.3 ± 1.5% (57 ± 12.6 mmol/mol) with no other autoimmune diseases. Methods ATP4A antibodies were measured in T1D patients using a radioimmunoprecipitation assay. Blood cell count, iron concentration, total iron binding capacity, ferritin, transferrin, hepcidin, and vitamin B12 concentration were…
Effects of experimental type 1 diabetes and exercise training on angiogenic gene expression and capillarization in skeletal muscle.
2006
Diabetes alters microvascular structure and function and is a major risk factor for cardiovascular diseases. In diabetic skeletal muscle, impaired angiogenesis and reduced VEGF-A expression have been observed, whereas in healthy muscle exercise is known to have opposite effects. We studied the effects of type 1 diabetes and combined exercise training on angiogenic mRNA expression and capillarization in mouse skeletal muscle. Microarray and real-time PCR analyses showed that diabetes altered the expression of several genes involved in angiogenesis. For example, levels of proangiogenic VEGF-A, VEGF-B, neuropilin-1, VEGFR-1, and VEGFR-2 were reduced and the levels of antiangiogenic thrombospon…
Nerve conduction velocity and circulating immunocomplexes in type 1 diabetic children.
1991
There is evidence from several laboratories of an increased prevalence of circulating immuno-complexes (CIC) in diabetic patients. It has also been suggested that CIC are pathogenetically related to chronic diabetic complications. The aim of this study was to assess peripheral nerve function in children with Type 1 diabetes and to evaluate the relationship between the neurophysiological abnormalities and the possible presence of CIC. The investigation was carried out in 25 Type 1 diabetic patients ranging in age from 7-19 years and in 20 normal controls. Neurophysiological assessment was performed to evaluate motor and sensory conduction velocity on median and tibial nerves. IgG-CIC were de…
Oxidant/antioxidant status in obese children compared to pediatric patients with type 1 diabetes mellitus.
2009
Codoner-Franch P, Pons-Morales S, Boix-Garcia L, Valls-Belles V. Oxidant/antioxidant status in obese children compared to pediatric patients with type 1 diabetes mellitus. Background: Type 1 diabetes (T1D) mellitus and obesity are recognized risk factors for cardiovascular disease (CVD). A common mechanism underlying an increased risk for endothelial dysfunction in these two metabolic diseases is oxidative stress. Objective: To evaluate and compare the oxidant/antioxidant defense systems in children affected with T1D or obesity in order to determine the importance of oxidative stress before the emergence of complications. Subjects: Children with T1D (n = 20) or obesity (n = 22), without com…
Psychological distress of children with early-onset type 1 diabetes and their mothers' well-being
2015
Aim Few studies have focused on the psychological adjustment of pre-adolescent children with type 1 diabetes. This study examined psychosocial functioning in nine- and 10-year-old children with early-onset type 1 diabetes, and their mothers, and associations between psychosocial functioning and diabetes management. Methods The mothers of 63 children with early-onset diabetes and 86 healthy children evaluated their own psychosocial functioning, and their child's, with standardised rating scales. We used general linear models to analyse the children's behaviour problems and the mothers' well-being. Associations between the children's behaviour problems, diabetes-related measures and the mothe…
Remission phase in children diagnosed with type 1 diabetes in years 2012 to 2013 in Silesia, Poland: An observational study
2018
Background/objective The study aimed to analyze the frequency of partial remission (PR) and its association with chosen clinical and laboratory factors among pediatric patients with newly diagnosed type 1 diabetes (T1D). The long-term effect of PR on chosen parameters was also investigated. Methods In 194 patients (95 girls) aged 8.1 ± 4.3 years, we analyzed data at T1D onset: glycemia, pH, C-peptide, antibodies, weight, and concomitant autoimmune diseases. Anthropometric parameters, daily insulin requirement (DIR), and HbA1c 2 and 4 years after T1D diagnosis were also analyzed. We determined PR based on HbA1c and DIR measurements at least every 3 months. Results PR occurred in 59% of patie…
Incidence of type 1 diabetes among Polish children ages 0-14 years from 1989-2012.
2014
Aims The incidence of pediatric type 1 diabetes mellitus (T1DM) in Poland is intermediate relative to the rest of the world. T1DM prevalence in the region of Silesia approximates national estimates for all of Poland. This epidemiologic study aimed to analyze the changes in incidence rates of T1DM among children ages 0–14 years from 1989 to 2012 in this region. Methods Data collection methods for the registry followed EURODIAB criteria. To estimate overall population size, data from the Central and regional Statistical Office in Katowice were used. T1DM incidence rates/100,000 children ages 0–14 years/annum and their 95 % CI were calculated for all children and in age subgroups (0–4, 5–9, 10…
