Polymorphisms of the renin-angiotensin system influence height in normotensive women in a Spanish population.
2004
The objective of this study was to analyze the influence of the polymorphisms G-6A of the angiotensinogen gene, insertion/deletion (I/D) of the angiotensin-converting enzyme, and C573T of the angiotensin II AT1 receptor gene on a healthy, middle-age population. A total of 370 (194 women) healthy normotensive Caucasian subjects, aged 25-50 yr old, were selected from the general population. A significant association was found between height and the C573T polymorphism in women (P0.001). After adjustment for age, this association remained significant (P0.002). Thus, the lowest height values were from subjects carrying TT genotype (CC, 1.627 +/- 0.008 m; CT, 1.595 +/- 0.006 m; TT, 1.586 +/- 0.01…
No change in apolipoprotein AI metabolism when subcutaneous insulin infusion is replaced by intraperitoneal insulin infusion in type 1 diabetic patie…
2006
In type 1 diabetic patients, the replacement of subcutaneous insulin infusion by intraperitoneal insulin infusion restores the normal physiological gradient between the portal vein and the peripheral circulation, which is likely to modify HDL metabolism. This stable isotope kinetic study was designed to compare HDL apolipoprotein (apo) AI metabolism in seven type 1 diabetic patients first treated by continuous subcutaneous insulin infusion by an external pump and then 3 months after the beginning of intraperitoneal insulin infusion by an implantable pump. Glycaemic control was comparable under subcutaneous and intraperitoneal insulin infusion (HbA1c=7.34+/-0.94% versus 7.24+/-1.00%, NS). HD…
Binding of monocytes from normolipidemic hyperglycemic patients with type 1 diabetes to endothelial cells is increased in vitro.
2009
Increased endothelial binding and emigration of monocytes play a dominant role in the pathogenesis of atherosclerosis in diabetes mellitus. Previous studies revealed that hyperlipidemia correlates with monocyte binding in vitro. The aim of this study was to characterize the monocyte-endothelial interaction of leucocytes of hyperglycemic patients with type 1 diabetes but lacking hyperlipidemia. We isolated monocytes from healthy controls and normolipidemic type 1 diabetes patients with elevated levels of HbA1c and quantified monocyte binding by an immunoilluminometric cell adhesion assay. Purity of isolated monocytes was at least 98%. Endothelial binding of monocytes from patients with type …
Efect of periodontal disease and non surgical periodontal treatment on C-reactive protein. Evaluation of type 1 diabetic patients
2011
Objectives: The purpose of this study was to analyze how anti-infectious periodontal treatment affects C reactive protein (CRP) values in patients with type 1 diabetes, and correlate baseline CRP levels with periodontal disease severity. Study Design: A cohort of fifty three subjects with type 1 diabetes and moderate to severe periodontitis were recruited. Periodontal parameters were measured, and blood samples were obtained to evaluate high-sensitivity C-reactive protein (hs-CRP). Group 1 was treated with scaling, root planning, and systemic administration of doxycycline. Group 2 received only scaling and root planning. Results: Hs-CRP was reduced after periodontal treatment in group 1 (-0…
Type I Diabetes is the Main Cost Driver in Autoimmune Polyendocrinopathy
2019
Abstract Context Autoimmune polyendocrinopathy (AP), a chronic complex orphan disease, encompasses at least two autoimmune-induced endocrine diseases. Objective To estimate for the first time total, indirect and direct costs for patients with AP, as well as cost drivers. Design Cross-sectional cost of illness study. Setting Academic tertiary referral center for AP. Patients 146 consecutive, unselected AP patients. Intervention Interviews pertaining to patients’ socioeconomic situation covered a recall period of 12 months. Both the human capital (HCA) and the friction cost approaches (FCAs) were applied as estimation methods. Main outcome measures Direct and indirect annual costs, and sick l…
DNA damage in leukocytes and serum nitrite concentration are negatively associated in type 1 diabetes.
2020
Abstract Chronic hyperglycaemia leads to DNA damage in diabetes and might be associated with nitrosative stress. In this study, we aimed at assessing the level of DNA strand breaks in leukocytes, serum nitrite and nitrate in patients with type 1 diabetes and healthy controls and associations of these parameters with diabetes-related outcomes in a prospective study. The level of DNA damage was determined in 71 patients with type 1 diabetes and 57 healthy controls by comet assay and scored with arbitrary units (AU). The chemiluminescence method was used to measure nitrite and nitrate. Clinical information and data on consumption of alcohol, physical activity and smoking were collected. Progre…
Serum levels of substance P are decreased in patients with type 1 diabetes.
2000
Morphological and immunohistochemical studies in diabetic subjects have shown a depletion of the neuropeptide substance P (SP) in the central and peripheral nervous system. This is the first study investigating serum levels of substance P in type 1 diabetes patients (n=50) and controls (n=75) by means of an enzyme immunoassay. The serum level of SP was significantly decreased in the diabetic group compared to the control group (10.12+/-0.29 vs. 12.25+/-0.38 pg/ml; p<0.0001). In diabetic patients, there was no correlation of substance P levels with age, serum creatinine, albuminuria, total cholesterol, HDL- or LDL-cholesterol, triglycerides, HbA1c, type or duration of diabetes and gender. Fu…
Cardiovascular autonomic neuropathy in type 1 diabetic patients with and without peripheral neuropathy.
1998
One hundred Type 1 diabetic patients (54 men, 46 women) mean age 28.9 +/- 8.4 years, were selected from among individuals referred to our hospital, with no previous diagnosis of diabetic chronic complications including diabetic neuropathy. After clinical and physical examinations, subjects were divided into two groups: with (n = 37) and without (n = 63) peripheral neuropathy. The percentage of subjects with cardiovascular autonomic neuropathy (AN), diagnosed by positive results to at least two of the five cardiovascular tests (Valsalva ratio, EI ratio, 30/15 ratio, blood-pressure response to standing up and handgrip test), was 40%: 72.9% in the group with peripheral neuropathy and 20.6% in …
Simultaneous Pancreas Kidney Transplantation Improves Cardiovascular Autonomic Neuropathy with Improved Valsalva Ratio as the Most Precocious Test
2020
Background. Simultaneous pancreas-kidney (SPK) transplantation is a proven option of treatment for patients with type 1 diabetes mellitus (T1DM) and related end-stage renal disease. There is discrepancy between the results of different studies about the impact of prolonged normalization of glucose metabolism achieved by SPK on the course of diabetic complications including severe forms of diabetic neuropathy. The objective of the study was to evaluate the prevalence of cardiovascular autonomic neuropathy (CAN) in patients undergoing SPK transplantation and its evolution 10 years after transplantation. Methods. Prospective study of 81 patients transplanted in a single center from year 2002 t…
Predictive model to identify the risk of losing protective sensibility of the foot in patients with diabetes mellitus
2019
Diabetic neuropathy is defined as the presence of symptoms and signs of peripheral nerve dysfunction in diabetics. The aim of this study is to develop a predictive logistic model to identify the risk of losing protective sensitivity in the foot. This descriptive cross‐sectional study included 111 patients diagnosed with diabetes mellitus. Participants completed a questionnaire designed to evaluate neuropathic symptoms, and multivariate analysis was subsequently performed to identify an optimal predictive model. The explanatory capacity was evaluated by calculating the R (2) coefficient of Nagelkerke. Predictive capacity was evaluated by calculating sensitivity, specificity, and estimation o…
