The aims were to assess the prevalence and characteristics of dyslipidemia phenotypes in a Romanian population-based sample from the PREDATORR study., Methods: PREDATORR was an epidemiological study with a cross-sectional, cluster random sampling design. Participants were classified into four dyslipidemia phenotypes based on the NCEP ATP III criteria: isolated hypertrigliceridemia, isolated hypoHDL-C, isolated hyperLDL-C and mixed dyslipidemia (≥2 standard lipid abnormalities). Overall, 2656 were included in the analysis by dyslipidemia phenotypes., Results: An estimated 67.1% of Romanian adults have at least one lipid abnormality: 27.5% (95%CI26.0-28.9%) have elevated TG, 29.4% (95%CI27.9-30.8%) have low HDL-C and 47.8% (95%CI46.3-49.2%) have elevated LDL-C (26.2% had LDL-C levels ≥2.58 mmol/l associated with CHD or CHD risk equivalent). Also, 30% Romanian adults have mixed dyslipidemia with 7.6% (95%CI6.1-9.0%) having all three lipid abnormalities. THE AGE: and sex-adjusted prevalence of isolated dyslipidemia phenotypes in Romanian adult population was 23.7% (95%CI22.2-25.1%) for hyperLDL-Cholesterolemia, 9.3% (95%CI7.8-10.7%) for hypoHDL-Cholesterolemia and 4.1% (95%CI2.6-5.5%) for hypertriglyceridemia. Among participants with triglycerides ≥2.25 mmol/l, 15.2% (95%CI13.7-16.6%) of Romanian adults have non-HDL-C levels ≥3.36 mmol/l., Conclusions: The PREDATORR survey indicated a high prevalence of dyslipidemia phenotypes in the Romanian population aged 20-79 years, providing data on its association with several cardiometabolic risk factors., (Copyright © 2018 Diabetes India.

Endothelial dysfunction and the related increase in reactive oxygen species (ROS) production are important events in the pathophysiology of diabetes mellitus (DM). Methylene blue (MB) has been systematically investigated for its protective effects against refractory hypotension and mitochondrial dysfunction. We have previously demonstrated that MB improved mitochondrial respiration and partially decreased oxidative stress in diabetic rat hearts. The present study was aimed to investigate whether MB modulates vascular function and ROS production in thoracic aortic rings isolated from rats with streptozotocin-induced DM (after 4 weeks of hyperglycemia). The effects of MB (0.1 μM, 30 min ex vivo incubation) on vascular reactivity in organ chamber (phenylephrine-induced contraction, acetylcholine-induced relaxation) and H 2 O 2 production (assessed by ferrous iron xylenol orange oxidation assay) were investigated in vascular preparations with intact endothelium and after denudation. DM elicited a significant alteration of vascular function: increased contractility to phenylephrine, attenuation of acetylcholine-dependent relaxation, and augmented H 2 O 2 generation. Ex vivo incubation with MB partially reversed all these changes (by approximately 70%) in vascular segments with intact endothelial layer (but not in denuded vessels). In conclusion, MB might be useful in alleviating endothelial dysfunction and mitigating endothelial oxidative stress, observations that clearly require further investigation in the setting of cardiometabolic disease.

Studies published so far using ultrasound-based elastography in the kidneys, lack to prove a clear relationship between kidney shear wave speed (KSWS) and renal disease progression. Taking into account that the kidney is a highly vascularized organ, the present study aims to find a relationship between KSWS and vascular factors (blood pressure [BP], arterial stiffness). Our study included 38 diabetic kidney disease patients (mean age 56.52 ± 16.12 years, 19 female, 19 male). KSWS, an indicator of renal stiffness, was measured using point Shear Wave Elastography (pSWE; Siemens Acuson S2000). In every patient, we recorded BP, and we measured aortic augmentation index (AAI) and brachial pulse wave velocity (PWV), using oscillometry. We found statistically significant indirect correlations of KSWS with indicators of arterial stiffness, such as PWV ( r = -.41, p = .036), and AAI ( r = -.37, p = .031). We found also an indirect correlation of KSWS with diastolic BP ( r = -.65, p = .02) and systolic BP ( r = -.54, p = .008). We found no correlation of KSWS with estimated glomerular filtration rate (eGFR), urinary albumin/creatinine ratio, stage of diabetic retinopathy, or glycated hemoglobin. Our study shows that high BP and the progression of arteriosclerosis (high PWV and AAI), leads to a decrease of renal stiffness. Thus, it seems that KSWS is influenced by renal blood flow, rather than other factors, such as albuminuria or chronic kidney disease stage.

Background: The impact of smoking on morbidity is well known, but in Romania, limited data are available regarding the smoking prevalence and relationship with cardiometabolic profile and kidney function., Objectives: To assess the association of smoking with cardiometabolic traits and kidney function, in a Romanian population-based sample from the PREDATORR study., Methods: PREDATORR was an epidemiological cross-sectional study. Between 2012 and 2014, participants were randomly selected from the lists of general practitioners and enrolled if they were aged 20 to 79 years, born and living in the past 10 years in Romania. Sociodemographic and lifestyle characteristics were collected through interviewer-administered questionnaires., Results: Overall, 2704 participants were included in the analysis, 18% of them being current smokers and 30.8% former smokers. Current smokers compared to non-smokers had higher total cholesterol (220.6 ± 50.4 versus 213.9 ± 86.8 mg/dl, P = 0.017), LDL-cholesterol (137.8 ± 45.2 versus 130.7 ± 83.7 mg/dl, P = 0.004) and glomerular filtration rate (96.9 ± 16.8 versus 90.7 ± 19.1 ml/min/1.73 m 2 , P <0.001) in women and higher triglycerides (170.7 ± 129.8 versus 144.3 ± 94.2 mg/dl, P = 0.007), glomerular filtration rate (97.6 ± 17 versus 90.3 ± 18 ml/min/1.73 m 2 , P < 0.001) and lower HDL-cholesterol (48 ± 15.5 versus 50.4 ± 14.1 mg/dl, P = 0.002) in men. Active smoking was associated with hypercholesterolaemia [OR: 1.40 (95% CI: 1.01-1.96), P = 0.04] and low HDL-cholesterolaemia [OR: 1.39 (95% CI: 1.01-1.91), P = 0.04] and negatively associated with overweight/obesity [OR: 0.67 (95% CI: 0.48-0.94), P = 0.02]. Male former smokers had higher prevalence of abdominal obesity (82.4% versus 76.4%, P = 0.02), hypertriglyceridaemia (43.6% versus 35.6%, P = 0.01), hypertension (64% versus 56.4%, P = 0.01) and ischaemic vascular disease (40.5% versus 30.9%, P = 0.003) than male non-smokers., Conclusion: The PREDATORR study showed a high prevalence of smoking in the adult Romanian population providing data on the association of smoking with cardiometabolic traits.

Introduction: Acute kidney injury (AKI) increases the risk of death in acute ischemic stroke (AIS) patients. Intravenous thrombolytic therapy (iv. rt-PA) seems to be the most effective treatment for AIS patients. The effects of AKI on iv. rt-PA treated AIS cases is less studied. Our paper addresses this issue., Methods: 45 consecutive stroke patients treated with iv. rt-PA (median age = 64 years; 29 male) and 59 age and sex matched controls not eligible for iv. rt-PA have been enrolled in our study. Subjects were followed-up until hospital release or death (median follow up time = 12 days)., Results: The prevalence of AKI did not differ between iv. rt-PA treated patients and controls (35.5% vs. 33.89%). In both groups, AKI was associated with increased in-hospital mortality: 50.0% vs. 3.4% p<0.0001 (in the rt-PA treated), and 45% vs. 30.7% (in controls). AKI iv. rt-PA treated patients had a significantly higher risk of in hospital mortality as compared to the no-AKI iv. rt-PA treated (HR = 15.2 (95%CI [1.87 to 124.24]; P = 0.011). In a Cox-multivariate model, the presence of AKI after iv. rt-PA remained a significant factor (HR = 8.354; p = 0.041) influencing the in-hospital mortality even after correction for other confounding factors. The independent predictors for AKI were: decreased eGFR baseline and elevated serum levels of uric acid at admission, (the model explained 60.2% of the AKI development)., Conclusions: The risk of AKI was increased in AIS patients. Thrombolysis itself did not increase the risk of AKI. In the iv. rt-PA patients, as compared to non-AKI, those which developed AKI had a higher rate of in-hospital mortality. The baseline eGFR and the serum uric acid at admission were independent predictors for AKI development in the iv. rt-PA treated AIS patients.

In previous studies of acoustic radiation force impulse (ARFI) elastography, using Virtual Touch tissue quantification (VTQ) (Siemens Acuson S2000), it was reported that the measurement of renal shear wave speed in patients with chronic kidney disease (CKD) is not influenced exclusively by renal fibrosis. The purpose of the present study was to analyze the role of VTQ in patients with diabetic kidney disease, considered the main cause of CKD. The study group included 164 patients: 80 patients with diabetic kidney disease (DKD) and 84 without renal disease or diabetes mellitus. In each subject in lateral decubitus, five valid VTQ measurements were performed in each kidney and a median value was calculated, the result being expressed in meters/second. The following means of the median values were obtained In DKD patients, the means of the median values were for VTQ right kidney, 2.21 ± 0.71 m/s, and for VTQ left kidney, 2.13 ± 0.72 m/s, whereas in the normal controls statistically significant higher values were obtained: 2.58 ± 0.78 m/s for VTQ right kidney (p = 0.0017) and 2.46 ± 0.81 m/s for VTQ left kidney (p = 0.006). Patients with an estimated glomerular filtration rate (eGFR) >60 mL/min (DKD stages 1 and 2 together with normal controls) had a significantly higher kidney shear wave speed compared with patients with an eGFR <60 mL/min (2.53 m/s vs. 2.09 m/s, p < 0.05). In the DKD group, there was a significant correlation between eGFR and VTQ levels for the right kidney (r = 0.28, p = 0.04). There was no correlation of VTQ values with proteinuria level, stage of diabetic retinopathy or glycated hemoglobin. Our study indicates that shear wave speed values in patients with diabetic kidney disease and eGFRs <60 mL/min are significantly lower compared with those of patients with eGFRs >60 mL/min (either normal controls or diabetic patients with DKD stages 1 and 2), and values decrease with the decrease in eGFR. However, proteinuria, diabetic retinopathy and glycated hemoglobin have no influence on VTQ., (Copyright © 2017 World Federation for Ultrasound in Medicine & Biology. Published by Elsevier Inc.

In patients with type 1 diabetes mellitus (T1DM), glucose dynamics are influenced by insulin reactions, diet, lifestyle, etc., and characterized by instability and nonlinearity. With the objective of a dependable decision support system for T1DM self-management, we aim to model glucose dynamics using their nonlinear chaotic properties. A group of patients was monitored via continuous glucose monitoring (CGM) sensors for several days under free-living conditions. We assessed the glycemic variability (GV) and chaotic properties of each time series. Time series were subsequently transformed into the phase-space and individual autoregressive (AR) models were applied to predict glucose values over 30-minute and 60-minute prediction horizons (PH). The logistic smooth transition AR (LSTAR) model provided the best prediction accuracy for patients with high GV. For a PH of 30 minutes, the average values of root mean squared error (RMSE) and mean absolute error (MAE) for the LSTAR model in the case of patients in the hypoglycemia range were 5.83 ( ± 1.95) mg/dL and 5.18 ( ± 1.64) mg/dL, respectively. For a PH of 60 minutes, the average values of RMSE and MAE were 7.43 ( ± 1.87) mg/dL and 6.54 ( ± 1.6) mg/dL, respectively. Without the burden of measuring exogenous information, nonlinear regime-switching AR models provided fast and accurate results for glucose prediction.

Objectives: Due to the shortage of living kidney donors and the current diabetes mellitus (DM) pandemic, studying the association of solitary kidney (SK) with DM is of paramount importance. Our aim was to assess the significance of the association between SK and DM., Materials and Methods: Eighty-four patients with SK and DM (group A), with a mean age of 62.46±12.72 years, of whom 36 were males and 48 were females, were enrolled in the study. The control group (group B) comprised 84 SK patients without DM of similar age and duration of existence of a SK. Mean age: 61.58±8.22 years, 23 males and 61 females. Serum creatinine, GFR (CKD-EPI), glycaemia, cholesterol, triglycerides, uric acid, proteinuria/24h, systolic blood pressure (SBP), diastolic blood pressure (DBP) and BMI were assessed., Results: The group of patients with SK and DM (group A) had a higher BMI (p=0.0007), higher metabolic abnormalities (higher glycaemia [p<0.001], triglycerides [p=0.0004], uric acid [p=0.019] and proteinuria/24h [p=0.006]). The study group also had a higher prevalence of hypertension (p=0.003) and coronary artery disease (p=0.031)., Conclusions: We found a higher value of proteinuria in the study group, significant metabolic abnormalities, as well as a higher prevalence of hypertension and coronary artery disease. However, no differences with respect to GFR were found, which could have significant implications for transplantation., (Copyright © 2016 Sociedad Española de Nefrología.

Background and Aims: 2D-shear wave elastography (2D-SWE) is a relatively new elastographic technique. The aim of the present study is to determine the values of the elasticity indexes (EI) measured by 2D-SWE in parathyroid benign lesions (adenomas or hyperplasia) and to establish if this investigation is helpful for the preoperative identification of the parathyroid adenoma., Material and Methods: The study groups were represented by 22 patients with primary or tertiary hyperparathyroidism, diagnosed by specific tests, and 43 healthy controls, in whom the thyroid parenchyma was evaluated, in order to compare the EI of the thyroid tissue with those of the parathyroid lesions., Results: The mean EI measured by 2D-SWE in the parathyroid lesions was 10.2 ± 4.9 kPa, significantly lower than that of the normal thyroid parenchyma (19.5 ± 7.6 kPa; p = 0.007), indicating soft tissue. For a cutoff value of 12.5 kPa, the EI assessed by 2D-SWE had a sensitivity of 93% and a specificity of 86% (AUC = 0.949; p < 0.001) for predicting parathyroid lesions., Conclusion: A value lower than 12.5 kPa for the mean EI measured by 2D-SWE can be used to confirm that the lesion/nodule is a parathyroid adenoma.

Patients with end-stage renal disease (ESRD) have an increased risk of all-cause mortality. The prognostic value of the new cardiac biomarkers, cardiotrophin 1 (CT-1) and galectin 3 (GAL-3), has not yet been defined in hemodialysis (HD) patients. The aim of this study was to determine the use of these novel biomarkers for predicting mortality in HD patients. Plasma GAL-3 and CT-1 concentrations were determined (at baseline) in 88 HD patients followed for 22.2 ± 4.7 months. During the follow-up period, 21 (23.9%) deaths were recorded. According to Cox analysis, the cutoff point for GAL-3 as a predictor of mortality was 23.73 ng/mL, while the cutoff point for CT-1 as a predictor of mortality was 36 pg/mL. In univariate analysis, only GAL-3 >23.73 ng/mL was an independent predictor of mortality (hazard ratio 2.60; 95% confidence interval, 1.09-6.18). In a multivariable Cox proportional hazards model, GAL-3 levels above the cutoff value remained an independent predictor of all-cause mortality. Our data suggest that similar to the general population, GAL-3 is an independent predictor of mortality in HD patients., (© The Author(s) 2016.)

Medullary thyroid carcinoma (MTC) is a rare form of malignancy, having an intermediate prognosis. Controversies exist regarding the best surgical approach. The aim of the study was to analyze the outcome in a group of patients with MTC, diagnosed and followed up in a single care center. We performed a retrospective analysis of all the patients diagnosed with MTC in the Department of Endocrinology from the County Emergency Hospital Timisoara between 1992 and 2012. The study group included 19 patients, 6 men (31.6 %), mean age 41.2 ± 12.5 years (20-72 years). The preoperative diagnosis was based on the protocol for nodular thyroid disease. Total or near-total thyroidectomy was performed in 10 out of 16 patients who could be operated. Postoperative follow-up included repeated measurements of serum calcitonin and imaging investigations. Nine out of the total of 19 (47.3 %) patients had hereditary forms of MTC. Most of the cases (84.2 %) were submitted to surgery. The median duration of follow-up was 84 months. The pTNM staging indicated that the majority of the patients with hereditary MTC were diagnosed in an earlier stage. Disease remission was achieved in 7 cases (43.8 %). Four patients, all with sporadic forms, died. Survival rates at 1, 5 and 10 years were significantly higher (p = 0.048) in patients with hereditary MTC. An early diagnosis of MTC allows a better surgical approach and an improved survival rate. We support the general recommendation that modified radical neck dissection is not necessary for all the patients with MTC.

Background and Aims: Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide. The aim of our study was to evaluate a population of diabetic patients regarding the severity of liver steatosis and liver fibrosis., Methods: The study included 392 type 2 diabetic patients prospectively randomized, evaluated in the same session by transabdominal ultrasound to assess steatosis and by liver elastography to assess fibrosis (Transient Elastography - TE, FibroScan, EchoSens). Steatosis severity was graded using a semi-quantitative scale (S0-no steatosis; S1-mild steatosis; S2-moderate steatosis; S3-severe steatosis). For differentiation between stages of liver fibrosis, the following cut-off values were used (Wong et al., 2010): F2-F3: 7-10.2kPa, F4>/=10.3 kPa., Results: Reliable elastographic measurements were obtained in 76% (298/392) patients. By using the proposed cut-off values, significant fibrosis (F2-F3) was found in 18.8% (56) patients with steatosis, while 13.8% (41) had cirrhosis (F4). Significant fibrosis (F2-F3) was found in 20.4% (20/98) of the patients with S1, in 18.6% (22/118) of those with S2 and in 31.8% (14/44) of those with S3, while cirrhosis (F4) was diagnosed in 7.1% (7/98) patients with S1, in 20.3% (24/118) of those with S2 and in 22.7% (10/44) of those with S3., Conclusions: Liver steatosis diagnosed by ultrasound is very frequently found in type 2 diabetes mellitus patients, more than half of them having moderate/severe steatosis. A significant liver stiffness increase was found in more than 30% of these patients. Liver stiffness assessment in type 2 diabetic patients should be performed systematically to identify those with significant liver fibrosis.

Objective: The Roma minority represents the largest ethnic group in Central and South-East European countries. Data regarding the mortality in Roma hemodialysis subjects are limited. We evaluated the 3 year mortality of ESRD Roma patients treated with hemodialysis (HD)., Study Design and Setting: Our prospective cohort study included 600 ESRD patients on HD therapy recruited from 7 HD centers, from the main geographical regions of Romania. The median age of the patients was 56 (19) years, 332 (55.3%) being males, 51 (8.5%) having Roma ethnicity., Results: Roma ESRD patients initiate dialysis at a younger age, 47.8 years vs. 52.3 years (P = 0.017), present higher serum albumin (P = 0.013) and higher serum phosphate levels (P = 0.021). In the Roma group, the overall 3 year mortality was higher when compared to Caucasians (33.3% vs. 24.8%). The multivariate survival analysis revealed that being of Roma ethnicity is an independent risk factor for mortality (HR = 1.74; 95% CI = 1.04-2.91; P = 0.035)., Conclusions: Roma patients with ESRD initiate HD therapy at a younger age as compared to Caucasians. They have a higher 3 year mortality rate and are dying at a younger age. Roma ethnicity represents an independent risk factor for mortality in our cohort.

Background: The PREDATORR (PREvalence of DiAbeTes mellitus, prediabetes, overweight, Obesity, dyslipidemia, hyperuricemia and chronic kidney disease in Romania) study is the first national study analyzing the prevalence of diabetes mellitus (DM) and prediabetes, and their association with cardiometabolic, sociodemographic, and lifestyle risk factors in the Romanian population aged 20-79 years., Methods: This was an epidemiological study with a stratified, cross-sectional, cluster random sampling design. Sociodemographic, lifestyle, and anamnestic data were collected through self- and interviewer-administered questionnaires, and biochemical assays and oral glucose tolerance tests were performed., Results: In all, 2728 participants from 101 clinics of general practitioners were randomly selected, with a probability proportional to population size according to the 2002 Romanian Census. The participation rate was 99.6%. Impaired glucose regulation (prediabetes, known and unknown DM) was found in 28.1% of the study population. The overall age- and sex-adjusted prevalence of DM was 11.6% (95% CI 9.6%-13.6%), of which 2.4% (95% CI 1.7%-3.1%) had unknown DM. The prevalence of DM increased with age and was higher in men than in women. The age- and sex-adjusted prevalence of prediabetes was 16.5% (95%CI 14.8%-18.2%), with the highest percentage in the 60-79 year age group and in women. Obesity, abdominal obesity, dyslipidemia, low education level, and a family history of diabetes were associated with glucose metabolism disorders., Conclusions: The PREDATORR study shows a high prevalence of impaired glucose regulation in the adult Romanian population, providing data on the prevalence of DM and prediabetes and their association with several risk factors., (© 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley Sons & Australia, Ltd.)

Introduction: Diabetic neuropathy (DN) is a prevalent complication of Type 2 Diabetes Mellitus (T2DM) with a major impact on the health of the affected patient. We hypothesized that mediated by the dysfunctionalities associated with DN's three major components: sensitive (lack of motion associated sensory), motor (impairments in movement coordination) and autonomic (the presence of postural hypotension), the presence of DN may impair the balance in the affected patients. Our study's main aim is to evaluate the possible association between the presence and severity of DN and both the balance impairment and the risk of falls in patients with T2DM., Material and Method: In this cross-sectional study we enrolled, according to a consecutive-case population-based setting 198 patients with T2DM. The presence and severity of DN was evaluated using the Michigan Neuropathy Screening Instrument, a tool which allows both diagnosing and severity staging of DN. The balance impairment and the risk of falls were evaluated using four validated and standardized tools: Berg Balance Scale (BBS), Timed-up and Go test (TUG), Single Leg Stand test (SLS) and Fall Efficacy Scale (FES-I)., Results: The presence of DN was associated with significant decreases in the BBS score (40.5 vs. 43.7 points; p<0.001) and SLS time (9.3 vs. 10.3 seconds; p = 0.003) respectively increases in TUG time (8.9 vs. 7.6 seconds; p = 0.002) and FES-I score (38 vs. 33 points; p = 0.034). The MNSI score was reverse and significantly correlated with both BBS score (Spearman's r = -0.479; p<0.001) and SLS time (Spearman's r = -0.169; p = 0.017). In the multivariate regression model, we observed that patient's age, DN severity and depression's symptoms acted as independent, significant predictors for the risk of falls in patients with T2DM., Conclusions: The presence of DN in patients with DM is associated with impaired balance and with a consecutively increase in the risk of falls.

Background: Distal symmetric polyneuropathy (DSPN) is the most common complication of type 2 diabetes mellitus (T2DM) and the most common form of peripheral neuropathy. DSPN increases the risk of foot ulceration up to seven-fold, and is a significant risk factor in more than 60 % of the amputations of the lower limbs in patients with T2DM. The aims of our study were to evaluate the difference in the density of intraepidermal nerve fibers (IENF) in patients with respectively without DSPN, to evaluate the strength of the relationship between the symptomatology of the DSPN and IENF density and to define a cutoff value of the IENF density for the diagnosis of DSPN., Methods: We enrolled, according to a consecutive, population-based method, 36 patients with T2DM admitted in our Clinic. For all patients, we measured HbA1c, lipid profile, body mass index and we assessed the presence and severity of DSPN using the evaluation of clinical symptoms, nerve conduction velocity and IENF density quantification., Results: The presence of neuropathy was significantly associated with a decreased density of IENF for both the proximal (11.6 vs. 14.9 fibers/mm; p = 0.014) and the distal biopsies (7.2 vs. 8.6 fibers/mm; p = 0.020). The optimal threshold value of IENF density (the point with the maximum sum of specificity and sensitivity), according to our model, was 10.1 fibers/mm., Conclusions: Skin biopsy followed by IENF density quantification is a valid, reliable tool for the diagnosis of DSPN.

Chronic glomerulonephritis is related to focus infection. Odontogenic foci are frequently involved in glomerulonephritis. The relationship with the odontogenic focus infection can be demonstrated by the occurrence or aggravation of the symptoms of glomerulonephritis: proteinuria, haematuria, high blood pressure and oedema. Glomerular impairment in glomerulonephritis occurs together with inflammatory alterations of the tubulointerstitial compartment that can play an important part in the evolution of the disease. Tubular urinary markers can indicate the activation of this compartment during an infection of a focus, an odontogenic focus in our study.The paper aims at demonstrating the relationship between the odontogenic focus infection and tubulointerstitial lesions, assessed by a tubular urinary marker, N-acetyl beta-D glucosaminidase (NAG).We investigated the urinary N-acetyl beta-D glucosaminidase of 20 patients with chronic glomerulonephritis who presented odontogenic focus infections, comparing them with patients with chronic glomerulonephritis without odontogenic foci and of 20 controls, clinically healthy persons.Chronic glomerulonephritis patients with odontogenic focus infection presented clearly increased values as compared to clinically healthy control persons of urinary N-acetyl beta-D glucosaminidase.These patients underwent surgical intervention on the odontogenic focus under antibacterial prophylactic treatment. In 75% cases, the values of N-acetyl beta-D glucosaminidase diminished, indicating the favourable effect of the treatment of the odontogenic focus on the tubulointerstitial compartment in patients with chronic glomerulonephritis. In 25% cases this therapeutic treatment was associated with an increase of the values of urinary N-acetyl beta-D glucosaminidase, expressing its unfavourable effect on chronic glomerulonephritis.Urinary N-acetyl beta-D glucosaminidase indicated an etiopathogenetic relationship between the odontogenic focus and the tubulointerstitial compartment in chronic glomerulonephritis.

Diabetic nephropathy (DN) is a frequent and severe complication of diabetes mellitus (DM). Its diagnosis in incipient stages may allow prompt interventions and an improved prognosis. Towards this aim, biomarkers for detecting early DN can be used. Microalbuminuria has been proven a remarkably useful biomarker, being used for diagnosis of DN, for assessing its associated condition-mainly cardiovascular ones-and for monitoring its progression. New researches are pointing that some of these biomarkers (i.e., glomerular, tubular, inflammation markers, and biomarkers of oxidative stress) precede albuminuria in some patients. However, their usefulness is widely debated in the literature and has not yet led to the validation of a new "gold standard" biomarker for the early diagnosis of DN. Currently, microalbuminuria is an important biomarker for both glomerular and tubular injury. Other glomerular biomarkers (transferrin and ceruloplasmin) are under evaluation. Tubular biomarkers in DN seem to be of a paramount importance in the early diagnosis of DN since tubular lesions occur early. Additionally, biomarkers of inflammation, oxidative stress, podocyte biomarkers, and vascular biomarkers have been employed for assessing early DN. The purpose of this review is to provide an overview of the current biomarkers used for the diagnosis of early DN.

Purpose: PREDATORR is the first national study analyzing the prevalence of chronic kidney disease and its prognosis and association with socio-demographic, cardio-metabolic and lifestyle risk factors in the adult Romanian population., Methods: Chronic kidney disease was defined according to the KDIGO 2012 criteria as an estimated glomerular filtration rate <60 mL/min/1.73 m(2) and/or urinary albumin-to-creatinine ratio ≥30 mg/g. The socio-demographic, lifestyle and anamnestic data were collected through interviewer-administered questionnaires. Physical examination and biochemical assays were also performed., Results: This cross-sectional study conducted between December 2012 and February 2014 in Romania included 2717 adults. The overall age- and sex-adjusted prevalence of chronic kidney disease was 6.74 % (95 %CI 5.60-7.88 %), of which 3.31 % (2.50-4.13 %) had only reduced kidney function (estimated glomerular filtration rate <60 mL/min/1.73 m(2)), 2.98 % (2.21-3.76 %) had only albuminuria, and 0.45 % (0.14-0.74 %) had both. The prevalence of chronic kidney disease increased with age and was similar in women and in men. Age, hyperuricemia, impaired glucose regulation (diabetes/prediabetes), hypertriglyceridemia and a family history of renal disease were independent risk factors for the presence of chronic kidney disease., Conclusions: The PREDATORR study showed a high prevalence of chronic kidney disease in the adult Romanian population providing data on its prognosis and association with several cardio-metabolic risk factors.

Background: End stage renal disease (ESRD) patients on renal replacement therapy (RRT) with diabetes mellitus (DM) have a higher mortality rate and an increase prevalence of vitamin D deficiency compared to those without DM. It is still debated if vitamin D deficiency is a risk factor or a prognostic marker for mortality in these patients. This study investigated the prevalence of vitamin D deficiency and its impact on all-cause mortality in HD patients with DM., Methods: Our prospective non-interventional cohort study included 600 patients on hemodialysis therapy (HD) (median aged 56, interquartile range (19) years, 332 (55.3%) males) recruited from 7 HD centers, from all main geographical regions of Romania. The prevalence of DM was 15.3%. They were then followed regarding: dialysis duration, dialysis efficiency, renal anemia, CKD-MBD, inflammatory status and comorbidities: coronary artery disease (CAD), peripheral vascular disease (PVD) and stroke. The deficiency of 25-OH vitamin D was defined as a value lower than 12 ng/mL., Results: Patients were followed for 3 years. The overall 3 year mortality was 25.5% (153 individuals), being higher in patients with DM as compared to those without DM (33.7% vs. 24.0%; P = 0.049). The time-related prognosis was also influenced by the presence of DM, at the survival analysis resulting in a HR of 1.52 [1.03 to 2.26] 95% CI, P = 0.037, for death in dialyzed patients with DM. In DM patients, 25-OH vitamin D deficiency was significantly higher (37.0% compared to 24.0%, P = 0.009). Furthermore, in patients with DM we observed a shorter dialysis duration (2 vs. 3 years, P<0.001) and a lower intact parathyroid hormone (iPTH) (258.0 pg/ml vs. 441.9 pg/ml, P = 0.002). Regarding the presence of comorbidities at the inclusion in the study, the presence of diabetes in dialyzed patients was associated with increased prevalence of CAD (87.0% vs. 58.1%, P<0.001), PVD (67.4% vs. 17.3%, P<0.001) and history of stroke (29.3% vs. 14.0%, P<0.001). In patients with DM the presence of 25-OH vitamin D deficiency increased the probability of death (50.0% vs. 24.1%; P = 0.011). In multiple Cox proportional hazards analysis, vitamin D deficiency remained an independent predictor for mortality in dialysis patients with DM (HR = 1.71, 95% CI 1.21 to 2.43, P = 0.003). In the same time, multiple Cox proportional hazards analysis showed that age (HR = 1.02 per one year increase, P = 0.004), CAD (HR = 1.55, P = 0.046) and PVD (HR = 1.50, P = 0.029) were independent predictors for mortality in dialysis patients with DM., Conclusions: ESRD patients with DM treated with HD have a higher overall mortality than non-DM patients. Vitamin D deficiency is significantly more prevalent in HD patients with DM. Low 25-OH vitamin D levels were associated with increased all-cause mortality in these patients. According to our data, in HD patients with DM, screening for vitamin D deficiency (and its correction) should be mandatory for an optimal risk reduction strategy.

Objective: To evaluate and compare the values of the elasticity index as measured by shear wave elastography in healthy subjects and in patients with autoimmune thyroid disease, in order to establish if this investigation can predict the occurrence of autoimmune thyroid disease., Methods: A total of 104 cases were included in the study group: 91 women (87.5%), out of which 52 (50%) with autoimmune thyroid disease diagnosed by specific tests and 52 (50%) healthy volunteers, matched for age and gender. For all the subjects, three measurements were performed on each thyroid lobe and a mean value was calculated. The data were expressed in kPa. The investigation was performed with an Aixplorer system (SuperSonic Imagine, France), using a linear high-resolution 15-4 MHz transducer., Results: The mean value for the elasticity index was similar in the right and the left thyroid lobes, both in normal subjects and in patients with autoimmune thyroid disease: 19.6 ± 6.6 vs. 19.5 ± 6.8 kPa, p = 0.92, and 26.6 ± 10.0 vs. 25.8 ± 11.7 kPa, p = 0.71, respectively. This parameter was significantly higher in patients with autoimmune thyroid disease than in controls (p < 0.001). For a cut-off value of 22.3 kPa, which resulted in the highest sum of sensitivity and specificity, the elasticity index assessed by shear wave elastography had a sensitivity of 59.6% and a specificity of 76.9% (AUROC = 0.71; p < 0.001) for predicting the presence of autoimmune thyroid disease., Conclusion: Quantitative elasticity index measured by shear wave elastography was significantly higher in autoimmune thyroid disease than in normal thyroid parenchyma and may predict the presence of autoimmune thyroid disease.

Vitamin D deficiency is still a common problem particularly in the elderly and in individuals with various degrees of renal impairment. The present study aimed to evaluate the association between plasma concentrations of 25(OH)D and death in a large cohort of prevalent patients on hemodialysis (HD) from south-east Romania, a typical Balkan region. This is an observational prospective study that included a total of 570 patients on maintenance HD. Study patients were classified into three groups by baseline 25(OH)D levels: (1) sufficient 25(OH)D--i.e., >30 ng/mL; (2) insufficient 25(OH)D--i.e., between 10 and 29 ng/mL; and (3) deficient 25(OH)D--i.e., <10 ng/mL. During the follow-up period of 14 months, 68 patients (11.9%) died, the Kaplan-Meier analysis showing significant differences in all-cause mortality for chronic kidney disease patients in different 25(OH)D groups (P = 0.002). Unadjusted Cox regression analysis also showed significant differences in survival. The multivariate Cox regression model showed no significant differences in survival according to vitamin D levels. Hazard ratio for death in the "<10 ng/mL" group was 1.619 (P = 0.190) and in the "10-30 ng/mL" group was 0.837 (P = 0.609). In our dialysis population with a high comorbidity burden, low 25(OH)D concentration was not associated with mortality in the adjusted Cox model, suggesting that vitamin D deficiency could represent only a non-specific marker for a poor health status, with less impact on mortality., (© 2014 International Society for Hemodialysis.)

Background: The epidemiology of type 1 diabetes mellitus may provide insights into the pathogenesis of the disease., Objective: The aim of this work was to characterize the trend of the incidence of type 1 diabetes mellitus in Romanian children aged from 0 to 17 years over a 10-year interval., Subjects and Methods: Data regarding new cases were obtained from two sources: (1) The Romanian Childhood Diabetes Registry and (2) Records of the Medical Center "Cristian Serban", Buzias. The demographic data were retrieved from the National Institute for Statistics. The incidence was calculated for the age groups 0-4, 5-9, 10-14, and 15-17 years., Results: A total of 3196 new cases, aged below 18 years, were found by both the sources. There were significant differences between the groups (p=0.012), the mean incidence being highest in the age group 10-14 years (9.6/100,000/year, 95% CI 9-10.1) and lowest in children aged from 0 to 4 years (4.8/100,000/year, 95% CI 4.4-5.3). Boys were slightly more frequently affected than girls (p=0.038). The age and gender adjusted incidence of type 1 diabetes mellitus increased significantly (p<0.001) from 6.2/100,000/year (95% CI 5.5-6.9) in 2002 to 9.3/100,000/year (95% CI 8.4-10.3) in 2011. The raise in incidence was noticed in all age groups except for 15-17 years., Conclusion: Romania is a country with an intermediate incidence of type 1 diabetes mellitus in children, which is slightly higher in boys than in girls. The incidence of type 1 diabetes mellitus increased continuously during the 10-year survey, with the exception of the oldest teens.

Background: After 10 years of systematically nationwide applied measures for reduction of infection risk, in this national prospective observational study, we reassessed the prevalence of hepatitis virus infection prevalence and its influence on the outcome of end-stage kidney disease (ESKD) patients treated with hemodialysis., Methods: Six-hundred ESKD patients (332 men and 268 women, median age 56 years) treated with chronic HD in seven centers from all the historical regions of Romania have been assigned to this study on 1st of November 2010. The aims of this study were to reevaluate the prevalence of the hepatitis B and C virus infection in a HD population from Romania after 10 years of systematically nationwide applied measures for reduction of infection risk and also to assess the impact of these infections on the prognosis of HD patients., Results: HBsAg was positive in 9.5% (n = 57) of the patients, anti-HCV antibodies were detected in 27.3% (n = 164) and 5% (n = 30) were positive for both HBV and HCV infection. The mortality risk was significantly influenced only by age, the presence of coronary artery disease and the 25 OH vitamin D levels., Conclusions: This study shows that the systematically nationwide applied measures for reduction of infection risk significantly decreased HV infection prevalence in HD patients in Romania. The presence of HV infection did not significantly influence the mortality risk in this population.

Background: Type 1 diabetes mellitus in pregnant women is associated with an increased risk of congenital malformations, obstetric complications, neonatal morbidity, and mortality. Our aim was to evaluate which factors from the first trimester of pregnancy have a significant impact on the pregnancy outcomes of women with type 1 diabetes., Methods: We included 94 pregnant women with type 1 diabetes in this study. In these patients, we analyzed the influence of several diabetes-related parameters on the pregnancy outcome. We compared the parameters between two cohorts: those with successful pregnancies and those with adverse pregnancy outcomes, defined as spontaneous abortion or congenital malformations. The influence of several factors on the pregnancy outcome was assessed using multivariate and univariate logistic regressions., Results: The prevalence of adverse pregnancy outcomes was 28.7%, and was associated with poorer glycemic control (p <0.001), lower frequency of daily self-monitoring tests (p <0.001), smoking status (p <0.001), alcohol consumption (p <0.001), increased prevalence of chronic complications of diabetes, and the presence of ketosis. However, the adverse outcomes were not significantly associated with age, duration of diabetes, presence of thyroid disease, or body mass index. Furthermore, planned pregnancy was found to be a significant protective factor (odds ratio, 0.15; p <0.001)., Conclusion: These results indicate that by carefully planning the pregnancy, ensuring optimal glycemic control, and eliminating habitual risk factors, the fetal risk in pregnancies among women with type 1 diabetes may decrease to a value similar to that noted in women without diabetes.

Objectives: To assess the prevalence of metabolic syndrome and evaluate proinflammatory status in patients with type 1 diabetes, and to analyse the relationship between inflammation, metabolic control and insulin resistance in these patients., Methods: Patients with type 1 diabetes were stratified according to the presence or absence of metabolic syndrome. Serum adiponectin, leptin, tumour necrosis factor (TNF)-α, interleukin (IL)-6 and high-sensitivity C-reactive protein (hsCRP) were quantified., Results: The prevalence of metabolic syndrome was 28.6% (22/77). Patients with metabolic syndrome had lower adiponectin concentrations and higher leptin, TNF-α, IL-6 and hsCRP concentrations compared with patients without metabolic syndrome. In addition, metabolic syndrome was associated with higher glycosylated haemoglobin and insulin dose, and increased insulin resistance., Conclusions: The proinflammatory state associated with metabolic syndrome in patients with type 1 diabetes leads to deterioration of glycaemic control and an increase in the required daily dose of insulin. Early and proactive diagnosis of metabolic syndrome in these patients will allow medication and lifestyle optimization, in order to prevent the occurrence of diabetes complications and improve health-related quality-of-life., (© The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

Background and Aims: In order to assess the role played by tubular epithelial cells (TEC) and interstitial vascular endothelial cells (VEC) in interstitial fibrogenesis in human glomerulonephritis, we studied the expression of markers of activated fibroblasts (α-smooth muscle actin (αSMA) and vimentin (Vim)) and of the transforming growth factor β (TGFβ), at the level of these cells., Methods: We studied retrospectively 41 renal biopsies from patients with primary and secondary glomerulonephritis [24 males, 17 females, mean age 45.5 ± 12.9 years]. Immunohistochemistry using monoclonal antibodies (SMA, Vim, TGFβ) was assessed using a semiquantitative score, that was correlated with biological and histological data (quantified using a scoring system in order to assess active-inflammatory and chronic-sclerotic/fibrotic lesions)., Results: The presence of SMA and Vim as markers of myofibroblasts was found in TECs and VECs. TEC Vim expression correlated with interstitial Vim expression (r = 0.38; p = 0.008), interstitial infiltrate (r = 0.31; p = 0.027), interstitial fibrosis (R = 0.25; p = 0.042), GFR (r = -0.35; p = 0.016), SMA (r = -0.42; p = 0.015), TGFβ (r = 0.25; p = 0.046), and hemoglobin (r = -0.55; p < 0.001). VEC Vim expression showed indirect correlations with interstitial infiltrate (r = -0.32; p = 0.023) and interstitial fibrosis (r = -0.34; p = 0.017)., Conclusion: Our study reflects the complexity of the involvement of VEC and mainly of TEC in fibrosis. The expression of mesenchymal markers at the tubular cell level (especially Vim) correlates with histological interstitial changes, with the decrease of renal function and more strongly with anemia.

Objective: Nonalcoholic fatty liver disease represents an excessive fat accumulation in the liver of patients with no other liver disease and no history of alcohol abuse. It is associated with insulin resistance, being more prevalent in obesity and type 2 diabetes. Our aim was to assess the prevalence of fatty liver and nonalcoholic steatohepatitis in patients with type 2 diabetes and to evaluate the influence of obesity on its prevalence., Methods: We included 348 type 2 diabetes patients (age: 18-65 years), without a history of liver disease or alcohol abuse. We assessed demographical data, medical history, physical examination, blood tests, and abdominal ultrasonography., Results: The prevalence of liver steatosis in our group was 87.1 %, with no significant differences between men and women. Patients with steatosis had higher abdominal circumference, body mass index (BMI; p = 0.001), and serum triglyceride (p < 0.0001), HbA1c (p < 0.001), and alaninaminotranspherase levels (ALT, p = 0.001). The value of BMI, abdominal circumference, and serum triglyceride levels independently influenced the prevalence of liver steatosis; the influence of HbA1c level was not significant. In 23.9 % of the patients with steatosis, we found elevated liver enzymes., Conclusion: We observed an elevated prevalence of nonalcoholic fatty liver disease (87.1 %) in type 2 diabetic patients. The factors influencing this prevalence are BMI, abdominal circumference,and serum triglyceride levels.

The paper highlights the importance of tubular lesions of the solitary kidney (SK), identified and monitored by means of urinary biomarkers, mainly N-acetyl-beta-D-glucosaminidase (NAG), albumin, alpha 1-, and beta 2-microglobulin. It is considered that the assessment of a SK should be performed with four and not three parameters as it was usually done until recently: renal function, proteinuria and blood pressure (BP), to which biomarkers should be added. The solitary kidney can result after nephrectomy for kidney transplantation. In some countries living kidney donors represent the only option for performing kidney transplantation. The SK in living donors has generally a good evolution, although sometimes renal injury manifested by proteinuria, arterial hypertension (AH), or diminution of renal function does occur. Therefore, living donors require attentive monitoring. The SK is considered to have a good evolution (even in donors), in spite of alterations of the above-mentioned clinical and biological parameters. The very infrequent cases who evolve progressively towards renal failure are not predictable, which requires monitoring of all persons with a SK. The SK represents a special situation in case of association with a disease affecting the kidney, such as urinary tract infection (UTI), diabetes mellitus, or systemic lupus erythematosus (SLE). Pregnancy occurring in a person with a SK also needs attentive follow-up. Pregnancy associated diseases, such as preeclampsia occurring in patients with a SK, impose appropriate therapeutic behaviour. The SK remains a particular entity in nephrology which needs to be carefully monitored.

Colorectal cancer represents the third cause of cancer. Since its detection in due time is important resolution, appropriate monitoring is mandatory. The present study deals with the relationship between colorectal cancer and renal function, as well as other associated risk factors. Chronic kidney disease (CKD) represents a risk factor of cancer, both in non-dialysed patients and especially in dialysed patients and in patients with renal transplant. It can get aggravated with cancer in general and particularly with colorectal cancer, partly related to the toxins that cannot be appropriately eliminated because of renal functional disturbances. At the same time, immunosuppressive therapy used for treating glomerular or secondary nephropathies represents an important risk factor of cancer. Some patients with colorectal cancer were found to present also impaired renal function, a fact whose significance is still little known. The object of the present paper is an analysis of the case records of a clinic of gastroenterology on the relationship between colorectal cancer and renal functional impairment. We found in the patients with colorectal cancer under study a glomerular filtration rate (GFR calculated with the EPI formula) of < 60 ml/min/1.73m2 in 31/180 patients, respectively 17.22% of the cases, a value that is similar to that in specialised literature. We also analysed associated risk factors that could be related to renal function impairment in these patients: age, gender, anaemia, diabetes mellitus and hypertension. These could represent, together with the colorectal cancer of the investigated patients, risk factors affecting on the one hand renal function, and on the other hand, potentially increasing the risk of cancer. Correction of these risk factors would have beneficial effects on patients. The relationship between renal functional impairment, respectively CKD, and colorectal cancer is to be regarded from the point of view of complex reciprocity: the impairment of the renal function is a factor of risk of colorectal cancer and colorectal cancer can influence renal function of these patients. This report of reciprocity based on important pathogenic mechanisms also interrelates with factors of risk consecutive to both renal function impairment and colorectal cancer.

The solitary kidney (SK) is of special interest for practitioners because of the reduced number of nephrons as compared to persons who have 2 kidneys. It undergoes adaptive phenomena of hypertrophy and hyperfiltration that allow long-term evolution, but pathological situations might occur in the remnant kidney. In some persons with a SK, the adaptive phenomena can be associated with proteinuria, arterial hypertension (AH) and diminished Glomerular Filtration Rate (GFR). In very rare situations, diminution of renal function in patients with a SK can progress to end-stage renal disease (ESRD) and, totally exceptionally, it requires renal replacement therapy. The SK can be congenital or acquired. At present patients with a SK address themselves more and more frequently to nephrology services which monitor the evolution of both the congenital and the surgically acquired SK. The congenital SK possesses a higher number of nephrons (75%, as compared to 2 functional kidneys in a healthy person) than the surgically acquired SK - 50% nephrons. This makes adaptive phenomena differ. Secondary lesions sometimes appear later in case of the congenital SK. In other situations, no significant differences between the evolution of the congenital or acquired SK are registered. The congenital solitary kidney is often associated with congenital abnormalities of the kidney and of the urinary tract (CAKUT). This association increases the risk for chronic kidney disease and for evolution towards chronic renal failure. The congenital SK is also often associated with gynaecological and other abnormalities. The acquired solitary kidney can be due to nephrectomy on a pathological kidney which could not be conservatively treated or due to donation of a kidney for renal transplantation. The SK itself sometimes requires partial nephrectomy intervention, for example sparing surgery. Although the evolution is in most cases favorable, it requires attentive monitoring.

Diabetic nephropathy, one of the most important complications of diabetes mellitus, requires during its evolution protective measures defined as renoprotective. Since the complications of diabetes mellitus are not limited to diabetic nephropathy and as this is frequently associated with heart complications that require protective measures defined as cardioprotective, neurologic measures that require neuroprotection of the retina, of the large vessels etc., much more complex protective measures are necessary. The metabolic complications that are usually at the basis of the other complications at the level of the cell also impose measures of protection. Such an approach can have important practical consequences. It is a well-known fact that most patients with chronic kidney disease--CKD--do not reach final stages as in the meantime they decease because of cardiovascular diseases. Consequently, cardioprotective measures have to be associated with renoprotective ones, as well as protective measures that address other organs, in close connection with protective measures at metabolic level. The protective measures must also address to microcirculation, diabetic nephropathy being a disease that primarily affects microcirculation. Diabetes mellitus also frequently affects the large vessels, the circulatory system being usually affected in its complexity. The paper represents a synthesis of multiorganprotective measures in diabetic nephropathy, in diabetes mellitus, respectively, the concept of multiorgan protection finding in this disease an ideal domain of expression. The first part gives the main multiorgan measures: monitoring of blood pressure and, mainly, protection by means of the renine aldosterone (RAAS) system, multiorgan by intensive monitoring of glycaemia and by treatment of proteinuria. The second part presents the other protective measures used in diabetic nephropathy.

Unlabelled: The purpose of this study is to review our clinical experience with abdominal wound dehiscence in the Surgical Department of City Hospital Timisoara., Patients and Methods: 19.116 abdominal procedures were performed between January 1992 - March 2009 in our Department and 29 complete dehiscences were identified (0,15%). Significant risk factors in our analysis were intraabdominal infection, wound infection, emergency surgery, malignancies, digestive fistulae, hiperabdominal pressure, sex and age over 65 years. Less significant factors were the abdominal type of incision, the method of wound closure and heart or respiratory diseases., Conclusions: postoperative complete dehiscence is a constant presence in a surgical department; despite its low frequency, wound dehiscence is associate with a hight mortality and morbidity rate, and increase the costs and hospitalisation periode. Risk factors evaluation and their associations represente an important role in the therapeutic management of the surgical patient.

Unlabelled: It is well known that sometimes it is difficult to distinguish between type 1 and 2 diabetes mellitus using clinical criteria, in subjects with disease onset relatively early in adult life. The measurement of C peptide level and of immunological markers may represent important additional tools for establishing the correct diagnosis. The aim of the study is to assess the trend of basal C peptide in patients with clinical diagnosis of type 2 diabetes and to relate it to the type of treatment, the body weight and the positivity for pancreatic autoantibodies., Patients and Method: we studied a group of 268 patients with type 2 diabetes, aged between 30 and 50 years, with a diabetes duration of less than 5 years. In all patients, we measured basal C peptide, islet cell autoantibodies and antibodies against glutamic acid decarboxylase, computed the body mass index and recorded the current antidiabetic treatment., Results: Based on basal C peptide value, diabetic subjects fell under 3 categories: a) low C peptide (<0.58 ng/ml): 7.5%, b) normal C peptide (0.58-2.70 ng/ml): 57.8%, and c) high C peptide (>2.70 ng/ml): 34.7%. Patients with low C peptide were treated more often with insulin, while those in high C peptide group received more often biguanides. A direct correlation between C peptide and body weight was established. Mean C peptide was lower in patients positive for at least one pancreatic autoantibody, compared to those who were negative for antibodies, Conclusion: Low basal C peptide can be considered criterion for transferring the patients, initially diagnosed as type 2 diabetes, in the type 1 diabetes group.
