Abstract Background Kidney disease is associated with an increased total mortality and cardiovascular morbimortality in the general population and in patients with Type 2 diabetes. The aim of this study is to determine the prevalence of kidney disease and different types of renal disease in patients with type 2 diabetes (T2DM). Methods Cross-sectional study in a random sample of 2,642 T2DM patients cared for in primary care during 2007. Studied variables: demographic and clinical characteristics, pharmacological treatments and T2DM complications (diabetic foot, retinopathy, coronary heart disease and stroke). Variables of renal function were defined as follows: 1) Microalbuminuria: albumin excretion rate & 30 mg/g or 3.5 mg/mmol, 2) Macroalbuminuria: albumin excretion rate & 300 mg/g or 35 mg/mmol, 3) Kidney disease (KD): glomerular filtration rate according to Modification of Diet in Renal Disease < 60 ml/min/1.73 m2 and/or the presence of albuminuria, 4) Renal impairment (RI): glomerular filtration rate < 60 ml/min/1.73 m2, 5) Nonalbuminuric RI: glomerular filtration rate < 60 ml/min/1.73 m2 without albuminuria and, 5) Diabetic nephropathy (DN): macroalbuminuria or microalbuminuria plus diabetic retinopathy. Results The prevalence of different types of renal disease in patients was: 34.1% KD, 22.9% RI, 19.5% albuminuria and 16.4% diabetic nephropathy (DN). The prevalence of albuminuria without RI (13.5%) and nonalbuminuric RI (14.7%) was similar. After adjusting per age, BMI, cholesterol, blood pressure and macrovascular disease, RI was significantly associated with the female gender (OR 2.20; CI 95% 1.86–2.59), microvascular disease (OR 2.14; CI 95% 1.8–2.54) and insulin treatment (OR 1.82; CI 95% 1.39–2.38), and inversely associated with HbA1c (OR 0.85 for every 1% increase; CI 95% 0.80–0.91). Albuminuria without RI was inversely associated with the female gender (OR 0.27; CI 95% 0.21–0.35), duration of diabetes (OR 0.94 per year; CI 95% 0.91–0.97) and directly associated with HbA1c (OR 1.19 for every 1% increase; CI 95% 1.09–1.3). Conclusions One-third of the sample population in this study has KD. The presence or absence of albuminuria identifies two subgroups with different characteristics related to gender, the duration of diabetes and metabolic status of the patient. It is important to determine both albuminuria and GFR estimation to diagnose KD.

Aim. To assess prescribing practices of noninsulin antidiabetic drugs (NIADs) in T2DM with several major contraindications according to prescribing information or clinical guidelines: renal failure, heart failure, liver dysfunction, or history of bladder cancer. Methods. Cross-sectional, descriptive, multicenter study. Electronic medical records were retrieved from all T2DM subjects who attended primary care centers pertaining to the Catalan Health Institute in Catalonia in 2013 and were pharmacologically treated with any NIAD alone or in combination. Results. Records were retrieved from a total of 255,499 pharmacologically treated patients. 78% of patients with some degree of renal impairment (glomerular filtration rate (GFR) < 60 mL/min) were treated with metformin and 31.2% with sulfonylureas. Even in the event of severe renal failure (GFR < 30 mL/min), 35.3% and 22.5% of patients were on metformin or sulfonylureas, respectively. Moreover, metformin was prescribed to more than 60% of patients with moderate or severe heart failure. Conclusion. Some NIADs, and in particular metformin, were frequently used in patients at high risk of complications when they were contraindicated. There is a need to increase awareness of potential inappropriate prescribing and to monitor the quality of prescribing patterns in order to help physicians and policymakers to yield better clinical outcomes in T2DM.

Aim: The aim of this study was to assess glycaemic control and prescribing practices of antihyperglycaemic treatment in patients with diabetes mellitus type 2 aged 75 years or older.Methods: We analysed data from health electronic records from 4,581 persons attended at primary healthcare centres of the Institut Català de la Salut (ICS), in the Girona Sud area of Catalonia, Spain, during 2013 and 2016. Variables such as age, gender, body mass index (BMI), diabetes duration, age at diabetes diagnosis, glycated haemoglobin (HbA1c), creatinine, glomerular filtrate rate and the albumin/creatinine ratio in urine were collected. A descriptive analysis of the study variables was done to determinate the percentage of persons on antidiabetic treatment.Results: We identified 4,421 persons aged 75 years or older who provided data on HbA1c and antidiabetic treatment. Mean age was 82.3 (5.1) years. In 58.1% of patients, the level of HbA1c was below 7.0%, while in 36.8% it was below 6.5%. Between patients with HbA1c below 7.0%, antidiabetic drugs were taken by 70.2%, where 15.2% were either on insulin, sulphonylureas or repaglinide therapy.Conclusion: Intensive treatment among older adults with diabetes mellitus type 2 is common in primary care clinical practice in our area. Intensive glycaemic control confers an increased risk of hypoglycaemia and little benefit among older individuals with diabetes. Physicians should take care more not to harm those populations and treatment should be de-intensified to reduce the risk of hypoglycaemia. [ABSTRACT FROM AUTHOR]

Background: The presence of chronic kidney disease (CKD) in type 2 diabetes mellitus (T2DM) increases the risk of cardiovascular disease (CVD) regardless of the presence of traditional cardiovascular risk factors. There is controversy about the impact of each of the manifestations of CKD on the prevalence of CVD, whether it is greater with decreased estimated glomerular filtration rate (eGFR) or increased urine albumin creatinine ratio (UACR). Methods: This study is a national cross-sectional study performed in primary care consults. We selected participants of both sexes who were aged 40 years or older, had been diagnosed with T2DM and had complete information on the study variables recorded in their medical records. The participants were classified according to eGFR : ≥ 60; 45–59; 30–44; <30 mL/min/1.73 m22 and UACR : < 30; 30–299; ≥300 mg/gr. The results were adjusted to compare the prevalence of CVD across all categories. Results: A total of 1141 participants were included. Compared to participants with eGFR > 60 mL/min/1.73 m2 those with eGFR between 30–44 mL/min/m22, (OR = 2.3; 95% CI, 1.4-3.9); and eGFR < 30 mL/min/1.73 m22 (OR = 4.1 95% CI 1.6-10.2) showed increased likelihood of having CVD. Participants with UACR ≥ 30 mg/g compared to participants with UACR < 30 mg/g increased significantly the likelihood of having CVD, especially with UACR above 300 mg/g, (OR = 1.6; 95% CI 1.1-2.4 for UACR = 30–299 mg/g; OR = 3.9; CI 1.6-9.5 for UACR ≥ 300 mg/g). Conclusion: The decrease in eGFR and increase in UACR are independent risk factors that increase the prevalence of CVD in participants with T2DM and these factors are independent of each other and of other known cardiovascular risk factors. In our study the impact of mild decreased eGFR in T2DM on CVD was lower than the impact of increased UACR. It is necessary to determine not only UACR but also eGFR for all patients with T2DM, both at the time of diagnosis and during follow-up, to identify those patients at high risk of cardiovascular complications.

Bakground: The objective of this study was to determinate the prevalence of chronic kidney disease (CKD) and the different stages of CKD in patients with type 2 diabetes mellitus (DM2) treated in primary care consults in Spain. Methods: A national cross-sectional study was performed in primary care consults. The following data were collected: demographic and anthropometric information; list of present cardiovascular risk factors (CVRF); previous macrovascular and microvascular disease history; physical examination and analytical data from the previous 12 months, including the urine albumin-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) to evaluate renal function. Results: With regard to the patients, 27.9% presented some degree of CKD as follows: 3.5% with stage 1; 6.4% with stage 2; 16.8% with stage 3 (11.6% with stage 3A and 5.2% with stage 3B); and 1.2% with stages 4 and 5. The prevalence of patients with UACR = 30 mg/g was 15.4% (13% microalbuminuria and 2.4% macroalbuminuria). Renal impairment (RI) was found in 206 patients (18%) of whom 133 patients (64.6%) was stage 3A, 60 patients (29.1%) was stage 3B and 13 patients (6.3%) stages 4 and 5. Among patients with RI, 143 patients (69.4%) had normoalbuminuria. The following variables were significantly associated with CKD: age; sex (women); systolic arterial blood pressure (SABP) = 150 mmHg; and a previous history of cardiovascular disease. Conclusions: The results showed that the prevalence for any type of CKD was 27.9%. A systematic determination of UACR and eGFR may contribute to an early diagnosis, thus allowing intervention during the initial stages of the disease when treatment is more efficient.

BackgroundTo determine the prognostic value of various self-blood pressure (BP) monitoring (SBPM) cutoff at the time of diagnosis.MethodsCohort of 466 newly diagnosed and never-treated hypertensive patients. At baseline and at 1 year, the patients underwent a physical examination, clinic BP (CBP), SBPM, and ambulatory BP monitoring (ABPM), fasting blood and urine analysis, electrocardiogram (ECG), and retinography. The diagnosis of hypertension was made based on CBP average of two readings, separated by 2 min, taken over three different days, with results ≥140/90 mm Hg. At 1-year follow-up, target organ damage (TOD) evolution was classified as favorable or unfavorable.ResultsMean age was 57.4 years, 56.8% were men. Adjusted multivariate analysis showed that hypertensive patients with baseline SBPM <135/85 mm Hg had a more favorable evolution of left ventricular hypertrophy (LVH) (odds ratio (OR): 1.9; 95% confidence interval (CI): 1.5-2.5), high urinary albumin excretion rate (UAER) (OR: 6.9; 95% CI: 3.4-14.4), and more favorable amount of TOD evolution (OR: 1.7; 95% CI: 1.4-2.0) than those with baseline SBPM ≥135/85 mm Hg. Patients with baseline SBPM <130/80 mm Hg, or <125/80 mm Hg had a more favorable evolution of the amount of TOD (OR: 2.7; 95% CI: 2.0-3.6, and OR: 2.9; 95% CI: 2.1-4.1, respectively) at 1 year than those with baseline SBPM <135/85 mm Hg.ConclusionsBaseline SBPM values <130/80 mm Hg is associated with better evolution of amount of TOD than SBPM values <135/85 mm Hg. These results would support a clinical trial to test a SBPM threshold <130/80 as an optimal pressure not needing pharmacological treatment among those with CBP ≥140/90.American Journal of Hypertension 2012; doi:10.1038/ajh.2012.126 [ABSTRACT FROM AUTHOR]

Background. The aim is to evaluate whether cardiovascular (CV) risk stratification in newly diagnosed hypertensive patients according to the European Society of Hypertension (ESH) guidelines, can predict the evolution of target organ damage (TOD) using routine examinations in clinical practice during 1 year. Methods. Prospective study of recently diagnosed untreated hypertensives. At the moment of inclusion and 1 year later, urinary albumin excretion rate (UAER), blood analysis, electrocardiogram, retinography, self-monitored blood pressure (BP) and ambulatory BP measurement were performed. TOD was defined following the ESH guidelines and evaluated as having favorable or unfavorable evolution. Results. Four hundred and seventy-nine hypertensive patients were included (58.8 years; 43.4% women). The baseline prevalence of TOD was: high UAER (2.4%), left ventricular hypertrophy (LVH) (20.7%), advanced lesion of the fundus oculi (FO) (10.2%). After 1 year, no differences were found between the final systolic and diastolic BP neither in the high/very high nor in the low/moderate CV risk groups. Patients with low/moderate CV risk had less unfavorable TOD evolution, LVH (9.2% vs 41.7%; p <0.001), FO advanced damage (0.99% vs 14.3%; p <0.001), high UAER (0.3% vs 5.1%; p <0.005) and amount of TOD (9.2% vs 44.0%; 0<0.001) than those with high/very high CV risk. The odds ratios of favorable TOD evolution adjusted for BP change and antihypertensive drug treatment were (low/moderate vs high/very high CV risk); 5.14 (95% confidence interval, CI, 3.99-6.64) for LVH; 12.42 (6.67-23.14) FO advanced damage; 10.71 (3.67-31.22) high UAER and 13.99 (10.18-19.22) for amount of TOD. Conclusions. It is possible to detect variations in TOD in hypertensive patients with a 1-year follow-up using the examinations available in routine clinic practice. The risk determined by the ESH guidelines predicts the evolution of TOD at 1 year. [ABSTRACT FROM AUTHOR]

Background: Some authors consider that secondary prevention should be conducted for all DM2 patients, while others suggest that the drug preventive treatment should start or be increased depending on each patient's individual CVR, estimated using cardiovascular or coronary risk functions to identify the patients with a higher CVR. The principal objective of this study was to assess three different cardiovascular risk prediction models in type 2 diabetes patients.Methods: Multicentre, cross-sectional descriptive study of 3,041 patients with type 2 diabetes and no history of cardiovascular disease. The demographic, clinical, analytical, and cardiovascular risk factor variables associated with type 2 diabetes were analysed. The risk function and probability that a cardiovascular disease could occur were estimated using three risk engines: REGICOR, UKPDS and ADVANCE. A patient was considered to have a high cardiovascular risk when REGICOR ≥ 10 % or UKPDS ≥ 15 % in 10 years or when ADVANCE ≥ 8 % in 4 years.Results: The ADVANCE and UKPDS risk engines identified a higher number of diabetic patients with a high cardiovascular risk (24.2 % and 22.7 %, respectively) compared to the REGICOR risk engine (10.2 %). The correlation using the REGICOR risk engine was low compared to UKPDS and ADVANCE (r = 0.288 and r = 0.153, respectively; p < 0.0001). The agreement values in the allocation of a particular patient to the high risk group was low between the REGICOR engine and the UKPDS and ADVANCE engines (k = 0.205 and k = 0.123, respectively; p < 0.0001) and acceptable between the ADVANCE and UKPDS risk engines (k = 0.608).Conclusions: There are discrepancies between the general population and the type 2 diabetic patient-specific risk engines. The results of this study indicate the need for a prospective study which validates specific equations for diabetic patients in the Spanish population, as well as research on new models for cardiovascular risk prediction in these patients.

Background and Objective: International guides of hypertension (HT) recommend self-blood -pressure-measurement (SBPM) values higher than 135/85 mmHg to determine isolated clinical hypertension (ICH). This paper suggests a lower cut-off., Patients and Method: This prospective, protocol-based study included 378 patients, 250 new hypertensive patients without previous treatment. Both SBPM and ambulatory blood pressure monitoring (ABPM) were measured in all patients. Risk factors and target organ disease (TOD) were evaluated by electrocardiography, renal function, microalbuminuria and retinography., Results: With a 135/85 mmHg ICH cut-off, only differences in serum creatinine levels (78.67 ICH vs 83.98 micromol/l sustained HT -SHT-; p = 0.03), grade I/II fundus oculi (FO) lesions (44.7 vs 62.8%; p = 0.009) and any FO lesions (48.2 vs 67.4%; p = 0.005) were found. With a ICH cut-off of 130/80 mmHg, a lower risk of grade III/IV FO lesions was found (RR = 0.59; 90% confidence interval [CI], 0.36-0.96; p = 0.06). Any TOD risk was related to SHT with a 130/85 mmHg cut-off (RR = 12.04; 90% CI, 1.03-140.28; p = 0.09)., Conclusions: Taking a 135/85 mmHg ICH cut-off, no differences in TOD between ICH and SHT were found. Taking a 130 mmHg ICH systolic blood pressure (SBP) cut-off, those who are below 130 mmHg have a lower risk of grade III/IV FO lesions. Those who are above this value have a higher TOD risk. Looking at TOD risk, we should consider a < 130 mmHg SBP cut-off for ICH diagnosis.
