[Thrombophilic study in dialysis patients].

Chronic kidney disease is a complex phenotype that results from the association of underlying kidney disease and environmental and genetic factors. In addition to the traditional risk factors, genetic factors are involved in the etiology of renal disease, including single nucleotide polymorphisms which could account for the increased mortality from cardiovascular disease of our hemodialysis patients. The genes that influence the development and rate of progression of kidney disease deserve to be better defined. We have evaluated the alterations of thrombophilia genes in hemodialysis patients and in blood donors and we have compared the results obtained. The objective of the present study is to identify biomarkers of morbidity and mortality, which allow us to identify patients with chronic kidney disease at high risk, thanks to which it is possible to implement accurate therapeutic strategies and preventive strategies that have the objective of intensifying controls in these patients.

[Intoxications in nephrology: clinical cases and local experience in Sciacca Hospital].

Intoxications are a common problem all over the world and cause acid-base balance disturbances, dysionias or acute renal failure; they can develop rapidly leading to severe cellular dysfunction and death. Intoxications and drug overdoses often require the intervention of Nephrologists, for the correction of acidosis, the administration of selective inhibitory enzymes and also hemodialysis treatment. Extracorporeal therapies have been used to remove toxins for over fifty years and have acquired an increasing role, thanks to the use of new treatment modalities in intoxicated patients. In our clinical practice in the Covid period we have found an increase in clinical cases of intoxication with psychiatric drugs, including benzodiazepines, clozapine, lithium, quetiapine and cocaine.

[Urinary tract infections in nephrology: antibiotic therapy in the era of antibiotic resistance].

Urinary tract infections (UTIs) are an emerging health problem. Kidney patients with UTI are at increased risk of antimicrobials resistance (AMR) and bad prognosis. In the nephrological setting, optimizing the management of UTIs is certainly a challenge, but it is indispensable for a favorable clinical outcome and in fighting AMR. When UTIs caused by multidrug-resistant germs are suspected, it is necessary to initiate empirical antibiotic therapy timely, pending microbiological study and bacterial sensitivity. The empirical choice of antibiotic must be based on: guidelines, resistance rates recorded in the region, and knowledge of pharmacokinetic and pharmacodynamic characteristics of the drug, in order to maximize efficacy, reduce adverse effects and minimize AMR development. Recently, the clinical use of old drugs such as colistin has increased, due to the limited circulation of resistant bacterial strains. On the other hand, ceftolozane/tazobactam, ceftazidime/avibactam, cefiderocol, imipenem/cilastatin/relebactam and meropenem-vaborbactam are very promising new antibiotics. Ongoing clinical studies will be able to determine the place for these interesting molecules in the treatment of infections and in fighting AMR.

[GLP-1 receptor agonists in the treatment of diabetes mellitus type 2: cardioprotection, and more!]

Optimal glycemic control in diabetic patients remains a difficult goal to achieve. Hypoglycemia, nausea and weight gain can compromise the patients' adherence to antidiabetic therapy over time. GLP-1 receptor agonists have been shown to improve glycemic control and reduce the incidence of side effects both when used in monotherapy and in combination with other hypoglycemic drugs. The growing interest of nephrologists in GLP-1 receptor agonists derives from numerous studies showing that not only they positively affect traditional cardiovascular risk factors, but also exert a protective effect on renal function regardless of their hypoglycemic effects, thus delaying the development and progression of diabetic nephropathy. The aim of this paper is to review the latest evidence on pharmacokinetics and pharmacodynamics and the direct and indirect mechanisms through which GLP-1 receptor agonists confer nephroprotection, improving the renal outcomes of diabetic patients.

Health-related quality of life (HRQoL) in a population at risk of type 2 diabetes: a cross-sectional study in two Latin American cities.

PURPOSE: The purpose of this study was to describe the health-related quality of life (HRQoL) characteristics in a population at risk of developing type 2 diabetes in Barranquilla and Bogotá, Colombia. METHODS: A cross-sectional study with 1135 participants older than 30 years-of-age recruited in Bogotá D.C., and Barranquilla by cluster sampling in 2018 to 2019. The Finnish Diabetes Risk Score (FINDRISC) was used to detect participants at risk of developing type 2 diabetes (T2D). HRQoL was assessed using the EQ-5D-3L questionnaire. Unadjusted and adjusted logistic regression models were used to calculate odds ratios (OR) and their corresponding 95% confidence intervals CI). RESULTS: Moderate or extreme problems appeared more frequently in the dimensions of Pain/Discomfort (60.8%) and Anxiety/Depression (30.8%). The mean score of the EQ-VAS was 74.3 (± 17.3), significantly larger in the state of complete health (11111) compared with those with problems in more than one of the quality-of-life dimensions. Being female and living in Bogota D.C., were associated with greater odds of reporting problems in the Pain (OR 1.6; 95% CI 1.2-2.2) and Discomfort dimensions (OR 1.6; 95% CI 1.2-2.0) respectively and Anxiety/Depression (OR 1.9; 95% CI 1.3-2.7), (OR 9.1; 95% CI 6.6-12.4), respectively. CONCLUSIONS: As living place and sex were associated with dimensions of Pain/Discomfort and Anxiety/Depression in the HRQoL in people at risk of T2D, greater attention should be paid to these determinants of HRQoL to design and reorient strategies with a territorial and gender perspective to achieve better health outcomes. Diabetes is one of the four non-communicable diseases with increasing prevalence in the world, which has made it a serious public health problem. In Colombia, in 2019 diabetes affected 8.4% of the Colombian adult population and more than one million Colombian adults of this age group have hidden or undetected diabetes. This disease is not only characterized by increased premature mortality, loss of productivity, and economic impact, but it also involves a deterioration in the quality of life of people with diabetes with their respective families. However, very Little is known about health-related quality of life (HRQoL) in a population at risk or with prediabetes. This study has evaluated the quality of life in patients at risk of diabetes and their behavior with some variables as sociodemographic, lifestyle, history, and established their difference in two territories of the Colombian Caribbean. The results of this study indicate that the HRQoL of people at risk of type 2 diabetes is affected by factors such as gender, city, dysglycemia, medication for hypertension and education level. Therefore, greater attention should be paid to these determinants of HRQL to design and implement strategies that reduce this risk of developing type 2 diabetes, prevent prediabetes and improve the quality of life in prediabetic or diabetic patients.

Factors Associated With Low Physical Activity in Two Latin American Populations at Risk of Developing Type 2 Diabetes: An Exploratory Analysis.

Low level of physical activity is a risk factor for chronic non-communicable diseases. Specifically, people at risk of Type 2 Diabetes (T2D) have shown to benefit from being physically active. The objective of this study was to explore what factors were associated with low physical activity in people at high risk of T2D living in Bogota and Barranquilla, Colombia. Methodology: Cross-sectional study using baseline data from a quasi-experimental clinical trial (PREDICOL Project). The study included 1,135 participants of Bogota and Barranquilla that presented a high risk of developing T2D according to the Finnish Diabetes Risk Score (>12 points) and who underwent an oral glucose tolerance test. The main outcome variable was the level of physical activity assessed by the International Physical Activity Questionnaire. Unadjusted and adjusted logistic regression analysis were used to calculate odds ratios (OR) and the corresponding 95% confidence intervals (CI). Results: In total, 72.5% of the study participants had low level of physical activity. Participants in the age group between 45 and 54 years showed 74% greater odds of having low physical activity compared with the youngest age group (OR 1.74, 95% CI 1.1 -2.8). People living in Barranquilla were eight times more likely to have low physical activity compared with those in Bogotá D.C. (OR 8.1, 95% CI 5.7 to 11.4). Conclusion: A large proportion of the population at risk of developing D2T in two large cities of Colombia have a sedentary lifestyle. Interventions should be designed and implemented in order to increase physical activity in these populations.

[Antifibrotic renal role of mineralcorticoid receptor antagonists].

Cardiovascular and renal diseases are one of the main health problems in all industrialized countries. Their incidence is constantly increasing due to the aging of the population and the greater prevalence of obesity and type 2 diabetes. Clinical evidence suggests that aldosterone and the activation of mineralocorticoid receptors (MR) have a role in the pathophysiology of cardiovascular and renal diseases. Moreover, clinical studies demonstrate the benefits of mineralocorticoid receptor antagonists (MRAs) on mortality and progression of heart and kidney disease. In addition to renal effects on body fluid homeostasis, aldosterone has multiple extrarenal effects including the induction of inflammation, vascular rigidity, collagen formation and stimulation of fibrosis. Given the fundamental role of MR activation in renal and cardiac fibrosis, effective and selective blocking of the signal with MRAs can be used in the clinical practice to prevent or slow down the progression of heart and kidney diseases. The aim of the present work is to review the role of MRAs in light of the new evidence as well as its potential use as an antifibrotic in chronic kidney disease (CKD). The initial clinical results suggest that MRAs are potentially useful in treating patients with chronic kidney disease, particularly in cases of diabetic nephropathy. We don't yet have efficacy and safety data on the progression of kidney disease up to the end stage (ESRD) and filling this gap represents an important target for future trials.
