          Abstract

          Abstract Background: permissibility in the selection of living kidney donors (LKD) with one or more cardiometabolic risk factors (CMRFs) and/or metabolic syndrome (MS) is an increasingly frequent practice worldwide. These factors, together with kidney donation specifically, are known to be associated with an increased risk of chronic kidney disease (CKD). Methods: we analyzed the frequency of CMRFs and MS before and after kidney donation in LKD. In the secondary analysis, we associated CMRFs and MS with renal function. The SPSS V22.0 software was used. Results: we analyzed 110 LKD patients, with a mean age of 35.05 ± 10.5 years: 63 (57.3 %) men and 47 (42.7 %) women. Patients were followed for 25 ± 17.48 months after nephrectomy. Prior to donation, 62 patients (56.4 %) had MS, and the presence of one to six CMRFs was 19.1 %, 32 %, 18.2 %, 17.3 %, 3.6 %, and 0.9 %, respectively. During follow-up, in donors, the incidence of overweight increased from 48.2 % to 52.7 %, (p < 0.01); that of obesity increased from 11.8 % to 20.9 % (p < 0.01); that of hyperuricemia increased from 17.3 % to 26.4 %, (p < 0.01); that of hypercholesterolemia increased from 24.5 % to 33.6 % (p < 0.01); and that of hypertriglyceridemia increased from 47.3 % to 50.9 % (p < 0.01), while the incidence of MS decreased from 56.4 % to 51.8 % (p < 0.01). A logistic regression analysis showed that the presence of CMRFs did not show any association with glomerular filtration rates below 60 mL/min/1.73 m2. Conclusion: LKD had a high frequency of CMRFs and MS at the time of donation, and over time, the incidence of CMRFs significantly increased. Because these factors, together with kidney donation, could be associated with an increased risk of CKD, we must evaluate protocols for LKD and consider stricter criteria in the selection of LKD, with an emphasis on follow-up protocols to address CMRFs and MS.

          Resumen Introducción: la permisibilidad en la selección de los donantes renales vivos (DRV) con uno o más factores de riesgo cardiometabólico (FRCM) y/o síndrome metabólico (SM) es una práctica cada vez más frecuente en todo el mundo. Se sabe que estos factores, junto con la donación de riñón, específicamente, están asociados con un mayor riesgo de enfermedad renal crónica (ERC). Métodos: analizamos la frecuencia de los FRCM y SM antes y después de la donación renal en DRV. En el análisis secundario, asociamos los FRCM y la SM con la función renal. Se utilizó el programa SPSS V22.0. Resultados: se analizaron 110 DRV con una edad media de 35,05 ± 10,5 años: 63 (57,3 %) hombres y 47 (42,7 %) mujeres. Los pacientes fueron seguidos durante 25 ± 17,48 meses después de la nefrectomía. Antes de la donación, 62 pacientes (56,4 %) tenían SM y la presencia de uno a seis FRCM era del 19,1 %, 32 %, 18,2 %, 17,3 %, 3,6 % y 0,9 %, respectivamente. Durante el seguimiento, en los donantes, la incidencia del sobrepeso aumentó del 48,2 % al 52,7 % (p < 0,01); la de la obesidad pasó del 11,8 % al 20,9 % (p < 0,01); la de la hiperuricemia aumentó del 17,3 % al 26,4 % (p < 0,01); la de la hipercolesterolemia aumentó del 24,5 % al 33,6 % (p < 0,01); y la de la hipertrigliceridemia aumentó del 47,3 % al 50,9 % (p < 0,01), mientras que la incidencia del SM disminuyó del 56,4 % al 51,8 % (p < 0,01). El análisis de regresión logística mostró que la presencia de FRCM no presentaba ninguna asociación con las tasas de filtración glomerular por debajo de 60 ml/min/1,73 m2. Conclusión: los DRV tuvieron una alta frecuencia de FRCM y SM en el momento de la donación y, con el tiempo, la incidencia aumentó significativamente. Debido a que estos factores, junto con la donación de riñón, podrían estar asociados a un mayor riesgo de ERC, debemos evaluar los protocolos de los DRV y considerar criterios más estrictos en la selección de estos donantes, haciendo énfasis en los protocolos de seguimiento para tratar los FRCM y el SM.

          Chronic kidney disease: global dimension and perspectives.

          Chronic kidney disease is defined as a reduced glomerular filtration rate, increased urinary albumin excretion, or both, and is an increasing public health issue. Prevalence is estimated to be 8-16% worldwide. Complications include increased all-cause and cardiovascular mortality, kidney-disease progression, acute kidney injury, cognitive decline, anaemia, mineral and bone disorders, and fractures. Worldwide, diabetes mellitus is the most common cause of chronic kidney disease, but in some regions other causes, such as herbal and environmental toxins, are more common. The poorest populations are at the highest risk. Screening and intervention can prevent chronic kidney disease, and where management strategies have been implemented the incidence of end-stage kidney disease has been reduced. Awareness of the disorder, however, remains low in many communities and among many physicians. Strategies to reduce burden and costs related to chronic kidney disease need to be included in national programmes for non-communicable diseases. Copyright © 2013 Elsevier Ltd. All rights reserved.

            Chronic kidney disease.

            Chronic kidney disease is a general term for heterogeneous disorders affecting kidney structure and function. The 2002 guidelines for definition and classification of this disease represented an important shift towards its recognition as a worldwide public health problem that should be managed in its early stages by general internists. Disease and management are classified according to stages of disease severity, which are assessed from glomerular filtration rate (GFR) and albuminuria, and clinical diagnosis (cause and pathology). Chronic kidney disease can be detected with routine laboratory tests, and some treatments can prevent development and slow disease progression, reduce complications of decreased GFR and risk of cardiovascular disease, and improve survival and quality of life. In this Seminar we discuss disease burden, recommendations for assessment and management, and future challenges. We emphasise clinical practice guidelines, clinical trials, and areas of uncertainty.

              Body mass index and risk for end-stage renal disease.

              Although interest in the relationship between obesity and kidney disease is increasing, few epidemiologic studies have examined whether excess weight is an independent risk factor for end-stage renal disease (ESRD). To determine the association between increased body mass index (BMI) and risk for ESRD. Historical (nonconcurrent) cohort study. A large integrated health care delivery system in northern California. 320,252 adult members of Kaiser Permanente who volunteered for screening health checkups between 1964 and 1985 and who had height and weight measured. The authors ascertained ESRD cases by matching data with the U.S. Renal Data System registry through 2000. A total of 1471 cases of ESRD occurred during 8,347,955 person-years of follow-up. Higher BMI was a risk factor for ESRD in multivariable models that adjusted for age, sex, race, education level, smoking status, history of myocardial infarction, serum cholesterol level, urinalysis proteinuria, urinalysis hematuria, and serum creatinine level. Compared with persons who had normal weight (BMI, 18.5 to 24.9 kg/m2), the adjusted relative risk for ESRD was 1.87 (95% CI, 1.64 to 2.14) for those who were overweight (BMI, 25.0 to 29.9 kg/m2), 3.57 (CI, 3.05 to 4.18) for those with class I obesity (BMI, 30.0 to 34.9 kg/m2), 6.12 (CI, 4.97 to 7.54) for those with class II obesity (BMI, 35.0 to 39.9 kg/m2), and 7.07 (CI, 5.37 to 9.31) for those with extreme obesity (BMI > or = 40 kg/m2). Higher baseline BMI remained an independent predictor for ESRD after additional adjustments for baseline blood pressure level and presence or absence of diabetes mellitus. Primary analyses were based on single measurements of exposures. High BMI is a common, strong, and potentially modifiable risk factor for ESRD.
