ABSTRACT
The aim of this study was to investigate the efficacy of physical exercise in chronic kidney disease, describing its impact on the Klotho-FGF23 axis. PubMed, Web of Science and Scopus databases, updated to January 2023, were searched. The present study employed mean difference and a 95% confidence interval (CI) to examine the efficacy of the intervention. Heterogeneity was assessed through inconsistency statistics (I2). Out of the 299 studies identified, a total of 4 randomized controlled trials (RCTs), comprising 272 participants, met the eligibility criteria. Compared with the control group, physical exercise significantly decreased the concentrations of FGF23 (MD: -102.07 Pg/mL, 95% CI: -176.23.47, -27.91 I2= 97%, p = 0.001), and a significantly increased the concentrations of Klotho protein: (MD: 158.82 Pg/mL, 95% CI: 123.33, -194.31, I2 = 0%, p = 0.001). The results of our study indicated that the exercise has a direct relationship with Klotho-FGF23 axis. We can conclude that physical exercise in patients with CKD produces beneficial effects on the pathophysiological components related to this disease, including cardiorespiratory fitness and vascular functions. As observed, both endurance and aerobic physical exercise increase Klotho production and decrease FGF23 levels. Evidence indicates that exercise attenuates the progression of CKD, improves uremic parameters and down-regulates inflammation-related markers.

ABSTRACT Background/Aim: Chronic kidney failure is frequently related to malnutrition. This research aimed to assess the nutritional status of hemodialysis patients by assessing their biochemical and anthropometric parameters and determining whether the disorders suffered stemmed from nutritional deterioration directly related to time on dialysis. Materials and Methods: This research monitored 90 patients of both genders with chronic kidney failure who regularly received hemodialysis at the kidney unit of our Hospital in Granada (Spain) over five years. The patient's blood was tested quarterly for plasma albumin (Alb), total cholesterol (TC), and total proteins (TP) and monthly for transferrin (Tr). Anthropometric measurements were taken of the patient's weight, height, and body mass index (BMI) and, based on the patient's BMI, classified as established by the World Health Organization. Results: During the five years of our study, patients experienced a statistically significant decrease in total protein (0.941g/dl), plasma albumin (0.9382g/dl), total cholesterol (23.77mg/dl), and transferrin (78.17. g/dl) p < 0.0001. On the contrary, the mean BMI values did not show statistically relevant differences (p < 0.805). However, all patients remained in the WHO category of overweight. The body volume values did not show statistically significant differences either. Conclusions: In conclusion, the nutritional deterioration of these patients was not reflected in their BMI but mainly in their serum chemistry.
RESUMEN Antecedentes/Objetivo: La insuficiencia renal crónica está relacionada frecuentemente con la malnutrición, afectando aproximadamente a un tercio de los pacientes con enfermedad renal avanzada, lo que contribuye a su morbilidad y mortalidad. El objetivo de esta investigación fue evaluar el estado nutricional de los pacientes en hemodiálisis valorando sus parámetros bioquímicos y antropométricos y determinar si los trastornos que padecían se debían al deterioro nutricional directamente relacionado con el tiempo en diálisis. Materiales y Métodos: Es esta investigación realizó un seguimiento de 90 pacientes de ambos sexos con insuficiencia renal crónica, que recibían hemodiálisis periódicamente en la unidad renal de nuestro Hospital en Granada (España) durante un período de cinco años. La sangre de los pacientes se analizó trimestralmente para albúmina plasmática (Alb), colesterol total (TC) y proteínas totales (TP), y mensualmente para transferrina (Tr). Se tomaron medidas antropométricas de peso, talla e índice de masa corporal (IMC) de los pacientes y se les efectuaron mediciones antropométricas de peso, altura e índice de masa corporal calculado mediante la formula peso/talla², y agrupada según la clasificación de la OMS en IMC < 18.50 infrapeso, 18.50 a 24,99 normal, 25 a 29,99 sobrepeso y >30 del IMC s/OMS y se consideró para el estudio como desnutrición un en IMC < 23 kg/m2 y niveles de albumina <3,8 g/dl según el consenso del panel de expertos de la International Society for Renal Nutrition and Metabolism. Resultados: Durante los cinco años de nuestro estudio, los pacientes experimentaron una disminución estadísticamente significativa de proteínas totales (0,941 g/dl), albúmina plasmática (0,9382 g/dl), colesterol total (23,77 mg/dl) y transferrina (78,17. g /dl) p < 0,0001. Por el contrario, los valores medios del IMC no mostraron diferencias estadísticamente relevantes (p < 0,805). Sin embargo, todos los pacientes permanecieron en la categoría de sobrepeso de la OMS. Los valores de volumen corporal tampoco mostraron diferencias estadísticamente significativas. Conclusiones: La desnutrición de los pacientes en diálisis es un hecho patente, el IMC no se corresponde con los parámetros bioquímicos observados, por lo que el deterioro nutricional de estos pacientes se manifiesta principalmente mediante los parámetros bioquímicos estudiados.
ABSTRACT
A case report of an 11-year-old boy with a de novo variant in NOTCH2 and clinical features characteristic of Hajdu-Cheney syndrome is reported, with acroosteolysis of the distal phalanges of the feet and hands, generalized osteoporosis, musculoskeletal and craniofacial alterations, short stature, bowing of long bones, vertebral anomalies, genu recurvatum, hypertrichosis, joint and skin hyperlaxity, atopic dermatitis, megalocorneas, micrognathia and frequent respiratory infections, among others. Treatment is with bisphosphonates in the framework of bone density improvement and with focal vibration therapy for rehabilitation of the musculoskeletal system and gait improvement. The three generalities of this pathology-phenotypic variability, degenerative character and the presence of generalized osteoporosis and acroosteolysis of the distal phalanges-are seen in this case, whose diagnostic confirmation was made by genetic study.
ABSTRACT
Patients frequently experience a weight gain after organ transplantation. This increase in weight is the result of multiple factors, and is usually intensified by glucocorticoids and immunosuppressive drugs. It can also delay graft function and cause serious health problems. The objective of this study was to study the obesity as well as its causes and consequences in kidney transplant patients. The sample population consisted of 282 renal transplant patients, 170 men and 112 women, 18-74 years of age, who were monitored over a period of five years. For the purposes of our research, the patients were divided into two groups: (1) normal weight 18.5 ≤ BMI <25; (2) overweight 25 ≤ BMI ≤30. The association between BMI as an independent variable and graft survival was determined by means of a Cox regression analysis. Overweight patients were characterized by a higher comorbidity prevalence. In the Cox multivariate analysis, the initial BMI, evaluated as a continuous variable continued to be an independent predictor of delayed graft function and chronic nephropathy. This study evaluated the BMI as a continuous value instead of a categorical value. In conclusion, our results suggest that an increase in BMI without categorical variation can be an independent risk factor for graft loss. Consequently, obesity prevention for renal transplant patients should include dietary counseling and management, moderate physical activity, and steroid minimization.
