Urinary levels of endothelin-1 in type 2 diabetes mellitus patients: a non-defined marker of early renal damage

چکیده
Antecedentes/Objetivo: La excreción de endotelina-1 urinaria (UET-1) es mayor en pacientes con enfermedad renal de cualquier etiología, comparados con sujetos normales, por lo que ésta podría servir potencialmente como un marcador de daño renal. Metodología: Comparamos la excreción de UET-1 en 67 pacientes con diabetes tipo 2 (DM2) con y sin hipertensión (HTA), y en presencia o ausencia de microalbuminuria (MA). Estudiamos 14 sujetos sanos como grupo control. La microalbúmina y la endotelina fueron medidas en orina de 24 horas. La diferencia entre los grupos fue determinada mediante prueba ANOVA. Utilizamos una prueba de correlación múltiple para buscar asociación entre la UET-1 y el tiempo de evolución, control metabólico y daño renal. Resultados: La excreción de UET-1 fue mayor en el grupo de diabetes sin MA con respecto al grupo de diabetes con MA (p < 0.04). Se encontró diferencia significativa entre la excreción de UET-1 del grupo control y el grupo de diabetes sin HTA. Conclusiones: En nuestro estudio, la excreción de UET-1 tiende a ser mayor en pacientes diabéticos sin HTA al compararlos con pacientes diabéticos con hipertensión. Consideramos que es necesario continuar estudiando la participación de la UET-1 en la patología renal con modelos que además de evaluar la función glomerular incluyan otros sitios como el túbulo proximal.

Serum Cystatin C and Tubular Urinary Enzymes as Biomarkers of Renal Dysfunction in Type 2 Diabetes Mellitus
Renal tubulointerstitium plays an important role in the development and progression of diabetic nephropathy. The aim of this study was to assess serum cystatin C and 2 renal tubular enzymes, neutrophil gelatinase associated lipocalin (NGAL) and N-acetyl-beta-D-glucosaminidase (NAG), as screening markers for early renal dysfunction in patients with type 2 diabetes mellitus (T2DM). ROC curve anal...

OBJECTIVE To evaluate the clinical usefulness of urinary N-acetyl-beta-D-glucosaminidase (NAG) excretion for the detection of early tubular damage in type 2 diabetes mellitus (T2DM). SUBJECTS AND METHODS Thirty six patients with T2DM were divided into two groups based on urinary albumin to creatinine ratio (ACR): normoalbuminuria (ACR <30 mg/g; n=19) and microalbuminuria (ACR =30-300 mg/g; n=...
متن کاملUrinary endothelin-1 as a marker of renal damage in sickle cell disease.
BACKGROUND Sickle cell disease (SCD) affects the kidney by acute mechanisms as well as by insidious renal medullary/papillary necrosis, resulting in tubular defects, which increase the risk of dehydration and subsequent sickle crisis. Hypoxia has been reported to stimulate endothelin-1 (ET-1) synthesis by endothelial cells and also in the renal tubule. METHODS This case-control study measured...
