ABSTRACT
Resumen Las infecciones en personas con enfermedad renal crónica son una causa importante de morbimortalidad. Los pacientes renales presentan factores de riesgo específicos para la adquisición de infecciones, que además suelen ser más graves, de progresión más rápida y de resolución más lenta que en sujetos sanos. La infección del tracto urinario en esta población es a menudo complicada debido a la presencia de diabetes, microorganismos multirresistentes, anomalías anatómicas o funcionales del tracto urinario, alteraciones metabólicas y el uso frecuente de sonda vesical. Las infecciones urinarias ocasionan una de las tasas más altas de hospitalización en diálisis y son muy prevalentes en el trasplante renal. Este trabajo tiene como objetivo revisar la literatura publicada sobre la etiología, el diagnóstico microbiológico y el tratamiento de las infecciones del tracto urinario en pacientes con enfermedad renal crónica.
Abstract Infections in chronic kidney disease patients are a major cause of morbidity and mortality. Renal patients have specific risk factors for acquiring infections, which also tend to be more severe and have a more rapid progression and slower resolution than in the healthy individuals. Urinary tract infection in renal patients is often complicated due to the presence of diabetes, multiresistant microorganisms, anatomic or functional abnormalities of the urinary tract, metabolic disturbances and the frequent use of urinary catheters. It causes one of the highest rates of hospitalization among dialysis patients and is highly prevalent in kidney transplantation. The aim of this work is to review the etiology, microbiological diagnosis and treatment of urinary tract infections in chronic kidney disease patients.

OBJECTIVES: Coenzyme Q(10) (CoQ(10)) is an essential electron carrier in the mitochondrial respiratory chain and a strong antioxidant. Signs associated with skin alteration and mitochondrial dysfunction have been observed in patients with fibromyalgia (FM). The aim of this study was to analyze CoQ(10) levels, mitochondrial dysfunction, and oxidative stress in plasma, blood mononuclear cells, and skin biopsies from FM patients. METHODS: We studied CoQ(10) level by HPLC in plasma, blood mononuclear cells, and skin obtained from patients with FM and healthy control subjects. Oxidative stress markers and mitochondrial respiratory chain enzyme activities were analysed in both plasma, blood mononuclear cells, and skin biopsies from FM patients. RESULTS: Oxidative stress, mitochondrial dysfunction, and CoQ(10) deficiency have been observed in blood mononuclear cells and skin biopsies. CONCLUSIONS: In our patients, mitochondrial dysfunction and CoQ(10) deficiency are present in several tissues. These results may contribute to the understanding of the pathophysiology of FM, and, moreover, CoQ(10) deficiency could represent a good marker for the diagnosis of FM.
