BACKGROUND Although there is a well-documented risk of acute renal failure (ARF) with the iodinated contrast agents, intravenous gadolinium-based contrast agents are considered non-nephrotoxic and have been widely used for magnetic resonance imaging (MRI). However, debate continues regarding the safety issue of gadolinium, especially in patients with kidney(More)
BACKGROUND Several recent studies reported that a high baseline serum C-reactive protein (CRP) is a powerful predictor of mortality in dialysis patients. However, the acute-phase response is intermittent and not a continuous feature in an individual patient. The aim of this prospective study was to determine whether serial analysis of serum CRP during(More)
Patients with chronic renal failure have an increased incidence of tuberculosis due to decreased cellular immunity. More than half of the tuberculosis infection in these patients presented with extrapulmonary involvement. Tuberculous peritonitis is an important problem in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Simultaneous(More)
BACKGROUND Thrombophilia has been implicated in the development of avascular necrosis (AVN) in various diseases. We aimed to search for the relation of both prothrombin gene G20210A mutation and factor V G1691A (factor V Leiden) mutation with AVN among kidney transplant recipients. METHODS Nineteen patients with AVN and 38 control patients without AVN(More)
Certain viral and bacterial infections may contribute to the initiation and progression of atherosclerosis. The aim of this study is to determine whether Helicobacter pylori (HP) seropositivity contributes to conventional atherosclerosis risk factors in the development of an early sign of atherosclerosis: intima-media thickness (IMT) of the carotid artery.(More)
We report a case of spontaneous bacterial peritonitis caused by Klebsiella pneumoniae in a 34-year-old male recipient shortly after kidney transplantation. On posttransplant day 10, the patient started complaining of severe abdominal pain and nausea. Body temperature was 38.4 degrees C. The abdomen was diffusely tender with rigidity and rebound. Laboratory(More)
Idiopathic retroperitoneal fibrosis (RF) is a histologically benign, nonspecific inflammatory process of the fibroadipose tissue in the retroperitoneum with an unknown etiology. It may be complicated due to encasement and obstruction of the retroperitoneal structures. Tamoxifen has been known to be an effective agent in regression of desmoid tumors which(More)
OBJECTIVE To study the effect of antihypertensive drugs in essential hypertension and in the central retinal, posterior ciliary, and ophthalmic arteries by using Doppler sonography. METHODS Thirty patients with essential hypertension and 32 control subjects were enrolled in the study. The pulsatility and resistive indices were evaluated in the central(More)
