Introduction: Although contrast induced nephropathy (CIN) is a well-known complication of radiocontrast media administration among patients with underlying renal insufficiency, however the data about CIN among patients with normal renal function are few and it seems that CIN often remained under-diagnosed among these patients.
Objectives: The aim of present study was evaluation of CIN in diabetic and nondiabetic patients with normal renal function undergoing coronary angiography.
Patients and Methods: This cross-sectional and prospective study has conducted on patients with normal renal function candidate for diagnostic coronary angiography at Imam hospital, Ahvaz, Iran from October 2010 to February 2011. CIN defined as an increase in serum creatinine (sCr) >0.5 mg/dL after two days of contrast administration. A standardized questionnaire was used to collect demographics, clinical and laboratory data.
Results: A total of 254 patients (140 males and 114 Females with mean age of 56.6 ± 11.9 years) were included in the study. Of them, 60 patients (23.6%) had congestive heart failure (CHF) and 57 patients (22.4%) had diabetes mellitus (DM). The mean sCr levels before contrast administration in men and women were 1.05 ± 0.22 and 0.93 ± 0.17 mg/dL respectively. In overall CIN occurred in 27 patients (10.6%) with no difference between males and females (P = 0.386) and in patients with or without CHF (P = 0.766). There was a significant association between CIN and DM (P = 0.001) and mean volume of contrast administration (P = 0.001).
Conclusion: Although CIN is a common problem in patients with diabetic nephropathy undergoing coronary angiography, diabetic patients without diabetic nephropathy and also patients without DM who had normal renal function are also at risk of contrast nephropathy.
Coronary artery disease (CAD) is one of the leading causes of death and disability all around the world. Recent studies have revealed that aberrantly regulated long non-coding RNA (lncRNA) as one of the main classes of cellular transcript plays a key regulatory role in transcriptional and epigenetic pathways. Recent reports have demonstrated that circulating lncRNAs in the blood can be potential biomarkers for CAD.
HOTAIR
is one of the most cited lncRNAs with a critical role in the initiation and progression of the gene expression regulation. Recent research on the role of the
HOTAIR
in cardiovascular disease lays the basis for the development of new studies considering this lncRNA as a potential biomarker and therapeutic target in CAD. In this study, we aimed to compare the expression of
HOTAIR
lncRNA in the blood samples of patients with CAD and control samples. The expression level was examined by semi-quantitative reverse transcriptase polymerase chain reaction technique. Our data shows that expression of
HOTAIR
is up-regulated in blood samples of patients with CAD.
This research contains data which were obtained during the analysis of treated patients with aspirin who were referred to Imam Hospital (Imam H) of Ahvaz, Iran; and the effect of this type of treatment (Helicobacter pylori eradicate (HPE)) on reducing the incidence of gastrointestinal complications. Studies have shown that taking aspirin in patients with Helicobacter pylori infection is associated with a decreasing risk of gastrointestinal bleeding (O'connor et al., 2013) [1]. In this study, 165 patients with positive helicobacter pylori infection test were chosen among those who were referred to Imam H. In this paper, the effects of sex, smoking, renal failer, diabetes, age, blood pressure and aspirin consumption have been studied (Fletcher et al., 2010) [2]. After completion of the observations and records of patient's medical records, the obtained coded data were fed into EXCELL. Data analysis was performed, using SPSS 16.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
