"Cyanotic nephropathy"

Nattaphorn Hongsawong, Prapimdaw Khamdee, Suchaya Silvilairat, Wattana Chartapisak
BACKGROUND: Cyanotic nephropathy (CN), seen in 30-50% of patients with congenital cyanotic heart disease (CCHD), affects both tubular and glomerular function, resulting in proteinuria and azotemia. Microalbuminuria is an early marker for glomerular damage and an independent predictor of progressive renal disease. METHODS: A cross-sectional study was conducted. A total of 116 patients aged 1 month to 15 years with CCHD at Chiang Mai University Hospital between 2015 and 2016 were assessed and 94 patients were enrolled...

OBJECTIVE: Nephropathy is a known complication in cyanotic congenital heart disease (CCHD). This study was undertaken for an objective analysis of histopathological changes of cyanotic nephropathy at autopsy. DESIGN: Retrospective case records studied. SETTING: Tertiary care teaching hospital affiliated to medical college in Mumbai, India. PATIENTS AND METHODS: The renal histopathological findings of 50 consecutive autopsies in patients with CCHD were compared with 25 age-matched controls...

Patients over 10 years of age with cyanotic congenital heart disease (CCHD) risk developing significant glomerular proteinuria, a condition called cyanotic nephropathy. Even though the pathogenesis of glomerulopathy associated with CCHD is still unclear, a potential mechanism is hyperviscosity-induced decrease in peritubular capillary blood flow leading to an increase in glomerular capillary pressure, in turn resulting in proteinuria. Although angiotensin-converting enzyme (ACE) inhibitors have been traditionally used in the treatment of these patients with cyanotic nephropathy, they may, however, not be well tolerated...

Cyanotic congenital heart disease (CCHD) is a life-threatening cardiac defect that requires palliative or corrective surgery in early life. Major advances in medical and surgical management have resulted in the survival of CCHD patients to adulthood with or without corrective surgery, though some are at risk of development of end-stage renal disease (ESRD) due to cyanotic nephropathy (CN). There is little or no information on the initiation and maintenance of hemodialysis (HD) in such patients. We present here a case of a 44-year-old man with complete transposition of the great arteries and CN-related ESRD...

Cyanotic nephropathy (CN) is often accompanied by congenital cyanotic heart diseases (CCHD). The purpose of this study was to clarify the risk factors and the mechanisms of involved in the development and progression of CN. Thirty patients with CCHD were examined. We analyzed the risk factors for the development of CN on the basis of the clinical and laboratory findings. We also examined ten renal biopsy specimens obtained from patients with CN. Patients with CN showed significantly higher hematocrit levels than those without CN (P=0...

BACKGROUND: Chronic cyanosis with its associated rheologic changes is a known risk factor for glomerular nephropathy. Therefore, contrast-induced nephrotoxicity should be an important consideration for angiographers comparable to diabetics. On the other hand, progressions in diagnostic and interventional techniques have led to expanded indications and a more widespread use of x-ray contrast agents. The aim of this study was to investigate the risk of contrast-induced nephropathy in the small group of patients with cyanotic heart disease prior to surgical repair...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign
