Background: Atrial fibrillation (AF) is the most common arrhythmia in patients with β-thalassemia major (β-TM) due to cardiac iron overload. AF may be predicted by changes in P wave parameters. The aim of this study was to evaluate the correlation between P-wave parameters and atrial markers with mean serum ferritin levels measured yearly. Methods: Fifty patients with β-TM and 50 healthy subje...

ABSTRACT BACKGROUND In beta thalassaemia major multiple blood transfusions, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body. Iron overload impairs the immune system, placing patients at greater risk of infection and illness. Iron overload can be determined by serum ferritin measurement. OBJECTIVE The aim of the present study is to...

BACKGROUND Ferritin is a high molecular weight protein which reflects body iron stores, but may also rise in the case of an acute phase response. Recently, ferritin has been identified as a predictive factor in the development and progression of atherosclerosis. This is the first report on serum ferritin levels in patients with proteinuria. METHODS We have analysed the data of 142 male patien...

Urinary ferritin levels were measured by a "2-site" immunoradiometric assay in normal volunteers and in patients with various hematologic disorders. The mean urinary ferritin concentration in normal subjects averaged 2.2 microgram/liter, only 3% of the serum ferritin level. Elevated urinary ferritin levels averaging 45 microgram/liter were observed in patients with hematologic malignancies, but...

1. The properties of ferritin in serum have been compared with those of ferritin from a number of tissues including blood cells. On anion-exchange chromatography with DEAE-Sephadex, the behaviour of human heart ferritin is different from that of liver, kidney or spleen ferritin. Reticulocyte ferritin appears to have similar characteristics to heart ferritin. 2. Serum ferritin from normal subjec...

BACKGROUND AND PURPOSE Several studies have provided evidence for a relationship between body iron load and cardiovascular disease. We analyzed the association of serum ferritin levels with carotid atherosclerosis. METHODS We assessed intima-media thickness and plaque prevalence in the carotid arteries by high-resolution ultrasound among 2443 participants (1200 women; age, 45 to 79 years) in ...

background: increased estimated body iron stores have been recently suggested to be associated with increased risk of acute myocardial infarction (ami); however the question of whether serum ferritin level as an indicator for estimating body iron is an independent risk factor for cardiac events is still questioned. in the present study, we assessed whether serum ferritin was associated with the...

BACKGROUND Recent studies revealed elevated serum ferritin levels predict new-onset type 2 diabetes. Further studies proved ferritin to be an important and independent predictor of the development of diabetes. The link between hyperglycemia, enhanced free radical activity (oxidative stress) and serum iron and its stores (serum ferritin levels) levels is not clear. OBJECTIVES The present study...
