Over the years, several reports have demonstrated involvement of the nervous system in beta-thalassemia patients. Neurological complications have been attributed to various factors such as chronic hypoxia, bone marrow expansion, iron overload, and desferrioxamine neurotoxicity. In most cases, neurological involvement does not initially present with relevant signs or symptoms (i.e., ...

Oral deferiprone (L1) appears to be promising in the treatment of beta-thalassemia major (TM) patients. T2* magnetic resonance imaging (MRI) with a single measurement in the mid-ventricular septum was validated as a quantitative evaluation of myocardial iron overload. Previous studies suggested a marked heterogeneity of iron distribution in the myocardium. ...

BACKGROUND: Anemia commonly complicates inflammatory bowel disease (IBD). In patients with chronic renal failure, the treatment of anemia with iron+/-erythropoietin improves both quality of life (QOL) and cognitive function (CF). The same drugs are effective in treating severe anemia in IBD, but there is no evidence to direct the treatment ...

Hypoparathyroidism is thought to be a rare consequence of iron overload seen in beta-thalassemic transfused patients. This study was conducted to determine the prevalence of hypoparathyroidism in a large number of beta-thalassemic patients, and its potential correlation with the presence of other endocrinopathies caused by iron overload. Serum and urine ...

Chronic red blood cell transfusion support in patients with myelodysplastic syndromes (MDS) is often necessary but may cause hemosiderosis and its consequences. The pathophysiologic effects of iron overload relate to increased non-transferrin bound iron generating toxic oxygen free radicals. Studies in patients with MDS and thalassemia major have shown adverse ...

Current guidelines give evidence-based advice on how best to manage anaemia in patients with renal disease, but these guidelines do not consider individual patient needs, so tailoring anaemia management to each patient still remains a challenge for the treating physician. Two case studies are described that illustrate some of the ...

Maple syrup urine disease (MSUD) is caused by a deficiency in the branched-chain alpha-ketoacid dehydrogenase complex. Accumulations of branched-chain amino acids (BCAAs) and branched-chain alpha-ketoacids (BCKAs) in patients with MSUD induce ketoacidosis, neurological disorders, and developmental disturbance. BCAAs and BCKAs influence on the nervous system can be estimated by analyzing ...

Over the last few years, increased evidence has supported the role of iron dysregulation in the pathogenesis of multiple sclerosis (MS), as iron is essential for myelin formation and oxidative phosphorylation. We studied indices of iron metabolism, such as serum iron, ferritin, transferrin and soluble transferrin receptor (sTFR) levels in ...

AIM: Iron deficiency anaemia is a frequent finding seen in coeliac disease, which can be diagnosed alone or with other findings. In this study, our aim was to determine the prevalence of coeliac disease in children with iron deficiency anaemia without significant gastrointestinal symptoms. METHODS: There were 135 children with ...

With the introduction of "hypertransfusion" regimens the extent of disease- and therapy-related hemosiderosis has become the survival limiting factor for patients with beta-thalassemia major as iron transferred with transfusions cannot be excreted by physiological means. Subsequent introduction of deferoxamine therapy for iron elimination and prophylaxis of hemosiderosis has improved prognosis ...

BACKGROUND: Albumin is a potent antioxidant as it chelates transitional metals and contains antioxidants like thiol and bilirubin. In neprotic syndrome, the defining parameter is proteinuria with hypoalbuminemia. Therefore albuminuria in nephrotic syndrome may increase toxic transitional metal ions and also can cause loss of albumin associated antioxidants causing oxidative ...

Iron overload is not uncommon in sickle cell disease (SCD) and requires regular chelation therapy in several instances. The present study evaluates the effect of deferiprone in 15 adult patients with SCD (ten beta(s)/beta(0)thalassemia and five beta(s)/beta(s)) and iron overload. Deferiprone was given at a dose of 75 mg/kg daily ...

At age of 3.2 years routine blood analysis showed the presence of a beta-thalassemic trait with unexpected high level of serum iron and high transferrin saturation. Hematological follow-up confirmed the moderate degree of anemia and persisting high levels of iron indices throughout the years with a progressive increase of serum ...
Jambrik Zoltán - - 2005
BACKGROUND: Patients with beta-thalassemia major often present with severe anemia and must undergo continuous transfusion therapy, consequently developing iron overload leading to hemochromatosis. Because of these the iron deposits and/or secondary structural changes, patients develop an increase in myocardial integrated backscatter (IB). AIM: To investigate the prognostic value of analyzing ...

It is known that anaemia in haemodialysis patients could contribute to haemostasis impairment. However, the precise relation between the degree of anaemia and the degree of haemostasis impairment is not known, nor the optimal level of hematocrit above which anaemia no longer disturbs haemostasis. Our study addresses these clinically relevant ...

BACKGROUND: We previously showed that the content of reticulocyte hemoglobin (CHr) is a reliable measure of iron status in chronic dialysis patients with erythrocytopoiesis. The CHr was significantly correlated with conventional parameters of iron deficiency in dialysis patients. We attempted to utilize the measurement of CHr levels to monitor iron ...
