Chronic obstructive pulmonary disease (COPD) is the only major disease with increasing death rate. In COPD, progressive reduction in quality of life is closely related to the increasing limitation of airflow due to chronic bronchitis, cell hyperplasia, fibrosis, and irreversible lung damage. Signaling pathways involved in inflammatory processes in COPD ...

The clinical features of Alzheimer's disease (AD) overlap with a number of other dementias and conclusive diagnosis is only achieved at autopsy. Accurate in-life diagnosis requires finding biomarkers suitable for early diagnosis, as well as for discrimination from other types of dementia. Mounting evidence suggests that AD-dependent processes may also ...

Combined chelation treatment may be a better approach for transfusion-dependent thalassemia major patients with iron overload complications because of increased efficacy. Combination therapy with desferrioxamine and deferiprone has already been reported to improve survival dramatically by reversing cardiac dysfunction and other endocrine complications. Some patients have intolerance or inconvenience to ...

Congenital dyserythropoietic anaemias (CDAs) are heterogeneous, hereditary disorders hallmarked by ineffective erythropoiesis and tissue iron overload. Growth differentiation factor 15 (GDF15) was suggested to mediate iron overload in iron-loading anaemias, such as the thalassaemias and CDAI by suppressing hepcidin, the key regulator of iron absorption. Here, we show that serum ...

Nephrogenic systemic fibrosis (NSF) is a fibrotic disease that presents with a history of renal dysfunction. The differential diagnosis generally includes scleromyxedema, systemic sclerosis, and morphea. Especially, scleromyxedema can be extremely difficult to distinguish microscopically. Although the fibrocytes in NSF are often positive for CD34 and procollagen-I, this is not ...

The diagnostic criterion for beta thalassemia trait (BTT) is elevated Hb-A(2) levels. Iron deficiency anemia (IDA) reduces the synthesis of Hb-A(2), resulting in reduced Hb-A(2) levels, so patients with co-pathological conditions BTT with IDA, may have a normal level of Hb-A(2). Many socio-economic factors like unawareness, poor diagnostic facilities, and ...

Many patients in the internal medicine ward have anemia. The etiology for the anemia may be multifactorial and, in the setting of inflammatory process when the ferritin is increased, it is difficult to diagnose iron deficiency anemia. Soluble transferrin receptor (sTfR) had been suggested as an indicator for iron deficiency. ...

Hemodialysis patients with larger hemoglobin level fluctuations have higher mortality rates. We describe facility-level interpatient hemoglobin variability, its relation to patient mortality, and factors associated with facility-level hemoglobin variability or achieving hemoglobin levels of 10.5-12.0 g/dL. Facility-level hemoglobin variability may reflect within-patient hemoglobin variability and facility-level anemia-control practices. Prospective cohort ...

Inadequate hepcidin production leads to iron overload in nearly all types of hemochromatosis. We explored the acute response of hepcidin to iron challenge in 25 patients with HFE-hemochromatosis, in two with TFR2-hemochromatosis and in 13 controls. Sixteen patients (10 C282Y/C282Y homozygotes, 6 C282Y/H63D compound heterozygotes) had increased iron stores, while ...
