Iron is a vital substrate for hemoglobin production and sufficient iron stores are necessary to achieve and maintain adequate levels of hemoglobin. Unfortunately, more than one third of patients with cyanotic heart disease are iron-deficient (1),(2). In 1990, West et al, have demonstrated that more
The study will investigate digoxin to inhibit the hypoxic response in congenital erythrocytosis due to germ line mutations that result in up-regulated hypoxia sensing. These forms of congenital erythrocytosis, characterized by augmented levels of hypoxia inducible factor (HIF)-1 and/or HIF-2, are
Background:
Within intestinal epithelial cells, some of the imported iron is incorporated into ferritin and other storage forms. A fraction of the iron taken up from the intestinal lumen passes through the cell, and is exported across the basolateral membrane to enter the body. Ferroportin, a metal
A clinical, prospective, randomized controlled trial to determine the effect of prescribing oxygen in a group of COPD patients with PaO2 ≥50 and ≤55 mmHg who do not have erythrocytosis or pulmonary hypertension on echocardiogram (which are considered manifestations of chronic hypoxia). It will be
The advanced chronic lung disease (PAD) is characterized by the development of several structural abnormalities, and pulmonary and systemic functional with low potential for reversibility, in spite of the treatment. It is defined DPA whole lung non-neoplastic chronic in its final phase. Most people
Study aim A: Red cell mass and hypoxia:
Various forms of altitude training have been used to increase in particular endurance performance of elite athletes. The most commonly used approaches is either to live and train at altitude (Live high - train high; LHTH) or to live at high altitude while
Background Long-term oxygen therapy (LTOT) is the only component of the management of chronic obstructive pulmonary disease (COPD) that improves survival in patients with severe daytime hypoxemia (defined as an arterial oxygen pressure [PaO2] measured in stable state <= 55 mmHg or in the range 56-59
The research is designed to determine the prevalence and risk factors of pulmonary hypertension (PHT) in children and adolescents with sickle cell disease (SCD), and to determine the role of the hypoxic response in its pathogenesis. In this regard, proliferative vascular responses mediated by (i)
