Haematologic adaptation in patients with chronic bronchitis and pulmonary insufficiency

Abstract

The relationship between respiratory insufficiency, expressed by gas tensions in blood and bone marrow, and haematologic adaptation has been studied in 82 men with chronic bronchitis and persistent breathlessness for at least one year. For the group as a whole and for various subgroups, a linear correlation was demonstrated between arterial hypoxia and Hb concentration, haematocrit, blood volume, Hb mass and erythrocyte volume, respectively. The increase in Hb concentration compensated for the fall in arterial oxygen saturation. Only for one subgroup, with a pH difference between arterial and venous blood larger than or equal to 0.08, was no correlation found between the degree of hypoxia and Hb concentration. The haematologic parameters correlated significantly better with arterial oxygen tensions than with oxygen tensions in the bone marrow. There was no indication that decreased oxygen supply to the bone marrow led to the increased erythrocyte and Hb production in patients with arterial hypoxia caused by chronic bronchitis.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
