Hypoxia and hypercarbia of chronic lung disease: minimal effects on anterior pituitary function

Southern Medical Journal
W A Banks, J A Cooper

Abstract

Previous studies have suggested that the hypoxia and/or hypercapnia associated with chronic lung diseases may lead to pituitary and gonadal dysfunction, with destruction of the sella turcica. It is unclear, however, whether these abnormalities were due to lung disease or to confounding factors. We studied the relationships between hormonal levels (triiodothyronine, thyroxine, T3 resin uptake, thyrotropin, prolactin, cortisol, and testosterone) and PaO2, PaCO2, pH, and alveolar-arterial gradient in 25 patients with chronic lung disease. These patients were highly homogeneous for diagnosis, age, sex, ambulatory status, lack of other illnesses, and minimal use of medications unrelated to lung disease, but did have various degrees of hypoxia and hypercarbia at the time of study. We found no relationship between hormonal levels and lung function, or evidence of major pituitary involvement on lateral roentgenograms of the skull, CT of the sella turcica, or stimulation of the pituitary. An inverse correlation did occur between serum levels of thyroxine and the daily dose of oral prednisone. We conclude that most of the endocrine dysfunction ascribed to chronic lung diseases is probably due to factors other than hypoxia or hypercarbia.

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
