About the topic:

Oxygen is the fundamental critical element for life on planet Earth. Unavailability of inspired oxygen for more than 5 minutes can lead to death. Generalized hypoxemia can result from hypobaric hypoxia present at high altitude, but it can also result from pulmonary diseases. Localized tissue hypoxemia can arise from vascular obstruction of circulation. The COVID-19 pandemic has shown that extensive lung affectation can be associated with "silent hypoxemia". This condition is not entirely understood, although several papers have addressed the subject. Hypoxemia levels previously thought intolerable at sea level have changed the concepts of oxygen transport physiology. High altitude physiology includes “silent hypoxemia” as humans live under low levels of oxygen pressure known as chronic hypoxia. The Oxygen Transport Triad, described at high altitude, is based on three systems: the pneumo-dynamic pump (air vacuum ventilation of the lungs), the hemo-dynamic pump (blood compression through valve mechanism of the heart), and hemoglobin (oxygen transport molecule in red blood cells). These three pillars of oxygen transport in mammals respond with variations in acute and chronic hypobaric hypoxia. The extensive lung compromise in the COVID aggression, which we have defined as pneumolysis (lung destruction), gives rise to altered oxygen transport and resulting extreme hypoxemia that can be lethal. In COVID, studies are required to show the different hypoxic etiopathogenesis conditions, including shunts, uneven ventilation/ perfusion, diffusion alterations, and hypoventilation. This involves not only alveolar-capillary affectation but also respiratory center alterations. Furthermore, high altitude decreased COVID incidence, and lethality need further studies.

This special issue welcomes the submission of original research, short communications, and review manuscripts within oxygen transport physiology and COVID at high altitude, moving science towards new horizons.

Chest CT Scan Features of COVID-19 in a Hospitalized High-Altitude Population

Received: 30 November 2022;  Published: 12 April 2024;  doi: 10.21926/obm.genet.2402226


There is a lack of knowledge regarding the type of lung compromise in high-altitude residents with COVID-19. This study aims to evaluate the lung compromise in chest CT scans of high-altitude dwellers hospitalized with COVID-19. Retrospective study that took place in "Daniel Alcides Carrión" Regional Hospital, located 3,250 meters [...]

An Evidence of Drug Repurposing for COVID-19 Pandemic Based on In silico Investigation from Phenolic Derivatives of Silybum Marianum Against SARS-Cov-2 Proteins

Received: 11 January 2023;  Published: 04 July 2023;  doi: 10.21926/obm.genet.2303186


The outbreak of coronavirus disease-2019 (COVID-19) had a striking impact on the worldwide healthcare system within a very short period. The availability of a large number of clinical data on SARS-CoV-2, conventional precautionary majors, and treatment strategies with the existing therapeutic antiviral drug molecules also fails [...]

High-Altitude Pulmonary Edema in the Context of COVID-19

Received: 18 July 2022;  Published: 09 September 2022;  doi: 10.21926/obm.genet.2203163


High-altitude pulmonary edema (HAPE) and COVID-19 pneumonia are different diseases, but HAPE-susceptible individuals (whose susceptibility often has a genetic basis) can also suffer from severe COVID-19. We hypothesized that certain pathogenic mechanisms might overlap if such a coincidence occurs, since these patients could react [...]
