Hospitalized sufferers with COVID-19 and irregular sodium ranges within the blood have an elevated danger of experiencing respiratory failure or dying, in accordance with a examine revealed within the Endocrine Society’s Journal of Scientific Endocrinology & Metabolism.
“This examine exhibits for the primary time that sufferers presenting on the hospital with COVID-19 and low sodium are twice as prone to want intubation or different technique of superior respiration help as these with regular sodium,” stated lead investigator Ploutarchos Tzoulis, M.D., Ph.D., M.Sc., Honorary Affiliate Professor in Endocrinology at College Faculty London (UCL) Medical Faculty in London, U.Okay.
Moreover, the researchers discovered that sufferers who develop excessive sodium ranges through the hospital keep have been thrice extra prone to die than those that have regular sodium ranges all through hospitalization.
“Sodium measurements can inform medical doctors about which COVID-19 sufferers are at excessive danger of degradation and demise,” Tzoulis stated. “Sodium ranges can information resolution making about whether or not a COVID-19 affected person wants hospital admission or monitoring within the intensive care unit.”
Sodium is routinely measured as a part of bloodwork achieved for all sufferers coming to the hospital, and its measurement is cheap, Tzoulis famous. Sodium is a necessary mineral and helps regulate fluid quantity within the physique and blood stress.
The examine was carried out in 488 adults with COVID-19 admitted to 2 London hospitals, UCL Hospital and Whittington Hospital, over an eight-week interval final 12 months. The 277 males and 211 ladies had a median age of 68 years. That they had a median hospital keep of eight days.
Practically 32 p.c of COVID-19 sufferers with low sodium ranges at admission wanted a respiration tube and ventilator or oxygen by means of a face masks in contrast with solely 17.5 p.c of sufferers whose sodium values have been regular, the investigators reported. Not like extra sodium within the blood, low sodium ranges had no affiliation with an elevated danger of dying within the hospital, Tzoulis stated.
Amongst sufferers with excessive sodium ranges at any time throughout their hospital keep, almost 56 p.c died versus about 21 p.c of sufferers whose sodium remained regular, the information confirmed.
Docs often deal with excessive sodium ranges with intravenous fluids, and low sodium might require intravenous fluids, fluid restriction or medicines. Nevertheless, each circumstances are sometimes underestimated and undertreated, Tzoulis stated.
Fluid losses attributable to diarrhea, vomiting, sweating, and never ingesting sufficient water can result in excessive sodium ranges. Subsequently, Tzoulis burdened the significance of avoiding dehydration throughout a hospital admission for COVID-19.

The manuscript, “Dysnatremia is a Predictor for Morbidity and Mortality in Hospitalized Sufferers with COVID-19,” was revealed on-line, forward of print.
The analysis additionally can be offered at ENDO 2021, the Endocrine Society’s annual assembly, which runs from March 20-23.
