Insights

Higher serum hyaluronan (HA) levels indicate a greater risk of severe coronavirus disease 2019 (COVID-19). Measuring HA early can help predict disease severity in patients.

Area of Science:

  • Biochemistry
  • Immunology
  • Infectious Diseases

Background:

  • Hyaluronan (HA), a glycosaminoglycan, plays a role in inflammation and tissue repair.
  • Its role in the prognosis of coronavirus disease 2019 (COVID-19) remains to be fully elucidated.

Purpose of the Study:

  • To investigate the association between serum hyaluronan (HA) levels and the prognosis of COVID-19.
  • To determine if HA can serve as a predictive biomarker for COVID-19 severity.

Main Methods:

  • Serum HA levels were measured in 497 hospitalized COVID-19 patients.
  • Patients were categorized into mild (n=344) and severe (n=153) infection groups.
  • Correlations between HA, lymphocyte count, CRP, ferritin, IL-6, and D-dimer with COVID-19 prognosis were assessed.

Main Results:

  • Severe COVID-19 patients exhibited significantly higher mean serum HA levels (850.6 ng/mL) compared to mild cases (204.4 ng/mL).
  • An HA level threshold of ≥607.8 ng/mL predicted severe COVID-19 with 62.3% sensitivity and 88.6% specificity.
  • Multivariate analysis confirmed serum HA as a significant predictor of disease severity (OR=60.56).

Conclusions:

  • Elevated serum HA concentrations are strongly associated with severe COVID-19.
  • Early assessment of serum HA levels may effectively predict COVID-19 disease severity.
  • HA could be a valuable biomarker for risk stratification in COVID-19 patients.
