ABSTRACT
Background:
The devastating coronavirus disease of 2019 (COVID-2019) epidemic has been declared a public health emergency, resulting in a worldwide pandemic. The omicron variety is the most common epidemic mutant strain in the globe. Serum beta-2 microglobulin (ß2-MG) is associated with endothelial cell injury and has value in monitoring the progression of inflammation in infected individuals. Nonetheless, the potential functions of ß2-MG in omicron remain elusive.Methods:
To investigate the prognostic value of serum ß2-MG levels at diagnosis, we retrospectively analyzed a cohort of 240 people with omicron. Over the course of 65 days, all patients were monitored, and death was the primary outcome. Patients were allocated to two groups those with high and low ß2-MG levels. The Kaplan-Meier method was used to examine OS, and the log-rank test was used to compare them. Univariate and multivariate Cox hazard models were used to determine the prognostic significance.Results:
Our results revealed that ß2-MG was significantly elevated in omicron. ß2-MG levels in severe patients were higher than in mild-to-moderate patients, and the difference was statistically significant. Timely, interleukin-6 (IL-6) and interleukin-10 (IL-10) were observed to be significantly increased in individuals exhibiting elevated levels of ß2-MG. In addition, patients exhibiting elevated levels of ß2-MG demonstrated a statistically significant decrease in overall survival (OS, P < 0.0001). An elevated ß2-MG level (≥4.72 mg/l) was found to be an independent, adverse prognostic factor for OS in omicron patients, according to multivariate Cox proportional hazards regression analysis (P = 0.001).Conclusion:
Serum ß2-MG level at initial diagnosis was significantly correlated with omicron severity and prognosis. Thus, we propose that ß2-MG may be an independent poor additional prognostic factor in patients with omicron.Palabras clave
