Therapeutic plasma exchange (TPE) potentially mitigates the harmful effects of such cytokines.

This group was compared with COVID\u201019 patients who received standard therapy without TPE. The following outcomes were analyzed: changes in laboratory parameters, length of hospital stay (LOS), days on mechanical ventilation, mortality at days 14 and overall mortality.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 95 patients were included, among whom 47% (n\u00a0=\u00a045) received TPE.

However, they were more likely to be associated with longer LOS (23 vs 14\u2009days; <jats:italic>P<\/jats:italic>\u00a0=\u2009.002) and longer days on ventilatory support (14 vs 8\u2009days; <jats:italic>P<\/jats:italic>\u00a0&lt;\u2009.001). Despite marginal mortality benefit at 14\u2010days (7.9% vs 24%; <jats:italic>P<\/jats:italic>\u00a0=\u2009.071), there was no significant differences in overall mortality (21% vs 31%;
