IL-1RA is naturally secreted by human hosts to limit the activity of IL-1 during hyperinflammation [22]. For cytokine profiling, the Mann-Whitney U test was applied to ascertain significant differences in immune mediator levels between patients experiencing different fever patterns. Patients were categorized as having prolonged fever (lasting >7 days), saddleback fever (defined as recurrent fever which lasts for <24 hours, after defervescence beyond day 7 of illness), or controls if their fever was 7 days.
