Abstract
- This study described a soluble mediator storm in acute Yellow Fever/YF infection along the kinetics timeline towards convalescent disease. The analyses of the YF Viral RNAnemia, chemokines, cytokines, and growth factors were performed in YF patients at acute/(D1–15) and convalescent/(D16–315) phases. Patients with acute YF infection displayed a trimodal viremia profile spreading along D3, D6, and D8–14. A massive storm of mediators was observed in acute YF. Higher levels of mediators were observed in YF with higher morbidity scores, patients under intensive care, and those progressing to death than in YF patients who progress to late-relapsing hepatitis/L-Hep. A unimodal peak of biomarkers around D4–6 with a progressive decrease towards D181–315 was observed in non-L-Hep patients, while a bimodal pattern with a second peak around D61–90 was associated with L-Hep. This study provided a comprehensive landscape of evidence that distinct immune responses drive pathogenesis, disease progression, and L-Hep in YF patients. • Patients with acute YF infection displayed a trimodal viremia profile. • A massive storm of soluble mediators was observed in acute yellow fever. • Discharge was associated with a compact/network, and death to a disrupted network. • In acute disease, high levels of IFN-γ prevented L-Hep. • In convalescence disease, high levels of CXCL8 identified L-Hep.
