Testing the effectiveness of intravenous immunoglobulin for severe hemorrhagic fever with renal syndrome

Efficacy of Intravenous Immunoglobulin in Patients With Hemorrhagic Fever With Renal Syndrome: a Multicenter, Prospective, Randomized Controlled Study

PHASE4 · Tongji Hospital · NCT06009042

This study is testing if different doses of a treatment called intravenous immunoglobulin can help people with severe hemorrhagic fever with renal syndrome get better faster and reduce their hospital stay.

What this trial studies

This multicenter, prospective, randomized controlled study aims to evaluate the efficacy of different doses of intravenous immunoglobulin (IVIG) in treating patients with severe hemorrhagic fever with renal syndrome (HFRS). Approximately 100 hospitalized patients diagnosed with severe HFRS will be randomly assigned to receive either 10g/d or 20g/d of IVIG for six days, alongside routine supportive treatments. The study will collect various clinical and laboratory data to assess treatment outcomes, including transformation rates, mortality rates, and length of hospital stay.

Who should consider this trial

Good fit: Ideal candidates for this study are hospitalized adults aged 18 and older diagnosed with severe or critically ill HFRS within five days of symptom onset.

Not a fit: Patients with mild HFRS or those who do not meet the specific laboratory criteria for severe illness may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients suffering from severe HFRS.

How similar studies have performed: While there have been studies on IVIG for various conditions, this specific approach for severe HFRS is novel and has not been extensively tested.
