L-citrulline to reduce complications in hospitalized young children with fever

Official title: A Randomised, Double-blind, Placebo-controlled Trial of L-Citrulline Oral Supplementation to Improve Short and Long-term Outcomes of Admitted Febrile Paediatric Patients With Biomarker-determined High-risk of Adverse Outcomes

Run by Barcelona Institute for Global Health · NCT06426147 · Data updated 2026-11-12

This trial will test whether giving L-citrulline versus placebo to hospitalized children aged 1 month to under 5 years who have a moderate-to-high bedside sTREM-1 risk result can reduce death and serious complications.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 1 month to under 5 years who are admitted with fever or suspected severe infection and whose bedside sTREM-1 result indicates moderate or high risk.

Probably not a fit

Children outside the age range, those classified as low risk by the sTREM-1 test, admitted for non-medical/social reasons, or with known contraindications to the supplement are unlikely to benefit from this intervention.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Children admitted with fever or suspected severe infection are first screened at the bedside with a rapid sTREM-1 point-of-care test to assign low, moderate, or high risk. Those aged 1 month to under 5 years with a moderate (yellow) or high (red) sTREM-1 result are randomly assigned 1:1 to receive L-citrulline or placebo in addition to standard care. Participants are followed during admission and by visits or phone at day 3, 5, 7, day 28 and month 6 to capture outcomes. The primary outcome is a composite adverse disease outcome within 28 days including death, new neurological problems, major kidney events, need for organ support, shock, coma, severe respiratory distress or readmission.

Why it matters

Potential benefit: If effective, L-citrulline could lower in-hospital deaths and serious complications for high-risk febrile children identified by the bedside sTREM-1 test.

How similar studies have gone: Bedside sTREM-1 measurements have prior supportive evidence as a prognostic marker, but using L-citrulline as an adjunctive treatment in this pediatric inpatient setting is novel and not yet proven.
