Finding biomarkers and causes of dangerous antibiotic reactions

An integrative approach to identify biomarkers and investigate mechanisms of adverse drug reactions

NIH-funded research Children's Mercy Hosp (Kansas City, Mo) · NIH-11327250

This project aims to find biological signs that show who is at risk for severe, life-threatening reactions to the common antibiotic trimethoprim-sulfamethoxazole (TMP-SMX).

What this research studies

From a patient's view, researchers will focus on severe, unpredictable reactions to the commonly used antibiotic TMP-SMX and look for biological markers that signal risk. They will combine genetic testing including HLA typing, chemical analyses of drug metabolites and protein adducts, and immune-cell experiments using blood and tissue samples. The team will build an integrated platform linking patient genetics, drug chemistry, and immune activation to pinpoint mechanisms and possible predictive markers. The work uses patient-derived samples and laboratory assays to better understand how drug metabolites might trigger immune responses that cause injury.

Who could benefit from this research

Good fit: Ideal candidates are people who have had severe or unexplained adverse reactions to TMP-SMX or healthy volunteers willing to provide blood or tissue samples for comparison.

Not a fit: People who have never taken TMP-SMX or whose reactions are clearly due to non-immune causes are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could enable tests that predict who is likely to have dangerous antibiotic reactions and help clinicians avoid harmful drugs.

How similar studies have performed: Previous studies have linked specific HLA genes to some drug reactions, but combining metabolite chemistry with immune assays to find predictive biomarkers is relatively novel.
