Hospital study tracks deadly fungus and a possible predictor of patient outcomes
NCT ID NCT07621263
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study at Hospital H+ Querétaro looked at 150 patients with suspected or confirmed invasive aspergillosis, a serious fungal infection. Researchers measured a substance called galactomannan in lung fluid samples to see if higher levels were linked to worse outcomes like death or longer hospital stays. The study also tracked how often the infection occurred over different seasons and years. The goal was to better understand the infection and see if this biomarker can help predict patient outcomes.
