NCT ID NCT06573671

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This observational study looks at a newly identified lung condition called histiocytosis in people who inject drugs. Researchers will study 30 patients to understand symptoms, diagnosis, and outcomes. They will also test new ways to detect a substance called polyvinylpyrrolidone (PVP) that may cause the condition. The goal is to improve diagnosis and distinguish it from other similar diseases.
