Using infection‑related hospitalizations after heart transplantati ... Full text Link to item CiteReduced lung fluid club cell secretory protein informs chronic lung allograft dysfunction risk.
Journal Article Eur Respir J · April 2026 BACKGROUND: Lung transplant recipients with lower club cell secretory protein (CCSP) levels in bronchoalveolar lavage fluid (BALF) early post-transplantation are at increased risk for chronic lung allograft dysfunction (CLAD). For CLAD risk stratification, ...
