Invasive mold diseases (IMD) carry extremely high mortality rates in liver transplant recipients (aspergillosis prevalence \~1.8%, mortality 60%-90%; mucormycosis prevalence \~2%, mortality 38%-95%). Guidelines emphasize early antifungal therapy: liposomal amphotericin B (L-AmB) is the first-line choice in liver insufficiency; voriconazole remains the gold standard for aspergillosis (but ineffective against mucormycosis), yet its use is limited by significant drug-drug interactions-requiring a 50%-60% dose reduction of calcineurin inhibitors and contraindicated with sirolimus-thereby increasing the risk of graft rejection. Currently, no head-to-head clinical trials compare voriconazole and L-AmB in liver transplant recipients with IMD. Therefore, a prospective real-world study is planned to generate robust data to support updates to international or Chinese guidelines.
