Overview
Brief Summary
Evaluation of the effectiveness and safety of transbronchoscopic local precision infusion of amphotericin B + transoral nebulized inhalation of amphotericin B + transbronchoscopic interventional debridement + liposomal amphotericin B + posaconazole or Isavuconazole multimodal treatment of pulmonary mucormycosis
Detailed Description
Key rationale for the treatment of mucormycosis is early surgical intervention, including local debridement and removal of infected tissues or organs if possible. Systemic antifungal therapy is also necessary for mucormycosis, including amphotericin B liposomes and deoxycholates, Isavuconazole, posaconazole, and so on. Antifungal drug therapy has a mortality rate of up to 40%, which can be reduced to 23% when combined with surgical treatment. However, some patients who are unable to tolerate surgical procedures on the chest when in bad condition, especially patients with hematological malignancies undergoing hematopoietic stem cell transplantation, are susceptible to multiple mucormycosis of the lungs, and the mortality rate of untreated systemically disseminated mucormycosis infections is high at 80%. Isavuconazole, so we aim to explore the multimodal treatment of liposomal amphotericin B + posaconazole or esaconazole + transbronchoscopic localized precise instillation of amphotericin B + oral nebulized inhalation of amphotericin B + transbronchoscopic interventional debridement to alleviate the pulmonary mucormycosis in chest imaging and reduce the mortality rate of patients with mucormycosis infection.
