Clinical characteristics and outcomes of invasive pulmonary aspergillosis in renal transplant recipients: A single-center experience
Objective
This study aimed to explore the clinical features, early diagnostic methods, and therapeutic approaches for invasive pulmonary aspergillosis (IPA) in patients after renal transplantation (RT).
Methods
We retrospectively examined 22 patients who were diagnosed with IPA post-RT and treated at our institution between 2005 and 2024.
Results
Patients had an average age of 46.4 ± 9.4 years, with a predominance of men (72.7 %). The incidence of IPA after RT was 1.29 %. The median time of IPA onset after transplantation was 12 months. Fever was the predominant symptom (72.7 %), followed by cough and expectoration (31.8 %) and hemoptysis (13.6 %). Frequent computed tomography findings included consolidations (68.2 %) and cavities (45.5 %) with halo signs, multiple nodules, and air crescent signs. Neutropenia was noted in five patients, including one case of agranulocytosis. Impaired renal function was observed in 59.1 % of the cases. Serum 1,3-β-D-glucan and galactomannan (GM) assays were positive in 45.5 % of patients, with bronchoalveolar lavage fluid GM tests confirming IPA in 83.3 % of those tested. Next-generation sequencing confirmed Aspergillus infection in 11 patients. Ultimately, 68.2 % of the patients recovered, whereas 31.8 % succumbed to the infection, with the deceased demonstrating a significantly high rate of complications.
Conclusions
Patients with IPA had high mortality rates. The symptoms of IPA after RT are usually nonspecific, making diagnosis very difficult. Bronchoalveolar lavage fluid GM testing and next-generation sequencing proved relatively helpful as detection methods for IPA. Antifungal treatments should be initiated as soon as possible to avoid complications.
期刊介绍:
Transplant Immunology will publish up-to-date information on all aspects of the broad field it encompasses. The journal will be directed at (basic) scientists, tissue typers, transplant physicians and surgeons, and research and data on all immunological aspects of organ-, tissue- and (haematopoietic) stem cell transplantation are of potential interest to the readers of Transplant Immunology. Original papers, Review articles and Hypotheses will be considered for publication and submitted manuscripts will be rapidly peer-reviewed and published. They will be judged on the basis of scientific merit, originality, timeliness and quality.
