Abstract

Background

Invasive Candida infections (ICI) are the most common invasive fungal infections in solid organ transplant recipients. There are limited contemporary data on the risk factors for infection in heart transplant (HT) recipients especially since the expansion of temporary mechanical circulatory support (MCS) use.

Methods

This was a case-control study conducted at a tertiary care academic hospital of HT recipients from January 2022 to January 2024. All patients who developed ICI by the detection of Candida species from a normally sterile site were included as cases. Four controls who underwent HT, two before the case and two after the case, were selected. ​Fisher's exact or Mann-U-Whitney tests were used for the analysis.

Results

There were 12 cases and 48 controls out of a total of 117 transplants during the study period​. The proportion of ICI was 10.6%. The median time to ICI from transplant was 16 days (IQR 10, 83). The most common organisms isolated were Candida parapsilosis and Candida albicans. The majority of infections were mediastinitis. Risk factors for ICI included receipt of antibiotics for more than 7 days within 1 month prior to transplant (58.3% vs. 22.9%, p = 0.03), tracheostomy (41.7% vs. 10.4%, p = 0.02), prolonged chest tube placement (13 vs. 9 days, p = 0.02), and temporary MCS (p = 0.042). Patients who developed ICI had increased 90-day all-cause mortality compared to controls (33.3% vs. 4.2%, p = 0.01).

Conclusion

This study identified several risk factors for ICI following HT. Further research is essential to develop interventions that mitigate these risk factors in this patient population.

期刊介绍: Clinical Transplantation: The Journal of Clinical and Translational Research aims to serve as a channel of rapid communication for all those involved in the care of patients who require, or have had, organ or tissue transplants, including: kidney, intestine, liver, pancreas, islets, heart, heart valves, lung, bone marrow, cornea, skin, bone, and cartilage, viable or stored. Published monthly, Clinical Transplantation’s scope is focused on the complete spectrum of present transplant therapies, as well as also those that are experimental or may become possible in future. Topics include: Immunology and immunosuppression; Patient preparation; Social, ethical, and psychological issues; Complications, short- and long-term results; Artificial organs; Donation and preservation of organ and tissue; Translational studies; Advances in tissue typing; Updates on transplant pathology;. Clinical and translational studies are particularly welcome, as well as focused reviews. Full-length papers and short communications are invited. Clinical reviews are encouraged, as well as seminal papers in basic science which might lead to immediate clinical application. Prominence is regularly given to the results of cooperative surveys conducted by the organ and tissue transplant registries. Clinical Transplantation: The Journal of Clinical and Translational Research is essential reading for clinicians and researchers in the diverse field of transplantation: surgeons; clinical immunologists; cryobiologists; hematologists; gastroenterologists; hepatologists; pulmonologists; nephrologists; cardiologists; and endocrinologists. It will also be of interest to sociologists, psychologists, research workers, and to all health professionals whose combined efforts will improve the prognosis of transplant recipients.
