Identification of Irpex and Rhodotorula on surveillance bronchoscopy in a pediatric lung transplant recipient: A case report and review of literature of these atypical fungal organisms.

BACKGROUND: Invasive fungal disease (IFD) is a frequent complication in pediatric lung transplant recipients, occurring in up to 12% of patients in the first year. Risk factors for infection include impaired lung defenses and intense immunosuppressive regimens. While most IFD occurs from Aspergillus, other fungal conidia are continuously inhaled, and infections with fungi on a spectrum of human pathogenicity can occur. CASE REPORT: We report a case of a 17-year-old lung transplant recipient in whom Irpex lacteus and Rhodotorula species were identified during surveillance bronchoscopy. She was asymptomatic and deemed to be colonized by Irpex lacteus and Rhodotorula species following transplant. 2 years after transplantation, she developed a fever, respiratory symptoms, abnormal lung imaging, and histological evidence of acute and chronic bronchitis on transbronchial biopsy. After developing symptoms concerning for a pulmonary infection and graft dysfunction, she was treated for a presumed IFD. Unfortunately, further diagnostic testing could not be performed at this time given her tenuous clinical status. Despite the initiation of antifungal therapy, her graft function continued to decline resulting in a second lung transplantation. CONCLUSIONS: This case raises the concern for IFD in lung transplant recipients from Irpex species. Further investigation is needed to understand the pathogenicity of this organism, reduce the incidence and mortality of IFD in lung transplant recipients, and refine the approach to diagnosis and manage the colonization and isolation of rare, atypical fungal pathogens in immunocompromised hosts.

Expectations versus reality: Understanding the accuracy of impressions made during virtual interviews of pediatric pulmonary fellowship programs.

RATIONALE: As a result of the SARS-CoV-2 pandemic, all pediatric pulmonary fellowship programs conducted virtual interviews for the first time in the Fall of 2020. This study aimed to understand the accuracy of virtual-interview derived-impressions of fellowship programs, as well as applicant preference for future fellowship interview cycles. METHODS: A group of pediatric pulmonary fellows and Program Directors designed a REDCap survey. The survey was distributed to all first-year pediatric pulmonary fellows who participated in the 2020-2021 virtual interview season. RESULTS: 23/52 (44%) of first-year pediatric pulmonary fellows completed the survey. 96% were able to form general impressions about fellowship programs during their virtual interviews. 96% reported that generally their fellowship experience matched their virtual-interview derived-impressions. 17 of the 19 factors applicants use to rank programs had no statistically significant change (p > 0.05) in impression from virtual interview to fellowship experience. The two factors with a statistically significant (p < 0.05) change in impression were patient care related-volume of "bread and butter" pediatric pulmonary patients and volume of tertiary care pediatric pulmonary patients. 87% prefer some form of in-person interview option in future application cycles. A tiered interview format in which applicants are first invited to a virtual interview day followed by an optional in-person second look day was the most popular preference for future interview cycles (48%). CONCLUSIONS: Virtual interviews may provide accurate representations of pediatric pulmonary fellowship programs and applicants prefer some type of in-person interview option in future application cycles.
