Emergence of Clonally-Related South Asian Clade I Clinical Isolates of Candida auris in a Greek COVID-19 Intensive Care Unit

Candida auris has recently emerged as a multidrug-resistant yeast implicated in various healthcare-associated invasive infections and hospital outbreaks. In the current study, we report the first five intensive care unit (ICU) cases affected by C. auris isolates in Greece, during October 2020-January 2022. The ICU of the hospital was converted to a COVID-19 unit on 25 February 2021, during the third wave of COVID-19 in Greece. Identification of the isolates was confirmed by Matrix Assisted Laser Desorption Ionization Time of Flight mass spectroscopy (MALDI-TOF]. Antifungal susceptibility testing was performed by the EUCAST broth microdilution method. Based on the tentative CDC MIC breakpoints, all five C. auris isolates were resistant to fluconazole (≥32 μg/mL), while three of them exhibited resistance to amphotericin B (≥2 μg/mL). The environmental screening also revealed the dissemination of C. auris in the ICU. Molecular characterization of C. auris clinical and environmental isolates was performed by MultiLocus Sequence Typing (MLST) of a set of four genetic loci, namely ITS, D1/D2, RPB1 and RPB2, encoding for the internal transcribed spacer region (ITS) of the ribosomal subunit, the large ribosomal subunit region and the RNA polymerase II largest subunit, respectively. MLST analysis showed that all isolates possessed identical sequences in the four genetic loci and clustered with the South Asian clade I strains. Additionally, PCR amplification and sequencing of the CJJ09_001802 genetic locus, encoding for the "nucleolar protein 58" that contains clade-specific repeats was performed. Sanger sequence analysis of the TCCTTCTTC repeats within CJJ09_001802 locus also assigned the C. auris isolates to the South Asian clade I. Our study confirms that C. auris is an emerging yeast pathogen in our region, especially in the setting of the ongoing COVID-19 worldwide pandemic. Adherence to strict infection control is needed to restrain further spread of the pathogen.

Adrenal gland injury after blunt abdominal trauma: Two case series and review of the literature

INTRODUCTION

Adrenal gland injury (AGI) is a rare form of trauma that is often misdiagnosed, especially if isolated.

PRESENTATION OF CASE

Herein we describe two rare cases of adrenal hematoma (AH) and adrenal contusion due to blunt abdominal trauma. A 33-year-old Caucasian male who was transported to the emergency department after a low-speed motorbike accident and a 69-year old Caucasian female who fell from 50 cm height. Both where complaining of intense pain in the right flank. Neither were under anti-coagulant or anti-platelet therapy. In both patients thoracoabdominal CE-CT revealed the injury.

DISCUSSION

AGI is an uncommon finding in blunt trauma and isolated adrenal injuries usually result from low force accidents. Treatment is most commonly conservative, but depends on patient's status. In Greece, to our knowledge, these are the first such cases reported in adults.

CONCLUSION

Diagnosis needs high level of clinical suspicion.
