Timeline of Hospital Course:
Day 9 (day of transfer): Bronchoscopy showed friable airways and thick mucus in both lower lobes. He was started on piperacillin-tazobactam. Dexamethasone was stopped
-BAL culture grew 50,000 CFU/mL Chryseobacterium indologenes
Day 10: He was placed on veno-venous extracorporeal membrane oxygenation (ECMO)
Day 12: Leukocytosis resolved (WBC down to 8)
Day 14: Renal function progressively worsened.
Day 17: Creatinine peaked to 4.4 . Urine output was marginal, unresponsive to furosemide
Day 18: Patient was started on continuous renal replacement therapy, but became hypotensive requiring low dose norepinephrine (1 mcg/kg/min) for fluid removal.
Blood and BAL cultures were unrevealing. As per UPMC protocol, surveillance fungal biomarkers with BDG and GM were obtained. BAL culture grew <5.000 CFU/mL Gram negative rods; fungal culture was negative.
BDG = 40 pg/mL
Serum GM = 3.23
BAL GM= 9.04
Day 20: Results of GM prompted CT chest ? cavitary lung lesion RUL. Patient was started on voriconazole and caspofungin. Bronchoscopy did not show a large amount of secretions. BAL fungal culture: no growth
Day 23: Patient suffered two episodes of cardiac arrest. Family decided to make him comfort measure only
IMAGES (CAT scan of chest Day 18) – diffuse areas of ground glass opacities and traction bronchiectasis involving all lobes, and air bronchograms. There was a 3.3 x 2.7 cm cavitary lesion within the right upper lobe
AUTOPSY: The lungs were severely congested with diffuse hemorrphage and parenchymal consolidations. There was a 2.5 x 2.0 x 2.0 cm tan-brown, cavitary lesion in the right upper lobe. Microscopic sections showed extensive invasive branching hyphal structures, acute inflammation, and necrosis.
