INTRODUCTION:

We present a case of Eggerthella bacteremia in a patient with COVID-19. CASE PRESENTATION A 69-year-old woman presented to the emergency room with chief complaint of cough, dyspnea, and malaise. After testing positive with a home COVID-19 test three days earlier, she continued to have worsening respiratory status and was brought in via ambulance. She was found to be tachycardic and hypoxic, requiring high-flow oxygen to maintain saturation in the emergency department. Chest X-ray showed bilateral patchy opacities consistent with multifocal COVID-19 pneumonia, and she was admitted to the intensive care unit for acute hypoxic respiratory failure. COVID-19 drug therapy was initiated, including baricitinib, remdesivir and decadron. Shortly after hospitalization, she began to endorse worsening abdominal pain. Physical exam elicited tenderness to palpation of her right lower quadrant. Abdominal CT scan showed distal ileum fluid collection concerning for possible bowel perforation. She underwent exploratory laparotomy which confirmed perforation, and a small bowel resection with anastomosis was performed. Blood cultures were positive for gram-positive bacilli, which were further identified as Eggerthella species. She required mechanical ventilation for worsening respiratory function post-surgery but remained unresponsive on the ventilator. The patient was administered vancomycin but continued to decline and eventually expired.

DISCUSSION:

Eggerthella is an anaerobic, gram-positive bacilli present in the gut microflora. Eggerthella infection has most often been reported in intra-abdominal infections. However, cases of bacteremia infection remain sparse. Most infections have been associated with other gastrointestinal processes including Crohn's disease, ulcerative colitis, appendicitis, and diverticulitis abscesses. Our case involved a patient with no significant gastrointestinal history admitted for COVID-19 pneumonia infection on baricitinib complicated by bowel perforation and bacteremia. Bowel perforation is a known risk factor of baricitinib use, and these risks should be discussed with the patient before beginning therapy. Overall mortality for Eggerthella species infection remains high, with some estimates as high as 31%. Much remains unknown about the impact on gut microbiome by SARS-CoV-2, however, early research suggests a higher rate of fungal co-infection in patients with COVID-19. As the literature on COVID-19 expands, more and more unusual pathogens such as Eggerthella may be found to contribute to the morbidity and mortality of patients being treated for COVID-19.

CONCLUSIONS:

Unusual pathogens such as Eggerthella may complicate a patient's hospital course while undergoing treatment for COVID-19.
