Bacillus cereus infection in pediatric oncology patients: A case report and review of literature

Sunisha Arora et al. IDCases. .

Abstract

Introduction: Bacillus Cereus infection can be life-threatening in immunocompromised patients. We report here a case of Bacillus Cereus septicemia in a child with relapsed acute lymphoblastic leukemia (ALL) and present review of literature.

Methods: We collected clinical, laboratory and outcome data of our patient with relapsed ALL and Bacillus Cereus infection. We reviewed literature for Bacillus Cereus infection in pediatric oncology patients by searching MED-LINE/PubMed/Google/Google Scholar/Cochrane and summarized the data obtained. Various risk factors like presence of gastrointestinal or central nervous system (CNS) symptoms, neutropenia, central venous catheter in-situ, corticosteroids use, intrathecal chemotherapy and outcomes were analyzed using Fisher Exact Chi Square test.

Results: A 15-years-old boy with relapsed ALL on induction chemotherapy presented with giddiness and difficulty in breathing. He had an episode of hematemesis followed by fainting at home. He had refractory shock which did not respond to fluid boluses, inotropes and hydrocortisone. He had severe metabolic acidosis with high lactate and ammonia and died within 36-hours of onset of symptoms. His blood culture was positive for Bacillus Cereus. We came across 36 published cases of Bacillus Cereus in children with cancer including present case. Of these, 28 had acute leukemia and rest 8 had other cancers. CNS symptoms were present in 13 patients. Overall mortality was 25%. Patients with multisystem involvement had significantly higher mortality compared to those having localized disease (p-value 0.033).

Conclusion: In pediatric oncology patients on chemotherapy, cultures positive for Bacillus Cereus should be considered significant. Mortality is higher in those with multisystem involvement.

Keywords: Bacillus Cereus; Leukemia; Pediatric Oncology.
