Septicemia due to Bacillus clausii after the use of probiotics. A complication to keep in mind.

UNLABELLED: Probiotics are live microorganisms that benefit the host in different clinical situations. Bacillus clausii is one of the most frequently used, but it is not without risk. To date, there are few reports of complications secondary to this agent in pediatric patients.

OBJECTIVE

To describe the case of an infant who developed after treatment sepsis due to Bacillus clausii.

CLINICAL CASE: A 4-month-old female infant of indigenous ethnicity, from a rural area in the interior of Panama, 3 hours away from the nearest health sub-center by canoe, and with protein-calorie malnutrition, presented with acute diarrhea and moderate-severe dehydration, receiving Enterogermina as part of the initial treatment. She was transferred to a tertiary hospital, where she arrived with impaired consciousness, respiratory distress, and signs of shock. The initial blood culture reported growth of methicillin-resistant Staphylococcus aureus (MRSA), the gastrointestinal panel was positive for Clostridiodes difficile, and later serial blood cultures of peripheral blood and central venous catheter confirmed growth of Bacillus clausii. With a torpid evolution and resistance to multiple antibiotic schemes, she died due to multisystem organ failure twelve days after admission.

CONCLUSIONS

The use of probiotics as concomitant treatment in patients with some degree of immunosuppression should be administered with caution, considering the presence of risk criteria for complications such as malnutrition or intestinal epithelial damage due to severe diarrhea since they predispose to the development of bacteremia and/or sepsis.
