Abstract

Probiotic strains of Lactobacillus are currently used in a variety of clinical practices with limited evidence to support their use. Lactobacillus species are a normal part of gastrointestinal flora, and bacteremia with probiotic strains of Lactobacillus is very uncommon. We describe a case of Lactobacillus bacteremia in a 17-year-old boy with ulcerative colitis managed with systemic corticosteroids and infliximab, who presented with fever to 102°F, flushing, and chills 1 week after starting Lactobacillus rhamnosus GG probiotics. Initial blood culture on day 2 of his fever was positive for Lactobacillus, however, subsequent blood cultures on day 3 and 5 were negative. He was treated empirically with antibiotics for 5 days and defervesced by day 8 of his illness. 16 S rRNA sequence analysis identified the organism from the patient's blood culture and probiotic capsule as L. rhamnosus with a 99.78% match for both the strains. This case report highlights the potential risk of Lactobacillus bacteremia in immunosuppressed patients with severe active ulcerative colitis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Our review of the literature (from 1980 to 2023) found 23 cases where the blood isolate from a bacteremic patient was identical to the probiotic strain the patient had been taking.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
