Bacterial and Parasitic Stool Studies Have Limited Utility in Pediatric Hematopoietic Stem Cell Transplant Patients.
Background: Diarrhea is a common complication among pediatric hematopoietic stem cell transplantation (HCT) recipients. Although many of the cases are secondary to graft-versus-host disease (GVHD), stool microbiological studies are often performed to evaluate an underlying infectious etiology. The aim of this study was to assess the frequency and utility of stool studies in children who have undergone HCT.
Methods: Demographics, clinical characteristics, and stool study results (viral, parasitic, and bacterial) of all patients who underwent HCT at a large, academic, freestanding children's hospital between January 2006 and December 2023 were obtained. Statistical analysis conducted included t tests, chi-square, and linear regression.
Results: Overall, 1381 HCT recipients (9.2 ± 6.6 years) were included. Altogether, 6509 stool studies were obtained among 741 (54%) patients. Salmonella, Shigella, Yersinia, Campylobacter, and Escherichia coli (SSYCE) studies were sent on 363 (26%, 2252 studies) patients with 1 (0.04%) positive result. Clostridium difficile was sent on 706 (51%, 2055 studies) patients, with 156 positive studies (7.6%). Stool ova and parasite testing was sent on 143 (10%, 242 studies) patients, with two positive results (0.8%). Viral studies were sent on 638 (46%, 1960 studies) patients, with 107 positive studies (5.5%).
Conclusions: While testing for Clostridium difficile and enteric viruses may have value in the work-up of pediatric HCT patients, SSYCE and O&P studies hold little to no value. Clinical practices surrounding routine stool microbiological studies should be reconsidered.
