OBJECTIVES: To determine the benefits of Lactobacillus rhamnosus GG (LGG) in an extensively hydrolyzed casein formula (EHCF) in improving hematochezia and fecal calprotectin over EHCF alone. STUDY DESIGN: Fecal calprotectin was compared in 30 infants with hematochezia and 4 weeks after milk elimination with that of a healthy group. We also compared fecal calprotectin and hematochezia on 26 formula-fed infants randomly assigned to EHCF with LGG (Nutramigen LGG) (EHCF + LGG) or without (Nutramigen) (EHCF - LGG) and on 4 breastfed infants whose mothers eliminated dairy. RESULTS: Fecal calprotectin in those with hematochezia was significantly higher than in comparisons (mean +/- SD 325.89 +/- 152.31 vs 131.97 +/- 37.98 microg/g stool, t = 6.79, P<.0001). At 4 weeks, fecal calprotectin decreased to 50% of baseline but was still significantly higher than in comparisons (157.5 +/- 149.13 vs 93.72 +/- 36.65 microg/g, P = .03). Fecal calprotectin mean decrease was significantly larger among EHCF + LGG compared with EHCF - LGG (-214.5 +/- 107.93 vs -112.7 +/- 105.27 microg/g, t = 2.43, P = .02). At 4 weeks, none of the EHCF + LGG had blood in stools, and 5/14 on EHCF - LGG did (P = .002). CONCLUSION: Fecal calprotectin is elevated in infants with hematochezia and possible allergic colitis. EHCF + LGG resulted in significant improvement of hematochezia and fecal calprotectin compared with the EHCF alone.
