BACKGROUND: A 6-food elimination diet in pediatric eosinophilic esophagitis (EoE) is difficult to implement and may negatively affect quality of life (QoL). Less restrictive elimination diets may balance QoL and efficacy.
OBJECTIVE: We performed a multisite, randomized comparative efficacy trial of a 1-food (milk) elimination diet (1FED) versus 4-food (milk, egg, wheat, soy) elimination diet (4FED) in pediatric EoE.
METHODS: Patients aged 6 to 17 years with histologically active and symptomatic EoE were randomized 1:1 to 1FED or 4FED for 12 weeks. Primary end point was symptom improvement by Pediatric Eosinophilic Esophagitis Symptom Score (PEESS). Secondary end points were proportion experiencing histologic remission (<15 eosinophils per high-power field); change in histologic features (histology scoring system), endoscopic severity (endoscopic reference score), transcriptome (EoE diagnostic panel), and QoL scores; and predictors of remission.
RESULTS: Sixty-three patients were randomly assigned to 1FED (n = 38) and 4FED (n = 25). In 4FED versus 1FED, mean PEESS improved -25.0 versus -14.5 (P = .04), but remission rates (41% vs 44%; P = 1.00), histology scoring system (-0.25 vs -0.29; P = .77), endoscopic reference score (-1.10 vs -0.58; P = .47), and QoL scores were similar between groups. The EoE transcriptome normalized in those with histologic response to both diets. Baseline peak eosinophil count predicted remission (odds ratio, 0.975 [95% confidence interval, 0.953-0.999], P = .04; cutoff ≤42 eosinophils per high-power field). The 4FED withdrawal rate (32%) exceeded that of 1FED (11%) (P = .0496).
CONCLUSIONS: Although 4FED moderately improved symptoms compared with 1FED, the histologic, endoscopic, QoL, and transcriptomic outcomes were similar in both groups. 1FED is a reasonable first-choice therapy for pediatric EoE, given its effects, tolerability, and relative simplicity.
