Green Banana Mixed Diet is Beneficial in the Management of Childhood Persistent Diarrhea: An Open, Randomized-Controlled Trial

Background: Persistent diarrhea (PD), diarrhea for ≥14 days, accounts for 36%-56% of all diarrhea-related death. Studies demonstrated that green banana helps in the resolution of diarrhea. We assessed whether a lactose-free diet rice suji (RS) or rice suji containing green banana (GB-RS), improves outcome compared with 3/4th strength rice suji (3/4th RS) in 6 to 35 months old children having PD in the icddr,b Dhaka hospital. Methods: In this open-labeled, randomized, controlled trial, children with PD not improving with milk suji (the initial diet) received any of the three study diets: GB-RS, RS, 3/4th RS. The primary outcome was the percentage of children who recovered from diarrhea by day 5 with an intention to treat analysis. Findings: From 1st December 2017 to 31st August 2019, we randomly allocated 45 children to each group. By day 5, 66 children recovered from PD, of whom 26 (58%), 14 (31%), 26 (58%) received GB-RS, RS, and 3/4th RS respectively. Significantly more resolution of PD occurred in GB-RS and 3/4th RS groups compared to RS group [relative risk (RR) 1⸱71, 95% CI 1⸱19-2⸱60; p=0⸱019]. Two (10%) children died, one each in RS group and GB-RS group. TaqMan array card (TAC) identified EAEC, rotavirus, norovirus, EPEC, astrovirus, and Campylobacter as the major pathogens associated with PD. Interpretation: GB-RS and 3/4th RS are efficacious in the management of PD in young children. We also demonstrated a wide range of entero-pathogen associated with PD by TAC which needs further study to find a causal link.
