Abstract: During The Gambia’s 2022 diethylene glycol (DEG) outbreak, 82 children developed acute kidney injury (AKI) with 80% mortality. However, approximately 30% of children with documented DEG exposure did not develop AKI. Understanding protective factors could enable risk stratification and inform prophylactic interventions in future outbreaks. We conducted a case-case-control study among 321 children aged ≤8 years from six Gambian health regions. We compared exposed children who developed AKI (exposed-susceptible, n = 37) with exposed children who remained healthy (exposed-resistant, n = 16) and unexposed healthy children (n = 242). Multivariable logistic regression identified factors associated with AKI resistance among the 53 exposed children, adjusting for age, sex, and socioeconomic indicators. Sensitivity analyses included propensity score matching and stratification. Three factors were independently associated with reduced AKI risk: older age (adjusted OR=0.58 per year, 95% CI [0.36-0.92], p = .021), multivitamin supplementation (aOR=0.24, 95% CI [0.06-0.85], p = .028), and exposure to a single contaminated medicine (aOR=4.21 for ≥2 vs 1 medicine, 95% CI [1.12-16.85], p = .034). A dose-response relationship was observed, with AKI odds increasing 4-fold per additional contaminated medicine (p-trend = .018). Promethazine oral solution showed strongest toxicity (aOR=4.15, 95% CI [1.15-15.82]), consistent with highest DEG concentration (19.4 mg/mL). Multivitamin effects were strongest in children
