Early diagnosis of cystic fibrosis (CF) through newborn screening (NBS) improves clinical outcomes, but in countries like India, delayed diagnosis increases morbidity, mortality, and likely underestimates infant deaths from CF. We performed a retrospective study at a single center in south India from 2017 to 2025 reviewing children diagnosed with CF before one year of age. Patient demographic, clinical, and genetic data were analyzed to characterize early clinical features and identify factors linked to mortality. Of 56 infants diagnosed with CF, 59% survived (median current age 55 months) while 41% died (median age of death 5 months). Key clinical indicators included sibling death with CF-like symptoms, rapid weight loss, and persistent respiratory or nutritional complications. Mortality risk under one year was significantly linked to hypoalbuminemia (OR 9.7), severe malnutrition (OR 4.4), severe anemia (hemoglobin < 7 g/dL) requiring blood transfusions (OR 3.0), and peripheral edema (OR 4.2). A triad of anemia, hypoalbuminemia, and edema was found to strongly predict death (OR 4.2). Integrating clinical checklists of these manifestations into primary healthcare may improve prompt referrals for earlier diagnosis and treatment. Continued education and advocacy for NBS are essential to reduce potentially preventable CF-related deaths in young children.
