    This prospective cross-sectional study evaluated the diagnostic and prognostic role of cerebrospinal fluid (CSF) tumor necrosis factor-alpha (TNF-a) in children with cerebral malaria (CM) and its role in the differentiation of CM from non-cerebral severe malaria. CSF TNF-a was measured using a human TNF-a enzyme-linked immunosorbent assay kit of 39 cases of CM and 19 cases of non-cerebral severe malaria. CSF TNF-a levels were significantly higher in CM (p < 0.001). Based on the receiver operating characteristics curve, a cutoff value of CSF TNF-a was 5.7 pg/ml for diagnosis of CM with sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 87.2%, 94.7%, 97.1% and 78.3% respectively. The cutoff value of CSF TNF-a was 13.7 pg/ml for predicting adverse outcomes in CM with sensitivity, specificity, PPV and NPV of 100%, 96.8%, 88.9% and 100%, respectively. However, the cutoff value of CSF TNF-a was 4.96 pg/ml for predicting adverse outcomes in non-cerebral severe malaria with a sensitivity, specificity, PPV and NPV of 100%, 94.1%, 88.9% and 100% respectively. So, CSF TNF-a is an excellent biomarker and can be used as a diagnostic and prognostic tool. More studies are needed to establish CSF TNF-a as a predictor of neurological sequelae. � The Author(s) [2023]. Published by Oxford University Press. All rights reserved.
