Metabolomic Biomarkers for the Human Diagnosis of Neglected Tropical Diseases: A Systematic Review.
Synthesis in Revista da Sociedade Brasileira de Medicina Tropical, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Neglected tropical diseases (NTDs) affect more than 1.6 billion people worldwide and remain major contributors to morbidity, disability, stigma, and poverty. Metabolomics has emerged as a promising approach for investigating disease-associated biochemical alterations and identifying biomarkers for diagnosis, prognosis, and treatment monitoring. This systematic review evaluated the available evidence on metabolomic profiles in WHO-defined NTDs and their potential clinical applications. MEDLINE/PubMed, Web of Science, and Scopus were searched through March 2026. Observational studies investigating metabolomic profiles in human subjects with NTDs were included, and methodological quality was assessed using a modified QUADOMICS tool. Seventy-four studies met the inclusion criteria. Most were conducted in China and Brazil and focused on dengue, onchocerciasis, schistosomiasis, leprosy, and Chagas disease. Across diseases, metabolomic alterations were predominantly observed in amino acid, lipid, carbohydrate, and energy metabolism pathways. Several candidate biomarkers were identified, including N-acetyltyramine-O-β-glucuronide for onchocerciasis, bile acid derivatives for schistosomiasis, amino acids and peptides for Chagas disease, lipid mediators for leprosy, and lipid- and serotonin-related metabolites for dengue. However, most studies remained exploratory, and only two validated biomarkers in independent populations. Risk-of-bias assessment revealed frequent methodological limitations, including inadequate reporting of pre-analytical procedures, insufficient characterization of study populations, and lack of strategies to address overfitting. Human metabolomics studies were absent for several WHO-defined NTDs, highlighting major research gaps. Future research should prioritize standardized methodologies, multicenter validation studies, and greater inclusion of underrepresented diseases and endemic populations to translate metabolomic discoveries into clinically useful tools for NTD diagnosis, monitoring, and control.
