Helminth driven gut inflammation and microbial translocation associate with altered vaccine responses in rural Uganda.
Article in NPJ vaccines, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Vaccine responses are sometimes impaired in rural, low-income settings. Helminth-associated gut barrier dysfunction and microbial translocation (MT) may be implicated. We used samples from a trial of praziquantel treatment-effects on vaccine responses in Schistosoma mansoni (Sm)-endemic Ugandan islands, measuring intestinal fatty acid-binding protein 2 (I-FABP2), lipopolysaccharide-binding protein, anti-endotoxin core antibodies (EndoCab), soluble CD14 (sCD14) in plasma, and faecal lipocalin-2, occult blood (FOB), and calprotectin (fCAL), and evaluating their associations with baseline helminth infection, praziquantel treatment, and responses to BCG, yellow fever, typhoid, HPV, and tetanus-diphtheria vaccines. Sm associated positively with fCAL and FOB, hookworm with I-FABP2, and any helminth with EndoCab IgM, fCAL and FOB. Sm associated inversely with sCD14. Praziquantel treatment reduced all marker concentrations, significantly fCAL and FOB, implying that Sm-associated gut inflammation and MT is reversible. Associations of assessed markers with vaccine-specific responses were predominantly inverse. Interventions to improve gut barrier function may enhance vaccine responsiveness.
