1 · What the graph read from 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.

2 · The registry

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

backgroundMolecular forms of allergen-specific immunotherapy (AIT) for cat allergy are needed. Fel d 1, Fel d 4, and Fel d 7 are the most important cat allergens.

methodsIgE epitopes of Fel d 4 and Fel d 7 were mapped by blocking allergic patients' IgE binding with allergen peptide-specific antisera. Five recombinant fusion proteins (PreS-Cat 1-PreS-Cat 5) each containing hepatitis B virus (HBV)-derived PreS as an immunological carrier and non-allergenic peptides from the IgE binding sites of Fel d 1, Fel d 4, and Fel d 7 were expressed in Escherichia coli, purified, and characterized by mass spectrometry, circular dichroism (CD), and size exclusion chromatography. ImmunoCAP and basophil activation experiments demonstrated the hypoallergenic activity of PreS-Cat 1-5. The ability of PreS-Cat 1-5 to induce IgE-blocking antibodies in rabbits was compared to three licensed allergen extract-based AIT vaccines. PreS-Cat 1-5-specific IgG antibodies were tested for inhibition of allergen-specific IgE binding and specific basophil activation. T cell activation and induction of specific cytokine secretion by PreS-Cat proteins were compared with cat allergens in PBMC cultures.

resultsRecombinant hypoallergenic, biochemically and structurally defined PreS-Cat 1-5 were obtained. Two subcutaneous immunizations of rabbits with PreS-Cat 1-5 induced equal (Fel d 1) or better (Fel d 4 and Fel d 7) antibodies (PreS-Cat 5 > PreS-Cat 1 > PreS-Cat 3) blocking allergic patients' IgE binding to cat allergens than six to fifteen immunizations with allergen extract-based vaccines. PreS-Cat-specific antibodies strongly inhibited specific basophil activation. PreS-Cat 5 > PreS-Cat 1 induced significantly more IL-10 in cultured PBMCs from cat allergic patients than cat allergens.

conclusionsPreS-Cat 5 and PreS-Cat 1 are highly promising molecular vaccine candidates for AIT of cat allergy, combining Fel d 1-, Fel d 4-, and Fel d 7-peptides in single PreS fusion proteins.
