Abstract

Inappropriate responses to respiratory viruses, especially rhinovirus, and early allergic sensitization are the strongest contributors to the inception and persistence of early onset asthma. The ORMDL3 asthma locus in chromosome 17q seems to exert its effects by increasing susceptibility to human rhinovirus in early life. Being raised on animal farms is highly protective against the development of asthma, and this protective effect is mediated by exposure to microbes. Two trials in high-risk young children, one to prevent wheezing lower respiratory tract illness using bacterial lyophilizates and another using anti-immunoglobulin E to prevent asthma progression, are already under way.

  • In early life, a period critical for immune development, environmental microbial diversity appears protective against allergic sensitization and asthma.

    “In early life, a period critical for immune development, environmental microbial diversity appears protective against allergic sensitization and asthma (77, 81, 82).”

    From Indoor Allergen Interventions in Homes and Schools for Managing Asthma (2025) · cites this paper as [82]

    In “Animal farming and early onset asthma” (page unavailable), the paper reports that children raised on animal farms had lower risks of early-onset asthma and allergic sensitization, and suggests that exposure to environmental bacteria and fungi may explain the protection. It discusses the timing of microbial exposure and immune maturation in “Human microbiome and the inception of early onset asthma,” but describes environmental microbial burden, not diversity specifically, as the proposed protective factor.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
