Nickel Sensitization, Hand Eczema, and Loss-of-Function Mutations in the Filaggrin Gene
Bibliographic record
Abstract
Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease. Recently, it was demonstrated that a large proportion of individuals with AD have an epidermal expression deficiency of filaggrin (FLG). This unique finding may have great implications for our understanding of nickel sensitization because nickel is chelated in the epidermis and perhaps to FLG. This review aims to briefly present the current knowledge about nickel sensitization in relation to FLG deficiency and speculate on its possible implications. The new knowledge concerning loss-of-function mutations in the FLG gene (the lack of specific nickel-chelating power in the stratum corneum and a generally defective skin barrier) suggests that an additive effect from irritants and nickel may aggravate hand eczema in individuals with loss-of-function mutations in the FLG gene. This hypothesis calls for a reevaluation of the potential risk of nickel sensitization through the establishment of cohorts with and without such mutations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
