Abstract

Background Calprotectin (complex of S100A8 and S100A9) is the major calcium and zinc-binding protein of phagocytes. We report a new syndrome with recurrent infections, inflammation, and hyperzincaemia associated with excessively high plasma concentrations of calprotectin.Methods We measured calprotectin in plasma and protein fractions by ELISA assay and zinc by atomic absorption spectrometry. Plasma proteins were fractionated by size exclusion chromatography and electrophoresis. Mass spectra of purified proteins were determined by MALDI-TOFMS.Findings We assessed five patients, two of whom are related. All patients had much the same biochemical findings of hyperzincaemia (77-200 micromol/L, reference range 11-18 micromol/L) and raised plasma calprotectin concentrations (1.4-6.5 g/L, reference range <1 mg/L). All patients presented with recurrent infections, hepatosplenomegaly, anaemia, and evidence of systemic inflammation. Three patients had cutaneous inflammation and three presented in infancy with severe growth failure. Size exclusion chromatography showed that zinc and calprotectin were associated in a broad fraction with molecular weight range 100-300 kDa. Analysis by electrophoresis and mass spectrometry showed that the patients' protein contained normal S100A8 and S100A9 subunits.Interpretation Dysregulation of zinc metabolism associated with accumulation in plasma of S100A8 and S100A9 defines a new disease, which encompasses a pathological role for dysregulation of two members of the large S100 protein family.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Hypercalprotectinaemia is associated with increased incidence of recurrent infections.

    “however hypercalprotectinaemia, in which patients have excessive serum calprotectin, is associated with increased incidence of recurrent infections (Sampson et al., 2002).”

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.
