Abstract

Polymorphonuclear neutrophils are critical for resolution of bacterial infections. In tissues, most of the neutrophils quickly die through apoptosis. Using propidium iodide DNA staining and DNA gel electrophoresis, we found that spontaneous apoptosis of neutrophils from patients suffering osteomyelitis (n= 52) was significantly decreased in relation to control neutrophils (n= 20) (40.2% ± 25.2% versus 54.5% ± 23.5%;P< 0.03). Incubation of neutrophils from normal volunteers with sera from patients with osteomyelitis reduced apoptosis from 79.1% ± 14.8% in control sera to 62.2% ± 18.7% in osteomyelitis sera. A significant increase of serum interleukin-6 (IL-6) and IL-1α was found in osteomyelitis (IL-6, 8.8 ± 11.9 pg/ml versus 1.8 ± 1.2 pg/ml in controls [P< 0.004]; IL-1α, 3.8 ± 6.4 pg/ml versus 1.0 ± 2.2 pg/ml in controls [P< 0.02]). No differences in the levels of other cytokines, such as tumor necrosis factor alpha, were found. There was an inverse correlation between IL-6 levels and neutrophil apoptosis (r= −0.855;P< 0.007), but this was not the case for other cytokines. The antiapoptotic effect of the osteomyelitis sera was reversed with anti-IL-6 antibodies (P< 0.03) and was reproduced with recombinant human IL-6 (P< 0.001). The longer life span of neutrophils in osteomyelitis induced by IL-6 could contribute to the tissue damage that occurs in these chronic bone infections.

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.
