Lymphocytic Infiltrates in the Spinal Cord in Amyotrophic Lateral Sclerosis

Engelhardt, J. I., Tajti, J., Appel, S. H.·1993·Archives of Neurology

Abstract

Objective Immunohistochemical examination was undertaken to assess the presence of lymphocytes and lymphocyte subsets in the spinal cord in amyotrophic lateral sclerosis (ALS). Design Twenty-seven consecutive ALS autopsy cases and 11 consecutive disease--control autopsy cases were examined. Tissue sections were reacted with mouse monoclonal antibody to human leukocyte common antigen, or monoclonal antibody to human B-cell L26 antigen, and detected with immunoperoxidase techniques. Unfixed sections were reacted with antihuman Leu-3a and Leu-3b/CD4 or antihuman Leu-2a/CD8 mouse monoclonal antibody and then detected with peroxidase techniques. Setting Tertiary care hospital. Cases Amyotrophic lateral sclerosis and non-ALS control autopsy specimens. Main outcome measure Detection of lymphocytes by histological and immunohistochemical reactivity. Results Perivascular and intraparenchymal lymphocytic infiltrates were found in the spinal cord of 18 of 27 consecutive ALS autopsy cases. The lymphocytes possessed only T-cell markers; no B-cell markers could be demonstrated. T-helper cells were found in proximity to degenerating corticospinal tracts, while T-helper and T-suppressor/cytotoxic cells were demonstrated in ventral horns. Lymphocytes were present in the spinal cord of only one control specimen (multiple sclerosis) and in none of the remaining 10 control specimens. In ALS tissue, the lymphocytic infiltrates did not correlate with the rate of progression or stage of the disease…

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?

  • Blood-brain barrier and blood-spinal cord barrier are damaged in a subset of amyotrophic lateral sclerosis patients, with plasma-derived IgG accumulation in spinal cord and motor cortex in 40-90% of cases and peripheral blood cell accumulation in 70-100% of cases.

    “These findings support earlier observations showing that the BBB and BSCB are damaged in a subset of ALS patients as demonstrated by accumulation of plasma-derived IgG in the spinal cord and motor cortex in 40% (154) to 90% (163) of studied cases, and accumulation of peripheral blood cells in 70% (164) to 100% (599) of studied cases.”

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.
