Abstract

This study reports on a group of 20 patients with an initial diagnosis of primary biliary cirrhosis (PBC) whose serum tested negative for antimitochondrial antibodies by immunofluorescence. All had a clinical history compatible with primary biliary cirrhosis, and results of biochemical, histological, and radiological investigations were consistent with this diagnosis despite the absence of antimitochondrial antibodies by immunofluorescence. For comparison, these patients were matched for sex and serum bilirubin with 20 antimitochondrial antibody positive (> 1:160) and histologically confirmed primary biliary cirrhosis patients who served as controls. Serum samples from both groups were retested blindly for antimitochondrial antibodies using immunoblotting and for antibodies to the major M2 mitochondrial autoantigens by enzyme linked immunosorbent assay (ELISA). Three antimitochondrial antibody immunofluorescence negative patients had antimitochondrial antibodies by immunoblotting and ELISA; the remaining 17 patients were confirmed negative by all methods. The antimitochondrial antibody immunofluorescence positive controls were verified by immunoblotting or ELISA, or both. All 17 patients negative for antimitochondrial antibodies had antinuclear antibodies, often in high titres, compared with 3/17 of the antimitochondrial antibody positive controls (p = 0.0001). Additionally, the antimitochondrial antibody negative group also had significantly higher smooth muscle antibody titres (p = 0.03) and lower serum IgM (p = 0.01) and aspartate aminotransferase (p = 0.03) activities than the antimitochondrial antibody positive controls. Analysis of clinical findings, histological tests, serum bilirubin, alkaline phosphatase, alanine aminotransferase, and IgG, disclosed no significant differences between the two groups. This paper describes a group of patients with the clinical and histological features of PBC but who do not fulfil the usual criteria necessary to make this diagnosis. Because they also have very high titres of antinuclear antibodies, smooth muscle antibodies, and comparatively low IgM and aspartate aminotransferase activities, we believe they are distinct from PBC and have a syndrome of autoimmune cholangitis.

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.
