The apolipoprotein E2 isoform is associated with accelerated onset of coronary artery disease in systemic lupus erythematosus.
Bibliographic record
Abstract
BACKGROUND: Systemic lupus erythematosus (SLE) is a highly prevalent autoimmune disease and coronary artery disease (CAD) is a complication of SLE which is often crucial for the patient's prognosis. It is hypothesized that apolipoprotein E (Apo E), which is involved in cholesterol metabolism, might play a role in this process. MATERIAL/METHODS: Patients with SLE registered at the University of Toronto Lupus Clinic who had DNA available for study had their Apo E genotype determined. Each case was assessed for the presence of CAD, and Apo E allele frequencies in patients with SLE were compared with data from the general population. Age at onset and disease duration of CAD were also recorded and compared between groups. RESULTS: DNA was stored from 152 patients, of whom 38 (25%) had CAD. There was no difference in the frequencies of the Apo E isoforms between SLE patients and the general population. Patients with the E2 allele developed CAD after a mean +/-SD of 6.0+/-1.9 yrs compared with 14.5+/-5.4 yrs in those with E3/3 (p<0.01). CONCLUSIONS: The distribution of Apo E genotypes in SLE is not significantly different from that of the North American population. In SLE, Apo E2 was associated with a more rapid development of CAD. Therefore, Apo E2 might interact with other disease-related factors to accelerate the onset of CAD in some patients with SLE and as such might be an additional marker of risk in this population.

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.
