Clinically active serologically quiescent systemic lupus erythematosus.
Bibliographic record
Abstract
OBJECTIVE: To identify the frequency and characteristics of clinical activity with serological quiescence (CASQ) in a large cohort of patients with systemic lupus erythematosus (SLE) followed prospectively at a single center. METHODS: Patients followed at the Lupus Clinic between 1991 and 1995 who on at least 3 consecutive visits had clinical activity in the absence of a low complement and elevated DNA binding were identified. Demographics, disease characteristics, and therapy for the CASQ periods, as well as prior and subsequent disease course until April 2002 were analyzed. RESULTS: Of 514 patients followed at the Lupus Clinic according to a standard protocol, 62 patients had at least one episode of CASQ lasting a 9.8 +/- 6.4 months. During these periods, patients showed evidence of clinical disease activity with a SLEDAI-2K of 8.9 +/- 5.3. Major organ involvement (central nervous system, renal, vasculitis) occurred in 43 patients. Forty-four patients were treated with prednisone 16.7 +/- 11.4 mg/day, 21 were on immunosuppressive medication and 30 on antimalarials. Of the 58 patients who had followup after their last CASQ defining visit, 9 remained CASQ for 39 +/- 23 months. Of the remaining 49 patients, 23 became inactive, 21 became clinically and serologically active, and 5 were serologically active but clinically quiescent (SACQ). CONCLUSION: Clinical laboratory correlation in SLE is a heterogeneous relationship. The majority of patients have clinical-serological concordance. The minority have discordance between clinical and serological status, and are either SACQ or CASQ. Therefore, monitoring both clinical and serological features in patients with SLE is important.

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.
