Plasmapheresis, intravenous immunoglobulins and bethametasone - a combined protocol to treat autoimmune congenital heart block: a prospective cohort study.
Bibliographic record
Abstract
OBJECTIVES: At the moment there are no standard guidelines for the treatment of autoimmune congenital heart block (CHB). We set out to carry out a prospective cohort study to evaluate the benefits, limits, and safety of a combined therapy protocol to treat antibody-related CHB. METHODS: Twelve consecutive pregnant patients positive to anti-SSA/Ro ± anti-SSB/La antibodies in whom CHB was detected were prospectively evaluated from 2009 to 2014. The treatment protocol consisted of: weekly plasmapheresis, fortnightly intravenous immunoglobulins (IVIG), and daily 4 mg betamethasone from CHB detection until delivery; IVIG was administered to the neonates soon after birth. RESULTS: At the time CHB was detected, six of the foetuses presented atrioventricular blocks of 2(nd) degree type and six of 3(rd) degree type. Two of the foetuses with a 2(nd) degree block reverted to a 1st degree block and one to a normal atrioventricular conduction. The condition was stable throughout the pregnancy in the other three cases of 2(nd) degree block. All six 3(rd) degree blocks were stable during pregnancy and confirmed at birth. After a mean of 37.6 months ± 19.6 SD post-birth, the infants with 1st, normal sinus rhythm, and 2(nd) degree blocks at birth were all found to be stable. During the follow-up (29 months ± 19.8 SD), pacemakers were implanted in three of the six infants with 3(rd) degree blocks. CONCLUSIONS: This combined therapy seems to be effective and safe in treating 2(nd) degree CHB, while its efficacy in treating 3rd degree CHB remains to be established.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
