Catch-up Growth in Severe Juvenile Hypothyroidism: Treatment with a GnRH Analog
Bibliographic record
Abstract
Anecdotal reports suggest that the addition of a gonadotropin releasing hormone (GnRH) analog (GnRHa) in addition to L-thyroxine (LT4) replacement may increase adult stature in children with severe longstanding hypothyroidism by prolonging the pubertal growth period. This retrospective chart review compares the height outcome and body mass index in 33 children (21 treated with LT4 alone and 12 treated with LT4 + GnRHa) with severe longstanding hypothyroidism and bone age delay. Seventeen controls and six GnRHa-treated patients were followed to adult height (BA >14 yr [F]/16 yr [M] and/or growth velocity < 2 cm/yr). At diagnosis, GnRHa-treated patients were 1) older and shorter for chronological age, and 2) more advanced in puberty and bone age. Despite these differences, at adult height, both groups had similar improvements in height Z scores, similar height deficits, and comparable adult heights. Changes in BMI Z score were similar for both groups. Our study suggests that the addition of GnRHa to LT4 may improve interval growth without imposing a risk of obesity in children with longstanding severe hypothyroidism.

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.
