Abstract

Aim: To evaluate whether neuroimaging‐delineated regions of hypothalamic injury are associated with a differential treatment response to a glucagon‐like peptide‐1 receptor agonist (GLP‐1RA) in patients with hypothalamic obesity (HO). Materials and Methods: We performed a prespecified secondary analysis of a randomized, multicentre, double‐blind, placebo‐controlled trial of people aged 10–25 years with hypothalamic injury and HO randomized to the GLP‐1RA exenatide once‐weekly (ExQW) or placebo for 36 weeks. Subjects underwent MRI prior to enrolment and the degree of hypothalamic damage was assessed using an integrative hypothalamic lesion score (HLS). Mammillary body (MB) damage was specifically determined. The main clinical endpoints were % change in body mass index (BMI) and change in % body fat. Nested ANCOVA models including a treatment × imaging measure interaction were compared using partial F‐tests to assess whether the effect of ExQW treatment differed by severity of hypothalamic damage. Results: Complete data were available in 35/42 randomized participants (placebo, n = 15; ExQW, n = 20). ExQW‐treated patients with worse HLS or bilateral MB damage had greater reductions in % body fat at 36 weeks (interaction coefficient estimates for HLS: −0.9%, 95% CI –1.6% to −0.2%, p = .02; for MB damage: −7.4%, 95% CI –10.1% to −4.7%, p < .001, respectively) but not for BMI % change. Similarly, patients with more damaged and smaller MB cross‐sectional areas had greater reductions in % body fat following ExQW (interaction coefficient estimate 0.3%, 95% CI 0.2%–0.4%, p < .001). Conclusions: In people with HO, greater hypothalamic damage as determined by MRI, in particular MB injury, is associated with greater reductions in adiposity following GLP‐1RA treatment.

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.
