Assessment of CAI in Adults With PWS.

Completed
Conditions
Central Adrenal Insufficiency
Prader-Willi Syndrome
Registration Number
NCT04700644
Lead Sponsor
Medical University of Warsaw
Brief Summary

Introduction: The prevalence and clinical significance of central adrenal insufficiency (CAI) in adult patients with Prader Willi Syndrome (PWS) remains unclear.

Aim: To assess the prevalence of CAI in adults with PWS and to analyse the effects of replacement therapy with hydrocortisone (HCT) in patients with suspected CAI.

Material and Methods: Twenty one adult patients with PWS were evaluated. Based on peak cortisol at the 30 minute of the high dose short Synacthen test (HDSST), patients were divided into three groups: CAI (central adrenal insufficiency) - peak cortisol \<500nmol/L, intermediate (partial AI) - peak cortisol ≥500 nmol/L and \<600 nmol/L and AS (adrenal sufficiency) - peak cortisol ≥ 600 nmol/L. In patients with diagnosed CAI HCT replacement treatment was initiated. Body weight, body fat percentage, signs, and symptoms of CAI were evaluated after 6 and 12 months of treatment.

Primary Outcome Measures
NameTimeMethod
The prevalence of CAI in adult PWS patients based on HDSST.At first visit (before HCT treatment).

The diagnosis of CAI was based on the high-dose short Synacthen test (HDSST). The following cut-off points were used:

1. CAI group (suspected CAI):

• cortisol \< 500 nmol/L at the 30th minute

2. AS group (adrenal sufficiency - CAI excluded):

• cortisol ≥ 600 nmol/L at the 30th minute

3. Intermediate group • cortisol ≥500 nmol/L and \<600 nmol/L at the 30th minute
