Abstract

Abstract. Meston N, Davies RJO, Mullins R, Jenkinson C, Wass JAH, Stradling JR (University of Oxford, John Radcliffe Hospital; Oxford Centre for Respiratory Medicine and University of Oxford, Churchill Hospital; Health Services Research Unit; Oxford Centre for Diabetes, Endocrinology and Metabolism, Radcliffe Infirmary; Oxford, UK). Endocrine effects of nasal continuous positive airway pressure in male patients with obstructive sleep apnoea. J Intern Med 2003; 254: 447–454. Objective. Obstructive sleep apnoea (OSA) is a relatively common condition producing disabling somnolence and profound physiological responses to hypoxaemic episodes during sleep, including significant oscillations in blood pressure. This study aimed to provide controlled data on the interaction between OSA and endocrine axes to establish whether overrepresentation of pathology such as hypertension and hypogonadism in OSA subjects might have an endocrine basis. Design, setting and subjects. Parallel randomized sham placebo controlled 1‐month trial of nasal continuous positive airway pressure (nCPAP) in 101 male subjects with OSA presenting to a respiratory sleep clinic. Methods. Analysis of gonadotrophins, testosterone, sex hormone binding protein (SHBG), prolactin, cortisol, thyroid stimulating hormone (TSH), free thyroxine (free T4), insulin‐like growth factor‐1 (IGF‐1), renin and aldosterone were performed at baseline and after 1 month's active or placebo nCPAP intervention. Quality of life questionnaire scoring was also recorded over the same time period. Results. Testosterone and SHBG showed significant negative correlations with baseline OSA severity. Active treatment of OSA produced SHBG elevation and TSH reduction (P ≤ 0.03). Both groups showed an increase in aldosterone (P < 0.001) and IGF‐1 (P ≤ 0.03), associated with a large improvement in subjective quality of life scoring. Conclusions. These findings demonstrate significant changes in endocrine axes not previously reported in a placebo‐controlled trial. OSA is a recognized reversible cause of testosterone reduction; SHBG suppression correlating to baseline OSA severity supports a diagnosis of secondary hypogonadism. Significant rises in aldosterone and IGF‐1 on treatment coincide with increased physical activity and an improved quality of life score.

  • One-month nCPAP treatment compared to placebo resulted in a significant reduction in TSH without elevation in free T4 levels, consistent with the pattern of recovery from non-thyroidal illness.

  • Meston et al. described a small significant inverse correlation between OSAS and free T4 levels but not TSH, with no apparent association between obesity and either hormone.

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.
