High doses of short-term testosterone have been shown to acutely worsen sleep-disordered breathing in men with obstructive sleep apnoea (OSA). The effects of lower, near-conventional doses of testosterone in obese men with OSA may differ over the longer term but have not been systematically studied. We assessed sleep and breathing effects of near-conventional testosterone treatment as an adjunct to weight loss in obese men with severe OSA.
An 18-week randomized, double-blind, placebo-controlled, parallel group trial in 67 men.
All subjects were placed on a hypocaloric diet and then received intramuscular injections of 1000 mg testosterone undecanoate or placebo at 0, 6 and 12 weeks.
Sleep and breathing were measured by nocturnal polysomnography at 0, 7 and 18 weeks. Testosterone, compared to placebo, worsened the oxygen desaturation index (ODI) by 10·3 events/h (95%CI, 0·8-19·8 events/h; P = 0·03) and nocturnal hypoxaemia (sleep time with oxygen saturation <90%, SpO(2) T90%) by 6·1% (95%CI, 1·5-10·6; P = 0·01) at 7 weeks. Testosterone therapy did not alter ODI (4·5, -5·4 to 14·4 events/h; P = 0·36) or SpO(2) T90% at 18 weeks (2·9, -1·9-7·7%; P = 0·23) compared to placebo. The testosterone treatment effects on ODI and SpO(2) T90% were not influenced by baseline testosterone concentrations (testosterone by treatment interactions, all P > 0·35). Blood testosterone concentrations did not correlate with ODI or SpO(2) T90% (all P > 0·19).
Testosterone therapy in obese men with severe OSA mildly worsens sleep-disordered breathing in a time-limited manner, irrespective of initial testosterone concentrations. This time-dependency was not related to testosterone concentrations.

已有研究表明,短期大剂量睾酮可使阻塞性睡眠呼吸暂停(OSA)患者的睡眠呼吸紊乱急性恶化。但对于肥胖的 OSA 患者,较低的常规剂量睾酮可能会在较长时间内产生不同的影响,而这些影响尚未得到系统研究。我们评估了在严重 OSA 的肥胖男性中,将常规剂量的睾酮作为减肥的辅助手段对睡眠和呼吸的影响。
这是一项为期 18 周的、随机、双盲、安慰剂对照、平行组试验,共纳入了 67 名男性。
所有受试者均接受低热量饮食,然后在 0、6 和 12 周时接受肌内注射 1000mg 十一酸睾酮或安慰剂。
在 0、7 和 18 周时通过夜间多导睡眠图测量睡眠和呼吸情况。与安慰剂相比,睾酮使氧减饱和指数(ODI)恶化了 10.3 次/小时(95%CI,0.8-19.8 次/小时;P=0.03),使夜间低氧血症(睡眠时血氧饱和度<90%,SpO2T90%)恶化了 6.1%(95%CI,1.5-10.6;P=0.01),这些变化在第 7 周时发生。与安慰剂相比,睾酮治疗并未改变 ODI(4.5,-5.4 至 14.4 次/小时;P=0.36)或 SpO2T90%(2.9,-1.9-7.7%;P=0.23)在第 18 周时发生。ODI 和 SpO2T90%的睾酮治疗效果不受基线睾酮浓度的影响(治疗与睾酮相互作用,所有 P>0.35)。血睾酮浓度与 ODI 或 SpO2T90%无相关性(所有 P>0.19)。
在严重 OSA 的肥胖男性中,睾酮治疗会在有限的时间内轻度恶化睡眠呼吸紊乱,而与初始睾酮浓度无关。这种时间依赖性与睾酮浓度无关。
