Objective of this study was to assess the association between testosterone (T) levels and biochemical markers in a cohort of female patients admitted for SARS-CoV-2 infection in a respiratory intensive care unit (RICU).
A consecutive series of 17 women affected by SARSCoV-2 pneumonia and recovered in the RICU of the Hospital of Mantua were analyzed. Biochemical inflammatory markers as well as total testosterone (TT), calculated free T (cFT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were determined.
TT and cFT were significantly and positively associated with PCT, CRP, and fibrinogen as well as with a worse hospital course. We did not observe any significant association between TT and cFT with LH; conversely, both TT and cFT showed a positive correlation with cortisol. By LOWESS analysis, a linear relationship could be assumed for CRP and fibrinogen, while a threshold effect was apparent in the relationship between TT and procalcitonin, LDH and ferritin. When the TT threshold value of 1 nmol/L was used, significant associations between TT and PCT, LDH or ferritin were observed for values above this value. For LDH and ferritin, this was confirmed also in an age-adjusted model. Similar results were found for the association of cFT with the inflammatory markers with a threshold effect towards LDH and ferritin with increased LDH and ferritin levels for values above cFT 5 pmol/L. Cortisol is associated with serum inflammatory markers with similar trends observed for TT; conversely, the relationship between LH and inflammatory markers had different trends.
Opposite to men, in women with SARS-CoV-2 pneumonia, higher TT and cFT are associated with a stronger inflammatory status, probably related to adrenal cortex hyperactivity.
本研究旨在评估在呼吸重症监护病房(RICU)因 SARS-CoV-2 感染住院的女性患者队列中,睾丸激素(T)水平与生化标志物之间的关联。
对 17 名患有 SARS-CoV-2 肺炎并在曼图亚医院 RICU 康复的女性连续系列患者进行了分析。测定了生化炎症标志物以及总睾酮(TT)、计算游离 T(cFT)、性激素结合球蛋白(SHBG)和黄体生成素(LH)。
TT 和 cFT 与 PCT、CRP 和纤维蛋白原呈显著正相关,与更差的住院病程相关。我们没有观察到 TT 和 cFT 与 LH 之间存在任何显著关联;相反,TT 和 cFT 均与皮质醇呈正相关。通过 LOWESS 分析,可以假设 CRP 和纤维蛋白原之间存在线性关系,而 TT 与降钙素原、LDH 和铁蛋白之间的关系则存在阈值效应。当 TT 阈值为 1 nmol/L 时,TT 值高于此值时,TT 与 PCT、LDH 或铁蛋白之间存在显著关联。对于 LDH 和铁蛋白,在调整年龄后模型中也得到了证实。cFT 与炎症标志物的关联也存在类似的结果,即存在阈值效应,cFT 5 pmol/L 以上时,LDH 和铁蛋白水平升高与 LDH 和铁蛋白相关。皮质醇与血清炎症标志物相关,与 TT 观察到的趋势相似;相反,LH 与炎症标志物之间的关系则呈现出不同的趋势。
与男性不同,在患有 SARS-CoV-2 肺炎的女性中,较高的 TT 和 cFT 与更强的炎症状态相关,这可能与肾上腺皮质过度活跃有关。
