| Abstract |
Impaired cortisol rhythm is a characteristic feature of Cushing's Syndrome, nevertheless late night salivary cortisol (LNSC) is not suitable to detect subclinical hypercortisolism in patients with adrenal incidentaloma (AI). We studied daily salivary cortisol (F) and cortisone (E) rhythm in patients with AI. Six saliva samples were collected from awakening to night in 106 patients with AI and 40 controls. F and E were measured with LC-MS/MS and daily F exposure was calculated with the area under the curve (AUC). Patients with serum cortisol after dexamethasone suppression test (DST) > 50 nmol/L showed higher morning F (15.5 ± 14.5 vs. 8.6 ± 5.5 nmol/L, p = 0.001), suppressed corticotropin levels (76 vs. 35%, p < 0.001) and increased daily F exposure (3795 ± 1716 vs. 2898 ± 1478, p = 0.012), especially in the morning (2035 ± 1267 vs. 1365 ± 777, p = 0.003), otherwise LNSC levels were similar. Salivary E and AUC levels were higher in patients with DST > 50 nmol/L. AUC was not correlated with urinary cortisol levels or adenoma size. F and E levels were similar among patients with unilateral or bilateral adenoma, or considering the presence of hypertension, dyslipidemia, diabetes, or cardiovascular events. Daily cortisol exposure, evaluated with AUC from multiple saliva collections, is increased in AI patients with serum cortisol > 50 nmol/L after DST, especially in the morning, leading to reduced corticotropin levels. Cortisol rhythm is preserved in patients with AI, remarking that LNSC is not a screening test for subclinical hypercortisolism. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 October 2017.
All research outputs
#18,573,839
of 23,005,189 outputs
Outputs from Endocrine
#1,177
of 1,701 outputs
Outputs of similar age
#245,821
of 320,773 outputs
Outputs of similar age from Endocrine
#26
of 41 outputs
Altmetric has tracked 23,005,189 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,701 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one is in the 18th percentile – i.e., 18% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 320,773 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 41 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
