Abstract Background: Cortisol concentration is measured in blood, urine, and saliva samples. It has been recently proven that cortisol could be also detected in hair samples. Cortisol measurements in different samples have their own individual characteristics and clinical utility. We aimed to investigate the correlation between hair cortisol concentration and standard cortisol measurements used in clinical practice. Methods: Fifty adult volunteers with a negative history of endocrine disorders were enrolled into the study. Morning serum cortisol (MSC), evening serum cortisol (ESC), evening free salivary cortisol (EFSC), urine free cortisol (UFC) and hair cortisol were analyzed in all participants. Eventually, 41 volunteers were included into the study, whose cortisol concentration in the 1 mg overnight dexamethason suppression test (1mgONDST) were <50 nmol/l, and cortisol levels in serum, saliva and urine were within reference ranges. Hair cortisol concentration (HCC) was performed for 20 mg of hair strands of the proximal 1 cm hair segments. Results: HCC ranged from 0.3036 to 2.65 nmol/l/mg, and the average value was 0.8125±0.4834 nmol/l/mg. No significant correlations were found between HCC and MSC (rho=0.04419, p=0.7838), HCC and ESC (rho=-0.2071, p=0.1938), HCC and EFSC (rho=0.1005, p=0.532), and HCC and UFC (rho = 0.1793, p = 0.262). Conclusions : This work is another step in the discussion on the application of HCC determinations in clinical practice. Our results have showed no correlations between HCC and single point cortisol assessment in blood, saliva and urine in patients with reference cortisol levels.

Abstract Metabolic syndrome (MetS) is a highly prevalent disorder defined as a cluster of cardiometabolic risk factors including obesity, hyperglycemia, hypertension, and dyslipidemia. It is believed that excessive cortisol secretion due to psychosocial stress-induced hypothalamic-pituitary-adrenal axis activation might be involved in the pathogenesis of MetS. We sought to explore the association between MetS and psychosocial risk factors, as well as cortisol concentration measured in different biological specimens including saliva, blood serum, and hair samples. The study was conducted on a sample of 163 young and middle-aged men who were divided into groups according to the presence of MetS. Hair cortisol concentration (HCC) was determined using high performance liquid chromatography with UV detection, while blood serum and salivary cortisol levels were measured by enzyme-linked immunoassay. Lipid metabolism biomarkers were determined using routine laboratory methods. Anthropometric and lifestyle characteristics, as well as self-reported psychosocial indicators, were also examined. Significantly higher HCC and lower social support level among participants with MetS compared with individuals without MetS were found. However, no significant differences in blood serum and salivary cortisol levels were observed between men with and without MetS. In conclusion, chronically elevated cortisol concentration might be a potential contributing factor to the development of MetS.

Background Newborn premature infants are susceptible to development of relative adrenal insufficiency following transition from fetal to extrauterine life. However, the best diagnostic test for adrenal insufficiency in neonates has yet to be developed. Objectives and Methods The aim of this study was (1) to assess the feasibility of obtaining sufficient saliva sample to allow measurement of cortisol by liquid chromatography coupled to tandem mass spectrometry and (2) to assess the correlation, if any, between salivary and serum cortisol in preterm infants of ≤32 weeks' gestational age at birth. Results Samples for 230 paired serum and saliva cortisol levels from 90 preterm infants were analyzed. 87.5% of samples collected had sufficient salivary volumes for measurement. Despite being statistically significant (p < 0.0001), the correlation (Spearman r = 0.674) between serum and salivary cortisol was not strong. Conclusion Salivary free cortisol measurement is feasible but cannot be used to accurately reflect serum total cortisol. Further studies comparing salivary free cortisol to serum free cortisol and establishing normative data are needed before salivary cortisol can be used for diagnostic purposes.

Abstract Context: Subclinical Cushing’s syndrome has been described among diabetic populations in recent years, but no consensus has emerged about the value of screening. Methods: We enrolled 201 consecutive patients attending our diabetes clinic and 79 controls. Patients with at least two of the following three criteria were offered screening using a 2300 h salivary cortisol test: glycosylated hemoglobin of at least 7%, body mass index of at least 25 kg/m2, and a history of hypertension or blood pressure of at least 140/90 mm Hg. Results are expressed as mean ± sem. Results: Mean nighttime salivary cortisol levels were similar in the two groups (8.5 ± 1.0 nmol/liter for diabetic patients vs. 5.8 ± 1.0 nmol/liter for controls). Forty-seven patients (23%) had a value of at least 10 nmol/liter, which was set as a conservative threshold above which further investigation would be performed. Thirty-five (75%) agreed to further testing with a 1-mg overnight dexamethasone test. Of the remaining 12 patients, 10 were followed up clinically for at least 1 yr, and no evidence was found of the syndrome evolving. In 28 patients, serum cortisol suppressed to 60 nmol/liter or less. Of the seven patients who failed this test, four agreed to a 2 mg/d 48-h dexamethasone test, with serum cortisol suppressing to 60 nmol/liter or less in all four. Three declined this test but had normal 24-h urinary free cortisol levels. No patient had clinical features of hypercortisolism. Conclusions: The 1–3% detection rates of three recently published series have not been realized at our center where we studied a group using criteria making patients more likely to have hypercortisolism. Our results do not support the validity of screening patients without clinical features of Cushing’s syndrome in the diabetes clinic.

The aim of the study was to determine whether experience related to horse age and number of starts in championships influences stress level, measured by salivary cortisol concentration. The study involved 18 clinically healthy Hucul mares who participated in the Polish Championships for Hucul Horses. Evaluation of performance value was carried out in accordance with the guidelines specified in the breeding and genetic resources conservation program for this breed. The championship lasted two days, consisting of conformation evaluation, endurance, and Hucul path. Saliva was collected at baseline (T1), after arena assessment (T2), after endurance (T3), and on the second day after the Hucul path (T4). Cortisol levels increased from an average of 2.73 ± 1.18 ng/mL (T1) to 10.46 ± 8.03 ng/mL after T3. Significantly lower levels of free cortisol were detected in the saliva of the younger mares, up to 9 years old, and mares who participated in only one qualifying path after each element of the championship. The highest levels of cortisol (T3) were found in mares competing repeatedly on the qualifying path. No correlation was found between cortisol levels and the championship results. Participation of mares in the championship was associated with stress, which was reflected in the increase in cortisol levels in saliva.

Using levels of the stress hormone cortisol as an indicator for welfare is a common, but debated practice. In this observational study, hair cortisol concentration (HCC) of samples from 196 dairy calves from 7 to 302 days of age collected from 12 Swedish farms was determined using a commercially available ELISA. An assessment of animal welfare, assessed using animal-based indicators, was performed on the day of sampling. First, methodological factors with the potential to impact HCC and the effect of age were analyzed using generalized additive models. This revealed a significant peak in hair cortisol in young calves (around 50 days of age) and an association between fecal contamination of hair samples and the level of cortisol extracted. Second, associations between welfare indicators and HCC were explored using cluster analysis and regularized regression. The results show a complex pattern, possibly related to different coping styles of the calves, and indicators of poor welfare were associated with both increased and decreased hair cortisol levels. High cortisol levels were associated with potential indicators of competition, while low cortisol levels were associated with the signs of poor health or a poor environment. When running the regularized regression analysis without the contaminated hair samples and with the contaminated samples (including a contamination score), the results did not change, indicating that it may be possible to use a contamination score to correct for contamination.

The Relationship

AbstractSarcopenia, similar to hypercortisolism, is characterized by loss of muscle mass and strength. Cortisol circadian rhythm changes with aging (blunted late-day nadir values) were suggested to contribute to this decline. We aimed to explore the relationship between diurnal salivary cortisol values and sarcopenia diagnosis and its components in postmenopausal women. This is a cross-sectional study within the OsteoLaus population-based cohort in Lausanne (Switzerland). Participants had a body composition assessment by dual X-ray absorptiometry (DXA), a grip strength (GS) measure, and salivary cortisol measures (at awakening, 30 min thereafter, 11 AM (sc-11AM) and 8 PM (sc-8PM)). Associations between salivary cortisol and sarcopenia diagnosed by six different criteria (based on appendicular lean mass (ALM) assessed by DXA, and muscle strength by GS), and its components, were analyzed. 471 women aged > 50 years (63.0 ± 7.5) were included. Various definitions identified different participants as sarcopenic, who consistently presented higher salivary cortisol at 11 AM and/or 8 PM. There were no associations between salivary cortisol levels and ALM measures, either absolute or after correction to height squared (ALM index) or body mass index. GS was inversely correlated to sc-11AM (r = − 0.153, p < 0.001) and sc-8PM (r = − 0.118, p = 0.002). Each 10 nmol/l increase of sc-11AM, respectively sc-8PM, was associated with a GS decrease of 1.758 (SE 0.472) kg, respectively 2.929 (SE 1.115) kg. In postmenopausal women, sarcopenia is associated with higher salivary cortisol levels at 11 AM and 8 PM. An increase of daily free cortisol levels in the physiological range could participate to sarcopenia development by decreasing muscle function in postmenopausal women.

Cushing's disease (CD) is usually caused by secretion of ACTH by a pituitary corticotroph microadenoma. Nevertheless, 7%-20% of patients present with ACTH-secreting macroadenomas. Our aim is to report a 36-year-old female patient with CD due to solid-cystic ACTH-macroadenoma followed up during 34 months. The patient presented spontaneous remission due to presumed asymptomatic tumor apoplexy. She showed typical signs and symptoms of Cushing's syndrome (CS). Initial tests were consistent with ACTH-dependent CS: elevated urinary free cortisol, abnormal serum cortisol after low dose dexamethasone suppression test, and elevated midnight salivary cortisol, associated with high plasma ACTH levels. Pituitary magnetic resonance imaging (MRI) showed a sellar mass of 1.2 x 0.8 x 0.8 cm of diameter with supra-sellar extension leading to slight chiasmatic impingement, and showing hyperintensity on T2-weighted imaging, suggesting a cystic component. She had no visual impairment. After two months, while waiting for pituitary surgery, she presented spontaneous resolution of CS. Tests were consistent with remission of hypercortisolism: normal 24-h total urinary cortisol and normal midnight salivary cortisol. Pituitary MRI showed shrinkage of the tumor with disappearance of the chiasmatic compression. She has been free from the disease for 28 months (without hypercortisolism or hypopituitarism). The hormonal and imaging data suggested that silent apoplexy of pituitary tumor led to spontaneous remission of CS. However, recurrence of CS was described in cases following pituitary apoplexy. Therefore, careful long-term follow-up is required.

Salivary cortisol reflects the free fraction of serum cortisol. Monitoring salivary cortisol may be a promising alternative method for assessing serum cortisol in some clinical situations. We aimed to compare the reliability of salivary vs. serum cortisol during ACTH test. 84 subjects (mean age 63.2; 24-89 years; n=66 males) suspected for adrenocortical insufficiency underwent an ACTH test. Patients were divided based on peak serum cortisol into hypocortical group with cortisol <500 nmol/l and to reference group cortisol >500 nmol/l. Median serum cortisol levels in reference group were 445, 766, and 902 nmol/l at 0, 30, and 60 minutes, respectively, and in hypocortical group were 256, 394, and 453 nmol/l. Median salivary cortisol levels were 19.02, 40.02, and 62.1 nmol/l in reference group, and 9.60, 14.08, and 13.28 nmol/l in hypocortical group. Obtained values showed good correlation between serum and salivary cortisol (p<0.0001). The percentage of explained variability R2 (coefficient of determination for linear model) representing a measure of agreement between experimental values and predictions for repeated measures ANOVA, was significantly higher (p=0.021) for serum cortisol (R2=93.4 %) when compared to the salivary cortisol (R2=89.3 %). A stronger discriminating power of serum versus salivary cortisol suggests that it seems to be slightly, but statistically significantly more appropriate marker of adrenocortical reserve in ACTH test.

The Impact

Abstract Liver abscesses can affect cattle performance, though the impact on well-being is relatively unknown. The purpose of this study was to evaluate the relationship between liver abscess presence and stress-related parameters in feedlot cattle. Three hundred and sixty-three feedlot steers (675 ± 2.3 kg) that were enrolled in a nutrition feeding experiment were allocated to one of three groups based on the liver abscess score assigned after slaughter. The liver abscess scoring groups were: no liver abscess presence (NLA; n = 316); mild liver abscess presence (MLA; n = 21) and severe liver abscess presence (SLA; n = 24). Two animals were unable to be assigned liver abscess scores. Two days prior to slaughter, at the time of weighing, hair samples were collected from the right rump of each animal and analyzed for cortisol concentrations. Additionally, during restraint, infrared thermography was used to quantify eye temperatures and a mobility score was assigned to each animal upon chute exit. During slaughter, exsanguination blood was collected from 115 of the 363 animals and analyzed for serum cortisol concentrations. Cattle were blocked by nutrition feeding treatments and data were analyzed using analyses of variance to determine differences in outcome variables between liver abscess score groups. All animals were included in the infrared analysis and 115 animals were included in the serum and hair cortisol analyses. Infrared thermography (P = 0.55), hair cortisol (P = 0.96), and serum cortisol (P = 0.21) were similar across all liver abscess scores. All animals exhibited normal mobility, thus these values were not included in the analysis. The data indicate that under the conditions of this experiment, liver abscesses did not impact measured stress-related outcomes. Additional research is necessary to understand the impact of liver abscess presence on other stress-related parameters associated with well-being in cattle.
