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.

Cirrhotic Patients

Relative adrenal insufficiency (RAI) was demonstrated in patients with cirrhosis and liver failure. A relationship appears to exist between the severity of the liver disease and the presence of RAI. Neither the mechanism nor the exact prevalence of RAI is fully understood. There is though a hypothesis that low high-density lipoprotein (HDL) levels in this group of patients may be responsible for the insufficiency of cortisol. Several questions also arise about the way and the kind of cortisol (total cortisol, free cortisol, or even salivary cortisol) that should be measured. The presence of RAI in patients with cirrhosis is unquestionable, but still several studies should come up in order to properly define it and fully understand it.

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.

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 Introduction: About 20–40% of patients with Cushing’s syndrome present with cyclic Cushing’s Syndrome characterized by episodes of cortisol excess interspersed with periods of normal cortisol secretion. A high degree of suspicion is needed to identify patients with cyclical hypercortisolism. Fluctuations in cortisol levels can make this a diagnostic challenge. Rarely, hypocortisolemia and frank adrenal insufficiency can occur. Case Report: A 77-year-old female with history of Cushing’s syndrome and transsphenoidal surgery with no adenoma identified on pathology presented with fatigue and concern for recurrence with ACTH of 358 pg/mL (6–50 pg/mL) and morning serum cortisol of 41.4 mcg/dL. Brain MRI showed a possible 4 mm pituitary adenoma. However, when she was transferred to our hospital, there was no evidence of hypercortisolism with cortisol of 9.5 mcg/dL, ACTH of 33pg/mL, 24 hr urine free cortisol (UFC) of 4.4ug/d (&lt;45ug/d) and she was discharged home after neurosurgery recommended no surgical intervention. A week later, the patient returned to the hospital with nausea and weakness, and found to have cortisol of 4.4mcg/dL, ACTH of 12 pg/mL and UFC of 2.8 ug/d requiring short course of hydrocortisone for adrenal insufficiency. One year later, she presented with hip fracture, worsening weakness, plethora, and facial swelling. UFC was 1,338.3mcg/24 hr(4.0–50.0 mcg/24 hr), AM serum cortisol 58.8mcg/dL and ACTH 304.7 pg/mL. In addition to severe osteoporosis with hip fracture, she had hypertension and impaired fasting glucose. She was treated with Ketoconazole 200mg daily which was titrated until AM cortisol levels decreased from 58.8 mcg/dL to 20 mcg/dL. Patient was discharged on Ketoconazole with plan to complete a Dotatate scan to evaluate for ectopic ACTH production which resulted negative. Shortly thereafter, she returned with hypotension, nausea, and fatigue. Repeat cortisol level was 2.3 mcg/dL with ACTH of 27.6 pg/ml. Ketoconazole was discontinued and patient was started on hydrocortisone for adrenal insufficiency. Hydrocortisone was gradually tapered off. Pituitary MRI and IPSS are planned for further evaluation. Discussion: Cyclic Cushing’s syndrome is diagnosed with three peaks and two troughs of cortisol production. Diagnosis and treatment are challenging since the cycles of hypercortisolism can occur sporadically and rapid fluctuations in cortisol makes it difficult to localize a source. Cortisol fluctuations can affect quality of life and result in complications such as diabetes, hypertension, and osteoporosis. Prompt identification of the source of the Cyclic Cushing’s syndrome is vital to pursue definitive therapy. However, in 9% of cases, there is no identifiable source. In such cases, medical therapy is warranted.

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.

This study was designed to correlate entertainment of clown-doctors (CD) activities on hospitalized children and aphysiological biomarker. For this purpose we collected saliva samples and verified children satisfaction with these activities by using a visual analog scale (VAS). Children from 6 to 7 years-old, with diagnosis of any acute pathology, interned in the Pediatric Ward of the Botucatu Medical School Hospital (São Paulo, Brazil) were interviewed. Two groups were taken into consideration: lunchCD and dinnerCD. The following protocol was applied in each group (lunch and dinner): collection of the first saliva sample and presentation of VAS prior to CD activities, followed by collection of a second saliva sample and another VAS assessment after CD activities. The salivary cortisol was reduced in both groups comparing the first saliva sample. The satisfaction of the intervention was evident for lunchCD. The CD intervention is effective in decreasing an important physiological biomarker of stress factor, cortisol, in hospitalized children, been effective for the healing process.
