SynopsisCerebrospinal fluid (CSF) cortisol levels were examined in a total group of 65 patients. Those who were not depressed (ND), and those suffering from depressive neuroses (DN) had marginally elevated values. Patients with unipolar depression (UD) and bipolar depression (BD) had levels twice as high as the ND and DN patients. Psychotic UD and BD patients had the highest values, three to four times as high as the ND and DN subjects. A significant reduction of CSF cortisol levels was observed following treatment and recovery. Manic patients had moderately elevated CSF cortisol values. The CSF results were in good agreement with plasma total cortisol levels and with urinary free cortisol excretion. Age and sex effects were not responsible for the observed differences; similar results were found in patient subgroups studied in Australia and in the United States. Preliminary equilibrium dialysis data are presented for plasma and CSF cortisol binding. CSF cortisol was 20% bound and 80% free. Plasma free cortisol levels were in good agreement with CSF free cortisol values. Depressed patients have increased tissue and central nervous system (CNS) exposure to free, physiologically active glucocorticoids. The appearance of severe depressive symptoms which manifest a diurnal rhythm may be determined in part by excessive CNS exposure to glucocorticoids.

OBJECTIVE: Muscular exercise induces hypothalamo-pituitary-adrenal (HPA) axis activation and when regularly repeated, as in endurance training, leads to HPA axis adaptation. To assess whether non-professional endurance-trained (ET) men with a substantial training load and no clinical or biological features of HPA axis overactivity can present subtle alterations of HPA axis sensitivity to glucocorticoid negative feedback, nine ET men were subjected to HPA axis testing using the dexamethasone-corticotrophin-releasing hormone (CRH) test. DESIGN: Nine endurance-trained men and eight healthy age-matched sedentary men were studied. Morning plasma cortisol and 24 h urinary free cortisol (UFC) were determined and a low dose dexamethasone suppression test (LDDST) was performed followed by CRH stimulation (dexamethasone-CRH test). RESULTS: After a day without physical exercise, at 0800 h, plasma ACTH and cortisol concentrations, and the 24 h UFC and UFC/urinary creatinine (UC) ratio were similar in ET and sedentary men. By contrast, clear differences between the groups were seen in cortisol and ACTH responses to the dexamethasone-CRH test. In eight ET subjects, after LDDST, basal ACTH and cortisol levels were similar to those of sedentary men, whereas one ET subject displayed a poor suppression of cortisol level (131 nmol/l). After injection of CRH, however, three of nine ET men's cortisol levels were not suppressed by dexamethasone but instead displayed significant CRH-induced increase (peak cortisol: 88, 125 and 362 nmol/l). No sedentary subject exhibited any increase in cortisol levels. CONCLUSION: Three of nine ET men with a mean maximum rate of O2 uptake (VO2, max) of 61 ml/kg per min, running 50-70 km per week, were resistant to glucocorticoid suppression during the combined dexamethasone-CRH test.

Recent data indicate that bipolar illness is underdiagnosed and therefore undertreated in the community (Slide 1). A recent survey of >85,000 households in the United States found a 3.7% positive screen for prominent bipolar symptomatology. Using the Mood Disorder Questionnaire, which has good specificity and sensitivity in outpatient clinics, the study also found that the prevalence was higher, 9.3%, among patients 18–24 years of age. However, most disappointing was that only 20% of the positive screens were diagnosed as bipolar, and among those, most were not treated with mood stabilizers. In addition, 31% of patients had been diagnosed with unipolar depression. Several studies have shown that approximately 20% to 40% of presumptively unipolar patients actually have bipolar II or bipolar disorder not otherwise specified. Combined, the data show that bipolar disorder, bipolar depression in particular, is highly prevalent and often misdiagnosed or unrecognized.Two recent studies found virtually the same data showing that depression is the predominant problem in naturalistically treated bipolar outpatients. Judd and colleagues found that depression was three times more prevalent than mania in bipolar patients. This is exactly what was found in the Stanley Foundation bipolar outpatient follow-up study, which rated the study's first 258 patients every day for 1 year (Slide 2). The study found that patients were ill almost 50% of the time; they were depressed 33% of the days in the year, and hypomanic or manic 10.8% of the days. This occurred despite aggressive treatment with a variety of agents, such as mood stabilizers, antidepressants, and benzodiazepines in 50% of the patients, and typical or atypical neuroleptics in almost 50% of the patients. Thus, even bipolar patients who are intensively treated in academic settings have a very substantial degree of morbidity, particularly depression.

ObjectiveThe possible different prevalence of arterial hypertension (AH), type 2 diabetes mellitus (T2DM), dyslipidaemia (DL) and vertebral fractures (FX) between patients with bilateral and unilateral adrenal incidentalomas (BAI and UAI, respectively) with and without subclinical hypercortisolism (SH) is unknown. In this study we compared the prevalence of AH, T2DM, DL and FX in BAI and UAI patients in relation to SH.DesignProspective study.MethodsIn 175 UAI and 38 BAI patients, we evaluated BMI, spinal and femoral bone mineral density (LS and FN BMD, respectively) and the presence of AH, T2DM, DL and FX. SH was diagnosed in the presence of ≥2 of the following: urinary free cortisol levels >193 nmol/24 h, serum cortisol levels after 1 mg dexamethasone suppression test >83 nmol/l or ACTH levels <2.2 pmol/l.ResultsAge, BMI and cortisol secretion were comparable, while FN BMD was lower in BAI than in UAI patients (−0.45±0.86 vs 0.09±1.07, P=0.004). The prevalence of SH, AH, T2DM, and DL was comparable, while the prevalence of FX was higher in BAI than in UAI (52.6 vs 28%, P=0.007). The presence of FX was associated with BAI (odds ratio (OR) 2.6, 95% confidence interval (95% CI) 1.2–5.6, P=0.016), after adjusting for SH (OR 1.77, 95% CI 0.85–3.7, P=0.12), BMI (OR 1.06, 95% CI 0.98–1.13, P=0.1), age (OR 1.07, 95% CI 1.04–1.11, P=0.0001) and LS BMD (OR 1.31, 95% CI 1.03–1.67, P=0.03).ConclusionBAI patients have an increased FX risk than UAI ones. Further studies should investigate the causes of bone involvement in BAI patients.

AbstractHigh Na intake and chronically elevated cortisol levels are independently associated with the development of chronic diseases. In adults, high Na intake is associated with high levels of urinary cortisol. We aimed to determine the association between urinary Na and K and urinary cortisol in a cross-sectional sample of Australian schoolchildren and their mothers. Participants were a sample of Australian children (n 120) and their mothers (n 100) recruited through primary schools. We assessed Na, K, free cortisol and cortisol metabolites in one 24 h urine collection. Associations between 24 h urinary electrolytes and 24 h urinary cortisol were assessed using multilevel mixed-effects linear regression models. In children, urinary Na was positively associated with urinary free cortisol (β=0·31, 95 % CI 0·19, 0·44) and urinary cortisol metabolites (β=0·006, 95 % CI 0·002, 0·010). Positive associations were also observed between urinary K and urinary free cortisol (β=0·65, 95 % CI 0·23, 1·07) and urinary cortisol metabolites (β=0·02, 95 % CI 0·03, 0·031). In mothers, urinary Na was positively associated with urinary free cortisol (β=0·23, 95 % CI 0·01, 0·50) and urinary cortisol metabolites (β=0·008, 95 % CI 0·0007, 0·016). Our findings show that daily Na and K intake were positively associated with cortisol production in children and their mothers. Investigation of the mechanisms involved and the potential impact of Na reduction on cortisol levels in these populations is warranted.
