Urinary excretion of cortisol, norepinephrine, testosterone, and melatonin in panic disorder
Abstract
Nocturnal urinary cortisol, norepinephrine, epinephrine, testosterone, and melatonin secretion patterns were studied in male patients with DSM IV/ICD-10 panic disorder (n = 16) over two series of 5 consecutive nights each. Night-time urinary excretion of cortisol, norepinephrine, and epinephrine was significantly elevated in drug-free patients compared to normal individuals (n = 13). Measurements were repeated after 4 weeks, and the same differences were found again. There were high correlations between the first and the second series of measurements. Testosterone and melatonin levels did not differ between panic patients and controls.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 16 participants or records.
