Serum zinc levels have been measured in twenty-four asthmatic patients, of whom sixteen were on long term corticosteroid therapy. They were carefully screened to exclude any concomitant disease. The non-steroid-treated asthmatics had normal serum zinc levels which ranged from 89 to 138 μg/ml. The corticosteroid-treated patients had a mean serum zinc level of 64 ± 9 μg/100 ml; this was significantly lower than normal (P = < 0·001).
Abstract The implications of essential trace elements in endocrinological processes, mainly thyroid function, growth, gonadal function, adrenal hormones, prolactin, glucose homeostasis, calcium-phosphorus metabolism, and thymulin activity, are reviewed. Most concerned elements in this field include iodine, zinc, selenium, copper, chromium, manganese and vanadium. The minerals are powerful modulators of several physiological functions that can be considerably perturbed in deficiency states. The resulting biochemical and clinical modifications can be prevented and/or corrected by adequate supplementation. Sometimes, however, they act like pharmacological agents when their beneficial effects are not the result of a correction of a nutritional deficiency state. Their potentialities as therapeutic agents are perfectly described in many cases, but some indications deserve further investigations.

Zinc acutely and temporarily inhibits adrenal cortisol secretion in humans. A preliminary report.Brandão-Neto J, de Mendonça BB, Shuhama T, Marchini JS, Pimenta WP, Tornero MT.
Hypo- and hyperzincemia has been reported to cause alterations in the adrenal secretion. To determine the acute effect of zinc on cortisol levels, we studied 27 normal individuals of both sexes aged 20-27 y after a 12-h fast. The tests were initiated at 7:00 AM when an antecubital vein was punctured and a device for infusion was installed and maintained with physiological saline. Zinc was administered orally at 8:00 AM. Subjects were divided into an experimental group of 13 individuals who received doses of 25, 37.5, and 50 mg of zinc and a control group of 14 individual who received 20 mL of physiological saline. Serial blood samples were collected over a period of 240 min after basal samples (-30 and 0 min). We detected an acute inhibitory effect of zinc on cortisol secretion during 240 min of the study period in the experimental group.
I am waiting Jimmy from you to mention zinc-adrenal gland connection but you don't and surprise me!
Zinc affects remarkably adrenal function and is the most helpfull mineral for them (iodine, selenium also).

Thanks everyone for your input, if we weren't our own advocates and teachers we'd be up the creek.

dim, that's great that you noticed an improvement in your wife's pigmentation problem too!
