Advances in immunology, biochemistry, and molecular biology have combined to allow the development of a large series of autoantibody assays utilizing recombinantly produced autoantigens. Labeled target proteins can be readily produced by in vitro transcription and translation of relevant cloned cDNA. The assays are carried out in the fluid phase and for most assays are more specific and sensitive than ELISA based assays. For some antigens (e.g. insulin) though ELISA assays detect antibodies following immunization, workshops indicate they are almost worthless for the diagnosis and prediction of type 1A diabetes. This new generation of radioassays is usually carried out in 96-well microtiter filtration plates that allow high throughput. Given such assays, individuals at high risk for type 1A diabetes, celiac disease, and Addison's disease can now be readily identified.
Two hundred and twenty-five subjects, including normal volunteers and patients with previously documented seasonal affective disorder (SAD), chronic fatigue syndrome (CFS), Cushing's syndrome, Addison's disease and obsessive-compulsive disorder (OCD), completed a self-rated inventory of reported sensitivity to various chemical exposures. Patients with CFS, Addison's disease and SAD self-reported more sensitivity to chemical exposures than normal controls. In addition, women reported more sensitivity than men. This report suggests that chemical sensitivity may be a relevant area to explore in certain medical and psychiatric populations. A possible relationship between reported chemical sensitivity and hypothalamic-pituitary-adrenal (HPA)-axis functioning is discussed.
We present a case of high-turnover osteoporosis associated with substituted adrenocortical insufficiency (Addison's disease) and its successful treatment with calcitonin and calcitriol. A 43-year-old man presented with markedly reduced bone mineral density (BMD) (lumbar spine BMD -3.46 SD below healthy young adults) after thirteen years of glucocorticoid substitution. Interestingly, his osteocalcin levels indicated an unusually high bone turnover and his alkaline phosphatase levels were also increased. Combination treatment with calcitriol and calcitonin was started. Re-evaluation after twelve months revealed a substantial increase in BMD (+6.8% for the lumbar spine, +15% for the left hip). Alkaline phosphatase levels had normalised and osteocalcin was nearly down to normal. In spite of a thorough evaluation, no other cause of osteoporosis was detected. We discuss these findings in view of the existing literature.
