Given Adrenal Symptoms, Blood Test Recommended

adrenal-glands

 

Q: My husband’s recent CT scan of his stomach and digestive system revealed that he has nodules on both adrenal glands. It was suggested that he undergo a blood test to determine whether the nodules are producing hormones.

For 21 months, he has experienced high blood pressure, nausea, diarrhea, anxiety and abdominal pain. Could this be the source of his problems? If so, what course of action would you recommend?

A: The adrenal gland is responsible for the production of several essential hormones.

Tumors, or nodules, of the adrenal glands are common. They can be categorized into those that make hormones and those that don’t, and also by whether the tumors are benign or malignant.

The most common, by far, are benign, nonfunctioning tumors. These are usually discovered on an ultrasound or a CT scan obtained for some other reason.

More than 4 percent of people have an adrenal mass, and 85 percent are nonfunctional.

The symptoms that your husband has, however, raise a concern that he might have a hormone-producing tumor.

Four types of hormones are commonly produced by adrenal tumors: cortisone, aldosterone, sex hormones (estrogen or androgens) and catecholamines (epinephrine and norepinephrine).

A cortisone-producing adrenal tumor causes Cushing’s syndrome. It usually causes weight gain, especially in the abdomen; skin changes, including striae, or “stretch marks”; high blood pressure; and a predisposition to diabetes. Anxiety and abdominal pain are uncommon.

Aldosterone raises blood pressure, so a person with a functioning adrenal tumor making aldosterone usually has high blood pressure, but the other symptoms you mention for your husband aren’t common for this type of tumor.

Adrenal tumors that make epinephrine and the related norepinephrine are called pheochromocytomas. Hypertension is almost universal with this condition, and anxiety is frequently reported.

Tumors that produce sex hormones are rare, and they are present in men with androgen excess or feminization, in the case of estrogen-secreting tumors.

Although your husband’s symptoms aren’t specific for any one condition, the combination of his symptoms and adrenal nodules concerns me.

I agree with the recommendation to look for excess amounts of hormones in the blood. This can often be achieved with a simple blood test; however, a catheter is occasionally placed in the adrenal vein to sample blood coming from the gland (and its nodule) directly.

By comparing one side against the other, doctors can determine which side might be producing excess hormones.

An endocrinologist is the expert most likely to be familiar with these conditions.

Lowest cortisol levels found in women with overweight, mild obesity

Women with overweight and class I obesity appear to have the lowest cortisol levels, while more significant obesity appears to be associated with higher cortisol levels, according to recent findings.

In the cross-sectional study, Karen K. Miller, MD, of Massachusetts General Hospital, and colleagues evaluated 60 premenopausal women aged 18 to 45 years: 28 with overweight or obesity, 18 with anorexia nervosa and 21 healthy controls at normal weight. Overweight was defined as BMI 25 to 29.9 kg/m2, and obesity was classified as class I (30-34.9 kg/m2) and class II (35-39 kg/m2).

Anorexia nervosa was classified based on DSM-IV criteria, which includes extreme fear of weight gain, body image dysmorphia, weight that is 85% of ideal body weight and cessation of menstruation for 3 consecutive months. Participants were asked to collect 24-hour urine samples, in addition to 11 p.m. and 7 a.m. salivary samples within 1 week of an inpatient hospital visit. For each sample, researchers assessed creatinine clearance, and urinary free cortisol/creatinine clearance was calculated for each specimen to account for the decreased creatinine and filtered cortisol linked to anorexia nervosa.

During the inpatient visit, participants underwent placement of an IV catheter and fasting blood was sampled every 20 minutes from 8 p.m. to 8 a.m. Fasting cortisol and cortisol binding globulin concentrations were measured at 8 a.m. Participants were asked to take 5 g of oral dexamethasone every 6 hours for 48 hours to decrease endogenous disparities in cortisol levels.

The researchers found that with the exception of dexamethasone-suppression-CRH testing, all cortisol measures exhibited a U-shaped association with BMI, most notably urinary free cortisol/creatinine clearance (P = .0004) and mean overnight serum cortisol (P < .0001).

The lowest cortisol levels were seen in the overweight-class I obesity range, and these were also associated with visceral fat tissue and total fat mass. Participants with anorexia nervosa had higher mean cortisol levels than participants with overweight or obesity. Attenuated inverse relationships were seen between lean mass and some measures of cortisol, and most measures of cortisol were inversely related to posterior-anterior spine and total hip bone mineral density.

According to the researchers, these findings have not determined the precise nature of the relationship between cortisolemia, hypothalamic-pituitary-adrenal activation and adiposity.

“The [hypothalamic-pituitary-adrenal] axis activation associated with obesity and excess adiposity raises the question of whether hypercortisolemia contributes to increased adiposity in the setting of caloric excess, whether increased adiposity drives [hypothalamic-pituitary adrenal] activation, or whether the relationship between hypercortisolemia and adiposity is bidirectional,” the researchers wrote. – by Jennifer Byrne

Food-dependent Cushing syndrome: a new entity of organic hypercorticism

Matejka G, et al. Rev Med Interne. 1996.

Abstract

Diagnosis of Cushing’s syndrome is quite difficult in endocrinology. Spontaneous Cushing’s syndrome is usually divided into two subgroups, one which is dependent on corticotropin (ACTH) and another one which is not.

In the first class are Cushing’s disease, the ectopic corticotropin syndrome and the rare ectopic corticotropin-releasing hormone (CRH) syndrome; these ACTH-dependent Cushing’s syndrome have usually diffusely enlarged adrenal glands.

In the second class are cortisol producing unilateral adrenocortical adenomas or carcinomas, and the recent Cushing’s syndrome with food dependent periodic hormonogenesis.

This food dependent Cushing’s syndrome is an ACTH-independent Cushing’s syndrome with multinodular enlargement of both adrenal glands. Pathogenesis is an aberrant adrenal sensitivity to physiologic secretion of gastric inhibitory peptide (GIP). Ectopic expression of GIP receptors on adrenal cells involve pathologic food induced cortisol secretion.

Food dependent Cushing’s syndrome is a new cause of Cushing’s syndrome. Food induced cortisol secretion may have to be explored in the ACTH-independent Cushing’s syndrome.
