The relationship of adrenal iodomethylnorcholesterol uptake to indices of adrenal cortical function in Cushing's syndrome.

The adrenal gland uptake of 131I-6-beta-iodomethyl-19-norcholesterol (NP-59) was calculated using a semioperator-independent computer algorithm in 17 patients with Cushing's syndrome (CS). Twelve had ACTH-dependent and 5 had ACTH-independent CS. The mean adrenal gland uptake (percentage of administered dose) of NP-59 was 0.74 +/- 0.18% (range, 0.21-2.02%) in CS and was significantly higher than that of normal subjects (0.33 +/- 0.02%). Patients with the ectopic ACTH syndrome and ACTH-independent CS manifested the highest uptakes (mean, 1.18 +/- 0.08%; range, 0.74-2.02%). In the patients with ACTH-dependent CS, a significant correlation was observed between 24-h urinary free cortisol excretion and NP-59 adrenal gland uptake (r = 0.97, P less than 0.001). No relationship was seen between NP-59 uptake and urinary free cortisol in ACTH-independent CS or between NP-59 uptake and urinary 17-hydroxycorticosteroids, 17-ketosteroids, cortisol secretion rate, plasma cortisol, or ACTH levels in either ACTH-dependent or ACTH-independent CS. We conclude that in addition to localizing the sites(s) of adrenocortical hypersecretion in CS, the level of NP-59 adrenal uptake is a reflection of cortisol excretion in ACTH-dependent disease and may be utilized as another parameter to quantitate adrenal disease activity in CS.

Alternate day prednisone therapy in congenital adrenal hyperplasia: adrenal androgen suppression and normal growth.

Daily glucocorticoid therapy of children with congenital adrenal hyperplasia (CAH) frequently results in a suboptimal mature height. In contrast, pharmacological doses of prednisone given on alternate days generally allow normal growth in children with autoimmune, hematological, and renal disorders. Moreover, alternate day prednisone therapy suppresses adrenal androgen secretion on both the day on and the day off therapy in patients with systemic lupus erythematosus. We hypothesized that alternate day prednisone therapy might be efficacious in the treatment of CAH. To evaluate this hypothesis, we studied an 11-yr-old girl with salt-losing 21-hydroxylase deficiency and severe asthma treated with alternate day prednisone therapy (20 mg every other day) for over 3 yr. During this period her linear growth was along the 65th percentile, and her bone age paralleled her chronological age. Pubertal development was normal, and she had no signs of androgen or glucocorticoid excess. In keeping with her clinical picture, basal (24-h samples drawn every 60 min) and ovine CRH-stimulated plasma adrenal androgen (dehydroepiandrosterone sulfate and delta 4-androstenedione) concentrations and 24-h urinary 17-ketosteroid excretion were low on both the day on and the day off prednisone. However, her plasma ACTH and 17-hydroxyprogesterone levels were markedly elevated on both days. The adrenal androgen suppression, therefore, appeared independent of the level of ACTH, suggesting different regulation of the zona fasciculata and the zona reticularis. GH secretion, assessed by measurement of plasma GH every 20 min for 48 h, was normal on both the on and off days of prednisone therapy. Therefore, in this girl pharmacological doses of prednisone given on alternate days caused sustained adrenal androgen suppression and allowed normal growth and pubertal development, despite persistently elevated plasma ACTH and 17-hydroxyprogesterone levels.

Abnormalities of 21-hydroxylase gene ratio and adrenal steroidogenesis in hyperandrogenic women with an exaggerated 17-hydroxyprogesterone response to acute adrenal stimulation.

One to 2% of hyperandrogenic women demonstrate a 17-hydroxyprogesterone (17-HP) level greater than 36.3 nmol/L (1200 ng/dL) after acute ACTH-(1-24) adrenal stimulation, consistent with 21-hydroxylase (21-OH) deficient late-onset adrenal hyperplasia (LOAH). The following study was undertaken to endocrinologically and genetically define hyperandrogenic patients with an exaggerated 17-HP response to ACTH stimulation, and which do not represent LOAH. Of 265 consecutive patients suffering from hirsutism and/or hyperandrogenic oligomenorrhea, 23 (8.7%) demonstrated a 17-HP level 30 min post stimulation greater than 9.6 nmol/L or 316 ng/dL (the upper 95th percentile in 41 eumenorrheic nonhirsute healthy control women). Seven patients or five separate families (1.8% of total) demonstrated poststimulation 17-HP levels consistent with LOAH. Of the remaining 16 patients, the net increment in 17-HP (delta 17-HP0-30) was within normal limits in seven (2.6%) and these women were assumed to have a normal 17-HP adrenocortical response superimposed on an elevated basal level of nonadrenal (e.g. ovarian) origin. In the remaining nine hyperandrogenic patients (3.4%) various abnormalities of adrenal response were noted in all but one patient, consistent with adrenal hyper-responsiveness. One patient demonstrated an 11-deoxycortisol poststimulation level greater than 3-fold the upper 95th percentile of normal, consistent with 11-hydroxylase LOAH and was excluded from further study. Six of these women were available for further genetic characterization, all Caucasian and unrelated. Three were heterozygotes for HLA-B14, three for B40, and one for B35 antigen, HLA-types associated with the inheritance of 21-OH deficiencies. Although, normally there are two 21-OH genes (a pseudogene and a functional gene) present in a 1:1 ratio, we have previously reported a high frequency of 21-OH gene ratio abnormalities in LOAH. All but one of our patients demonstrated an abnormal 21-OH gene ratio. In conclusion, 3.4% of our hyperandrogenic population demonstrated an exaggerated 17-HP increment after ACTH stimulation, not consistent with LOAH or increased extraadrenal 17-HP production. The increased prevalence of HLA alleles known to be linked to inherited defects of 21-OH function and the increased frequency in 21-OH gene ratio abnormalities suggest that a majority of these individuals may be carriers for these genetic disorders. However, the adrenocortical abnormalities noted were more consistent with a generalized hyperreactivity of the adrenal to ACTH stimulation, than a specific enzyme deficiency, implying that carrier status for 21-OH deficiency may be incidental to the hyperandrogenism.

Congenital adrenal hyperplasia presenting as massive adrenal incidentalomas in the sixth decade of life: report of two patients with 21-hydroxylase deficiency.

Divergent recommendations exist regarding the evaluation of adrenal incidentalomas. Recent data have indicated a prevalence of adrenal tumors of 71% in nonclassical congenital adrenal hyperplasia (CAH) and unmasked heterozygotes. These data expand the differential diagnosis of such incidental tumors and substantially modify the approach to their evaluation. We present two patients, female pseudohermaphrodites with the simple virilizing form of CAH and 21-hydroxylase deficiency, who functioned successfully as married phenotypic males. Both came to medical attention in the sixth decade by virtue of massive adrenal incidentalomas encountered in the evaluation of recurrent urinary tract infections. Each had a 46, XX karyotype, no palpable testes, and markedly elevated baseline levels of 17-hydroxyprogesterone (17-OH Prog) of 6086 ng/dL and 6750 ng/dL. Both responded appropriately to dexamethasone suppression with reduction of 17-OH Prog, androgens and, in the second patient, ACTH to normal or near normal levels. Histologic and autopsy examination of the first patient's tumor and computed tomographic characteristics of the second revealed a benign adenoma and myelolipoma respectively. We extend and confirm previous recommendations that CAH be included in the differential diagnosis of adrenal incidentaloma and that baseline 17-OH Prog. levels be obtained, with ACTH stimulation if necessary, to diagnose the presence of nonclassical CAH.

High prevalence of testicular adrenal rest tumors, impaired spermatogenesis, and Leydig cell failure in adolescent and adult males with congenital adrenal hyperplasia.

In male patients with congenital adrenal hyperplasia, testicular tumors, or so-called adrenal rest tumors, have been described, but their presence in well controlled patients is thought to be rare. In this study, the prevalence of testicular tumors in 17 adolescent and adult male patients with congenital adrenal hyperplasia (age, 16-40 yr) was investigated. In 16 of 17 patients, one or more testicular tumors, ranging in maximal length from 0.2-4.0 cm, were found on ultrasonography. In 6 patients, the testicular tumors were palpable. Undertreatment, defined as the presence of a salivary androstenedione level (mean of 6 saliva samples collected over 24 h with intervals of 4 h) above the upper reference morning level, was found in 5 of 17 patients at the time of investigation. The other 12 patients were treated adequately or even over treated at the time of investigation. Nevertheless, 11 of these 12 patients showed testicular tumors on ultrasonography. Neither the presence of undertreatment at the time of investigation nor characteristics of the therapeutic regimen (daily dose of hydrocortisone equivalents per body surface, the use of glucocorticoid medication either two or three times a day, or the time of taking the highest glucocorticoid dose either in the morning or the evening) could predict tumor size (maximal diameter of largest tumor). In patients who were heterozygous or homozygous for the deletion or conversion of the CYP21 gene, tumor size was significantly larger than in patients who did not have this genotype. Impairment of Leydig cell function as manifested by decreased plasma levels of T was found in 6 of 17 patients. Semen analysis in 11 patients revealed azoospermia in 3 patients and poor semen quality in 4 patients. We conclude that, when carefully sought for, testicular adrenal rest tumors are frequently present in adolescent and adult males with congenital adrenal hyperplasia and are often accompanied by impaired spermatogenesis and Leydig cell failure.

A case of ACTH-independent macronodular adrenal hyperplasia: simultaneous expression of several aberrant hormone receptors in the adrenal gland.

ACTH-independent macronodular adrenal hyperplasia (AIMAH) is a rare cause of Cushing's syndrome. Recently, aberrant expression of adrenal receptors for various hormones and/or cytokines has been identified in several cases with AIMAH, which may act as a pathogenetic factor for the disorder. We report here an AIMAH patient with a Rathke's cleft cyst. Endocrinological examinations revealed that the pituitary cyst had no hormonal secretion. Administrations of either AVP or isoproterenol provoked cortisol production in the patient, whereas DDAVP, mosapride or endogenous LH induced by GnRH did not. Reverse transcriptional-PCR analysis of total RNA obtained from the patient's adrenal tissue revealed the expression of mRNA of receptors for V1a, V1b, V2, and LH/hCG. Three of these receptors except for V1a receptor were not expressed in normal adrenal tissue. Hyperosmolar saline infusion promoted the patient's cortisol secretion through the increase in endogenous AVP (peak plasma AVP level reached 90.4 pg/ml during the test). These results suggest that endogenous AVP and catecholamines are involved in the pathophysiology of the patient. Further study will be necessary to clarify the molecular mechanisms that regulate tissue-specific expression of these receptors and their role in the overgrowth of adrenal in AIMAH.

Adrenal nodules in patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency: regression after adequate hormonal control.

Adrenal nodules have been described in patients with 21-hydroxylase deficiency (21OHD). These nodules are usually considered to be ACTH-dependent, as is the commonly seen diffuse cortical hyperplasia. We evaluated the presence and behavior of adrenal nodules in patients with 21OHD. Based upon hormonal status and treatment compliance, the patients were classified into three categories: poor, regular and good control. Out of the 26 patients, eight had the non-classic, four salt-wasting and 14 simple virilizing forms. All patients underwent initial adrenal morphological studies, either by CT or MRI. Those with nodules were reevaluated after 12 months of adequate replacement therapy. Nodules were found in four of eight untreated patients and two of three patients with poor hormonal control, but not in the 15 patients with regular or good control. Adrenal nodules in these six patients demonstrated a considerable size reduction and even disappearance after adequate replacement therapy, showing that these nodules were ACTH-dependent. Thus, six out of 26 patients with 21OHD presented adrenal nodules, which were more frequent in the untreated or poorly-controlled patients, and all regressed in size after adequate therapy.

Familial adrenocorticotropin-independent macronodular adrenal hyperplasia with aberrant serotonin and vasopressin adrenal receptors.

ACTH-independent macronodular adrenocortical hyperplasia (AIMAH) is rare and generally presents as a sporadic disease. We describe a familial case of AIMAH with in vivo and in vitro demonstration of aberrant 5-HT4 and vasopressin adrenal receptors. Two sisters presented with clinical and biological features of mild Cushing's syndrome with bilateral macronodular adrenal enlargement on computerized tomography (CT)-scan evaluation. In vivo pharmacological tests showed a significant increase in plasma cortisol after terlipressin and metoclopramide administration. Unilateral adrenalectomy was performed in one of these patients. Reverse transcriptase-PCR analysis of the hyperplastic tissue revealed expression of 5-HT4 receptor isoforms (a), (b), (c), (i), and (n), and of vasopressin receptors, V1 and V2. Their father and brother were overweight, had easy bruisability and presented with biological features of subclinical Cushing's syndrome. CT scan showed moderate adrenal enlargement. In vivo pharmacological screening tests for the detection of adrenal aberrant receptors in the brother were negative. Finally, three out of the two sisters' children were evaluated. They had neither clinical nor biological features of Cushing's syndrome. Their adrenal glands were normal on CT-scan evaluation. In vivo evaluation for the detection of aberrant adrenocortical receptors performed in one of these subjects was negative. In conclusion, this study shows that (i) familial AIMAH could be an autosomal dominantly inherited disorder; (ii) aberrant 5-HT4 serotonin and vasopressin receptors can be expressed in familial AIMAH; and (iii) phenotypic expression of familial AIMAH could be varied in a same family and more pronounced in female than in male patients.

Cerebellin and cerebellin mRNA in the human brain, adrenal glands and the tumour tissues of adrenal tumour, ganglioneuroblastoma and neuroblastoma.

The expression of cerebellin and cerebellin mRNA was studied by radioimmunoassay and Northern blot analysis in the human brain, adrenal gland and the tumour tissues of adrenal tumour, ganglioneuroblastoma and neuroblastoma. Immunoreactive cerebellin was detected in every region of brain studied, with the highest concentrations found in the hemisphere of the cerebellum (424.2 +/- 12.6 pmol/g wet weight, n = 6, mean +/- S.E.M.) and the vermis of the cerebellum (256.8 +/- 30.5 pmol/g wet weight). Immunoreactive cerebellin was also detected in the pituitary (8.2 +/- 1.8 pmol/g wet weight), the spinal cord (3.3 +/- 0.3 pmol/g wet weight) and the normal parts of adrenal glands (2.98 +/- 0.37 pmol/g wet weight, n = 9) and some tumour tissues, such as phaeochromocytomas, cortisol-producing adrenocortical adenomas, ganglioneuroblastomas and neuroblastomas. Northern blot analysis showed that cerebellin mRNA was highly expressed in the hemisphere and vermis of the cerebellum. Cerebellin mRNA was also expressed in other regions of the brain and the tumour tissues of phaeochromocytoma, cortisol-producing adrenocortical adenoma, ganglioneuroblastoma and neuroblastoma. Immunocytochemistry of the normal adrenal gland showed that immunoreactive cerebellin was localized in the adrenal medulla. The present study has shown the expression of cerebellin and cerebellin mRNA, not only in the cerebellum but also in other regions of the brain and some tumours, such as cortisol-producing adrenocortical adenoma, phaeochromocytoma and neuroblastoma. These findings suggest possible pathophysiological roles of cerebellin peptides, not only in the cerebellum, but also in the extra-cerebellar tissues.

Successful treatment of primary adrenal non-Hodgkin's lymphoma associated with adrenal insufficiency.

We report a case of primary adrenal NHL associated with adrenal insufficiency which was successfully treated with steroid replacement and chemotherapy. A 69-year-old woman hospitalized with fatigue and weight loss developed shock and recovered with steroid therapy. Adrenal insufficiency was confirmed by an elevated plasma adrenocorticotropic hormone level and low cortisol. Computed tomography revealed large bilateral adrenal masses. Needle biopsy showed a diffuse, mixed B cell lymphoma. CHOP therapy accompanied by steroid replacement was begun, and she achieved a complete remission after 4 cycles. She received additional 4 cycles of chemotherapy. Although adrenal insufficiency was irreversible, she has continued in complete remission for 50 months at this reporting.

Corticomedullary mixed tumor of the adrenal gland with concurrent adrenal myelolipoma.

We report the case of a corticomedullary mixed tumor of the adrenal gland in a 55-year-old woman with a left adrenal mass who presented with mild symptoms of Cushing syndrome and an elevated urinary cortisol level. The patient underwent a left adrenalectomy. A well-circumscribed 2.5-cm mass, composed of an admixture of adrenal cortical cells and pheochromocytes, and an incidental 0.7-cm myelolipoma were present in the resected left adrenal gland. The diagnosis of adrenal corticomedullary mixed tumor was confirmed by both immunohistochemistry and electron microscopy. To our knowledge, this is the eighth well-documented report of this rare tumor.

[Specific binding of GABA in the adrenal glands and catecholamine blood and adrenal gland levels in rats under stress with inhibited functioning of the hypothalamus-hypophyseal-adrenocortical systems].

Forced swimming of intact rats was accompanied by an activation of the hormonal link in sympatho-adrenal system and by a decrease in the level of specific binding of 14C-GABA by adrenal plasma membranes; the former was prevented with the administration of GABAergic preparations (baclofen, GABA-taurine) before stress. Under inhibition of the function of hypothalamo-pituitary-adrenocortical axis following multiple hydrocortisone administration and, in presence of developing metabolic disorders and adrenal secretion of catecholamines, the latter reacted to stress by a decrease in adrenalin, noradrenaline and dopamine secretion without changing the intensity of specific binding of GABA. Administration of GABAergic preparations before stress prevented the development of stress disorders of noradrenaline and dopamine secretion partially or completely, and sodium thiosulphate administration increased acutely specific binding of GABA with adrenal plasma membranes simultaneously preventing the accumulation of adrenal noradrenaline and the decrease in blood DOPA level.

Adrenal crisis due to bilateral adrenal hemorrhage in primary antiphospholipid syndrome.

The authors report a case of a 56-year-old Thai woman with a history of recurrent venous thrombosis, spontaneous abortion and Graves' disease who presented with bilateral flank pain, nausea, vomiting and low-grade fever followed by hypotension. Adrenal crisis from bilateral adrenal hemorrhage was diagnosed by a low serum cortisol level during hypotension and bilateral hyperdense oval masses in each of the adrenal glands in a computerized tomographic study. Her hemostatic and serologic profile was compatible with primary antiphospholipid syndrome. Rapid improvement was observed after the administration of intravenous hydrocortisone. She was discharged on long-term glucocorticoid replacement for her primary adrenal insufficiency as well as an anticoagulant for prevention of thrombosis. The antiphospholipid syndrome should be suspected in a patient presenting with adrenal crisis without a distinct etiology.

Time to recovery of the hypothalamic-pituitary-adrenal axis after curative resection of adrenal tumors in patients with Cushing's syndrome.

The recovery time of the hypothalamic-pituitary-adrenal (HPA) axis after curative resection of adrenal tumors in patients with Cushing's syndrome is poorly documented. Eight consecutive patients were treated with a standardized hydrocortisone replacement strategy after curative resection of a cortisol-secreting tumor and the time to recovery of the HPA axis was determined. Hypercortisolism was documented by elevated 24-hour urinary free cortisol levels. Cure was documented by undetectable postoperative morning serum cortisol levels. Each patient received replacement hydrocortisone after surgery and was reevaluated every 3 to 6 months with an adrenocorticotrophic hormone (ACTH) stimulation test. Each patient was also monitored carefully for symptoms and signs of adrenal insufficiency, which was defined as symptoms consistent with this diagnosis that responded to increases in hydrocortisone levels. After surgical resection, each patient was cured of hypercortisolism. Subsequently, despite replacement hydrocortisone, each patient had symptoms of hypocortisolism, and in four of eight patients the dose of hydrocortisone was increased to relieve the symptoms. Patients required a median time of 15 months (range, 9 to 22 months) to recover a normal ACTH stimulation test and 19 months (range, 12 to 24 months) to allow discontinuation of replacement doses of hydrocortisone. The results suggest that surgical resection of a cortisol-secreting adrenal tumor will result in rapid cure of hypercortisolism, but complete recovery of the HPA axis and discontinuation of replacement steroids will require between 1 and 2 years. Normal adrenal function, as assessed by the cortisol response to ACTH, returns despite replacement doses of hydrocortisone, and replacement doses of hydrocortisone can be tapered rapidly or discontinued after a normal ACTH stimulation test.

[Hormone levels of the blood of the adrenal veins and inferior vena cava in patients with adrenal and kidney diseases].

Hydrocortisone and aldosterone concentration was determined in 138 patients with arterial hypertension of adrenal and renal genesis in the blood of the adrenal veins and in the cistern of the vena cava inferior, that of deoxycorticosterone in 50 patients, ACTH in 51 and renin activity in the blood plasma of the renal veins in 21 patients. The concentration of steroid hormones adequately reflected adrenal cortex function facilitating differential diagnosis between renal and adrenal pathology variants. Differential diagnostic analysis on the basis of change in the concentration of steroid hormones was found difficult or impossible if the patients received steroidogenesis changing drugs on day, preceding veno graphic examination of the adrenals.

[Experience with CT and adrenal venography in the diagnosis of adrenal disease with endocrine activity (author's transl)].

Report of the result of CT and venography in 12 patients with suspected adrenal disease, venography being combined with selective blood sampling for hormone analysis. In one patient CT showed a 1.6 cm big pheochromocytome in the left adrenal gland, not demonstrated by venography, but proven by analysis of the blood sample. Both methods showed hyperplasia of both adrenals in one patient with Cushing Syndrome with elevated Cortisol levels found in the analysis of the blood smples. Of 3 patients with hyperaldosteronism, venography was able to demonstrate 2 Conn adenomas, not seen on CT; whereas CT showed the third 2 X 1.5 cm big Conn adenoma hidden in an enlarged adrenal gland. Hormone analysis was helpful in 2 of these cases, while in the third it was misleading. The authors believe that both methods should be employed to localise over adrenal disease with endocrine activity.

We report a new case of primary adrenal lymphoma with latent adrenal insufficiency and long-term remission after hydrocortisone replacement therapy. We have analyzed 29 other cases described in the literature. This disease with poor prognosis can be revealed by an incidentally discovered, frequently bilateral, adrenal mass. Adrenal insufficiency may be latent and the diagnostic procedure should include both cortisol and ACTH determination with an additional ACTH stimulation test if appropriate. Early adrenal substitution can improve patient survival.

Plasma dehydroepiandrosterone sulfate levels in patients with hyperfunctioning and non-hyperfunctioning adrenal tumors before and after adrenal surgery.

To investigate the clinical significance of plasma dehydroepiandrosterone sulfate (DHEAS) measurements, 175 patients with histologically confirmed adrenal tumors, 10 cortisol-producing adenomas, 59 aldosterone-producing adenomas, 56 non-hyperfunctioning adenomas, 13 adrenocortical carcinomas, 13 adrenal cysts, and 24 adrenomedullary tumors were studied. Plasma DHEAS levels were expressed as percentage of the mean of sex- and age-matched groups of healthy, normal subjects (DHEAS %). We found that before adrenal surgery, DHEAS % values were significantly reduced in patients with cortisol-producing (mean, 15.2% of control; 95% confidence interval (CI), 9.4-24.7%), non-hyperfunctioning (28.4%; 22.4-36.0%) as well as aldosterone-producing adrenocortical adenomas (55.4%; 47.1-65.1%) compared with controls, while values were normal in patients with adrenal cysts and in those with adrenomedullary tumors. Plasma DHEAS % values exhibited a great variability in adrenocortical carcinomas (mean, 84.0%; 95% CI, 33.2-212.5%). Death from adrenocortical carcinoma was more frequent in patients with high plasma DHEAS % values compared with those with low DHEAS %. During long-term postoperative monitoring, we found that plasma DHEAS levels of patients with aldosterone-producing and non-hyperfunctioning adenomas returned to normal in the second and fourth postoperative year respectively. In patients with cortisol-producing adenomas, plasma DHEAS remained suppressed for as long as 8 years after the operation. These findings show that except in adrenocortical carcinomas and cysts, plasma DHEAS levels are significantly decreased in all groups of adrenocortical tumors, including non-hyperfunctioning and aldosterone-producing tumors. The extent of this decrease and the postoperative persistence of suppressed plasma DHEAS levels may be related to the glucocorticoid production of adrenocortical tumors.
