Many hormones initiate their biologic actions by augmenting the intracellular concentrations of 3',5'-adenosine monophosphate (cyclic AMP). The nucleotide has been found in body fluids; its determination in plasma and urine can be performed by a rapid, simple and specific method: the cyclic AMP assay kit of the Radiochemical Centre (Amersham, England). The assay is based on the competition between unlabelled cAMP and a fixed quantity of the tritium labelled compound for binding to a bovine muscle protein which has a high specificity and affinity for cAMP. Different factors must be considered in evaluating the 24 h urinary content of the nucleotide: the renal or extrarenal origin of cAMP and the functional status of the kidneys. In basal conditions the urinary cAMP excretion is significantly correlated with creatinine excretion (n = 67; r = 0.47; p less than 0.001) thus confirming that the most part of cAMP excreted is derived from the plasma by glomerular filtration. Parathyroid hormone (PTH) stimulates adenylate cyclase predominantly in the renal cortex, whereas vasopressin (ADH) stimulated the enzyme in the medulla; thus PTH and ADH could increase the amount of cAMP in the urine from the renal source. In a case of diabetes insipidus and infusion of ADH caused a prompt rise in cAMP urinary excretion. In 5 normals an infusion of bovine synthetic parathyroid hormone caused an increased excretion of cAMP that preceded the phosphaturic response. An infusion of salmon synthetic calcitonin caused a rise in phosphate excretion and no increase in cAMP urinary content. As it concerns the two calciotopic hormones, PTH and CT, it is reasonable to assume that renal receptors are distinct. The 24 h urinary excretion of cAMP in 55 control subjects (3613 +/- 1460 D.S. n moles) was contrasted with the lower excretion in 25 elderly subjects (70-93 years: 1804 +/- 699 n moles), with the high cAMP excretion in a patient with hyperparathyroidism (that fell to normal values following removal of the parathyroid adenoma) and with the low cAMP excretion in patients with primary or surgical hypoparathyroidism. The mean 24 h cAMP excretion in patients with renal insufficiency was significantly decreased when compared to control subjects. These findings and recent reports confirm that the 24 h urinary output of cAMP may be considered an useful index of pharathyroid function in man.

A case of central diabetes insipidus is reported in association with idiopathic hypoparathyroidism, adrenal failure and mucocutaneous candidiasis. The diabetes insipidus was recognised at the same time as the discovery of aldosterone and cortisol deficiency, and occurred several years after the initial onset of mucocutaneous candidiasis and hypocalcaemia. Control of the diabetes insipidus was achieved initially with nasal aqueous lysine vasopressin and later with desmopressin. The development of diabetes insipidus may be a further aspect of endocrine secretory failure associated with idiopathic hypoparathyroidism.

Among the factors, which may influence on the uric acid metabolism, the excess or deficiency of some hormones apparently induces the abnormal serum uric acid level. We described hyperuricemia and hypouricemia associated with endocrine disorders. Hyperuricemia due to the increased production of uric acid is observed in myopathy associated with hypothyroidism, hyperthyroidism or hypoparathyroidism. Hyperuricemia due to the decreased renal uric acid clearance is associated with hypopituitarism, hypothyroidism, hyperparathyroidism, central diabetes insipidus, nephrogenic diabetes insipidus, Bartter syndrome, and diabetic ketoacidosis. Hypouricemia due to the increased renal uric acid clearance is associated with hypoparathyroidism, primary aldosteronism and inappropriate secretion of antidiuretic hormone (SIADH).

This case is a report of a male, 52 year old, heavy smoker, with a history of about 10 years of alcohol abuse (he quitted in 1993), gastric resection for ulcer (Billroth II 1970), hypoparathyroidism and macroamylasemia, died for undiagnosed pancreatic carcinoma revealed at necroscopy. The only clinical evidence of carcinoma were pulmonary metastasis and paraneoplastic syndrome characterized from hyponatriemia due to inappropriate secretion of antidiuretic hormone and elevation of seric calcium caused by parathyroid hormone related protein. In patients without endocrine abnormalities, such unusual paraneoplastic syndrome could cause hypercalcemia, but in our patient, the increased calcemia did not reach abnormal levels due to the previous hypoparathyroidism. At present time, there are no clinical reports of parathyroid related protein secretion by pancreatic carcinoma and therefore, it could speculate that this modification together with ectopic secretion of antidiuretic hormone, represent a peculiar evidence of otherwise unknown and undetectable pancreatic carcinoma.

This study presents a cross-sectional analysis of the hormonal alterations of patients with visceral leishmaniasis. The diagnosis was established by the bone marrow aspiration and polymerase chain reaction test. Primary adrenal insufficiency was observed in 45.8% of patients; low aldosterone/renin plasma ratio in 69.4%; low daily urinary aldosterone excretion in 61.1%; and low transtubular potassium gradient in 68.0%. All patients had normal plasma antidiuretic hormone (ADH) concentrations, hyponatremia, and high urinary osmolality. Plasma parathyroid hormone was low in 63%; hypomagnesemia was present in 46.4%, and increased Mg(++)(EF) in 100%. Primary thyroid insufficiency was observed in 24.6%, and secondary thyroid insufficiency in 14.1%. Normal follicle-stimulating hormone plasma levels were present in 81.4%; high luteinizing hormone and low testosterone plasma levels in 58.2% of men. There are evidences of hypothalamus-pituitary-adrenal axis abnormalities, inappropriate aldosterone and ADH secretions, and presence of hypoparathyroidism, magnesium depletion, thyroid and testicular insufficiencies.
