A third case of acquired
phosphate diabetes
associated with a syndrome of inappropriate secretion of
antidiuretic hormone
(SIADH), related to a pulmonary tuberculosis, is reported. Renal hypophosphatemia in this patient was caused by the erroneous intake of 1 g doxycycline. It is likely that the selective nephrotoxicity in these 3 patients with SIADH was induced by tetracycline.

Four male divers were exposed to an environment of 1 ATA air for 7 d, followed by 7 d of 31 ATA He-O2, and following decompression to a postdive 1 ATA air environment for 3 d. Urine and blood were collected for hormonal measurements. Divided 24-h urine collections were obtained during 3 consecutive d at predive 1 ATA conditions, and at 31 ATA conditions. Two consecutive day collections were obtained at early decompression (31-25 ATA), at late decompression (14-8 ATA), and at postdive 1 ATA. Two blood samples were obtained, at predive 1 ATA, at 31 ATA, and at postdive 1 ATA. Plasma
antidiuretic hormone
(
ADH
) concentration decreased about 45% (P less than 0.005), while plasma aldosterone concentration and urinary aldosterone excretion were doubled (P less than 0.005) after the subjects were at 31 ATA. Plasma cortisol concentration and plasma parathyroid hormone concentration were not significantly affected by hyperbaria. Urinary excretion of aldosterone was not significantly different between day (0700-1900) and night (1900-0700) at any time, and both day and night excretion rates were increased at 31 ATA through late decompression (P less than 0.005). Urinary
ADH
excretion was greater during daytime at predive 1 ATA (P less than 0.005), but not thereafter. Both daytime and nighttime
ADH
excretion rates were decreased from 31 ATA through late decompression (P less than 0.005). It is concluded that hyperbaria eliminates the circadian release pattern of
ADH
and that the overall reduction of
ADH
may contribute to the increased free water clearance observed at hyperbaria. Also, increased parathyroid hormone was not associated with the
phosphaturia
observed at hyperbaria, but increased aldosterone coexisted with the increased kaliuresis observed.

We evaluated the effects of human calcitonin (hCT) on electrolyte excretion in hormone-deprived rats, that is, in the absence of endogenous parathyroid hormone,
antidiuretic hormone
, thyrocalcitonin and glucagon, the effects of which might have interfered with those of exogenous calcitonin. Plasma hCT levels, measured by radioimmunoassay, varied from 0 to 32 ng/ml. In these rats, hCT decreased magnesium (Mg) and calcium (Ca) excretion in a dose-dependent fashion. Maximal decreases were observed for hCT plasma concentrations comprised between 3 and 5 ng/ml, and persisted at the highest doses. Sodium, potassium, water, and total solute excretions were constant in the calcitonin concentration range explored. The same was observed for phosphate, except that slight but significant
phosphaturia
was elicited by the highest doses. Calcium and phosphate infusions to attenuate the fall in plasma Ca and phosphate concentration subsequent to hCT infusion, did not alter the hormonal effect on Ca and Mg excretion. hCT can therefore directly modulate Mg and Ca reabsorption by the kidney at plasma concentrations within the physiological range. The maximal effects on Mg and Ca reabsorption were obtained at plasma concentrations which are generally reached after maximal stimulation of endogenous calcitonin secretion. It is suggested that in rats, endogenous secretion of calcitonin stimulates Ca and Mg renal reabsorption without modification of sodium and phosphate excretion.

Micropuncture and clearance studies were performed on normal untreated and polyuric lithium chloride treated rats (10-12 days). A persistent hypernatremic state quickly developed in the polyuric lithium treated rats during hydropenia resulting from an increased urinary loss of water over sodium chloride, as the fractional excretion of sodium remained at control levels. Superficial proximal tubule and loop of Henle fluid reabsorption was depressed by 8 and 17%, respectively, in lithium-treated rats during this period. By contrast, water reabsorption in the distal tubule and collecting system was significantly increased in the lithium animals, being 27% of the filtered load compared with 20% in normal rats. These results suggest that the urinary-concentrating defect induced by lithium treatment is due primarily to a depression of proximal tubule and possibly loop of Henle function, and that water reabsorption within the distal nephron may in fact be augmented: thus it is unlikely that the action of
antidiuretic hormone
is significantly impaired. Marked
phosphaturia
and hypocalciuria were also noted in the lithium-treated rats.

We report a case of
phosphate diabetes
in a patient with the syndrome of inappropriate secretion of
antidiuretic hormone
(SIADH) associated with sarcoidosis. Our patient was affected by systemic sarcoidosis and he fits the criteria of Schwartz for the diagnosis of SIADH. He presented with
phosphate diabetes
which appeared during demeclocycline (DMC) therapy and persisted for about 1 month from the end of DMC. It constitutes the fourth case of
phosphate diabetes
induced by tetracycline described in the literature and it is the third case of SIADH associated with sarcoidosis.

Recollection micropuncture study was performed in 11 thyroparathyroidectomized dogs during antidiuresis to determine the effect of continuous
vasopressin
infusion at 50 mU/kg/h on proximal tubule phosphate and sodium transport. The animals were divided into two groups according to changes in mean arterial blood pressure. In the first group (five dogs) with increased blood pressure and glomerular filtration rate (GFR), mean proximal tubule fluid-to-plasma inulin ratio fell significantly from 1.69 to 1.53, whereas it remained unchanged at 1.60 in the second group (six dogs) with no change in blood pressure. In contrast, mean proximal tubule fluid-to-plasma ultrafilterable phosphate ratio increased consistently in both groups, regardless of blood pressure changes. Since natriuresis as well as
phosphaturia
were observed in all animals, the sodium effect of
vasopressin
in the distal nephron must be mainly responsible for the natriuresis. It was concluded that
vasopressin
, when given in the doses employed, inhibits phosphate transport in the proximal tubule and sodium reabsorption in the distal nephron. An additional effect on proximal tubule sodium reabsorption appears to be related to the rise in blood pressure and GFR secondary to
vasopressin
administration.
