The serum sodium to urinary sodium ratio divided by the (serum potassium)2 to urinary potassium ratio (SUSPPUP formula) reflects aldosterone action. We here prospectively investigated into the usefulness of the SUSPPUP ratio as a diagnostic tool in primary hyperaldosteronism. Parallel measurements of serum and urinary sodium and potassium concentrations (given in mmol/L) in the fasting state were done in 225 patients. Of them, 69 were diagnosed with primary aldosteronism (PA), 102 with essential hypertension (EH), 26 with adrenal insufficiency (AI) and 28 did not suffer from the above-mentioned disorders and were assigned to the reference group (REF). The result of the SUSPPUP formula was highest in the PA group (7.4, 4.2–12.3 L/mmol), followed by EH (3.2, 2.3–4.3 L/mmol), PA after surgery (3.9, 3.0–6.0 L/mmol), REF (3.4 ± 1.4 L/mmol) and AI (2.9 +/− 1.2 L/mmol). The best sensitivity in distinguishing PA from EH was reached by multiplication of the aldosterone to renin-ratio (ARR) with the SUSPPUP formula (92.7% at a cut off > 110 L/mmol), highest specificity was reached by the SUSPPUP determinations (87.2%). The integration of the SUSPPUP ratio into the ARR helps to improve the diagnosis of hyperaldosteronism substantially.

Background: The urinary sodium potassium (NaK) ratio is associated with dietary sodium and potassium intake and blood pressure, and it also reflects the activity of aldosterone. Herein we evaluated the value of the urinary NaK ratio in predicting the surgical outcomes of patients with unilateral primary aldosteronism (uPA). Methods: This non-concurrent prospective cohort study was conducted from 2011 to 2017 and included 241 uPA patients who had undergone adrenalectomy. Predictors of successful clinical outcomes were analyzed using logistic regression. Results: Among the 241 uPA patients, 197 (81.7%) achieved clinical complete or partial success. A urinary sodium potassium ratio <3 (odds ratio (OR): 2.5; 95% confidence interval (CI): 1.2–5.4; p = 0.015), body mass index <25 kg/m2 (OR: 2.82; 95% CI: 1.31–6.06; p = 0.008), renin <1 ng/mL/h (OR: 2.51; 95% CI: 1.01–6.21; p = 0.047) and mean preoperative blood pressure >115 mmHg (OR: 5.02; 95% CI: 2.10–11.97; p < 0.001) could predict clinical success after adrenalectomy. Furthermore, higher pre-treatment plasma aldosterone (OR: 1.014; 95% CI 1.005–1.024; p = 0.002) or lower serum potassium (OR: 0.523; 95% CI: 0.328–0.836; p = 0.007) were correlated with lower urinary NaK ratio (<3), and log urinary NaK ratio was positively correlated with serum C-reactive protein ( β value 2.326; 95% CI 0.029–4.623; p = 0.047). Conclusions: uPA patients with a lower urinary NaK ratio, due to high plasma aldosterone and low serum potassium concentrations, were more likely to have clinical success after adrenalectomy. uPA patients with a higher urinary NaK ratio were associated with more severe inflammatory status, and possibly more resistant hypertension post-operatively.

A 6-year-old girl developed generalized seizures followed by coma, five days after surgical removal of a craniopharyngioma. Low serum sodium levels and low serum osmolality with inappropriately high urinary sodium output confirmed the diagnosis of inappropriate antidiuretic hormone (ADH) secretion. Treatment with 3% hypertonic saline solution and repeated doses of furosemide (1 mg/kg) improved her clinical condition; serum sodium levels, however, rose slowly and urinary excretion remained high. Deoxycorticosterone acetate (DOCA), 4 mg/sq m/day, was added to the above regimen. A striking clinical improvement was noted. Serum sodium levels returned to normal with a concomitant sharp decline in urinary sodium output. The clinical course of this patient demonstrates the efficacy of the addition of deoxycorticosterone acetate to hypertonic saline and furosemide in the treatment of severe, lifethreatening hyponatremia due to the syndrome of inappropriate antidiuretic hormone seretion.

The effect of heat (35 degrees C) and dehydration under heat (30 h) on plasma levels of antidiuretic hormone (ADH) and aldosterone was studied on four nonpregnant dry Holstein cows. Heat exposure caused a rapid significant rise in plasma ADH without significant changes in hematocrit (Hct), small but significant increase in urine output and a significant reduction in total plasma protein. Dehydration under heat caused a sharp increase in ADH levels associated with a significant decrease in urine output and a significant increase in plasma protein, blood Hct, and serum osmolality. A significant reduction in plasma aldosterone level was observed after 24 h of heat exposure. This was associated with a slight rise in urinary sodium excretion and a significant reduction in serum sodium. Both serum and urinary potassium concentrations were significantly lower under heat. Dehydration resulted in a slow rise in aldosterone but did not reach thermoneutral level. This is probably due to the inhibitory effect of higher serum sodium observed during dehydration on plasma aldosterone secretion. The rise in ADH and decrease in aldosterone during heat exposure may explain why cattle are one of the few species that do not concentrate urine during heat exposure.

Significant Difference

Male rats were placed in a cage either 8 in. x 8 in. x 10 in. (free) or 2 in. x 2 in. x 8 in. (restrained) and exposed to ambient temperatures between 40° and 60°C. ‘Restrained’ rats died sooner than ‘free’ animals at all temperatures. There was no significant difference between final rectal temperatures of free and restrained rats at ambient temperatures greater than 40°C; mean for these groups was 44.6°C. At 40°C the final rectal temperature was slightly lower in the restrained group (43.4° vs. 44.6°C). Restraint had no significant effect on the constituents of the blood examined. Serum potassium and specific gravity and blood hematocrits were increased and serum sodium was unchanged in heat-exposed rats compared with controls at 26°C. Serum calcium varied irregularly with exposure temperature. Submitted on December 23, 1958
