A 71-year-old female with amyotrophic lateral sclerosis (ALS) developed the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) during respiratory failure due to atrophy of the respiratory muscles. Serum sodium concentration fell to 116 mEq/l and then returned to the normal range after water restriction and respiratory care. This is considered to be the first case report of ALS associated with SIADH.

SK&F 101926 is a synthetic octapeptide which was designed to promote free water excretion by antagonizing the action of antidiuretic hormone. The clinical and pathologic changes in rats resulting from lethal doses of SK&F 101926 have suggested that death is associated with respiratory failure and/or cardiovascular collapse. To define the relationships between respiratory failure, cardiovascular collapse, and death, respiratory and cardiovascular parameters were monitored in anesthetized rats following the intravenous administration of SK&F 101926 at a dosage (3 mg/kg) which resulted in 70% mortality. Within 5 min after receiving this dosage, mean arterial blood pressure was reduced to values between 30 and 40 mm Hg in all rats. This degree of hypotension was well tolerated by some rats and, consequently, was not considered to be the cause of death. Deaths occurred between 9 and 58 min after dosing and were preceded by respiratory depression involving marked reductions in respiratory rate and the lack of compensatory increases in tidal volume. At the time of respiratory arrest, heart rates remained above 200 beats/min, mean arterial blood pressure remained between 30 and 40 mm Hg, and there were no consistent changes in dynamic lung compliance or total pulmonary resistance. Pretreatment of rats with a mast cell stabilizing agent (disodium cromoglycate), a mast cell degranulating agent (compound 48/80), or a histamine/5-hydroxytryptamine blocking agent (cyproheptadine) prevented the reductions in respiratory rate and death caused by SK&F 101926. These pretreatments also reduced the effect of SK&F 101926 on blood pressure, but were not able to completely prevent the hypotension.(ABSTRACT TRUNCATED AT 250 WORDS)

The major complication of extracorporeal membrane oxygenation (ECMO) for the treatment of neonatal respiratory failure is bleeding related to heparinization. Systolic hypertension has emerged as another serious side effect in our experience. Thirty-eight of the first 41 newborns we treated with ECMO developed a systolic blood pressure greater than 90 mm Hg. The mean hypertension index (HI blood = hours greater than 90/hr on ECMO) was 0.17 +/- 0.16. Possible biochemical mediators were assayed in 17 patients. Plasma renin activity (PRA), aldosterone, epinephrine, norepinephrine, prostaglandin E2, thromboxane, and antidiuretic hormone were elevated. Angiotensin-converting enzyme (ACE) and prostacyclin were not elevated. Eighteen patients (44%) had intracranial hemorrhage (ICH), and 11 patients (27%) had clinically significant ICH. The HI was significantly (p less than 0.005) lower in those patients without ICH (0.11 +/- 0.01) than in those patients with ICH (0.25 +/- 0.04). PRA at hour 12, day 2, and day 3 was significantly higher (p less than 0.05) in patients experiencing ICH (62 +/- 42; 93 +/- 15; 73 +/- 30 ng/ml/hr) than in those without ICH (27 +/- 25; 14 +/- 8; 12 +/- 4 ng/ml/hr). An aggressive approach to medical management evolved that included hydralazine, nitroglycerine, and captopril, which protected against ICH. Two of 23 patients (9%) treated with the protocol sufferred clinically significant ICH, whereas nine of 18 patients (50%) treated before implementation of the protocol experienced ICH. The ACE inhibitor captopril was most effective in the control of hypertension. We conclude that systolic hypertension is common during neonatal ECMO, is associated with ICH, and is related to a high PRA. Aggressive management of hypertension during ECMO can reduce the incidence of ICH, and captopril is an important component of this aggressive medical management.

Normal osmoregulation is maintained by the proper function and interplay of factors influencing thirst, renal water metabolism, and vasopressin secretion. In pathophysiologic states, body water homeostasis is disrupted and hyponatremia ensures. Hyponatremia associated with cardiac failure, hepatic failure, respiratory failure, diabetes mellitus, the postoperative state, and other disorders is commonly found in the critical care setting. The pathophysiology, diagnosis, and treatment of hyponatremia are discussed.

Because renal function and electrolyte balance are commonly altered in premature infants, particularly those requiring ventilatory support, we studied the influence of assisted ventilation on renal electrolyte and water excretion in infants with birth weights less than 1501 g during the 2 days after birth. Twenty-two infants receiving assisted ventilation, either as intermittent mandatory ventilation or nasal continuous positive airway pressure, were compared with 21 spontaneously ventilating infants of similar birthweight and gestational age. Mean (and SEM) creatinine clearance was lower (p less than 0.05) in the assisted ventilation group on day 1 (2.9 +/- 0.4 versus 4.1 +/- 0.4 ml/min/1.73 m2) and on day 2 (4.1 +/- 1.0 versus 6.8 +/- 0.8 ml/min/1.73 m2, p = 0.05), and there was a correlation between creatinine clearance and mean blood pressure in both groups. Mean urine vasopressin was higher in the assisted ventilation group on the first day (360 +/- 86 versus 123 +/- 30 pg/mg creatinine; p less than 0.02) and correlated with higher urine osmolality. There were no differences in urine volume, in osmolar or free water clearances, or in the intake and urine excretion of sodium, potassium, and chloride. Plasma renin activity, urine aldosterone, and urine prostaglandin E2 were similar in both groups on both days. Neither the mode of assisted ventilation nor the cause of respiratory failure appeared to affect these results.

Sudden unexplained death may be seen with treatment of craniovertebral anomalies and surgery of the upper cervical spine. Death is due to sleep-induced apnea, premonitored by periods of confusion, lethargy, and asthenia. There may be associated hypotension, bradycardia, hyponatremia, hypothermia, inappropriate antidiuretic hormone secretion, and difficulty in micturition. The potential for respiratory failure may be predicted if a CO2 response test demonstrates an attenuated or abnormal response. Apnea during sleep may be reversed by arousal or may require ventilatory support for a period of time. The condition is self-limiting, but remains the major life-threatening complication. Both apnea and autonomic dysfunction are treatable and curable with appropriate diagnosis and management.

We experienced three patients who have collagen diseases with respiratory failure accompanied by hyponatremia. They were one systemic lupus erythematosus patient with interstitial pneumonia, one rheumatoid arthritis patient with acute pneumonitis, and one dermatomyositis patient with pulmonary fibrosis and organizing pneumonia. In all 3 patients, hyponatremia appeared along with a decrease in arterial O2 partial pressure (PaO2) and the hyponatremia tended to improve when the PaO2 increased after inhalation of oxygen, even though their respiratory failure were not improved. In dermatomyositis patient, serum Na levels were over-corrected after increase in PaO2. The serum and urine osmolality, serum antidiuretic hormone (ADH) levels and clinical pictures demonstrated a presence of inappropriate secretion of ADH (SIADH) in all 3 cases when hyponatremia and hypoxia appeared. A close association between hyponatremia and hypoxia observed in 3 patients strongly suggested that their SIADH were associated with hypoxia since SIADH could be demonstrated by hypoxia. Therefore, it is important to realize that hypoxia-induced hyponatremia will be promptly corrected to hypernatremia by an oxygen inhalation, which could cause a lethal central pontine myelinolysis.

We report 2 autopsy-proven cases of motor neuron disease/amyotrophic lateral sclerosis (MND/ALS), who developed the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) prior to the respiratory failure. With respect to the underlying mechanisms of SIADH in the cases, we considered two factors; 1) dysfunction of the feedback system in ADH secretion via intrathoracic volume receptors caused by changes in intrathoracic circulation, and 2) primarily functional abnormalities in the limbic system which could influence hypothalamic osmoreceptors. It appears that SIADH can be followed by an exacerbation of respiratory dysfunction in MND/ALS.

A 48 year-old white male not suffering from endocrine disease or polydipsia, not taking diuretics, and suffering from no renal disease was started on risperidone and discharged on no other drug from Western Missiouri Mental Health Center (WMMHC) after an 8-day hospitalization. Seven days later he was admitted to a university medical center with generalized seizures, hyponatremia, respiratory failure, and rhabdomyalysis. He eventually recovered, was transferred back to WMMHC, and stabilized on appropriate medication. A search of the literature indicates no case reports linking risperidone to hyponatremia. It is assumed that the mechanism of hyponatremia is similar to other psychotropic medication in that it is secondary to the syndrome of inappropriate antidiuretic hormone (SIADH).
