Hyponatremia with simultaneous renal sodium loss was associated with the inappropriate secretion of antidiuretic hormone in a dog with heartworm disease. Antidiuresis caused expansion of extracellular fluid volume, which induced renal salt wasting and a negative sodium balance. The combination of water retention, salt wasting, and inactivation of intracellular solute contributes to the decrease in serum sodium concentration. Water intoxication due to hypotonicity of body gluids induced anorexia, depression, weakness, and incoordination.

We report a 52-year-old male patient with Shy-Drager syndrome (SDS) complicated by an occurrence of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). The patient first developed impotence at the age of 48, accompanied by urinary incontinence, and episodes of dizziness while standing. The following year, the patient had developed a staggering gait and speech became monotonous. At age 52, the patient was admitted to the hospital after experiencing frequent episodes of syncope associated with complete loss of consciousness. Upon examination, blood pressure was 100/70 in a recumbent position, and 80/60 when standing. The pulse rate varied from 60 per minute to 62. The patient was alert. The alternating Horner sign was observed, and a paucity of facial movements was visible. His speech was slow and monotonous. Muscle tone was increased bilaterally. There was incoordination. A laboratory examination revealed reduced serum sodium levels of 127 mEq/L and increased sodium excretion with plasma hypoosmolality (262 mOsm/kg/H), urine hyperosmolality and low serum renin activity (0.2 ng/ml/h). Renal functions were normal and the levels of adrenocortical and thyroid hormones were normal. There were no abnormalities observed in the chest roentgenogram taken. The level of antidiuretic hormone (ADH) was unreasonably high (5.74 pg/ml). A water-load test demonstrated failure of both water diuresis and inhibition of ADH secretion. These data suggested that hyponatremia in this case was caused by SIADH. The correlation between plasma osmolality and the concentration of ADH suggested that osmolality that initiates ADH release appeared to have been reset to around 230 mOsm/kg lower than normal.(ABSTRACT TRUNCATED AT 250 WORDS)

Arginine8-vasopressin (AVP, 10 micrograms), injected s.c., potentiated the motor-impairing effects of pentobarbital (10-20 mg/kg) injected i.p. in rats 1 h after AVP. Motor incoordination was assessed on the moving belt task. However, AVP (0.1-100 nM) failed to enhance pentobarbital potentiation of GABA-mediated 36Cl- uptake in rat cerebral cortical or cerebellar microsacs. There was also no effect of a 10 micrograms s.c. injection of AVP 1 h before killing, on pentobarbital potentiation of GABA-mediated chloride flux in either cerebral cortical or cerebellar microsacs.
