A 3-year-old, spayed female, domestic shorthaired cat was presented for evaluation of liver disease. Following anesthesia, laparoscopy, and medical therapy, the cat developed severe hyponatremia that was unresponsive to fluid therapy. Further evaluation of serum and urine osmolality determined that the cat fulfilled the criteria for syndrome of inappropriate antidiuretic hormone secretion. Treatment with fluid restriction resulted in resolution of the hyponatremia and clinical signs associated with the electrolyte imbalance.

Truncal Ataxia

A 13-month-old, male bichon frise was examined for the investigation of intermittent seizures, ataxia, abnormal behavior, polyuria, and polydipsia. At presentation, clinical and neurological examinations were unremarkable with the exception of mild truncal ataxia and a domed skull. Severe hyponatremia and hypoosmolality were identified, and following diagnostic testing a diagnosis of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) was made. Magnetic resonance imaging revealed changes consistent with severe hydrocephalus. Water restriction resulted in increased serum osmolality and a reduction in severity of clinical signs. The current case report documents SIADH associated with hydrocephalus in a dog. Structural brain disease should be excluded before a diagnosis of idiopathic SIADH is made.

Positive Treatment

ObjectiveTolvaptan, an oral antagonist of the vasopressin V2 receptor, has been found to improve hyponatremia in patients with mixed etiologies. This study analyzed a subgroup of patients with the syndrome of inappropriate antidiuretic hormone secretion (SIADH) to evaluate the efficacy and safety of tolvaptan in this group.Design and patientsHyponatremic patients in the SALT-1 and SALT-2 studies with a diagnosis of SIADH were identified based on clinical diagnosis by individual study investigators. Subjects were randomized to receive oral placebo (n=52) or tolvaptan 15 mg daily, with further titration to 30 and 60 mg daily, if necessary, based on the response of serum [Na+] (n=58).ResultsIn patients with SIADH, improvement in serum [Na+] was significantly greater (P<0.0001) with tolvaptan than placebo over the first 4 days of therapy as well as the entire 30-day study, with minimal side effects of increased thirst, dry mouth, and urination. Only 5.9% of tolvaptan-treated patients had overly rapid correction of hyponatremia as defined by current guidelines. After discontinuation of tolvaptan, serum [Na+] declined to values similar to placebo. A significant positive treatment effect favoring tolvaptan on the physical component, and a near-significant trend on the mental component, was found using the SF-12 Health Survey. Tolvaptan was associated with a significantly reduced incidence of fluid restriction.ConclusionsResults for the SIADH subgroup were analogous to those of the combined SALT population regarding efficacy and safety but demonstrated a greater improvement in the physical component of the SF-12 Health Survey than in the full mixed etiology SALT patient group.

Repeated Use

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) has been recognized to occur following treatment with vincristine. None of the reports have provided information regarding its potential for recurrence on further challenge with vincristine (VCR), an agent generally required for repeated use in patients with malignancies. Symptomatic hyponatremia and SIADH that occurred 8 days following administration of VCR in a child with acute lymphatic leukemia was documented with specific radioimmunoassay of urinary ADH levels. The further occurrence of recurrent elevations in ADH excretion 8–10 days following repeated treatment with VCR was also observed. However, SIADH was prevented by prophylactic rigorous fluid restriction. The occurrence of SIADH following VCR therefore does not preclude the further safe usage of this drug.

First Case

Hyponatremia (serum Na levels of <135 mEq/L) is the most common electrolyte imbalance encountered in clinical practice, affecting up to 15–28% of hospitalized patients. This case report refers to a middle-aged man with severe hyponatremia due to Syndrome of Inappropriate Antidiuretic Hormone Secretion related to four possible etiological factors: glossopharyngeal squamous cell carcinoma, cisplatin treatment, right basal pneumonia with Pseudomonas aeruginosa, and the treatment with Levofloxacin. This case report discusses a rare complication of common conditions and of a common treatment. To our knowledge this is the first case of hyponatremia related to Levofloxacin and the second related to fluoroquinolones.

Abstract Background Syndrome of inappropriate antidiuretic hormone secretion can be caused by arginine-vasopressin-producing tumors or enhanced arginine vasopressin secretion from the posterior pituitary gland due to central nervous system disorders and intrathoracic diseases. Case presentation A 53-year-old Asian man was hospitalized with complaints of tremor and hiccups. Laboratory examination revealed findings suggestive of hypotonic hyponatremia due to syndrome of inappropriate antidiuretic hormone secretion. The patient did not complain of headache or photophobia, and showed no signs of meningeal irritation. Positron emission tomography–computed tomography revealed 18F-fluoro-deoxy-glucose accumulation along the cervical spinal cord, based on which the patient was diagnosed as having aseptic meningitis. The hyponatremia was treated successfully by fluid restriction, and optimum plasma sodium concentration was maintained by tolvaptan administration. Conclusions This case underscores the need to consider the possibility of mild meningitis as the cause of syndrome of inappropriate antidiuretic hormone secretion in patients without other identifiable cause.

Coronavirus disease 2019 (COVID-19) was first reported in Wuhan, China, in December 2019. The disease is caused by severe acute respiratory syndrome virus coronavirus 2 (SARS-CoV-2). A few published cases have linked COVID-19 and hyponatremia. The mechanism of hyponatremia in these cases is related to the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Here we present a unique case of urinary retention and SIADH as unusual presenting features of SARS-CoV-2 infection.
