Neuromyelitis optica (NMO) has been reported to be associated with endocrinopathies, such as amenorrhea, galactorrhea, and diabetes mellitus. However, its association with the syndrome of inappropriate antidiuretic hormone secretion (SIADH) is extremely rare. We herein report an adult case of NMO with SIADH in a female Chinese patient. The patient was aquaporin-4 antibody positive, and her hypo...

An 11-year-old boy developed severe syndrome of inappropriate antidiuretic hormone secretion (SIADH) after diagnosis of an intracranial B-cell lymphoma. His sodium levels dropped to 118-120 mmol/L despite 70% fluid restriction. For chemotherapy, he required hyperhydration, which posed a challenge because of severe hyponatraemia. Tolvaptan is an oral, highly selective arginine vasopressin V2-rec...

BACKGROUND Hyponatremia based on syndrome of inappropriate antidiuretic hormone hypersecretion (SIADH) is observed in up to 15% of patients with small cell lung cancer (SCLC). The electrolyte imbalance is associated with a high morbidity and mortality and often delays appropriate treatment. Management of hyponatremia proved to be challenging until new vasopressin-2 receptor antagonists such as ...

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...

Paraneoplastic syndrome (PNS) related to lung cancer is very common. However, the syndrome of inappropriate anti-diuretic hormone secretion (SIADH) is rare in non-small cell lung cancer (NSCLC). We are reporting the case of a 58-year-old female presenting with dyspnea, cough, weight loss, digital clubbing, and one week of haemoptysis. CT showed a mediastinal mass completely encasing her superio...

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a rare complication of adult Still's disease (ASD). We experienced a male ASD patient who complained of arthralgia and intermittent fever. Chest radiograph and pleural fluid analysis revealed pleurisy with effusion. We diagnosed this patient with SIADH and confirmed the disappearance of hyponatremia and pleurisy after starting ...

UNLABELLED The syndrome of inappropriate antidiuretic hormone secretion (SIADH) can occur following traumatic brain injury (TBI), but is usually transient. There are very few case reports describing chronic SIADH and all resolved within 12 months, except for one case complicated by meningo-encephalitis. Persistent symptomatic hyponatremia due to chronic SIADH was present for 4 years following a...

We present a case of cytarabine-induced syndrome inappropriate secretion antidiuretic hormone (SIADH), rare manifestation and complication, which based on review the medical literature was reported only in one prior report. It involves 74-year-old male with acute myeloid leukemia who developed asymptomatic hyponatremia during three cycles consolidation chemotherapy high-dose cytarabine (HiDAC)....

It is well documented that central nervous system (CNS) infections may lead to syndrome of inappropriate anti-diuretic hormone secretion (SIADH), but diagnosing these can prove difficult in patients with atypical presentations. We present a case of SIADH and muscle weakness in a patient without typical signs of CNS infection who was tested and diagnosed with neuroborreliosis based largely on he...

BACKGROUND AND OBJECTIVES The pathogenesis of hyponatremia (serum sodium <135 mEq/L) in Kawasaki disease (KD) remains unclear. We investigated the clinical significance of hyponatremia, and the role of interleukin (IL)-6 and IL-1β in the development of hyponatremia and syndrome of inappropriate antidiuretic hormone secretion (SIADH) in KD. SUBJECTS AND METHODS Fifty KD patients were prospecti...
