We report a case of syndrome of inappropriate secretion of antidiuretic hormone (SIADH) with accompanying severe strongyloidiasis in a 52-year-old male. On admission, he showed drowsiness and emaciation with severe hyponatremia. We gave sodium (saline or salts) in an i.v. drip infusion and orally without improvement. A urinalysis and plasma osmotic pressure test indicated SIADH, therefore, treatment was changed to restrict his sodium intake. The hyponatremia gradually improved initially, but the appetite loss, nausea, and hyponatremia continued. Endoscopy revealed white patches on the stomach wall and histopathological examination revealed infestation of the mucosal epithelium with numerous Strongyloides stercoralis larvae. Ivermectin treatment was then initiated and the abdominal symptoms and hyponatremia gradually resolved. We carefully investigated the underlying cause of the SIADH, such as disease of the central nervous system, lung cancer, and other malignancies, but no abnormality or clear cause could be found. We concluded that the patient developed SIADH secondary to severe S. stercoralis infection.

This study presents a case of severe water intoxication in a female patient with delusional infestation. Self-induced excessive water ingestion is a rare medical condition, which has not been reported in patients with delusional infestation yet. The patient in this case study was a 60-year-old Chinese woman, who was admitted to our hospital because of a feeling of skin infestation. She suffered from loss of consciousness and generalized tonic-clonic seizure after drinking 12 L of water during bowel cleansing before colonoscopy. Sufficient laboratory and imaging examinations were performed to exclude other possible causes of severe hyponatremia, such as hypothyroidism, diabetes insipidus, and syndrome of inappropriate antidiuretic hormone. Besides, the cystic lesion in the posterior pituitary revealed by cranial magnetic resonance imaging was not accountable for her delusional symptoms as well as excessive drinking behavior. Her delusional symptoms were in complete remission with a combination of risperidone and aripiprazole. However, nearly 3 months after discharge, this patient suffered from depressed mood and was diagnosed with depressive syndrome, and even attempted suicide. This case highlights the possibility of self-induced water intoxication in patients with delusional infestation, inevitably adding to the complexity of the disease, and indicates the necessity of precautions for secondary psychotic or mood problems after symptomatological remission.
