SIADH in the context of localized Herpes-Zoster infection.

The uncommon association between the syndrome of inappropriate antidiuretic hormone secretion (SIADH) and localized Herpes-Zoster infection has been reported in only 16 cases in the literature. We present a case of a patient with Herpes-Zoster Ophthalmicus associated with Bell's Palsy who developed new-onset hyponatremia with criteria for SIADH. The patient was euvolemic and his laboratory results showed a concentration of serum sodium of 127 mmol/L, a serum osmolality of 266,9 mOsm/kg, a urinary osmolality of 259 mOsm/kg and a urine sodium concentration of 67,99 mmol/L. After excluding other possible causes, we concluded the diagnosis of SIADH secondary to the viral infection. He was treated with intravenous acyclovir for seven days, systemic corticoids and topical eye treatments. The vesicular lesions resolved with treatment and the serum sodium concentration progressively returned to normal levels, with a value of 136 mmol/L at discharge. Some complications further developed included herpetic keratitis and a corneal ulcer of the right eye. SIADH secondary to localized Herpes-Zoster is a rare entity, but it is important to be recognized by clinicians. This clinical case reinforces the hypothesis of the existence of a relationship between these two diseases, being the only case described associated with Bell's Palsy.
