Hyponatremia as a Predictor of Cryptococcal Meningitis and Death Among Asymptomatic Persons With HIV and Cryptococcal Antigenemia

Among persons with human immunodeficiency virus-associated cryptococcal meningitis serum hyponatremia is a risk factor for mortality; however, the role of hyponatremia in persons with asymptomatic cryptococcal antigenemia is unknown. We found that serum hyponatremia <= 130 mmol/L is an independent risk factor for progression to meningitis and death in asymptomatic persons with cryptococcal antigenemia.
