The number of people who may be at risk for meningitis shot up dramatically on Monday, as federal officials expanded the list of medications being investigated for possible contamination at a Massachusetts drug company.
The Food and Drug Administration warned that a second steroid has been linked to a possible case of fungal meningitis, and that a heart surgery drug and all injectable medications made by the same company, New England Compounding Center (NECC), are now suspect.
Anyone who got the drugs "should be alerted to the potential risk of infection," the FDA said.
The new warnings prompted the Minnesota Department of Health to expand its search for patients who may have been affected. Many more people in the state may be getting phone calls in coming days, state officials say.
"We don't know in Minnesota how many clinics or hospitals or doctors' offices received these [products]," said Richard Danila, deputy Minnesota state epidemiologist. But he said the number "may be quite large."
As of Monday, 214 cases and 15 deaths have been reported in 15 states, including five cases of meningitis in Minnesota. All were tied to an injectable steroid contaminated with fungus.
The latest FDA alert was prompted by two new cases: one patient who developed meningitis symptoms from a different steroid and a heart transplant patient who developed fungal infections after receiving a drug called cardioplegic solution, which is used during heart surgery.
Those cases are still under investigation, and FDA officials cautioned that it's possible the heart patients were infected by another source.
