Researchers have found that people who receive intravenous immunoglobulin seem to have an increased risk of a stroke.
Intravenous immunoglobulin (IVIG) is a common treatment for a wide range of neurologic and blood disorders. There have been sporadic reports of stroke linked to IVIG since the mid 1980s. Wake Forest University School of Medicine now reports on the largest collection of cases of IVIG linked stroke.
In a group of 16 patients, 14 experienced a stroke either during or within 24 hours of IVIG treatment. In the others, the stroke occurred within four days of treatment. Fifteen out of sixteen had one or more risk factors for stroke, such as high blood pressure or diabetes. The overall risk of IVIG linked stroke is very small – just 0.6 per cent of patients receiving the treatment in a four year period, say the researchers. But this study suggests it is important to identify those most at risk of stroke before giving them IVIG treatment.
