Epilepsy Does Not Affect Women’s Fertility

In women without a history of infertility or related disorders, the likelihood of conceiving and having a live birth is no different between individuals with or without epilepsy, according to a study published online ahead of print April 30 in JAMA Neurology. Researchers examined data from the Women With Epilepsy: Pregnancy Outcomes and Deliveries study to compare fertility rates between women with and without epilepsy. The primary outcome was the proportion of women who achieved pregnancy within 12 months after enrollment. Of the 197 participants, 142 were white. Mean age was 31.9 among the 89 women with epilepsy and 31.1 among the 108 control women. Among women with epilepsy, 60.7% achieved pregnancy, compared with 60.2% among controls. Median time to pregnancy was similar between groups.

FDA Approves Treatment for CIDP

The FDA has approved Hizentra (immune globulin subcutaneous [human] 20% liquid) as the first subcutaneous immunoglobulin (SCIg) for the treatment of chronic inflammatory demyelinating polyneuropathy (CIDP) as maintenance therapy to prevent relapse of neuromuscular disability and impairment. The approval was based on the phase III PATH study, which was the largest controlled clinical study of patients with CIDP to date. The percentage of patients experiencing CIDP relapse or withdrawal for any other reason during SCIg treatment was significantly lower with Hizentra (38.6% on low-dose Hizentra [0.2 g/kg weekly], 32.8% on high-dose Hizentra [0.4 g/kg weekly]) than with placebo (63.2%). Treated patients reported fewer systemic adverse reactions per infusion, compared with IVIg treatment (2.7% vs 9.8%, respectively). Approximately 93% of infusions caused no adverse reactions. Hizentra is marketed by CSL Behring.

Sauna Bathing Reduces Stroke Risk

Frequent sauna bathing is associated with a reduced risk of stroke, according to a study published online ahead of print May 2 in Neurology. Researchers assessed baseline habits of sauna bathing in 1,628 adults between ages 53 and 74 (mean age, 62.7) without a known history of stroke. The following sauna bathing frequency groups were defined: once per week, two to three times per week, and four to seven times per week. During a median follow-up of 14.9 years, 155 incident stroke events were recorded. Compared with people who took one sauna bath per week, the risk of stroke was 14% lower among people with two to three sessions and 61% lower among people with four to seven sessions. Controlling for stroke risk factors did not alter the association.
