Postpartum Treatment With Immunoglobulin Does Not Prevent Relapses of Multiple Sclerosis in the Mother.

Multiple sclerosis (MS) is a chronic, neurological, immune-mediated disease that can worsen in the postpartum period. There is no consensus on the use of immunoglobulin for prevention of disease relapses after delivery. We have shown that the controversial beneficial effect of immunoglobulin given immediately after birth could not be observed in patients with MS.

Multiple sclerosis in South America: month of birth in different latitudes does not seem to interfere with the prevalence or progression of the disease.

Objective: To assess whether the month of birth in different latitudes of South America might influence the presence or severity of multiple sclerosis (MS) later in life.

Methods: Neurologists in four South American countries working at MS units collected data on their patients' month of birth, gender, age, and disease progression.

Results: Analysis of data from 1207 MS patients and 1207 control subjects did not show any significant variation in the month of birth regarding the prevalence of MS in four latitude bands (0-10; 11-20; 21-30; and 31-40 degrees).
