Resumen
Fecha de inicio: 1 de septiembre de 1992
Fecha en la que se inscribió al primer participante.PROTOCOL OUTLINE: This is a randomized, double-blind study. The first group receives intravenous immune globulin (IVIG) on days 1, 2, and 21; the second group receives an intravenous placebo on the same schedule. Patients in either group may receive IVIG (same dosage as first group) after day 42. Concurrent steroids and other immune globulin preparations are prohibited.
