Herpes Gestationis after Ovodonation: Is Placenta the only Target of the Immune Reaction?

Treatment of Autoimmune Bullous Diseases During Pregnancy and Lactation: A Review Focusing on Pemphigus and Pemphigoid Gestationis

Pregnancy may induce the onset or exacerbation of autoimmune bullous diseases such as pemphigus or pemphigoid gestationis. A shift toward T helper (Th) 2 immune response and the influence of hormonal changes have been evoked as possible triggering factors. Therapeutic management of this setting of patients may represent a challenge, mainly due to safety concerns of some immunosuppressive drugs during pregnancy and lactation. In this narrative review, we provided a comprehensive overview of the therapeutic management of autoimmune bullous diseases in pregnant and breastfeeding women, focusing on pemphigus and pemphigoid gestationis.

[Pemphigoid gestationis after egg donation : A case report]

Pemphigoid gestationis (PG) is a blistering autoimmune skin disease, typically occurring in the second and third trimester of pregnancy. Aberrant expression of major histocompatibility complex (MHC) class II molecules on the chorionic villi seems to lead to antibody production against bullous pemphigoid (BP)-180. We report a case of PG in a woman whose pregnancy was achieved using egg donation. Since the entire fetal genome is allogeneic to the mother, augmented immune reaction in egg-donated pregnancies appears to trigger the occurrence of PG.
