Refractory pemphigoid gestationis postpartum

Pemphigoid Gestationis - Case Report and Review of Literature

Pemphigoid gestationis (PG) is a rare autoimmune bullous skin disorder which usually presents with intense pruritus and urticarial lesions that may evolve into vesicles and tense blisters. In majority of patients, it starts in the second or third trimester of pregnancy and resolves spontaneously after delivery. Lesions appear in the periumbilical area in 90% of patients and rapidly spread centrifugally to other parts of the body. The diagnosis needs to be confirmed by direct immunofluorescence test (DIF) with indirect immunofluorescence test (IIF), ELISA and immunoblot techniques playing role in diagnosis and/or monitoring antibodies level. Mild symptoms of PG can be treated with topical therapy only, but in severe course of the disease the treatment may be escalated to oral corticosteroids. We present an unusual case of PG started 2 weeks after delivery with an updated overview on the epidemiology, pathology, clinical picture, treatment, and complications of the disease.

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.

Gestational pemphigoid

Gestational pemphigoid (pemphigoid gestationis, PG) is a rare autoimmune skin disorder occurring characteristically during pregnancy. Autoantibodies against placental BP180 (also known as BPAG2 or collagen XVII) cause damage to the skin basement membrane, resulting in severe itching and blistering rash over the body and the extremities. The diagnosis of PG is confirmed by immunofluorescence analysis of a skin biopsy, while serum levels of pemphigoid antigen BP180 antibody can be used to assess disease activity. PG with mild symptoms can be treated with topical corticosteroids, while oral corticosteroids are the mainstay in treatment of severe PG. PG usually flares up at the time of delivery, and resolves spontaneously shortly after. However, relapses in subsequent pregnancies are common. As PG has been linked to the risk of prematurity and fetal growth restriction, prenatal monitoring jointly by a dermatologist and an obstetrician is recommended. Mothers should also be informed of the potential risk of re-activation of the disease in subsequent pregnancies and during hormonal contraception.

Suspicion of pulmonary embolism during treatment of pemphigoid gestationis

Pemphigoid gestationis (PG), first described in 1872 by Laws Milton, is a rare autoimmune bullous disease of pregnancy and puerperium. Pemphigoid gestationis has been estimated to occur in 1: 50 000 pregnancies and usually presents in the second or third trimester with exacerbation after partum. This disease is caused by circulating IgG1 immunoglobulin against hemidesmosomal protein bullous pemphigoid BP180 (BPAG2) type XVII collagen and less frequently BP230. We present a case of pemphigoid gestationis in primigravida with complications during treatment due to the suspicion of pulmonary embolism.
