Examples of "gestationis"
Gestational pemphigoid or pemphigoid gestationis (PG) is a dermatosis of pregnancy, being an autoimmune blistering skin disease that occurs during pregnancy, typically in the second or third trimester, and/or immediately following pregnancy. It was originally called herpes gestationis because of the blistering appearance, although it is not associated with the herpes virus.
DR4 is associated with extraarticularrheumatoid arthritis, hydralazine-induced female systemic lupus erythematosus, pemphigoid gestationis, pemphigus foliaceus, obstructive hypertrophic cardiomyopathy, IgA nephropathy, 'shared syndrome'-systemic sclerosis/rheumatoid arthritis and polymyalgia rheumatica.
Prurigo gestationis (also called "Besnier prurigo", "Early-onset prurigo of pregnancy," "Linear IgM dermatosis of pregnancy," "Papular dermatitis of pregnancy," "Prurigo of pregnancy", and "Spangler's papular dermatitis of pregnancy") is an eruption consisting of pruritic, excoriated papules of the proximal limbs and upper trunk, most often occurring between the 20th and 34th week of gestation.
Pathogenically, it is a Type II Hypersensitivity reaction where circulating complement-fixing IgG antibodies bind to an antigen (a 180-kDa protein, BP-180) in the hemidesmosomes (attach basal cells of epidermis to the basal lamina and hence to dermis) of the dermoepidermal junction (DEJ) , leading to blister formation as loss of hemidesmosomes causes the epidermis to separate from dermis. The immune response is even more highly restricted to the NC16A domain. The primary site of autoimmunity seems not to be the skin, but the placenta, as antibodies bind not only to the basement membrane zone of the epidermis, but also to that of chorionic and amniotic epitheli. Aberrant expression of MHC class II molecules on the chorionic villi suggests an allogenic immune reaction to a placental matrix antigen, thought to be of paternal origin .Recently, both IgA22 and IgE24 antibodies to either BP180 or BP230 have also been detected in pemphigoid gestationis.
