[Dermatological diseases influenced by pregnancy].

Systemic lupus erythematosus Pregnancy can trigger-off or worsen the disease (60% of lupus flares). The renal damage and hypertension are important prognostic factors. Regarding the foetus, there is a 60% risk of prematurity. The risk of neonatal lupus is basically related to the presence of anti-Ro-SSA and anti-La-SSB antibodies and cannot not be foreseen. Multi-disciplinary surveillance is a necessity for any woman suffering from lupus and wishing to become pregnant. Other connective disorders Pregnancy is rare during scleroderma and has no influence on its progression except in the case of renal damage. Regarding dermatopolymyositis, pregnancy, which is rare, might trigger-off or worsen the disease. Bullous diseases Porphyria may be triggered-off or worsened during pregnancy. The various forms of pemphigus may appear or be enhanced by pregnancy. Various affections The influence of sarcoidosis on pregnancy is negligible. Complications are possible in patients exhibiting a type I or IV Ehlers-Danlos syndrome. Pregnancy can enhance the vascular complications of a pseudoxanthoma elasticum. An exacerbation is possible in the case of a type I neurofibromatosis. Progression varies in the case of psoriasis, atypical dermatitis, acne and Behçet's disease. Genital infections are frequent during pregnancy and often represent a risk for the infant (vaginal candidosis, viral condyloma, gonococci, herpes infection). Varicella The risk of severe neonatal varicella is high when the disease appears in the mother just before or after delivery.
