[Early recurrent spontaneous abortion: How to take care in 2006?]

Abstract

More than 1% of the couples whishing children suffer from recurrent miscarriage, but investigations and treatment are not consensual. Most patients have several risk factors, and a minimum investigation of known factors has to be undertaken: karyotyping of the couple, hysteroscopy for searching uterine anatomic anomalies, evaluation for thrombophilias (anticardiolipin antibodies, lupus anticoagulant, protein C activity, Proteine S activity, factor V Leiden and factor II mutations, activated protein C resistance), antinuclear antibodies. Systemic diseases (like lupus) and endocrine abnormalities (like thyroid diseases and diabetes mellitus) have to be detected by clinical examination and questioning. No endocrine investigation is recommended, unless irregular menstruations or sterility. Research in recurrent pregnancy loss are conducted in new associated factors, such as skewed-X-chromosome inactivation, maternal HLA types, modifications in specific immune molecules and cells regulation. Therapeutic proposals are preimplantation genetic diagnosis in case of abnormal karyotiping, hysteroscopic surgery for septate uterus, aspirin plus heparin in antiphospholipid-positive patients, and aspirin plus corticosteroids in systemic lupus. Heparin seems to improve obstetrical prognosis for patients with congenital or acquired thrombophilias, but there are only few studies carried out on the subject. This new therapeutic approach should incite the patients with a negative medical appraisal to be referred to specialized consultations in order to include them in eventual clinical tests. Finally, empathic listening and psychological support are necessary in a pathology with multiple etiological factors.
