  • Title: Cerebral vein thrombosis and the contraceptive pill in paroxysmal nocturnal haemoglobinuria.
    Author: Stirling ML, Lenton RJ, Sumerling MD.
    Journal: Scott Med J; 1980 Jul; 25(3):243-4. PubMed ID: 7444435.
    Abstract:
    A young woman who developed a cerebral venous thrombosis shortly after commencement of an oral contraceptive preparation was subsequently found to have paroxysmal nocturnal haemoglobinuria. The aetiology of thrombotic complications in this condition is discussed, with particular reference to the additional risk factor of the contraceptive pill in this case. A case of a young women with paroxysmal nocturnal hemoglobin (PNH) who developed thrombosis of the cerebral veins after beginning a regimen of oral contraceptives is presented. She was 24 years old and presented with a 3-week history of frontal headache, neck stiffness, paraesthesiae of both arms, and weakness of the left leg. She had begun use of Microgynon 2 months before presentation, but had discontinued use when symptoms began. Hematological studies showed a shortened partial thromboplastin time, high fibrinogen and factor VIII levels, and prlonged euglobulin clot lysis time. Though this patient had a history of coagulation difficulties, it was not until after taking the estrogen-containing contraceptive preparation that PNH developed. The mechanism of thrombosis may be related to the liberation of thromboplastic material from hemolysed erythrocytes and to interaction between complement-sensitive platelets and complement components in plasma. It is suggested that the estrogen augmented the previously existing thrombotic condition in this patient, and that administration of estrogen-containing preparations should not occur in women with thrombotic disorders.
