Antiphospholipid syndrome (APS) is an entity characterized by recurrent thrombotic events and may occur spontaneously or in the context of systemic lupus erythematosus (SLE). We describe an English Canadian family in whom the propositus, a woman with Graves' disease and SLE, was found to have a lupus anticoagulant and anticardiolipin antibody (aCL). A brother with deep vein thrombosis, pulmonary emboli, bilateral adrenal hemorrhage and thrombocytopenia, circulating anticoagulant and aCL had a positive antinuclear antibody and Coombs' test, but no other features of SLE. Fourteen members of 3 generations of this family underwent clinical assessments, serological testing and HLA typing. The propositus' mother had a family history of autoimmune thyroid disease and the father had aCL, but was asymptomatic. The thyroid disease and the SLE were associated with HLA-B8, DR3 haplotype. The aCL and the anticoagulant were associated with HLA-B60, DR4 haplotype. Both these haplotypes were present in the propositus. Among the other 4 carriers of the haplotype B60, DR4, 3 demonstrated significant titers of aCL. Our findings support the reported association between APS and the HLA haplotype DR4 in patients of English descent with SLE.

Although a few reports in recent years have suggested that patients with antiphospholipid antibodies (aPL) are prone to developing primary anetoderma (PA), it is still unclear how often aPL are detected in unselected PA patients. We studied nine consecutive PA patients for the presence of autoimmune antibodies and disorders in general and the presence of aPL in particular. Six of the nine patients had clinical evidence of associated autoimmune disorders (Graves'disease and autoimmune haemolysis in one, systemic scleroderma in one, Hashimoto's thyroiditis in one, alopecia areata in one) and/or signs of hypercoagulability (recurrent fetal loss in two, recurrent stokes in one, recurrent deep vein thrombosis in one). In four ofthese six patients the onset of PA preceded these signs. Positive aPL was found in all: anticardiolipin (aCL) in six, anti-beta2-glycoprotein-I (a(beta)2GPI) in six and lupus anticoagulant (LAC) in four. The most frequent isotype was IgA. Among other autoantibodies found the most frequently was antinuclear antibodies. Four ofthe nine patients fulfilled the criteria for antiphospholipid syndrome (APS). It is concluded that PA is an important cutaneous sign for autoimmune disorders in general and the presence of aPL in particular. Hence, the work-up of these patients should include testing for LAC as well as for all different isotypes ofaCL and a(beta)2GPI. We recommend that PA be added to the list of the cutaneous manifestations of APS.

The article describes a case of Graves' disease treated with methimazole and examines the influence of methimazole-induced alterations of thyroid hormone concentrations during warfarin therapy. A 22-year-old woman presented at our endocrinology outpatient clinic with palpitations, sweating, fatigue, tremors, and diarrhea. She had a pain in her right leg and had difficulty walking. Her thyroid profile was consistent with hyperthyroidism. The patient was treated with warfarin 5 mg once a day for deep vein thrombosis for 2 days. Since a therapeutic range of International Normalized Ratio levels could not be achieved, methimazole was stopped due to drug-drug interaction. Lithium was started instead. A euthyroid state was obtained in 2 weeks together with a therapeutic International Normalized Ratio level. Interactions between warfarin and drugs that alter thyroid hormone concentrations have been reported; however, the extent and significance of the interaction between methimazole and warfarin have been inadequately described. Concomitant therapy with warfarin and antithyroid drugs should be managed by frequent monitoring of both thyroid function and the International Normalized Ratio. Lithium is employed only to provide temporary control of thyrotoxicosis in patients who cannot take thionamide and iodide. The administration of lithium alone or in combination with other drugs is shown to be an effective method of controlling hyperthyroidism when conventional antithyroid drugs show adverse effects or become insufficient. When warfarins are used together with antithyroid medications, adequate anticoagulation may not be obtained due to drug-drug interactions. Lithium can be an alternative drug for antithyroid medication in patients on warfarin therapy.
