BACKGROUNDS: Antiphospholipid antibodies which are frquently found in systemic lupus erythematosus and primary antiphospholipid syndrome are associated with recurrent abortions and thromboembolism. In this study the authors investigated whether antiphospholipid antibodies are found in Graves disease, a representative organ-specific autoimmune disease and what is the clinical implication of the antiphospholipid antibodies if they appear in Graves disease. METHODS: Anticardiolipin antibody and lupus anticoagulant activity were measured in 57 untreated hyperthyroid Graves patients. 42 euthyroid patients with thyroid nodules served as controls. RESULTS: Eight of the 57 patients with Graves disease had anticardiolipin antibody which was significantly more frequent than in control group. Six of the eight patients who had anticardiolipin antibody had IgM type antibody and two had IgG type antibody. All their antibody activity declined with several months of antithyroid drug therapy and finally disappeared when the patients became euthyroid. Presence of anticardiolipin antibody had no relationship with clinical events such as spontaneous abrtion and thromboembolism. CONCLUSION: Anticardiolipin antibody is frequently found in patients with Graves disease. They seem to appear as an epiphenomenon of autoimmunity and they seem not to have any clinical implications.

The mechanism of development of pulmonary edema associated with -sympathomimetic agent is still not fully understood. 2-sympathomimetic drugs such as ritodrine, terbutaline, and fenoterol are widely used for the treatment of premature uterine contraction. We describe a case of pulmonary edema that occurred suddenly during Cesarean section in a previously healthy parturient, associated with ritodrine pretreatment for 5 days in an attempt to arrest preterm labor. Pulmonary edema was completely treated with mechanical ventilation and diuretic therapy.

Allogenic bone marrow chimera has been used to study the differentiation of donor-derived bone marrow cells under the recipient thymic environment, tolerance generaion between recipient and donor cells. We prepared H-2' to H-2 allogenic chimera by transfering bone marrow cells from H-2dmice to r-irradiated H-2k mice, and examined the differentiation ofthe bone marrow cells under allogenic environment. Complete reconstitution with H-2d+ phenotype cells in the thymus of the chimera mice was observed. However, the number of CD4- CD8+ cells dramatically decreased under the recipient thymic environment, CD8+ cells significantly reduced also in spleen and lymph node, compared with that of normal mice. Interestingly, we also observed coexistence of donor-derived cells (H-2k) and recipient derived cells (H-2d) in lymph node and spleen in the chimera. These results suggested that the decrease of CD4-CD8+ cells could be caused by r-irradiation by affecting the recipient thymic environment, and that in this chimera, tolerance between donor-derived cells and recipient-derived cells was maintained.
