title: Significance of values of thyrotropin binding inhibitor immunoglobulins and appearance of intrathyroidal lymphocytes at subtotal thyroidectomy for Graves' disease.
abstract: This study was undertaken to investigate whether thyrotropin binding inhibitor immunoglobulins (TBII) values at and after subtotal thyroidectomy correlated with the outcome or the histologic grade applied to the appearance of intrathyroidal lymphocytes at the time of surgical treatment. In addition, the main reason for the study was to determine whether or not it was possible to predict the outcome after the operation by the data obtained. There was no relation between the TBII results and the grade of the appearance of intrathyroidal lymphocytes at the time of operation or the TBII postoperative results (whether positive or negative) and the final outcome. However, it was of interest that patients with a recurrence of hyperthyroidism had the TBII values of more than 50 percent at the time of surgical treatment, and also manifested continuously positive TBII values after the operation. They also had moderate grades of lymphocytic infiltration and lymph follicle formation in the surgical specimen. It seemed impossible to predict the outcome of each instance in accordance with TBII values and the grade of the appearance of intrathyroidal lymphocytes at the time of the operation. However, it might be possible to predict at least the recurrence of hyperthyroidism by the consideration of changes of TBII values postoperatively.
