[The effects of thromboxane A2 synthetase inhibitor on chronic rejection of kidney transplantation].
There has been no useful treatments for chronic vascular rejection (CVR) after kidney transplantation until now. Recently, however, some reports have suggested that the thromboxane A2 synthetase inhibitor, OKY-046, is useful in reducing proteinuria in nephrotic syndrome and preventing progression of CVR. Five patients with CVR (serum creatinine range: 1.7-2.6 mg/dl) were treated with OKY-046 for over one year and the effect of OKY-046 was evaluated. One patient developed acute rejection and another renal hypertension during this study. Except for the cases of acute rejection and renal hypertension, serum creatinine slightly decreased in 1 case and remained unchanged in 2 cases. Urinary excretion of protein and thromboxane B2 decreased significantly but prostaglandin E2 did not change in the treatment of the deterioration with OKY-046. We concluded that OKY-046 was effective in preventing graft function and decreasing urinary protein excretion in kidney transplant recipients with CVR.
