title: [A case report of angina pectoris associated with hypereosinophilia in a patient on continuous ambulatory peritoneal dialysis (CAPD)].
abstract: We report a case of hypereosinophilia which was associated with the onset of anginal attacks. A 64-year-old man progressed to end-stage renal failure due to diabetic nephropathy, and was treated with continuous ambulatory peritoneal dialysis (CAPD). He had no past history of angina pectoris nor hypereosinophilia. Three weeks after the initiation of CAPD, the eosinophil count in peripheral blood increased (up to 4093/mm3). Two weeks later, he suffered from an anterior chest pain attack, and angina pectoris was diagnosed. As a result of treatment with isosorbide dinitrate and prednisolone, hypereosinophilia disappeared rapidly and repeated episodes of anginal attacks also disappeared. After an interval of 3 months, however, hypereosinophilia (up to 15190/mm3) and anginal attacks recurred. He underwent coronary angiography, in which no stenotic change was observed. The administration of prednisolone was effective in the treatment of these episodes. Although a close relationship between hypereosinophilia and anginal attack has been reported, it has not been known in CAPD patients as described here. Attention should be paid to these relationships in CAPD patients, because hypereosinophilia is frequently observed in maintenance peritoneal dialysis patients.
