Additional Octreotide Therapy to Sirolimus Achieved a Decrease in Sirolimus-refractory Chylous Effusion Complicated with Lymphangioleiomyomatosis

抄録

Recently, sirolimus, an inhibitor of mammalian target of rapamycin, was reported to decrease chylous effusion in patients with lymphangioleimyomatosis (LAM). We herein report a case of a 34-year-old woman with LAM who developed refractory chylothorax and chylous ascites during sirolimus therapy. In this case, to reduce chylous effusion, we administered octreotide, which is often used to control postoperative chylous effusion, in addition to the sirolimus therapy. This combination therapy reduced the chylothorax and chylous ascites. For patients with LAM, octreotide therapy in addition to sirolimus may be effective for treating sirolimus-refractory chylous effusion.
