Transfusion-related acute lung injury in a young woman with ectopic pregnancy - case report and literature review.

Abstract

Transfusion-related acute lung injury (TRALI) is a major cause of death associated with transfusion. Nevertheless it is still misdiagnosed and underreported. We present a case of this serious complication in order to make it more familiar to clinicians and indicate proper medical management, which is significant not only for the patients presenting TRALI symptoms but also for future recipients of blood components. A 32-year-old white woman with in-vitro fertilization in anamnesis was admitted to Department of Obstetrics and Gynecology because of abdominal pain. Ultrasonography examination revealed pathological mass in left adnexa. The patient underwent laparoscopic left salpingectomy. The following day she reported progressive pain in lower abdomen with signs of peritoneal irritation. Emergency laparotomy was performed and active bleeding from fallopian tube was stopped. Four units of red blood cells concentrate and six units of fresh frozen plasma were transfused. Within two hours of surgery acute respiratory distress symptoms occurred, bilateral infiltrates were found on chest X-ray. The patient responded to supportive treatment (oxygen therapy, dexamethasone, diuretics) and her state improved within 12 hours. Serological diagnostics revealed anti-HLA antibodies in one donor which reacted with patient's granulocytes. Clinical picture and anti-leukocyte antibodies detected in blood component allowed to identify the immune-mediated TRALI. Transfusion-related acute lung injury is a life-threatening complication of transfusion which manifests as non-cardiogenic pulmonary edema. Each suspected case of this syndrome should be reported to blood center in order to confirm the diagnosis and implement preventive measures (exclusion of implicated donor from further blood donation).
