Acute Pain Transfusion Reaction: A Case Report.

Transfusion-related adverse events involving packed red blood cells (PRBCs) and fresh frozen plasma (FFP) are not unusual. Reactions can happen at any time during the transfusion, as well as hours or days later. An acute pain transfusion reaction (APTR) is defined as sudden, intense joint pain, usually in the back and trunk, that appears right after transfusion after all other potential causes of transfusion reactions have been eliminated. The present article discusses two similar cases. A 38-year-old female presented with complaints of right-sided headache and photophobia for four days, associated with nausea, vomiting, and vertigo. She was evaluated for a migraine headache. Due to anemia, a one-unit PRBC was requested. After pre-transfusion testing, a one-unit non-leuko-reduced, coombs cross-match compatible B-positive packed red blood cell (PRBC) was issued and transfused. During the transfusion, the patient complained of chest pain. The transfusion was stopped. Her vitals did not vary much from the baseline. No other symptoms were present at that time. A 69-year-old female presented with complaints of vomiting, abdominal pain, and black tarry stool for a one-month duration. On evaluation, she was diagnosed with adenocarcinoma of the stomach. Given the increased prothrombin time/international normalized ratio (PT/INR) of 1.8, four-units of fresh frozen plasma (FFP) was requested, which was issued after performing minor cross-match compatibility. After five minutes of transfusion, she complained of severe pain at the transfusion site with chills and rigors. The transfusion was stopped. There was no change in the vitals of the patient from baseline. A complete workup was done to rule out other transfusion reactions in both cases. Thus, these patients experienced what is known as an acute pain transfusion reaction. APTR is typically self-limited and requires treatment of symptoms with pain control, supplemental oxygen, and emotional support. In both cases, supportive treatments were enough to control the pain symptoms of the patients.
