Anaphylaxis Complicating Graft Reperfusion During Orthotopic Liver Transplantation: A Case Report
ABSTRACT Hemodynamic instability may occur during liver transplantation especially following unclamping the portal vein. A period of hypotension (postreperfusion syndrome) is usually responsive to treatment with fluids, calcium, sodium bicarbonate, and vasoactive drugs, but if hypotension persists, other causes must be sought out. In this report, we present a case in which anaphylaxis, most likely due to a component of the University of Wisconsin preservation solution, occurred coincident with liver reperfusion and severely exacerbated reperfusion hemodynamic instability. To our knowledge, this is the first report of anaphylaxis at the time of reperfusion and may provide an explanation for cases of vasoplegic syndrome associated with graft reperfusion.

ABSTRACT: BACKGROUND: Cellular therapy after organ transplantation is emerging as an intriguing strategy to achieve dose reduction of classical immunosuppressive pharmacotherapy. Here, we introduce a new scoring system to assess treatment-emergent adverse events (TEAEs) of adherent stem cell therapies in the clinical setting of allogeneic liver transplantation (for example, the MiSOT-I trial Eudract CT: 200901779525). METHODS: The score consists of three independent modalities (set of parameters) that focus on clinically relevant events early after intravenous or intraportal stem cell infusion: pulmonary toxicity, intraportal-infusional toxicity, and systemic toxicity. For each modality, values between 0 (no TEAE) and 3 (severe TEAE) were defined. The score was validated retrospectively on a cohort of n=187 recipients of liver allografts not receiving investigational cell therapy between July 2004 and December 2010. These patients represent a control population for further trials. Score values were calculated for days 1, 4, and 10 after liver transplantation. RESULTS: Grade 3 events were most commonly related to the pulmonary system (3.5% of study cohort on day 4). Almost no systemic-related TEAEs were observed during the study period. The relative frequency of grade 3 events never exceeded 5% over all modalities and time points. A subgroup analysis for grade 3 patients provided no descriptors associated with severe TEAEs. CONCLUSION: The MiSOT-I score provides an assessment tool to score specific adverse events that may occur after adherent stem cell therapy in the clinical setting of organ transplantation and is thus a helpful tool to conduct a safety study.Trials 11/2012; 13(1):211.

ABSTRACT: We present a case in which anaphylaxis on hepatic reperfusion during liver transplantation presented only with hypotension and coagulopathy. There were no cutaneous manifestations or clinical features distinguishing anaphylaxis from postreperfusion syndrome. The recipient regularly consumed seafood, and the organ donor died of anaphylaxis to shellfish. The trigger for anaphylaxis was postulated to be passive transfer of immunoglobulin to the recipient. Anesthesiologists should be notified of donor factors to anticipate anaphylaxis. In this report, we discuss coagulopathy of anaphylaxis and contrast it with disseminated intravascular coagulation.Anesthesia and analgesia 06/2012; 115(3):522-5.
