Abstract


Introduction: Mushroom intoxication (MT) can lead to acute liver injury which may result in Mushroom intoxication‑related liver failure (M‑ALF) requiring liver transplantation (LT). In the present study, we want to share the experience of our institute regarding living‑donor LT (LDLT) due to mushroom poisoning.

Aim: The aim of this study is to identify the predictors of poor prognosis in patients with ALF secondary to mushroom intoxication requiring LDLT.

Materials and Methods: All patients with MT between 2008 and 2016 were evaluated. Demographics, symptoms, interval between symptoms and admission to our institute, laboratory data, model for end‑stage liver disease (MELD)/ pediatric end‑stage liver disease (PELD) scores, clinical course, and outcomes of supportive therapy and LT were evaluated. There were two groups in the study: Group A = responsive to supportive therapy (n = 9) versus Group B = unresponsive to supportive therapy (n = 9).

Results: During the study, a total of 18 patients were admitted with M‑ALF. Twelve (66.7%) of them were female, and the mean age was 39.9 ± 18.2 years. All of the nine patients in Group A fully recovered with supportive therapy. In Group B, one patient died during waiting period for LT and 8 patients received LDLT LDLT. Three of the eight patients who were transplanted died in the postoperative early period within postoperative 5 days. The patients in Group B had significantly higher MELD/PELD scores and encephalopathy rate than in Group A (P < 0.05). International normalized ratio (INR), bilirubin, ammonium levels, and platelet count were significantly different between groups (P < 0.05). The patients in Group B had significantly longer interval before admission to our institute (P < 0.05).

Conclusion: The presence of encephalopathy, higher MELD/PELD, INR, bilirubin, ammonium levels, and lower platelet count was related to poor prognosis in MT. LDLT provides a good therapeutic option in patients with M‑ALF. The time is a crucial factor in successful treatment of MT. Early admission to a tertiary referral center with expertise in LT results in a better prognosis and increased survival following M‑ALF.
