Acute Liver Failure Secondary to Anthocyanidin Use-A Case Report.

Drug-induced liver injury has become the main cause of acute liver failure (ALF). Injury may be dose-dependent or occur idiosyncratically. We report the case of a 37-year-old female patient admitted with grade 4 hepatic encephalopathy. Morosil use was initiated 30 days prior, and after 2 weeks, the case evolved with jaundice and diarrhea interspersed with constipation when the medication was discontinued. Morosil is a dry extract of the juice of red Moro oranges (Citrus species), grown in eastern Sicily (Italy). It is an important source of anthocyanidin pigments, which act as antioxidants and are used in the care and prevention of obesity, insulin resistance, hepatic steatosis, and cardiovascular diseases. According to the clinical picture and tests performed, the diagnosis of ALF was confirmed, by the criteria of Clichy and King's College. The patient was listed for liver transplantation as a priority, with the model for end stage liver disease (MELD) score: 41. Orthotopic liver transplantation was uneventfully performed using the Piggy-back technique. There are few reports in the literature of acute liver injury by other Citrus species, and we found no case reports of ALF related to the use of Morosil.

Validation of New York/California Score in the Preoperative Period of Liver Transplant for Hepatocellular Carcinoma at University of Campinas's Hospital.

Liver transplant is the main treatment for hepatocellular carcinoma and there is currently an important demand from patients waiting in transplant queues. Thus, it is extremely important to improve the criteria for selecting patients who will undergo transplant to mitigate graft loss and reduce cases of recurrence. Thus, it becomes necessary to use models, such as the New York/California (NYCA), that include alpha fetoprotein as a marker of recurrence and prognosis. The aim of this study was to assess whether the NYCA score correlated with the presence of tumor recurrence after transplant in patients undergoing orthotopic liver transplant at the Clinics Hospital of the University of Campinas. We had 214 patients undergoing liver transplant who met the inclusion Milan criteria. The age of the patients ranged from 34 to 77 years, with a median age of 61 years. The mean waiting time on the transplant list was 6.12 months. After calculating the NYCA score, it was possible to stratify 13 patients (6.1%) as high risk, 64 patients (29.9%) as medium risk, and 137 patients (64%) as low risk. Patients with recurrence had higher scores with a mean of 4 points in relapse and 2 points in the absence of relapse (P = .0011). Patients with recurrence had statistically higher high- and medium-risk scores (P = .0010). Therefore, the NYCA score was higher in patients with recurrence. Therefore, in this study, our findings suggest the possibility of using the NYCA score as an aid to detect patients with a higher risk of tumor recurrence.

Refinement of the Milan Criteria: Role of α-Fetoprotein In Liver Transplantation for Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the most common primary neoplasm of the liver, mainly secondary to cirrhosis caused by hepatitis C virus. Liver transplant (LT) is considered the best treatment because, in addition to removing the tumor, it also removes the underlying cirrhotic liver. The Milan criteria for LT have limitations because they do not consider the biological characteristics of the tumor. Thus, our objective was to evaluate the association of α-fetoprotein (AFP) levels before LT performed for HCC with recurrence of this tumor, and, based on the results, a new predictive model that combines the AFP values at the list entry with the usual criteria of tumor size and number of nodules was validated. In present study, the Score AFP model, we were able to correlate a greater occurrence of relapse with scores of 3 and 4 (P = .0001), indicating the usefulness of using AFP as a predictor of recurrence.

Validation of Metroticket Score in the Preoperative Period of Liver Transplantation for Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the sixth leading cause of cancer in the world, and liver transplant (LT) is a good therapeutic option in selected cases because it treats the neoplasm and the underlying disease. Recurrence after LT is usually aggressive and has low survival; thus, an adequate selection of recipients is ideal. The new models aim to assess the individual risk of HCC recurrence in patients undergoing LT and to improve post-LT survival. In this study, our aim was to assess the applicability of the "Metroticket" score, correlating it with our rates of recurrence and survival after LT. Overall survival at 5 years in our study differed from that in Metroticket 2.0 because that study did not consider only recurrence as the cause of death; our study evaluated only patients with recurrence, so we were able to validate the score as a predictor of greater tumor aggressiveness after LT.

GLP-1: 10-year follow-up after Roux-en-Y gastric bypass.

PURPOSE: Glucagon-like peptide-1 (GLP-1) is a hormone widely studied in the short-term postoperative follow-up of Roux-en-Y gastric bypass due to its elevation and association with improvement of the glucose metabolism, but there are few studies in 10 years after RYGB follow-up with the same patient. METHODS: Twenty morbidity obesity patients were submitted to RYGB; these patients were divided into two groups: normal glucose-tolerant morbidly obese patients (NGT) 11 patients and abnormal glucose metabolism morbidly obese patients (AGM) 9 patients. Oral glucose tolerance test (OGTT) was done during four different periods: T1 (first evaluation), T2 (pre-surgery), T3 (9 months after surgery) and T4 (10 years after surgery). RESULTS: Groups were matched for age and gender, and as NGT and AGM had BMI of 46.31 ± 5.03 kg/m2 and 50.87 ± 10.31 kg/m2. After 10 years of RYGB, they were obesity grade I with BMI for NGT 32.45 ± 4.99 kg/m2 and AGM 34.85 ± 4.46 kg/m2. Plasma glucose levels decreased NGT group at T4 period had a significant reduction at 120 min after OGTT for NGT 55.49 ± 17.15 mg/dL (p˂0.001). Insulin levels changed from T1 to T4 for the NGT group. GLP-1 curves were statistically different between the NGT and AGM groups. The AGM group had a higher mean for GLP-1 secretion at T4 period and at 30 min of OGTT 63.85 ± 37.98 pmol/L when compared to NGT 50.73 ± 24.82 pmol/L with AGM > NGT with p˂0.001. CONCLUSION: Evaluation of the same patient during 4 different periods shows that, even with weight regain, after 10-years of RYGB high levels of GLP-1 remained which can be associated with metabolic improvement especially at the NGT group.
