RESUMO
BACKGROUND: Several years ago the International Autoimmune Hepatitis Group simplified the previous revised original scoring system for diagnosis of autoimmune hepatitis (AIH) into a scoring system based on only four instead of 13 parameters. OBJECTIVE: We aimed to evaluate the suitability of the simplified AIH score for diagnosis of AIH in a German cohort with chronic liver diseases. METHODS: In this retrospective single-center study, we compared the accuracy of both AIH scores in 70 patients with AIH and 211 patients with chronic liver diseases (PBC (n = 52), PSC (n = 27), NASH (n = 67), DILI (n = 15), CHB/C (n = 50)). Sensitivity, specificity and predictability of each scoring system were calculated. RESULTS: Using the simplified AIH score, the sensitivity and specificity of detecting a probable AIH (scores ≥ 6) were 96% and 97% with a positive and negative predictive value of 92% and 99%, respectively. For diagnosis of definite AIH (scores ≥ 7), the sensitivity and specificity were 43% and 100% with a positive and negative predictive value of 97% and 84%, respectively. The concordance with the revised original criteria was 63%. The specificity for excluding AIH was excellent in both scoring system. CONCLUSION: The simplified diagnostic criteria allow a reliable diagnosis of AIH in a German cohort.
RESUMO
BACKGROUND: Colorectal cancer is the third most common cancer and a major cause of morbidity and mortality worldwide. Adjuvant chemotherapy is considered the standard of care in patients with UICC stage III colon cancer after R0 resection. Adjuvant therapy was not shown to be beneficial in patients with UICC stage II colon cancer. However, there is an ongoing discussion as to whether adjuvant chemotherapy may be beneficial for a subgroup of UICC II patients in a "high-risk situation" (such as T4). METHODS: We investigated a Bavarian population-based (2.1 million inhabitants) cohort of 1937 patients with UICC II CRC treated between 2002 and 2012 in regard of the benefit of adjuvant chemotherapy for large (T4) tumors. Patients older than 80 years of age were excluded. Of 1937 patients, 240 had a T4 tumor (12%); 77 of all T4 patients received postoperative chemotherapy (33%). Kaplan-Meier analysis and Cox regression models were used for survival analyses. RESULTS: Patients with a T4 tumor who received postoperative chemotherapy had a highly significant survival benefit in respect of overall survival (p<0.001) and recurrence-free survival (p=0.008). However, no difference was observed between oxaliplatin-containing and non-oxaliplatin-containing treatment regimens. G2 and G3 tumors were found to particularly benefit from adjuvant treatment. Chemotherapy, age at diagnosis, and tumor grading remained independent risk factors in the multivariate cox regression analysis. CONCLUSION: Our retrospective study demonstrated the significant benefit of adjuvant chemotherapy in the T4 subgroup of patients with UICC II colon cancer. Our data suggest that adjuvant chemotherapy should be seriously considered in these patients.

Dual and triple infections with hepatitis virus C (HCV), B (HBV) and D (HDV) frequently lead to severe liver damage. Hereby we describe a 38-year-old Caucasian male coinfected with HCV (genotype 3a), HBV [positive hepatitis B surface antigen (HbsAg) and antibody to hepatitis B core antigen; negative hepatitis B e antigen (HbeAg) and antibody to hepatitis B e antigen (anti-HBe)] and HDV. Laboratory diagnostics revealed increased liver enzymes and histological examination of the liver showed signs of fibrosis with moderate inflammation. On therapy with pegIFN-α2b and ribavirin HCV-RNA was undetectable at week 8. After week 24 the antiviral therapy was stopped because of a HBs-seroconversion, the loss of HbeAg and the detection of anti-HBe. Furthermore the HCV-RNA was negative. Six months after successful treatment of the triple-infection, HCV- and HDV-RNA and HbsAg remained negative and the liver enzymes had been completely normalized. In conclusion, pegylated-interferon plus ribavirin may be an effective therapy for HCV, HBV and HDV-coinfected patients.
RESUMO
OBJECTIVE: Alcohol-toxic liver cirrhosis (ALC) is one of the main indications for liver transplantation (LT). The aim of the study is to define predictors for alcohol recidivism and to identify the outcome and quality of life of such patients. MATERIAL AND METHODS: From March 2003 to July 2009, 226 patients underwent LT in our centre. In 53% liver cirrhosis was caused by alcohol abuse (sole/cofactor). Outcome and alcohol recidivism were assessed using patients' records, laboratory tests and interviews (patient, family members and family doctor). Furthermore, patients received an SF-36 quality of life and a self-designed questionnaire anonymously. RESULTS: Mean follow-up after LT was 31 + 23 months. The 5-year survival rate after LT in patients with ALC was significantly better compared to patients with other indications (78 vs. 64%; p = 0.016). Quality of life of both patient groups was comparable. After LT, alcohol recidivism rate was 16%. Patients with an alcohol abstinence of <3 months before LT had a significantly higher (p = 0.012) rate of alcohol recidivism in comparison to those with an abstinence of >3 months. Another predictor for alcohol recidivism was the patients' non-acceptance of having an alcohol problem before LT (p = 0.001). CONCLUSIONS: ALC is a good indication for LT. An alcohol abstinence of <3 months before LT and a non-acceptance of having an alcohol problem are strong predictors for alcohol recidivism after LT.

BACKGROUND: Most patients with high MELD scores have impaired renal function prior to transplantation. PATIENT AND METHODS: A retrospective case control study was conducted with initial low immunosuppression, which was increased when patients rejected or were clinically stable beyond day 30 ('bottom-up'). RESULTS: Thirty patients with impaired renal function were included. Fifteen were treated with de novo cyclosporine A (CsA; group A), and 15 had 'bottom-up' immunosuppression (group B). Baseline renal function was similar: serum creatinine (SCr) median 1.8 mg/dl (range: 1.5-4.0 mg/dl; group A) versus 2.4 mg/dl (range: 1.5-4.0 mg/dl; group B; p = 0.24). The requirement for renal replacement therapy was significantly lower in group B (p = 0.032). Ten received 'bottom-up' immunosuppression [4 CsA/1 sirolimus (Sir) 'on demand' after rejection, 5 Sir (stable)] beyond day 30. By months 6 and 12 (1.6 mg/dl vs. 1.2 mg/dl), SCr values were significantly better in group B (p = 0.006). Renal function in group B did not differ between patients receiving CsA or Sir. Overall complication rates, survival and biopsy-proven acute rejection were similar, although BANFF scores were higher in group B (p = 0.004). CONCLUSION: Successful implementation of 'bottom-up' immunosuppression in liver transplant recipients with high lab-MELD scores and renal dysfunction at the time of transplantation has the potential to substantially improve short- and long-term outcomes.
