Hepamet Fibrosis Score in Nonalcoholic Fatty Liver Disease Patients in Mexico: Lower than Expected Positive Predictive Value.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) has been associated with different negative outcomes in the presence of advanced fibrosis. The Hepamet Fibrosis Score (HFS), a recently described noninvasive score, has shown excellent performance for the detection of advanced fibrosis. The aim of this study was to assess its performance in a Mexican population with NAFLD. METHODS: This was a retrospective cross-sectional study performed in 222 patients with biopsy-proven NAFLD, of whom 33(14%) had advanced fibrosis. We retrieved clinical data from each patient's medical record to compute the HFS, the NAFLD Fibrosis Score (NFS), and the Fibrosis-4 (FIB-4), and assess their performance. RESULTS: When considering the models as continuous variables, the area under the receiving operating characteristics curve of the HFS(0.758) was not different from that of the NFS(0.669, p = 0.09) or FIB-4(0.796, p = 0.1). The HFS had a sensitivity, specificity, positive and negative predictive values of 76.7% (95% CI 57.7-90.1), 90.1% (95% CI 85-93.9), 36.7% (95% CI 19.9-56.1), and 94.3% (95% CI 88.5-97.7), respectively. Indeterminate results (i.e., gray area) were more common with FIB-4 and HFS when compared with NFS [139(63%) and 122(55%) vs 80(36%), p < 0.001]. The variables that were associated with misclassification using the HFS were diabetes [OR 3.40 (95% CI 1.42-8.10), p = 0.006] and age [OR 1.06 (95% CI 1.01-1.11), p = 0.01]. CONCLUSION: The HFS showed sensitivity and specificity similar to that reported in the original publication; however, the positive predictive value was 36.7% at a pretest probability of 14%. The role of the HFS in prospective studies and in combination with other methods should be further explored.

Depression in cirrhosis - a prospective evaluation of the prevalence, predictors and development of a screening nomogram.

BACKGROUND: Depression is associated with substantial morbidity and mortality in cirrhosis, but is underdiagnosed and undertreated. AIMS: Using the Mini International Neuropsychiatric Interview (MINI) as a gold-standard, to determine prevalence, predictors, and outcomes of depression, and to develop a screening nomogram for use in cirrhosis patients. METHODS: Cirrhotic outpatients 18-80 years of age, not on anti-depressants, were consecutively recruited from liver clinics at three tertiary care hospitals. Baseline health-related quality of life (HRQoL) and frailty were determined by the chronic liver disease questionnaire, EQ-VAS, Clinical Frailty Scale and Fried Frailty Criteria. Depression was identified using the MINI and participants were followed up to 6 months to determine unplanned hospitalization/death. RESULTS: Of 305 patients, 62% were male; mean age 55(10) years; mean MELD 12.5(5), 61% Child Pugh B/C. Prevalence of depression 18% by MINI. Patients with depression had lower baseline HRQoL and higher frailty scores. Five independently predictive factors were used to develop a clinical nomogram for the diagnosis of clinical depression. These included three Hospital Anxiety and Depression Screening tool variables: "I have lost interest in my appearance" (adjusted odds ratio [aOR] 2.2, P = 0.006), "I look forward with enjoyment to things" (aOR 2.0, P = 0.02), "I feel cheerful" (aOR 2.8, P = 0.002), and two demographic variables: younger age (aOR 0.92, P = 0.001) and not being married or in a common-law relationship (aOR 0.30, P = 0.008). CONCLUSIONS: Depression is common in patients with cirrhosis. It has a significant impact on HRQoL and functional status. The developed clinical nomogram is promising for the rapid screening of depression in patients with cirrhosis.

Management of Viral Hepatitis in Solid Organ Transplant Recipients.

With potent nucleos(t)ide analogue (NA) therapy, hepatitis B virus (HBV) is now an uncommon indication for liver transplant (LT) in North America. NA therapy, with or without hepatitis B immunoglobulin, results in low recurrence rates and excellent outcomes after LT. Direct-acting antiviral therapy for hepatitis C virus (HCV), results in cure in most patients, either before or after transplant. There are now descriptions of good clinical outcomes of transplant from HBV and HCV infected donors, as treatments are so effective and well tolerated. Hepatitis E virus in transplantation requires a high suspicion to diagnose and optimal therapy remains incompletely defined.
