ABSTRACT

Acute-on chronic liver failure (ACLF) has been an intensively debated topic mainly due to the lack of a unified definition and diagnostic criteria. The growing number of publications describing the mechanisms of ACLF development, the progression of the disease, outcomes and treatment has contributed to a better understanding of the disease, however, it has also sparked the debate about this condition. As an attempt to provide medical professionals with a more uniform definition that could be applied to our population, the first Mexican consensus was performed by a panel of experts in the area of hepatology in Mexico. We used the most relevant and impactful publications along with the clinical and research experience of the consensus participants. The consensus was led by 4 coordinators who provided the most relevant bibliography by doing an exhaustive search on the topic. The entire bibliography was made available to the members of the consensus for consultation at any time during the process and six working groups were formed to develop the following sections: 1.- Generalities, definitions, and criteria, 2.- Pathophysiology of cirrhosis, 3.- Genetics in ACLF, 4.- Clinical manifestations, 5.- Liver transplantation in ACLF, 6.- Other treatments.

ABSTRACT

BACKGROUND AND AIMS: The IL28B single nucleotide polymorphism (SNP) rs12979860 is a major predictor of treatment outcomes in hepatitis C virus (HCV) infection, but its distribution widely varies among populations and ethnicities. We undertook this study to investigate the distribution of IL28B SNP rs12979860 in Mexican patients with HCV infection and to assess its usefulness in predicting response to pegylated interferon-alpha and ribavirin (PegIFN-α/RVB) therapy. METHODS: Three hundred and fifty patients with chronic HCV infection were studied. The frequency of sustained virologic response (SVR), non-responders and relapses following a course of standard therapy was longitudinally assessed in 295 of these patients. IL28B SNP rs12979860 was genotyped from genomic DNA using real-time RT-PCR. The number needed to treat (NNT) to achieve a SVR was calculated. RESULTS: Seventy six (22%) patients were CC homozygous, 210 (60%) were heterozygous and 64 (18%) showed TT homozygosity for the IL28B SNP rs12979860. After a standard course of PegIFN-α/RVB, 69% of patients with the CC genotype, 46% of the heterozygous group and 38% of those with the TT genotype (p = 0.001) achieved a SVR. Conversely, the percentage of non-responders was 15, 43, and 48% (p <0.0001), respectively. The NNT to achieve a SVR was strongly influenced by the IL28B rs12979860 genotype and ranged from 2-10. CONCLUSIONS: The IL-28B rs12979860 CC genotype was found in 22% of Mexican patients chronically infected by HCV. Genotyping IL28B SNP rs12979860 is useful to predict the response to a standard regimen with PegIFN-α/RVB, especially in those infected with HCV genotype 1.
