RESUMO
The major function of platelets is to contribute to hemostasis. If an impairment in their production and/or function occurs, abnormal bleeding can develop. An 18-year-old male presented to our hospital after four episodes of hematemesis. His medical history was relevant for Glanzmann thrombasthenia diagnosed during early childhood. On initial examination, he appeared pale and with normal blood pressure. His complete blood count included a hemoglobin concentration of 11.0 g/dL, additional laboratory tests were within the normal ranges. The initial approach consisted of a high dose of proton pump inhibitors. Hours later, esophagogastroduodenoscopy revealed diffuse oozing bleeding from gastric mucosa with no other visible lesions such as peptic ulcers or varices.

Cirrhosis is characterised by a prolonged asymptomatic period in which the inflammation persists, increasing as the disease progresses. Characteristic of this is the increase in pro-inflammatory cytokines and pro-oxidant molecules which are determining factors in the development of multiple organ dysfunction. In the early development of cirrhosis, splanchnic arterial vasodilation, activation of vasoconstrictor systems (renin-angiotensin-aldosterone) and the sympathetic nervous system (noradrenaline) bring about bacterial translocation and systemic dissemination via portal circulation of bacterial products, and molecular patterns associated with damage, which exacerbate the systemic inflammation present in the patient with cirrhosis. Albumin is a molecule that undergoes structural and functional changes as liver damage progresses, affecting its antioxidant, immunomodulatory, oncotic and endothelial stabilising properties. Our knowledge of the properties of albumin reveals a molecule with multiple treatment options in patients with cirrhosis, from the compensated then decompensated phases to multiple organ dysfunction. Its recognised uses in spontaneous bacterial peritonitis, post-paracentesis circulatory dysfunction, acute kidney injury and hepatorenal syndrome are fully validated, and a treatment option has opened up in decompensated cirrhosis and in acute-on-chronic liver disease.

BACKGROUND: Current guidelines do not differentiate in the utilization of vasoactive drugs in patients with cirrhosis and acute variceal bleeding (AVB) depending on liver disease severity. MATERIAL AND METHODS: In this retrospective study, clinical outcomes in 100 patients receiving octreotide plus endoscopic therapy (ET) and 216 patients with ET alone were compared in terms of failure to control bleeding, in-hospital mortality, and transfusion requirements stratifying the results according to liver disease severity by Child-Pugh (CP) score and MELD. RESULTS: In patients with CP-A or those with MELD < 10 octreotide was not associated with a better outcome compared to ET alone in terms of hospital mortality (CP-A: 0.0 vs. 0.0%; MELD < 10: 0.0 vs. 2.9%, p = 1.00), failure to control bleeding (CP-A: 8.7 vs. 3.7%, p = 0.58; MELD < 10: 5.3 vs. 4.3%, p = 1.00) and need for transfusion (CP-A: 39.1 vs. 61.1%, p = 0.09; MELD < 10: 63.2 vs. 62.9%, p = 1.00). Those with severe liver dysfunction in the octreotide group showed better outcomes compared to the non-octreotide group in terms of hospital mortality (CP-B/C: 3.9 vs. 13.0%, p = 0.04; MELD ≥ 10: 3.9 vs. 13.3%, p = 0.03) and need for transfusion (CP-B/C: 58.4 vs. 71.6%, p = 0.05; MELD ≥ 10: 50.6 vs. 72.7%, p < 0.01). In multivariate analysis, octreotide was independently associated with in-hospital mortality (p = 0.028) and need for transfusion (p = 0.008) only in patients with severe liver dysfunction (CP-B/C or MELD ≥ 10). CONCLUSION: Patients with cirrhosis and AVB categorized as CP-A or MELD < 10 had similar clinical outcomes during hospitalization whether or not they received octreotide.

Background & Aims. It is unclear whether portal vein thrombosis (PVT) unrelated to malignancy is associated with reduced survival or it is an epiphenomenon of advanced cirrhosis. The objective of this study was to assess clinical outcome in cirrhotic patients with PVT not associated with malignancy and determine its prevalence. MATERIAL AND METHODS: Retrospective search in one center from June 2011 to December 2014. RESULTS: 169 patients, 55 women and 114 men, median age 54 (19-90) years. Thirteen had PVT (7.6%). None of the patients received anticoagulant treatment. The PVT group was younger (49 [25-62] vs. 55 [19-90] years p = 0.025). Child A patients were more frequent in PVT and Child C in Non-PVT. Median Model for End Stage Liver Disease (MELD) score was lower in PVT (12 [8-21] vs. 19 [7-51] p ≤ 0.001) p ≤ 0.001). There was no difference between upper gastrointestinal bleeding and spontaneous bacterial peritonitis in the groups. Encephalopathy grade 3-4 (4 [30.8%] vs. 73 [46.8%] p = 0,007) and large volume ascites (5 [38.5%] vs. 89 [57.1%] p= 0,012) was more common in non-PVT. Survival was better for PVT (16.5 ± 27.9 vs. 4.13 ± 12.2 months p = 0.005). CONCLUSIONS: We found that PVT itself does not lead to a worse prognosis. The most reliable predictor for clinical outcome remains the MELD score. The presence of PVT could be just an epiphenomenon and not a marker of advanced cirrhosis.

Cutaneous amyloidosis is a rare disease characterized by the deposition of amyloid in the dermis. It can be primary or secondary, depending on associated diseases. It has been linked to various autoimmune diseases, including primary biliary cirrhosis. We present the case of a patient with an autoimmune hepatitis-primary biliary cirrhosis overlap syndrome with concomitant cutaneous amyloidosis, a very unusual association, and discuss similar cases and possible pathophysiological implications.

Background: Nonalcoholic fatty liver disease (NAFLD) is a serious worldwide health problem, with an estimated global prevalence of 24%; it has a notable relationship with other metabolic disorders, like obesity and type 2 diabetes mellitus (T2DM). Nonalcoholic steatohepatitis (NASH) is one of the most important clinical entities of NAFLD, which is associated with an increased risk of progression to liver cirrhosis and hepatocellular carcinoma (HCC). Mexico is one of the countries with the highest prevalence of metabolic diseases; therefore, we sought to investigate the impact that these clinical entities have in the progression to advanced fibrosis in Mexican patients with NASH. Methods: We performed a multicenter retrospective cross-sectional study, from January 2012 to December 2017. A total of 215 patients with biopsy-proven NASH and fibrosis were enrolled. NASH was diagnosed according NAS score and liver fibrosis was staged by the Kleiner scoring system. For comparing the risk of liver fibrosis progression, we divided our sample into two groups. Those patients with stage F0-F2 liver fibrosis were included in the group with non-significant liver fibrosis (n=178) and those individuals with F3-F4 fibrosis were included in the significant fibrosis group (n=37). We carried out a multivariate analysis to find risk factors associated with liver fibrosis progression. Results: From the 215 patients included, 37 had significant liver fibrosis (F3-4). After logistic regression analysis T2DM (p=0.044), systemic arterial hypertension (p=0.014), cholesterol (p=0.041) and triglycerides (p=0.015) were the main predictor of advanced liver fibrosis. Conclusions: In a Mexican population, dyslipidemia was the most important risk factor associated with advanced liver fibrosis and cirrhosis.

Toxoplasma gondii infects up to one-third of the world's population, making it the protozoan that most infects people worldwide. Among the forms of presentation of toxoplasmosis, hepatitis is probably the least frequent with only a few case reports in the world's medical literature. Despite the fact that the first diagnostic test is the serology using the ELISA technique because its sensitivity is close to 100% in our case, it was reported negative. The biopsy gave the definitive diagnosis, and we were able to start treatment immediately. Although the first line of treatment is sulfadiazine and pyrimethamine, our sulfate allergic patient received an alternative regimen of doxycycline, clindamycin, and azithromycin with a good response. This is the only case of Toxoplasma hepatitis reported in Mexico and the only one in the world with negative serology with a good response to second-line treatment.
RESUMO
AIM: To investigate the main current etiologies of cirrhosis in Mexico. METHODS: We performed a cross-sectional retrospective multicenter study that included eight hospitals in different areas of Mexico. These hospitals provide health care to people of diverse social classes. The inclusion criteria were a histological, clinical, biochemical, endoscopic, or imaging diagnosis of liver cirrhosis. Data were obtained during a 5-year period (January 2012-December 2017). RESULTS: A total of 1210 patients were included. The mean age was 62.5 years (SD = 12.1), and the percentages of men and women were similar (52.0% vs 48.0%). The most frequent causes of liver cirrhosis were hepatitis C virus (HCV) (36.2%), alcoholic liver disease (ALD) (31.2%), and nonalcoholic steatohepatitis (23.2%), and the least frequent were hepatitis B virus (1.1%), autoimmune disorders (7.3%), and other conditions (1.0%). CONCLUSION: HCV and ALD are the most frequent causes of cirrhosis in Mexico. However, we note that non-alcoholic fatty liver disease (NAFLD) as an etiology of cirrhosis increased by 100% compared with the rate noted previously. We conclude that NAFLD will soon become one of the most frequent etiologies of liver cirrhosis in Mexico.
RESUMO
There are many autoimmune diseases associated with primary biliary cholangitis (PBC), known as primary biliary cirrhosis; however, the association between PBC and warm autoimmune hemolytic anemia (wAIHA) has rarely been reported. It is documented that hemolysis is present in over 50% of the patients with chronic liver disease, regardless of the etiologies. Due to the clear and frequent relationship between PBC and many autoimmune diseases, it is reasonable to suppose that wAIHA may be another autoimmune disorder seen in association with PBC. Here we reported a 53-year-old female patient diagnosed with wAIHA associated with PBC.

Treatment with polyethylene glycol-modified interferon alfa-2a (peginterferon) alone produces significantly higher sustained antiviral responses than treatment with interferon alfa-2a alone in patients with chronic hepatitis C virus (HCV) infection. We compared the efficacy and safety of peginterferon alfa-2a plus ribavirin, interferon alfa-2b plus ribavirin, and peginterferon alfa-2a alone in the initial treatment of chronic hepatitis C. Thirty-two patients were randomly assigned to treatment, and received at least one dose of medication consisting of 180 microg of peginterferon alfa-2a once weekly plus daily ribavirin (1,000 or 1,200 mg, depending on body weight) (n = 14), weekly peginterferon alfa-2a plus daily placebo (n = 6), or three million units of interferon alfa-2b thrice weekly plus daily ribavirin for 48 weeks (n = 12). More patients who received peginterferon alfa-2a plus ribavirin had a sustained virologic response (defined as the absence of detectable HCV RNA 24 weeks after cessation of therapy) than patients who received interferon alfa-2b plus ribavirin (7/14 vs. 4/12) or peginterferon alfa-2a plus placebo (0/6). The overall safety profiles of the three treatment regimens were similar. In conclusion, for patients with chronic hepatitis C, once-weekly peginterferon alfa-2a plus ribavirin was tolerated as well as interferon alfa-2b plus ribavirin and produced significant improvements in the rate of sustained viral reduction compared with interferon alfa-2b plus ribavirin or peginterferon alfa-2a alone.
