Spontaneous bacterial peritonitis is the most frequent bacterial infection in patients with cirrhosis. The reported incidence varies between 7% and 30% in hospitalized patients with cirrhosis and ascites, representing one of their main complications. Outcomes in patients with spontaneous bacterial peritonitis are poor since acute kidney injury, acute-on-chronic liver failure, and death occur in as much as 54%, 60%, and 40% of the patients, respectively, at midterm. Early antibiotic treatment of spontaneous bacterial peritonitis is crucial. However, the landscape of microbiological resistance is continuously changing, with an increasing spread of multidrug-resistant organisms that make its current management more challenging. Thus, the selection of the empirical antibiotic treatment should be guided by the severity and location where the infection was acquired, the risk factors for multidrug-resistant organisms, and the available information on the local expected bacteriology. The use of albumin as a complementary therapy for selected high-risk patients with spontaneous bacterial peritonitis is recommended in addition to antibiotics. Even though antibiotic prophylaxis has proven to be effective to prevent spontaneous bacterial peritonitis, a careful selection of high-risk candidates is crucial to avoid antibiotic overuse. In this article we review the pathogenesis, risk factors, and prognosis of spontaneous bacterial peritonitis, as well as the current evidence regarding its treatment and prophylaxis.
The AFP model could be useful in Latin-American countries to better select patients for LT in subgroups presenting with extended criteria. However, particular attention should be focused on patients with HBV.
Registration studies show entecavir (ETV) to be effective and safe in NUC-naïve patients with chronic hepatitis B, but relapse rates after treatment discontinuation have not been well established. Relapse rates and predictors of relapse were evaluated in naïve HBeAg-positive and HBeAg-negative patients treated with ETV. Treatment duration was defined according to international guidelines. Virological relapse was defined as reappearance in serum of hepatitis B virus (HBV) DNA to >2000 IU/mL after discontinuation of treatment. A hundred and sixty-nine consecutive patients were treated for a median 181 weeks. 61% were HBeAg positive, 23% had cirrhosis, and mean HBV DNA level was 6.88 ± 1.74 log10 IU/mL. Ninety-two per cent became HBV DNA negative; 71% of HBeAg+ve patients became HBeAg negative and 68% anti-HBe positive; 14% became HBsAg negative and 13% anti-HBs positive. At the end of the study, 36 patients discontinued treatment: one due to breakthrough associated with resistant variants and 35 (20%) due to sustained virological response; 33 of these patients developed HBeAg seroconversion and 18 HBsAg seroconversion. Median off-treatment time was 69 weeks. Nine patients (26%), all HBeAg positive at baseline, developed virological relapse after a median 48 weeks off-treatment, 3 of them showed HBeAg reversion and 4 lost anti-HBe. No patient with HBsAg seroconversion relapsed. HBeAg clearance after week 48 of treatment was associated with an increase risk of relapse. After ETV discontinuation, HBsAg seroconversion was maintained in 100% of the patients, HBeAg seroconversion maintained in 90%, and virological relapse rate was 24%.
AIMTo investigate any changing trends in the etiologies of hepatocellular carcinoma (HCC) in Argentina during the last years.METHODSA longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease (NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.RESULTSA total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers (n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC (37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLD-HCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015 (4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3% (P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups (6.6 ng/mL vs 26 ng/mL; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.CONCLUSIONThe growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
