Comparative Study
New consensus definition of acute kidney injury accurately predicts 30-day mortality in patients with cirrhosis and infection.
Participants at a consensus conference proposed defining cirrhosis-associated acute kidney injury (AKI) based on a >50% increase in serum creatinine level from the stable baseline value in <6 months or an increase of ≥ 0.3 mg/dL in <48 hours. We performed a prospective study to evaluate the ability of these criteria to predict mortality within 30 days of hospitalization among patients with cirrhosis and infection. ⋯ Among patients with cirrhosis, 30-day mortality is 10-fold higher among those with irreversible AKI than those without AKI. The consensus definition of AKI accurately predicts 30-day mortality, length of hospital stay, and organ failure.

Randomized Controlled Trial
Validation of endoscopic activity scores in patients with Crohn's disease based on a post hoc analysis of data from SONIC.
Mucosal healing might alter midterm and long-term outcomes of patients with Crohn's disease (CD) and has become an important end point in clinical trials. However, the minimal degree of mucosal improvement (endoscopic response) required to alter midterm outcomes is not known. We aimed to determine the best definition of endoscopic response by evaluating data on the Simple Endoscopic Score for Crohn's Disease (SES-CD) and the Crohn's Disease Endoscopic Index of Severity (CDEIS) from the Study of Biologic and Immunomodulator Naive Patients in Crohn's Disease (SONIC trial). ⋯ In patients with CD, mucosal healing and endoscopic response (defined as a decrease from baseline in SES-CD or CDEIS of at least 50%) at week 26 of treatment identified those most likely to be in CFREM at week 50. The ability of the proposed endoscopic response cutoff value to predict midterm CFREM should be validated in an independent, prospective cohort. Its correlation with changes in long-term disease progression still needs to be demonstration. ClinicalTrials.gov, Number: NCT00094458.

Randomized Controlled Trial Multicenter Study
Effects of ribavirin dose reduction vs erythropoietin for boceprevir-related anemia in patients with chronic hepatitis C virus genotype 1 infection--a randomized trial.
Treatment of hepatitis C virus (HCV) infection with boceprevir, peginterferon, and ribavirin can lead to anemia, which has been managed by reducing ribavirin dose and/or erythropoietin therapy. We assessed the effects of these anemia management strategies on rates of sustained virologic response (SVR) and safety. ⋯ Reduction of ribavirin dosage can be the primary approach for management of anemia in patients receiving peginterferon, ribavirin, and boceprevir for HCV infection. Reduction in ribavirin dosage throughout the course of triple therapy does not affect rates of SVR. However, it is important that the patient receives at least 50% of the total amount (milligrams) of ribavirin assigned by response-guided therapy. ClinicalTrials.gov number, NCT01023035.
