6%) were malnourished, 13,945 (4.4%) were obese, and 11,909 (3.8%) were morbidly obese. A total of 98,404 patients (31.1%) had at least one infection during hospitalization. Infection was most prevalent among malnourished patients (49.4%), followed by morbidly obese (40.9%), and then obese patients (32.2%). In multivariable analysis, malnutrition and morbid obesity predicted infection (Table 1). Among infected patients, risk factors for mortality included malnutrition (OR=2.10; 95% CI 2.022.20) and morbid obesity (OR=1.47;

95% CI 1.41-1.54). Regarding specific infections, malnourished patients had greatest prevalence of sepsis, UTI, LRI, SBP and CDI, while morbidly obese patients had highest prevalence of cellulitis. Prevalence of bacteremia was similar among all patient groups.

Conclusion: Malnutrition and morbid obesity are associated with infection acquisition in cirrhosis Ku-0059436 research buy and higher mortality among infected cirrhotics. The prevalence of specific infections also varies depending on nutritional status. Further study is Protein Tyrosine Kinase inhibitor needed regarding the impact and optimization of nutritional status in chronic liver disease. Disclosures: Tram T.

Nguyen, Amit Rajaram, Phillip Zakowski Aim: To determine what clinical factors contribute to the high mortality from septic shock among cirrhotics with spontaneous bacterial peritonitis (SBP). Methods: From the CATTS Database between 1996 and 2011, retrospective cohort study of all cirrhotic patients with septic shock and evidence of SBP (neu-trophils > 250 or positive tap). Results: Among 126 cirrhotics (mean age 55, 60% male),

in-hospital mortality was 82%. In comparing survivors (n=23) with non-survivors (n=103), this website survivors had lower mean admission APACHE II (22 vs. 32), MELD (24 vs.34) and serum lactate (4.9 vs. 8.9, p<0.001 for all) and were less likely to have co-existent bloodstream infection (BSI) (22% vs. 50%, p=0.015). Survivors were more likely to receive appropriate initial antimicrobial therapy (100% vs. 75%, p=0.013) and receive therapy earlier (median 1.8 vs. 9.5 hours, p<0.001). Predicted death rates (regression) according to APACHE II score, lactate and time to antimicrobials are shown in Figure 1 . On multivariable analysis, APACHE II (Odds Ratio 1.45 (1.04-2.02, p=0.03), lactate (OR 2.34 (1.04-5.29), p=0.04) and time delay to appropriate antimicrobials (OR 1.86 per hour (1.10-3.14), p=0.02) were all significantly associated with increased mortality. Age, gender and presence of co-existent BSI did not impact outcome. This model performed well (c-statistic 0.98).
