Mifepristone is frequently used in large doses for management of Cushing’s syndrome. This is a case of a 35-year-old woman with Cushing’s syndrome, who presented with abdominal pain and jaundice. A month prior to admission, she had been started on a daily dose of 1,200 mg mifepristone. After evaluating for various other causes of liver injury, biopsy revealed cholestatic pattern of liver disease, likely associated with drug-induced hepatotoxicity. Mifepristone was discontinued and her symptoms resolved. We believe this is one of the first few reported cases of drug-induced liver injury (DILI) associated with mifepristone use.

Colectomy is the curative management for ulcerative colitis (UC). Multiple studies have reported racial disparities for colectomy before the advent of anti-TNF alpha agents. The aim of this study was to describe racial and geographic differences in colectomy rates among hospitalized patients with UC after anti-TNF therapy was introduced. We examined all patients discharged from the hospital between 2010 and 2014 with a primary diagnosis of UC or of complications of UC. The data were evaluated for race and colectomy rates among the hospitalized patients with UC. The unadjusted national colectomy rate among hospitalized patients with UC between 2010 and 2014 was 3.90 per 1000 hospitalization days (95% confidence interval, 3.72-4.08). The undajusted colectomy rates in African American (2.33 vs 4.35; P < 0.001) and Hispanic patients (3.99 vs 4.35; P ≤ 0.009) were considerably lower than those for White patients. After adjustment for confounders, the incidence rate ratio for African American as compared to White patients was 0.43 (95% confidence interval, 0.32-0.58; P < 0.001). Geographic region of the United States also showed significant variation in colectomy rates, with western regions having the highest rate (4.76 vs 3.20; P < 0.001). Racial and geographical disparities persist for the rate of colectomy among hospitalized patients with UC. The national database analysis reveals that colectomy rates for hospitalized African American and Hispanic patients were lower than those for White patients. Further studies are important to determine the social and biologic foundations of these disparities.

Background: Acute pancreatitis (AP) is a leading cause of gastrointestinal hospital admissions, with up to 40% mortality in patients with moderate–severe AP. Glycoprotein acetylation (GlycA) is measured as a nuclear magnetic resonance signal (NMR) of the post-translational modification of glycosylated acute-phase proteins released during inflammation. We aimed to investigate the role of GlycA as an inflammatory biomarker of AP. Methods: We prospectively enrolled 20 AP patients and 22 healthy controls and collected EDTA plasma samples at admission and discharge. NMR spectra were acquired from these samples using a 400 MHz Vantera^® Clinical Analyzer, and GlycA concentrations were calculated (normal = 400 μmol/L). The GlycA NMR signal, at 2.00 ± 0.01 ppm in the NMR spectrum, is derived from the N-acetyl methyl group protons within the carbohydrate side chains of circulating glycoproteins such as α1-acid glycoprotein, haptoglobin, α1-antitrypsin, α1-antichymotrypsin, and transferrin. GlycA levels were then compared between AP patients and controls, as well as within the AP group, based on etiology and severity. Results: Demographic comparisons were similar, except for a higher BMI in AP patients compared to healthy controls (29.9 vs. 24.8 kg/m²; p < 0.001). AP was mild in 10 patients, moderate in 7, and severe in 3. GlycA levels were higher in AP patients than healthy controls on admission (578 vs. 376 μmol/L, p < 0.001) and at discharge (655 vs. 376 μmol/L, p < 0.001). GlycA levels were significantly higher in patients with moderate–severe AP than in those with mild AP at discharge (533 vs. 757 μmol/L, p = 0.023) but not at admission. After adjusting for BMI, multivariable regression indicated that patients with GlycA levels > 400 μmol/L had significantly higher odds of having AP of any severity (OR = 6.88; 95% CI, 2.07–32.2; p = 0.004) and mild AP (OR = 6.12; 95% CI, 1.48–42.0; p = 0.025) than controls. Conclusion: Our pilot study highlights the use of GlycA as a novel diagnostic biomarker of inflammation in patients with AP. Our study shows that GlycA levels were significantly higher in hospitalized AP patients compared to healthy controls. Patients with moderate-to-severe AP had higher GlycA levels compared to patients with mild AP at the time of their hospital discharge, suggesting persistent inflammation in patients with severe disease.

Background Patients with ascites resulting from chronic debilitating diseases often require non-oral enteral nutrition and undergo placement of a percutaneous endoscopic gastrostomy (PEG) tube. The aim of our study was to assess the nationwide trends and outcomes of PEG tube placement among patients with ascites. Methods Using the Nationwide Inpatient Sample (NIS), we conducted a retrospective analysis of adult patients (>= 18 years) who underwent PEG tube placement (n=789,167) from 2010-2014. We divided these patients into 2 groups: with or without ascites. We compared demographics, complications, and in-hospital outcomes between the groups. STATA-13 was used for statistical analysis. Statistical significance was assigned at P<0.05. Results Patients with ascites who underwent PEG tube placement were found to have a significantly higher rate of complications, including peritonitis (7.52 vs. 0.72%; P<0.001), aspiration pneumonia (20.41 vs. 2.69%; P<0.001), hemoperitoneum (0.72 vs. 0.19%; P<0.001), procedure-related hemorrhage (1.69 vs. 0.9%; P<0.001) and esophageal perforation (0.51 vs. 0.47%; P<0.001). In addition, these patients also had higher in-hospital mortality (16.33% vs. 7.02%; P<0.001) despite having a relatively lower prevalence of comorbidities. Length of stay was longer in the ascites group (28.08 vs. 19.45 days; 0.001). Over the study period, however, we observed an increasing trend for PEG tube placement in hospitalized patients with ascites. Conclusion PEG tube placement in hospitalized patients with ascites is associated with significantly higher mortality, a longer stay, and more procedure-related complications.
