Non-targeted hepatitis C virus screening in acute care healthcare settings in the Southern Appalachian region.

Objectives: The objective of this study was to evaluate the performance of non-targeted hepatitis C virus (HCV) screening in emergency departments (EDs) and other healthcare settings in terms of patients identified with HCV infection and linked to HCV care. Methods: In the Southern Appalachian region of the United States, we developed non-targeted HCV screening and linkage-to-care programs in 10 institutions at different healthcare settings, including EDs, outpatient clinics, and inpatient units. Serum samples were tested for HCV antibodies, and if positive, reflexed to HCV ribonucleic acid (RNA) testing as a confirmatory test for active infection. Patients with positive RNA tests were contacted to link them to HCV care. Results: Between 2017 and 2019, among 195,152 patients screened for HCV infection, 16,529 (8.5%) were positive by antibody testing, 10,139 (5.2% of screened patients and 61.3% of patients positive by antibody test) were positive by RNA testing, and 5778 (3.0% of screened patients and 57.0% of patients positive by RNA test) were successfully linked to HCV care. Among 83,645 patients screened in EDs, 9060 (10.8%) were positive by HCV antibody, and 5243 (6.3%) were positive by RNA test. Among patients positive by RNA testing, linkage to care was lower for patients screened in the ED (44.1%) compared with outpatient clinics (67.6%) (P < 0.01) and inpatient units (50.9%) (P < 0.01). Conclusions: Non-targeted HCV screening in acute care settings can identify large numbers of people with HCV infection. To optimize the utility of these screening programs, future work is needed to develop best practices that consistently link these patients to HCV care.

Outcomes of Young Patients With Alcoholic Cirrhosis After First Hospitalization for Cirrhosis: A Carilion Clinic Experience.

Background  Alcoholic cirrhosis though uncommon in young patients is being reported more frequently and related mortality is also increasing.  Study aim  To evaluate risk factors associated with mortality among young patients (<40 years) with alcoholic cirrhosis and older patients (> 40 years old) after their first hospitalization in a tertiary referral academic center.  Methods Carilion clinic's electronic medical record (EPIC) was queried to identify all alcoholic patients hospitalized for the first time with either a new diagnosis of alcoholic cirrhosis or a prior diagnosis of this from 2008 to 2016 with follow-up through June 2018. Information on demographics, comorbidities, lab values, procedures, and mortality was extracted. The cumulative risks of long-term mortality after the first hospitalization were estimated using Kaplan-Meier curves and compared between the two groups; those < 40 years of age and those > 40 years of age. Demographic data, lab values, and comorbidities associated with cirrhosis were assessed using multivariable Cox proportional hazard analysis to determine risk factors associated with long-term mortality.  Results We identified 65 young patients out of a total of 325 patients admitted for the first time for alcoholic cirrhosis (mean age: 34.6 ± 4.7 yrs, 72.3% males, 74.4% current alcohol users, 52.3% current smokers, 12.6% current illicit drugs users). The one, three, and five-year cumulative mortality after the first hospitalization was 21.1 %, 31.1%, and 49.7% respectively. The median survival for young patients was longer as compared to the older patients (p<0.001); likely related to high early mortality in older patients who had many other comorbidities. On multivariate Cox proportional hazard analysis, increased age [hazard ratio (HR) 1.03; 95% confidence interval (CI), 1.01-1.05], neutrophils-to-lymphocytes ratio (NLR) at first hospital discharge (HR 1.02; 95% CI, 1.01-1.04), the presence of encephalopathy (HR, 1.93; 95% CI, 1.06-3.55), and initial MELD (model for end-stage liver disease) score (HR, 1.13; 95% CI, 1.08-1.19) were associated with increased risk of mortality. Though the majority of patients endorsed current alcohol and tobacco use before the admission, it was not significantly associated with mortality.  Conclusions  Five-year cumulative mortality for patients < 40 years of age with alcoholic cirrhosis after their first hospitalization is 49.7%. Old age, most recent NLR, hepatic encephalopathy, and MELD score on admission were associated with increased late mortality.

Fecal Lactoferrin and Other Stool Markers during Normal Pregnancy and in Inflammatory Bowel Diseases: A Prospective Study and Review of the Literature.

INTRODUCTION: Management of inflammatory bowel diseases (IBDs) - both Crohn's disease (CD) and ulcerative colitis (UC) - during pregnancy can be challenging since most monitoring tools available in nonpregnant patients are contraindicated. OBJECTIVES: The aim of the study was to test whether fecal inflammatory markers - specifically fecal lactoferrin - physiologically change during normal pregnancy as a prerequisite to use them to monitor IBD activity during pregnancy. METHODS: Fecal lactoferrin was tested in healthy pregnant and nonpregnant women from the same geographic area and age range (18-40 years) - all negative for clinical gastrointestinal tract inflammation. A retrospective review of fecal lactoferrin levels contrasted with the Simple Endoscopic Score for CD, and the Disease Activity Index for UC was also performed in women with active IBDs within the same age range and geographical area. RESULTS: In 30 nonpregnant subjects, fecal lactoferrin levels were 0.87 ± 1.08 µg/g. In 49 pregnant subjects, levels were 0.59 ± 0.83, 0.87 ± 1.13, and 0.85 ± 1.06 µg/g during the first, second, and third trimester, respectively (p = 0.64), with average levels for the 3 trimesters of 0.81 ± 1.04 µg/g (p = 0.61 compared to nonpregnant subjects). Sequential fecal lactoferrin levels (n = 26) did not differ from one trimester to the other in the individual subjects (p = 0.80). In 45 female IBD patients (27 with CD and 18 with UC), fecal lactoferrin levels were correlated with disease activity as defined by the endoscopic scores: 218, 688, and 1,175 µg/g for CD and 931, 2,088, and 2,509 µg/g for UC, respectively, for mild, moderate, and severe activity. CONCLUSIONS: Fecal lactoferrin levels during normal pregnancy are superimposable to those of nonpregnant women and significantly below levels in women of the same childbearing age with active IBDs. Additional published data - reviewed in this atricle - and our own indicate that fecal lactoferrin and other markers can be potentially used to monitor disease activity in pregnant IBD patients.

Fecal lactoferrin accurately reflects mucosal inflammation in inflammatory bowel disease.

BACKGROUND: Studies have demonstrated a potential role for fecal biomarkers such as fecal calprotectin (FC) and fecal lactoferrin (FL) in monitoring inflammatory bowel diseases (IBD) - Crohn's disease (CD) and ulcerative colitis (UC). However, their correlation to endoscopic scores, disease severity and affected intestinal surface has not been extensively investigated. AIM: To correlate FL, and for comparison white blood cell (WBC) and C-reactive protein (CRP), with endoscopic scores, disease extent and location in CD and UC. METHODS: Retrospective analysis in 188 patients who had FL, CRP and WBC determined within 30 d of endoscopy. Disease location, disease extent (number of intestinal segments involved), disease severity (determined by endoscopic scores), timing of FL testing in relation to colonoscopy, as well as the use of effective fast acting medications (steroids and biologics) between colonoscopy and FL measurement, were recorded. RESULTS: In 131 CD and 57 UC patients, both CRP and FL - but not WBC - distinguished disease severity (inactive, mild, moderate, severe). In patients receiving fast-acting (steroids or biologics) treatment in between FL and colonoscopy, FL showed a higher correlation to endoscopic scores when tested before vs after the procedure (r = 0.596, P < 0.001, vs r = 0.285, P = 0.15 for the Simple Endoscopic Score for CD; and r = 0.402, P = 0.01 vs r = 0.054 P = 0.84 for Disease Activity Index). Finally, FL was significantly correlated with the diseased mucosal surface (colon-ileocolon > small bowel) and the number of inflamed colon segments. CONCLUSION: FL and CRP separated disease severity categories with FL showing lower discriminating P-values. FL showed a close correlation with the involved mucosal surface and with disease extent and was more closely correlated to endoscopy when determined before the procedure - this indicating that inflammatory activity changes associated with therapy might be rapidly reflected by FL levels. FL can accurately and timely characterize intestinal inflammation in IBD.
