Antibiotic Prophylaxis for Upper Gastrointestinal Bleed in Liver Cirrhosis; Less May Be More.

INTRODUCTION: Administration of antibiotics in patients with cirrhosis and upper gastrointestinal bleeding has been shown to improve outcomes. Little is known regarding optimum duration of prophylactic antibiotics. Seven days of antibiotics are generally recommended but very few studies have compared antibiotic duration to clinical outcomes in current available scientific literature. The goal of our study was to study the effect of shorter antibiotic duration on patient outcomes. METHODS: We conducted a retrospective cohort study of patients with cirrhosis presenting with upper GI bleeding at our institute from 2010 to 2018. Patients were divided into three cohorts based on duration of antibiotic administration for prophylaxis: 1-3 days of antibiotics, 4-6 days of antibiotics and 7 days or more of antibiotics. Rates of infection diagnosis within 30 days, rebleeding, and mortality were compared between the three groups with Chi square, Fisher Exact and Kruskall-Wallace tests. Multivariable analysis was conducted to evaluate independent risk factors for infection. RESULTS: Medical charts of 980 patients with cirrhosis and upper GI bleeding during the study period were reviewed. A total of 303 with upper gastrointestinal bleeding were included in the final sample, of these 243 patients received antibiotics for prophylaxis and were included for analysis. Seventy-seven patients received antibiotic therapy for 3 days or less, 69 patients for 4-6 days, and 97 patients longer than 6 days. The three groups were well matched in demographic and clinical variables. Twenty-seven patients developed infections within 30 days of bleeding. MELD-Na score at presentation and presence of ascites were associated with infection within 30 days. Rates of infection were not statistically different between the three antibiotic groups (p = 0.78). In the thirty days following the GI bleed, pneumonia was the most diagnosed infection (eleven patients) followed by urinary tract infections (eight patients). Four patients developed spontaneous bacterial peritonitis and three were diagnosed with bacteremia. There was no difference in time to infection (Kruskall Wallace test p = 0.75), early re-bleeding (p = 0.81), late re-bleeding (p = 0.37) and in-hospital mortality (p = 0.94) in the three groups. Six patients in the cohort developed C. Difficile infection; no patient in the short antibiotic group developed C. Difficile infection. CONCLUSION: Short course of antibiotics for prophylaxis (3 days) appears safe and adequate for prophylaxis in patients with cirrhosis with upper gastrointestinal bleeding if there is no active infection.

Outcomes of SARS-CoV-2 infection in patients with celiac disease: a multicenter research network study.

Background: Celiac disease (CD) is associated with an increased risk for respiratory infections and severe outcomes. No data have been reported in the scientific literature regarding the outcomes of COVID-19 in this population. The aim of this study was to report matched clinical outcomes in a large cohort of 930 patients with COVID-19 in the setting of known CD. Methods: Analysis of a multicenter research network TriNETX was performed, including COVID-19 patients aged more than 16 years. Outcomes of COVID-19-positive patients with concurrent CD were compared with a propensity-matched cohort of patients without CD. Results: A total of 341,499 patients with SARS-CoV-2 infection were identified on the research network: 930 (0.27%) with CD and 340,569 (99.73%) without CD. In the 30- and 60-day periods post SARS-CoV-2 infection, 12 (1.29%) and 13 (1.40%) deaths, respectively, were reported in the CD group. Fewer patients in the CD group reached the composite outcome of either mechanical ventilation or mortality at 60 days (risk ratio 0.58, 95% confidence interval 0.36-0.95). After propensity matching, no difference in clinical outcomes was observed. Conclusion: Our data suggest that patients with CD are not at increased risk of COVID-19-related morbidity or mortality.

Addressing rural health disparity with a novel hospital sleep apnea screening: Precision of a high-resolution pulse oximeter in screening for sleep-disordered breathing.

PURPOSE: High-resolution pulse oximetry (HRPO) may offer a low-cost and simple screening option for sleep-disordered breathing (SDB) that could be vitally important in rural areas with limited healthcare resources and specialty care. Our team hypothesized that application of this technology to a broad cohort of rural dwelling hospitalized individuals would demonstrate congruence similar to previous urban studies comparing HRPO to portable sleep monitors. METHODS: This retrospective study was conducted at West Virginia University Hospital and compared indices obtained from HRPO with those obtained from a type III portable sleep monitor (PM) on the same night. RESULTS: A total of 365 individuals underwent evaluation. The mean oxygen desaturation index (18.8 ± 19.3 events/h) from the HRPO was slightly higher than the mean respiratory event index (16.0 ± 18.1 events/h, p ≤ 0.001) from the PM. ROC curves were developed for thresholds of apnea severity predicted by the screening program. The AUC values for all three thresholds exceeded 0.92 and for a respiratory event index (REI) of ≥ 30 was 0.965. Indices from the PM and HRPO demonstrated agreement in those individuals with screening suggestive of moderate to severe disease. CONCLUSION: This study demonstrates that use of HRPO in screening for SDB in hospitalized patients from rural communities is as accurate as PM and may serve as a simple cost-effective tool to address sleep health disparities in these regions with significant health inequity. Our data extend previous findings by applying HRPO to a larger hospitalized cohort with highly prevalent cardiopulmonary disease.

Warfarin Use Is Associated with Increased Mortality at One Year in Patients with Idiopathic Pulmonary Fibrosis.

OBJECTIVES: We studied the safety and efficacy of warfarin compared to direct acting oral anticoagulant use in patients with IPF. METHODS: We conducted a retrospective cohort study of all patients with IPF who were prescribed warfarin or direct acting oral anticoagulants (DOACs) for cardiac or thromboembolic indications and followed at our institute for their care. Univariate tests and multivariable logistic regression analyses were used for assessing association of variables with outcomes. RESULTS: A total of 73 patients were included in the study with 28 and 45 patients in the warfarin and DOAC groups, respectively. Univariable analysis revealed a significant difference in mortality in one year between warfarin and DOAC groups (7/28 vs. 3/45, p value 0.027). Significantly more patients in the warfarin group suffered an exacerbation that required hospitalization within one year (9/28 vs. 5/45, p value 0.026). Multivariate logistic regression analysis showed that anticoagulation with warfarin was independently associated with mortality at one-year follow-up (OR: 77.4, 95% CI: 5.94-409.3, p value: 0.007). CONCLUSION: In our study of patients with IPF requiring anticoagulants, we noted statistically significant higher mortality with warfarin anticoagulation when compared to DOAC use. Further larger prospective studies are needed to confirm these findings.

Patients with idiopathic pulmonary fibrosis have poor clinical outcomes with COVID-19 disease: a propensity matched multicentre research network analysis.

INTRODUCTION: Outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with pre-existing idiopathic pulmonary fibrosis (IPF) remain understudied, and it is unknown if IPF is an independent predictor of worse disease course. Herein, we report the clinical outcomes in a large cohort of 251 patients with COVID-19 in the setting of known IPF. Outcomes were compared with a propensity matched cohort of patients with COVID-19 without IPF. METHODS: Analysis of a federated multicentre research network TriNetX was performed including patients more than 16 years of age diagnosed with SARS-CoV-2 infection. Outcomes in patients diagnosed as positive for SARS-CoV-2 infection with concurrent IPF were compared with a propensity matched cohort of patients without IPF. RESULTS: A total of 311 060 patients with SARS-CoV-2 infection on the research network were identified, 251 patients (0.08%) carried a diagnosis of IPF. Mean age of patients with IPF was 68.30±12.20 years, with male predominance (n=143, 56.97%). Comorbidities including chronic lower respiratory diseases, diabetes mellitus, ischaemic heart disease and chronic kidney disease were more common in patients with IPF when compared with the non-IPF cohort. After propensity matching, higher rates of composite primary outcome (death or mechanical ventilation) at 30 and 60 days, as well as need for hospitalisation, critical care, and acute kidney injury were observed in the IPF cohort. CONCLUSION: Poor outcomes of COVID-19 disease were observed in patients with IPF after robust matching of confounders. Our data confirm that patients with IPF constitute a high-risk cohort for poor outcomes related to COVID-19 disease.

Reduced risk of post ERCP pancreatitis in statin users.

BACKGROUND: One of the most feared complications of endoscopic retrograde cholangiopancreatography (ERCP), with an incidence of 3.5 to 15%, is post ERCP pancreatitis (PEP). Given the role of statins in the reduction of systemic and pancreatic intraluminal inflammation, we hypothesized that the use of statins may lower the risk of PEP. METHODS: A retrospective cohort study of all patients undergoing ERCP at West Virginia University during the years 2016 and 2017 was performed. Possible association of collected variables with PEP was assessed with Univariate tests and multivariable logistic regression analyses. RESULTS: A total of 1162 ERCPs were included. Mean age was 60.12 years (SD: 17.5). 51.3% of the participants were female. Two hundred and sixty-three participants underwent more than one ERCP during the study period. Seven hundred and ninety-nine ERCPs (78.8%) were conducted in participants who were not taking a statin medication at the time of ERCP, while 363 participants were on statin medications at the time of ERCP; 118 and 245 participants were taking high dose statins (atorvastatin 40-80 mg or rosuvastatin 20 mg), and low/medium dose statins (all other statin regimens) at the time of the procedure, respectively. The overall incidence of PEP in the cohort was 7.3%. In the non-statin and statin groups, 9.5 and 3.4% of participants developed PEP, respectively. On univariate analysis, young age, no statin use, history of PEP, and endoscopic sphincterotomy were found to be significantly associated with the development of PEP. In a binary logistic regression model, young age (P = 0.033), history of PEP (P = 0.0001, OR 2.41, 95% CI: 1.05-5.51) and endoscopic sphincterotomy (P = 0.038, OR 2.85, 95% CI: 1.7-4.78) were found to be associated with increased risk of PEP. Statin usage was found to be protective against PEP, (OR 0.35, 95% CI: 0.18-0.69). CONCLUSION: Chronic statin usage is protective against post ERCP pancreatitis, and our findings suggest a potential role of these drugs as prophylactic agents. Randomized controlled trials are needed to establish any potential clinical application.

Systemic Lupus Erythematosus Presenting with Ischemic Proctitis and Abdominal Compartment Syndrome.

Ischemic colitis and proctitis is a rare manifestation of systemic lupus erythematosus (SLE) and results from mesenteric vasculitis. Owing to diverse blood supply and presence of multiple collaterals, rectum is the least effected site in SLE enteritis. Ischemic proctocolitis as the presenting feature of SLE is exceedingly rare, with only three cases reported in the published scientific literature. We present the first case of SLE presenting as ischemic proctitis, leading to intraperitoneal hemorrhage and abdominal compartment syndrome. A young lady presented with ischemic proctitis and a hematoma masquerading as a pelvic mass, with subsequent development of massive intraperitoneal hemorrhage, shock, and rectal perforation. The patient required urgent surgery and was initiated on high-dose steroids.

Independent association of obstructive sleep apnea with Barrett's esophagus.

BACKGROUND AND AIM: Current guidelines suggest screening at-risk groups of patients for Barrett's esophagus (BE), a precursor to esophageal cancer. Although BE and obstructive sleep apnea (OSA) have common risk factors, including elevated body mass index and gastroesophageal reflux disease (GERD), the relationship between these two conditions has not been well established. METHODS: Retrospectively, all patients who had undergone a polysomnography and esophagogastroduodenoscopy at West Virginia University Hospital from 2013 to 2018 were identified and divided into groups on the basis of the presence or absence of OSA. Clinical course and procedure reports were reviewed to identify relevant variables. RESULTS: One thousand ninety-one patients met inclusion criteria; 60.9% were female, and mean age of participants was 53.5 years. Univariate analysis revealed that male gender, age, diagnosis of OSA, severity of OSA, and a clinical diagnosis of GERD were associated with BE (P values < 0.05). Multiple logistic regression incorporating age, sex, clinical diagnosis of GERD, smoking history, body mass index, Helicobacter pylori status, and presence of hiatal hernia was utilized. Patients with OSA had an increased risk of BE than had those without OSA (P < 0.001, odds ratio 3.26 [1.72-6.85]). The risk increased with increasing severity of OSA, categorized in apnea-hypopnea index increments of 10. CONCLUSION: Obstructive sleep apnea is associated with BE, a relationship that is independent of other known risk factors. Additionally, this risk increases with increasing severity of OSA. Future efforts should determine if patients with severe OSA need to be screened for BE due to its potential for causing esophageal cancer.
