Correlation Between Serum and Fecal Biomarkers and Patient-Reported Outcomes in Patients with Crohn's Disease and Ulcerative Colitis.

BACKGROUND: Patient-reported outcomes (PROs), such as the short CD activity index (sCDAI) and partial Mayo Score (PMS), are used to define clinical remission in IBD, but may not represent the true degree of inflammation and endoscopy is invasive. Non-invasive testing options include c-reactive protein (CRP) and fecal calprotectin (FCP). AIM: The aim of this study was to assess the degree of correlation of non-invasive biomarkers with PROs and the impact other clinical variables can have on their levels. METHODS: We reviewed data collected from the prospective cohort, Study of a Prospective Adult Research Cohort with IBD (SPARC-IBD), comprised of over 3000 patients from 17 tertiary referral centers. Demographic and clinical variables were analyzed by disease type, disease severity was based on PROs, and baseline CRP and FCP were measured. For comparative analysis, we performed Fisher's exact test and Welch's t test, where p < 0.05 was significant. RESULTS: 1547 patients were included; 63% had CD, 56% were female, with an average disease duration of 13.6 years. CRP and FCP were associated with symptom severity in inflammatory CD. CRP was useful to differentiate symptoms across different disease locations in CD, whereas FCP was associated with symptom severity in Crohn's colitis only. For UC, FCP was able to distinguish symptom severity better in distal UC, whereas in extensive or pancolitis, it was useful only to distinguish severe symptoms from other categories of symptom severity. CONCLUSION: PROs correlate with CRP and FCP; however, disease location and phenotype impact their ability to distinguish symptom severity.

Factors Associated With Extraintestinal Manifestations of Inflammatory Bowel Disease in SPARC-IBD.

BACKGROUND: Extraintestinal manifestations (EIMs) of inflammatory bowel diseases (IBDs) are a common and debilitating feature of disease, occurring in up to 40% of patients with IBD, yet predicting who may develop them is difficult. The goal of our study was to better characterize which patients may be at highest risk of developing not only 1 EIM, but also multiple EIMs, across both diseases. METHODS: A retrospective study of participants enrolled in the SPARC IBD (Study of Prospective Adult Research Cohort with IBD) registry was performed, and demographic and clinical data were analyzed. A total of 1211 patients with data available on EIMs were included, and differences among variables with vs without EIMs were assessed. RESULTS: A total of 329 participants with at least 1 EIM were identified, compared with 882 participants without any EIMs. Crohn's disease patients and women were more likely to have 2 or more EIMs (P = .005 and P ≤ .001, respectively). Participants with ocular manifestations were likeliest to have at least 2 EIMs (P ≤ .001). Even when diagnosis was controlled for, involvement of the right colon (P = .021) was predictive of IBD-associated arthritis across both diseases in a multivariate generalized linear model. CONCLUSIONS: This is the first comprehensive large-cohort assessment of how EIMs relate to one another at the individual vs systems levels. Further, our analysis is the first to recognize specific locations of colon involvement associated with EIMs of IBD, regardless of IBD type. These results are important in identifying patients at risk of developing future EIMs and may help with risk stratification when choosing treatments.

Although extraintestinal manifestations frequently complicate inflammatory bowel disease, predicting those at highest risk of developing them is difficult. We found female patients with Crohn's disease, ocular, and dermatologic manifestations are likeliest to develop multiple extraintestinal manifestations. Further, we found right-sided involvement is predictive of inflammatory bowel disease­associated arthritis.

Histologic Inflammation can Predict Future Clinical Relapse in Ulcerative Colitis Patients in Endoscopic Remission.

Background: In ulcerative colitis (UC), endoscopic improvement, defined as a Mayo Endoscopic Score (MES) of 0 or 1, is a target of treatment. The aim of our study was to evaluate the risk of clinical relapse between patients with an MES of 0 or 1 and determine if histologic activity using the Robarts Histopathologic Index (RHI) was predictive of clinical relapse. Methods: UC patients with an MES score of 0 or 1, no prior colectomy, and at least 1 year of outpatient follow-up after colonoscopy were included. Demographic, clinical characteristics, and clinical relapse were retrospectively collected. Biopsy specimens were read by a gastrointestinal pathologist. Primary outcome was defined as a composite of relapse requiring change in medical therapy, new steroid use, UC-related hospitalization, and/or colectomy. Results: Four hundred and forty-five UC patients were identified. Ninety-five percent of patients with MES 0 were in histologic remission by the RHI whereas only 35% of patients with MES 1 were in histologic remission. Twenty-six percent of patients experienced a clinical relapse; patients with MES 1 or RHI > 3 were significantly more likely to relapse (P < .01) compared to patients with MES 0 or RHI ≤ 3. When patients were stratified into 4 groups (MES 0, RHI ≤ 3; MES 0, RHI > 3; MES 1, RHI ≤ 3; MES 1, RHI > 3) and adjusted for age and sex, RHI > 3 was predictive of relapse (P = .008). Conclusions: UC patients with endoscopic improvement have a high rate of clinical relapse over time. Histologic activity is a predictor of clinical relapse.

Dysregulation of Copper Metabolism in a Patient With Acute-on-Chronic Liver Failure Worked up for Fulminant Wilson Disease.

Wilson disease (WD) is estimated present in 6%-12% of patients younger than 40 years hospitalized with acute liver failure (ALF). Fulminant WD carries a poor prognosis without treatment. A 36-year-old man with HIV, chronic hepatitis B virus, and alcohol use had ceruloplasmin 6.4 mg/dL and 24-hour urine copper 180 µg/L. WD workup was otherwise negative, including ophthalmic examination, hepatic copper quantification, ATP7B sequencing, and brain MRI. ALF commonly features copper dysregulation. Few studies on WD biomarkers have included fulminant WD. Our patient with WD biomarkers and other causes of liver failure highlights the need to study copper dysregulation in ALF.

Immunotherapy for Hepatocellular Carcinoma in the Setting of Liver Transplantation: A Review.

The emerging field of immuno-oncology has brought exciting developments in the treatment of hepatocellular carcinoma (HCC). It has also raised urgent questions about the role of immunotherapy in the setting of liver transplantation, both before and after transplant. A growing body of evidence points to the safety and efficacy of immunotherapeutic agents as potential adjuncts for successful down-staging of advanced HCCs to allow successful transplant in carefully selected patients. For patients with recurrent HCC post-transplant, immunotherapy has a limited, yet growing role. In this review, we describe optimal regimens in the setting of liver transplantation.

Viral hepatitis elimination challenges in low- and middle-income countries-Uzbekistan Hepatitis Elimination Program (UHEP).

BACKGROUND & AIMS: Chronic infection with hepatitis B and C viruses (HBV & HCV) is a major contributor to liver disease and liver-related mortality in Uzbekistan. There is a need to demonstrate the feasibility of large-scale simplified testing and treatment to implement a national viral hepatitis elimination program. METHODS: Thirteen polyclinics were utilized to screen, conduct follow-up biochemical measures and treat chronic HBV and HCV infection in the general adult population. Task shifting and motivational interviewing training allowed nurses to provide rapid screening and general practitioners (GPs) to treat individuals on-site. An electronic medical system tracked individuals through the cascade of care. RESULTS: The use of rapid tests allowed for screening of 60 769 people for HCV and HBV over 6 months and permitted outdoor testing during the COVID-19 pandemic along with COVID testing. 13%-14% of individuals were lost to follow-up after the rapid test, and another 62%-66% failed to come in for their consultation. One stop testing and treatment did not result in a statistically increase in retention and lack of patient awareness of viral hepatitis was identified as a key factor. Despite training, there were large differences between GPs and patients initiating treatment. CONCLUSIONS: The current study demonstrated the feasibility of large-scale general population screening and task shifting in low- and middle-income countries. However, such programs need to be proceeded by awareness campaign to minimize loss to follow up. In addition, multiple trainings are needed for GPs to bolster their skills to talk to patients about treatment.

Transplant in acute alcoholic hepatitis: a relative contraindication.

PURPOSE OF REVIEW: The aim of this review is to provide a critical analysis of liver transplantation for alcoholic hepatitis, with an emphasis on barriers to long-term success in current implementation strategies across the United States. RECENT FINDINGS: Alcohol-associated liver disease is the most rapidly increasing indication for liver transplantation in the USA. Its most severe form, acute alcoholic hepatitis, has a rising incidence particularly in the young, and is associated with a high mortality risk. Although excellent outcomes following liver transplantation for alcoholic hepatitis can be achieved, several barriers limit its routine use. These constraints include risk of allograft dysfunction, the recognition of alcohol use disorder as a multisystem disease and ethical considerations. SUMMARY: Although liver transplantation is an important option in a carefully selected group of candidates, it should not be considered the standard of care in this condition. Consistency, transparency and consensus are necessary to formulate and implement policy changes at the national level. Following liver transplantation, wraparound services are important for relapse prevention, and to ensure long-term success and survival in this challenging group of patients.

Characterization of Mycophenolate Mofetil Gastrointestinal Toxicity and Risk Factors for Severe Disease and Poor Prognosis.

Authors performed a chart review to identify cases of mycophenolate mofetil gastrointestinal toxicity at our institution. In this cohort, friability was associated with severe disease; and nausea and erythema were associated with poor prognosis.

Higher Levels of Fibrosis in a Cohort of Veterans with Chronic Viral Hepatitis are Associated with Extrahepatic Cancers.

BACKGROUND AND AIMS: An estimated 2.4 million Americans, including more than 150,000 veterans, are chronically infected with hepatitis C virus (HCV). HCV is estimated to cause roughly 25% of all hepatocellular carcinoma. Although its mechanism is unknown, developing evidence suggests that chronic HCV infection is also associated with the development of extrahepatic cancers (EHCs). This paper aims to assess the relationship of hepatic fibrosis and chronic HCV with the risk of developing EHC. METHODS: We conducted a single-center retrospective chart review of 1541 patients linked to the hepatitis clinic at the Veterans Affairs (VA) Maryland Health Care System who underwent transient elastography for evaluation and management of liver disease from 2014 to 2018. Liver fibrosis was measured using ultrasound and transient elastography. Extrahepatic cancer and site was identified by a retrospective chart review. RESULTS: In adjusted analysis of EHCs, advanced age (OR: 1.97, 95% CI: 1.30-3.04), and higher measured stiffness (OR 2.19, 95% CI: 1.32-3.64) were associated with an increased likelihood of developing EHC, controlling for HBV infection, HCV exposure, heavy alcohol use, and body mass index. CONCLUSIONS: We observed a significant association between increasing age and increasing levels of liver fibrosis with increased risk of EHC, notably prostate, head and neck squamous cell, lung, and hematologic cancers.

Nonalcoholic Fatty Liver Disease Is Common in IBD Patients However Progression to Hepatic Fibrosis by Noninvasive Markers Is Rare.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the most common liver disorder in western countries and an increasing cause of end-stage liver disease and hepatocellular carcinoma. NAFLD is known to coexist in patients with inflammatory bowel disease (IBD). This study aims to examine the prevalence of NAFLD, as well as trends in NAFLD-associated fibrosis, in a well-characterized IBD cohort utilizing a validated noninvasive test. METHODS: We conducted a single-center retrospective chart review of patients at a large academic IBD center between 2007 and 2017. Patients with IBD and concurrent hepatic steatosis were identified. Charts were reviewed for baseline characteristics and laboratory data in order to calculate and trend NAFLD progression over time by a noninvasive marker, the NAFLD fibrosis score (NFS). RESULTS: Of 207 patients with IBD and concurrent NAFLD, NFS was able to be calculated for 138 patients at index diagnosis. A subsequent NFS was able to be calculated at 5-year follow-up for 56 patients. Over 5 years, 9 patients (16%) had worsening in NFS category, 4 patients (7%) had improvement in NFS category, and the remaining 43 patients (77%) stayed within their index NFS category. CONCLUSIONS: IBD patients with NAFLD tend to have stable liver disease over 4-6 years, and the risk of liver disease progression is low. This is the first study to document the progression of NAFLD by noninvasive testing over time.

A Model of Care Optimized for Marginalized Remote Population Unravels Migration Pattern in India.

BACKGROUND AND AIMS: Access to basic health needs remains a challenge for most of world's population. In this study, we developed a care model for preventive and disease-specific health care for an extremely remote and marginalized population in Arunachal Pradesh, the northeasternmost state of India. APPROACH AND RESULTS: We performed patient screenings, performed interviews, and obtained blood samples in remote villages of Arunachal Pradesh through a tablet-based data collection application, which was later synced to a cloud database for storage. Positive cases of hepatitis B virus (HBV) were confirmed and genotyped in our central laboratory. The blood tests performed included liver function tests, HBV serologies, and HBV genotyping. HBV vaccination was provided as appropriate. A total of 11,818 participants were interviewed, 11,572 samples collected, and 5,176 participants vaccinated from the 5 westernmost districts in Arunachal Pradesh. The overall hepatitis B surface antigen (HBsAg) prevalence was found to be 3.6% (n = 419). In total, 34.6% were hepatitis B e antigen positive (n = 145) and 25.5% had HBV DNA levels greater than 20,000 IU/mL (n = 107). Genotypic analysis showed that many patients were infected with HBV C/D recombinants. Certain tribes showed high seroprevalence, with rates of 9.8% and 6.3% in the Miji and Nishi tribes, respectively. The prevalence of HBsAg in individuals who reported medical injections was 3.5%, lower than the overall prevalence of HBV. CONCLUSIONS: Our unique, simplistic model of care was able to link a highly resource-limited population to screening, preventive vaccination, follow-up therapeutic care, and molecular epidemiology to define the migratory nature of the population and disease using an electronic platform. This model of care can be applied to other similar settings globally.

Short-duration treatment with the novel non-nucleoside inhibitor CDI-31244 plus sofosbuvir/velpatasvir for chronic hepatitis C: An open-label study.

Combination regimens of direct-acting antiviral agents (DAAs) for chronic genotype 1 hepatitis C virus (HCV) infection given for 8 or 12 weeks have high cure rates. Shortened treatment durations that maintain high cure rates may lessen treatment barriers related to affordability and drug adherence. We enrolled 12 treatment-naïve adults with chronic genotype 1 HCV infection without cirrhosis in a single-center, open-label trial to receive 2 weeks of the highly potent and selective non-nucleoside inhibitor (NNI) CDI-31244 concurrent with 6 weeks of sofosbuvir/velpatasvir. The main efficacy endpoints were sustained virologic response at 12 (SVR12) and 24 (SVR24) weeks after treatment completion. In all patients, plasma HCV RNA levels rapidly decreased during the first 2 days of treatment and were below the lower limit of quantification by the end of the 6-week treatment period. Eight of 12 (67%) patients achieved both SVR12 and SVR24. Four patients had virological relapse at Week 10, 4 weeks after end of treatment. The most common adverse event was headache, occurring in five (42%) patients. Pharmacokinetic analysis showed no relevant drug interactions between CDI-31244, sofosbuvir, and velpatasvir. In this pilot study of short-duration combination therapy involving a novel NNI with a fixed-combination DAA, 8 of 12 treatment-naïve patients with chronic genotype 1 HCV infection without cirrhosis achieved virologic cure. Future trials might evaluate whether extending the NNI duration beyond 2 weeks with combination DAAs results in higher cure rates comparable with currently approved longer duration therapy.

Hepatitis A: Epidemiology, Natural History, Unusual Clinical Manifestations, and Prevention.

Hepatitis A virus (HAV) is a positive-strand RNA virus that is transmitted feco-orally through person-to-person contact. Outbreaks are often linked to poor sanitation, overcrowding, or food and water contamination. Infection is often asymptomatic in children, but adults present with jaundice, abdominal pain, hepatitis, and hyperbilirubinemia. Diagnosis is through detection of immunoglobulin M antibodies against HAV, and treatment is supportive. Vaccination is the mainstay of prevention and should be given before exposure whenever possible.

TELEmedicine for Patients With Inflammatory Bowel Disease (TELE-IBD) Does Not Improve Depressive Symptoms or General Quality of Life Compared With Standard Care at Tertiary Referral Centers.

BACKGROUND: Depression is common in patients with inflammatory bowel disease (IBD) and contributes to poor quality of life (QoL). The use of information technology for the remote management of patients with IBD is growing, but little is known about its impact on depressive symptoms (DS) and QoL. We aimed to evaluate the impact of telemedicine on DS and generic QoL in IBD patients. METHODS: We analyzed data from the Telemedicine for Patients with IBD (TELE-IBD) study. During this 12-month clinical trial, patients were randomized to receive text message-based telemedicine weekly (TELE-IBD W), every other week (TELE-IBD EOW), or to standard care. Depressive symptoms and QoL were assessed over time with the Mental Health Inventory 5 (MHI-5) and the Short Form 12 (SF-12), respectively. We compared the change in MHI-5 and SF-12 (with separate physical (PCS) and mental component summary (MCS) scores) between the study arms. RESULTS: A total of 217 participants were included in this analysis. After 1 year, there was no significant difference in the change in MHI-5 (TELE-IBD W +3.0 vs TELE-IBD EOW +0.7 vs standard care +3.4; P = 0.70), MCS (TELE-IBD W +1.4 vs TELE-IBD EOW +1.0 vs standard care +2.5; P = 0.89), and PCS scores (TELE-IBD W +0.4 vs TELE-IBD EOW +0.6 vs standard care +3.7; P = 0.06) between the groups. CONCLUSIONS: Text message-based telemedicine does not improve DS or QoL when compared with standard care in IBD patients treated at tertiary referral centers. Further studies are needed to determine whether telemedicine improves DS or QoL in settings with few resources.

Effect of TELEmedicine for Inflammatory Bowel Disease on Patient Activation and Self-Efficacy.

INTRODUCTION: Limitations in inflammatory bowel disease (IBD) care necessitate greater patient activation and self-efficacy, measures associated with positive health outcomes. METHODS: We assessed change in patient activation and general self-efficacy from baseline to 12 months through our TELEmedicine for IBD trial, a multicenter, randomized controlled trial consisting of a web-based monitoring system that interacts with participants via text messaging. A total of 222 adults with IBD who had experienced an IBD flare within 2 years prior to the trial were randomized into either a control arm that received standard care (SC) or an intervention arm that completed self-testing through the TELE-IBD system every other week (EOW) or weekly (W). RESULTS: Changes in self-efficacy scores were not significantly different between control and experimental groups. Patient activation scores were significantly different between standard care and the TELE-IBD EOW group only (p = 0.03). CONCLUSIONS: Use of remote monitoring did not improve self-efficacy or patient activation compared to routine care.

Clinical features and determinants of chronicity in hepatitis E virus infection.

Hepatitis E virus (HEV) has traditionally been associated with an acute, self-limiting hepatitis and is not known to have any chronic sequelae. HEV genotypes 1 and 2, which are human pathogens, have been associated with this self-limiting presentation, in both sporadic and epidemic settings. HEV genotype 3, which is zoonotically transmitted, is increasingly being reported as a cause of chronic infection in immunocompromised patients. These include patients with solid organ transplants, patients receiving chemotherapy for haematologic malignancies and patients infected with HIV. Chronic infection is associated with rapidly progressing liver disease and extrahepatic manifestations including neurologic disorders. We review the clinical manifestations of chronic HEV infection and discuss factors determining persistence and chronicity of HEV.
