RESUMEN
BACKGROUND AND AIMS: Patients often refer to bowel preparation and associated dietary restrictions as the greatest deterrents to having a colonoscopy completed or performed. Large studies comparing a low-residue diet (LRD) and a clear liquid diet (CLD) are still limited. The aim of this study is to compare LRD and CLD with regard to bowel preparation quality, tolerance, and satisfaction among a diverse patient population. METHODS: This study is a dual-center, randomized, single-blinded, prospective trial involving adult patients undergoing outpatient colonoscopy at the University of California Irvine Medical Center and an affiliated Veterans Administration hospital. Patients were randomized to consume either a CLD or a planned LRD for the full day prior to colonoscopy. Both groups consumed 4L split-dosed PEG-ELS. The adequacy of bowel preparation was evaluated using the Boston Bowel Preparation Score (BBPS). Adequate preparation was defined as a BBPS ≥ 6 with no individual segment less than a score of 2. Hunger and fatigue pre - and post-procedure were graded on a ten-point scale. Nausea, vomiting, bloating, abdominal cramping, overall discomfort, satisfaction with the diet, willingness to repeat the same preparation and overall experience were assessed. RESULTS: A total of 195 subjects who underwent colonoscopy from October 2014 to October 2017 were included. The mean BBPS for the LRD and CLD groups was 8.38 and 7.93, respectively (p = 0.1). There was a significantly higher number of adequate preparations in the LRD group compared to CLD (p = 0.05). Evening hunger scores just before starting the bowel preparation were significantly lower in the LRD than the CLD group, 2.81 versus 5.97, respectively (p = 0.006). Subjects in the LRD group showed significantly less nausea (p = 0.047) and bloating (p = 0.04). Symptom scores for vomiting, abdominal cramping, and overall discomfort were similar between the groups. Satisfaction with diet was significantly higher in the LRD group than CLD, 72% versus 37.66%, respectively (p < 0.001). The overall colonoscopy experience and the satisfaction with the preparation itself were also better reported in the LRD group (p < 0.001 and p = 0.002, respectively). CONCLUSIONS: This study, which included a diverse group of patients, demonstrated that patients using a LRD before colonoscopy achieve a bowel preparation quality that is superior to patients on a CLD restriction. This study shows that a low-residue diet improves patient satisfaction and results in significantly better tolerability of bowel preparation. As a less restrictive dietary regimen, the low-residue diet may help improve patient participation in colorectal cancer screening programs.

BACKGROUND: Cigarette smoking is thought to increase the risk of Crohn's disease (CD) and exacerbate the disease course, with opposite roles in ulcerative colitis (UC). However, these findings are from Western populations, and the association between smoking and inflammatory bowel disease (IBD) has not been well studied in Asia. AIMS: We aimed to compare the prevalence of smoking at diagnosis between IBD cases and controls recruited in China, India, and the USA, and to investigate the impact of smoking on disease outcomes. METHODS: We recruited IBD cases and controls between 2014 and 2018. All participants completed a questionnaire about demographic characteristics, environmental risk factors and IBD history. RESULTS: We recruited 337 participants from China, 194 from India, and 645 from the USA. In China, CD cases were less likely than controls to be current smokers (adjusted odds ratio [95% CI] 0.4 [0.2-0.9]). There was no association between current or former smoking and CD in the USA. In China and the USA, UC cases were more likely to be former smokers than controls (China 14.6 [3.3-64.8]; USA 1.8 [1.0-3.3]). In India, both CD and UC had similar current smoking status to controls at diagnosis. Current smoking at diagnosis was significantly associated with greater use of immunosuppressants (4.4 [1.1-18.1]) in CD cases in China. CONCLUSIONS: We found heterogeneity in the associations of smoking and IBD risk and outcomes between China, India, and the USA. Further study with more adequate sample size and more uniform definition of smoking status is warranted.

BACKGROUND & AIMS: Mobile health technologies are advancing rapidly as smartphone use increases. Patients with inflammatory bowel disease (IBD) might be managed remotely through smartphone applications, but no tools are yet available. We tested the ability of an IBD monitoring tool, which can be used with mobile technologies, to assess disease activity in patients with Crohn's disease (CD) or ulcerative colitis (UC). METHODS: We performed a prospective observational study to develop and validate a mobile health index for CD and UC, which monitors IBD disease activity using patient-reported outcomes. We collected data from disease-specific questionnaires completed by 110 patients with CD and 109 with UC who visited the University of California, Los Angeles, Center for IBD from May 2013 through January 2014. Patient-reported outcomes were compared with clinical disease activity index scores to identify factors associated with disease activity. Index scores were validated in 301 patients with CD and 265 with UC who visited 3 tertiary IBD referral centers (in California or Europe) from April 2014 through March 2015. RESULTS: We assessed activity of CD based on liquid stool frequency, abdominal pain, patient well-being, and patient-assessed disease control, and activity of UC based on stool frequency, abdominal pain, rectal bleeding, and patient-assessed disease control. The indices identified clinical disease activity with area under the receiver operating characteristic curve values of 0.90 in patients with CD and 0.91 in patients with UC. They identified endoscopic activity with area under the receiver operating characteristic values of 0.63 in patients with CD and 0.82 in patients with UC. Both scoring systems responded to changes in disease activity (P < .003). The intraclass correlation coefficient for test-retest reliability was 0.94 for CD and for UC. CONCLUSIONS: We developed and validated a scoring system to monitor disease activity in patients with CD and UC that can be used with mobile technologies. The indices identified clinical disease activity with area under the receiver operating characteristic curve values of 0.9 or higher in patients with CD or UC, and endoscopic activity in patients with UC but not CD.

OBJECTIVES: Symptoms of and treatments for inflammatory bowel disease (IBD) have a significant impact on patients' quality of life (QOL) and result in an increased prevalence of depression and anxiety disorders. Little is known about the type of coping strategies used by adult patients with IBD to better cope with their chronic illness, however. The objectives of this study were to identify the types of coping styles and their impact on the QOL of patients with IBD. METHODS: The first 150 consecutive participants with IBD were recruited at five major tertiary hospitals and given an anonymous survey consisting of demographic information, the Jalowiec Coping Scale, and the Shortened Inflammatory Bowel Disease Questionnaire. RESULTS: The cohort was 51.3% men and included 150 participants with a mean age of 39.3 years. The primary coping mechanisms used were confrontive (46.7%), evasiveness (30.0%), optimistic (18.7%), and fatalistic (4.6%) coping. Participants rated confrontive (62.0%), optimistic (26.6%), and evasive (11.4%) coping styles as the most effective. Those who reported an increased frequency of flares scored lower on QOL (P <0.05) and more often used evasive and fatalistic coping styles (P < 0.05) compared with other coping strategies; however, after controlling for disease activity, QOL was significantly better for those who primarily used adaptive coping styles compared with those who used maladaptive styles (P <0.001). CONCLUSIONS: We demonstrated that confrontive, evasive, and optimistic styles of coping are most widely used among patients with IBD. Despite controlling for disease activity, we demonstrated that those who used adaptive coping styles had a higher QOL compared with those who used maladapative coping styles. Future research on coping is warranted to assess coping styles on therapeutic compliance and disease perception.

AIMS: To define the patterns of Internet use among physicians who treat inflammatory bowel disease (IBD) and physicians' perceptions of their patients' Internet use. METHODS: An online survey about physician and patient use of the Internet was created and e-mailed to gastroenterologists nationwide. Surveys were distributed and collected via an online database and a subsequent statistical analysis was performed. RESULTS: Of the 1000 e-mail invitations sent to practicing gastroenterologists in the United States, 223 participants (22.3%) completed the survey. A total of 183 (82.1%) physicians reported using an Internet-based reference to assist them in deriving management strategies for their patients with IBD, with the most commonly utilized resource being UpToDate followed by PubMed and the Crohn's and Colitis Foundation of America Web site. Although nearly 80% of gastroenterologists believed that using the Internet helped them facilitate clinical discussions, 183 participants (82.1%) believed that inaccurate information found online could sometimes result in increased clinic time because physicians must spend more time dispelling misleading information. CONCLUSIONS: Despite a study design biased toward selecting gastroenterologists who commonly used the Internet, we demonstrated that only 60% of the providers routinely refer their patients to the Internet. This underscores the fact that it is important to have a centralized "physician-certified" online resource to which physicians could readily refer their patients to navigate through various disease-specific resources without concern that their patients are receiving unreliable or misleading information.

Gastroenterologists encounter many nutrition-related disorders in their practice, yet the nutritional needs of patients with chronic gastrointestinal (GI) and liver disease are largely unaddressed by treating physicians, due to suboptimal nutrition education. To address this gap, we developed and piloted a culinary medicine course for a GI fellowship training program. The objective of this study is to describe the development, implementation, and acceptability of the course. A registered dietitian, a chef instructor, and a gastroenterology clinical professor trained in culinary medicine developed the four-class tailored curriculum and delivered the classes remotely. Each class had a theme related to commonly encountered GI disorders and included hands-on meal preparation, a nutrition lecture, and a patient case study discussion. Post-course feedback surveys were disseminated. Twenty-three GI physicians enrolled in the course and the attendance rates in classes 1-4 were 83%, 65%, 61%, and 48%, respectively. Among 15 completed feedback surveys, 80% reported that the class contents were either moderately or extremely useful and all endorsed the curriculum for other gastroenterologists. Future studies of culinary medicine programs tailored to medical specialties should identify strategies to maintain engagement and assess the impact on nutrition knowledge, competencies, and translation of these new skills to clinical practice.

Background: Hands-on culinary medicine education for medical trainees has emerged as a promising tool for cardiovascular health promotion. Purpose: To determine whether virtual culinary medicine programming associates with Mediterranean diet (MedDiet) adherence and lifestyle medicine competencies among medical trainees across the USA. Method: A total of 1433 medical trainees across 19 sites over a 12-month period were included. The Cooking for Health Optimisation with Patients-Medical Trainees survey composed of 61 questions regarding demographics, nutritional attitudes, dietary habits including MedDiet score and lifestyle medicine counselling competencies. Multivariable logistic regression assessed the association of virtual culinary medicine education with MedDiet intake and nutritional attitudes. Results: There were 519 medical trainees who participated in virtual culinary medicine education and 914 medical trainees who participated in their standard nutrition curricula. More than one-half of participants were women (n=759) and the mean age was 27 years old. Compared with students enrolled in traditional nutrition curricula, participants in virtual culinary medicine education were 37% more likely to adhere to MedDiet guidelines for fruit intake (OR 1.37, 95% CI 1.03 to 1.83, p=0.03). Virtual culinary medicine education was associated with higher proficiency in lifestyle medicine counselling categories, notably recommendations involving fibre (OR 4.03; 95% CI 3.05 to 5.34), type 2 diabetes prevention (OR 4.69; 95% CI 3.51 to 6.27) and omega fatty acids (OR 5.21; 95% CI 3.87 to 7.02). Virtual culinary medicine education had a similar, although higher magnitude association with MedDiet counselling competency (OR 5.73, 95% CI 4.26 to 7.70) when compared with historical data previously reported using hands-on, in-person culinary medicine courseware (OR 4.97, 95% CI 3.89 to 6.36). Conclusions: Compared with traditional nutritional educational curricula, virtual culinary medicine education is associated with higher MedDiet adherence and lifestyle medicine counselling competencies among medical trainees. Both virtual and hands-on culinary medicine education may be useful for cardiovascular health promotion.
RESUMEN
Previous studies assessing efficacy of support groups for patients with inflammatory bowel disease showed mixed results in terms of attendance and overall effectiveness. In this study, researchers evaluated the use of an ongoing open psychoeducational support group for adult patients with inflammatory bowel disease in an outpatient tertiary setting. The sample consisted of 18 adults who have attended more than 2 meetings of the support group. Topics addressed in the support group include complementary medicine, diet and nutrition, the psychological impact of inflammatory bowel disease, medication and side effects, and insurance/disability. Participants were asked to complete the Client Satisfaction Questionnaire, Multidimensional Support Scale, 11 general demographic questions, and a brief open-ended qualitative questionnaire developed by the researchers. Results demonstrated that participants reported very high satisfaction with the support group and rated the adequacy of peer support from others with inflammatory bowel disease higher than support from family/friends and professionals. A majority of group members reported joining the group for mutual support and education; this expectation was met through the psychoeducational structure of the group. This study demonstrates the potential for success of an ongoing psychoeducational inflammatory bowel disease support group for adult patients and their caregivers.

Anti-tumor necrosis factor (TNF) biologics are currently amongst the most widely used and efficacious therapies for inflammatory bowel disease (IBD). The development of therapeutic drug monitoring for infliximab and adalimumab has allowed for measurement of drug levels and antidrug antibodies. This information can allow for manipulation of drug therapy and prediction of response. It has been shown that therapeutic anti-TNF drug levels are associated with maintenance of remission, and development of antidrug antibodies is predictive of loss of response. Studies suggest that a low level of drug antibodies, however, can at times be overcome by dose escalation of anti-TNF therapy or addition of an immunomodulator. We describe a retrospective case series of twelve IBD patients treated at the University of California-Irvine, who were on infliximab or adalimumab therapy and were found to have detectable but low-level antidrug antibodies. These patients underwent dose escalation of the drug or addition of an immunomodulator, with subsequent follow-up drug levels obtained. Eight of the twelve patients (75%) demonstrated resolution of antidrug antibodies, and were noted to have improvement in disease activity. Though data regarding overcoming low-level anti-TNF drug antibodies remains somewhat limited, cases described in the literature as well as our own experience suggest that this may be a viable strategy for preserving the use of an anti-TNF drug. Low-level anti-TNF drug antibodies may be overcome by dose escalation and/or addition of an immunomodulator, and can allow for clinical improvement in disease status. Therapeutic drug monitoring is an important tool to guide this strategy.
RESUMEN
BACKGROUND: While previous studies have evaluated caregivers' quality of life (QOL), burnout, and stress amongst across a variety of chronic illnesses, few such studies have been related to inflammatory bowel disease (IBD). METHODS: Caregivers accompanying adult patients with IBD at 6 tertiary centers were enrolled. They completed self-administered surveys related to QOL and burden, including the QOL scale, Zarit Burden Interview (ZBI), and Brief COPE. RESULTS: Of the 200 consecutive caregivers asked to participate, 162 (81.0%) enrolled and completed the survey. A total of 43.8% caregivers reported having a high level of burden as measured by the ZBI. Factors predictive of a high burden included female gender, younger age of caregiver, household income <$30,000, having more than one dependent in the household, caring for a patient with active disease and higher disease severity, and a personal history of psychiatric illness. Over one third of the caregivers reported a maladaptive coping pattern. The caregiver factors predictive of maladaptive coping skills included male gender, lack of involvement in a support group, a personal history of psychiatric illness, and living in a different household from the patient. CONCLUSIONS: A large proportion of caregivers of IBD patients experience a high level of caregiver burden and reduced QOL. Participation in religious/spiritual activities and support groups appeared to reduce perceived caregiver burden and improve QOL. This study suggests there is an unmet need to address the caregiver burden of adult IBD patients.
RESUMEN
Discerning drug hepatotoxicity from viral hepatitis flares remains an ongoing problem unique to patients coinfected with HIV and hepatitis B (HBV). We present three such coinfected patients who have been on two anti-HBV agents, lamivudine and tenofovir disoproxil fumarate simultaneously, as part of highly active antiretroviral therapy (HAART). All three developed significant aminotransferase elevations 6-12 weeks after initiation of HAART despite being on two active HBV drugs. Two of the three patients were initially thought to have drug-related hepatotoxicity from HIV medications. It seems more likely that all three patients demonstrated hepatitis B reactivation of differing severity as the result of varying degrees of immune recovery. Distinguishing clearly between drug-related hepatotoxicity and hepatitis reactivation may be difficult but is important as their clinical management differs.

Since the approval of the first anti-tumor necrosis factor (anti-TNF) therapy in late 1998, the treatment for Crohn's disease (CD) has been revolutionized. Anti-TNF therapy has been consistently shown in numerous clinical trials to be effective for patients with more aggressive perianal, internal penetrating, and fistulizing CD. However, the loss of clinical remission is frequent and only one-third of patients remain in clinical remission at 1 year. The pharmacokinetics of anti-TNF is highly variable among patients and could be influenced by many factors including serum albumin, gender, body weight, systemic inflammation and route of administration. The main factor impacting anti-TNF pharmacokinetics and efficacy is the development of immunogenicity where antidrug antibodies accelerate anti-TNF drug clearance. In this review paper, we evaluate the role of combination therapy with anti-TNF drugs and immunomodulators, the role of therapeutic drug monitoring, and strategies to recapture loss of clinical response in order to improve both short- and long-term outcomes in CD patients.
RESUMEN
Confocal laser-induced endomicroscopy (CLE), first introduced in 2003, allows the capture of images of "virtual histology" of the gastrointestinal mucosa during endoscopy, providing the opportunity to retrieve real-time visualization of the pathology of the mucosal epithelium with its cellular and subcellular structures. This new endoscopic imaging technique serves as an adjunctive diagnostic tool to the traditional ileocolonoscopy in the management of inflammatory bowel disease (IBD) patients. In multiple clinical trials, CLE has been shown to improve detection of dysplasia, assess disease activity, predict future clinical relapses, and assess potential responsiveness to anti-tumor necrosis factor therapy. This review explores in depth the current and future role of CLE in the management of IBD patients.
RESUMEN
BACKGROUND: Intestinal tuberculosis can closely mimic Crohn's disease and colon cancer. Presented here is a case of intestinal tuberculosis that closely mimicked both. CASE REPORT: A 23 year old Hispanic female presented with several months of weight loss, recurrent fever, and emesis. The patient did not have pulmonary symptoms or radiographic evidence of tuberculosis. Colonoscopy evaluation with biopsy of the affected bowel segments were thought to be consistent with either colon cancer or Crohn's Disease. Acid fast bacilli staining and histological analysis did not display evidence of tuberculosis on two separate occasions. The patient developed colonic obstruction acutely during the course of treatment requiring resection of the affected bowel segment. Acid fast staining of the resected lymph nodes was positive and submucosal caseating granulomas were identified histologically, consistent with intestinal tuberculosis. CONCLUSIONS: Intestinal tuberculosis remains a diagnostic challenge. Consideration of the disease should be maintained in equivocal cases.
RESUMEN
UNLABELLED: Although rare instances of cardiac injury or arrhythmias have been reported in acute liver failure (ALF), overall, the heart is considered to be spared in this condition. Troponin I, a sensitive and specific marker of myocardial injury, may be elevated in patients with sepsis and acute stroke without underlying acute coronary syndrome, indicating unrecognized cardiac injury in these settings. We sought to determine whether subclinical cardiac injury might also occur in acute liver failure. Serum troponin I levels were measured in 187 patients enrolled in the US Acute Liver Failure Study Group registry, and correlated with clinical variables and outcomes. Diagnoses were representative of the larger group of >1000 patients thus far enrolled and included 80 with acetaminophen-related injury, 26 with viral hepatitis, 19 with ischemic injury, and 62 others. Overall, 74% of patients had elevated troponin I levels (>0.1 ng/ml). Patients with elevated troponin I levels were more likely to have advanced hepatic coma (grades III or IV) or to die (for troponin I levels >0.1 ng/ml, odds ratio 3.88 and 4.69 for advanced coma or death, respectively). CONCLUSION: In acute liver failure, subclinical myocardial injury appears to occur more commonly than has been recognized, and its pathogenesis in the context of acute liver failure is unclear. Elevated troponin levels are associated with a significant increase in morbidity and mortality. Measurement of troponin I levels may be helpful in patients with acute liver failure, to detect unrecognized myocardial damage and as a marker of unfavorable outcome.
