Cutaneous Crohn disease presenting as "knife-edged" ulcers: a case report.

BACKGROUND: CCD presents as non-caseating granulomas within the skin at a site distant from the GI tract. CCD is a debilitating extraintestinal sequela of CD that can sometimes precede its GI manifestations. In the absence of GI symptoms, the histopathologic and clinical features of CCD can present as a variety of inflammatory skin conditions that can range from ruptured follicle-associated granulomas to cutaneous ulcerations. While a variety of therapeutic options for patients with CCD and concurrent luminal CD have been described in the literature, there is no standard treatment algorithm for the management of refractory CCD with limited or covert GI involvement. CASE REPORT: The authors discuss the case of a 33-year-old female who presented to the wound care clinic with multiple "knife-edged" cutaneous ulcerations involving the intertriginous spaces, found to be consistent with CCD. Her original cutaneous symptoms and diagnosis manifested with minimal GI involvement and responded to IVIG treatment. CONCLUSIONS: This case supports the inclusion of CCD in the differential diagnosis in patients with knife-edged granulomatous skin lesions in intertriginous locations. This clinical condition may present in the setting of no or limited GI symptoms. The management of CCD and a proposed treatment algorithm are also presented.

Cutaneous Crohn's disease after proctocolectomy for medically refractory colonic Crohn's disease: a case series and review of the literature.

Background: Cutaneous Crohn's disease (CCD), also known as metastatic Crohn's disease (CD), is one of the rarest and most challenging cutaneous manifestations of CD. It is characterized by non-caseating granulomatous inflammation of the skin at sites that are non-contiguous with the gastrointestinal (GI) tract. Diagnosis of CCD needs a high clinical suspicion since morphological presentation varies widely and lacks an apparent correlation to the activity of the luminal CD. The onset of CCD in patients without active GI CD is a particularly understudied phenomenon. Methods: We present a case series of a unique patient group who developed CCD while in remission from a luminal CD perspective, mainly after a proctocolectomy for Crohn's colitis. We also provide a literature review and summary of case reports of CCD after proctocolectomy. Results: Our 4 adult patients diagnosed with CCD after proctocolectomy presented herein, were successfully treated with high-dose corticosteroids, followed by biologic therapy. Furthermore, a comprehensive review of CCD is provided regarding its pathogenesis, clinical presentation, differential diagnosis, and the evidence behind the available treatments. Conclusions: CCD should be considered in any CD patient presenting with skin lesions regardless of their disease activity status and history of proctocolectomy. The treatment remains challenging; biologics remain the cornerstone and a multidisciplinary approach is recommended. Larger randomized clinical trials are essential to determine the optimal treatment protocol and to improve outcomes.

Epidemiology of irritable bowel syndrome in hospitalized patients with inflammatory bowel disease: Nationwide Inpatient Sample analysis from 2007-2016.

Background: Despite effective treatments for inflammatory bowel disease (IBD), patients in remission may still suffer from gastrointestinal symptoms attributable to overlying irritable bowel syndrome (IBS). In this population-based cohort study, we investigated the epidemiology of IBS in hospitalized IBD patients and explored the differences between hospitalized IBD-IBS vs. IBD patients to distinguish this patient population. Methods: Using the Nationwide Inpatient Sample database from 2007-2016, we identified patients with a primary or secondary discharge diagnosis of IBD, with or without IBS, using ICD-9 and ICD-10 codes. We extracted information on demographics, psychological comorbidities, IBD complications, cost and duration of stay of each group, from either discharge records or diagnosis codes. These were analyzed using SAS version 4.0. Results: There was a rise in the prevalence of IBS among inpatients with ulcerative colitis (P=0.025) and Crohn's disease (P=0.0014) over the study period. This study revealed that IBD patients with IBS tend to be female, younger, are less likely to be morbidly obese and have higher rates of psychological disorders (P<0.001) compared to IBD patients with no IBS co-diagnosis. They also have fewer IBD-specific complications, such as strictures, obstruction, fistula and abdominal abscess (P<0.001). Shorter hospital stays (P<0.001) and lower hospital charges (P<0.001) were also noted in these patients. Conclusions: IBD patients with IBS are significantly different from other IBD patients, and are associated with less severe disease, a shorter hospital stay and lower hospital expenses. Early and accurate classification of this patient population may prevent unnecessary treatment and hospitalization in the future.

Opioid-related emergency department visits and hospitalizations among patients with chronic gastrointestinal symptoms and disorders dually enrolled in the Department of Veterans Affairs and Medicare Part D.

PURPOSE: We examined the prevalence of, and factors associated with, serious opioid-related adverse drug events (ORADEs) that led to an emergency department (ED) visit or hospitalization among patients with chronic gastrointestinal (GI) symptoms and disorders dually enrolled in the Department of Veterans Affairs (VA) and Medicare Part D. METHODS: In this retrospective cohort study, we used linked national patient-level data (April 1, 2011, to October 31, 2014) from the VA and Centers for Medicare and Medicaid Services to identify serious ORADEs among dually enrolled veterans with a chronic GI symptom or disorder. Outcome measures included serious ORADEs, defined as an ED visit attributed to an ORADE or a hospitalization where the principal or secondary reason for admission involved an opioid. We used multiple logistic regression models to determine factors independently associated with a serious ORADE. RESULTS: We identified 3,430 veterans who had a chronic GI symptom or disorder; were dually enrolled in the VA and Medicare Part D; and had a serious ORADE that led to an ED visit, hospitalization, or both. The period prevalence of having a serious ORADE was 2.4% overall and 4.4% among veterans with chronic opioid use (≥90 consecutive days). Veterans with serious ORADEs were more likely to be less than 40 years old, male, white, and to have chronic abdominal pain, functional GI disorders, chronic pancreatitis, or Crohn's disease. They were also more likely to have used opioids chronically and at higher daily doses. CONCLUSION: There may be a considerable burden of serious ORADEs among patients with chronic GI symptoms and disorders. Future quality improvement efforts should target this vulnerable population.

Characteristics of Opioid Prescriptions to Veterans With Chronic Gastrointestinal Symptoms and Disorders Dually Enrolled in the Department of Veterans Affairs and Medicare Part D.

INTRODUCTION: Gastrointestinal (GI) symptoms and disorders affect an increasingly large group of veterans. Opioid use may be rising in this population, but this is concerning from a patient safety perspective, given the risk of dependence and lack of evidence supporting opioid use to manage chronic pain. We examined the characteristics of opioid prescriptions and factors associated with chronic opioid use among chronic GI patients dually enrolled in the DVA and Medicare Part D. MATERIALS AND METHODS: In this retrospective cohort study, we used linked, national patient-level data (from April 1, 2011, to December 31, 2014) from the VA and Centers for Medicare & Medicaid Services to identify chronic GI patients and observe opioid use. Veterans who had a chronic GI symptom or disorder were dually enrolled in VA and Part D and received ≥1 opioid prescription dispensed through the VA, Part D, or both. Chronic GI symptoms and disorders included chronic abdominal pain, chronic pancreatitis, inflammatory bowel diseases, and functional GI disorders. Key outcome measures were outpatient opioid prescription dispensing overall and chronic opioid use, defined as ≥90 consecutive days of opioid receipt over 12 months. We described patient characteristics and opioid use measures using descriptive statistics. Using multiple logistic regression modeling, we generated adjusted odds ratios and 95% CIs to determine variables independently associated with chronic opioid use. The final model included variables outlined in the literature and our conceptual framework. RESULTS: We identified 141,805 veterans who had a chronic GI symptom or disorder, were dually enrolled in VA and Part D, and received ≥1 opioid prescription dispensed from the VA, Part D, or both. Twenty-six percent received opioids from the VA only, 69% received opioids from Medicare Part D only, and 5% were "dual users," receiving opioids through both VA and Part D. Compared to veterans who received opioids from the VA or Part D only, dual users had a greater likelihood of potentially unsafe opioid use outcomes, including greater number of days on opioids, higher daily doses, and higher odds of chronic use. CONCLUSIONS: Chronic GI patients in the VA may be frequent users of opioids and may have a unique set of risk factors for unsafe opioid use. Careful monitoring of opioid use among chronic GI patients may help to begin risk stratifying this group. and develop tailored approaches to minimize chronic use. The findings underscore potential nuances within the opioid epidemic and suggest that components of the VA's Opioid Safety Initiative may need to be adapted around veterans at a higher risk of opioid-related adverse events.

High-Dose Opioid Use Among Veterans with Unexplained Gastrointestinal Symptoms Versus Structural Gastrointestinal Diagnoses.

BACKGROUND: In a cohort of Veterans dually enrolled in the Department of Veterans Affairs (VA) and Medicare Part D, we sought to describe high-dose daily opioid use among Veterans with unexplained gastrointestinal (GI) symptoms and structural GI diagnoses and examine factors associated with high-dose use. METHODS: We used linked national patient-level data from the VA and Centers for Medicare and Medicaid Services (CMS). We grouped patients into 3 subsets: those with unexplained GI symptoms (e.g., chronic abdominal pain); structural GI diagnoses (e.g., chronic pancreatitis); and those with a concurrent unexplained GI symptom and structural GI diagnosis. High-dose daily opioid use levels were examined as a binary variable [≥ 100 morphine milligram equivalents (MME)/day] and as an ordinal variable (50-99 MME/day, 100-119 MME/day, or ≥ 120 MME/day). RESULTS: We identified 141,805 chronic GI patients dually enrolled in VA and Part D. High-dose opioid use was present in 11% of Veterans with unexplained GI symptoms, 10% of Veterans with structural GI diagnoses, and 15% of Veterans in the concurrent GI group. Compared to Veterans with only an unexplained GI symptom or structural diagnosis, concurrent GI patients were more likely to have higher daily opioid doses, more opioid days ≥ 100 MME, and higher risk of chronic use. Factors associated with high-dose use included opioid receipt from both VA and Part D, younger age, and benzodiazepine use. CONCLUSIONS: A significant subset of chronic GI patients in the VA are high-dose opioid users. Efforts are needed to reduce high-dose use among Veterans with concurrent GI symptoms and diagnoses.

Targeted housestaff intervention reduces opioid use without worsening patient-reported pain scores and improves outcomes among patients with IBD: the "IBD pain ladder".

BACKGROUND AND AIMS: Opioid analgesic use is associated with increased mortality, higher readmission rates, and reduced quality of life among patients with inflammatory bowel disease (IBD). With the goal of reducing inpatient opioid use among patients with IBD admitted to our inpatient gastroenterology (GI) service, we designed and implemented a standardized, educational intervention providing analgesic decision support to internal medicine and emergency medicine housestaff at our institution. METHODS: Pre-intervention data was collected from patients admitted during a 9-month period prior to intervention. Post-intervention patients were identified prospectively. The primary outcome was reduction in aggregate inpatient opioid use in oral morphine equivalents per patient. RESULTS: A total of 68 patients with 81 hospitalizations were analyzed. There was no statistically significant difference in baseline admission characteristics between the two groups. Our primary outcome was achieved with a statistically significant reduction in opioid use during hospitalization (43.4 mg vs 7.7 mg; p < 0.01). Secondary outcomes achieved included reduction in new opioid prescriptions upon discharge, reduced hospital length of stay, and reduced 90-day readmission rates. There was no significant difference between patients' pain scores between the two groups. CONCLUSION: We believe this intervention, aimed at housestaff education, provides a roadmap for pain management decision-making in this patient population. It is a readily reproducible strategy that can be widely applied to improve inpatient IBD patient care. Importantly, patient experience and pain scores were unchanged despite lower use of inpatient opioid analgesia, highlighting successful opioid-sparing analgesics in most inpatients with IBD.

Patient Understanding of "Flare" and "Remission" of Inflammatory Bowel Disease.

Patients with inflammatory bowel disease have adopted medical jargon terms of "flare" and "remission," but what they mean by these terms is ill-defined and may have implications for nurse-patient communication and treatment expectancy. The aim of this study was to elicit patients' understanding of "flare" and "remission." Individuals with self-reported inflammatory bowel disease were recruited through social media. A web-based survey, with closed and open-ended questions, was administered. Conventional content analysis was used to evaluate respondents' perceptions of jargon terms. A word cloud was generated to augment analysis by visualization of word use frequency. A majority of the 34 respondents had a symptom-focused understanding and described these terms as alternating states. Various symptoms were understood to signify "flare," which was largely attributed to lifestyle factors. Corroborated by the word cloud, there was rare mention of inflammation or tissue damage. This study demonstrates that an understanding of "flare" and "remission" by patients with inflammatory bowel disease is largely symptom-based. The role of inflammation, medication failure, and targets of inflammatory bowel disease treatment beyond symptom control are not currently well known to patients with inflammatory bowel disease. To create a shared understanding of symptoms and treatment goals between the patient and the nurse, patient education on emerging expectations of inflammatory bowel disease care should be prioritized.

Strategies to Identify and Reduce Opioid Misuse Among Patients with Gastrointestinal Disorders: A Systematic Scoping Review.

BACKGROUND: Scoping reviews are preliminary assessments intended to characterize the extent and nature of emerging research evidence, identify literature gaps, and offer directions for future research. We conducted a systematic scoping review to describe published scientific literature on strategies to identify and reduce opioid misuse among patients with gastrointestinal (GI) symptoms and disorders. METHODS: We performed structured keyword searches to identify manuscripts published through June 2016 in the PubMed MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Scopus, and Web of Science databases to extract original research articles that described healthcare practices, tools, or interventions to identify and reduce opioid misuse among GI patients. The Chronic Care Model (CCM) was used to classify the strategies presented. RESULTS: Twelve articles met the inclusion criteria. A majority of studies used quasi-experimental or retrospective cohort study designs. Most studies addressed the CCM's clinical information systems element. Seven studies involved identification of opioid misuse through prescription drug monitoring and opioid misuse screening tools. Four studies discussed reductions in opioid use by harnessing drug monitoring data and individual care plans, and implementing self-management and opioid detoxification interventions. One study described drug monitoring and an audit-and-feedback intervention to both identify and reduce opioid misuse. Greatest reductions in opioid misuse were observed when drug monitoring, self-management, or audit-and-feedback interventions were used. CONCLUSION: Prescription drug monitoring and self-management interventions may be promising strategies to identify and reduce opioid misuse in GI care. Rigorous, empirical research is needed to evaluate the longer-term impact of these strategies.

Posttransplant Lymphoproliferative Disorder of the Small Bowel as an Unexpected Cause of Iron Deficiency Anemia Decades after Heart Transplantation.

Although rare, gastrointestinal posttransplant lymphoproliferative disorder (PTLD) can lead to abdominal pain or gastrointestinal bleeding in patients with a history of solid-organ transplantation. We describe a case of isolated gastrointestinal PTLD in a patient who presented with acute on chronic iron deficiency anemia 26 years after heart transplant. A comprehensive endoscopic evaluation with video capsule endoscopy and small bowel enteroscopy revealed a large cratered ulceration in the small bowel with abnormal mucosal changes, which led to the diagnosis of PTLD.

Integrating Adolescents and Young Adults into Adult-Centered Care for IBD.

Planned healthcare transition, initiated in pediatric care, is a gradual process aimed at fostering the adolescent patient's disease knowledge and skills with the ultimate objective of preparing patients and families for adult-centered care. The process is critical in inflammatory bowel diseases (IBD) where there is an increased risk of non-adherence, hospitalizations, and emergency department use as young adult patients graduate from pediatric to adult-centered care. While evidence for healthcare transition in IBD is mounting, important gaps remain in the understanding of this process from the perspective of the adult gastroenterologist. This paper summarizes what is known about healthcare transition in IBD and explores the unanswered questions-a conceptual and methodological framework for transition interventions, relevant outcomes that define successful transition, and key stakeholder perspectives. For the adult gastroenterologist managing the young adult patient population, this paper presents the paradigm of "care integration"-a process of ongoing, multi-modality support for the patient, initiated in the adult care setting, with the goal of improving self-management skills and active participation in medical decision-making.

Balancing the risks and benefits of biologic therapy in inflammatory bowel diseases.

INTRODUCTION: The incidence of Inflammatory Bowel Diseases (IBD) is rising and overall epidemiology is changing. Goals of IBD therapy are also fast changing to reflect the concept of mucosal healing. IBD management is increasingly revolving around questions of ideal positioning of biologic therapies. AREAS COVERED: This paper covers important concepts regarding two classes of biologic medications approved for treatment of IBD in the United States - anti-TNF-α agents and lymphocyte-homing antagonists. Topics covered include drug mechanism of action, pharmacokinetic considerations for the clinician including therapeutic drug monitoring, summary of current evidence of drug efficacy in IBD focusing on randomized, controlled trial data. Additionally, nuanced discussion of medication side-effects and adverse reactions is presented. EXPERT OPINION: Paradigms of treatment goals in IBD are changing with increasing focus on mucosal healing. Concomitantly, our understanding of important factors that impact drug pharmacokinetic/pharmacodynamics relationships with biologic agents has increased which will help eventually develop personalized algorithms to optimize the efficacy of these agents. Though direct head-to-head comparisons between these agents are lacking, biologic agents can be considered the safest and most effective therapies introduced for IBD.

Serum 25-Hydroxyvitamin D Levels are not Associated with Adverse Outcomes in Clostridium Difficile Infection.

Clostridium difficile infection (CDI) is a significant source of healthcare-associated morbidity and mortality. This study investigated whether serum 25-hydroxyvitamin D is associated with adverse outcomes from CDI. Patients with CDI were prospectively enrolled. Charts were reviewed and serum 25-hydroxyvitamin D was measured. The primary outcome was a composite definition of severe disease: fever (temperature >38°C), acute organ dysfunction, or serum white blood cell count >15,000 cells/µL within 24-48 hours of diagnosis; lack of response to therapy by day 5; and intensive care unit admission; colectomy; or death within 30 days. Sixty-seven patients were included in the final analysis. Mean (±SD) serum 25-hydroxyvitamin D was 26.1 (±18.54) ng/mL. Severe disease, which occurred in 26 (39%) participants, was not associated with serum 25-hydroxyvitamin D [odds ratio (OR) 1.00; 95% confidence interval (CI) 0.96-1.04]. In the adjusted model for severe disease only serum albumin (OR 0.12; 95%CI 0.02-0.64) and diagnosis by detection of stool toxin (OR 5.87; 95%CI 1.09-31.7) remained independent predictors. We conclude that serum 25-hydroxyvitamin D is not associated with the development of severe disease in patients with CDI.

The Emerging Adult with Inflammatory Bowel Disease: Challenges and Recommendations for the Adult Gastroenterologist.

Incidence of pediatric inflammatory bowel disease (IBD) is rising. Adult gastroenterologists are seeing increasing numbers of young adults with IBD, a subpopulation with unique needs and challenges that can impair their readiness to thrive in an adult healthcare system. Most adult gastroenterologists might not have the training or resources to address these needs. "Emerging adulthood" is a useful developmental lens through which this group can be studied. With complex disease phenotype and specific concerns of medication side effects and reproductive health, compounded by challenges of geographical and social flux and lack of adequate health insurance, emerging adults with IBD (EAI) are at risk of disrupted care with lack of continuity. Lessons learned from structured healthcare transition process from pediatric to adult services can be applied towards challenges in ongoing care of this population in the adult healthcare system. This paper provides an overview of the challenges in caring for the post transition EAI from the perspective of adult gastroenterologists and offers a checklist of provider and patient skills that enable effective care. This paper discusses the system-based challenges in care provision and search for meaningful patient-oriented outcomes and presents a conceptual model of determinants of continuity of care in this unique population.

Procalcitonin levels associate with severity of Clostridium difficile infection.

OBJECTIVE: Clostridium difficile infection (CDI) is a major cause of morbidity and biomarkers that predict severity of illness are needed. Procalcitonin (PCT), a serum biomarker with specificity for bacterial infections, has been little studied in CDI. We hypothesized that PCT associated with CDI severity. DESIGN: Serum PCT levels were measured for 69 cases of CDI. Chart review was performed to evaluate the presence of severity markers and concurrent acute bacterial infection (CABI). We defined the binary variables clinical score as having fever (T >38°C), acute organ dysfunction (AOD), and/or WBC >15,000 cells/mm(3) and expanded score, which included the clinical score plus the following: ICU admission, no response to therapy, colectomy, and/or death. RESULTS: In univariate analysis log10 PCT associated with clinical score (OR 3.13, 95% CI 1.69-5.81, P<.001) and expanded score (OR 3.33, 95% CI 1.77-6.23, P<.001). In a multivariable model including the covariates log10 PCT, enzyme immunoassay for toxin A/B, ribotype 027, age, weighted Charlson-Deyo comorbidity index, CABI, and extended care facility residence, log10 PCT associated with clinical score (OR 3.09, 95% CI 1.5-6.35, P = .002) and expanded score (OR 3.06, 95% CI 1.49-6.26, P = .002). PCT >0.2 ng/mL was 81% sensitive/73% specific for a positive clinical score and had a negative predictive value of 90%. CONCLUSION: An elevated PCT level associated with the presence of CDI severity markers and CDI was unlikely to be severe with a serum PCT level below 0.2 ng/mL. The extent to which PCT changes during CDI therapy or predicts recurrent CDI remains to be quantified.

Clostridium difficile ribotype does not predict severe infection.

BACKGROUND: Studies of Clostridium difficile outbreaks suggested that certain ribotypes (eg, 027 and 078) cause more severe disease than other ribotypes. A growing number of studies challenge the validity of this hypothesis. METHODS: We conducted a cross-sectional study of C. difficile infection (CDI) to test whether ribotype predicted clinical severity when adjusted for the influence of other predictors. Toxigenic C. difficile isolates were cultured from stool samples, screened for genes encoding virulence factors by polymerase chain reaction (PCR) and ribotyped using high-throughput, fluorescent PCR ribotyping. We collected data for 15 covariates (microbiologic, epidemiologic, and laboratory variables) and determined their individual and cumulative influence on the association between C. difficile ribotype and severe disease. We then validated this influence using an independent data set. RESULTS: A total of 34 severe CDI cases were identified among 310 independent cases of disease (11.0%). Eleven covariates, including C. difficile ribotype, were significant predictors of severe CDI in unadjusted analysis. However, the association between ribotypes 027 and 078 and severe CDI was not significant after adjustment for any of the other covariates. After full adjustment, severe cases were significantly predicted only by patients' white blood cell count and albumin level. This result was supported by analysis of a validation data set containing 433 independent CDI cases (45 severe cases; 10.4%). CONCLUSIONS: Ribotype is not a significant predictor of severe CDI when adjusted for the influence of any other variables separately or in combination. White blood cell count and albumin level are the most clinically relevant predictors of severe CDI cases.
