Micronutrient deficiencies in inflammatory bowel disease: an incidence analysis.

BACKGROUND: Micronutrient deficiencies associated with malnutrition in patients with inflammatory bowel disease (IBD) can lead to complications including anemia, coagulopathy, poor wound healing, and colorectal cancer. This study aimed to investigate micronutrient deficiencies (copper, vitamins A, B 9 , E, and K) in IBD patients and highlight associated symptoms to aid in the recognition of micronutrient deficiencies. METHODS: A retrospective electronic chart review was performed on adults diagnosed with Crohn's disease or ulcerative colitis hospitalized at a tertiary care center for IBD flare between January 2013 and June 2017. Patients with serum or whole blood micronutrient levels were included. Pregnant and incarcerated patients were excluded. RESULTS: A total of 611 IBD patients (440 Crohn's disease, 171 ulcerative colitis) met the inclusion criteria. Micronutrients were assessed in a subset of IBD patients (copper: 12.3%, A: 10.1%, B 9  : 95.9%, E: 10.3%, and K: 4.6%). Overall, 10.1% of patients had micronutrient deficiencies. The proportion of patients with copper, A, B 9 , E, and K deficiencies were 25.4, 53.3, 1.9, 23.7, and 29.4% for Crohn's disease and 50, 52.9, 1.2, 43.8, and 18.2% for ulcerative colitis, respectively. The most common symptoms or historical features associated with micronutrient deficiency were anemia (copper, B 9 ), muscle weakness (copper, E) thrombocytopenia, fatigue (copper, B 9 ), diarrhea (B 9 ), dry skin, hyperkeratosis, pruritus, significant weight loss, elevated C-reactive protein (A), bleeding, and osteoporosis (K). CONCLUSION: Micronutrient deficiencies are common in IBD patients, yet they are not routinely assessed. Copper, vitamins A, E, and K deficiencies are particularly underrecognized. Associated historical features should raise suspicion and prompt assessment and treatment.

Risk of Adverse Cardiovascular Outcomes in Postmenopausal Women with Inflammatory Bowel Disease.

BACKGROUND: Individuals with inflammatory bowel disease (IBD) who lack traditional cardiovascular disease (CVD) risk factors, such as young females, are observed to experience adverse CVD outcomes. Whether women with IBD have increased CVD risk after the menopause transition is unclear. METHODS: We conducted a survival analysis of Women's Health Initiative (WHI) participants and excluded those with missing IBD diagnosis, model covariate data, follow-up data, or a baseline history of the following CVD outcomes: coronary heart disease (CHD), ischemic stroke, venous thromboembolism (VTE), peripheral arterial disease (PAD). Risk of outcomes between IBD and non-IBD women was performed using Cox proportional hazard models, stratified by WHI trial and follow-up. Models were adjusted for age, socio-demographics, comorbidities (e.g., hypertension, diabetes, hypercholesterolemia, etc.), family history, and lifestyle factors (e.g., smoking, alcohol, physical activity, body mass index, etc.). RESULTS: Of 134,022 WHI participants meeting inclusion criteria, 1367 (1.0%) reported IBD at baseline. Mean baseline age was 63.4 years. After adjusting for age and other confounders, no significant difference was observed between IBD and non-IBD women for the risk of CHD (HR 0.96, 95% CI 0.73-1.24), VTE (HR 1.11, 95% CI 0.81-1.52) or PAD (HR 0.64, 95% CI 0.28-1.42). After adjusting for age, risk of ischemic stroke was significantly higher (HR 1.41, 95% CI 1.06-1.88) in IBD than non-IBD women. With further adjustment, the excess risk of ischemic stroke among IBD women was attenuated and no longer statistically significant (HR 1.31, 95% CI 0.98-1.76). CONCLUSIONS: Among postmenopausal women with IBD, risk of ischemic stroke may be higher than in non-IBD women.

Healthcare Utilization Patterns and Excessive Steroid Use in Late Adolescence Age and Young Adults With Crohn's Disease and Ulcerative Colitis.

Background and Aims: Late adolescents and young adults (AYA) with inflammatory bowel disease (IBD) are a vulnerable population as they transition to adult healthcare. We aim to provide a real-world data on their healthcare utilization patterns and medication use through a large database. Methods: We performed a retrospective cohort study from January 1, 2012, to June 30, 2020, using OneFlorida Data-Trust, an electronic health record-based data repository representing over half of the Florida population. Outcomes of interest included demographics, healthcare utilization, medications, and disease severity. Chi-square tests and logistic regression were used to compare the rates of medication use, healthcare utilization, and disease severity by age groups. Results: The number of patients who met our inclusion criteria was 10,578 with 2731 (25.8%) in the 17-25-year-old group. AYA patients had fewer ambulatory visits vs children (90% vs 95%; P value <.05). AYA patients were admitted more frequently from emergency facilities vs children (22.3% vs 10.9%; P value <.05). AYA patients received steroids more often than adults and younger patients (48.9% vs 45.3 vs 44.3% P value <.05, respectively). AYA patients received more narcotic (41.1% vs 22.3 % P value <.05) and antidepressant prescriptions (15.9% vs 9.5%; P value <.05) compared with children. With advancing age, a decrease in biologic use was noted (51% vs 40% vs 25.4% P value <.05, respectively). Conclusion: AYA patients with IBD have higher rates of hospital admissions from emergency department, fewer ambulatory health visits and they receive more steroids compared to children. Our study demonstrates the need for age-specific IBD programs for AYA patients.

All Things Gluten: A Review.

Gluten is a common dietary component with a complex protein structure. It forms incomplete products of digestion, which have the potential to mount an immune response in genetically predisposed individuals, resulting in celiac disease. It also has been linked with nonceliac gluten sensitivity and irritable bowel syndrome due to wheat allergy. A gluten-free diet is an effective treatment of these conditions; however, it can lead to micronutrient and mineral deficiencies and a macronutrient imbalance with higher sugar and lipid intake. Recent popularity has led to greater availability, but increasing cost, of commercially available gluten-free products.

College Students with Inflammatory Bowel Disease: A Qualitative Study of Challenges Associated with College Transition and Self-Care.

Introduction: The social impact of inflammatory bowel disease (IBD) on student transition to college is significant, yet poorly understood. Methods: Two 90-min focus groups (FGs) were conducted with eight student-patients with IBD. Reflective journals were used to corroborate, elaborate, or challenge emergent FG findings. Results: Six themes emerged: (1) transitioning to college, (2) interacting with physicians, (3) affecting social life, (4) managing the disease by yourself and through support, (5) coping strategies, and (6) facing disease challenges. These themes remained relevant in the reflective writings. Analysis of serial journal entries showed that students' social life and engagement in coursework was affected 66% and 54% of the time, respectively. Conclusion: Our findings offer guidance for improving students' college success, quality of care, and enhancing physician-patient interactions. Students with IBD have a disability that may not be obvious or visible. They require specific support to help them transition and succeed in college.

Small bowel stricture is associated with abnormal motility on the cine MRI sequence in patients with Crohn's disease.

PURPOSE: A multiphasic cine sequence performed during magnetic resonance enterography (MRE) has been shown to increase diagnostic accuracy of MRE demonstrating limited movement in inflamed intestine in patients with Crohn's disease (CD). Our aim was to confirm in our study population that intestinal inflammation was associated with decreased motility and determine if factors suggestive of complicated disease such as the presence of a stricture or fistula were associated with decreased motility on the MRE cine sequence. METHODS: This was a retrospective study of 59 patients (mean age 40.8 ±â€¯16.1) with Crohn's disease who had a small bowel lesion on MRE. Two gastrointestinal radiologists independently scored MRE findings using a qualitative, subjective scoring system. Univariate and multivariable ordered logistic regression models were used to evaluate the associations between cine sequence score, radiologic image findings, and clinical data. RESULTS: On univariate analysis, radiologic findings reflecting active inflammation, the presence of a stricture, and penetrating disease were associated with decreased motility. On multivariable analysis, hyper-enhancement, the presence of a comb sign, and global evidence of active inflammation remained associated with decreased motility. Of the factors suggesting complicated disease, the presence of stricture (Odds Ratio 0.40, 95% Confidence Interval 0.17-0.95, p-value 0.038) was associated with decreased motility. CONCLUSIONS: As previously shown, well-established radiologic findings of bowel inflammation were associated with decreased small bowel motility. In this study, we have added that the radiologic finding of a fixed stricture is also associated with decreased motility.

Pre-operative total parenteral nutrition improves post-operative outcomes in a subset of Crohn's disease patients undergoing major abdominal surgery.

BACKGROUND: Despite major advances in the medical management of Crohn's disease (CD), a significant proportion of patients will require surgery within 5 years of diagnosis. Malnutrition is an independent risk factor for adverse post-operative outcomes following gastrointestinal surgery. Data on the value of pre-operative total parenteral nutrition (TPN) in CD patients are mixed and there is a paucity of data in the biologic era. We aimed to define the role of pre-operative TPN in this population. METHODS: This was a retrospective cohort study conducted at a tertiary referral center. CD patients who underwent major abdominal surgery were identified. Patients receiving pre-operative TPN were compared to controls. We compared the incidence of 30-day infectious and non-infectious post-operative complications between the two groups. RESULTS: A total of 144 CD patients who underwent major abdominal surgery between March 2007 and March 2017 were included. Fifty-five patients who received pre-operative TPN were compared to 89 controls. Twenty-one (14.6%) patients developed infectious complications (18.2% in TPN group vs 12.3% in non-TPN group, P = 0.34) and 23 (15.9%) developed non-infectious complications (14.5% in TPN group vs 16.9% in non-TPN group, P = 0.71). In a multivariate analysis, controlling for differences in baseline disease severity and malnutrition between groups, patients receiving pre-operative TPN for ≥60 days had significantly lower odds of developing non-infectious complications (odds ratio 0.07, 95% confidence interval: 0.01-0.80, P = 0.03). Weight loss of >10% in the past 6 months was a significant predictor of post-operative complications. CONCLUSIONS: In a subset of malnourished CD patients, TPN is safe and allows comparable operative outcomes to controls. Pre-operative TPN for ≥60 days reduced post-operative non-infectious complications without associated increase in infectious complications.

Real-world Pattern of Biologic Use in Patients With Inflammatory Bowel Disease: Treatment Persistence, Switching, and Importance of Concurrent Immunosuppressive Therapy.

BACKGROUND AND AIMS: Medication persistence, defined as the time from drug initiation to discontinuation of therapy, has been suggested as a proxy for real-world therapeutic benefit and safety. This study seeks to compare the persistence of biologic drugs among patients with inflammatory bowel disease (IBD). METHODS: Patients with newly diagnosed IBD were included in a retrospective study using Truven MarketScan database. Treatment persistence and switching was compared among biologic medications including infliximab, adalimumab, certolizumab, golimumab, and vedolizumab. Predictors for discontinuation and switching were evaluated using time-dependent proportional hazard regression. RESULTS: In total, 5612 patients with Crohn's disease (CD) and 3533 patients with ulcerative colitis (UC) were included in this analysis. Less than half of the patients continued using their initial biologic treatment after 1 year (48.48% in CD cohort; 44.78% in UC cohort). In the first year, adalimumab had the highest persistence and lowest switching rates for both CD (median survival time: 1.04 years) and UC (median survival time: 0.84 years). In subsequent years, infliximab users were more likely to persist in the use of biologic. Combination therapy with immunomodulators significantly decreased the risk of discontinuation, especially when immunomodulator therapy was started more than 30 days before the biologic (hazard ratio [HR], 0.22; CI, 0.16, 0.32). The major predictors for noncompliance included infection and hospitalization. CONCLUSION: Overall, the persistence profiles of biologics suggest a high rate of dissatisfaction or adverse disease outcomes resulting in discontinuation and switching to a different agent. Early initiation of immunomodulators will substantially increase the persistence of biologic treatment.

Effects of Preoperative Use of Biologic Agents on Operative Outcomes in Crohn's Disease Patients.

Although the effects of biologic agents on postoperative outcomes in Crohn's disease patients have been extensively studied, the effects on intraoperative outcomes, including blood loss, operative time, and length of small bowel resection, remain to be determined. This was a retrospective cohort study at a single tertiary referral center. Crohn's disease (CD) patients who underwent major abdominal surgery were identified. Patients receiving preoperative biologic agents were compared with controls. We compare operative outcomes between groups. A total of 144 patients who underwent major abdominal surgery at the University of Florida between March 2007 and March 2017 were included. One hundred and ten patients (76%) who received preoperative biologic therapy were compared with 34 controls. On univariate analysis, preoperative biologic use was associated with a significantly shorter length of small bowel resection (21.2 cm in biologic group vs 34.5 cm, P = 0.01). There were no significant differences in intraoperative blood loss (100 vs 87.5 mL, P = 0.40) or total operative time (142 vs 154 minutes, P = 0.39) between groups. On multivariate analysis controlling for variables reflecting severity of disease and malnutrition, biologic use remained significantly associated with shorter length of bowel resection (incident rate ratio 0.58, P = 0.04). Preoperative biologic use is associated with a significantly shorter length of bowel resection in CD patients undergoing major abdominal surgery. No negative effects were noted on operative blood loss or total operative time. Our findings allow improved preoperative planning for surgeons and informed decision-making for CD patients undergoing major abdominal surgery.

Effective communication of cross-sectional imaging findings in Crohn's disease: comparing conventional EMR reporting to a published scoring system.

PURPOSE: The purpose of the article is to compare information regarding small bowel lesions in Crohn's disease (CD) patients communicated by a published scoring system and radiology reports from electronic medical record (EMR) of cross-sectional abdominal imaging. METHODS: Two gastrointestinal radiologists (reference readers) blinded to EMR reports scored cross-sectional imaging exams using a published scoring system. Investigators compared EMR and radiologist scores based on the mentioned findings and severity documentation of each variable. Statistical analysis involved means and difference in proportions and logistic regression modeling. RESULTS: Seventy-three CD patients, with average age 40.6 years (± SD 14.4), having 80 small bowel lesions on imaging were included. EMR reports reliably mentioned within the consensus score included thickness (79%, p = 0.000), enhancement (70%, p = 0.000), active inflammation (86%, p = 0.000), perienteric fluid (82%, p = 0.000), and presence of stricture (62%, p = 0.002). Minimal lumen diameter (19%, p = 0.000), comb sign (19%, p = 0.000), lesion length (57%, p = 0.06), and fistula (50%, p = 1.0) were reported less often. There was a strong association between the EMR and scoring scale in noting severity of active inflammation (88%, p = 0.000), perienteric fluid (76%, p = 0.000), and internal fistula (71%, p = 0.000). The proportion matching severity values of comb sign and minimal lumen were 24% and 21%, respectively (p = 0.000). Severity matches for stricture were less likely among the non-GI radiologists (odds ratio = 0.33, SE = 0.168, p = 0.029). The odds of reporting stricture and fistula severity were 3.6 and 5.7, respectively, on MRE. CONCLUSIONS: Findings and severity of inflammation were communicated consistently. Stricture severity including minimal luminal diameter, was less reliably reported, though its prognostic significance impacts management.

Transmitted cardiovascular pulsations on high resolution esophageal impedance manometry, and their significance in dysphagia.

AIM: To investigate the behavior of pulsatile pressure zones (PPZ's) as noted on high resolution esophageal impedance manometry (HREIM), and determine their association with dysphagia. METHODS: Retrospective, single center case control design screening HREIM studies for cases (dysphagia) and controls (no dysphagia). Thoracic radiology studies were reviewed further in cases for (thoracic cardiovascular) thoracic cardiovascular (TCV) structures in esophageal proximity to compare with HREIM findings. Manometric data was collected for number, location, axial length, PPZ pressure and esophageal clearance function (impedance). RESULTS: Among 317 screened patients, 56% cases and 64% controls had PPZ's. Fifty cases had an available thoracic radiology comparison. The distribution of PPZ's in these 50 cases and 59 controls was similar (average 1.4 PPZ/patient). Controls (mean 31.2 ± SD 12 years) were a significantly younger population than cases (mean 67.3 ± SD 14.9 years) with P < 0.0001. The upright posture PPZ pressure was higher in controls (15.7 ± 10.0 mmHg) than cases (10.8 ± 9.7 mmHg). Although statistically significant (P = 0.005), it was a weak predictor using logistic regression and ROC model (AUC = 0.65). Three dysphagia patients had partial compression from external TCV on radiology (1 aberrant subclavian artery, 2 dilated left atrium). The posture (supine vs upright) with more prominent PPZ's impaired bolus clearance in 9 additional cases by > 20%. CONCLUSION: Transmitted TCV pulsations observed in HREIM bear no significant impact on swallowing. However, in older adults with dysphagia, evidence of impaired bolus clearance on impedance should be evaluated for external TCV compression. These associations have never been explored previously in literature, and are novel.

A Fixed Stricture on Routine Cross-sectional Imaging Predicts Disease-Related Complications and Adverse Outcomes in Patients with Crohn's Disease.

BACKGROUND: Patients with Crohn's disease (CD) typically undergo multiple cross-sectional imaging exams including computed tomography and magnetic resonance enterography during the course of their disease. The aim was to identify imaging findings that predict future disease-related poor outcomes. METHODS: This was a retrospective, case control study at a single tertiary center. Cases were CD patients diagnosed with complications (bowel obstruction, perforation, internal fistula, or abscess); controls were CD patients without complications. Two radiologists blinded to clinical outcomes, independently scored cross-sectional imaging examinations obtained before the complication. RESULTS: One hundred eight patients (67 F; 41 M) with CD (51 cases; 57 controls) were included. For the cases, 21 had internal fistulae, 15 had bowel obstructions, 13 had abdominal abscesses, and 2 developed bowel perforations. Patients with complications were more likely to have a fixed small bowel stricture on cross-sectional imaging (P = 0.01). A patient with a stricture and upstream dilatation was 3.4 times more likely to develop a complication in the next 2 years. When present in the setting of hypervascularity and/or evidence of active inflammation, the risk increased further to 15-fold. Cases were more likely to be active smokers (29% versus 12%, P = 0.033). Cases had more evidence of inflammation based on higher Harvey Bradshaw Index values and inflammatory biomarkers and lower hemoglobin values. CONCLUSIONS: Information from radiologic studies, especially the presence of fixed strictures, can predict future CD complications. These findings, along with smoking and ongoing inflammation, should alert the clinician to the possibility of future complications.

Jackhammer oesophagus in a case of linitis plastica.

A 52-year-old Caucasian woman presented with progressive nausea and vomiting, weight loss, and burning epigastric and chest pain. Initial oesophagogastroduodenoscopy (OGD) with biopsies demonstrated gastritis in absence of Helicobacter pylori A gastric emptying study, CT scan with pancreatic protocol and a colonoscopy revealed no concerning findings. Calcium channel blockers and proton pump inhibitors offered little improvement. A high-resolution oesophageal impedance manometry was performed, which was significant for jackhammer oesophagus with maximum distal contractile index 11 052 mm Hg-s-cm. Another OGD was carried out for Botox injection to oesophagogastric junction. Repeat gastric biopsies reported gastric adenocarcinoma, further diagnosed as stage 4 linitis plastica with metastatic peritoneal carcinomatosis. To the best of our knowledge, this is the only case of linitis plastica associated with jackhammer oesophagus.

To Study the Clinical, Biochemical and Radiological Features of Acute Pancreatitis in HIV and AIDS.

BACKGROUND: Pancreatitis complicating HIV infection, even in the Highly Active Antiretroviral Therapy (HAART) era, remains a management challenge. We felt there is a need to discern patterns in the biochemical markers, radiological studies, co-infections, length of stay (LOS) in patients with HIV or AIDS AND pancreatitis. METHODS: This is a retrospective study conducted from June, 2008 to August, 2010 on patients admitted with acute pancreatitis to our hospital. We extracted and compared the following parameters: biochemical markers, HBV markers (surface antigen, core antibody and surface antibody), HCV antibody, radiological studies, and length of stay (LOS). The Balthazar Grade score was used to assess radiological severity of disease. We stratified the cohort into comparison subsets according to CD4 count. RESULTS: Ninety-four admissions met the criteria for HIV or AIDS AND pancreatitis; 67 unique patients comprised the cohort. Median age was 48 years (range, 23 to 60 years). Thirty seven (55%) were male, 30 (45%), female. Two third (n = 51) (76%) were African American. Known risk factors included a history of pancreatitis, 17 (25%); cholecystitis, 13 (19%); alcohol abuse, 25 (37%); Intravenous drug abuse, 18 (27%). Only 36 (38%) admissions were on HAART regimen. Biochemical features on admission were: WBC, 6,100/mm(3) (900 - 25,700); amylase, 152 U/L (30 - 1,344); lipase, 702.5 U/L (30 - 5,766), triglyceride, 65 mg/dL (57 - 400); glucose, 94 mg/dL (60 - 1,670); lactate, 2.3 mmol/L (1.09 - 5.49); AST, 61.5 U/L (9 - 1,950); LDH, 762 U/L (394 - 5,500); bicarbonate 19.5 mEq/L (3.3 - 82.7). Interestingly, 62% patients had normal pancreas on CT scan on admission. Of 67 individuals, hepatitis profile was available in 43, 21 (49%) were positive for HCV, 11 (26%) had markers for HBV. Four of 11 patients (36) with CD4 < 50 had evidence of persistent HBV (+core, -surface ab). Patients with CD4 < 200 have a median time for hospital course of 8 days (range 4 - 61 days) compare to 3 days in patients with CD4 > 200. P = 0.03 via t-test comparison. One patient with CD4 < 50 died due to acute pancreatitis. CONCLUSION: Pancreatitis remains a major cause of morbidity in HIV-infected individuals. This study has provided detailed features in the HAART therapy era about the clinical, biochemical and radiological features of pancreatitis. Half of our patients were positive for HCV; additionally, 36% with CD4 < 50 had persistent HBV. As opposed to earlier studies, we did not find a female predominance. Patients with CD4 < 200 had a 2.67-fold increase length of stay. Future studies are needed for a closer look on viral cofactors which might precipitate episodes of acute pancreatitis.
