Celiac Disease Presenting in a Community-Based Gastroenterology Practice: Obesity and Bone Disease Are Common.

BACKGROUND: The description of the clinical presentation of celiac disease (CeD) has usually come from studies at referral centers. Data about CeD presentation in the community are sparse. AIMS: We aim to describe the clinical presentation of patients with biopsy-proven CeD at a community-based adult gastroenterology practice and compare it to a referral center. METHODS: We performed a retrospective study of two cohorts of patients diagnosed with CeD between 2000-2007 (n = 117) and 2013-2016 (n = 91) in a community practice, and a third cohort (n = 188) diagnosed between 2000 and 2007 in a tertiary referral center. The clinical presentation, body mass index, tissue-transglutaminase levels, DEXA scan, vitamin D levels, and vaccine recommendations were assessed. RESULTS: Celiac disease presentation changed over time in the two community cohorts. Recently, fewer patients presented with diarrhea and anemia, but constipation and neurologic symptoms were more common. The most recent cohort had a higher proportion of patients who were overweight or obese than the first cohort. However, the body mass index in both community cohorts was higher than in the tertiary referral center. The frequency of osteopenia and osteoporosis was high in both community cohorts. The tertiary referral center patients were younger, presented with a higher proportion of diarrhea and a lower body mass index. CONCLUSIONS: The clinical presentation of CeD differs between the community setting and a tertiary referral center. Patients with CeD presenting to the community setting tended to be older, overweight, and to have a high proportion of mineral bone disease.

Whipple's Disease Mimicking Common Digestive Disorders.

Whipple's disease is a rare infectious disease caused by the bacterium Tropheryma whipplei. The prevalence of Whipple's disease is 3/1,000,000 in Western populations. It most often causes a malabsorption disorder with weight loss and diarrhea as common presenting symptoms. In one-third of patients, however, there are no gastrointestinal symptoms at presentation; patients instead report a wide variety of non-specific extraintestinal complaints, potentially involving every organ system. We report a case of a 37-year-old man who presented with a 3-month history of non-bloody diarrhea and 15-pound weight loss. He was ultimately diagnosed with biopsy-confirmed Whipple's disease. Despite its rarity, Whipple's disease remains an important clinical entity and should be included on the differential diagnosis for selected patients presenting with an array of non-specific symptoms.

The Role of Clinical Characteristics in Stratifying Sedation Risk: A Cohort Study.

BACKGROUND: Determination of sedation type during gastrointestinal procedures is generally based on risk assessment via the American Society of Anesthesiologists (ASA) classification system, but the reliance of anesthesia risk on clinical factors remains largely uninvestigated. We aim to determine the association between various clinical factors and choice of sedation type during gastrointestinal procedures. METHODS: This single-center, retrospective cohort study used electronic medical records to identify patients receiving colonoscopy or endoscopy at Rhode Island Hospital. The electronic medical record was queried for history of alcohol abuse, opioid abuse, polysubstance abuse, prescriptions for psychotropic or opioid medications and ASA classification. Logistic regression was used to measure how patient characteristics correlated with sedation type. RESULTS: Totally, 2,033 patients were included in the study; 1,080 patients received moderate sedation and 853 received monitored anesthesia care (MAC). Three hundred fifty-four (60.2%) MAC patients had a history of alcohol abuse compared to 234 (39.8%) moderate sedation patients (P < 0.2334); 178 (62.9%) MAC and 105 (37.1%) moderate sedation patients had a history of opioid abuse (P < 0.001); 203 (73.6%) MAC and 73 (26.4%) moderate sedation patients had a history of polysubstance abuse (P < 0.001); and 815 (75.1%) MAC patients had psychiatric comorbidities versus 270 (24.9%) in the moderate sedation group (P < 0.001). In the MAC cohort, alcohol, opioid, polysubstance abuse and psychiatric history were associated with previous failure of moderate sedation (P < 0.0001). CONCLUSIONS: For a subset of patients, clinical factors including alcohol, opioid, polysubstance abuse and psychiatric history, in addition to ASA classification, play an important role in sedation management.

Solitary fibrous tumor of the pancreas clinically mimicking a pancreatic neuroendocrine tumor: Cytologic pitfalls when a transgastric approach is utilized.

Solitary fibrous tumor (SFT) involving the pancreas is a rare entity often diagnosed on surgical specimens rather than cytology samples. Pancreatic SFT frequently mimics pancreatic neuroendocrine tumor radiographically, which presents unique challenges to the cytologist during rapid on-site assessment. We describe a case of pancreatic SFT with a focus on the cytologic pitfalls that might be encountered during transgastric procedures. We also review the available cytologic findings of prior pancreatic SFT cases.

Pneumatosis Coli Formation via Counterperfusion Supersaturation in a Patient with Severe Diarrhea.

We present the case of an elderly male patient with known multiple myeloma who was hospitalized with profuse watery diarrhea and abdominal pain after a course of induction chemotherapy. Intestinal intramural gas was found on imaging and the diagnosis of pneumatosis intestinalis was confirmed by colonoscopy. We propose counterperfusion supersaturation as the etiology for this patient's pneumatosis coli via disruption of homeostasis between nitrogen and hydrogen normally present in the bowel. His condition was successfully treated with antidiarrheal medications and inhaled oxygen as well as intravenous hydration, and he eventually completed multiple myeloma directed chemotherapy with an excellent response. In this report, we discuss how clinicians can improve management of pneumatosis intestinalis by understanding the proposed pathophysiology.

Factors Associated with the Use of Fecal Microbiota Transplant in Patients with Recurrent Clostridium difficile Infections.

OBJECTIVE To identify the factors associated with first Clostridium difficile infection (CDI) that predict fecal microbiota transplantation (FMT) for recurrent CDI DESIGN We carried out a retrospective single-center cohort study to compare the clinical characteristics of 200 patients who underwent FMT for recurrent CDI to 75 patients who did not. SETTING A single academic hospital in the United States PATIENTS Adult patients RESULTS The time from first to second CDI correlated to subsequent FMT use. Concomitant inflammatory bowel disease (IBD; P=.002), use of immunosuppressive therapy (P=.04), and use of metronidazole within 2 months before the first CDI (P=.02) correlated positively to subsequent FMT in univariate analysis. The use of oral vancomycin for first CDI was more common in those who required FMT than those who did not in univariate (P=.02) and multivariate (P=.03) analyses. In contrast, intravenous vancomycin use within 2 months before the first CDI reduced the risk for FMT in univariate P=.000003) and multivariate (P=.0001) analyses. Black patients with recurrent CDI were less likely to receive FMT than white patients (P=.00005). Patients who received FMT were also less likely to have comorbidities. CONCLUSIONS This study provides important insights into the factors predictive for FMT in patients with recurrent CDI and highlights the potential racial and medical characteristics that affect the access of the patients to FMT.
