Maternal, obstetrical, and neonatal outcomes in celiac disease

OBJECTIVES

Some studies have suggested a link between celiac disease (CD) and adverse maternal, obstetrical, and neonatal outcomes. Using a large database, we evaluated the effect of CD on pregnancy outcomes.

METHODS

We conducted a retrospective cohort study using the National Inpatient Sample (NIS) of all deliveries from 2015 to 2019 in the United States. Using ICD-10 codes, we identified pregnant patients who had CD and those who did not. A multivariate logistic regression was used to generate odds ratios (ORs) with 95% confidence intervals (CIs) for maternal, obstetrical, and neonatal outcomes.

RESULTS

Of 12,039,222 deliveries between 2015 and 2019, there were 10,555 births in women with CD. Pregnant women with CD were more likely to be white and older compared to those without CD. Pregnant women with CD were significantly more likely to carry a diagnosis of gestational hypertension (OR 1.26; 95% CI 1.04-1.52), preeclampsia (1.28; 1.08-1.53), and severe preeclampsia (1.62; 1.25-2.09). They were less likely to have a full-term uncomplicated delivery (OR 0.11; 95% CI, 0.05-0.20), while being more likely to require device-assisted delivery (1.25; 1.04-1.50) and sustain 3rd or 4th degree vaginal lacerations (1.56; 1.21-2.02). Babies of pregnant women with CD were more likely to be small for gestational age (SGA) (OR 1.29; 95% CI 1.03-1.61).

CONCLUSIONS

CD in pregnancy appears to be associated with increased adverse maternal, obstetrical, and neonatal outcomes. Clinicians should discuss these increased risks with CD patients who are planning to conceive.

Epidemiology of neuroendocrine tumors of the appendix in the USA: a population-based national study (2014-2019)

Background

The appendix is the third most common place for neuroendocrine tumors (NETs) along the digestive tract and NETs are the most common neoplasms of the appendix. However, there are limited population-based data on the epidemiology of this disease. Using a large database, we sought to describe the epidemiology and risk association of NETs of the appendix.

Method

We queried a multi-institutional database (Explorys Inc., Cleveland, OH, USA), comprising 360 hospitals in the United States (US), for patients with a diagnosis of NETs of the appendix from 2014-2019.

Results

Of the 30,324,050 individuals in the database, 2020 patients had an appendiceal NET diagnosis (0.007%). The most common presenting symptoms included abdominal pain, nausea, vomiting and diarrhea. Patients with appendiceal NETs were more likely to be female (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.24-1.49), Caucasian (OR 2.71, 95%CI 2.40-3.07), with a history of smoking (OR 1.82, 95%CI 1.65-2.01), family history of primary gastrointestinal malignancy (OR 7.26, 95%CI 6.31-8.33), diagnosis of multiple endocrine tumor type 1 (OR 52.31, 95%CI 23.15-118.23), or neurofibromatosis type 1 (OR 16.37, 95%CI 7.24-37.01).

Conclusions

In a population-based study in the US, using the Explorys database, we found the overall prevalence of NETs of the appendix to be 7 per 100,000 persons. The incidence in the year January 2019-January 2020 was 0.4 per 100,000 individuals. These rates are higher than previously reported and may be more accurate, given the more comprehensive nature of the Explorys database.

The Risk of Acute and Chronic Pancreatitis in Celiac Disease

BACKGROUND AND AIMS

Celiac disease (CD) is a chronic immune-mediated enteropathy that is precipitated by dietary gluten in genetically predisposed individuals. A few studies reported a higher incidence of pancreatitis in the CD population. Using a large US database, we sought to describe the epidemiology, risk, and outcomes of acute pancreatitis (AP) and chronic pancreatitis (CP) in CD patients.

METHODS

We queried a multiple health system data analytics and research platform (Explorys Inc, Cleveland, OH, USA). A cohort of patients with a diagnosis of CD was identified. Subsequently, individuals who developed a new diagnosis of AP and CP after at least 30 days of being diagnosed with CD were identified. A multivariate regression model was performed to adjust for multiple confounding factors.

RESULTS

Of the 72,965,940 individuals in the database, 133,400 (0.18%), 362,050 (0.50%), and 95,190 (0.13%) had CD, AP, and CP, respectively. New diagnosis of AP and CP after at least 30 days of CD diagnosis was 1.06%, 0.52%, respectively, compared to non-CD patients with 0.49% for AP and 0.13% for CP, P < .0001. In multivariate regression analysis, patients with CD were at higher risk of developing AP [OR 2.66; 95% CI 2.55-2.77] and CP [OR 2.18; 95% CI 2.04-2.34]. Idiopathic AP was the most common etiology among CD patients [OR 1.54; 95% CI 1.34-1.77].

CONCLUSIONS

In this largest US population database and after adjusting for several confounders, patients with CD were at increased risk of developing AP and CP. Celiac disease patients had worse outcomes and higher medical burden compared to non-CD patients. Recurrent abdominal pain that suggests pancreatic etiology, idiopathic pancreatitis, or elevation of pancreatic enzymes should warrant investigation for CD as a potential cause of pancreatic disease.

Epidemiology and risk of psychiatric disorders among patients with celiac disease: A population-based national study

BACKGROUND AND AIM

Celiac disease (CD) is a chronic disorder resulting from an immune reaction to gluten in genetically predisposed individuals. Although several studies have linked CD to psychiatric diseases, there are limited data on this topic. Using a large database, we sought to describe the epidemiology of several psychiatric disorders in CD.

METHODS

We queried a multicenter database (Explorys Inc), an aggregate of electronic health record data from 26 major integrated healthcare systems from 2016 to 2020 consisting of 360 hospitals in the USA. A cohort of patients with a Systematized Nomenclature Of Medicine - Clinical Terms diagnosis of CD was identified. Multivariate analysis was performed using Statistical Package for Social Sciences version 25.

RESULTS

Of the 37 465 810 patients in the database between 2016 and 2020, there were 112 340 (0.30%) individuals with CD. When compared with patients with no history of CD, patients with CD were more likely to have a history of anxiety (odds ratio [OR]: 1.385; 95% confidence interval [CI]: 1.364-1.407), depression (OR: 1.918; 95% CI: 1.888-1.947), bipolar (OR: 1.321; 95% CI: 1.289-1.354), attention-deficit hyperactivity disorder (OR: 1.753; 95% CI: 1.714-1.792), eating disorder (OR: 15.84; 95% CI: 15.533-16.154), and childhood autistic disorder (OR: 4.858; 95% CI: 3.626-6.508). Patients with CD and psychiatric conditions were more likely to be smokers, with history of alcohol and substance abuse as well as a history of personality disorder.

CONCLUSIONS

In this large database, patients with CD are at increased risk of having multiple psychiatric diseases including anxiety, depression, bipolar, attention-deficit hyperactivity disorder, eating disorder, and childhood autism. Individual care and referral to psychiatry when appropriate are warranted while taking care of this group of patients.

Implications of artificial intelligence in inflammatory bowel disease: Diagnosis, prognosis and treatment follow up

Driven by the tremendous availability of data, artificial intelligence (AI) using deep learning has emerged as a breakthrough computer technology in the last few decades and has recently been acknowledged by the Task Force on AI as a golden opportunity for research. With its ability to understand, learn from and build on non-linear relationships, AI aims to individualize medical care in an attempt to save time, cost, effort and improve patient’s safety. AI has been applied in multiple medical fields with substantial progress made in gastroenterology mainly to facilitate accurate detection of pathology in different disease processes, among which inflammatory bowel disease (IBD) seems to drag significant attention, specifically by interpreting imaging studies, endoscopic images and videos and -to a lesser extent- disease genomics. Moreover, models have been built to predict IBD occurrence, flare ups, persistence of histological inflammation, disease-related structural abnormalities as well as disease remission. In this article, we will review the applications of AI in IBD in the present medical literature at multiple points of IBD timeline, starting from disease prediction via genomic assessment, diagnostic phase via interpretation of radiological studies and AI-assisted endoscopy, and the role of AI in the evaluation of therapy response and prognosis of IBD patients.

Epidemiology of gallbladder cancer in the Unites States: a population-based study

BACKGROUND

Gallbladder cancer (GBC) is the most common neoplasm of the biliary tract with the lowest rates of survival. Most GBCs are adenocarcinomas that arise from the epithelial lining of the gallbladder. There are limited data in the literature regarding the epidemiology of GBC. Using a large database, we aim to describe the epidemiology using a US population database.

METHODS

A multi-institutional database (Explorys Inc., Cleveland, OH, USA) was surveyed. A cohort of patients with a primary malignant neoplasm of gallbladder between 1999-2019 was identified. The prevalence rate was calculated and age-, race-, and sex-based distributions were described. Multivariate analysis was done to evaluate underlying associations.

RESULTS

Of the 56,197,690 individuals in the database, 4,790 individuals with GBC were identified with a prevalence rate of 8.5 per 100,000. Asian race has the highest prevalence of GBC (13.6/100,000). Patients with GBC were also more likely to be smokers, have a history of alcohol abuse, obesity, diabetes, cholelithiasis, chronic cholecystitis, primary sclerosing cholangitis (PSC), and chronic viral hepatitis.

CONCLUSIONS

This is one of the largest US population studies to date evaluating the epidemiology of GBC. The 20-year period prevalence rate of GBC was 8.5 per 100,000. Patients with GBC were more likely to be elderly, females, obese, diabetic, and have chronic hepatobiliary disorders.

Increasing Prevalence of Anxiety and Depression Disorders After Diagnosis of Chronic Pancreatitis: A 5-Year Population-Based Study

OBJECTIVES

Chronic pancreatitis (CP) is often associated with poor quality of life. Only a few small associative studies have reported the prevalence of mood disorders in CP. Using a large database, we sought to describe the epidemiology and risk association of anxiety and depression in CP and evaluate their outcomes.

METHODS

A multicenter database (Explorys), an aggregate of electronic health record data from 26 US healthcare systems, was surveyed. A cohort of patients with a diagnosis of CP between 2014 and 2019 was identified. Within this cohort, rates of anxiety and depression were calculated. Demographics, comorbidities, and outcomes were described.

RESULTS

Of the 30,276,810 individuals in the database (2014-2019), 67,260 patients had a CP diagnosis (0.22%). When compared with patients with no history of CP, patients with CP were more likely to develop anxiety (odds ratio, 6.94; 95% confidence interval, 6.85-7.04) and depression (odds ratio, 5.09; 95% confidence interval, 5.01-5.17). Chronic pancreatitis patients with depression had an increased risk of suicidal ideation compared with controls.

CONCLUSIONS

Patients with CP are at a higher risk of developing anxiety and depression compared with those without CP, with overall worse outcomes. Clinicians should screen CP patients and make appropriate referral to psychiatry when indicated.

Pyloroplasty and the risk of Barrett's esophagus in patients with gastroparesis

Barrett's esophagus (BE), a consequence of gastroesophageal reflux disease (GERD), is a premalignant condition for esophageal adenocarcinoma. Impaired gastric emptying leads to increased gastric volume and therefore more severe reflux. We seek to investigate the association between gastroparesis and BE and the predictors of BE among patients with gastroparesis. This is a retrospective review of patients seen at Cleveland Clinic between 2011 and 2016 who had an upper endoscopy and a gastric emptying study. Demographics, symptoms, medications, endoscopic and histological findings, and therapeutic interventions were abstracted. Risk of BE among gastroparesis group and control group was assessed, and logistic regression analysis was performed to identify predictors of BE among gastroparesis patients. Of the 4,154 patients, 864 (20.8%) had gastroparesis and 3, 290 (79.2%) had normal gastric emptying. The mean age was 51.4 ± 16.4 years, 72% were women and 80% were Caucasians. Among the gastroparesis group, 18 (2.1%) patients had BE compared to 71 (2.2%) cases of BE in the control group, P = 0.89. There were no differences in gender, race, reflux symptoms, or esophageal findings between the two groups. Among gastroparesis group, predictors of developing BE were a history of alcohol use (odds ratio [OR] 6.76; 95% confidence intervals [CI]: 1.65-27.67, P = 0.008), history of pyloroplasty (OR: 8.228; CI: 2.114-32.016, P = 0.002), and hiatal hernia (OR: 8.014; CI: 2.053-31.277, P = 0.003). Though gastroparesis is a known contributing factor for GERD, there was no increased prevalence of BE in gastroparesis. Among patients with gastroparesis, predictors of BE are history of alcohol use, hiatal hernia, and pyloroplasty.
