ABSTRACT Digestive and liver diseases are a source of significant morbidity, mortality, and health-care costs for the U.S. population. An annual report of the toll of these diseases could be helpful to clinicians, policymakers, and researchers.
To describe the epidemiology of gastrointestinal and liver diseases in the United States using data from privately and publicly held databases.
We collected data from the National Center for Health Statistics, the National Ambulatory Medical Care Survey, the National Inpatient Sample, the Centers for Disease Control and Prevention, and the National Cancer Institute, as well as proprietary pharmaceutical databases to construct a report on the impact of gastrointestinal and liver diseases on the U.S. population. We compiled information on causes of death, hospitalization, clinic visits, cancer incidence, and mortality and infectious disease incidence from these databases, and extracted data specific to gastrointestinal diseases. Because of the high costs associated with medications used to treat gastrointestinal diseases, we also include in this year's report a special section on pharmacoepidemiology and pharmacoeconomics.
Colorectal cancer continues to be the leading cause of GI-related death, although the data indicate a downward trend in deaths. Abdominal pain, diarrhea, vomiting, and nausea are the most common GI symptoms precipitating a visit to the physician, and GERD is the most common GI-related diagnosis given in office visits. Chest pain not specified to be cardiac in origin is the most common cause of inpatient admission possibly related to GI disease, with cholelithiasis and pancreatitis following. Americans spend in excess of US dollars 10 billion/yr on proton pump inhibitors (PPIs), and two of the top five selling drugs in the United States are PPIs. Trends in PPI use demonstrate turbulent changes, likely reflecting both new drug entries into the field, as well as drug marketing. The number of PPI prescriptions/yr in the United States has doubled since 1999. Twenty-three drugs used for gastrointestinal diseases are among the top 200 generic drugs used in the United States.
Gastrointestinal and liver diseases are significant contributors to the morbidity, mortality, and health-care expenditures of the U.S. population.

    ABSTRACT: Background Metabolic syndrome has been associated with both gallstones and psoriasis, suggesting a potential biological linkage between gallstones and psoriasis. However, the association between gallstones and psoriasis has not yet been studied.Objectives To investigate the association between gallstones and psoriasis.Methods This was a prospective cohort study [Nurses’ Health Study II (1991-2005)]. Women aged 25-42 years who were free from psoriasis at baseline and who responded to a 2005 follow-up questionnaire regarding their diagnosis of psoriasis were included (n = 89 230). The relative risk (RR) of developing psoriasis or psoriatic arthritis (PsA), which were self-reported and validated by supplemental questionnaires, was measured.ResultsIn this population, 2206 participants had gallstones confirmed by a history of cholecystectomy at baseline. A total of 642 individuals had a diagnosis of incident psoriasis, of whom 157 had concomitant PsA. After adjusting for known risk factors of psoriasis besides body mass index (BMI), a baseline history of cholecystectomy-confirmed gallstones was associated with increased risk of psoriasis [multivariate-adjusted RR 2·20, 95% confidence interval (CI) 1·56-3·10] and concomitant PsA (multivariate-adjusted RR 4·41, 95% CI 2·70-7·18). After additionally adjusting for BMI, the fully adjusted RRs associated with a history of cholecystectomy-confirmed gallstones were 1·70 (95% CI 1·20-2·41) for psoriasis and 2·96 (95% CI 1·80-4·89) for PsA.Conclusions Personal history of gallstones was associated with an increased risk of psoriasis and PsA, independent of obesity, in a cohort of U.S. women.

    ABSTRACT: Data on the burden of gastrointestinal diseases are incomplete, particularly in Southern European countries. The aim of this study was to estimate the burden of digestive diseases in Portugal. This was a retrospective observational study based on the national hospitalizations database that identified all consecutive episodes with a first diagnosis of a digestive disease between 2000 and 2010 using ICD-9-CM codes. Comparative analyses were carried out to assess hospitalization trends of major indicators over time and across regions. More than 75 000 deaths attributable to digestive diseases were observed, representing 16% of the overall in-hospital mortality. Over half of these (59%) were premature deaths (in patients <75 years of age). Biliary tract disease was the most common digestive disorder leading to hospitalization (249 817 episodes, 5210 episodes of acute stone-related cholecystitis in 2010, with an 11% increase compared with 2000). Gastric cancer was responsible for the highest number of in-hospital deaths (10 278) and alcohol-related liver disorders accounted for the highest in-hospital premature deaths (7572). Both costs and the in-hospital mortality rate for major digestive diseases showed a significant positive relation with progression of time (β=0.195, P<0.001); however, when adjusted for age, this was not significant. Significant positive associations were found between age and in-hospital mortality (odds ratio=1.032, P<0.001) and between costs and in-hospital mortality (odds ratio=1.054, P<0.001). In Portugal, digestive diseases represent a major burden, with evidence of an increasing trend. An ageing population contributes strongly towards this increase, placing further demands on healthcare organizations. Diseases such as gastric cancer, biliary tract disease and alcohol-related liver disorders may require particular attention.

    ABSTRACT: Gastroesophageal reflux disease affects at least 10 % of people in Western societies and produces troublesome symptoms and impairs patients’ quality of life. The effective management of GERD is imperative as the diagnosis places a significant cost burden on the United States healthcare system with annual direct cost estimates exceeding 9 billion dollars annually. While effective for many patients, 30–40 % of patients receiving medical therapy with proton pump inhibitors experience troublesome breakthrough symptoms, and recent evidence suggests that this therapy subjects patients to increased risk of complications. Given the high cost of PPI therapy, patients are showing a decrease in willingness to continue with a therapy that provides incomplete relief; however, due to inconsistent outcomes and concern for procedure-related side effects following surgery, only 1 % of the GERD population undergoes anti-reflux surgery annually. The discrepancy between the number of patients who experience suboptimal medical treatment and the number considered for anti-reflux surgery indicates a large therapeutic gap in the management of GERD. The objective of the SSAT State-of-the-Art Conference was to examine technologic advances in the diagnosis and treatment of GERD and to evaluate the ways in which we assess the outcomes of these therapies to provide optimal patient care.
