BACKGROUND: With over 110,000 bariatric operations performed in the United States annually, it is important to understand the biochemical abnormalities causing endocrine dysfunction associated with these procedures. Here we compare 2 malabsorptive procedures, duodenal switch and Roux-en-Y gastric bypass, to determine the role malabsorption plays in secondary hyperparathyroidism in this population. METHODS: Data from all super-obese patients undergoing duodenal switch or Roux-en-Y gastric bypass between August 2002 and October 2005 were prospectively collected...

Intestinal failure (IF) is a state in which the nutritional demands of the body are not met by the gastrointestinal absorptive surface. It is a long-recognized complication associated with short bowel syndrome, which results in malabsorption after significant resection of the intestine for many reasons or functional dysmotility. Etiologies have included Crohn's disease, vascular complications, and the effects of radiation enteritis, as well as the effects of intestinal obstruction, dysmotility, or congenital defects...

Cystic fibrosis (CF) is a serious autosomal recessive genetic disorder associated with chronic lung disease, malabsorption, malnutrition, pancreatic insufficiency and premature respiratory failure. Recent advances in medical science and technology have increased the lifespan of patients with CF, albeit with long-term consequences of the disease, such as osteoporosis, becoming of increasing significance. The medical treatment of osteoporosis in patients with CF or after organ transplantation is still being explored, and no clear guidelines regarding the best choice of bisphosphonate exist...

BACKGROUND: Refeeding syndrome (RFS) is an important and well-known complication in malnourished patients, but the incidence of RFS after obesity surgery is unknown and the awareness of RFS in obese patients as a postsurgical complication must be raised. We present a case of RFS subsequent to biliopancreatic diversion in a morbidly obese patient. CASE REPORT: A 48-year-old female patient with a BMI of 41.5 kg/m2 was transferred to our hospital due to Wernicke's Encephalopathy in a global malabsorptive syndrome after biliopancreatic diversion...

BACKGROUND: Up to 90% of people with scleroderma have gastrointestinal (GI) problems such as constipation, bloating, diarrhea, and malabsorption. These problems significantly impair quality of life. Our objective was to determine the risk factors for gastrointestinal issues in people with scleroderma. METHODS: We conducted a systematic review of observational studies that report GI problems in patients with scleroderma along with the associated risk factors. We were interested in any GI problem and any risk factor as long as the study included patients diagnosed with scleroderma according to the 1980 or 2013 American College of Rheumatology guideline...

The 25-hydroxyvitamin D (25OHD) serum concentration should not be measured to everybody but recommendations for this measurement in several clinical situations are available from numerous guidelines and expert positions. It can be proposed to measure 25OHD in diseases where a target range of 25OHD concentrations associated with better outcomes is defined with a sufficient level of evidence, and when this target concentration is difficult to reach without previous measurement (or may be exceeded in case of too large doses are provided)...

An old saying states that ''children are not little adults" and this certainly holds true for celiac disease, as there are many peculiar aspects regarding its epidemiology, diagnosis, clinical presentations, associated diseases, and response to treatment in pediatric compared to adult populations, to such an extent that it merits a description of its own. In fact, contrary to the past when it was thought that celiac disease was a disorder predominantly affecting childhood and characterized by a malabsorption syndrome, nowadays it is well recognized that it affects also adult and elderly people with an impressive variability of clinical presentation...

Inflammation can lead to malabsorption of important micronutrients such as iron. Malabsorption and nutritional deficiency can be caused by a variety of pathological and environmental factors causing a range of other symptoms commonly caused by both H. pylori infection and coeliac disease (CD). National guidelines suggest the routine taking of duodenal biopsies to exclude CD when investigating patients for iron deficiency anemia (IDA). Studies suggest that in absence of positive antibodies, IDA is rarely caused by CD...

BACKGROUND: Measurement of vitamin A (retinol) and E (alpha-tocopherol) in UK clinical laboratories is currently performed exclusively by high-performance liquid chromatography with ultraviolet detection. We investigated whether retinol and alpha-tocopherol could be measured simultaneously by liquid chromatography tandem mass spectrometry. METHODS: Serum samples (100 μL) were extracted using Isolute + Supported Liquid Extraction plates. Chromatography was performed on a Phenomenex Kinetex Biphenyl 2...

Although recognised as a cause of chronic diarrhoea for over forty years, diagnostic tests and treatments for bile acid malabsorption (BAM) remain controversial. Recent National Institute for Health and Care Excellence (NICE) guidelines highlighted the lack of evidence in the field, and called for further research. This retrospective study explores the BAM subtype and severity, the use and response to bile acid sequestrants (BAS) and the prevalence of abnormal colonic histology. 264 selenium-75-labelled homocholic acid conjugated taurine (SeHCAT)-tested patient records were reviewed and the severity and subtype of BAM, presence of colonic histopathology and response to BAS were recorded...

A small subset of celiac disease (CD) patients becomes refractory to a gluten-free diet with persistent malabsorption and intestinal villous atrophy. This is a rare (probably less than 2% of adult CD patients), but serious disorder, with a high risk of progression to an overt T-cell lymphoma. Diagnosis of this condition defined as refractory CD (RCD) is made after exclusion of other small bowel diseases with villous atrophy. RCD has been subdivided into two subgroups according to the normal (RCDI) or abnormal phenotype of intraepithelial lymphocytes (RCDII)...

BACKGROUND: Irritable bowel syndrome is a widespread disorder with a marked socioeconomic burden. Previous studies support the proposal that a subset of patients with features compatible with diarrhoea-predominant IBS (IBS-D) have bile acid malabsorption (BAM). AIM: To perform a systematic review and meta-analysis to assess the prevalence of BAM in patients meeting the accepted criteria for IBS-D. METHODS: MEDLINE and EMBASE were searched up to March 2015...

This national clinical guideline approved by the Danish Society for Gastroenterology and Hepatology describes the diagnosis and treatment of celiac disease (CD) in adults. CD is a chronic immune-mediated enteropathy of the small intestine triggered by the ingestion of gluten-containing proteins, which are found in wheat, rye, and barley. The disease prevalence is 0.5-1.0%, but CD remains under-diagnosed. The diagnosis relies on the demonstration of lymphocyte infiltration, crypt hyperplasia, and villous atrophy in duodenal biopsies...

A general overview is given of the causes of anemia with iron deficiency as well as the pathogenesis of anemia and the para-clinical diagnosis of anemia. Anemia with iron deficiency but without overt GI bleeding is associated with a risk of malignant disease of the gastrointestinal tract; upper gastrointestinal cancer is 1/7 as common as colon cancer. Benign gastrointestinal causes of anemia are iron malabsorption (atrophic gastritis, celiac disease, chronic inflammation, and bariatric surgery) and chronic blood loss due to gastrointestinal ulcerations...

In assessing exocrine pancreatic insufficiency (EPI), its diverse etiologies and the heterogeneous population affected should be considered. Diagnosing this condition remains a challenge in clinical practice especially for mild-to-moderate EPI, with the support of the time-consuming breath test or the coefficient of fat absorption. The fecal elastase-1 test, less precise for the diagnosis, cannot be useful for assessing treatment efficacy. Pancreatic enzyme replacement therapy (PERT) is the mainstay of treatment, whereby enteric-coated mini-microspheres are taken with every meal, in progressive doses based on an individual's weight and clinical symptoms...

Vitamin B12 deficiency is common among the elderly. Elderly people are particularly at risk of vitamin B12 deficiency because of the high prevalence of atrophic gastritis-associated food-cobalamin (vitamin B12) malabsorption, and the increasing prevalence of pernicious anaemia with advancing age. The deficiency most often goes unrecognised because the clinical manifestations are highly variable, often subtle and non-specific, but if left undiagnosed the consequences can be serious. Diagnosis of vitamin B12 deficiency, however, is not straightforward as laboratory tests have certain limitations...

BACKGROUND: Weight loss and malnutrition are poorly tolerated by geriatric patients, and pancreaticoduodenectomy (PD) can result in chronic malabsorption and weight loss. We sought to determine how preoperative severe nutritional risk (SNR), as defined by the American College of Surgeons National Surgical Quality Improvement Program/American Geriatric Society Best Practice Guidelines, affects long-term survival after PD for benign disease among geriatric and nongeriatric patients. STUDY DESIGN: All patients undergoing PD for nonmalignant conditions at a single center between 1995 and 2013 were followed for survival, excluding patients who died within 90 days of surgery...

BACKGROUND: There is proven therapeutic benefit in bariatric surgery for obese patients. Successful bariatric surgery will result in massive weight loss and ptotic skin, which can cause significant functional and psychological problems. As the incidence of bariatric surgery increases, so will the demand for plastic surgery. Currently, there is no evidence-based indication for massive weight loss body contouring, and therefore there is no standardized provision. METHODS: A prospective, multicenter, observational study of outcomes in 75 patients undergoing bariatric and plastic surgery procedures at two clinical sites was performed to determine whether the degree of ptosis can be determined by the type (malabsorptive or restrictive) of bariatric surgery and if the extent of disfigurement has an impact on psychological morbidity...
