The role of histopathology in the diagnosis and management of coeliac disease and other malabsorptive conditions.

Histopathology 2021 Jan;78(1):88-105

Envoi Specialist Pathologists, University of Queensland, Brisbane, Queensland, Australia.

Most absorption of nutrients takes place in the proximal small intestine, and the most common disorders leading to malabsorption are associated with a morphological abnormality in the duodenal mucosa that is appreciable in histological sections of biopsy specimens. Coeliac disease is the most well-known example, causing intraepithelial lymphocytosis, inflammation and villous atrophy in the duodenum. Remarkably similar inflammatory changes can be induced by other processes, including medications, e. Read More

Enterotoxigenic Escherichia coli Infections.

Curr Infect Dis Rep 2019 Mar 4;21(3). Epub 2019 Mar 4.

Department of Medicine, Division of Infectious Diseases, Washington University School of Medicine, 660 South Euclid Avenue, Saint Louis, MO, 63110, USA.

Purpose Of Review: Review recent developments pertaining to the epidemiology, molecular pathogenesis, and sequelae of enterotoxigenic Escherichia coli (ETEC) infections in addition to discussion of challenges for vaccinology.

Recent Findings: ETEC are a major cause of diarrheal illness in resource poor areas of the world where they contribute to unacceptable morbidity and continued mortality particularly among young children; yet, precise epidemiologic estimates of their contribution to death and chronic disease have been difficult to obtain. Although most pathogenesis studies, and consequently vaccine development have focused intensively on canonical antigens, more recently identified molecules unique to the ETEC pathovar may inform our understanding of ETEC virulence, and the approach to broadly protective vaccines.

Tropical Enteropathies.

Curr Gastroenterol Rep 2017 Jul;19(7):29

Blizard Institute, Barts & The London School of Medicine, Queen Mary University of London, Newark Street, London, E1 2AT, UK.

Purpose Of Review: The term 'tropical enteropathy' originated in observations in the 1960s that small intestinal morphology and function differed in the tropics from the norms found in temperate climates. It was subsequently shown that this enteropathy is more closely related to environmental conditions than latitude, and it was re-labelled 'environmental enteropathy'. It is now recognised that environmental enteropathy (also now called environmental enteric dysfunction) has implications for the health and linear growth of children in low- and middle-income countries, and it may underlie poor responses to oral vaccination in these countries.

Post-infectious IBS, tropical sprue and small intestinal bacterial overgrowth: the missing link.

Nat Rev Gastroenterol Hepatol 2017 Jul 17;14(7):435-441. Epub 2017 May 17.

Department of Medicine, Yong Loo Lin School of Medicine, National University of Singapore, 6A Napier Road, Singapore, 258500.

Evidence is emerging that IBS, a hitherto enigmatic disorder thought to be predominantly related to psychological factors, has a microorganic basis in a subset of patients with the disease. Post-infectious IBS (PI-IBS), commonly of the diarrhoea-predominant subtype (defined as new development of IBS following acute infectious diarrhoea), is one such condition known to occur in up to 10-30% individuals after acute gastroenteritis. However, following acute infectious gastroenteritis, patients can also develop post-infectious malabsorption syndrome (PI-MAS), popularly known as tropical sprue. Read More

Small Intestinal Bacterial Overgrowth and Other Intestinal Disorders.

Gastroenterol Clin North Am 2017 03;46(1):103-120

Department of Microbiology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow 226014, India.

Gut microbiota is the largest organ of the human body. Although growth of bacteria more than 10 colony forming unit (CFU) per milliliter in culture of upper gut aspirate is used to diagnosis small intestinal bacterial overgrowth (SIBO), 10 CFU or more is being considered to suggest the diagnosis, particularly if colonic type bacteria are present in the upper gut. Although neither very sensitive nor specific, hydrogen breath tests are widely used to diagnose SIBO. Read More

Immunohistochemical Expression of Antitissue Transglutaminase 2 in Tissue Injuries: An Interpretation Beyond Celiac Disease.

Appl Immunohistochem Mol Morphol 2018 Jul;26(6):425-430

Departments of Gastroenterology and Human Nutrition, Pathology, and Nephrology, All India Institute of Medical Sciences, New Delhi, India.

Tissue transglutaminase 2 enzyme plays a diverse role in intracellular and extracellular functioning. Aberrant expression of anti-TG2 antibody has recently been proposed for extraintestinal identification of celiac disease (CeD), but its utility is questionable. To examine whether anti-TG2 immunohistochemical (IHC) staining can be of diagnostic value in identifying extraintestinal involvement in CeD, tissue blocks of patients with IgA nephropathies (IgAN), minimal change disease, membranous glomerulonephritis, membrano-proliferative glomerulonephritis, normal kidney, intestinal biopsies from CeD, tropical sprue, nonspecific duodenitis, and inflammatory bowel disease; liver biopsies from patients with chronic hepatitis B and C, acute liver failure (ALF), and CeD-associated liver diseases were retrieved and subjected to IHC staining for anti-tissue transglutaminase 2 enzyme.
