Introduction: Coronavirus disease (COVID-19) has spread from Wuhan, China, and become a worldwide pandemic. Most patients display respiratory symptoms but up to 50% report gastrointestinal symptoms. Neopterin is a surrogate marker for viral inflammation, and its production by macrophages is driven by interferon-γ.
Methods: We measured fecal neopterin in 37 hospitalized COVID-19 patients not requiring intensive care measures and 22 healthy controls.
Results: Fecal neopterin was elevated in stool samples from COVID-19 patients compared with that in samples from healthy controls. Especially, patients reporting gastrointestinal symptoms exhibited increased fecal neopterin values.
Discussion: COVID-19 is associated with an inflammatory immune response in the gastrointestinal tract.

The increased burden of non-communicable diseases (NCDs) is fueled by lifestyle factors including diet. This cross-sectional study explored among Tanzanian adults whether unhealthy dietary patterns are associated with intestinal and systemic inflammation which could increase the risk of NCDs. The study included 574 participants, with both diet and inflammatory markers data.

Aim: Novel markers to reflect the intestinal damage in coeliac disease are needed. We studied the potential of faecal and serum neopterin, and faecal myeloperoxidase, human β-defensin-2, and lipocalin-2 in a case-control study.
Methods: Data were collected from medical records and a biobank including newly diagnosed coeliac disease patients, potential coeliac disease patients and non-coeliac controls.

Background: Validated biomarkers could catalyze environmental enteric dysfunction (EED) research.
Objectives: Leveraging an EED histology scoring system, this multicountry analysis examined biomarker associations with duodenal histology features among children with EED. We also examined differences in 2-h compared with 1-h urine collections in the lactulose rhamnose (LR) dual sugar test.

Article Synopsis
- The study investigates the potential of using stool samples as non-invasive biomarkers to evaluate small intestinal damage in conditions like coeliac disease and environmental enteropathy, where traditional biopsy methods are currently used.
- A systematic search led to the inclusion of 35 relevant studies focusing on various faecal markers, such as faecal calprotectin and antibodies related to gluten sensitivity, which showed mixed results in their reliability for assessment.
- The authors conclude that more research is necessary to identify consistent and reliable faecal biomarkers that can accurately reflect small intestinal mucosal damage, particularly in environmental enteropathy.
Malnutrition enteropathy in Zambian and Zimbabwean children with severe acute malnutrition: A multi-arm randomized phase II trial.

Article Synopsis
- Malnutrition is a major cause of child deaths globally, with Severe Acute Malnutrition (SAM) leading to high mortality rates, especially when compounded by infections or medical complications.
- A clinical trial conducted in Zambia and Zimbabwe evaluated four potential treatments for malnutrition-related enteropathy in 125 hospitalized children aged 6-59 months with SAM, comparing bovine colostrum, N-acetyl glucosamine, teduglutide, budesonide, and standard care over 14 days.
- Results indicated that teduglutide significantly reduced mucosal damage biomarkers, suggesting it may be a beneficial treatment for enteropathy in children with complicated malnutrition, with all interventions deemed safe.
