Circulating Leptin Levels as a Potential Biomarker in Inflammatory Bowel Diseases: A Systematic Review and Meta-Analysis 

Larissa Gabriela Ferreira de Carvalho, MD, William Gustavo Lima, MD, Luiz Gonzaga Vaz Coelho, PhD, Valbert Nascimento Cardoso, PhD, Simone Od?lia Antunes Fernandes, PhD

doi : 10.1093/ibd/izaa037

Inflammatory Bowel Diseases, Volume 27, Issue 2, February 2021, Pages 169–181

The differential diagnosis of inflammatory bowel diseases (IBDs) between Crohn’s disease (CD) and ulcerative colitis (UC) is important for designing an effective therapeutic regimen. However, without any adequate gold standard method for differential diagnosis currently, therapeutic design remains a major challenge in clinical practice. In this context, recent studies have showed that circulating leptin stands out as a potential biomarker for the categorization of IBDs. Thus, we aimed to summarize the current understanding of the prognostic and diagnostic value of serum leptin in patients with IBDs.

Inflammatory Bowel Diseases, Volume 27, Issue 2, February 2021, Pages 256–267

Defining epithelial cell contributions to inflammatory bowel disease (IBD) is essential for the development of much needed therapies for barrier repair. Children with very early onset (VEO)-IBD have more extensive, severe, and refractory disease than older children and adults with IBD and, in some cases, have defective barrier function. We therefore evaluated functional and transcriptomic differences between pediatric IBD (VEO and older onset) and non-IBD epithelium using 3-dimensional, biopsy-derived organoids.

Endocytosis of Intestinal Tight Junction Proteins: In Time and Space 

Prashant Nighot, MVSc, PhD, Thomas Ma, MD, PhD

doi : 10.1093/ibd/izaa141

Inflammatory Bowel Diseases, Volume 27, Issue 2, February 2021, Pages 283–290

Eukaryotic cells take up macromolecules and particles from the surrounding milieu and also internalize membrane proteins via a precise process of endocytosis. The role of endocytosis in diverse physiological processes such as cell adhesion, cell signaling, tissue remodeling, and healing is well recognized. The epithelial tight junctions (TJs), present at the apical lateral membrane, play a key role in cell adhesion and regulation of paracellular pathway. These vital functions of the TJ are achieved through the dynamic regulation of the presence of pore and barrier-forming proteins within the TJ complex on the plasma membrane. In response to various intracellular and extracellular clues, the TJ complexes are actively regulated by intracellular trafficking. The intracellular trafficking consists of endocytosis and recycling cargos to the plasma membrane or targeting them to the lysosomes for degradation. Increased intestinal TJ permeability is a pathological factor in inflammatory bowel disease (IBD), and the TJ permeability could be increased due to the altered endocytosis or recycling of TJ proteins. This review discusses the current information on endocytosis of intestinal epithelial TJ proteins. The knowledge of the endocytic regulation of the epithelial TJ barrier will provide further understanding of pathogenesis and potential targets for IBD and a wide variety of human disease conditions.

Should We Be Screening for SARS-CoV-2 in IBD Patients Before Initiation of Biologic Therapy? 

Jana G Hashash, MD, MSc, Suha Jabak, MD, Fadi F Francis, MD, Miguel Regueiro, MD

doi : 10.1093/ibd/izaa173

Inflammatory Bowel Diseases, Volume 27, Issue 2, February 2021, Pages 291–294

Before initiation of biologic therapy, current guidelines recommend screening for hepatitis B virus, human immunodeficiency virus, and latent mycobacterium tuberculosis infections.1,2 It is also recommended to screen for susceptibility to primary varicella zoster virus (VZV) infection, and it is suggested to check for hepatitis C virus infection. With the current coronavirus disease 2019 (COVID-19) pandemic and the high prevalence of asymptomatic infected individuals, the question is raised as to whether or not we need to check for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection before initiation of biological therapy in inflammatory bowel disease (IBD) patients.

Inflammatory Bowel Diseases, Volume 27, Issue 2, February 2021, Pages e20–e22

Infliximab is a tumor necrosis factor (TNF) antagonist effective for Crohn’s disease (CD), with variable pharmacokinetics (pK) and increased drug clearance in active disease and hypoalbuminemia. Tacrolimus is a calcineurin inhibitor and nonbiologic immunosuppressant that has been studied in CD 1, 2. We hypothesized that in patients with nonmechanistic failure of infliximab (low or absent drug level without antidrug antibodies), the addition of tacrolimus may reduce inflammatory burden, improve hypoalbuminemia, alter the pK and clearance of the biologic, and result in therapeutic biologic drug levels. We hypothesized that after achieving therapeutic biologic drug levels, we could discontinue tacrolimus and maintain response with the biologic

Inflammatory Bowel Diseases, Volume 27, Issue 2, February 2021, Pages e23–e24

Some cases of pyoderma gangrenosum can be extremely challenging, especially because there is no robust evidence regarding the best therapeutic options. We assisted a female patient aged 44 years who was previously colostomized after resection of a sigmoid tumor and presented with low digestive hemorrhage. A colonoscopy was performed (Supplementary Fig. 1) showing moderate colitis in the excluded colon. She reported Crohn disease with no treatment, so we started a mesalamine enema, which yielded a good response.
