Internal Spray Developed At Harvard Could Heal Gut Wounds

BOSTON (CBS) – Local researchers have developed a novel approach to help heal wounds “inside” the body. If you get a cut or a scratch on your skin, you can simply cover it with a bandage to help it heal, but there is no such remedy for wounds in the gut because it’s coated with a layer of mucus that prevents bandages from sticking. Now, researchers at the Wyss Institute at Harvard University are using gut bacteria to produce a probiotic hydrogel which could be sprayed onto a wound in the intestine to form a seal – like a spray-on bandage for the gut. This technology could one day be used to treat ulcers and wounds in people with inflammatory conditions of the GI tract, like Crohn’s disease, who currently have to take anti-inflammatory medications to keep their illness at bay.

Authors: Krajewska JB, Pietruszka P, Tomczyk D, Chen C, Owczarek A, Karolewicz B, Czapor-Irzabek H, Gorniak A, Fichna J Abstract Crohn's Disease (CD), one of the types of inflammatory bowel disease, poses a significant challenge to modern healthcare. This condition severely impacts patients' quality of life, and its incidence is continuously rising. Despite constant research, current treatment options are limited and largely unsuccessful and result in serious side effects, therefore new therapy alternatives are needed. Liposomal formulation provides a new hope for disease management. In our study, we characterized ...

AbstractPurposeThe aim of our study was to identify clinical parameters in recently diagnosed Crohn ’s disease (CD) patients for prediction of their disease course.MethodsEPIC (Early Predictive parameters of Immunosuppressive therapy in Crohn ’s disease) is a prospective, observational study in 341 patients with a recent CD diagnosis (≤ 6 months), and naïve to immunosuppressants (IS) and anti-tumor necrosis factor α (TNF) agents. Patient characteristics were documented up to 2 years. In line with national and international guid elines, a complicated disease course was defined as n...

A Case of Bacteriologically Determined De NovoTuberculosis during Tumor Necrosis Factor-α Inhibitor Therapy. Intern Med. 2019 Aug 21;: Authors: Takahashi G, Kobayashi H, Saito Y, Ohsawa S, Suzuki K, Ishihara S, Hisada T Abstract A 58-year-old man with Crohn's disease received adalimumab for 13 months after screening results for tuberculosis were found to be negative. He was diagnosed with de novo mediastinal lymph-node tuberculosis, which was proved to be bacteriologically identical to that of an individual with smear positive lung tuberculosis by a variable number of tandem repeat analyses. Afte...

Authors: Kim S, Kang Y, Park S, Koh H, Kim S Abstract BACKGROUND: It has been known that vitamin D level (serum 25[OH]D) has correlation with inflammatory bowel disease (IBD). The purpose of this study is to investigate changes of serum 25[OH]D in pediatric IBD patients according to the disease activity. METHODS: A total of 96 children and adolescent with IBD were enrolled in this retrospective study. Serologic inflammatory markers and clinical disease activity scores of the patients were collected, and their correlations with serum 25[OH]D were analyzed. Seasonal variations of serum 25[OH]D were also investiga...

Conclusions: Long diagnostic delay in IBD was mainly due to the longer delay in gastroenterologist consultation. Review of the referral system is needed to focus on measures to reduce long delays in diagnosis. The ileal location as a risk factor in CD and age older than 10 years as protective in UC should help recognition and early referral.

Children with inflammatory bowel disease (IBD) may be at higher risk for psychiatric disorders and suicide attempt, according to a large, population-basedstudy published inJAMA Pediatrics.The risk for psychiatric disorders and suicide among children with IBD was greater when compared with siblings without IBD, indicating that the risk is likely related to IBD itself and not to genetic or environmental factors shared with siblings."Particularly concerning is the increased risk of suicide attempt," wrote Agnieszka Butwicka, M.D., Ph.D., of the Karolinska Institute in Sweden and colleagues. "Long-term psycholog...

The Crohn’s-like lymphoid reaction (CLR) to colorectal cancer (CRC), a CRC-specific ectopic lymphoid reaction, is thought to play an important role in the host response to CRC. CLR is characterized by peritumoral lymphocytic aggregates that are found at the advancing edge of the tumor. Spatial and molecular characterization of CLR within the tumor microenvironment (TME) have uncovered a spectrum of peritumoral lymphoid aggregates with varying levels of organization and maturation. In early stages of CLR development, CD4+ T-cells cluster predominantly with mature antigen presenting dendritic cells. As CLR matures, inc...
