Background: The gut microbiome plays a crucial role in the pathogenesis and progression of inflammatory bowel disease (IBD). Understanding the dynamics of the gut microbiome in relation to treatment can provide valuable insights into disease management and therapy strategies. The aim of this study is to investigate if diversity and composition of the gut microbiome correlate with time since treatment and disease activity during maintenance infliximab (IFX) therapy among children with IBD.

Article Synopsis
  • Pediatric-onset immune-mediated inflammatory disease (pIMID) significantly raises the long-term risk of various cancers compared to non-affected individuals, with a twofold increase in cancer risk observed.
  • A study involving 12,664 pIMID patients revealed that treatments like thiopurines and anti-TNFα are linked to a markedly higher risk of developing lymphoma and skin cancer.
  • The findings emphasize the need for tailored immunotherapy and ongoing cancer monitoring for those diagnosed with pIMID.

Article Synopsis
  • Thiopurine therapy is commonly used to treat inflammatory bowel disease (IBD), but this study investigates the relationship between thiopurines and cancer risk in IBD patients based on their drug usage and age.
  • An analysis of data from 43,419 IBD patients showed that cancer risk was elevated across all age groups and increased with both monotherapy and combination therapy, particularly in patients over 65 years.
  • The risk of developing cancer linked to thiopurines decreased back to normal levels once patients stopped taking the medication, indicating a potential concern for long-term users but also a reassuring aspect regarding the risks after discontinuation.

Background: Pediatric-onset ulcerative colitis (pUC) represents a more aggressive disease phenotype compared with adult-onset UC. We hypothesized that this difference can, in part, be explained by the composition of the microbiota.

Methods: In a prospective, longitudinal study, we included pediatric (N = 30) and adult (N = 30) patients with newly or previously (>1 year) diagnosed UC.

Improved biomarkers are needed for pediatric inflammatory bowel disease. Here we identify a diagnostic lipidomic signature for pediatric inflammatory bowel disease by analyzing blood samples from a discovery cohort of incident treatment-naïve pediatric patients and validating findings in an independent inception cohort. The lipidomic signature comprising of only lactosyl ceramide (d18:1/16:0) and phosphatidylcholine (18:0p/22:6) improves the diagnostic prediction compared with high-sensitivity C-reactive protein.

Objectives: We aimed to identify pre- and perinatal risk factors for developing pediatric-onset immune-mediated inflammatory (pIMID).

Methods: This nation-wide, cohort study included all children born in Denmark from 1994 to 2014 identified from the Danish Medical Birth registry. Individuals were followed through 2014 and cross-linked to the continuously updated national socioeconomic and healthcare registers to obtain data on pre- and perinatal exposures (maternal age, educational level, smoking, maternal IMID, parity, mode of conception and delivery, plurality, child's sex, and birth season).

Objectives: Pediatric-onset inflammatory bowel disease (pIBD) increases the risk of developing several different cancer forms. In this case-control study, we aimed to assess the impact of medical treatment and disease activity on the risk of developing disease-associated cancer (DAC) and treatment-associated cancer (TAC).

Methods: In a previous study, we identified 27 cases of DAC (colorectal cancer, small bowel cancer, and cholangiocarcinoma) and 28 TAC (lymphoma and skin cancer) in 6689 patients with pIBD in Denmark and Finland during the period 1992-2015.

Background: Incidence rates of inflammatory bowel disease [IBD] reported from developed countries are rising, with some levelling out. The aim of this study was to assess the disease burden of IBD by estimating the incidence and prevalence across age groups and projecting these to 2030 in a high-incidence country.

Methods: Using an algorithm [incorporating ICD codes, medications and histopathology], patients [n = 69 862] diagnosed with Crohn's disease [CD] or ulcerative colitis [UC] between 1980 and 2017 were identified in the Danish National Patient Registry and included in a nationwide cohort.

Terpenes are one of the largest classes of secondary metabolites that occur in all kingdoms of life and offer diverse valuable properties for food and pharma industry including pleasant odor or taste as well as antimicrobial or anticancer activities. A multitude of terpene biosynthesis pathways are known, but their efficient biotechnological exploitation requires an adequate microorganism as host which can ideally provide an optimal supply with biosynthetic isoprene precursors. Rhodobacter capsulatus, a Gram-negative, facultative anaerobic, photosynthetic non-sulfur purple bacterium belonging to the α-proteobacteria represents such a host particularly suitable for terpene production.

Because it is the precursor for various essential cellular components, the amino acid serine is indispensable for every living organism. In plants, serine is synthesized by two major pathways: photorespiration and the phosphorylated pathway of serine biosynthesis (PPSB). However, the importance of these pathways in providing serine for plant development is not fully understood.

Article Synopsis
  • The study investigates the role of microRNAs (miRNAs) in disease severity of ulcerative colitis (UC) in pediatric versus adult patients, focusing on different expression levels of specific miRNAs.
  • It was found that adult patients exhibited higher levels of miR-21, while certain miRNAs (miR-31 and miR-155) showed an inverse correlation with disease severity, particularly among the pediatric group.
  • The findings suggest that miRNA expression varies with the patient’s age and disease severity, indicating their potential use as biomarkers for monitoring UC inflammation.
