Introduction: Celiac disease (CD) is an autoimmunological gluten sensitive enteropathy occuring to genetically predisposed individuals. Active CD is accompanied by presence of multiple antibodies. Anti alpha enolase antibodies were reported in several autoimmunological disorders like rheumatoid arthritis, primary sclerosing cholangitis. Data about its presence and role in CD is avaricious.
Aim: The aim of this study was to determine presence of anti alpha enolase antibodies in CD, correlation with gluten exposure, presence of anti tranglutaminase antibodies and Marsh scale.
Methods: Sera from 31 patients with CD (21 females, 10 males) and 6 healthy subjects were collected. Evaluation of CD activity and adherence to gluten free diet were obtained by serology tests (presence of endomyslum antibodies and/or anti transglutamineses in IgA or IgG classes) and histological hallmarks. Anti alpha enolase antibodies were identified in sera using ELISA kit. Titres of anti alpha enolase antibodies were identified among patients with newly diagnosed CD, CD patients non adhering to gluten free diet (GFD), adhering to GFD and among healthy subjects.
Results: Mean titre of anti alpha enolase antibodies was higher in CD patients (both treated and non treated) in comparison to control group, respectively 1.1 ng/mL, and 0.795 ngl mL. Among CD patients non adhering to gluten free diet mean titre was 1.4 ng/mL.
Conclusions: Higher anti alpha enolase antibodies titres in non treated CD suggest usefulness of its measurement. These antibodies might be a novel marker of chronic inflammation among CD patients non adhering to GFD.

Targeting optimal glycemic control based on hemoglobin A1c (A1c) values reduces but does not abolish the onset of diabetic kidney disease and its progression to chronic kidney disease (CKD). This suggests that factors other than the average glucose contribute to the residual risk. Vitamin D deficiency and frequent episodes of acute hyperglycemia (AH) are associated with the onset of albuminuria and CKD progression in diabetes.

Background/aims: The objectives of this real-world study were to determine 1-year persistence with vedolizumab in patients with ulcerative colitis and to evaluate factors contributing to loss of response.
Methods: In this multicenter, retrospective, observational chart review, patients with moderately to severely active ulcerative colitis who received ≥ 1 dose of vedolizumab in clinical practice at 16 tertiary hospitals in Japan (from December 2018 through February 2020) were enrolled.
Results: Persistence with vedolizumab was 64.

Bacterial adaptive immunity, driven by CRISPR-Cas systems, protects against foreign nucleic acids from mobile genetic elements (MGEs), like bacteriophages. The type I-E CRISPR-Cas system employs the Cascade (CRISPR-associated complex for antiviral defense) complex for target DNA cleavage, guided by crRNA. Anti-CRISPR (Acr) proteins, such as AcrIE7, counteract this defense by inhibiting Cascade activity.

Background: The significant distal necrosis of the random-pattern skin flaps greatly restricts their clinical applications in flap transplantation. Previous studies have demonstrated the potential of danshensu (DSS) to alleviate ischemic tissue injury. However, no research to date has confirmed whether DSS can improve the survival of ischemic flaps.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by itching and redness, affecting individuals of all ages and significantly impairing their quality of life. The prevalence of AD is rising, posing serious health concern. Relief of itching is a primary treatment objective; however, steroid treatments can lead to adverse effects, including skin barrier thinning.
