Intestinal dysbiosis remains the focus of research into the pathogenesis of chronic inflammatory bowel disease (IBD). The potential role of gut microbiota in the development of IBD includes interaction with the host genome and immune system, as well as various environmental factors, diet, drugs, industrialization, etc. Other organs are negatively affected by intestinal dysbiosis via gut-brain axis. The composition of microbiota and its metabolic activity has a significant impact on the effectiveness of anti-inflammatory therapies. Microbiome-based treatment for IBD includes the use of diet, antibiotics, pre-, pro- and synbiotics, and faecal transplantation (FMT). The development of effective therapies for IBD patients will only be possible once the interactions between the microbiota and its metabolites and the host immune system are better understood.

Background: Self-reported health problems following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are common and often include relatively non-specific complaints such as fatigue, exertional dyspnoea, concentration or memory disturbance and sleep problems. The long-term prognosis of such post-acute sequelae of COVID-19/post-COVID-19 syndrome (PCS) is unknown, and data finding and correlating organ dysfunction and pathology with self-reported symptoms in patients with non-recovery from PCS is scarce. We wanted to describe clinical characteristics and diagnostic findings among patients with PCS persisting for >1 year and assessed risk factors for PCS persistence versus improvement.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease, characterized by eczematous skin lesions and pruritus. There is an unmet need for effective first-line systemic therapies with good safety profiles, particularly oral medications. Orismilast is a novel first-in-class oral phosphodiesterase-4 (PDE4) B/D inhibitor under investigation for the treatment of moderate-to-severe AD.

Chronic inflammation is a common trait in the pathogenesis of several diseases of the gut, including inflammatory bowel disease and celiac disease. Control of the inflammatory response is crucial in these pathologies to avoid tissue destruction and loss of intestinal function. Over the last 50 years, the identification of the mechanisms and mediators involved in the acute phase of the inflammatory response, which is characterized by massive leukocyte recruitment, has led to a number of therapeutic options.

Background: Mitochondria-driven oxidative/redox stress and inflammation play a major role in chronic kidney disease (CKD) pathophysiology. Compounds targeting mitochondrial metabolism may improve mitochondrial function, inflammation, and redox stress; however, there is limited evidence of their efficacy in CKD.
Methods: We conducted a pilot randomized, double-blind, placebo-controlled crossover trial comparing the effects of 1200 mg/day of coenzyme Q10 (CoQ10) or 1000 mg/day of nicotinamide riboside (NR) supplementation to placebo in 25 people with moderate-to-severe CKD (estimated glomerular filtration rate [eGFR] <60mL/min/1.
