Influence of smoking on disease activity and prognosis of ANCA-associated vasculitis: a retrospective cohort study.
Antineutrophil cytoplasmic antibody-associated vasculitides (AAV) are a group of autoimmune diseases characterized by inflammation of small blood vessels. Smoking is a potential trigger for such diseases, however, its link with AAV remains controversial. ⋯ Ever smoking is associated with increased AAV activity and more frequent renal replacement therapy and immunosuppressive treatment, resulting in a poorer survival prognosis in AAV patients. Future multicenter studies are required to further characterize the clinical, biological, and prognostic impact of smoking on AAV.

Relation between symptoms of insomnia, depression, sleep quality, anti-tumor necrosis factor therapy and disrupted circadian clock genes' expression in inflammatory bowel disease.
Inflammatory bowel disease (IBD) might be accompanied by emotional disturbances. Circadian rhythm genes, such as brain and muscle ARNT‑Like 1 (BMAL1), circadian locomotor output cycles kaput (CLOCK), neuronal PAS domain protein 2 (NPAS2), or nuclear receptor subfamily 1 group D member 1 (NR1D1) are related to inflammation and psychiatric symptoms that might modulate their expression. ⋯ Disruption of the clock gene expression might constitute a molecular background of sleep disorders and depression in IBD and might contribute to UC exacerbation.

Association of the ILR1 and FAS genes variants with a primary non-response to Anti-TNF therapy in Crohn's disease patients.
Crohn disease (CD) is a chronic inflammatory disease characterized by an uncontrolled immune response of the intestinal mucosal cells to antigens derived from the gut lumen. Specifically, the introduction of anti-tumor necrosis factor (TNF) drugs has changed the approach to the treatment of inflammatory bowel disease, and set new therapeutic goals, such as that of controlling clinical symptoms while simultaneously achieving complete endoscopic and mucosal remission. The mechanisms of action of anti-TNF drugs-and consequently the mechanisms of resistance to anti‑TNF therapy-are unknown. ⋯ In patients with CD treated with anti‑TNF drugs, complex pathways with multigene conditioning participate in the mechanism underlying treatment resistance. The genes involved in apoptosis, FAS and ILR1, seem to play an essential role in the lack of response to the treatment, and would be interesting objects of further population and functional research.
