Interleukin-22 and interleukin-22-producing NKp44+ natural killer cells in subclinical gut inflammation in ankylosing spondylitis

Objective The intestinal inflammation observed in patients with ankylosing spondylitis (AS) is characterized by an overexpression of interleukin-23 (IL-23). IL-23 is known to regulate IL-22 production through lamina propria NKp44+ natural killer (NK) cells, which are thought to be involved in protective mucosal mechanisms. This study was undertaken to evaluate the frequency of NKp44+ NK cells and the expression of IL-22 in the ileum of AS patients. Methods Tissue NKp44+ NK cells, NKp46+ NK cells, and IL-22–producing cells were analyzed by flow cytometry. Quantitative gene expression analysis of IL-22, IL-23, IL-17, STAT-3, and mucin 1 (MUC-1) was performed by reverse transcriptase–polymeras…

Subcutaneous emphysema, pneumomediastinum and pneumoperitoneum after diagnostic colonoscopy for ulcerative colitis: a rare but possible complication in patients with multiple risk factors

Dear Editor: Colonoscopy is regarded as a safe procedure, but complications may occur. The most dreaded are perforation and massive bleeding of the colon. The incidence of perforation is low but, despite increased experience with the procedure, it remains unchanged over time and in a large population study ranges from 0.6 to 1 per 1.000 procedures, depending on the centre and the data source. Few studies have assessed risk factors for colonoscopy-related bleeding and perforation. Gatto et al. have reported that there was a significant trend in the incidence of perforation with increasing age, people aged 75 years or older having a fourfold risk as compared to those aged 65–69 years; same re…
