The aim of our study is to evaluate the prevalence of NSF in a cohort of patients on renal replacement treatment who underwent GBCA-enhanced magnetic resonance imaging (MRI). METHOD We retrospectively reviewed all the charts of kidney transplant (KT) recipients, patients on hemodialysis (HD) and peritoneal dialysis (PD) who received a uniform protocol for contrast material enhanced-MRI with gadoteric acid at our center from January 2004 to December 2017. RESULTS Three-hundred forty-four patients (44.1% on HD, 11.3% on PD and 44.4% KT recipients) underwent 551 gadoteric acid-enhanced MRI. The median age of the patients was 58 years (IQR, 45-70 years) and 65.1% were men. Sixty-three patients (18.3%) had skin punch biopsy after integumentary assessment performed by a dermatologist. No cases of NSF were detected after a median follow-up of 4.5 years (IQR, 1.9-8.2 years). During this period of observation, 116 (33.7%) patients died and 11 (3.1%) were lost at follow-up. CONCLUSIONS None of the patients exposed to gadoteric acid developed NSF. Our results, in line with more recent studies, suggest that the use of gadoteric acid, a macrocyclic GBCA, appears safe even in chronic kidney disease (CKD) patients receiving dialysis. Helicobacter pylori is a microorganism that in the last years has been associated with extragastric disorders such as respiratory diseases, however, its impact on lung is partially understood. The aim of this work was to study infection impact of H. pylori on the inflammatory markers expression at the pulmonary level using an animal model. Infection was performed by BALB/c wild type (WT) mice orotracheal instillation with 20 μl of 1 × 108H. pylori reference strain suspension once per day throughout 3 days. Inflammatory response was evaluated a
