Use of 18F-fluorodeoxyglucose positron emission tomography-computed tomography in patients affected by polymyalgia rheumatica and persistent increase…

Polymyalgia rheumatica (PMR) is an inflammatory disease affecting older adults characterized by aching pain and morning stiffness of the shoulder and pelvic girdles. Moreover, PMR can be associated with giant cell arteritis (GCA). Generally, PMR is highly responsive to steroids, reaching complete remission in the majority of cases. However, the possibility of occult diseases, including extra-cranial GCA, should be excluded. 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) is able to detect the presence of peri-/articular or vascular inflammation, which may be both present in PMR, thus representing a useful diagnostic tool, mainly in presence of extra-cranial GCA. We retrosp…
IL-9 IN PsA
2016
Objective. To investigate the expression and tis- sue distribution of Th9-related cytokines in patients with psoriatic arthritis (PsA). Methods. Quantitative gene expression analysis of Th1, Th17, and Th9 cytokines was performed in intestinal biopsy samples obtained from patients with PsA, HLA2B272positive patients with ankylosing spondylitis (AS), patients with Crohn’s disease (CD), and healthy controls. Expression and tissue distribu- tion of interleukin-23 (IL-23), IL-17, IL-22, IL-9, and IL-9 receptor (IL-9R) were evaluated by immunohisto- chemistry and confocal microscopy. Flow cytometry was used to study the frequency of Th9 cells among periph- eral blood, lamina propria, and synovial…
Interleukin 9 neutralisation reduces collagen-induced arthritis severity in mouse models.
2021
Objective Interleukin 9 (IL-9) is a mediator of tissue damage in several inflammatory diseases. In this study we aimed to evaluate the effects of in vivo IL-9 neutralisation in mice developing collagen induced arthritis (CIA). Methods DBA/1 were immunised with collagen in Freund’s complete adjuvant (CFA) to induce arthritis. Anti-IL-9 mAb was injected in mice after the onset of arthritis (Group A) or on the same day as sensitisation and again on the day of the challenge (Group B). Histological analysis was performed in joints of mice and spleen cells were also analysed by flow cytometry. A geneset analysis was carried out on whole tarsal joint tissue transcriptomes. Results IL-9 was over-ex…
