Progression of Interstitial Lung Disease in Systemic Sclerosis: The Importance of Pneumoproteins Krebs von den Lungen 6 and CCL18.
To investigate the relationship between Krebs von den Lungen 6 (KL-6) and CCL18 levels and the severity and progression of systemic sclerosis (SSc)-related interstitial lung disease (ILD). ⋯ In a rigorously conducted clinical trial for SSc-related ILD, KL-6 and CCL18 levels correlated with ILD severity and declined with immunosuppression. Patients with higher baseline KL-6 and CCL18 levels were more likely to experience disease progression despite treatment. KL-6 and CCL18 levels could be used to identify patients with a progressive ILD phenotype who may benefit from a more aggressive initial treatment approach.

Multicenter Study Observational StudyComparative Study of Infliximab Versus Adalimumab in Refractory Uveitis due to Behçet's Disease: National Multicenter Study of 177 Cases.
To compare the efficacy of infliximab (IFX) versus adalimumab (ADA) as a first-line biologic drug over 1 year of treatment in a large series of patients with refractory uveitis due to Behçet's disease (BD). ⋯ Although both IFX and ADA are efficacious in refractory BD-related uveitis, ADA appears to be associated with better outcomes than IFX after 1 year of follow-up.

Magnetic Resonance Imaging of Lesions in the Sacroiliac Joints for Differentiation of Patients With Axial Spondyloarthritis From Control Subjects With or Without Pelvic or Buttock Pain: A Prospective, Cross-Sectional Study of 204 Participants.
To evaluate whether different types of sacroiliac (SI) joint lesions identified by magnetic resonance imaging (MRI) could differentiate axial spondyloarthritis (SpA) from conditions with buttock or pelvic pain attributable to other reasons, including postpartum women and healthy subjects. ⋯ BME and fat lesions were most pronounced in patients with axial SpA, but also occurred in other groups, particularly women with postpartum buttock/pelvic pain. Erosion above a certain SPARCC score threshold as well as backfill and ankylosis were highly specific for axial SpA.

Deletion of Mucosa-Associated Lymphoid Tissue Lymphoma Translocation Protein 1 in Mouse T Cells Protects Against Development of Autoimmune Arthritis but Leads to Spontaneous Osteoporosis.
Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT-1) plays a crucial role in innate and adaptive immune signaling by modulating the threshold for activation of immune cells, including Treg cells. Therefore, MALT-1 is regarded to be an interesting therapeutic target in several immune-mediated diseases. The goal of this study was to examine the role of MALT-1 in experimental animal models of rheumatoid arthritis (RA). ⋯ Overall, these data in murine models of RA highlight MALT-1 as a master regulator of T cell activation, which is relevant to the pathogenesis of autoimmune arthritis. Furthermore, these findings show that MALT-1 deficiency can lead to spontaneous osteoporosis, which is associated with impaired Treg cell numbers.
