OBJECTIVES: In rheumatoid arthritis (RA), seropositive and seronegative disease may be two entities with different underlying pathophysiological mechanisms, long-term outcomes and disease presentations. However, the effect of the conjoint presence of multiple autoantibodies, as proxy for a more pronounced humoral autoimmune response, on clinical phenotype remains unclear. Therefore, this study investigates the association between the number of autoantibodies and initial clinical presentation in two independent cohorts of patients with early RA...

OBJECTIVES: Studies suggest that rheumatoid arthritis (RA)-related autoimmunity is initiated at a mucosal site. However, the factors associated with the mucosal generation of this autoimmunity are unknown, especially in individuals who are at-risk for future RA. Therefore, we tested anti-cyclic citrullinated peptide (anti-CCP) antibodies in the sputum of RA-free first-degree relatives (FDRs) of RA patients and patients with classifiable RA. METHODS: We evaluated induced sputum and serum from 67 FDRs and 20 RA subjects for anti-CCP-IgA and anti-CCP-IgG, with cut-off levels for positivity determined in a control population...

OBJECTIVES: Juvenile idiopathic arthritis (JIA) is a heterogeneous group of diseases, comprising seven categories. Genetic data could potentially be used to help redefine JIA categories and improve the current classification system. The human leucocyte antigen (HLA) region is strongly associated with JIA. Fine-mapping of the region was performed to look for similarities and differences in HLA associations between the JIA categories and define correspondences with adult inflammatory arthritides...

OBJECTIVES: Pentraxin 3 (PTX3) is a locally produced multifunctional protein involved in inflammation, matrix deposition, and immunity. As patients with seropositive rheumatoid arthritis (RA) have a more severe disease course and higher risk of joint destruction than seronegative patients, the aim of the present study was to examine differences in PTX3 in synovial fluid (SF) (and serum) in seropositive compared to seronegative RA, and other local markers of inflammation and destruction...

Although skin-mucosa lesions are common in almost all patients with Behçet syndrome (BS), clinical properties may differ from one patient to another. Within BS, there are subsets with different organ involvement and hence probably different pathological pathways. These subsets can be described as a) solo skin-mucosa disease with no major organ involvement, b) eye disease, c) seronegative spondyloarthropathy-like disease (arthritis, enthesopathy, and folliculitis), d) Crohn-like disease, and finally the topic of this chapter: e) vascular disease...

OBJECTIVES: Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome, rheumatoid arthritis (RA), ankylosing spondylitis (AS), and seronegative spondyloarthropathy (SPA) are autoimmune diseases of unknown etiology, which share some clinical manifestations in common. Previous family-based investigations support genetic contributions to the susceptibility of these diseases. The current study evaluated whether three previously reported AS-associated single-nucleotide polymorphisms (SNPs), rs6908425 T>C in CDKAL1, rs11584383 T>C near KIF21B, and rs11175593 C>T near LRRK2/MUC19, have any genetic overlap across multiple autoimmune diseases including SAPHO syndrome, RA, AS, and SPA...

Chikungunya alphavirus has caused large epidemics worldwide and leads to acute incapacitating polyarthralgia. The inflammatory reaction over several days will drive robust innate and humoral responses essential to control the infection. Critically, fatal cases and mother-to-child transmission have also been described. Chikungunya can give rise to chronic musculoskeletal diseases, which can last for months to years, particularly in elderly individuals, and occasionally leads to seronegative rheumatoid arthritis-like pathologies...

BACKGROUND: Increasing vascular endothelial growth factor (VEGF) has been reported in remitting symmetrical seronegative synovitis with pitting edema (RS3PE) syndrome, rheumatoid arthritis (RA), polymyalgia rheumatica (PMR) and giant cell arteritis (GCA). The aim of this study was to compare VEGF levels in patients over 60 years of age who have RS3PE, RA, PMR or GCA so as to determine whether elevated VEGF is specific for a rheumatic disease, the inflammation or edema that occurs with these pathological conditions...

We describe the case of a 32-year-old male with previous history of subacute cutaneous lupus erythematosus (SCLE) who presented with arthritis followed by a unilateral lower-limb sensorimotor impairment, without biochemical or immunological marker abnormalities. Our patient currently satisfies only three of the systemic lupus international collaborating clinics criteria. Management of such patients is challenging due to lack of examples in the literature, with this case being the first described where a seronegative patient with SCLE demonstrated neurological involvement...

The inflammatory arthropathies share in common their tendency to produce marked alterations in skeletal remodelling and architecture. This review will focus on RA and the seronegative spondyloarthopathies (SpA), which share common features with respect to their tendency to produce localized bone destruction at sites of articular and peri-articular inflammation. However, there are significant differences in the skeletal pathology in these conditions, which include the unique involvement of the axial skeleton and the presence of inflammation in the extra-articular entheses in SpA...

A 72-year-old woman presented 9 months ago with skin rash on her bilateral forearms, which was followed by intermittent high fever, and stiffness and swelling of her bilateral fingers. She was diagnosed with seronegative rheumatoid arthritis (RA). She had a past history of breast cancer and had undergone breast preservation surgery 13 years previously. During admission in our hospital, she developed high fever and leukocytosis with a relapsing skin rash, sore throat, polyarthralgia and increased levels of serum ALT/AST and ferritin, all of which fulfilled Yamaguchi's criteria for adult-onset Still's disease (AOSD)...

OBJECTIVES: The diagnostic diversity of polymyalgia rheumatica (PMR) can easily be obscured by the widespread use of corticosteroids (CSs) early in the disease course. This study observed the course of PMR without CSs and determined whether alternative medication could be useful. METHODS: Seventy patients with new-onset PMR comprised phase 1. Eight were removed with specific diagnoses (four with giant cell arteritis [GCA]). The remaining 62 were treated with nonsteroidal anti-inflammatory drugs (NSAIDs) alone until enough time had elapsed to ascertain whether their PMR had evolved into another rheumatologic inflammatory condition...
