BACKGROUND: Seropositive rheumatoid arthritis (RA) is characterized by autoantibodies binding to citrullinated and homocitrullinated proteins. We wanted to study the expression patterns of these disease-associated protein forms and if the rheumatoid nodule and synovial tissue itself contain biologically active levels of citrullinating peptidyl arginine deiminases 2, 3 and 4 and homocitrullination-facilitating neutrophil enzyme myeloperoxidase. METHOD: Total of 195 synovial samples from metatarsal joints from five ACPA/RF-positive RA patients (n = 77), synovial samples from knees of eight seropositive RA (n = 60), seven seronegative RA (n = 33) and five osteoarthritis (n = 25) patients were analyzed for citrulline and homocitrulline contents using HPLC...

INTRODUCTION: Autoimmune disorders have been documented in solid tumors and malignant hematological disorders. They are very common and well studied in lymphomas which are associated with immune imbalance. They are less common in solid tumors and are categorized as paraneoplastic syndromes with unclear pathogenesis. AIM: The aim of the present study was to find the frequency of autoimmune phenomena in solid tumors of various origin, location and status of the tumor...

Tumor necrosis factor alpha (TNF alpha) antagonists are biologic agents used in the management of inflammatory conditions such as rheumatoid arthritis, seronegative spondyloarthropathies and inflammatory bowel disease. These agents have been recently shown to cause a syndrome called anti-TNF induced lupus (ATIL), a rare condition which has similar clinical manifestations to idiopathic systemic lupus erythematosus (SLE). Given that extra-intestinal manifestations of inflammatory bowel disease include arthritis, it can be difficult to separate arthritis due to underlying disease from drug-induced arthritis...

Methotrexate forms one of the main drugs in the pharmacological management of rheumatoid arthritis, psoriasis, and some neoplastic diseases. Methotrexate rarely causes cutaneous ulceration and most cases are reported in patients with psoriasis and have been accompanied by pancytopenia. The author here reports occurrence of multiple (two) cutaneous ulcers due to methotrexate in a nonpsoriatic patient. The patient was on methotrexate for seronegative rheumatoid arthritis for 10 years. To the best of the Author's knowledge, this is a rare case of cutaneous ulceration due to methotrexate in a nonpsoriatic patient reported in the literature so far, and probably one of its kind without pancytopenia or other hematological abnormalities...

BACKGROUND: The aim was to identify novel diagnostic autoantibody candidates for rheumatoid arthritis (RA) by comprehensive screening for autoreactivity. METHOD: We incubated 5892 recombinant proteins coupled to fluorescent beads, with patients' sera for the detection of IgG-autoantibodies in three independent patient cohorts: A (n = 72 patients with established RA); B/B- (n = 116 patients with early RA (B) and n = 51 CCP-negative patients with early RA from B (B-)); and C (n = 184 patients with early seronegative RA), in comparison to matched healthy controls...

Developments and improvements in knowledge are rapid and ongoing in both the radiologic and rheumatologic fields. During the past decade, the roles of imaging and the radiologist in the assessment and management of many inflammatory rheumatologic diseases have undergone several changes. To remain effective in patient care, the radiologist needs to be aware of these changes when recommending and interpreting imaging examinations for the referring physician. The goal of contemporary rheumatoid arthritis (RA) management is to redefine RA as a disease that is no longer characterized by erosions, which reflect established or long-standing untreated disease...

OBJECTIVE: In the case of high erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, the diagnosis of the underlying disease can be challenging especially in serologically unrevealing patients who have nonspecific clinical findings. We aimed to investigate the final distribution of definitive diagnoses in patients who initially presented with nonspecific clinical findings and sustained elevations in serum ESR/CRP levels. MATERIAL AND METHODS: The medical records of patients hospitalized in a rheumatology clinic between January 2010 and January 2011 were retrospectively analyzed...

INTRODUCTION: Fusion of joints as well as intervertebral spaces by the formation of bony spurs appearing as syndesmophytes and osteophytes are the hallmark of spondyloarthropathies which accounts for disability. The aim of this study was to assess the serum level of bone morphogenetic protein (BMP)-7 in ankylosing spondylitis and its relationship with disease activity and the radiographic damage. METHODS: This longitudinal case control study was conducted in Ain Shams University Hospitals (Egypt)...

A boy presented initially to a Rheumatology clinic with a three year history of asymptomatic swelling of the third to fourth proximal interphalangeal (PIP) joints bilaterally. A presumptive diagnosis of seronegative arthritis was made. Sulfasalazine was commenced without improvement and resulted in mood disturbance. Blood tests including ESR, lupus anticoagulant, rheumatoid factor and CCP antibodies were unremarkable. Hand radiographs were normal. MRI showed oedema within soft tissues around PIP joints. His care was transferred to the Rheumatology unit in our hospital and the rheumatological diagnosis was revised; sulfasalazine was stopped and skin biopsy organised...

OBJECTIVE: The differences between seronegative and seropositive rheumatoid arthritis (RA) have not been widely reported. We performed electronic health record (EHR)-based phenome-wide association studies (PheWAS) to identify disease associations in seropositive and seronegative RA. METHODS: A validated algorithm identified RA subjects from the de-identified EHR. Serotypes were determined by values of rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (ACPA)...

BACKGROUND: Progressive pseudorheumatoid dysplasia (PPD) is a rare spondylo-epi-metaphyseal dysplasia (SEMD). It can be confused with juvenile idiopathic arthritis (JIA), both clinically and radiologically. Early detection and diagnosis of PPD are important in helping to relieve the pain and disability associated with this disease and in avoiding unnecessary investigations and anti-rheumatic interventions. CASE DETAILS: We report the case of a 15-year-old girl with PPD who was misdiagnosed with JIA...

Multiple myeloma can rarely mimic seronegative rheumatoid arthritis (RA). We report a 55-year-old woman who presented with longstanding deforming polyarthritis with extensive subcutaneous nodules, tenosynovitis, anti-cyclic citrullinated peptide positivity and mononeuritis multiplex. Even though the clinical picture was consistent with seropositive RA, the absence of bone erosion or joint space narrowing on hand and knee radiographs led us to question the diagnosis of RA. Further investigation revealed a diagnosis of multiple myeloma with cutaneous amyloid deposits, based on serum immunofixation, bone marrow aspiration and biopsy of a subcutaneous nodule...

Radionuclide synovectomy is a minimally invasive method of treating persistent joint inflammation. It involves intra-articular injection of radioactive colloids which induce necrosis and fibrosis of hypertrophic synovial membrane. The most common indication for radiosynovectomy is rheumatoid arthritis, although patients with seronegative spondyloarthropathies, unclassified arthritis, haemophilic arthropathy and other less common arthropathies can also benefit from this method. Radiosynovectomy is safe, well tolerated and efficacious...

The foot and ankle are commonly involved in a range of arthritides that affect the joints, bones, and soft tissues. Accurate plain film interpretation can often aid the diagnosis and monitor disease progression and treatment response. Ultrasound and MRI afford superior depiction of the soft tissues, and advances over recent years have centered on early detection of synovitis, enabling earlier diagnosis and treatment. Advantages and disadvantages of the imaging techniques of radiography, multidetector computed tomography, ultrasound, and MRI are discussed, as is optimization of these modalities for the assessment of the anatomically complex joints of the foot and ankle...

BACKGROUND: Recently, autoantibodies against novel UH-RA peptides (UH-RA.1 and UH-RA.21) were identified as candidate biomarkers for patients with rheumatoid arthritis (RA) who are seronegative for the current diagnostic markers rheumatoid factor and anticitrullinated protein antibodies. Previously, screening for anti-UH-RA autoantibodies was based on measuring the immunoglobulin (Ig) G response. We aimed to investigate whether measurement of other isotypes could improve the performance of diagnostic testing...

BACKGROUND: Seronegative rheumatoid arthritis is associated with a milder course of progression compared to seropositive disease. However, long-term follow-up data of the clinical course of seronegative rheumatoid arthritis are sparse. Here we describe four cases with a rare disease entity of aggressive destructive seronegative (rheumatoid) arthritis with 20-35 years of follow-up. CASE PRESENTATION: The four cases are women with an initial presentation of seronegative rheumatoid arthritis in 1980-1996 and have received disease-modifying anti-rheumatic drugs since the diagnosis...
