Although many epidemiological studies have investigated the association between body mass index (BMI) and risk of rheumatoid (RA), the results have been inconsistent. Therefore, we performed a dose-response meta-analysis to quantify the dose-response association between BMI and RA risk.We systematically searched PubMed, Embase, and Web of Science databases and reference lists of articles for relevant studies published before August 2014 using terms related to BMI and RA. Fixed or random-effects models were used to estimate the pooled relative risk (RR) with 95% confidence interval (CI)...

BACKGROUND: Whipple's disease is a rare, often multisystemic chronic infectious disease caused by the rod-shaped bacterium Tropheryma whipplei. Very rarely the heart is involved in the process of the disease, leading to culture-negative infective endocarditis. Up to 20 % of all infective endocarditis are blood culture-negative and therefore a diagnostic challenge. We present two unusual cases of culture-negative infective endocarditis encountered in two different patients with prior history of arthralgia...

The aim of this study was to investigate treatment response and hepatic safety of anti-tumor necrosis factor-α therapy among patients with concomitant rheumatoid arthritis (RA) and hepatitis C virus (HCV) infection. We reviewed the charts of 101 consecutive RA patients who were eligible for anti-TNF-α therapy in the Chiayi Branch of Chang Gung Memorial Hospital. Group A patients were sero-positive for anti-HCV antibodies and had HCV RNA but were negative for hepatitis B surface antigen (HBsAg). Group B (the control group) patients were sero-negative for both anti-HCV antibodies and HBsAg...

BACKGROUND: It has been suggested that polymorphisms in Toll-like Receptors (TLRs) are associated with Rheumatoid Arthritis (RA), but the implicated alleles have differed between studies. The aim of this investigation was to explore whether polymorphisms of TLR genes are associated with RA in a predominantly Caucasian population from Denmark using a case-control approach. FINDINGS: DNA samples (3 university hospital outpatient clinics) were obtained from patients with RA (n = 704) and healthy controls (n = 639) in a Danish population...

Psoriatic arthritis is a condition that causes inflammation of the joints of psoriatic patients. Psoriatic arthritis also affects tissues surrounding the joints including tendon and ligaments. Psoriatic arthritis (PsA), recognized for over 100 years, is the second most frequent diagnostic category after Rhematoid Arthritis (RA) and occurring up to 10% of patients with skin psoriasis. Although PsA is a sero-negative arthritis and the absence of rheumatoid factor is a characteristic laboratory finding, it may be present in 3% of psoriatic arthritis (PsA) patients...

The authors present the case of a 53-year-old female, initially admitted in a rheumatology department for fever and diffuse arthritis--being diagnosed with sero-positive rheumathoid arthritis. Although the chest X-ray and CT scan of thorax showed several abnormal features (medium lobe atelectasis, pseudo-cyst in the posterior segment of the right upper lobe with satellite milliary nodules, mediastinal lymph node enlargement), the investigations performed in our pneumology department couldn't establish the etiology of radiological abnormalities...

Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis (RA), diagnosed with negative rheumatoid factor (RF) tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis. The aim of the study was to establish a scientific comparative analysis between RA seronegative and seropositive, regarding course and prognoses of the disease. Two hundred fifty patients with rheumatoid arthritis according to the (American College of Rheumatology) criteria were retrospectively studied by analysis the course and prognoses of disease...

SESSION TYPE: Miscellaneous Case Report Posters IIPRESENTED ON: Tuesday, October 23, 2012 at 01:30 PM - 02:30 PMINTRODUCTION: Lung disease occurs commonly in rheumatoid arthritis (RA) and is associated with significant morbidity and mortality. Recently, Fischer and colleagues demonstrated that anti-cyclic citrullinated peptide (anti-CCP) positive individuals with airways or interstitial lung disease may represent a "pre-articular" RA phenotype.CASE PRESENTATION: A 61-year-old Caucasian man, with a 7.5 pack-year smoking history, seasonal allergies, gastroesophageal reflux disease, obstructive sleep apnea, and dyslipidemia presented with pleuritic chest pain and dry cough of five months duration...

Our aim was to elucidate the relative amount of the different splice forms of FoxP3 mRNA in CD4+ T cells in peripheral blood (PB) compared to synovial fluid (SF) in RA and PsA patients. FoxP3 mRNA was measured using a quantitative real-time PCR method. CD4+ T cells were isolated from 17 paired samples of PB and SF from RA and PsA patients, and PB from 10 controls. FoxP3fl and FoxP3Δ2 mRNA was significantly increased (6.7 and 2.1-fold, respectively) in PB CD4+ T cells from RA patients compared to controls. FoxP3fl and Δ2 mRNA in SF CD4+ T cells was increased compared to controls in sero-negative RA and PsA, but not in sero-positive RA patients, who had a high FoxP3 expression in both PB and SF...

Although the HLA region contributes to one-third of the genetic factors affecting rheumatoid arthritis (RA), there are few reports on the association of the disease with any of the HLA loci other than the DRB1. In this study we examined the association between RA and the alleles of the six classical HLA loci including DRB1. Six HLA loci (HLA-A, -B, -C, -DRB1, -DQB1 and -DPB1) of 1659 Japanese subjects (622 cases; 488 anti-cyclic citrullinated peptides (CCP) antibody (Ab) positive (82.6%); 103 anti-CCP Ab negative (17...

To investigate the similarities and differences in clinical features between the sero-negative and sero-positive rheumatoid arthritis (RA) patients. Two hundred and sixty-two RA patients who fulfilled the 1987 ACR RA Classification Criteria were enrolled into this study. They were divided into sero-negative and sero-positive group depending on the presence or absence of rheumatoid factor (RF) and anti-cyclic citrullinate peptide (anti-CCP). The clinical features were compared between these two groups. Forty-six (17...

Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis, diagnosed with negative rheumatoid factor tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis (RA). Our aim was to establish a scientific comparative analysis between seronegative and seropositive rheumatoid arthritis, regarding some radiological and clinical parameters, applied for the first time on patients from Kosovo. Two hundred fifty patients with rheumatoid arthritis according to the American College of Rheumatology criteria were retrospectively studied by analysis the radiographic damage and clinical parameters of the disease, using a data base...

Treatment with tumour necrosis factor-alpha inhibitors increases the risk of tuberculosis (TB). Screening for latent TB infection (LTBI) and prophylactic treatment has become mandatory. A 79-yr-old female with a history of severe erosive sero-positive rheumatoid arthritis was screened for LTBI before initiation of treatment with infliximab. The tuberculin skin test (TST) was negative, chest radiography was normal and she had no known risk factors for TB. After 4 months of treatment with infliximab, the patient developed ascites caused by Mycobacterium bovis...

Early diagnosis of rheumatoid arthritis (RA) is a challenge due to an insufficient specificity of its clinical signs and a low sensitivity of presently used clinico-laboratory criteria. Cyclic citrullinated peptide antibodies (CCPA) are nowadays considered the most promising diagnostic and prognostic RA marker. A heterogeneous group of citrullinated peptides are the target for CCPA. The sensitivity of CCPA is comparable to that of the rheumatoid factor (RF), while its specificity for this disease is much higher...

Two cases of leflunomide-induced peripheral neuropathy are described; in a 60-year-old woman with sero-negative polyarthralgia-myalgia syndrome and a 65-year-old man with sero-negative rheumatoid arthritis, both treated with leflunomide at 20mg/day. Nerve conduction studies and electromyogram showed sensorimotor axonal neuropathy in both cases. An alternative cause for the axonal neuropathy was excluded by extensive investigations, including cerebrospinal fluid examination and nerve biopsy in the second patient...

Five to 7% of patients with cutaneous psoriasis suffer from inflammatory rheumatism that is sero-negative for rheumatoid factor, and is often erosive. The inflammation is predominant to the entheses and can affect the axial or peripheral skeleton, often in an associated manner. The most common peripheral signs are those of an asymmetrical oligo-arthritis type, and the most evocative are arthritis of the distal inter-phalangeal joints. A symmetrical polyarthritis can also be observed. The severe mutilating forms are fortunately very rare...
