Human T cell leukemia virus type I (HTLV-I) env-pX transgenic rats (env-pX rats) develop chronic destructive arthritis resembling rheumatoid arthritis in humans. Immunological characteristics were compared with those of collagen-induced arthritis (CIA). Rheumatoid factor was present in some env-pX rats regardless of the development of arthritis, but not in nontransgenic rats with CIA. All rats with CIA produced anti-type II collagen (IIC) antibody, but never so in env-pX rats with naturally occurring arthritis. Although expansions of oligoclonal T cells were evident in the affected joints, no particular clone was shown to infiltrate into the arthritic lesions in env-pX rats. In contrast to CIA, in which clonal expansions of IIC-specific T cells are implicated, locally expanded T cell clones against various antigens of the joints may play pathogenetic roles in the arthritis seen in env-pX rats. However, complementarity-determining region 3 of the TCR Vbeta gene of T cells accumulating at the affected joints in env-pX rats contained the GGA amino acid sequence, which was reported to be a conserved motif in HTLV-I env-pX transgenic mice with arthritis. These findings suggest that common antigen(s) might be recognized by T cells accumulating at sites of arthritis in both transgenic rats and mice.

Advanced glycation end-product (AGE)-damaged IgG occurs as a result of hyperglycemia and/or oxidative stress. Autoantibodies to IgG-AGE were previously demonstrated in patients with severe, longstanding rheumatoid arthritis (RA). We investigated whether IgG-AGE and anti-IgG-AGE antibodies were present early in the course of RA and other inflammatory arthropathies. We prospectively followed a cohort of 238 patients with inflammatory arthritis of duration less than 1 year. Patients were evaluated clinically and serologically, and radiographs were obtained at initial and 1-year visits. Sera were assayed for IgG-AGE and anti-IgG-AGE antibodies by enzyme-linked immunosorbent assay (ELISA). Rheumatoid factor (RF) was determined by nephelometry and ELISA. Of all patients, 29% had RF-positive RA, 15% had RF-negative RA, 18% had spondyloarthropathy, and 38% had undifferentiated arthritis. IgG-AGE was present in 19% of patients, and was similar in amount and frequency in all groups. Patients with elevated IgG-AGE levels had significantly higher levels of the inflammatory markers C-reactive protein and erythrocyte sedimentation rate, but there was no correlation with blood glucose levels. Overall, 27% of the patients had IgM anti-IgG-AGE antibodies. These antibodies were highly significantly associated with RFs (P < 0.0001) and with swollen joint count (P < 0.01). In early onset arthritis, IgG damaged by AGE was detected in all patient groups. The ability to make IgM anti-IgG-AGE antibodies, however, was restricted to a subset of RF-positive RA patients with more active disease. The persistence of the anti-IgG-AGE response was more specific to RA, and was transient in the patients with spondyloarthropathy and with undifferentiated arthritis who were initially found to be positive for anti-IgG-AGE antibodies.

Although bone and joint manifestations are common in children with cystic fibrosis (CF), they have received little attention in adults. As compared to healthy individuals, bone mineral density is low, even with calcium intakes greater than 1500 mg/d. Nevertheless, calcium and phosphate levels in blood and urine are often normal, and vitamin D levels vary. Short stature with a low body mass index and central hypogonadism are the rule in these patients. Fractures and kyphosis are often reported. CF arthropathy occurs in 2-8.5% of patients. Arthritis develops, and there may be skin eruptions. Non-steroidal antiinflammatory drug therapy is effective. Hypertrophic osteoarthropathy associated with respiratory failure is present in 2-7% of patients. Rheumatoid arthritis, spondyloarthropathies, sarcoidosis, and amyloidosis have been reported in association with CF. Knee pain due to patellofemoral syndrome, quinolone-induced arthropathy, and mechanical back pain have been described. Rheumatoid factor titers are higher than in healthy controls, particularly in patients with episodic arthritis. No data are available on antiperinuclear factor or antikeratin antibody titers. Tests for antinuclear antibody are usually negative. Circulating immune complex levels and antibodies to heat shock proteins may be elevated. Antineutrophil cytoplasmic antibody of the bactericidal/permeability-increasing protein (BPI) or azurocidin (AZ) type has been reported, often in high titers (up to 40%).

A 78-year-old man who was undergoing hemodialysis therapy was admitted to our hospital because of sore throat, remittent cervical lymphadenopathy, and polyarthritis over the preceding 4 weeks. On admission, he had bilateral cervical lymphadenopathy. He complained of arthralgia associated with tenderness, warmth and swelling of both elbows, left side wrist and left shoulder joint. The C-reactive protein level on admission was 15.3 mg/dl. Rheumatoid factor, antinuclear antibodies, tuberculin skin test and blood culture were negative. Joint fluid was not aspirated. Radiographs of the joints did not reveal any abnormalities. Acid-fast bacilli were demonstrated in the smear of the cervical lymph node with a fluorochrome rhodamine-auramine stain. Mycobacterium tuberculosis DNA was identified by polymerase chain reaction. We found the presence of caseating granuloma on the biopsy specimens and M.tuberculosis was detected from culture. At that point, we diagnosed this patient as having tuberculous lymphadenitis. His general symptoms resolved rapidly after starting with a three-drug regimen consisting of isoniazid, rifampin and pyrazinamide. His polyarthritis also improved dramatically. Finally we considered that his polyarthritis was tuberculous rheumatism, also called Poncet's disease. Poncet's disease is characterized by sterile polyarthritis during active tuberculosis infection. It is considered a reactive arthritis, which is a different entity from tuberculous arthritis. Although this is a rare disease, we should be aware of it in hemodialysis patient clinics, because the incidence of tuberculosis infection has been reported to be increasing in patients with end-stage renal failure.

Rheumatoid arthritis is a common disease that is now known to progress to irreversible erosive changes in the joints much more quickly than previously recognized. Physicians thus need to identify the early symptoms and signs to make a prompt clinical diagnosis and then start earlier aggressive treatment. Critical features are morning stiffness and symmetrical inflammation involving usually small joints of the hands and feet. Soft tissue swelling is the most important sign of inflammation and begins most often at the metacarpal phalangeal or proximal interphalangeal joints. Joints are tender and warm but often not hot and red. Elevation of erythrocyte sedimentation rate can help confirm the presence of inflammation but the most important laboratory test is synovial fluid analysis which further confirms inflammation but can also help exclude many of the other potentially confusing causes of arthritis. Rheumatoid factor is present in 75% of patients but can also be seen with some other diseases.

Predicting which patients will develop severe rheumatoid arthritis is essential for selection of the most appropriate treatment regimen in early arthritis. The key outcomes in rheumatoid arthritis are persistence of the disease, joint damage (evaluated by X-ray progression), functional disability, and mortality rate. Rheumatoid factor positivity and number of swollen joints appear to be related to all of these outcomes, while radiologic scores are mostly related to joint damage and health assessment questionnaire (HAQ) to functional disability. Other relevant prognostic parameters are erythrocyte sedimentation rate or serum C-reactive protein levels, and antibodies to citrullinated peptides.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that affects symmetrically multiple joints. Recent therapeutic strategy has been focusing on the symptoms of the disease and the ways to prevent its progression as early as possible. Thus, early diagnosis is crucial since early therapy with disease-modifying anti-rheumatic drugs reduces the severity of joint damage. It is the early period of the development of the disease that a specific and sensitive serologic test is needed. The RA patient sera contains a lot of antibodies. Some of them are not specific for RA occurring also in other diseases, others are highly specific and detectable only in rheumatoid arthritis. Rheumatoid factor (RF) is a very sensitive but poorly specific marker which makes it rather an unsuitable antibody for rheumatoid arthritis. RA-specific antibodies can be very useful for early diagnosis and prognosis of the disease. Among the antibodies described in recent years the most promising candidates are the autoantibodies to antigens containing one or more than one citrulline residues (cyclic citrulline peptides, CCP) - the anti-CCP antibodies. They have been shown in recent research to play an important role in the diagnosis, prognosis and therapeutic approach to patients with RA. Their high specificity, the ability to diagnose RA early in its development and distinguish it from other nonerosive type of arthritis, make the anti-CCP a key serologic marker in the future.

A 53-year-old man presented with firm, non-tender subcutaneous nodules overlying his hands and elbows. These had been progressive in number and size over 7 years. Rheumatoid factor was negative but a biopsy was consistent with rheumatoid nodules. He has never had any joint symptoms and remains otherwise asymptomatic. Examination is unremarkable except for the nodules described. We believe this man has rheumatoid nodules with no evidence of arthritis.

The aim of this study was to evaluate the prevalence of rheumatoid arthritis (RA) in Antalya, Turkey. A cross-sectional study was performed face-to-face using a structured interview. Subjects were asked whether they had arthritis at present or previously. Subjects suspected of having RA were invited to the hospital for physical examination and laboratory investigations. Diagnosis of RA was confirmed if the patient fulfilled 1987 American College of Rheumatology (ACR) criteria for RA. A total of 3173 subjects were interviewed. The diagnosis of RA was established in 12 subjects. The prevalence of RA was determined as 0.38% [95% confidence interval (CI): 0.16-0.59]. The mean age was 49.92+/-11.56 years in subjects with RA and greater than that of other subjects (p<0.001). Of 12 subjects with RA, 9 had previously been diagnosed with the disease. Rheumatoid factor was detected in the sera of eight subjects. RA is less frequent in Turkey than in Northern Europe. Different genetic and environmental factors may have a role in this result.

Pathological processes involved in the initiation of rheumatoid synovitis remain unclear. We undertook the present study to identify immune and stromal processes that are present soon after the clinical onset of rheumatoid arthritis (RA) by assessing a panel of T cell, macrophage, and stromal cell related cytokines and chemokines in the synovial fluid of patients with early synovitis. Synovial fluid was aspirated from inflamed joints of patients with inflammatory arthritis of duration 3 months or less, whose outcomes were subsequently determined by follow up. For comparison, synovial fluid was aspirated from patients with acute crystal arthritis, established RA and osteoarthritis. Rheumatoid factor activity was blocked in the synovial fluid samples, and a panel of 23 cytokines and chemokines measured using a multiplex based system. Patients with early inflammatory arthritis who subsequently developed RA had a distinct but transient synovial fluid cytokine profile. The levels of a range of T cell, macrophage and stromal cell related cytokines (e.g. IL-2, IL-4, IL-13, IL-17, IL-15, basic fibroblast growth factor and epidermal growth factor) were significantly elevated in these patients within 3 months after symptom onset, as compared with early arthritis patients who did not develop RA. In addition, this profile was no longer present in established RA. In contrast, patients with non-rheumatoid persistent synovitis exhibited elevated levels of interferon-gamma at initiation. Early synovitis destined to develop into RA is thus characterized by a distinct and transient synovial fluid cytokine profile. The cytokines present in the early rheumatoid lesion suggest that this response is likely to influence the microenvironment required for persistent RA.
