The evolution of diagnostic imaging has been recently characterized by a wish for a better understanding of pathogenesis of diseases and by technologic progress. Many authors published papers reexamining old myths and old concepts of osteoarthritis. Correlations between clinical data, radiologic data, and MR findings have allowed better definition of the characteristics of osteoarthritis of the knee. MR imaging is of great value in evaluating rheumatoid arthritis in the early stages and in certain locations such as the cervical spine and temporomandibular joint. New imaging techniques, especially CT and MR imaging, are also useful for accurately diagnosing Andersson lesions and cauda equina syndrome in ankylosing spondylitis as well as sacroiliac joint abnormalities in Crohn's disease.

Aceclofenac is a phenylacetic acid derivative with anti-inflammatory and analgesic properties similar to those of diclofenac. However, preclinical studies suggest that the potential of aceclofenac to cause gastrointestinal damage is less than that of diclofenac. Double-blind comparative trials indicate that the efficacy of aceclofenac is at least equivalent to that of ketoprofen and similar to that of indomethacin and diclofenac in patients with rheumatoid arthritis, similar to that of diclofenac and piroxicam in patients with osteoarthritis of the knee and similar to that of tenoxicam, indomethacin and naproxen in patients with ankylosing spondylitis. The analgesic efficacy of aceclofenac 100mg is more prolonged than that of paracetamol (acetaminophen) 650mg. If the apparently improved gastrointestinal tolerability of aceclofenac compared with diclofenac is confirmed by wider clinical experience, aceclofenac will have the potential to become a preferred initial drug in an individualised NSAID regimen in patients with rheumatic disorders.

Several clinical trials, post-marketing surveillance studies and a meta-analysis were performed to obtain information about dose finding, pharmacokinetics, special indications, tolerability and compliance. In eight clinical trials, according to GCP, 1463 patients were included. Six of the trials were double-blind studies against placebo, racemic ibuprofen and diclofenac; the pharmacokinetic study and a long-term safety study were open studies. A meta-analysis of five clinical trials compared tolerability and safety data between dexibuprofen and racemic ibuprofen. Three PMS studies collected data on 7133 outpatients. All clinical trials and PMS studies have been published. In the dosage ratio 0.5:1, dexibuprofen was found to be at least as efficacious as racemic ibuprofen; 75% of the maximum daily dose of dexibuprofen was equally efficacious as 100% of MDD of diclofenac; no influence was found of meals on bioavailability and a significant doseresponse relationship; there was clinical efficacy in rheumatoid arthritis, ankylosing spondylitis, osteoarthritis of the hip, osteoarthritis of the knee, lumbar vertebral syndrome, distortion of the ankle joint and dysmenorrhoea; there was good tolerability compared to other NSAIDs: racemic ibuprofen showed a 30% and diclofenac a 90% higher incidence of adverse drug reactions; the long-term study stated a 15.2% adverse drug event incidence; the incidence of adverse drug reactions in the PMS studies was between 5.5% and 7.4%, and withdrawals were between 2.3% and 2.7%. In conclusion, dexibuprofen (Seractil) has the stature of a modern NSAID, combining the high efficacy of diclofenac with the good tolerability of ibuprofen, and need not hide behind the new generation of COX-2 inhibitors.

The production of autoantibodies to citrullinated type II collagen and the citrullination of type II collagen were analyzed in rheumatoid arthritis. Autoantibodies to citrullinated type II collagen were detected in 78.5% of serum samples from 130 rheumatoid arthritis patients. Autoantibodies to native noncitrullinated type II collagen were detected in 14.6% of serum samples, all of which were positive for anti-citrullinated type II collagen antibodies. Serum samples were also positive for anti-citrullinated type II collagen antibodies in 1 of 31 systemic lupus erythematosus patients and 2 of 55 patients with osteoarthritis of the knee. In contrast, sera samples from 24 systemic sclerosis patients, 21 dermatomyositis/polymyositis patients, 21 ankylosing spondylitis patients, and 18 psoriatic arthritis patients were all negative for anti-citrullinated type II collagen antibodies. Anti-citrullinated type II collagen antibodies and fragments of citrullinated type II collagen were found in the synovial fluid obtained from affected knee joints of 15 rheumatoid arthritis patients. Moreover, anti-citrullinated type II collagen antibodies were isolated from the synovium of affected knee joints in 8 rheumatoid arthritis patients using antigen/antibody immunocomplex dissociation buffer but not by using standard buffers. These findings indicate that autoantibodies that react with citrullinated type II collagen are specifically produced and that immunocomplexes composed of fragments of citrullinated type II collagen and autoantibodies are deposited in the inflamed articular synovium in rheumatoid arthritis patients. Assaying for the presence of anti-citrullinated type II collagen antibodies may therefore be useful for diagnosing rheumatoid arthritis, and the deposition of these immunocomplexes in the articular synovium may be involved in pathogenesis.

Naproxen/esomeprazole is a fixed-dose combination of the NSAID naproxen and the proton pump inhibitor esomeprazole. In two well designed, 12-week studies, naproxen/esomeprazole fixed-dose combination was noninferior to celecoxib in treating the signs and symptoms of disease in patients with osteoarthritis of the knee, as assessed by the mean change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index pain and function scores and Patient Global Assessment scores (coprimary endpoints). Two other studies showed that the cumulative incidence of gastric ulcers (primary efficacy measure) was significantly lower with naproxen/esomeprazole than with enteric-coated naproxen alone during up to 6 months' therapy in patients with osteoarthritis, rheumatoid arthritis, ankylosing spondylitis or any other condition requiring daily NSAID therapy. The fixed-dose combination was generally well tolerated in these studies, with an upper gastrointestinal tolerability profile generally better than that of naproxen and similar to that of celecoxib.
