Anti-CCP and antikeratin antibodies in rheumatoid arthritis, primary Sjögren's syndrome, and Wegener's granulomatosis.

The objective of this study was to investigate the frequency of antibodies against cyclic citrullinated peptides (anti-CCP) and keratin (AKA) in patients with rheumatoid arthritis (RA) as well as in patients with primary Sjögren's syndrome (pSS) and Wegener's granulomatosis (WG), who may present with rheumatoid factor (RF)-positive arthritis. The study group consisted of 46 patients with RA (26 patients were negative for RF), 32 with pSS, 22 with WG, and 40 healthy controls. The RF, anti-CCP, and AKA were detected in serum using the latex agglutination test, enzyme-linked immunosorbent assay, and indirect immunofluorescence, respectively. The agreement between those tests was evaluated by kappa test. No positive result for AKA was detected in pSS and WG patients, and anti-CCP was found in only one patient with pSS. The results of kappa tests were low, varying between 0.25 (RF-anti-CCP) and 0.02 (RF-AKA). The sensitivity and specificity values were 43 and 44% for RF, 65 and 98% for anti-CCP, and 58 and 100% for AKA, respectively, in RA patients. In the RF-negative RA group, AKA was found to have a high frequency (55%) in comparison to anti-CCP (38%). Seropositivity was found to be 87% for any one of the three autoantibodies tested in RA patients. With a higher specificity, values for RA, anti-CCP, and AKA seem to be helpful for the differential diagnosis of patients with RF-positive arthritis, which may include patients with WG and pSS, and screening of all three antibodies may increase the diagnostic performance.

Efficacy of infliximab in the treatment of uveitis that is resistant to treatment with the combination of azathioprine, cyclosporine, and corticosteroids in Behçet's disease: an open-label trial.

OBJECTIVE: To investigate the effect of infliximab on the frequency of uveitis attacks and the visual prognosis in male patients with Behçet's disease in whom uveitis was resistant to combination therapy with corticosteroids, azathioprine, and cyclosporine. METHODS: The study group comprised patients who were receiving combination therapy but experienced at least 2 attacks of posterior uveitis/panuveitis or retinal vasculitis during the 6-month period prior to enrollment. Infliximab infusions (5 mg/kg) were administered at weeks 0, 2, 6, and 14. Weeks 0-22 were defined as the infusion period, and weeks 23-54 were defined as the observation period. Patients continued to receive azathioprine and corticosteroids, but cyclosporine was discontinued after the screening visit. The primary outcome measures were the absence of uveitis attacks during the infusion period (remission), and the absence of uveitis attacks throughout the study period (sustained remission). RESULTS: Thirteen patients were enrolled in the study. Thirty-two uveitis attacks involving the posterior segment occurred during the previous-treatment period. During the infusion period, 4 patients (30.8%) remained attack-free, and 9 patients had a total of 13 uveitis attacks. Ten of these attacks (76.9%) occurred at either week 14 or week 22. One of 13 patients fulfilled the definition of sustained remission, and the remaining 12 patients had a total of 36 uveitis attacks during the observation period. The mean number of uveitis attacks and daily corticosteroid doses were significantly lower during the infusion period than during the previous-treatment period or the observation period. Although potential visual acuity was regained following infliximab infusion, this beneficial effect was not preserved until week 54. None of the patients experienced a serious adverse event. CONCLUSION: The results of this trial suggest that infliximab is effective in suppressing the occurrence of uveitis attacks, has a corticosteroid-sparing effect, and has favorable implications for the visual prognosis of patients with resistant Behçet's uveitis.

HLA B-27 subtypes in Turkish patients with spondyloarthropathy and healthy controls.

The frequency and the distribution of HLA-B27 subtypes in spondylarthropathy (SpA) patients and controls were investigated in a sample Turkish population. B27 subtyping was performed by PCR-SSP method in two groups: 49 unrelated HLA-B27 positive Turkish patients with the diagnosis of SpA according to the European Spondyloarthropathy Study Group Criteria, and 55 HLA-B27 positive healthy controls. The frequency of HLA-B*27 was 2.6% in the Turkish population, and B*2705 was the predominant allele among patients with SpA. The difference was mainly between male patients and male controls The proportion of B*2705 among B27-positive patients and controls was significantly different (P=0.02). Our study supports other reports from different populations which showed that B*2705 and B*2702 were more frequent in Caucasian patients with SpA.
