Objective: To compare the efficacy, pharmacokinetics and safety of etanercept 50 mg once weekly with 25 mg twice weekly and placebo in patients with ankylosing spondylitis. Methods: A 12-week, double-blind, placebo-controlled study compared the effects of etanercept 50 mg once weekly, etanercept 25 mg twice weekly and placebo in 356 patients with active ankylosing spondylitis (3:3:1 randomisation, respectively). The primary end point was the proportion of patients achieving a response at week 12 based on the Assessment in Ankylosing Spondylitis Working Group criteria (ASAS 20). The pharmacokinetics of etanercept 50 mg once weekly and 25 mg twice weekly were analysed. Results: Baseline characteristics and disease activity were similar among the three groups: etanercept 50 mg once weekly, etanercept 25 mg twice weekly and placebo. The percentage of patients discontinuing therapy was 9.0%, 9.3% and 13.7% for the three respective groups. ASAS 20 response at 12 weeks was achieved by 74.2% of patients with etanercept 50 mg once weekly and 71.3% of those with etanercept 25 mg twice weekly, both significantly higher than the percentage of patients taking placebo (37.3%, p<0.001). Percentages of patients with ASAS 5/6 response (70.3%, 72.0% and 27.5%, respectively; p<0.001) and those with ASAS 40 response (58.1%, 53.3% and 21.6%, respectively; p<0.001) followed a similar pattern. Significant improvement (p<0.05) was seen in measures of disease activity, back pain, morning stiffness and C reactive protein levels as early as 2 weeks. Serum etanercept exposure was similar between the etanercept groups. Incidence of treatment-emergent adverse events, including infections, was similar among all three groups, and no unexpected safety issues were identified. Conclusions: Patients with ankylosing spondylitis can expect a comparable significant improvement in clinical outcomes with similar safety when treated with etanercept 50 mg once weekly or with 25 mg twice weekly.

Objective To assess the efficacy and safety of low-dose prednisone chronotherapy using a new modified-release (MR) formulation for the treatment of rheumatoid arthritis (RA). Methods In this 12-week, double-blind, placebo-controlled study, patients with active RA (n=350) were randomised 2:1 to receive MR prednisone 5 mg or placebo once daily in the evening in addition to their existing RA disease-modifying antirheumatic drug (DMARD) treatment. The primary end point was the percentage of patients achieving a 20% improvement in RA signs and symptoms according to American College of Rheumatology criteria (ie, an ACR20 response) at week 12. Changes in morning pain, duration of morning stiffness, 28-joint Disease Activity Score and health-related quality of life were also assessed. Results MR prednisone plus DMARD treatment produced higher response rates for ACR20 (48% vs 29%, p<0.001) and ACR50 (22% vs 10%, p<0.006) and a greater median relative reduction from baseline in morning stiffness (55% vs 35%, p<0.002) at week 12 than placebo plus DMARD treatment. Significantly greater reductions in severity of RA (Disease Activity Score 28) (p<0.001) and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue score) (p=0.003) as well as a greater improvement in physical function (36-item Short-Form Health Survey score) (p<0.001) were seen at week 12 for MR prednisone versus placebo. The incidence of adverse events was similar for MR prednisone (43%) and placebo (49%). Conclusion Low-dose MR prednisone added to existing DMARD treatment produced rapid and relevant improvements in RA signs and symptoms. ClinicalTrials.gov, number NCT00650078

Objective This 9-month open-label extension of the Circadian Administration of Prednisone in Rheumatoid Arthritis Study (CAPRA 1) investigated the long-term safety and efficacy of prednisone chronotherapy with a novel modified-release (MR) prednisone for up to 12 months. Methods Of 288 patients with rheumatoid arthritis originally randomised to MR or immediate-release (IR) prednisone, 249 continued with prednisone chronotherapy (2–10 mg/day) in the 9-month open-label extension. Duration of morning stiffness of the joints (MS), disease activity scores (DAS28), American College of Rheumatology (ACR20) responses and plasma levels of interleukin 6 (IL-6) were assessed. Safety was analysed from adverse event reports and laboratory investigations. Results During the 3-month double-blind phase, patients in the MR group achieved a reduction in MS of 33.1% while no change was observed in the IR group. After 6 months of treatment, MS was reduced in the IR/MR group by 54% and in the MR/MR group by 56%. MS reduction after 12 months was 45% (IR/MR group) and 55% (MR/MR group). Plasma levels of IL-6 declined on MR treatment. DAS28 was reduced from 5.8 to 4.8 (MR/MR group) and 4.9 (IR/MR group), respectively. 37% of the 219 patients who completed the 12-month study achieved improvement according to the ACR20 criteria. Adverse events did not differ from the known profile of low-dose prednisone. Conclusions Prednisone chronotherapy with the MR tablet was safe and well tolerated and provided a sustained improvement which resulted in a better benefit to risk ratio of low-dose glucocorticoid treatment for at least 12 months.

It is well documented that serum IgG from rheumatoid arthritis (RA) patients exhibits decreased galactosylation of its conservative N-glycans (Asn-297) in CH2 domains of the heavy chains; it has been shown that this agalactosylation is proportional to disease severity. In the present investigation we analyzed galactosylation of IgG derived from the patients using a modified ELISA-plate test, biosensor BIAcore and total sugar analysis (GC-MS). For ELISA and BIAcore the binding of IgG preparations, purified from the patients’ sera, to two lectins: Ricinus communis (RCA-I) and Griffoniasimplicifolia (GSL-II) was applied. Based on ELISA-plate test an agalactosylation factor (AF, a relative ratio of GSL-II/RCA-I binding) was calculated, which was proportional to actual disease severity. Repeated testing of several patients before and after treatment with methotrexate (MTX) alone or in combination with Remicade (a chimeric antibody anti-TNF-α) supplied results indicating an increase of IgG galactosylation during the treatment. This introductory observation suggests that IgG galactosylation may be an additional indicator of the RA patients’ improvement.

Perna canaliculus Lipid Complex PCSO-524™ Demonstrated Pain Relief for Osteoarthritis Patients Benchmarked against Fish Oil, a Randomized Trial, without Placebo Control

Marek Zawadzki; Claudia Janosch; Jacek Szechiński

Osteoarthritis (OA) typically generates pain, reduced mobility and reduced quality of life. Most conventional treatments for osteoarthritis, such as non-steroidal anti-inflammatory drugs (NSAIDs) and simple analgesics, have side effects. PCSO-524™, a non polar lipid extract from the New Zealand Green Lipped Mussel, is rich in omega-3 fatty acids and has been shown to reduce inflammation in both animal studies and patient trials. This OA trial examined pain relief changes in relation to quality of life and safety of use for OA patients who took PCSO-524™ compared with patients who took fish oil (containing an industry standard EPA-18% and DHA-12% blend). PCSO-524™ patients showed a statistically significant improvement compared with patients who took fish oil. There was an 89% decrease in their pain symptoms and 91% reported an improved quality of life. Patients treated with fish oil showed significantly less improvement and a greater level of physical discomfort during the study. These results suggest that PCSO-524™ might offer a potential alternative complementary therapy with no side effects for OA patients.

The expressions of terminal sugars in synovial and plasma fibronectins were studied in relation to rheumatoid arthritis (RA) progression defined according to the early, established and late radiological changes in the patients’ hands. The relative amounts of sialic acid and fucose were analyzed by lectin-ELISA using appropriate sialic acid-linked α2-3 (Maackia amurensis) and α2-6 (Sambucus nigra) lectins as well as fucose-linked α1-6 (Aleuria aurantia), α1-2 (Ulex europaeus), and α1-3 (Tetragonolobus purpureus). In the early RA group, the synovial fibronectin reactivities were the lowest with the all lectins used. In the established and late groups, relative sialylation and fucosylation significantly increased. However, sialylation negligibly decreased, whereas fucosylation remained at nearly the same level in the late group. Moreover, the expression of α1-6-linked fucose was found to be related to disease activity. In contrast, plasma fibronectin reactivity with lectins showed different dynamic alterations. In the early RA group, the reactivity of fibronectin with the lectins used was similar to that of healthy individuals, whereas it increased significantly in the established RA group compared with the early and normal plasma groups. In the late RA group it decreased to a level similar to that of the normal group. The lower expressions of terminal sugars in synovial fibronectin were mainly associated with the early degenerative processes of RA. In conclusion, such alterations may be applicable as a stage-specific marker for diagnosis and therapy of RA patients. The higher expression of terminal sugars in fibronectin could be associated with repair and adaptation processes in longstanding disease.

OBJECTIVES To obtain information on the profile of patients with ankylosing spondylitis (AS), disease activity, previous and current treatments, and the proportion and profile of patients treated with conventional medications but considered eligible for anti-tumour necrosis factor (TNF) therapy. METHODS Participants were rheumatologists from seven Central and Eastern European countries who were considered experts in the treatment of AS and were to include 3-5 patients who had never received anti-TNF therapy. Rheumatologists were asked to decide whether they considered their patients candidates for anti-TNF therapy. RESULTS A total of 1506 patients were analysed. Overall, 61% of AS patients who had never received anti-TNF therapy until the time of the survey were considered candidates for anti-TNF therapy based on the clinical judgement of their rheumatologists. This proportion ranged from 40% in Slovakia to 84% in Romania. Candidates had higher levels of disease activity and functional impairment, and they were more likely to report a lower quality of life. Only 38% of candidates fulfilled the Assessment in Ankylosing Spondylitis (ASAS) recommendations with respect to a Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) of at least 4 combined with previous use of at least two non-steroidal anti-inflammatory drugs, ranging from 18% in Poland to 57% in Hungary. CONCLUSION More than half of AS patients currently treated with other medications may be eligible for anti-TNF therapy. Also, rheumatologists regarded disease activity as the determining factor for starting anti-TNF drugs, but their decision did not always fully comply with the ASAS recommendations, confirming the need for continued exchange among the medical community to increase awareness of the ASAS recommendations.
