 Background: The presence of anti-citrullinated peptide/protein antibody (ACPA) has a high specificity and predictive value for the development of rheumatoid arthritis (RA). Some studies have shown decreased titers of this antibody after treatment with infliximab.

Objectives: To assess the changes in ACPA titers in patients with RA after treatment with infliximab as a first biological agent, and to correlate these variations with non-infusion-related adverse effects.

Methods: In a prospective multicenter observational study involving 48 research centers, we assessed 139 patients with established moderate-to-severe RA diagnosed according to American College of Rheumatology criteria. Samples were collected before and 6–12 months after treatment.

Results: The mean age of the study patients was 50.6 years old, and 118 were female (84.9%). Statistically significant variations in ACPA titers were noted in 47 patients (before and after treatment) (P = 0.012). Overall, ACPA titers were decreased in 32 (65.3%) and increased in 15 (34.7%). No correlation was found between severe or mild adverse effects in patients presenting variations in ACPA titers.

Conclusions: The present study showed that infliximab affected ACPA titers, promoting mainly a decrease; however, this was not related to the occurrence of non-infusion-related adverse effects.

 Background: Tight control of disease activity is the recommended target of therapy for rheumatoid arthritis (RA).

Objectives: To determine the outcome of RA with respect to disease activity and the rate of remission, as measured by the DAS-28, in a real-world inception cohort.

Methods: We conducted an observational cross-sectional study of a single-center real-world inception cohort of 101 consecutive patients being treated for RA in 2009–2010 in a rheumatology outpatient clinic. Patients were managed at the discretion of the attending rheumatologist with the goal of achieving remission. DAS-28 scores were calculated and analyzed by clinical and treatment variables derived from the medical files.

Results: Mean patient age was 58.6 ± 13.4 years and mean duration of disease 10.7 ± 7.9 years. Disease remission (DAS-28 < 2.6) was achieved in 26.7% of patients and low disease activity (> 2 .6 DAS-28 < 3.2) in 17%. Monotherapy with a conventional disease-modifying anti-rheumatic drug (C-DMARD, 21% of patients at last follow-up) was associated with a significantly lower mean DAS-28 score and C-reactive protein level than combined C-DMARD treatment (79% of patients), and with shorter disease duration than combined treatment with C-DMARDs or C-DMARD(s)+biological DMARD (40% of patients). Rheumatoid factor and anti-cyclic citrullinated peptide positivity had no effect on DAS-28 scores. Time from diagnosis was inversely correlated with DAS-28 scores.

Conclusions: The achievement of low disease activity and remission in a significant portion of our inception cohort of patients with RA suggests that the treat-to-target strategy is feasible and effective in routine clinical practice.

 Anti-citrullinated peptide antibodies (ACPA) are detected in the sera of rheumatoid arthritis (RA) patients and have a profound role in diagnosis of the disease. In this review we discuss the different cohorts of RA patients in whom the presence, sensitivity and specificity of ACPA were evaluated. The significance of ACPA in the pathogenesis and prognosis RA is also interpreted. Recent advances in the understanding of molecular pathways involved in the pathogenesis of RA have led to the identification of novel biologic agents that are now widely used in patients with RA

 Osteoarthritis of the knee is a common joint disease that can cause substantial pain and disability. The manifestation of pain, however, is highly variable with a poor correlation to plain radiographs. The source of pain in gonarthrosis is elusive. Pain receptors have been found in the synovium, ligaments, capsule, subchondral bone and surrounding tissues with the exception of articular cartilage. The perception of pain is regulated at the spinal and cortical level and is often influenced by psychosocial conditions. There is no definitive treatment modality to relieve the pain and surgery does not necessarily guarantee improvement. Understanding and careful clinical assessment of the sore osteoarthritic knee together with better imaging such as magnetic resonance may improve treatment strategies.

Background: Intraarticular injections for the local treatment of osteoarthritis are widely used in the office or hospital setting. Septic arthritis is a potential catastrophic complication of intraarticular injection, as bacterial arthritis of any cause is associated with up to 15% mortality and residual impairment of joint function in up to 50% of survivors. There is lack of evidence regarding the precautions that should be taken to avoid such a complication, as well as how often it is encountered.

Objectives: To report our experience with the clinical presentation, diagnosis and treatment of knee septic arthritis following intraarticular injections. 

Methods: We followed six patients who were admitted to the hospital and underwent surgery for the treatment of pyogenic arthritis following injection to the knee joint in outpatient clinics.

Results: All but one patient were over 70 years old with comorbidities. Three patients were injected with steroid preparations and three with hyaluronic acid several days before admission. In all six patients the infection was treated surgically and three of them had undergone more than one operation during their hospitalization. Four of the six patients were treated by means of an open arthrotomy and synovectomy, and the other two were treated successfully with arthroscopic lavage and synovectomy. One patient underwent an above-knee amputation due to septic shock and died after several days.

Conclusions: Despite the rarity of this complication, surgeons must be aware of the possibility of pyogenic arthritis when administering injections, especially in elderly patients with serious underlying medical conditions.

 Background:  Pomegranate extract (POMx) consumption has been shown to reduce the incidence and severity of collagen-induced arthritis in mice.

Objectives:  To investigate whether pomegranate consumption affects disease activity in patients with rheumatoid arthritis (RA), in relation to their serum oxidative status.

Methods:  In this pilot 12 week open-labeled study eight patients with active RA consumed POMx (10 ml/day) for 12 weeks. Patients’ joint status and serum oxidative status (lipid peroxidation, total thiols group, paraoxonase 1 activity) were evaluated at baseline and at week 12.

Results:  Six patients completed the study. POMx consumption significantly (P < 0.02) reduced the composite Disease Activity Index (DAS28) by 17%, which could be related mostly to a significant (P < 0.005) reduction in the tender joint count (by 62%). These results were associated with a significant (P < 0.02) reduction in serum oxidative status and a moderate but significant (P < 0.02) increase in serum high density lipoprotein-associated paraoxonase 1 (PON1) activity. The addition of POMx to serum from RA patients reduced free radical-induced lipid peroxidation by up to 25%.

Conclusions:  The pomegranate consumption reduced DAS28 in RA patients, and this effect could be related to the antioxidative property of pomegranates. Dietary supplementation with pomegranates may be a useful complementary strategy to attenuate clinical symptoms in RA patients.

Background: Increased cardiovascular morbidity has become a leading cause of mortality in rheumatoid arthritis (RA). Tumor necrosis factor-alpha (TNFα) inhibitors may influence flow-mediated vasodilation (FMD) of the brachial artery, common carotid intima-media thickness (ccIMT) and arterial stiffness indicated by pulse-wave velocity (PWV) in RA.

Objectives: To assess the effects of adalimumab treatment on FMD[1], ccIMT[2] and PWV[3] in early RA[4].

Methods: Eight RA patients with a disease duration ≤ 1 year received 40 mg adalimumab subcutaneously every 2 weeks. Ultrasound was used to assess brachial FMD and ccIMT. PWV was determined by arteriograph. These parameters were correlated with C-reacive protein, vonWillebrand factor (vWF), immunoglobulin M (IgM)-rheumatoid factor (RF), anti-CCP levels and 28-joint Disease Activity Score (DAS28).

Results: Adalimumab therapy successfully ameliorated arthritis as it decreased CRP[5] levels (P = 0.04) and DAS28[6] (P < 0.0001). Endothelial function (FMD) improved in comparison to baseline (P < 0.05). ccIMT decreased after 24 weeks, indicating a mean 11.9% significant improvement (P = 0.002). Adalimumab relieved arterial stiffness (PWV) after 24 weeks. Although plasma vWF[7] levels decreased only non-significantly after 12 weeks of treatment, an inverse correlation was found between FMD and vWF (R = -0.643, P = 0.007). FMD also inversely correlated with CRP (R = -0.596, P = 0.015). CRP and vWF also correlated with each other (R = 0.598, P = 0.014). PWV and ccIMT showed a positive correlation (R = 0.735, P = 0.038).

Conclusions: Treatment with adalimumab exerted favorable effects on disease activity and endothelial dysfunction. It also ameliorated carotid atherosclerosis and arterial stiffness in patients with early RA. Early adalimumab therapy may have an important role in the prevention and management of vascular comorbidity in RA.
