18701540 The clinical effectiveness of static resting splints in early rheumatoid arthritis: a rand 2008 Oct OBJECTIVE: To evaluate the effectiveness of static resting splints in early RA. METHODS: A multicentre, randomized, trial was conducted. Patients (n = 120) received either static resting splints [positioned with the wrist in neutral, MCP joint (MCPJ) and IP joint (IPJ) in a maximum of 60 degrees and 30 degrees of flexion, respectively] plus standardized occupational therapy or standardized occupational therapy alone. Change in grip strength (Ns), structural impairment (MCPJ ulnar deviation), applied dexterity (Button Board), self-report hand ability [Michigan Hand Outcomes Questionnaire (MHQ)], hand pain and morning hand stiffness were assessed at 0 and 12 months. RESULTS: Data for 56 (97%) splinted and 60 (97%) control group patients were analysed. Splint wear adherence was moderate; 24.5% 'never wore' the splints. The adjusted mean difference between groups for handgrip was -14.2 Ns (P = 0.342; 95% CI -43.7, 5.4); MCPJ ulnar deviation -1.1 degrees (P = 0.657; 95% CI = -6.2, 3.9); dexterity 0.1 s (P = 0.975; 95% CI = -6.6, 6.8) and self-report ability -3.0 on the MHQ score (P = 0.426; 95% CI -10.5, 4.5). Pain scores were unchanged in either group (P = 0.15). The occurrence of morning hand stiffness was reduced in a small group of splinted patients (P = 0.021), but the duration shortened in control patients (P = 0.010). CONCLUSIONS: There was no significant difference between the two interventions on grip strength, deformity, hand function and pain. The data favoured the control group and this study suggests that resting splints should not be used as a routine treatment of patients with early RA.
16014674 Vaccination against influenza in rheumatoid arthritis: the effect of disease modifying dru 2006 Feb OBJECTIVE: To assess the efficacy and safety of vaccination against influenza virus in patients with rheumatoid arthritis, with special emphasis on the effect of disease modifying antirheumatic drugs (DMARDs), including tumour necrosis factor alpha (TNFalpha) blockers. METHODS: 82 rheumatoid patients and 30 healthy controls were vaccinated with a split-virion inactivated vaccine containing 15 mug haemagglutinin (HA) per dose of each of B/Hong Kong/330/2001 (HK), A/Panama/2007/99 (PAN), and A/New Caledonian/20/99 (NC). Disease activity was assessed by tender and swollen joint count, morning stiffness, evaluation of pain, Health Assessment Questionnaire, ESR, and C reactive protein on the day of vaccination and six weeks later. Haemagglutination inhibiting (HI) antibodies were tested by a standard WHO procedure. Response was defined as a fourfold or more rise in HI antibodies six weeks after vaccination, or seroconversion in patients with a non-protective baseline level of antibodies (<1/40). Geometric mean titres (GMT) were calculated to assess the immunity of the whole group. RESULTS: Six weeks after vaccination, a significant increase in GMT for each antigen was observed in both groups, this being higher in the healthy group for HK (p=0.004). The percentage of responders was lower in rheumatoid patients than healthy controls (significant for HK). The percentage of responders was not affected by prednisone or any DMARD, including methotrexate, infliximab, and etanercept. Indices of disease activity remained unchanged. CONCLUSIONS: Influenza virus vaccine generated a good humoral response in rheumatoid patients, although lower than in healthy controls. The response was not affected by the use of prednisone or DMARDs.
19037609 Infiltrations of plasma cells in synovium are highly associated with synovial fluid levels 2009 May Infiltration of plasma cells can be a histopathological hallmark of articular synovium with rheumatoid arthritis (RA). A proliferation-inducing ligand (APRIL) may have key roles in homeostasis and development of B cells, and the differentiation of B cells into plasma cells. This study was designed to explore the relationships between the infiltrations of plasma cells in synovium and the synovial fluid levels of APRIL in inflamed peripheral joints of RA. Synovium and synovial fluid were sampled from 21 RA patients underwent arthroscopic synovectomy for inflamed peripheral joints. The variants of rheumatoid synovium were classified into the follicular and diffuse synovitis by hematoxylin and eosin staining, and the infiltrations of plasma cells in rheumatoid synovium were quantified under the light microscope. The synovial fluid levels of APRIL were measured with the enzyme-linked immunosorbent assay. The mean number of infiltrating plasma cells in synovium and the mean synovial fluid level of APRIL were significantly increased in follicular synovitis compared with those in diffuse synovitis (P = 0.009, and P = 0.018, respectively), and there was a highly positive association between the infiltrations of plasma cells and the synovial fluid levels of APRIL among all of the RA patients (Rs = 0.776, P < 0.001). These findings suggest that the local production of APRIL may be associated with the ectopic lymphoid neogenesis in rheumatoid synovium and may have a role in contributing to the infiltration of plasma cells in synovium within inflamed peripheral joints of RA.
18987777 Pregnancy and rheumatic disease: "by the book" or "by the doc". 2009 Jan Pregnancy is an important condition that can affect and be affected by rheumatic disease. Overall, pregnancy is viewed as a Th2-predominant state, but several Th1-related cytokines are vital to early pregnancy. In rheumatoid arthritis for example, the majority of women improve by the beginning of the second trimester, but the majority (90%) will flare in the first 3 to 4 months postpartum. In contrast, systemic lupus erythematosus has an unpredictable course in pregnancy, leaving most rheumatologists to recommend a disease-quiescent state prior to conception. Other diseases such as scleroderma are less clear because the disease less commonly presents in the childbearing period. Many immunosuppressive medications for the rheumatic diseases are contraindicated in pregnancy because of their mechanisms of action leaving only a select few "safe" medications. Significant heterogeneity between the Food and Drug Administration (FDA) category for a medication and what a rheumatologist does in clinic leads to confusion on how a patient should be treated for active rheumatic disease both peripartum and postpartum, particularly if the patient is breastfeeding. We review the general state of pregnancy and how it is affected by prototypical rheumatic diseases including rheumatoid arthritis and systemic lupus erythematosus. In addition, we present the most commonly used disease-modifying antirheumatic drugs and immunosuppressants and explain the difference between the FDA category and clinical practice among rheumatologists. Finally, we provide some general recommendations on how to manage a rheumatic disease during pregnancy including: (a) preconception planning to ensure no teratogenic medications on board, (b) early disclosure of pregnancy to all caregivers including the rheumatologist, family physician, obstetrician, and maternal-fetal medicine specialist, and (c) planning of safe medication use for acute flare-ups and disease suppression peripartum and postpartum.
18403245 Mean platelet volume (MPV) as an inflammatory marker in ankylosing spondylitis and rheumat 2008 May AIMS: The aim of this retrospective study was to investigate the correlation between MPV and the clinical disease activity indices of rheumatoid arthritis and ankylosing spondylitis. METHODS: The study consisted of 32 active RA patients (males/females: 7/25, mean age: 49+/-13) and 30 active AS patients (males/females: 15/15, mean age: 36+/-12) along with 26 osteoarthritis (OA) patients (males/females: 4/22, mean age: 52+/-8) and 29 age-matched healthy subjects (males/females: 5/24, mean age: 41+/-7) as control groups for RA and AS, respectively. RESULTS: MPV was significantly lower in both AS patients and RA patients with active disease as compared to controls (RA vs OA p<0.001, AS vs healthy subjects p<0.001). After treatment MPV values significantly increased in AS and RA (p<0.001 for all). However, MPV values remained somewhat lower in RA patients than OA patients (p=0.019). There was a negative correlation between MPV values and BASDAI scores in AS patients after two months of treatment (r=-0.507; p=0.004). CONCLUSION: Our results suggest that assessment of MPV may provide additional information about inflammation in AS and RA.
18372277 The membrane proteinase 3 expression on neutrophils was downregulated after treatment with 2008 Apr Proteinase 3 (PR3) expression on neutrophils was examined in rheumatoid arthritis (RA) patients before and after antitumor necrosis factor (TNF)-alpha therapy. Membrane PR3 expression from patients with either an infection or RA significantly increased. Membrane PR3 expression on neutrophils from RA patients treated with infliximab (anti-TNF-alpha antibody) therapy was less than in those without such treatment in a resting state, but the expression later increased after stimulation in vitro. Membrane PR3 expression increased because of the stimulation of TNFalpha, whereas it was significantly suppressed by plasma or alpha(1)-proteinase inhibitor. The condition of patients with RA improved after treatment with infliximab. Membrane PR3 expression on neutrophils in RA patients was downregulated by infliximab. As a result, PR3 might play an important role in the neutrophil-mediated inflammatory reaction in patients with either RA or an infection.
16642406 Paraoxonase and arylesterase levels in rheumatoid arthritis. 2007 Mar It was reported that lipid peroxidation (LPO) products increase in rheumatoid arthritis (RA) patients and increased LPO products reduce many antioxidants. Lipid hydroperoxides (LOOHs) are byproduct of LPO. Paraoxonase (PON), arylesterase (ARE), free sulfhydryl (SH) groups, and ceruloplasmin (CP) are enzymes or proteins with antioxidant characteristics. This study aims to determine the levels of LOOHs and SH, and the activities of PON1, ARE, and CP in RA patients. The study included 47 active RA cases and 23 healthy volunteers. The levels of LOOHs and SH, and the activities of PON1, ARE, and CP were determined using appropriate methods. Student's t test and Spearman's correlation analysis methods were employed in the statistical evaluation. The level of LOOHs was found to be higher (p<0.001), while the level of SH and the activities of PON1, ARE, and CP were found to be lower (p<0.001, <0.001, <0.01, and <0.01, respectively) in the RA patient group when compared with the control group. There was a negative correlation between the level of LOOHs and the activity of PON1 in the patient group (r= -0.420 and p<0.01). The results of our study indicate increased oxidant and decreased antioxidant presence in RA patients. PON1 and ARE are known to have antiatherosclerotic effects in addition to their antioxidant characteristics. As the decrease in these antioxidants, resulting from increased oxidative stress in RA patients, development of atherosclerosis besides tissue injury seems inevitable.
16512396 [Cerebrovascular disturbances in rheumatoid arthritis]. 2006 Rheumatoid arthritis (RA) is a diffuse connective tissue disease and a multi-system disorder with inflammatory process affecting joints in the first place. RA is found in 1 to 3% of population; the first signs of it are usually found in people aged 35 to 50. Neurological pathology in RA is manifested by cervicocranialgia, cervical myelopathy, pathological changes in the upper cervical spine, and cerebral disorders. However, exact mechanisms of the development of central nervous system (CNS) lesions in RA have not been presented. The aim of this study was to clarify the pathophysiological mechanisms and clinical peculiarities of cerebral disturbances in RA. The subjects were 42 female patients, who underwent clinical, neurological, clinicolaboratory, immunological, and clinicophysiological examination. Subjective and objective symptoms were studied; the following syndromes of CNS pathology were distinguished: initial manifestations of cerebral functional insufficiency; disseminated cerebral micro symptoms; focal cerebral lesion. These disorders were accompanied by changes in biochemical parameters which evidenced the presence of connective tissue destruction and immune inflammation. Immunological tests revealed elevation of the level of myelin basic protein antibodies, which correlated with the degree of neurological disturbances and the duration of the disease. The level of myeloperoxidase was elevated, but the degree of this elevation did not depend on the degree of the cerebral disorder and displayed a negative correlation with the duration of the disease. The results of the study demonstrate primary lesion of small vessels in RA--secondary vasculitis followed by demyelinization of CNS white substance. Thus, three forms of cerebrovascular pathology, caused by acute or chronic cerebral vascular insufficiency in RA can be distinguished: initial manifestations of cerebral circulation insufficiency; discirculatory encephalopathy; transient cerebral circulation disturbances and cerebral stroke.
18953942 [The application of combined detection of autoantibodies in primary Sjögren's syndrome]. 2008 May OBJECTIVE: To compare the specificity and sensitivity of antibodies against SSA and SSB, anti-M3 receptor polypeptide antibodies, anti-alpha-fodrin (IgG) antibodies in primary Sjögren's syndrome (pSS). METHODS: One hundred and ten pSS patients (mean age was 49.2 +/- 14. 8, mean disease duration was 5.6 +/- 4.6), 80 systemic lupus erythematosus (SLE) patients (mean age was 25.5 +/- 4.6, mean disease duration was 2.5 +/- 1.2) and 80 rheumatoid arthritis (RA) patients (mean age was 44.6 +/- 3.5, mean disease duration was 4.2 +/- 1.1) were studied. Enzyme-linked immunosorbent assay was used to measure these antibodies. RESULTS: The seropositive rates of anti-SSA, anti-SSB antibodies, anti-M3 receptor polypeptide antibodies and anti-alpha-fodrin (IgG) antibodies were 45.5%, 30.9%,78.2% and 77.3%, respectively in pSS. They were much higher than those in RA and SLE patients (P < 0.05). Specificities of SSA, SSB antibodies, anti-M3 receptor antibodies and anti-alpha-fodrin IgG were 83.8%, 97.7%, 92.0% and 90.0% respectively. With the combination of these antibodies in the diagnosis of pSS, the sensitivity can be increased at least to 88.2% and the specificity was not decreased significantly. CONCLUSION: Combination of these antibodies can significantly improve the sensitivity of these antibodies in the diagnosis of pSS. Anti-SSA and SSB antibodies, anti-M3 receptor antibodies and anti-alpha-fodrin (IgG) antibodies are specific antibodies for the diagnosis of pSS.
18392950 Release of heat shock protein 70 and the effects of extracellular heat shock protein 70 on 2008 Sep It has recently been suggested that heat shock protein (Hsp) 70, an intracellular protein, can be released into the extracellular compartment and exert important immunomodulatory functions. Although elevated Hsp70 has been found in synovial fluid from patients with rheumatoid arthritis (RA), its sources and extracellular functions remain unclear. In this study, we explored whether stress response such as heat stress or exposure to tumor necrosis factor-alpha (TNF-alpha) could induce Hsp70 release from RA fibroblast-like synoviocytes (FLSs) and whether extracellular Hsp70 would stimulate cytokine production in RA FLSs. Cultured FLSs were obtained from patients with RA. The expression of intracellular Hsp70 was studied by Western blot. Hsp70 release and the production of interleukin (IL)-6, IL-8, and IL-10 by RA FLSs were studied by specific enzyme-linked immunosorbent assays. The levels of Toll-like receptor (TLR) 2 and 4 mRNA and protein in FLSs were analyzed using reverse transcription-polymerase chain reaction and Western blotting. Treatment with sublethal heat shock or TNF-alpha results in the up-regulation of intracellular Hsp70 in FLSs and Hsp70 release from RA FLSs. In vitro studies show that extracellular Hsp70 can induce anti-inflammatory cytokine IL-10 production in FLSs. The mRNA and protein expression of TLR2 and TLR4 was demonstrated in FLSs, and TLR4 blocking abrogated the up-regulatory effects of Hsp70 on IL-10 production. Thus, these results lend support to the hypothesis that Hsp70 is actively released from FLSs in response to heat shock or TNF-alpha and Hsp70 may be a major paracrine/autocrine inducer of IL-10 production in FLSs via TLR4.
17662149 Diurnal secretion of growth hormone, cortisol, and dehydroepiandrosterone in pre- and peri 2007 Rheumatoid arthritis (RA) is associated with neuroendocrine and immunologic dysfunction leading to rheumatoid cachexia. Although excess proinflammatory cytokines can decrease somatotropic axis activity, little is known about the effects of RA on growth hormone/insulin-like growth factor-1 (GH/IGF-I) axis function. We tested the hypothesis that patients with active RA exhibit decreased GH/IGF-I axis activity. To do so, we conducted a pilot case-control study at a clinical research center in 7 pre- and perimenopausal women with active RA and 10 age- and body mass index-matched healthy women. Participants underwent blood sampling every 20 minutes for 24 hours (8 a.m. to 8 a.m.), and sera were assayed for GH, cortisol, and dehydroepiandrosterone (DHEA). Sera obtained after overnight fasting were assayed for IGF-I, IGF-binding protein (IGFBP)-1, IGFBP-3, C-reactive protein (CRP), interleukin-6 (IL-6), glucose, insulin, and lipids. Body composition and bone mineral density were evaluated by DEXA (dual emission x-ray absorptiometry) scans. In patients with RA, mean disease duration was 7.6 +/- 6.8 years, and erythrocyte sedimentation rate, CRP, and IL-6 were elevated. GH half-life was shorter than in control subjects (p = 0.0037), with no other significant group differences in GH deconvolution parameters or approximate entropy scores. IGF-I (p = 0.05) and IGFBP-3 (p = 0.058) were lower, whereas IGFBP-1 tended to be higher (p = 0.066), in patients with RA, with nonsignificantly increased 24-hour total GH production rates. There were no significant group differences in cortisol or DHEA secretion. Lean body mass was lower in patients with RA (p = 0.019), particularly in the legs (p = 0.01). Women with active RA exhibit a trend toward GH insensitivity and relatively diminished diurnal cortisol and DHEA secretion for their state of inflammation. Whether these changes contribute to rheumatoid cachexia remains to be determined. TRIAL REGISTRATION NUMBER: NCT00034060.
18534016 The human anti-IL-1 beta monoclonal antibody ACZ885 is effective in joint inflammation mod 2008 INTRODUCTION: IL-1beta is a proinflammatory cytokine driving joint inflammation as well as systemic signs of inflammation, such as fever and acute phase protein production. METHODS: ACZ885, a fully human monoclonal antibody that neutralizes the bioactivity of human IL-1beta, was generated to study the potent and long-lasting neutralization of IL-1beta in mechanistic animal models as well as in a proof-of-concept study in patients with rheumatoid arthritis (RA). RESULTS: The mouse IL-1 receptor cross-reacts with human IL-1beta, and it was demonstrated that ACZ885 can completely suppress IL-1beta-mediated joint inflammation and cartilage destruction in mice. This observation prompted us to study the safety, tolerability and pharmacodynamic activity of ACZ885 in RA patients in a small proof-of-concept study--the first to be conducted in humans. Patients with active RA despite treatment with stable doses of methotrexate were enrolled in this dose escalation study. The first 32 patients were split into four cohorts of eight patients each (six were randomly assigned to active treatment and two to placebo). ACZ885 doses were 0.3, 1, 3 and 10 mg/kg, administered intravenously on days 1 and 15. To explore efficacy within 6 weeks of treatment, an additional 21 patients were randomly assigned to the 10 mg/kg cohort, resulting in a total of 20 patients dosed with 10 mg/kg and 15 patients treated with placebo. There was clinical improvement (American College of Rheumatology 20% improvement criteria) at week 6 in the 10 mg/kg treatment group; however, this did not reach statistical significance (P = 0.085). A statistically significant reduction in disease activity score was observed after 4 weeks in the 10 mg/kg group. Onset of action was rapid, because most responders exhibited improvement in their symptoms within the first 3 weeks. C-reactive protein levels decreased in patients treated with ACZ885 within 1 week. ACZ885 was well tolerated. Three patients receiving ACZ885 developed infectious episodes that required treatment. No anti-ACZ885 antibodies were detected during the study. CONCLUSION: ACZ885 administration to methotrexate-refractory patients resulted in clinical improvement in a subset of patients. Additional studies to characterize efficacy in RA and to determine the optimal dose regimen appear warranted. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT00619905.
16633707 Articular damage in late rheumatoid arthritis. 2007 Mar This study aims to examine the long-term articular damage in rheumatoid arthritis (RA) patients according to rheumatoid arthritis articular damage (RAAD) score and to evaluate the parameters correlated with this score. The RAAD score was assessed in 85 RA patients who had the disease for more than 10 years. Patients were divided into three groups according to duration of the disease: group 1, 10-14 years; group 2, 15-19 years; and group 3, more than 20 years. Patients were also divided into three groups according to the time of initiation of treatment with disease-modifying antirheumatic drugs: group A, within the first 2 years, group B, between 2 and 5 years; and group C, after 5 years. We investigated the RAAD score relationship between groups 1, 2, 3; groups A, B, C; sex; drug compliance; age of onset of the disease; and Health Assessment Questionnaire (HAQ). We observed significant differences in RAAD scores according to groups 1, 2, 3 (p<0.01), but not to groups A, B, C; sex; or drug compliance (p>0.05). While the RAAD score correlated well with the HAQ (r=0.560, p<0.001), it did not correlate with the age at onset of the disease (p>0.05). As RA is not a benign disease and articular damage progresses over time, the goal of RA therapy must be to maintain a response before the onset of irreversible damage and loss of function.
15627197 Anti-TNFalpha therapy in rheumatoid arthritis and autoimmunity. 2006 Jan The aim of the study was to evaluate a panel of autoantibodies in patients affected by rheumatoid arthritis (RA) treated with anti-TNFalpha blockers, and to consider a different autoantibody induction effect by infliximab and etanercept; and in addition to evaluate in these cases a relationship between antinuclear antibody (ANA) titre and both C-reactive protein (CRP) and Blys levels. Fifty-four patients (8 men, 46 women, mean age 51.4 years, mean duration of disease 13.6 years) affected by refractory RA were treated with anti-TNFalpha blockers for 12 consecutive months; 43 patients were given infliximab and 11 etanercept. At baseline and every 4 months a panel of autoantibodies consisting of rheumatoid factor, antinuclear, anti-double-stranded DNA, anti-ENA, anti-mitochondrial, anti-thyroid and anti-neutrophil cytoplasmic antibodies (ANCA) was tested. At the same time CRP level was measured. Blys level was determined at baseline and after 1 year in five cases that developed a strong positivity for ANA during infliximab therapy. In 41 cases (95.3%) treated with infliximab, ANA were detected on at least one occasion, and in almost half of these cases the titre was very high, equal to or higher than 1:1.280. On the other hand, patients treated with etanercept presented ANA positivity in a lower percentage of cases and at a low titre. No correlation was found between ANA titre and CRP level; Blys level did not present a constant trend in patients who developed a very high positivity for ANA. Anti-double-stranded DNA, anti-thyroid or ANCA were found only in a few patients, in the absence of a clinical picture indicative of systemic lupus erythematosus, autoimmune thyroiditis or ANCA-associated vasculitis. A different incidence of ANA positivity was found in infliximab- and etanercept-treated RA patients; this finding might be due to the partially different method of inhibition of TNFalpha between the two drugs. Both CRP and Blys do not seem to participate in this phenomenon. Other autoantibodies were detected in a few patients, but no case of onset of new autoimmune disorders was observed.
18544059 Histoplasmosis clinically imitating cutaneous malignancy. 2008 Oct Disseminated histoplasmosis can have a varied presentation when it affects the skin. Presentation mimicking a cutaneous neoplasm is an uncommon manifestation. We present the case of an 86-year-old man presenting with a cutaneous lesion clinically suspicious for malignancy that was ultimately determined to be his first clinical manifestation of disseminated histoplasmosis after biopsy for histopathologic analysis. Microscopically, the lesion was a nodule with an eroded epidermis overlying a dense dermal inflammatory process. The infiltrate was characterized by numerous epithelioid histiocytes admixed with acute and chronic inflammation. On closer inspection, numerous 2-4 mum intracellular spores surrounded by a clear halo were identified. The organisms were highlighted with periodic acid schiff (PAS) stain. We present this case to highlight a unique presentation of disseminated histoplasmosis. Although this presentation is uncommon, it serves as a reminder that histopathologic confirmation of clinical diagnoses is important before undertaking more invasive procedures such as excision.
19210870 Cost-effectiveness of infliximab in the treatment of rheumatoid arthritis in clinical prac 2008 Nov OBJECTIVE: We evaluated the cost-effectiveness of infliximab therapy in Finnish RA patients in a real-life clinical setting and identified factors influencing it, using the national register of biological treatment (ROB-FIN). METHODS: A cost-utility analysis was performed, derived from EQ-5D, and related to HAQ score and disease activity using multiple regression. QALYs were calculated based on these utilities, using patient-level data up to the last control registered. Cost-effectiveness analyses included costs per ACR50 responder, and costs per low DAS28 score (<3.2) achieved, in combination with a clinically significant improvement (>1.2). The costs considered were direct medical costs of infliximab and cost of intravenous infusion. Patient-level costs were calculated based on dose and dosage frequency, and were related to the difference in QALYs resulting from infliximab therapy. RESULTS: The 297 patients had been treated with infliximab for an average of 21 months. The HAQ score and patient's global assessment improved significantly on infliximab therapy. More than two-thirds of the patients achieved a clinically important improvement in HAQ. A QALY gain occurred in 76%. 35% of these had an incremental cost-effectiveness ratio of < or =40,000 Euro/QALY gained, the median cost being 51,884 Euro. The cost per QALY gained was significantly lower for patients achieving an ACR50 response at 3, 12 and 24 months. CONCLUSION: Treatment with infliximab and aiming at ACR50 response appears cost-effective, remembering the restrictions of an observational study set up. Current Care guidelines, which require sufficient disease control when deciding on continuing biological therapy, get support from these findings.
18651058 [Early rheumatoid arthritis: a prospective study on how to induce the remission]. 2008 Apr OBJECTIVES: To investigate whether the aggressive use of DMARDs can control the clinical disease in the early arthritis, to define new parameters of the disease aggressivity and to study the effectiveness of RMN in comparison with RX focusing on the articular erosions. METHODS: 45 patients having a case of early arthritis (less 6 months) with 3 or more swollen joints were recruited and treated with 80 mg of steroids in order to distinguish persistent arthritis from non persistent ones. Afterward we began to use DMARDs with persistent arthritis and, if it wasn't helpful, we shifted to anti-TNFalpha therapy. The clinical response was valued by SDAI. RESULTS: After 1 year our therapeutic approach showed a remission in 60% of the patients. The 82% of remaining obtained a significant SDAI improvement and only in 3 cases we used anti-TNFalpha due to a persistent high disease activity. Anti-CCp were positive in 46% of patients in remission and in 53% of the rest. The bone erosions were present in 4 patients only and they were detected by RMN, only 2 by RX. CONCLUSIONS: We observed a clinical remission in the 60% of patients treated with aggressive DMARDs. During our trial, anti-CCp weren't predictive about the therapy response. We observed that RMN is more effective than RX in detecting erosions and it's necessary for diagnosis and follow-up of early arthritis.
17621797 [Role of imaging methods in the early diagnosis of rheumatoid arthritis]. 2006 Oct 19 Because of the good contrast obtained in soft tissues, ultrasound permits differentiation of the exudative and proliferative synovial tissue changes, as well as tenosynovitis. Superficial cartilage and bone lesions or erosions can be detected through ultrasound earlier than with conventional radiodiagnostics. The use of power Doppler sonography with ultrasound contrast agents is especially helpful in the further differentiation of the synovial inflammatory process and hence, progression of the destructive processes in the joint can be more clearly evaluated. Arthrosonography aids in the diagnosis of early arthritis, particularly in patients without pathological radiological findings and suspicious clinical results. Moreover, it permits sound assessment of the disease progression and hence, therapeutic monitoring. The method is patient friendly, has high diagnostic value and is an integral component in the clarification of arthritic symptoms.
17440707 [Correction of rheumatic forefoot. The value of a combined arthrodesis of the first toe an 2007 May INTRODUCTION: Resection of the metatarsal heads is an established procedure for the therapy of rheumatic forefoot deformations. However, a recurrence of lateral deviation of the lesser toes and painful plantar keratosis remain a challenging problem for the treatment of these patients. The aim of this study was to evaluate our results in cases of rheumatoid forefoot deformities. We performed a resection of the metatarsal heads 2-5 in combination with an arthrodesis of the first toe and resection of keratosis by the plantar approach. MATERIAL AND METHODS: Fifteen patients (20 feet) were followed-up clinically and radiologically using the American Orthopedic Foot and Ankle Society (AOFAS), Miehlke-, and Larsen scores. RESULTS: Average follow-up time was 3.5 years (range: 1.5-7.5 years). An average AOFAS score of 81/90 was found for the hallux and 90/100 for the lesser toes. A total of 18 feet were rated as pain free, while two feet showed some residual pain. Every case showed an harmonic cascade of the resection. All patients stated that the operation had improved their quality of life and that they would consent to undergoing it again. CONCLUSION: Our results after arthrodesis of MP-1 and resection of the metatarsal heads 2-5 using the plantar approach were good compared to the data published in the literature.
18173922 Somatoform dissociation and traumatic experiences in patients with rheumatoid arthritis an 2007 Nov OBJECTIVE: Trauma and dissociation tend to be interrelated. The objective of this study was to examine the frequency of traumatic experiences and somatoform dissociation in patients with fibromyalgia syndrome (FMS) or rheumatoid arthritis (RA), two conditions that are both characterized by pain and disability. METHODS: Patients with a diagnosis of FMS (2 male, 26 female; mean age 42 +/- 11 years) or RA (5 male, 46 female; mean age 46 +/- 10 years) completed the Fibromyalgia Impact Questionnaire (FIQ), the Somatoform Dissociation Questionnaire (SDQ), and the Traumatic Experience Checklist (TEC). RESULTS: Patients with FMS reported significantly higher levels of various forms of traumatization and dissociation than patients with RA. In patients with FMS, but not in patients with RA, there was a significant correlation between traumatization and dissociative symptoms. A possible dissociative disorder was indicated in 10% of the patients with FMS and 2% of the patients with RA. CONCLUSION: Traumatization experiences are frequent in FMS, but as compared to conversion disorder or dissociative identity disorder only a small subgroup of patients with FMS or RA shows the combination of traumatization and somatoform dissociation. The observation of somatoform dissociation calls for a broad treatment approach with a special role of the psychologist or psychiatrist.
