16899500 | A comparison of clinical vs ultrasound determined synovitis in rheumatoid arthritis utiliz | 2007 Mar | OBJECTIVES: Synovitis in rheumatoid arthritis (RA) is assessed clinically by the presence of joint tenderness and swelling. Synovial thickening and increased vascularity may also be detected by high-resolution ultrasonography (US) and power Doppler (PD). This study investigated the relationship between clinical and sonographic features of synovial disease utilizing US, PD and the contrast agent Sono-Vue. METHODS: Forty RA patients were recruited. One proximal inter-phalangeal or metacarpophalangeal joint was selected per patient, as being unambiguously either: swollen and tender, just swollen, just tender or neither swollen nor tender (Nil). Ten joints were selected per clinical group. On US, the mean synovial thickness was measured and synovial hypertrophy and erosions were graded subjectively. Synovial vascularity demonstrated by PD was scored subjectively pre- and post-contrast. RESULTS: All grades of synovial vascularity were found in each clinical group including the Nil group. There were significant differences between the four clinical groups for both synovial hypertrophy (P = 0.024) and PD scores pre- (P = 0.022) and post- (P = 0.039) contrast. Tender-only joints showed significantly less vascularity than other groups. Post-contrast, the median PD scores increased in all but the Nil group, in some cases from the normal to abnormal range. CONCLUSION: Synovitis demonstrated by US and PD is not predicted by patterns of disease as described by joint swelling and tenderness despite unambiguous selection of joints. Synovial vascularity was the least in tender-only joints and was heterogeneous in all other groups, including Nil joints. These findings question the reliability of traditional clinical signs in RA synovitis assessment. | |
16082630 | Validation of single-factor structure and scoring protocol for the Health Assessment Quest | 2005 Aug 15 | OBJECTIVE: The extensively used Health Assessment Questionnaire Disability Index (HAQ-DI) has been well received by the research and clinical community, notably because of its measurement strengths including reliability and stability of scores over time, utility in observational studies and clinical trials, predictive relationship with morbidity and mortality in rheumatoid arthritis (RA), and its translation for use in different countries. However, HAQ-DI scoring has not been validated. The purpose of this study was to examine the structural validity of the HAQ-DI and evaluate the latent factors underlying HAQ-DI scoring. METHODS: This study used a cross-validation approach on a total of 278 patients with RA. Exploratory and confirmatory factor analyses were performed. RESULTS: Results yielded a single-factor HAQ-DI score, which favored the current scoring system of the HAQ-DI. Additionally, modification indices suggested improved model fit with the secondary inclusion of correlated residual scores from a motor skills subdomain. CONCLUSION: The current study provides the first validation of the HAQ-DI scoring system as determined by its latent factor structure. In addition, the findings suggest some benefit from a secondary interpretation of the scores based on domains that measure motor skills. | |
17114190 | A randomised, double-blind, placebo-controlled trial of a recombinant version of human alp | 2007 May | BACKGROUND: Rheumatoid arthritis (RA) tends to remit during pregnancy, with more patients achieving remission in the third trimester, coinciding with an increase in levels of alpha-fetoprotein (AFP). In vitro and animal studies have shown that AFP has immunomodulatory properties. MM-093 is a non-glycosylated, recombinant version of human AFP. OBJECTIVE: To assess the safety, tolerability and clinical effects of MM-093 during a 12-week, randomised, double-blind, placebo-controlled study. METHODS: 12 patients with RA, who had active disease and were on stable doses of methotrexate, received weekly subcutaneous injections of placebo or 21 mg of MM-093. Assessments were carried out at baseline and weekly thereafter. RESULTS: Baseline characteristics were similar in both groups. There was one dropout in the placebo group, due to flare of disease. Treatment with MM-093 was well tolerated. No serious adverse event was observed. By day 85, MM-093 produced a significant mean improvement from baseline in Disease Activity Score 28 (DAS28; 0.913 vs 0.008, p = 0.033) and patient's global assessment (28.9% vs -36.3%, p = 0.02) compared with placebo. CONCLUSION: This is the first randomised, controlled trial of MM-093, a recombinant version of human AFP, in patients with RA. MM-093 was well tolerated. Evidence of efficacy was observed, suggesting that MM-093 may have therapeutic potential in RA. | |
15673528 | Measurement of cartilage volumes in rheumatoid arthritis using MRI. | 2005 Jan | MRI is a valuable imaging modality for assessment of the articular cartilage in rheumatoid arthritis (RA) and is potentially of use in monitoring disease progression and response to therapy. In this study, we investigated the sources of error in volume measurements obtained by segmentation of MR images of knee cartilage in patients with RA and followed cartilage volume in a group of RA patients for 12 months. 23 RA patient volunteers were recruited for knee imaging. Six subjects were imaged at baseline only, six were imaged at baseline and again within an hour in the same imaging session, six subjects were imaged at baseline and 7 days, and 17 subjects were imaged at baseline, 4+/-2 months and 12 months. Imaging was performed at 1.0 T using a three-dimensional spoiled gradient-echo sequence with fat-suppression. Manual image segmentation was performed once or twice on the lateral tibial, medial tibial, patellar and femoral compartment by either one or two segmenters. Coefficients of variation (CoV) for repeated volume measurement of total cartilage were 2.2% (same segmenter, same scan), 5.2% (different segmenter, same scan), 4.9% (same segmenter, different scan, same session), and 4.4% (same segmenter, different scan, different session). Over the 12 month duration of the study there was no significant change in total cartilage volume, nor were there significant changes in volume in any individual compartment. This measurement technique is reproducible, but any net change in cartilage volume over 1 year is very small. | |
16855170 | Neuroendocrine modulation induced by selective blockade of TNF-alpha in rheumatoid arthrit | 2006 Jun | Tumor necrosis factor-alpha (TNFalpha) is a main actor in the pathogenesis of rheumatoid arthritis (RA), interacting with other molecules in complex mechanisms. The neuroendocrine system is known to be involved and Chromogranin A (CHGA) serum levels are elevated in patients with RA. We evaluated the effect of the selective blockade of TNF-alpha, induced by treatment with anti-TNF-alpha monoclonal antibodies (mAbs), on the serum levels of CHGA and on its correlation with TNF-alpha and TNF-alpha receptors (TNFRs) serum levels. Seven patients with RA have been treated with the anti-TNF-alpha mAb, infliximab. We measured the serum levels of TNF-alpha, its receptors (tumor necrosis factor receptor-I [TNFR-I] and tumor necrosis factor receptor-II [TNFR-II]), and CHGA before and during the treatment. We also measured, as a control, the serum levels of CHGA, TNF-alpha, and soluble TNFRs in 14 patients who were being treated with infliximab, adalimumab, or etanercept and in 20 matching negative controls. The serum levels of TNFR-I and TNFR-II, which are a sensitive marker for the TNF-alpha pathway, correlated with those of CHGA before treatment (Pearson's coefficient, respectively, 0.59 and 0.53). Treatment with anti-TNF-alpha mAb provided a significant clinical response in all patients and the correlation between CHGA and TNFR-I and TNFR-II was no more evident during treatment (respectively, -0.09 and -0.07). TNF-alpha blockade allows a clinical effect in patients with RA and modifies the correlation between CHGA and TNFRs, suggesting that TNF-alpha and CHGA reciprocally interfere in the pathogenesis of RA, through intermediate adaptors, whose identification warrants further studies. | |
16267598 | The incidence of Proteus mirabilis infection increases in patients on treatment but does n | 2006 Jul | The aim of this study is to determine whether treatment increases the levels of anti-Proteus antibodies (APA) in patients with rheumatoid arthritis (RA). The blood samples of 32 patients suffering from RA who were recruited in our previous study and continued to participate in our follow-up study were collected after 1 year. Their first and follow-up samples were analysed for the presence of IgG isotype and total immunoglobulins (IgG+IgA+IgM) against Proteus mirabalis (PM) using enzyme-linked immunosorbent assay with two kinds of antigen preparations: whole bacteria and sodium dodecyl sulphate (SDS) lysed bacterial extract. All patients were treated with methotrexate and hydroxychloroquine with adequate dose of non-steroidal anti-inflammatory drug. After 1 year, 11 patients were in clinical remission [erythrocyte sedimentation rate (ESR) less than 30 mm/h and C-reactive protein (CRP) less than or equal to 10 mg/l], while the rest of the 21 were in the state of active disease. Correlation and Student's t test were used for statistical analysis. APA titres were significantly elevated in patients after 1 year of therapy. However, the rise was not different between patients who were in clinical remission and those in the state of active disease. APA titre increases in the treatment of RA, and the probable mechanisms are discussed. | |
15971419 | Inhibition of NF-kappaB signaling by fenofibrate, a peroxisome proliferator-activated rece | 2005 May | OBJECTIVES: Inflammatory mediators such as interleukin-6 and tumor necrosis factor-alpha play an important role in the pathogenesis of rheumatoid arthritis (RA) by promoting chronic inflammation and joint damage. NF-kappaB is a transcriptional activator of genes for these cytokines. It also plays an important role in the regulation of osteoclast differentiation which plays a key role in joint destruction in RA. Ligands for peroxisome proliferator-activated receptor (PPAR) -gamma have recently been reported to inhibit the development of RA. In this study, we investigated the role of PPARalpha in RA. METHODS: We analyzed the protein expression of PPAR-alpha and -gamma in rheumatoid synovial fibroblasts (RSF) from RA patients and analyzed the effects of ligands for PPAR-alpha and -gamma on cytokine production from RSF NF-kappaB activations in RSF and osteoclast differentiation from osteocalst progenitor in the peripheral blood. Moreover, we analyzed the effects of oral administration of PPAR-alpha and -gamma ligands on the development of adjuvant-induced arthritis (AIA) in female Lewis rats. RESULTS: We confirmed the expression of PPAR-alpha in RSF and also demonstrated that fenofibrate, a ligand for PPAR-alpha, inhibited cytokine production from RSF, NF- kappaB activation in RSF, and osteoclast differentiation from osteoclast progenitor cells. Furthermore, we demonstrated that fenofibrate inhibits the development of arthritis in a rat model of human RA. CONCLUSIONS: These results indicate that fenofibrate suppresses the development of arthritis by inhibition of NF-kappaB signaling; therefore, this compound offers possible anti-rheumatic drug. | |
16391482 | [Reduction of endogenous regulation in internal medicine patients]. | 2005 Dec | BACKGROUND: General health-related questionnaires on quality of life do not satisfactorily distinguish between healthy and sick people. One of the reasons cited for this lack is too much mental influence. This is why we developed a questionnaire on endogenous regulation (eR) that reflects the regulatory state of various vegetative functions. OBJECTIVE: The current study examines whether the short version eR questionnaire is able to distinguish between healthy people and internal medicine patients. PATIENTS AND METHODS: 408 participants were included in the study (284 females, 124 males). Among these were patients with colorectal cancer (n = 49), breast cancer (n = 95), diabetes mellitus (type 1: n = 20, type 2: n = 40), coronary disease (n = 39), rheumatoid illnesses (n = 28) and multimorbid patients (n = 22) as well as a healthy control group (n = 115). In addition to the eR questionnaire the study also used the Hospital Anxiety and Depression Scale (HADS), the short questionnaire on self-regulation and questions on the vegetative status. RESULTS: The healthy control group showed the highest eR, with an estimated average of M = 29.8. Patients with breast cancer, diabetes mellitus type 2, coronary disease and rheumatoid illnesses reveal a significantly lowered eR. Multimorbid patients show the lowest eR. Patients with cancer of the colon and diabetes type 1 were measured at M = 27.9 and M = 27.3 respectively and showed no significantly lowered estimated average compared to the control group. A high eR significantly correlates (p < 0.002) with the following parameters: low levels of anxiety (r = 49) and depression (r = 0.36), high self-regulation (r = 0.34), morning type (r = 0.40), less congestive perspiration (r = 0.38), less shivering (r = 0.23), dysmenorrhoea (r = 0.38) and allergies (r = 0.17). CONCLUSION: Healthy people show the highest, multimorbid patients the lowest eR. Consistent relations to health, illness, heat regulation and personality presence have been shown. Further studies to clarify clinical relevance are necessary. | |
15996202 | Immune effects of therapy with Adalimumab in patients with rheumatoid arthritis. | 2005 Aug | The aim of this study was to assess the effect of Adalimumab on different immune parameters in patients with RA. Adalimumab was administered (40 mg every other week for 26 weeks) to eight patients with RA that were refractory to conventional drug therapy. Peripheral blood samples were obtained at days 0, 15 and 180 of Adalimumab therapy, and the following immune parameters were assessed: Number, phenotype, and function of regulatory T lymphocytes. The induction of apoptosis of immune cells and the in vitro and in vivo reactivity towards M. tuberculosis were also analysed. All patients responded to Adalimumab (ACR response 50-70), and a modest but significant increase in the number and function of regulatory T cells was observed at day 15 of anti-TNF-alpha therapy. In addition, an increased percent of apoptotic cells was detected in the peripheral blood at day 15 of Adalimumab therapy. Unexpectedly, most of these effects were not further observed at day 180. However, two patients showed a persistent and marked reduction in the reactivity to M. tuberculosis. Although we have found that Adalimumab affects the number and function of regulatory T lymphocytes, and the apoptosis of immune cells, these effects are transient and its possible causal relationship with the therapeutic activity of this biological agent remains to be determined. Nevertheless, the down-regulatory effect of Adalimumab on the reactivity to M. tuberculosis could be related to an enhanced risk of tuberculosis reactivation. | |
16760833 | [Cutaneous vasculitis with necrotic ulcers in rheumatoid arthritis: treatment with anti-TN | 2006 May | INTRODUCTION: Anti-TNFalpha has occasionally been used in the treatment of recalcitrant forms of systemic vasculitis such as Behçet's disease, Wegener's granulomatosis and Churg-Strauss syndrome. We report on the outcome of treatment in rheumatoid arthritis patients with cutaneous vasculitis lesions on anti-TNFalpha. OBSERVATIONS: Two patients with rheumatoid arthritis present for several years had necrotic ulcers of the lower limbs due to cutaneous vasculitis. After the failure of various immunosuppressive drugs (cyclophosphamide, azathioprine, methotrexate), the two patients were treated with anti-TNFalpha: infliximab in the first case and adalimumab in the second. Cutaneous ulcers healed within two to four months of the start of anti-TNFalpha treatment. Despite ongoing anti-TNFalpha treatment, these cutaneous ulcers relapsed four to six months after complete healing. CONCLUSION: Initially spectacular healing of cutaneous vasculitis ulcers under anti-TNF alpha treatment followed by relapse after several months of treatment is suggestive of an escape mechanism. | |
16013933 | [Infliximab in rheumatoid arthritis-use in a third level hospital]. | 2005 Mar | OBJECTIVES: To study the conditions of infliximab use in rheumatoid arthritis, as well as the effectiveness and adverse effects of this therapy, and to perform an economic assessment of infliximab therapy in a third-level hospital. MATERIAL AND METHODS: A retrospective study was performed including patients treated with infliximab from January 2001 to March 2003. RESULTS: Twenty-five percent of patients received doses greater than 3 mg/kg, and 12% of them at intervals shorter than 8 weeks; 78% also received methotrexate concurrently. Adverse effects reported were similar in type to those described in the pro-duct's data sheet. Regarding therapy effectiveness, objective para-meters were seen to improve, less so the remaining parameters. Therapy cost was 5.6% of day hospital costs. CONCLUSIONS: Anti-TNF drugs are a relevant alternative in the treatment of rheumatoid arthritis because of their effectiveness-safety profile, but understanding their frame of use and following recommendations issued by scientific societies are important considerations. | |
15978314 | Retrospective study of the costs of care during the first year of therapy with etanercept | 2005 May | OBJECTIVE: The aim of this work was to retrospectively examine the costs of therapy with etanercept and infliximab, among patients aged > or = 65 years with rheumatoid arthritis (RA), from a health-care system perspective. METHODS: Data from 2 large, automated US health-care claims databases (Constella COMPASS and Ingenix LabRx) were pooled for the analyses. Each database is comprised of paid facility, professional service, and retail (ie, outpatient) pharmacy claims from participating health plans. Using the 2 databases, all RA patients aged > =65 years were identified who began therapy with etanercept or infliximab between July 1, 1999 (Constella COMPASS), or January 1, 2001 (Ingenix LabRx), and December 31, 2002. Costs of RA-related care (including study drugs, selected medications, and outpatient encounters for RA) and non-RA-related care (all other medications and services) for patients in the 2 treatment groups were assessed, in US dollars, over a 1-year period after therapy initiation. RESULTS: A total of 280 RA patients aged > or = 65 years initiated therapy with etanercept (n = 99) or infliximab (n = 181) and met all other selection criteria. Etanercept patients were younger than infliximab patients (mean [SD] age, 70.5 [4.6] vs 71.8 [4.6] years; P = 0.04), were less likely to be enrolled in a managed care organization (76.7% vs 87.8%; P < 0.01), and had fewer pretreatment rheumatologist visits (mean [SD], 1.3 [2.3] vs 2.2 [3.8]; P = 0.04). Other characteristics, including pretreatment levels of other types of health-care utilization, were generally similar. Mean (95% CI) total cost of RA-related care was lower for etanercept patients in both databases (US 12,159 dollars [US 10,795 dollars-US 13,380 dollars] for etanercept vs US 22,347 dollars [US 20,808 dollars-US 23,912 dollars] for infliximab in one, and US 14,297 [US 12,238 dollars-US 16,326 dollars] for etanercept vs US 22,154 dollars [US 19,688 dollars-US 24,703 dollars] for infliximab in the other), primarily due to lower costs of anti-tumor necrosis factor therapy (US 10,015 dollars [US 8754 dollars-US 11,224 dollars] for etanercept vs US 18,611 dollars [US 17,169 dollars-US 20,023 dollars] for infliximab in one database; US 11,917 dollars [US 10,128 dollars-US 13,480 dollars] for etanercept vs US 16,759 dollars [US 14,551 dollars-US 19,062 dollars] for infliximab in the other). Mean (95% CI) costs of non-RA-related care were similar among etanercept and infliximab patients in both databases (US 13,100 dollars [US 8956 dollars-US 18,377 dollars] for etanercept vs US 11,789 dollars [US 8326 dollars-US 16,001 dollars] for infliximab in one, and US 16,665 dollars [US 10,329 dollars-US 25,690 dollars] for etanercept vs US 13,959 dollars [US 10,216 dollars-US 18,168 dollars] for infliximab in the other). CONCLUSION: These results suggest that costs of RA-related care during the first year of therapy may be lower among RA patients aged > or =65 years receiving etanercept versus infliximab, a difference attributable primarily to lower costs of drug acquisition. | |
16987681 | Expression of CXCR-1 and CXCR-2 chemokine receptors on synovial neutrophils in inflammator | 2006 Dec | OBJECTIVE: To analyze the CXCR-1 and CXCR-2 chemokine receptor expression on peripheral blood neutrophils (PBN) and synovial fluid neutrophils (SFN) of patients with rheumatoid arthritis (RA) and Behçet's disease (BD) (characterized by erosive and non-erosive arthritis, respectively), and to compare them with those of patients with osteoarthritis (OA). METHODS: We used flow cytometry to investigate the expression of CXCR-1 and CXCR-2 chemokine receptors on PBN and SFN of fifty-five (22 RA, 22 BD and 11 OA) age and sex-matched patients. RESULTS: In respect to chemokine receptor expression on neutrophils isolated from patients with RA, mean fluorescein intensity (MFI) of CXCR-1 chemokine receptors on PBN from active and inactive RA patients, and SFN from patients with RA were 151 (90-395), 129 (81-539) and 136 (64-220), respectively, and there were not statistically significant difference each other. But MFI of CXCR-2 chemokine receptors on SFN of patients with RA was 18 (10-32), and significantly higher than PBN of active and inactive RA patients (MFI: 10 (6-15) and 12 (7-16), P=0.002 and 0.037, respectively). In respect to chemokine receptor expression on neutrophils isolated from patients with BD, MFI of CXCR-1 chemokine receptors on PBN of active BD patients was 245 (97-844), and higher than PBN of active RA patients and SFN of BD patients (MFI: 151 (90-395) and 134 (61-231), P=0.047 and 0.017, respectively). MFI of CXCR-2 chemokine receptors on PBN of active and inactive BD patients, and SFN of patients BD were 10 (6-14), 10 (2-16), and 12 (8-24), respectively, there were not statistically significant difference each other. MFI of CXCR-1 chemokine receptors on SFN from patients with RA, BD, and OA were 136 (64-220), 134 (61-231), and 114 (60-180), respectively, and there was no difference between the study groups. MFI of CXCR-2 chemokine receptors on SFN of patients with RA was 18 (10-32), and higher than patients with BD and OA (MFI: 12 (8-24) and 11 (9-18), P=0.037 and 0.005, respectively), though there was no difference between last two groups. CONCLUSION: Our study points that CXCR-1 and CXCR-2 chemokine receptors of SFN may have diverse functions in the course of inflammatory arthritides. These results indicate that CXCR-2 chemokine receptor might play more critical role in long lasting accumulation of neutrophils within the synovial fluid of patients with RA. | |
16570441 | [Clinical observation on treatment of rheumatoid arthritis with cake-separated mild moxibu | 2006 Mar | OBJECTIVE: To observe the effect-increasing action of cake-separated mild moxibustion on rheumatoid arthritis (RA), and to probe a new method for RA. METHODS: Sixty cases were randomly divided into 2 groups. The control group (n=30) were treated with oral administration of methotrexate (MTX) as basic treatment, and non-steroid anti-inflammatory agents (NSAIDs) according to conditions of the patient. The treatment group (n=30) were treated with the same treatment as the control group, and Fuzi case-separated moxibustion at Guanyuan (CV 4) and Zusanli (ST 36) was added. They were treated for 3 months. RESULTS: After treatment of 3 months, the total effective rate was 83.3% in the treatment group, which was higher than 60.0% in the control group (P < 0.05); there were significant differences before and after treatment in all indexes in the two groups (P < 0.05 or P < 0.01); the ratio of the patients who completely withdrew NSAIDs in the treatment group was significantly higher than that in the control group (P < 0.05); the rate of adverse reaction in the treatment group was significantly lower than that in the control group (P < 0.05). CONCLUSION: Fuzi cake-separated mild moxibustion can increase clinical therapeutic effect on RA and reduce dosage of NSAIDs. | |
15598707 | The influence of previous and concomitant leflunomide on the efficacy and safety of inflix | 2005 Apr | OBJECTIVE: To investigate the influence of previous and concomitant leflunomide on the efficacy and safety of infliximab therapy in rheumatoid arthritis (RA) and to compare it to infliximab in combination with other disease-modifying anti-rheumatic drugs. METHODS: RA patients starting infliximab therapy were prospectively followed from January 2000. Every 3 months data were collected regarding disease activity (DAS28), adverse events and treatment changes. In the primary analyses all patients were classified into a leflunomide group (LEF group) if they had used leflunomide during infliximab therapy or within 6 months prior to starting infliximab therapy, the latter because of the long half-life of leflunomide. All other patients were considered as controls (non-LEF group). Secondary drug survival analyses were performed with the LEF group consisting only of patients on active leflunomide at the start of infliximab (active LEF group). RESULTS: A total of 162 RA patients started infliximab therapy (57 in the LEF group, 105 in the non-LEF group). No statistically significant differences in baseline characteristics were observed between the groups. Maximum follow-up time was 46 months for both groups. No differences in drug survival, disease activity or adverse events were observed between the groups. In both groups an increase in patients positive for antinuclear antibodies (ANA) was seen. ANA positivity at start did not predict DAS28 or the occurrence of adverse events. Secondary drug survival analyses showed no differences between the active LEF group and the non-LEF group. CONCLUSION: The results indicate that the administration of infliximab after or simultaneously with leflunomide is safe and efficacious in RA patients. | |
15385947 | Cardiovascular risk and COX-2 inhibition in rheumatological practice. | 2005 Jan | The use of specific COX-2 inhibitors in place of standard nonsteroidals for the treatment of arthritis appears to reduce the risk of serious gastrointestinal toxicity in this group of patients. However, the role played by these inhibitors in the generation or exacerbation of ischaemic cardiovascular disease is less clear. Clinical studies demonstrate that hypertension can be induced or aggravated by COX-2 inhibitors to a degree similar to that which occurs with standard nonsteroidals. Endothelial dysfunction, an indicator of cardiac ischaemia, may also be exacerbated by specific COX-2 inhibition and there is much debate as to whether these changes lead to an absolute increase in ischaemic cardiac events. These effects on cardiovascular risk factors appear all the more important in patients with rheumatoid arthritis where there is an increase in the incidence of ischaemic heart disease. Here we review the available data on COX-2 inhibition and cardiovascular disease and conclude that all patients who started these agents should have a careful assessment and modification of any cardiovascular risk factors. | |
17455718 | [Impression cytology in patients with dry eye syndrome and various rheumatic diseases]. | 2006 | PURPOSE: The aim of this study was to evaluate the cytological changes of bulbar conjunctiva in patients with various rheumatic diseases and dry eye syndrome. MATERIAL AND METHODS: 60 patients with rheumatoid arthritis (RA), systemic scleroderma (SScl), primary Sjbgren syndrome (pSS), systemic lupus erythematosus (SLE) and dry eye syndrome were studied. The ocular examination consisted of Schirmer I, break- up time of tear film (BUT), fluorescein and lissamine green staining and impression cytology of bulbar conjunctiva. RESULTS AND CONCLUSIONS: The morphological alternations of bulbar conjunctiva seen in impression cytology specimens correlated with clinical signs of dry eye syndrome. | |
16079993 | Hand disability and related variables in patients with rheumatoid arthritis. | 2006 Apr | OBJECTIVE: To carry out a cross-sectional study of patients with rheumatoid arthritis (RA) for hand disability, articular damage and to define their relation with demographic, laboratory and clinical parameters. METHODS: The study included 105 RA patients with a mean age of 49.4 years. Demographic parameters of the patients were recorded. Clinical parameters including disease duration, duration of morning stiffness, pain assessed by visual analog scale, Ritchie Articular Index, grip strength, lateral, tip and three-fingered pinch, and laboratory parameters comprising C-reactive protein, erythrocyte sedimentation rate and rheumatoid factor were evaluated in all patients. The Rheumatoid Arthritis Articular Damage (RAAD) score was used to assess the irreversible articular damage and deformities of the hand. Hand disability was assessed by the special hand disability index of Standford Health Assessment Questionnaire (HAQ). RESULTS: Hand disabilities of various levels were detected in 81% of the patients. Disease duration, grip strength, pinch measurements, clinical and laboratory activity parameters were strongly correlated with hand disability (p<0.01). Hand disability was more related to disease activity parameters than articular damage (p<0.01 and p<0.05, respectively). Grip strength and pinch measurements were the most related parameters with hand disability. The disability scores were significantly higher in female patients (p<0.01). The RAAD score was correlated with disease duration and grip strength (p<0.01). The clinical and laboratory parameters and seropositivity were not correlated with articular damage assessed by RAAD score (p>0.05). CONCLUSION: Our data suggest that grip strength and pinch measurements seem to be the most related variables with hand disability and articular damage. Therefore, grip strength and pinch measurement should be included in the evaluation and follow-up of the patients with RA in hand rehabilitation units. | |
16142851 | Low creatinine clearance, glucocorticoid treatment, rheumatoid arthritis--different etiolo | 2005 Sep | Low D-hormone syndrome, a disorder related to low creatinine clearance (CrCl), is associated with a roughly 4-fold increase in risk for falls. Known conditions leading to low D-hormone syndrome are CrCl < 65 ml/min, drug interactions, and chronic inflammatory diseases. This article reviews recent studies showing that treatment with D-hormone analogs, such as alfacalcidol, can reduce the frequency of falls in patients with low D-hormone syndrome. | |
17121488 | Monitoring outcomes of arthritis and longitudinal data collection using patient questionna | 2006 | Though quantitative data might lead to improved information for clinical decisions, at the present time decisions in routine rheumatology practice generally are based largely on qualitative impressions, rather than on data. Patient questionnaires are readily accessible tools that the rheumatologist can use to go beyond impressions and to institute evidence-based guidelines appropriate to his or her own patient population and practice style. The Health Assessment Questionnaire (HAQ) and its derivatives have been shown to be the best predictors of functional and work disability, costs, joint replacement surgery, and mortality. Such questionnaires are at least as good as joint counts, radiographs, and laboratory tests in predicting these outcomes. Every encounter of a patient with a rheumatologist provides an opportunity to collect data. Based on experience with the Brooklyn Outcomes of Arthritis Registry Database, the author advocates distributing a waiting-room questionnaire to every patient who comes for an office visit. Potential benefits of recording questionnaire-based information include identifying trends or important changes in a patient's pain or physical function, providing a baseline for success with various treatment strategies for conditions of the rheumatologist's own practice, allowing patients an opportunity to express concerns, encouraging patients to disclose information they may feel is too minor to mention, and providing control data for research studies. A short questionnaire designed specifically for clinical, rather than research, use does not create a burden for office staff. Consistent use of patient questionnaires and systematic storage of the information gained can help document, track, and improve patient care in routine rheumatology practice. |
