Development of semiquantitative ultrasound scoring system to assess cartilage in rheumatoid arthritis.

OBJECTIVES: To develop and test the reliability of a new semiquantitative scoring system for the assessment of cartilage changes by ultrasound in a web-based exercise as well as a patient exercise of patients with RA. METHODS: A taskforce of the Outcome Measures in Rheumatology Ultrasound Working Group performed a systematic literature review on the US assessment of cartilage in RA, followed by a Delphi survey on cartilage changes and a new semiquantitative US scoring system, and finally a web-based exercise as well as a patient exercise. For the web-based exercise, taskforce members scored a dataset of anonymized static images of MCP joints in RA patients and healthy controls, which also contained duplicate images. Subsequently, 12 taskforce members used the same US to score cartilage in MCP and proximal interphalangeal joints of six patients with RA in in a patient reliability exercise. Percentage agreement and prevalence of lesions were calculated, as intrareader reliability was assessed by weighted kappa and interreader reliability by Light's kappa. RESULTS: The three-grade semiquantitative scoring system demonstrated excellent intrareader reliability (kappa: 0.87 and 0.83) in the web-based exercise and the patient exercise, respectively. Interreader reliability was good in the web-based exercise (kappa: 0.64) and moderate (kappa: 0.48) in the patient exercise. CONCLUSION: Our study demonstrates that ultrasound is a reliable tool for evaluating cartilage changes in the MCP joints of patients with RA and supports further development of a new reliable semiquantitative ultrasound scoring system for evaluating cartilage involvement in RA.

Common atherosclerosis genetic risk factors and subclinical atherosclerosis in rheumatoid arthritis: the relevance of disease duration.

Rheumatoid arthritis (RA) is a common systemic autoimmune disease characterized by increased cardiovascular morbidity. Several previous studies assessed associations between common atherosclerotic genetic risk factors and subclinical atherosclerosis (SA) in RA patients, yet most of them gave negative results. We undertook a cross-sectional study to evaluate the association between previously reported SNPs and subclinical atherosclerosis in a cohort of Polish RA patients. 29 SNPs associated with atherosclerosis in general population were genotyped in 289 RA patients: 116 patients with SA (increased carotid intima-media thickness and/or presence of carotid plaque) and 173 patients without SA. To assess the cumulative effect of SNPs we calculated 3 weighted genetic risk scores: GRSIMT, GRSCP and GRSCAD, comprising intima-media thickness-associated SNPs, carotid plaque-associated SNPs and coronary artery disease-associated SNPs, respectively. None of the SNPs showed a significant association with SA. However, we found an association between SA and GRSIMT. Interestingly, this association was limited to patients with short disease duration (P = 0.00004 vs. P > 0.5, for comparison of GRSIMT among patients within the 1st quartile of disease duration vs. others, respectively). Patients within the 1st quartile of disease duration were more frequently disease modifying anti-rheumatic drugs (DMARDs)-naïve and less frequently treated with biologics. Our study suggests that in patients with early RA subclinical atherosclerosis may be driven by similar genetic factors as in general population, while in long-lasting disease, the role common genetic risk factors may decrease. Possibly, this effect may be due to the influence of DMARDs.

Value of multilocus genetic risk score for atrial fibrillation in end-stage kidney disease patients in a Polish population.

Genetic factors play a key role in the pathogenesis of atrial fibrillation (AF). We would like to establish an association between previously described single-nucleotide polymorphisms (SNPs) and AF in haemodialysed patients with end-stage kidney disease (ESKD-HD) as well as to assess the cumulative effect of all genotyped SNPs on AF risk. Sixteen SNPs were genotyped in 113 patients with AF-ESKD-HD and in 157 controls: without AF (NAF) and with ESKD-HD. The distribution of the risk alleles was compared in both groups and between different sub-phenotypes. The multilocus genetic risk score (GRS) was calculated to estimate the cumulative risk conferred by all SNPs. Several loci showed a trend toward an association with permanent AF (perm-AF): CAV1, Cx40 and PITX2. However, GRS was significantly higher in the AF and perm-AF groups, as compared to NAF. Three of the tested variables were independently associated with AF: male sex, history of myocardial infarction (MI) and GRS. The GRS, which combined 13 previously described SNPs, showed a significant and independent association with AF in a Polish population of patients with ESKD-HD and concomitant AF. Further studies on larger groups of patients are needed to confirm the associations.

Ultrasonography versus magnetic resonance imaging in detecting and grading common extensor tendon tear in chronic lateral epicondylitis.

OBJECTIVES: To investigate the diagnostic performance and reliability of ultrasonography (US) in detecting and grading common extensor tendon (CET) tear in patients with chronic lateral epicondylitis (LE), using magnetic resonance imaging (MRI) as the reference standard. MATERIALS AND METHODS: The study comprised fifty-eight chronic LE patients. Each patient underwent US and MRI. CET status was classified as: high-grade tear (≥50% thickness), low-grade tear (<50% thickness), suspected tear (possible but not evident tear), no tear. Additionally, the following dichotomous scale was used: confirmed or unconfirmed CET tear. Relative US parameters (versus MRI) for detecting CET tear included: sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy. The agreement between US and MRI findings was measured using the weighted Cohen kappa coefficient (κ). RESULTS: US showed moderate agreement with MRI in detecting and grading CET tear (κ = 0.49). Sensitivity, specificity, and accuracy in CET tear detecting by US were 64.52%, 85.19%, and 72.73%, respectively. PPV and NPV of US were 83.33% and 67.65%, respectively. No patient with unconfirmed CET tear on US had high-grade CET tear on MRI. CONCLUSION: Ultrasonography is a valuable imaging modality that can be used as a screening tool to exclude high-grade CET tear in chronic LE patients. Once a tear is evident on US, MRI should be considered to assess precisely the extent of tendon injury.

The association between 38 previously reported polymorphisms and psoriasis in a Polish population: High predicative accuracy of a genetic risk score combining 16 loci.

OBJECTIVES: To confirm the association of previously discovered psoriasis (Ps) risk loci with the disease in a Polish population and to create predictive models based on the combination of these single nucleotide polymorphisms (SNPs). MATERIAL AND METHODS: Thirty-eight SNPs were genotyped in 480 Ps patients and 490 controls. Alleles distributions were compared between patients and controls, as well as between different Ps sub-phenotypes. The genetic risk score (GRS) was calculated to assess the cumulative risk conferred by multiple loci. RESULTS: We confirmed associations of several loci with Ps: HLA-C, REL, IL12B, TRIM39/RPP21, POU5F1, MICA. The analysis of ROC curves showed that GRS combining 16 SNPs at least nominally (uncorrected P<0.05) associated with Ps (GRS-N) had significantly better discriminative power than GRS combining SNPs associated with Ps after the Bonferroni correction (AUC 0.776 vs. 0.750, P = 1 x 10-4) or HLA-C (AUC 0.776 vs. 0.694, P<1 x 10-5). On the other hand, adding additional SNPs to the model did not improve its discriminatory ability (AUC 0.782 for GRS combining all SNPs, P>0.05). In order to assess the total risk conferred by GRS-N, we calculated ORs according to GRS-N quartile - the Ps OR for top vs. bottom GRS-N quartiles was 12.29 (P<1 x 10-6). The analysis of different Ps sub-phenotypes showed an association of GRS-N with age of onset and family history of Ps. CONCLUSIONS: We confirmed the association of Ps with several previously identified genetic risk factors in a Polish population. We found that a GRS combining 16 SNPs at least nominally associated with Ps had a significantly better discriminatory ability than HLA-C or GRS combining SNPs associated with Ps after the Bonferroni correction. In contrast, adding additional SNPs to GRS did not increase significantly the discriminative power.

High Efficacy of Methotrexate in Patients with Recurrent Idiopathic Acute Anterior Uveitis: a Prospective Study.

To evaluate prospectively the efficacy of methotrexate (MTX) in the treatment of recurrent idiopathic acute anterior uveitis (RIAAU). Nineteen out of 22 RIAAU patients completed the study (two patients withdrew their consent shortly after study initiation, one patient discontinued after 4 weeks because of the adverse effects). All patients were treated with MTX in a starting dose of 15 mg/week, increased to target dose of 25 mg/week after 4 weeks. In patients taking systemic corticosteroids (CS) the dose was gradually tapered (by 2.5 mg every week) until discontinuation. The mean follow-up period was 3.3 years (19-59 months). Sixteen patients (84 %) remained flare-free on MTX therapy. In the remaining three patients the mean interval between flares increased from 4.8 to 18.3 months. Systemic CS were tapered off in all patients. The number of acute anterior uveitis flares in the whole cohort decreased from 2.12 to 0.11/patient-year (p < 0.0001). All flares observed on MTX therapy occurred in HLA-B27-positive patients. MTX dosed at 25 mg/week is highly effective in the treatment of RIAAU.

An OMERACT reliability exercise of inflammatory and structural abnormalities in patients with knee osteoarthritis using ultrasound assessment.

OBJECTIVE: To assess whether ultrasonography (US) is reliable for the evaluation of inflammatory and structural abnormalities in patients with knee osteoarthritis (OA). METHODS: Thirteen patients with early knee OA were examined by 11 experienced sonographers during 2 days. Dichotomous and semiquantitative scoring was performed on synovitis characteristics in various aspects of the knee joint. Semiquantitative scoring was done of osteophytes at the medial and lateral femorotibial joint space or cartilage damage of the trochlea and on medial meniscal damage bilaterally. Intra- and interobserver reliability were computed by use of unweighted and weighted κ coefficients. RESULTS: Intra- and interobserver reliability scores were moderate to good for synovitis (mean κ 0.67 and 0.52, respectively) as well as moderate to good for the global synovitis (0.70 and 0.50, respectively). Mean intra- and interobserver reliability κ for cartilage damage, medial meniscal damage and osteophytes ranged from fair to good (0.55 and 0.34, 0.75 and 0.56, 0.73 and 0.60, respectively). CONCLUSIONS: Using a standardised protocol, dichotomous and semiquantitative US scoring of pathological changes in knee OA can be reliable.

Treat-to-target therapy does not prevent excessive progression of carotid intima media thickness during the first year of therapy in early rheumatoid arthritis.

INTRODUCTION: The aim of the study was to investigate the presence of subclinical atherosclerosis and predictors of change in carotid intima-media measures in early rheumatoid arthritis patients (eRA) as compared to chronic RA patients and patients without arthritis. MATERIAL AND METHODS: Fifty-five consecutive eRA patients were assessed at the time of diagnosis and after 1 year of therapy. Fifty-five sex- and age-matched chronic RA patients and 29 patients without inflammatory disease were used as controls. Carotid artery intima-media thickness (CIMT) and carotid plaques were measured at baseline and after follow-up. In eRA patients ultrasound assessment of hand joints was performed before and after treatment. Carotid artery intima-media thickness was assessed again after 2 years in 44 eRA patients. RESULTS: Carotid artery intima-media thickness progression after 1 year of therapy was higher in eRA patients compared to both control groups (p = 0.017) and correlated with symptoms duration (p = 0.017) and DMARD monotherapy (p = 0.015). Ultrasound progression of hand joint erosions was associated with longer symptoms duration (p = 0.006). After 2 years of observation CIMT progression was similar in all examined groups. CONCLUSIONS: We observed rapid CIMT progression during the first year of RA therapy. Longer symptoms duration and less aggressive therapy were associated with CIMT increase.

2015 Recommendations for the management of polymyalgia rheumatica: a European League Against Rheumatism/American College of Rheumatology collaborative initiative.

Therapy for polymyalgia rheumatica (PMR) varies widely in clinical practice as international recommendations for PMR treatment are not currently available. In this paper, we report the 2015 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) recommendations for the management of PMR. We used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology as a framework for the project. Accordingly, the direction and strength of the recommendations are based on the quality of evidence, the balance between desirable and undesirable effects, patients' and clinicians' values and preferences, and resource use. Eight overarching principles and nine specific recommendations were developed covering several aspects of PMR, including basic and follow-up investigations of patients under treatment, risk factor assessment, medical access for patients and specialist referral, treatment strategies such as initial glucocorticoid (GC) doses and subsequent tapering regimens, use of intramuscular GCs and disease modifying anti-rheumatic drugs (DMARDs), as well as the roles of non-steroidal anti-rheumatic drugs and non-pharmacological interventions. These recommendations will inform primary, secondary and tertiary care physicians about an international consensus on the management of PMR. These recommendations should serve to inform clinicians about best practices in the care of patients with PMR.

Systemic lupus erythematosus: the influence of disease-related and classical risk factors on intima media thickness and prevalence of atherosclerotic plaques--a preliminary report. Beneficial effect of immunosuppressive treatment on carotid intima media thickness.

OBJECTIVE: The risk of cardiovascular disease is increased in systemic lupus erythematosus (SLE). A meta-analysis showed increased carotid intima media thickness (IMT) in SLE. The aim of this study was to assess the influence of different SLE characteristics and treatment regimens on IMT and atherosclerotic plaques. METHODS AND RESULTS: One hundred and three SLE patients and 95 age- and sex-matched control subjects were included in the study. MT was measured in the common carotid arteries bilaterally. Common carotid arteries, internal carotid arteries and superficial femoral arteries were also screened for the presence of plaques. The presence of plaques was correlated with age (P = 0.00002), male sex (P = 0.034), Framingham 10-year risk score (P < 1 x 10(-6)), SLE duration (P = 0.00006), lack of immunologic disorder (P = 0.0014) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (P = 0.049). IMT was associated with SLE duration (P = 0.002), body mass index (P = 0.026), Framingham 10-year risk score (P < 0.001), total cholesterol concentration (P = 0.002), LDL cholesterol concentration (P = 0.007), SLICC/ACR (P = 0.035), hypertension (P = 0.002), immunologic disorder (P = 0.00008) and discontinuous treatment with immunosuppressive drugs (P = 0.043). CONCLUSIONS: We found a correlation between atherosclerosis and several classical cardiovascular risk factors and disease-related factors. A beneficial effect of continuous immunosuppressive treatment on IMT suggests that appropriate disease control with steroid-sparing agents may protect against atherosclerosis in SLE patients.

Methotrexate, Cyclosporine A, and Biologics Protect against Atherosclerosis in Rheumatoid Arthritis.

INTRODUCTION: The risk of cardiovascular disease is increased in rheumatoid arthritis (RA). A meta-analysis showed increased intima media thickness (IMT) in RA. It has been shown that disease modifying antirheumatic drugs (DMARDs) may influence the progression of atherosclerosis. However, it was suggested that biologics may be more efficient than other DMARDs (including methotrexate--MTX) in protecting against atherosclerosis. OBJECTIVES: The aim of this study was to assess the influence of different RA characteristics and treatment regimens on IMT and atherosclerotic plaques. PATIENTS AND METHODS: 317 RA patients and 111 controls were included in the study. IMT was measured in carotid (CIMT) and femoral (FIMT) arteries. Arteries were screened for the presence of plaques. RESULTS: CIMT, FIMT, and prevalence of plaques were lower in patients treated with methotrexate (MTX) ≥ 20 mg/wk, cyclosporine (CsA), or biologics than in patients treated with lower doses of MTX and other disease modifying antirheumatic drugs. No differences in IMT between patients treated with MTX ≥ 20 mg/wk, biologics, or CsA were found. CONCLUSIONS: We found a beneficial effect of MTX ≥ 20 mg/wk, biologics, and CsA on atherosclerosis. We do not confirm a stronger influence of biologics on IMT compared with therapeutic doses of MTX.

Evaluation of the effectiveness of platelet rich plasma in treatment of chronic pes anserinus pain syndrome.

BACKGROUND: Enthesopathy-associated pain does not only occur in athletes but also in persons of average daily activity levels. Repetitive microtrauma within the pes anserinus may lead to chronic inflammation and later result in development of degenerative changes in this region. It is commonly believed that this condition is caused by chronic bursitis of the pes anserinus. However, imaging studies have confirmed that as the underlying cause of complaints only in a small percentage of cases. MATERIAL AND METHODS: Between 2011 and 2012, a total of 33 patients with chronic pain in the pes anserinus were treated with platelet rich plasma at the Department of Orthopaedics, Military Institute of Medicine. All patients received 10 mL of autologous platelet rich plasma into the painful region. The effectiveness of platelet rich plasma was evaluated by comparing pre-treatment results and those obtained at 3 and 6 months following the therapy. Pain intensity was evaluated before and after treatment using a VAS scale and the modified Likert scale. RESULTS: A total of 28 patients (84.8% of the study participants) demon strated total or near-total pain relief within 6 months following treatment. CONCLUSIONS: 1. Pes anserinus pain syndrome is a relatively com mon condition in overweight and obese women over 50 years of age. 2. Our study demonstrated that a greater intensity of degenerative changes of the knee joint was ac companied by more severe pain in the pes anserinus area. 3. Platelet rich plasma is an effective treatment for pes anserinus pain. It produces pain relief and thus significantly improves the quality of life. 4. The response to platelet-derived growth factors was poorer in advanced degenerative knee joint disease. 5. Our treatment is safe; plasma administered to patients was obtained from their own peripheral blood and did not constitute a source of infection with viral hepatitis or HIV.

2012 provisional classification criteria for polymyalgia rheumatica: a European League Against Rheumatism/American College of Rheumatology collaborative initiative.

The objective of this study was to develop EULAR/ACR classification criteria for polymyalgia rheumatica (PMR). Candidate criteria were evaluated in a 6-month prospective cohort study of 125 patients with new onset PMR and 169 non-PMR comparison subjects with conditions mimicking PMR. A scoring algorithm was developed based on morning stiffness >45 minutes (2 points), hip pain/limited range of motion (1 point), absence of RF and/or ACPA (2 points), and absence of peripheral joint pain (1 point). A score ≥4 had 68% sensitivity and 78% specificity for discriminating all comparison subjects from PMR. The specificity was higher (88%) for discriminating shoulder conditions from PMR and lower (65%) for discriminating RA from PMR. Adding ultrasound, a score ≥5 had increased sensitivity to 66% and specificity to 81%. According to these provisional classification criteria, patients ≥50 years old presenting with bilateral shoulder pain, not better explained by an alternative pathology, can be classified as having PMR in the presence of morning stiffness>45 minutes, elevated CRP and/or ESR and new hip pain. These criteria are not meant for diagnostic purposes.

According to these provisional classification criteria, patients ≥50 years old presenting with bilateral shoulder pain, not better explained by an alternative pathology, can be classified as having PMR in the presence of morning stiffness >45 minutes, elevated C-reactive protein and/or erythrocyte sedimentation rate, and new hip pain. These criteria are not meant for diagnostic purposes.

Patient-reported outcomes in polymyalgia rheumatica.

OBJECTIVE: To prospectively evaluate the disease course and the performance of clinical, patient-reported outcome (PRO) and musculoskeletal ultrasound measures in patients with polymyalgia rheumatica (PMR). METHODS: The study population included 85 patients with new-onset PMR who were initially treated with prednisone equivalent dose of 15 mg daily tapered gradually, and followed for 26 weeks. Data collection included physical examination findings, laboratory measures of acute-phase reactants, and PRO measures. Ultrasound evaluation was performed at baseline and Week 26 to assess for features previously reported to be associated with PMR. Response to corticosteroid treatment was defined as 70% improvement in PMR on visual analog scale (VAS). RESULTS: At baseline, 77% had hip pain in addition to shoulder pain and 100% had abnormal C-reactive protein or erythrocyte sedimentation rate. On ultrasound, 84% had shoulder findings and 32% had both shoulder and hip findings. Response to corticosteroid treatment occurred in 73% of patients by Week 4 and was highly correlated with percentage improvement in other VAS measures. Presence of ultrasound findings at baseline predicted response to corticosteroids at 4 weeks. Factor analysis revealed 6 domains that sufficiently represented all the outcome measures: PMR-related pain and physical function, an elevated inflammatory marker, hip pain, global pain, mental function, and morning stiffness. CONCLUSION: PRO measures and inflammatory markers performed well in assessing disease activity in patients with PMR. A minimum set of outcome measures consisting of PRO measures of pain and function and an inflammatory marker should be used in practice and in clinical trials in PMR.

Practice of ultrasound-guided arthrocentesis and joint injection, including training and implementation, in Europe: results of a survey of experts and scientific societies.

OBJECTIVES: To document the practice and training opportunities of US-guided arthrocentesis and joint injection (UGAJ) among rheumatologists in the member countries of the European League Against Rheumatism (EULAR). METHODS: An English-language questionnaire, containing questions on demographics, clinical and practical aspects of UGAJ, training options in UGAJ for rheumatologists, UGAJ education in the rheumatology training curriculum and other structured education programmes in UGAJ was sent to three different groups: (i) all national rheumatology societies of EULAR; (ii) all national societies of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB); and (iii) 22 senior rheumatologists involved in EULAR musculoskeletal US training from 14 European countries, who were also asked to circulate the questionnaire among relevant colleagues. RESULTS: Thirty-three (75%) of 44 countries responded to the questionnaire (61.3% of national rheumatology societies, 25% of the national US societies and 100% of expert ultrasonographers). In the majority of countries (85%) <10% of rheumatologists routinely perform UGAJ in clinical practice, while the remaining countries (15%) reported a rate of 10-50%. The percentage of rheumatologists receiving training in UGAJ was <10% in the majority (72.7%) of countries. CONCLUSION: The study highlights the relatively low prevalence of UGAJ as compared with the high (>80%) rate of rheumatologists performing conventional joint injection in most of the surveyed countries. The reported variations in practice and the lack of available structured training programmes for trainees in most countries indicates the need for standardization in areas including training guidelines.

[Pharmacological treatment of recurrent idiopathic anterior uveitis]. / Leczenie farmakologiczne chorych na nawrotowe idiopatyczne zapalenie przedniego odcinka blony naczyniowej oka.

Recurrent anterior uveitis (AU) is an autoimmune disease that in 20% of patients leads to severe visual loss or blindness, thereby a severe disability and significant quality of life impairment. That is why, it is important to conduct a long term treatment after an acute phase of the disease, to keep the remission as long as possible. Up to 50% of patients with recurrent AU have no additional symptoms of systemic disease. This situation, classified as idiopathic AU (IAU), causes a lot of problems when a therapeutic strategy has to be chosen. Nevertheless, IAU is considered to be a first symptom of spondylarthropathy (SpA), even several dozen years prior to other typical manifestations of SpA. There have been published few papers concerning only small groups of patients with IAU, treated with disease modifying anti-rheumatic drugs. The authors present the recommendations for systemic treatment of IAU, based on their own clinical experience, and systematic review of the literature.

[Leflunomide as a second choice treatment in patients with rheumatoid arthritis]. / Leflunomid jako lek drugiego wyboru u chorych na reumatoidalne zapalenie stawów.

UNLABELLED: Leflunomide is a relatively new disease modifying antirheumatic drug (DMARD) and a number of studies evaluating its effectiveness and safety in daily medical practice is limited. THE AIM OF THE STUDY: Evaluation of effectiveness and safety of leflunomide treatment in patients with active rheumatoid arthritis in whom methotrexate was ineffective or contraindicated. MATERIAL AND METHODS: Eighty one patients (66 women and 15 men) with RA diagnosed according to ARA (The American Rheumatism Association) criteria were included in the study. The mean age was 57.6+/-11.7 years and the mean disease duration was 7.7+/-7.1 years. The inclusion criteria were: disease activity according to DAS28 (Disease Activity Score)>3.2 and contraindications to methotrexate or ineffective methotrexate treatment for at least 3 months. At the beginning of the study 49 of patients were treated with methotrexate in weekly dose of 17+4.2mg and 32 were not treated with DMARDs. Oral glicocorticosteroids in stable doses of 5-15mg of prednisone were given to 66 (77.7%) of them. There was no statistically significant difference in radiological progression of the disease according to Steinbrocker's scale between groups (treated and not treated with methotrexate). Monotherapy with leflunomide was started with loading dose of 100mg for 3 days, and then 20mg daily. Combination therapy was introduced without loading dose. Evaluation was performed monthly and included: duration of morning stiffness, pain and disease activity according to VAS (visual-analogue) scale, the number of tender and swollen joints, blood count, ESR, CRP, aminotransferases activity, and the presence and intensity of adverse reactions. The results of treatment were evaluated after 5 months in 37 of patients and adverse reactions which happened until the end of 5th month were evaluated in all included patients. RESULTS: The mean DAS28 values improved exponentially during consecutive months and the difference between them was statistically significant. Adverse reactions during 5 months of treatment were observed in 36(44,4%) of patients and in 6(7,4%) of cases the treatment had to be stopped because of side effects. The frequency of adverse reactions was similar in monotherapy and combination therapy group. CONCLUSIONS: Leflunomide therapy can be effective in patients with active rheumatoid arthritis in whom methotrexate is contraindicated or insufficient. Combination of leflunomide with methotrexate is safe and does not increase the frequency of adverse reactions.

[Prevalence of cervical spine inflammatory changes in rheumatoid arthritis patients and the value of neurological examination in their diagnosis]. / Czestosc wystepowania zmian zapalnych w odcinku szyjnym kregoslupa u chorych na reumatoidalne zapalenie stawów i rola badania neurologicznego w ich diagnostyce.

The aim of the study was to evaluate prevalence of cervical spine inflammatory changes, especially atlantoaxial pathology, and their possible relation to subjective and objective neurological symptoms in rheumatoid arthritis patients. 100 patients (88 female and 12 male) aged 23 to 85 (61.4 +/- 12.9), with the mean disease duration of 12.5 +/- 9.5 years were included in the study. According to radiological examination (lateral and antero-posterior X-ray of the cervical spine) supplemented by MR of the cervical spine or CT of the atlanto-axial joint in suspected cases, 26% of patients had only inflammation, next 15% of patients presented with instability of the atlanto-axial joint and 9% developed basilar invagination of the dens of axis. 18% of patients presented subaxial cervical instability. Neurological examitation was performed by independent neurologist in 99 patients, only 14 presented abnormalities suggesting cervical myelopathy. Two of them showed no patology of the cervical spine. Remaining patients presented: C1/C2 inflammation in 4 cases, anterior atlanto-axial subluxation (AAS) in two cases, basilar invagination in 4 cases and instability with medullary compression on lower cervical levels only--in two cases. There were 4 cases of coexisting C1/C2 changes with medullary compression due to discopathy and (in 3 of them) instability on lower cervical levels. In 6 cases surgical stabilisation was proposed (5 patients with basilar invagination and 1 patient with AAS and myelopathy). There was statistically significant correlation between symptoms (like: paraesthesiae, intermittent problems with hearing and seeing), neurological examination and degree of radiological damage of atlanto-axial joint. The authors concluded that careful medical history and neurological examination can be useful in making decision of further radiological diagnostic procedures of the cervical spine in rheumatoid arthritis.
