EULAR evidence based recommendations for the management of hand osteoarthritis: report of a Task Force of the EULAR Standing Committee for International Clinical Studies Including Therapeutics (ESCISIT).

OBJECTIVES: To develop evidence based recommendations for the management of hand osteoarthritis (OA). METHODS: The multidisciplinary guideline development group comprised 16 rheumatologists, one physiatrist, one orthopaedic surgeon, two allied health professionals, and one evidence based medicine expert, representing 15 different European countries. Each participant contributed up to 10 propositions describing key clinical points for management of hand OA. Final recommendations were agreed using a Delphi consensus approach. A systematic search of Medline, Embase, CINAHL, Science Citation Index, AMED, Cochrane Library, HTA, and NICE reports was used to identify the best available research evidence to support each proposition. Where possible, the effect size and number needed to treat were calculated for efficacy. Relative risk or odds ratio was estimated for safety, and incremental cost effectiveness ratio was used for cost effectiveness. The strength of recommendation was provided according to research evidence, clinical expertise, and perceived patient preference. RESULTS: Eleven key propositions involving 17 treatment modalities were generated through three Delphi rounds. Treatment topics included general considerations (for example, clinical features, risk factors, comorbidities), non-pharmacological (for example, education plus exercise, local heat, and splint), pharmacological (for example, paracetamol, NSAIDs, NSAIDs plus gastroprotective agents, COX-2 inhibitors, systemic slow acting disease modifying drugs, intra-articular corticosteroids), and surgery. Of 17 treatment modalities, only six were supported by research evidence (education plus exercise, NSAIDs, COX-2 inhibitors, topical NSAIDs, topical capsaicin, and chondroitin sulphate). Others were supported either by evidence extrapolated from studies of OA affecting other joint sites or by expert opinion. Strength of recommendation varied according to level of evidence, benefits and harms/costs of the treatment, and clinical expertise. CONCLUSION: Eleven key recommendations for treatment of hand OA were developed using a combination of research based evidence and expert consensus. The evidence was evaluated and the strength of recommendation was provided.

Characterization of patients with an inadequate clinical outcome from osteoporosis therapy: the Observational Study of Severe Osteoporosis (OSSO).

BACKGROUND: Osteoporotic fractures remain a major public health problem. Currently available osteoporosis therapies significantly reduce the risk of fractures, but up to 50% of patients have an inadequate clinical outcome to therapy. AIM: To describe the clinical and quality of life (QOL) of a study population meeting a proposed definition of inadequate clinical outcome to osteoporosis therapy, recruited for the Observational Study of Severe Osteoporosis (OSSO). DESIGN: Cross-sectional, observational study. METHODS: Post-menopausal women with osteoporosis (n = 2314) were divided into Group 1 (those who had previously experienced a fragility fracture despite osteoporosis drug therapy for at least 12 months) (n = 1309, 57%), or Group 2 (those who had previously discontinued osteoporosis drug therapy due to non-compliance or side-effects) (n = 1005; 43%). Baseline clinical characteristics, quality of life (QOL) and osteoporosis/falls risk factors were analysed. RESULTS: The overall population had low BMD (mean +/- SD T-score at lumbar spine -3.1 +/- 1.1), and risk factors for fracture such as previous fractures (67.8%), family history (15.1%), and prolonged glucocorticoid use (17.5%). QOL was poor: total QUALEFFO and EQ-5D scores were 46.8 +/- 18.7, and 0.50 +/- 0.33, respectively. Patients in Group 1 had higher age and body mass index, fewer hours of exercise, more previous fragility fractures and falls, and poorer QOL scores. DISCUSSION: Our definition of inadequate clinical outcome from osteoporosis drug therapy identifies a severe osteoporosis cohort with poor QOL and increased fracture risk. Using such a definition may lead to earlier recognition of inadequate clinical outcome to osteoporosis therapy, and improved interventions and results.

[Infliximab (anti-TNF-alpha) treatment in patients with adult Still's disease. Experience in 2 cases].

Adult Still's disease is a systemic inflammatory disorder of unknown etiology. First-line treatment for Still's disease includes nonsteroidal anti-inflammatory drugs and corticosteroids. In refractory cases o when the dose of corticosteroid is unacceptably high, other disease modifying antirheumatic drugs have been used. But recent study showed the efficacy anti-TNF therapy in adult Sill's disease refractory to conventional therapy. We report a favourable response to infliximab in two patients who has proved resistant to conventional therapy.

Factors related to radiological damage in 61 Spaniards with early rheumatoid arthritis.

OBJECTIVE: To determine whether the presence of radiographic erosions at disease onset in patients with early rheumatoid arthritis (RA) is associated with clinical, serological, or genetic factors of poor outcome and whether patients with erosions only in the feet have a different pattern of presentation. METHODS: Sixty one patients with early RA (<6 months of evolution) were studied. Clinical evaluation and serological, radiological, and genetic studies were performed at disease onset and after one year. RESULTS: Forty one (67%) patients showed erosions in their hands or in their feet, or in both. Subjects with erosive RA had a higher number of swollen joints (SJN; 9 (SD 6) v. 6 (3), p=0.008), and rheumatoid factor (RF) positivity was more common (80% v. 50%, p<0.02) than those without erosions. Seven (17%) of the 41 patients in the group with erosions had erosions only in their feet. This group had a longer duration of morning stiffness (120 (60) v. 72 (52) min, p<0.005), better patient's global assessment of general health (34 (22) v. 57 (25), p< 0.05), and lower erythrocyte sedimentation rate (32 (22) v. 60 (30) mm/1st h, p <0.05) than the rest of the subjects with erosions, and none of them was in remission after one year. Remission after one year was related to a lack of cortical damage at onset and RF negativity. CONCLUSIONS: Radiological damage at disease onset is associated with a worse clinical presentation and RF positivity, which are markers of poor outcome. There is a subgroup of patients, with erosions only in their feet, whose clinical presentation is less aggressive. To identify these cases of early erosive RA, radiographs of the feet should be obtained routinely.

Soluble HLA class I antigens in serum and synovial fluid from patients with rheumatoid arthritis and other arthropathies.

OBJECTIVES: To investigate the presence of soluble HLA class I (s-HLA) antigens in serum and synovial fluid (SF) from a large cohort of rheumatic patients. METHODS: We studied clinical and analytical data and serum samples from 300 patients [122 patients with rheumatoid arthritis (RA), 38 with osteoarthritis or osteoporosis, 29 with seronegative spondyloarthropathies, 45 patients with other rheumatic diseases] and 66 healthy controls. In addition, we studied 25 paired samples of serum and SF from these groups of subjects. In RA patients, we examined whether the levels of s-HLA in serum and SF were related to the activity of the disease. RESULTS: The mean concentrations of s-HLA molecules in serum were slightly higher in RA patients (1.2 microg/ml) than in the other four groups (1.08, 1.01, 1.09 and 0.94 microg/ml respectively). We found no correlation between serum s-HLA levels and any variable of inflammatory disease activity in RA patients. s-HLA molecules were found in SF and at levels that correlated with those found in serum (P=0.04; r=0.4). Furthermore, s-HLA levels were higher in SF from patients with RA (1.3 microg/ml) or crystal-induced arthritis (0.98 microg/ml) than in SF from those with osteoarthritis (0.38 microg/ml) (P<0.05 and P<0.005 respectively), and these levels were correlated inversely and significantly with the score on the visual analogue scale of pain (P=0.02), the number of painful joints (P=0.05) and the level of C-reactive protein (P=0.03) in RA patients. CONCLUSIONS: This is the first report to demonstrate the presence of s-HLA molecules in SF at levels that correlate with serum levels. The mean levels of s-HLA molecules were significantly higher in SF from patients with RA and crystal-induced arthritis than in SF from cases of osteoarthritis, and correlated inversely with certain variables of disease activity in RA patients.

Pes anserinus tendino-bursitis: what are we talking about?

We studied the ultrasonographic (US) features of the pes anserinus insersion (PA) and subcutaneous medial knee fat in patients clinically diagnosed of pes anserinus tendino-bursitis (PATB) syndrome. Thirty seven consecutive patients with suspected PATB were clinically evaluated and their knees examined using a 7.5 MHz linear probe. In twenty-three patients with unilateral clinical PATB (group A) the painful knee was compared with their painless opposite knee. Six patients with bilateral clinical PATB (group B) were compared with 6 healthy controls (group C). All patients were women with radiographic knee osteoarthritis in 93% and body mass index > 27 in 75%. US pes anserinus tendinitis was found in one symptomatic knee and pes anserinus bursitis in two symptomatic knees and in one asymptomatic knee. No US signs of panniculitis were found in patients and controls. In conclusion, patients diagnosed of PATB syndrome in rheumatology rarely have US tendinitis or bursitis of the PA.

Class II MHC antigens in early rheumatoid arthritis in Bath (UK) and Madrid (Spain).

OBJECTIVE: A number of studies have indicated that rheumatoid arthritis (RA) is a less severe disease in Mediterranean countries than in Northern Europe. We investigated whether differences in the frequency of class II MHC antigens might contribute to this variation in disease severity. METHODS: Typing at HLA-DR and -DQ loci was carried out at low and high resolutions by polymerase chain reaction amplification in patients with early RA of less than 6 months' duration (68 patients in Madrid and 68 in Bath) and in control subjects (929 in Madrid and 226 in Bath). Only ethnic Spanish and British individuals were included as patients and controls. RESULTS: Shared epitope (SE) alleles represented 19.8 and 28.9% of the total number of class II MHC alleles in controls from Madrid and Bath respectively (P: = 0.00001), this difference being largely due to increased numbers of DRB1*0401 individuals in the British subjects (P: = 0.0000001). Analysis of the patients showed the expected increase in SE alleles when compared with their respective control groups (Madrid, 31.6 vs 19.8%; Bath, 42.6 vs 28. 9%). In Bath the SE was mainly encoded by HLA-DR4 alleles (74.1%), while in Madrid it was encoded almost equally by DR4 (51.1%) and DR1 (44.7%) alleles. The risk of developing RA in carriers of SE alleles was similar in the two cities (Bath, odds ratio 1.83, 95% confidence interval 1.23-2.78; Madrid, odds ratio 1.87, 95% confidence interval 1.25-2.77), and was largely accounted for by HLA-DRB1*0401 alleles. CONCLUSION: We conclude that rheumatoid patients in Bath differ from their Spanish counterparts in class II antigen expression and allele frequency. This may be explained partly by genetic differences between the control populations in the two centres, and may help to explain the greater incidence of more severe rheumatoid disease expression seen in RA patients in the UK.

Activity indices in rheumatoid arthritis.

OBJECTIVE: To determine which activity indices better correlate with assessor's (AGA) and patient's (PGA) global assessment of disease activity and to compare the improvement with American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) criteria and their association with PGA and AGA of overall improvement. METHODS: Seventy-five patients with rheumatoid arthritis (RA) were studied. Swollen and tender joints, morning stiffness, grip strength, pain, AGA, PGA, Health Assessment Questionnaire (HAQ) score, erythrocyte sedimentation rate (ESR), C-reactive protein (CPR), and hemoglobin were determined before and 6 months after treatment. Several activity indices were calculated: Disease Activity Score (DAS), DAS 3, DAS 28, DAS '28,' ACR > or = 20%, Mallya, Riel, IDA, and a modification of the Stoke index. RESULTS: All indices correlated with PGA and AGA before and after treatment (r > 0.38, p < 0.01), but better results were obtained with AGA than PGA. DAS, DAS 3, DAS 28, and modified Stoke had the best correlation with AGA (r > or = 0.77, p < 0.01). The indices that better detected the differences after treatment for AGA were DAS, DAS 3, DAS 28, and modified Stoke (r > or = -0.42, p < 0.01). The level of agreement between EULAR and ACR improvement classifications with both reduced and extensive joint counts was comparable and its association with PGA and AGA overall improvement was significant (p < 0.01). CONCLUSION: All activity indices correlated with PGA and AGA, although the best results were obtained with AGA. Although indices' correlations were similar, the DAS group and the modified Stoke seemed to be the most useful indices to measure disease activity in RA. The discriminating potential between ACR and EULAR improvement classification was comparable, as was the association with PGA and AGA overall improvement.

Increased plasma levels of homocysteine and other thiol compounds in rheumatoid arthritis women.

OBJECTIVES: Since moderate hyperhomocysteinemia is an independent risk factor for vascular disease and physiological thiol compounds mediate Cu2+- and Fe3+-dependent low-density lipoprotein (LDL) oxidation, we have studied the total plasma concentrations of thiol compounds including methionine as precursor of homocysteine in rheumatoid arthritis patients, in which the high mortality found is associated with cardiovascular disease. DESIGN AND METHODS: Thirty-eight women with rheumatoid arthritis and 25 age-matched control women were studied. Plasma was used to measure thiol compounds and amino acids by HPLC. RESULTS: Rheumatoid arthritis patients showed significantly higher levels than healthy controls of total plasma homocysteine (17.3 +/- 7.8 vs. 7.6 +/- 1.9; p <0.001), cysteine (293 +/- 61 vs. 201 +/- 45; p < 0.001), cysteinglycine (32.7 +/- 8.3 vs. 22.3 +/- 4.7; p < 0.001) and methionine (25 +/- 9 vs. 18 +/- 3; p < 0.01), whereas total glutathione levels were not increased (4.7 +/- 2.0 vs. 4.1 +/- 1.6). CONCLUSIONS: The increased levels of thiol compounds found in rheumatoid. arthritis patients may be implicated in the increased incidence of cardiovascular disease found in these patients by means of the toxic effect of homocysteine on endothelium and the increased susceptibility of LDL to oxidation by increased plasma amounts of thiol compounds such as cysteine.

Comparison of dexketoprofen trometamol and ketoprofen in the treatment of osteoarthritis of the knee.

Dexketoprofen, the active enantiomer of the racemic compound ketoprofen, is a new nonsteroidal antiinflammatory drug (NSAID) of the arylpropionate family. The efficacy and safety of dexketoprofen trometamol were compared with the equivalent enantiomeric dose of ketoprofen in a multicenter, randomized, double-blind 3-week trial of adult outpatients with pain due to osteoarthritis of the knee. After a washout period of 7-15 days, patients were randomly assigned to receive either dexketoprofen trometamol 25 mg tid (N = 89) or ketoprofen 50 mg tid (N = 94). Of the 183 patients enrolled, two were lost to follow-up. At the end of treatment (3 weeks), the main efficacy outcome measures were significantly better in the dexketoprofen trometamol group than in the ketoprofen group. In addition, overall physician assessment indicated that 75% of the dexketoprofen group had improved compared with 50% of the ketoprofen patients. There were fewer adverse events in the dexketoprofen treatment group, but the difference did not reach statistical significance. These results demonstrate that dexketoprofen trometamol 25 mg tid is more effective than ketoprofen 50 mg tid in short-term symptomatic treatment of knee osteoarthritis and suggest that the tolerability of dexketoprofen trometamol is more favorable than ketoprofen. Therefore, the substitution of dexketoprofen for racemic ketoprofen may be advantageous in clinical practice.

Soluble interleukin 6 (IL-6) receptor and IL-6 levels in serum and synovial fluid of patients with different arthropathies.

OBJECTIVE: We studied interleukin 6 (IL-6) and soluble IL-6 receptor (sIL-6R) in serum and synovial fluid (SF) to investigate their role in different arthropathies. METHODS: IL-6 was measured by ELISA and bioassay and sIL-6R by ELISA, in 210 sera and 73 SF samples from 49 patients with rheumatoid arthritis (RA), 20 crystal deposition disease, 17 osteoarthritis (OA), 24 with other inflammatory arthropathies, and 100 controls. In all patients, disease activity was assessed by erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP); in patients with RA and other arthropathies pain, tender and swollen joints, and Ritchie index were also evaluated. Total leukocyte count in SF was determined. RESULTS: There was good correlation between IL-6 ELISA and bioassay levels both in serum (r = 0.62, p = 0.0001) and in SF (r = 0.72, p = 0.0001). Serum IL-6 was detected only in patients with inflammatory arthritis and SF IL-6 was detected in all patient groups. Serum IL-6 correlated with swollen joints (r = 0.35, p = 0.05), ESR (r = 0.46, p = 0.001), and CRP (r = 0.46, p = 0.001) in RA; and with CRP (r = 0.89, p = 0.0001) in crystal deposition disease. SF IL-6 correlated with ESR (r = 0.54, p = 0.007) and CRP (r = 0.42, p = 0.04) in RA; with SF total leukocyte count (r = 0.61, p = 0.004) in crystal deposition disease; and with SF total leukocyte count (r = 0.61, p = 0.009) in OA. No correlations were found in the group with other inflammatory diseases. No correlations were found between sIL-6R and IL-6 or between sIL-6R and disease activity variables in any group of patients. CONCLUSION: Unlike IL-6, sIL-6R is not produced at the site of inflammation and is not related to clinical or biological disease activity variables. Only in RA are both IL-6 and sIL-6R levels increased, suggesting that sIL-6R may reinforce the systemic effects of IL-6.

Aceclofenac in comparison to ketoprofen in the treatment of rheumatoid arthritis.

The efficacy and tolerability of aceclofenac, a new non-steroidal anti-inflammatory drug (NSAID) was compared to that of ketoprofen in a multicentre, double-blind, prospective, randomized study of 3-months duration in patients with rheumatoid arthritis. One hundred and sixty-nine patients, aged between 22 and 70 years, were included in the study. Patients were randomly assigned to two treatment groups; either aceclofenac 100 mg b.i.d. (87 patients) or ketoprofen 50 mg t.i.d. (82 patients). A placebo tablet was administered to aceclofenac-treated patients to maintain the double-blind conditions of the study. Patients were examined at 15 days and at 1, 2 and 3 months. Efficacy was assessed by the following clinical parameters: Ritchie index, pain on a visual analogue scale, grip strength, morning stiffness, spontaneous morning pain, pain on movement and nocturnal pain, together with functional capacity. Efficacy was demonstrated for both drugs, with progressive improvement in the main clinical evaluation parameters until the end of the treatment period. This was particularly pronounced at 15 days in the aceclofenac group, with a rapid improvement in the Ritchie index (baseline vs 15 days: P < 0.001). Laboratory analyses performed were all within the normal range for both drugs. Eleven patients in the ketoprofen group abandoned the study because of inefficacy, whilst only 4 patients discontinued the treatment for this reason in the aceclofenac group. Eleven patients in the ketoprofen group and 2 patients in the aceclofenac group withdrew from the study because of adverse events. In summary, this study demonstrated that aceclofenac, a new NSAID, is effective in the symptomatic treatment of RA with a minor number of patient withdrawals because of inefficacy and a better safety profile than ketoprofen.

Histologic changes in rheumatoid synovitis induced by naproxen and methotrexate.

OBJECTIVE: To study the changes in rheumatoid synovitis induced by the nonsteroidal antiinflammatory drug (NSAID), naproxen, and methotrexate (MTX). METHODS: Twelve patients were treated with naproxen, and 11 with MTX and a clinical activity index was measured before and after treatment. A synovial biopsy was taken, on entry into the study and after 73 +/- 43 days in the NSAID group and 145 +/- 35 in the MTX group. Synovial cells bearing CD3, CD4, CD8, CD19, LeuM5 (CD11c), HLA-DR, HLA-DP and CD25 antigens were measured by stereology. RESULTS: Patients treated with MTX showed a reduction in the number of CD3+ (p = 0.01), CD4+ (p = 0.007) and HLA-DR+ (p = 0.01) cells with an improvement in the activity index (p = 0.001). The patients treated with naproxen did not show changes in the activity index or in the synovial infiltrate. CONCLUSION: Our findings support the theory that clinical improvement in rheumatoid synovitis is associated with a significant decrease in the number of T cells infiltrating the synovial membrane.

Familial articular chondrocalcinosis in Spain.

One hundred and one first degree relatives of 35 patients with chondrocalcinosis were examined for the presence of familial disease. Eleven subjects from nine families showed radiological chondrocalcinosis, a prevalence of familial disease of 26%. Two different patterns of disease were noted--the older generation was more commonly affected, and the younger generation and second degree relatives were exempt. Clinical and radiological differences were found between the early and late onset groups, but not between late onset and sporadic forms of chondrocalcinosis. These findings support the suggestion that the true prevalence of familial disease. is underestimated. A dominant, autosomal transmission with variable penetrance is consistent with our findings, which suggests that homozygous patients with familial chondrocalcinosis may present a more severe form of the disease.
