A multicentre study of 513 Danish patients with systemic lupus erythematosus. I. Disease manifestations and analyses of clinical subsets.

A Danish multicentre study was undertaken of the manifestations, infections, thrombotic events, survival and predictive factors of survival in 513 Danish patients with systemic lupus erythematosus (SLE) according to the 1982 classification criteria of the American College of Rheumatology. The mean duration of follow-up was 8.2 years from diagnosis and 12.8 years from first symptom. This paper describes the most common clinical and laboratory manifestations and their relationship to sex and age at the time of onset and diagnosis. Cluster analysis revealed three clinically defined clusters at the time of disease onset. Cluster 1 (57% of patients) consisted of relatively elderly patients without nephropathy or malar rash, but with a high prevalence of discoid lesions. Cluster 2 (18%) consisted of patients with nephropathy, a third of whom also developed serositis and lymphopenia. The patients of the third cluster (25%) all had malar rash and half were photosensitive. Follow-up showed that the patients of cluster 2 developed azotaemia, large proteinuria, arterial hypertension and myositis significantly more often than did the rest of the patients, but the mortality was not increased. The risk of developing renal end-stage disease was highest in men with early-onset disease.

A multicentre study of 513 Danish patients with systemic lupus erythematosus. II. Disease mortality and clinical factors of prognostic value.

In this Danish multicentre study, predictive clinical factors of mortality and survival were calculated for 513 patients with systemic lupus erythematosus (SLE), 122 of whom died within a mean observation period of 8.2 years equalling a mortality rate of 2.9% per year. Survival rates were 97%, 91%, 76% and 64% after 1, 5, 10 and 15 years, respectively. The direct causes of death included SLE (n = 35), infections (n = 25), malignancy (n = 9), cardiovascular disease (n = 32) and other causes (n = 21). Uni- and multivariate analyses of survival and mortality were performed for all deaths and for SLE-related deaths. Azotaemia (one-fifth of the patients) was a strong predictor of increased overall and SLE-related mortality, but nephropathy per se (one-half of the patients) and large proteinuria (one-sixth of the patients) were unrelated to survival. Haemolytic anaemia had a significant negative influence on survival related to mortality caused by infections. Diffuse central nervous system disease and myocarditis were related to increased SLE-related mortality, whereas photosensitivity predicted a decreased mortality. Non-fatal infections and thrombotic events predicted a decreased overall survival. Since 1980 the mortality caused by SLE manifestations has decreased significantly.

Effect of i.v. ketamine in combination with epidural bupivacaine or epidural morphine on postoperative pain and wound tenderness after renal surgery.

We studied 60 patients undergoing operation on the kidney with combined general and epidural anaesthesia, in a double-blind, randomized, controlled study. Patients were allocated to receive a preoperative bolus dose of ketamine 10 mg i.v., followed by an i.v. infusion of ketamine 10 mg h-1 for 48 h after operation, or placebo. During the first 24 h after surgery, all patients received 4 ml h-1 of epidural bupivacaine 2.5 mg ml-1. From 24 to 48 h after operation, patients received epidural morphine 0.2 mg h-1 preceded by a bolus dose of 2 mg. In addition, patient-controlled analgesia (PCA) with i.v. morphine (2.5 mg, lockout time 15 min) was offered from 0 to 48 h after operation. Patients who received ketamine felt significantly more sedated at 0-24 h, but not at 24-48 h after operation, compared with patients who received placebo (P = 0.002 and P = 0.127, respectively). There were no significant differences in pain (VAS) at rest, during mobilization or cough, PCA morphine consumption, sensory block to pinprick, pressure pain detection threshold assessed with an algometer, touch and pain detection thresholds assessed with von Frey hairs, peak flow or side effects other than sedation. The power of detecting a reduction in VAS scores of 20 mm in our study was 80% at the 5% significance level. We conclude that we were unable to demonstrate an (additive) analgesic or opioid sparing effect of ketamine 10 mg h-1 i.v. combined with epidural bupivacaine at 0-24 h, or epidural morphine at 24-48 h after renal surgery.

CC chemokine receptor 5 polymorphism in rheumatoid arthritis.

OBJECTIVE: Some chemokine receptors have been shown to be co-receptors for human immunodeficiency virus (HIV-1). A 32 base pair deletion allele in the CC chemokine receptor 5 gene (CCR5 delta32 allele) affects both transmission of HIV-1 and acquired immunodeficiency syndrome (AIDS)-free survival. Chemokines are suggested to be critical for establishment of inflammatory processes in autoimmune diseases such as rheumatoid arthritis (RA). We hypothesized that the defective allele may modulate the inflammatory process in RA. METHODS: Using polymerase chain reaction methods, we investigated the significance of the CCR5 delta32 allele in 163 Danish patients with RA and monitored clinical and paraclinical variables. RESULTS: The gene frequency of the CCR5 delta32 allele (0.10) did not deviate significantly from healthy controls and from that reported in healthy Caucasian populations, nor did the distribution deviate from the Hardy-Weinberg predictions (131 wild type, 30 heterozygous, 2 homozygous for the deletion allele; p = 0.85). However, a significantly increased proportion of those carrying the deletion allele were negative for IgM rheumatoid factor (RF) compared to those homozygous for the normal allele (29 vs 9%; p = 0.007). The proportion of CCR5 delta32 allele carriers with swollen joints was decreased compared to those homozygous for the normal allele (35 vs 58%, respectively; p = 0.03), as was the duration of morning stiffness (median 0 vs 60 min, respectively; p = 0.0002). CONCLUSION: The CCR5 delta32 allele seems to have some influence on RA variables including RF, which suggests that inhibition of chemokine receptors might be a potential target for disease modifying therapy in RA.

Limited effect of sulphasalazine treatment in reactive arthritis. A randomised double blind placebo controlled trial.

OBJECTIVE: To assess the efficacy and safety of sulphasalazine in reactive arthritis. METHODS: Double blind placebo controlled trial of six months duration comparing sulphasalazine 2-3 g per day (n = 37) with matching placebo (n = 42) in adults with active reactive arthritis (age 19-57 years, median 34). Treatment response was evaluated once a month by changes in erythrocyte sedimentation rate (ESR), pain, peripheral arthritis, tender iliosacral joints, entesopathy, extra-articular manifestations, and working ability. RESULTS: 15 patients in the sulphasalazine group and eight in the placebo group withdrew from the study prematurely. Adverse events, primarily gastrointestinal, were the main reason for withdrawal in the actively treated group. Intention-to-treat analyses showed significant improvements over time in both groups in ESR, pain, and number of swollen joints (P < 0.01). Number of days on sick leave decreased significantly in the sulphasalazine group only (P < 0.01). No significant differences between the two groups were present after six months. Among the patients completing the trial according to protocol, persistent complete remission had occurred within two months in five (23%) of the actively treated, but in no placebo treated patients (P = 0.013). CONCLUSIONS: Sulphasalazine seemed to improve only the very short term outcome of reactive arthritis. The possible beneficial effect of the drug should also be weighed against the risk of adverse events. Although these were mainly mild, almost 25% of the patients in the actively treated group gave up treatment for this reason.

Prospectively measured red cell folate levels in methotrexate treated patients with rheumatoid arthritis: relation to withdrawal and side effects.

OBJECTIVE: To investigate whether red cell folate (RCF) levels relate to side effects, withdrawals, or disease activity during treatment with the folic acid antagonist methotrexate (MTX) for rheumatoid arthritis (RA). METHODS: Side effects were recorded monthly, RCF levels were measured by lactoglobulin binding radioassays, and 8 variables for disease activity were measured in a placebo controlled double blind trial of 28 weeks' duration comparing efficacy of MTX (n = 23) and D-penicillamine (n = 23). RESULTS: From Week 20 RCF levels decreased only in the MTX group (p < 0.02), and 5 MTX treated patients withdrew due to side effects. Withdrawals had lower RCF values at Weeks 0 and 9 compared to the remaining patients (p < 0.05). Folate deficiency evolved in 5 patients; 2 of these developed cytopenia. Aberrations in the scheduled dosage increase were related to lower pretreatment values of RCF (p = 0.007). Side effect scores were inversely correlated to RCF values at Weeks 0, 9, and 28 (p < 0.05). RCF levels measured concomitantly with liver enzyme elevation were lower than the remaining values (p < 0.001). When side effects were reported, 96% of concomitantly measured RCF values were below 800 nmol/l. RCF values at entry did not correlate to improvement in any variable for disease activity, or a graded overall improvement. CONCLUSION: RCF levels decrease during MTX treatment and relate to side effects, withdrawals, liver enzyme elevations and aberrant MTX dosage increase, but not to the therapeutic effect. RCF above 800 nmol/l protects against side effects.

[Testing a medically-staffed ambulance in Aarhus. A pilot study].

As an attempt to assess the value of a medically-staffed mobile emergency care unit in Aarhus City, we carried out a seven-day experiment (17 hours per day) with an anaesthesiologist and a nurse on duty in a fully equipped vehicle. Aarhus City is an area of approximately 300 km2, with a population of 330,000. The unit responded to emergency calls in 106 patients (38% of all emergency calls during this week). In 31% of all cases the response-time was less than five minutes. Medical disease was diagnosed in 73 patients. Twenty-three patients were suffering from trauma and in three cases the reason for the emergency call was attempted suicide. Fifty-seven percent were treated immediately by the emergency unit, and in 4% of these the treatment was lifesaving. Twenty percent of the patients had their treatment completed outside the hospital. Eighty percent were brought to hospital, 47% with medical assistance. We conclude that there seems to be a basis for a medically-staffed mobile emergency care unit in Aarhus City.

Serum from NSAID-treated patients attenuates the capacity of rat leukocytes to synthesize leukotriene B4.

The synthesis of leukotriene B4 by A23187-stimulated rat peritoneal leukocytes was studied in the presence of 0.1% normal human serum, serum from patients treated with NSAIDs for either an inflammatory (rheumatoid arthritis, RA) or a non-inflammatory condition (lumbar disc protrusion, LDP), and serum from RA patients drawn one week after withdrawal from NSAID treatment. The capacity for LTB4 synthesis was significantly lower in the presence of serum from NSAID treated patients: thirty per cent less than observed in presence of normal serum in the RA group, and fifty per cent in the LDP group. When NSAIDs were withdrawn from RA patients, the LTB4 production in presence of serum increased, but was not completely normalized after one week. These results indicate that NSAID treatment may down-regulate the capacity for leukotriene synthesis by an indirect effect.

Randomized, placebo controlled trial of withdrawal of slow-acting antirheumatic drugs and of observer bias in rheumatoid arthritis.

Patients with rheumatoid arthritis, in stable treatment with methotrexate, penicillamine, or sulfasalazine, were randomized in a double-blind fashion either to continuation of their usual treatment or to placebo. 112 patients were included; 52 patients who refused participation had no more severe disease than the others. The patients felt worse on placebo than on active drug (p = 0.002). The mean differences in number of tender, painful and swollen joints after one month were 2.4 (p = 0.08), 3.0 (p = 0.12) and 2.2 (p = 0.03), respectively. Treatment failure occurred for 42 patients of whom 33 received placebo (p = 0.000,001). There was no difference in the severity of side effects (p = 0.91). The patients guessed their treatment correctly more often than expected (p = 0.02) because of the perceived effect. None of the two observers guessed better than chance, and there were no differences between the observers' evaluations of the joints. The effect of slow-acting antirheumatic drugs was unequivocal and no observer bias occurred.

[Fish oils and rheumatoid arthritis. A randomized and double-blind study].

The effect of dietary supplementation with n-3 polyunsaturated fatty acids (n-3 PUFA) on disease variables in patients with active rheumatoid arthritis was evaluated in a multicentre, randomized and double blind study. Fifty-one patients with active rheumatoid arthritis were included from three Danish hospital Departments of Rheumatology. The patients were allocated to 12 weeks of treatment with either six n-3 PUFA capsules (3.6 g) or six capsules with a fat composition averaging the Danish diet. Small but significant improvements in morning stiffness, joint tenderness and C-reactive protein were observed. There were no serious side-effects. Dietary supplementation with n-3 PUFA in patients with active rheumatoid arthritis has a modest effect on three out of eight disease variables, without effect on other traditional parameters for monitoring disease activity.

Serum transferrin receptor levels in anaemic patients with rheumatoid arthritis.

The value of s-Transferrin Receptor (s-TfR) measurements in recognizing simultaneous iron deficiency in anaemia of chronic disease was examined in 35 anaemic patients with active rheumatoid arthritis. Based on a quantification of stainable bone marrow (marrow iron grade 0-4) and serum ferritin concentrations (levels < 60 micrograms l-1) compatible with iron deficiency) the anaemia was found to be aggravated by iron deficiency in 19/35 or 54% of the patients. There was no significant difference between the mean s-TfR concentrations in patients with adequate iron in comparison to patients with iron depletion [2.9 (1.6) mg l-1 v. 2.7 (1.4) mg l-1; t = 0.273; p = 0.786; Student's t-test]. Mean s-TfR levels in both patients with adequate iron and depleted iron stores were within the normal range, but tended to be higher than in normal individuals [mean (SD): 1.54 (0.43) mg l-1]. In patients with no stainable marrow iron (MIG 0; N = 15) a significant inverse correlation was found between s-TfR concentrations and s-ferritin levels (r = 0.57; p < 0.05). 5/15 patients with MIG = 0 exhibited significantly raised concentrations of s-TfR values > 3.05 mg l-1 (the highest normal value of the normal range). Increases of s-TfR levels were consistently moderate, and never exceeded a level of 7 mg l-1, which is markedly lower than concentrations measured in patients with iron deficiency anaemia.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical examination of pelvic insufficiency during pregnancy. An evaluation of the interobserver variation, the relation between clinical signs and pain and the relation between clinical signs and physical disability.

The purpose of this study was to answer the following questions: Do clinical signs in pregnant women with pelvic pain differ from signs in those without pelvic pain? Is there variation between the test signs found by four observers? Are the clinical signs correlated to pain and physical disability? Twenty pregnant women with pelvic pain and 20 pregnant women without pelvic pain were participating. Each woman reported her own pain sensation and physical disability and each woman was examined by 4 physiotherapists independently. Sixty-one clinical tests were applied. Only 8 tests showed predominantly positive signs in the pain group. These tests showed agreement between different observers judged by a kappa coefficient > 0.40. The number of positive clinical signs was well correlated to the reported pain and physical disability. The value of an extensive examination of posture, muscles and joints on pregnant women with pelvic pain is dubious.

[Biochemical markers in RA].

Inflammatory activity is usually (but not always) accompanied by increases in the plasma concentrations of acute-phase reactants such as C-reactive protein (CRP), fibrinogen etc. The most widely used and most sensitive variable is the CRP value. Increase in the concentrations of acute-phase reactants is accompanied by increase in the ESR (erythrocyte sedimentation rate), though increase in ESR may also be secondary to hypergammaglobulinaemia and anaemia without co-existing inflammation. The measurement of various connective tissue markers in the blood, synovial fluid and urine has opened up the way to new possibilities for evaluating synovial inflammation, pannus formation, and cartilage and bone destruction.

Hydroxychloroquine and sulphasalazine alone and in combination in rheumatoid arthritis: a randomised double blind trial.

OBJECTIVES: To compare the effects of hydroxychloroquine and sulphasalazine alone and in combination in rheumatoid arthritis. METHODS: A six month randomised, multicentre, double blind trial with three parallel groups was performed. Ninety one outpatients with active rheumatoid arthritis were included. Monthly assessments of erythrocyte sedimentation rate, morning stiffness, number of swollen joints, a pain score, and global assessments were carried out. Radiographs of hands and wrists were taken before and after the trial. RESULTS: Sixty two patients completed the study. The 29 withdrawals caused no evident bias, and there was no difference in side effects among the three groups. All variables improved significantly with time. Patients treated with a combination of hydroxychloroquine and sulphasalazine responded better and faster than those treated with hydroxychloroquine alone, but there was no statistically significant difference between the combination treatment and single drug treatment with sulphasalazine or between treatment with hydroxychloroquine and sulphasalazine given alone. CONCLUSION: The present results do not support a recommendation to use a combination of hydroxychloroquine and sulphasalazine in the treatment of rheumatoid arthritis.

Longterm physical training in rheumatoid arthritis. A randomized trial with different training programs and blinded observers.

The objective was to study the long-term effect (2 years) of different training programs in patients with rheumatoid arthritis. The method was a randomized trial with 75 patients participating. The measured variables included morning stiffness, a pain score, number of swollen joints, a health assessment score, a functional score, ESR, Hb, the cost of medicine, and progression using X-rays of hands and feet. The results showed no effect of training on the disease activity or on the progression of the disease. The conclusion is that although most patients are in favour of training, the present study does not support that training lessons per se affect the disease activity or the progression of the disease.
