Melbye H, Halvorsen DS, Hartz I, Medbø A, Brox J, Eggen AE, Njølstad I. Bronchial airflow limitation, smoking, body mass index, and statin use are strongly associated with the C-reactive protein level in the elderly. The Tromsø Study 2001. Respir Med 2007; 101:2541-9. [PMID: 17825547 DOI: 10.1016/j.rmed.2007.07.018] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2007] [Revised: 07/03/2007] [Accepted: 07/06/2007] [Indexed: 11/23/2022]
Abstract
BACKGROUND Bronchial airflow limitation is a known predictor of raised C-reactive protein (CRP) level. The aim of this study was to explore this association in an elderly population, as well as the influence of other known and possible predictors of the CRP level, like smoking and the use of statins and inhaled corticosteroids. POPULATION AND METHODS The study population consists of 3877 Norwegians aged 60 years or more who took part in the fifth Tromsø study in 2001, a cross-sectional study. The examinations included questionnaires, spirometry and the measurement of CRP. RESULTS A geometric mean CRP value of 3.15 mg/L was found in subjects with severe airflow limitation (FEV(1)%<50 predicted and FEV(1)/FVC<70%), compared to 1.64 mg/L in subjects with normal spirometry, (p<0.001), and 19% of the subjects with severe airflow limitation had a CRP value above 10 mg/L compared to 4.9% in those with mild airflow limitation or normal spirometry. Elevated body mass index (BMI), smoking, hormone replacement therapy, and increasing age, were also strong independent predictors of increased CRP. Statin use was a strong predictor of decreased CRP level, while the use of inhaled corticosteroids was not associated with decreased CRP values. CONCLUSION We found a strong link between bronchial airflow limitation and the circulating CRP level in an elderly population, independent of self-reported diseases, medication, smoking, and elevated BMI. The CRP value increased with increasing age in men, but not in women, which may be partly explained by a greater impact of chronic obstructive pulmonary disease (COPD) morbidity on the CRP level in men than in women. Measuring CRP may show to be a useful part of the diagnostic work-up in COPD patients.

Abstract
We investigated the effects of tai chi on disease activity, flexibility and depression in patients with ankylosing spondylitis (AS). We allocated 40 patients to either a tai chi treatment group or a no-treatment control group. The tai chi group performed 60 min of tai chi twice weekly for eight consecutive weeks and 8 weeks of home-based tai chi, after which the group showed significant improvement in disease activity and flexibility compared to the control group. All outcome measures were significantly lower in the tai chi group than they were during pre-treatment, while they did not change in the control group. These findings suggest that tai chi can improve disease activity and flexibility for patients with AS. Tai chi is an easily accessible therapy for patients and, as such, may be an effective intervention for AS. However, we cannot completely discount the possibility that the placebo effect was responsible for the improvement.

Abstract
OBJECTIVE To longitudinally investigate serum and synovial fluid (SF) levels of RANTES and monocyte chemoattractant protein 1 (MCP-1) as well as in vitro migration of mononuclear cells toward SF in patients with juvenile rheumatoid arthritis (JRA). METHODS Serum and SF levels of RANTES and MCP-1 were determined by enzyme-linked immunosorbent assay. Chemotaxis was performed using the modified Boyden chamber method. RESULTS Serum RANTES levels were significantly increased in all onset types of JRA, with the highest levels present in systemic-onset JRA. Serum MCP-1 levels were significantly elevated in patients with systemic-onset JRA and were associated with current systemic features. Although serum levels of RANTES and MCP-1 decreased significantly after treatment, RANTES and MCP-1 levels during disease remission were still significantly higher in JRA patients than in controls. A relationship was found between serum RANTES levels during remission and the duration of clinical remission, with low levels being associated with prolonged clinical remission and high levels with shorter clinical remission. Serum RANTES levels correlated with C-reactive protein concentrations, hemoglobin values, white blood cell (WBC) counts, and platelet counts, whereas serum MCP-1 levels correlated with WBC counts and serum ferritin levels. Levels of RANTES and MCP-1 in SF were elevated as compared with levels in serum. SF chemotactic activity for mononuclear leukocytes was significantly inhibited by either anti-RANTES or anti-MCP-1 antibody. CONCLUSION RANTES is a key molecule in the pathogenesis of all onset groups of JRA, whereas MCP-1 is particularly important in systemic-onset JRA. Serum levels of these CC chemokines represent more highly sensitive markers of disease activity than conventional markers of inflammation.

Abstract
We investigated the effects of home-based daily exercise on joint mobility, functional capacity, pain, and depression in patients with ankylosing spondylitis (AS). The patients were randomly assigned to a wait-list control group or to an exercise-therapy group. The exercise-therapy group performed a 20-min exercise program once per day for 8 consecutive weeks. After 8 weeks, compared with the control group, the exercise group showed improvements in joint mobility (cervical flexion, extension, shoulder flexion, abduction, hip abduction, and knee flexion), finger-floor distance, and functional capacity. Pain and depression scores were significantly lower after the exercise program in the exercise group than in the control group. These findings indicate that exercise therapy increases joint mobility and functional capacity, and decreases pain and depression in patients with AS. Home-based exercise, which is easily accessible to patients, might be an effective intervention for AS.

Abstract
OBJECTIVE To analyze patterns of stress, mood, disease symptoms, and activity reduction in children with polyarticular arthritis, using a prospective daily diary method. METHODS For a 2-month period, 51 children with polyarticular arthritis (mean age 12.4 years, 65% female) completed daily diaries that included measures of symptoms of pain, stiffness, and fatigue, as well as stress, mood, and activity reduction. Functional status and disease activity were assessed at the initial and followup evaluations with use of the Childhood Health Assessment Questionnaire, physician global assessment, joint count, and laboratory testing. RESULTS Children reported having pain, stiffness, and fatigue on >70% of days, with significant variability in symptom levels. Results revealed significant same-day relationships between stress, mood, and disease symptoms, after controlling for covariates. Specifically, daily fluctuations in both stress and mood were predictive of increased pain, stiffness, and fatigue. Increases in daily stress, mood, and disease symptoms were also significantly related to decreased participation in social activities on a day-to-day basis. Only mood and stiffness were predictors of a cutback in school attendance. CONCLUSION Stress and mood are important predictors of daily disease symptoms in children with polyarticular arthritis. Moreover, daily fluctuations in stress, mood, and disease symptoms are predictive of aspects of daily function, including participation in school and social activities. Thus, health care providers should solicit daily symptom reports when making decisions regarding clinical management. Nonpharmacologic interventions such as cognitive-behavioral therapy and stress management may be useful adjuvant therapy when treating the disease symptoms of children with polyarticular arthritis.

Abstract
OBJECTIVE To analyze patterns of daily pain, stiffness, and fatigue related to juvenile arthritis; to examine the relationships of demographics, disease severity, and psychological adjustment to daily disease symptoms; and to examine daily disease symptoms as predictors of reduced participation in school and social activity. METHODS For a 2-month period, 41 children with polyarticular juvenile arthritis completed daily diaries that included measures of symptoms and function. Children also underwent an initial evaluation and 4 followup evaluations that included a joint count, laboratory testing, and completion of questionnaires assessing physical and psychosocial functioning. RESULTS Children reported having pain an average of 73% of days, with the majority of children (76%) reporting pain on >60% of all days. On average, children described the intensity of their daily pain as being in the mild to moderate range; however, a significant subgroup (31%) reported pain in the severe range. Higher physician global assessment ratings, increased functional disability, and increased anxiety were significantly associated with increased daily pain and other daily symptoms. Multilevel random-effects analyses indicated that increased daily symptoms of pain, stiffness, and fatigue were significant predictors of reduced participation in school and social activities. CONCLUSION Physicians should consider treating pain more aggressively in children with arthritis, in order to preserve function in school and social domains, as well as physical function. Moreover, optimal pain management in children with arthritis should include therapeutic regimens addressing anxiety as well as standard pharmacologic interventions.

Abstract
This chapter reviews the clinical events that occur in patients with juvenile-onset spondyloarthritides (SpA) with the purpose of developing core sets, domains and instruments to evaluate disease activity and disease damage. We discuss several aspects, from concept and classification to clinical features and instruments already in use for measuring adult-onset SpA and childhood arthritides. Similarly, comparisons between juvenile-onset SpA, its adult counterpart, and other forms of juvenile arthritis are made to consider the adaptation of existing instruments or to develop specific ones.

Abstract
Pain in children with juvenile rheumatoid arthritis (JRA) is often not fully recognized and is therefore incompletely treated. The use of pain assessment instruments developed specifically for children may enhance recognition by health care providers. Recent studies suggest that coping variables and disease severity are significant predictors of pain in children with JRA. Pain in children with JRA is a complex phenomenon, best managed using a multidisciplinary approach that includes aggressive traditional medical management and addresses psychosocial variables such as coping strategies and perceptions about disease.

Abstract
In the present study we investigated the influence of methotrexate (MTX) and azathioprine (AZA) on the serum levels of the IgA-alpha 1-antitrypsin (IgA-AT) complex in patients with the systemic form of juvenile chronic arthritis (JCA). Fifty-six JCA patients (22 treated with MTX, 18 treated with AZA, and 16 not treated with any immunosuppressive agent) were enrolled in the study. MTX dosage ranged from 0.3 to 0.5 mg/kg-1 week-1, while AZA was given daily at an average dose of 1 mg/kg. MTX was given for 13 months (SD = 7 months) whereas AZA for 11 months (SD = 6 months). The average value of the complex was higher in JCA patients than in both control groups (0.74 +/- 0.73 U vs 0.37 +/- 0.13 U (control children), P < 0.001 and vs 0.23 +/- 0.12 U (control adults), P < 0.001). Values exceeding the normal range were found in twenty-two JCA patients (39.4%). Serum IgA-AT level was lowest in the MTX group compared to AZA and non-treated patients (0.56 +/- 0.24 U, 0.76 = 0.43 U, 0.95 +/- 0.52 U, respectively, P < 0.05). IgA values exceeding normal levels for age were found in 14% of the patients. A correlation between the levels of the IgA-AT complex and C-reactive protein (r = 0.43, P < 0.01), alpha 1-acid-glycoprotein (r = 0.45, P < 0.01), alpha 1-antichymotrypsin (r = 0.52, P < 0.01), alpha 1-antitrypsin (r = 0.40, P < 0.01) and IgA (r = 0.56, P < 0.01) was established.

Abstract
The assessment of overall health status of a child with juvenile rheumatoid arthritis (JRA) is complex and multi-dimensional. The general physical examination is complemented by a rheumatological evaluation that includes determination of articular indices of inflammation and duration of inactivity stiffness. Laboratory assessment plays a critical role in monitoring side effects of pharmacologic management, but is limited in its ability to portray accurately the degree of active inflammation. Newly measureable indicators of inflammatory activity, such as serum cytokine and soluble cytokine receptors will likely become part of routine laboratory assessment in the future. Radiographs remain a useful tool for assessing disease progression, but may be replaced in the future by magnetic resonance imaging. In recent years, rheumatologists have realized that measurement of overall physical and psycho-social functional ability, quality of life, and pain are major descriptors to consider during routine follow-up. They are also critical in the assessment of long-term clinical effectiveness. The importance of nutritional assessment has also been realized. This section seeks to describe some of the methodologic approaches currently used to assess the variables mentioned above, and includes a brief discussion of the evolving instrumentation which attempts to measure variables of a more cognitive or subjective aspect.

Abstract
The acute phase reaction is in most circumstances a good indicator of (local) inflammatory activity and tissue damage. CRP is a direct and quantitative measure for the acute phase reaction and due to its fast kinetics provides adequate information of the actual situation. The ESR on the contrary is in fact an indirect measure of the acute phase reaction. It does react much slower to changes of inflammatory activity and is influenced by a number of other factors. From studies on the 'behaviour' of CRP it has become clear that diseases may differ with regard to the extent in which they induce an acute phase response. Incidental measurement of the CRP level may add to the diagnostic procedure in selected cases, e.g. in the differentiation between a bacterial and a viral infection or between a bacterial infection and an exacerbation of diseases like SLE. In case of an extremely elevated CRP level (> 100 mg/litre) the possibility of a bacterial infection should always be considered. In clinical practice CRP is particularly useful when serial measurements are performed. The course of the CRP level may be useful for the monitoring of the effect of treatment and for the early detection of postoperative complications or intercurrent infections. The relationship between CRP and the local production and effects of cytokines on the one hand, and the possible functional role of CRP in the inflammatory process on the other hand have surely added a dimension to the clinical use of CRP as a parameter of inflammatory activity.

Abstract
We measured interleukin-6 (IL-6) levels in 70 serum samples obtained from 25 patients with systemic-onset juvenile rheumatoid arthritis (JRA), using the hybridoma cell line B9. Patients with systemic-onset JRA had significantly elevated serum IL-6 levels during active disease (mean +/- SD 92.1 +/- 75.1 hybridoma growth factor units/ml; P less than 0.00001 versus healthy age-matched controls), but not during remission. Serum IL-6 levels correlated with the extent and severity of joint involvement (P less than 0.001) and with platelet counts (P less than 0.05). Our data suggest that IL-6 plays a significant role in the pathogenesis of systemic-onset JRA.

Abstract
To find out whether disease activity and B27 status were associated with serum concentrations of IgA, C reactive protein (CRP), and haptoglobin in ankylosing spondylitis (AS) multivariate analysis of variance was used to study 101 patients with AS whose disease was clinically classified as active or inactive, and who were HLA-B27 typed. It was found that B27 and disease activity do interact significantly to affect the serum concentrations of IgA, CRP, and haptoglobin. When the 77 B27+ patients were examined, however, it was found that disease activity was significantly associated with serum concentrations IgA. In contrast, in the 24 B27- patients concentrations of serum IgA were significantly associated with disease activity, but not. These results emphasise the known difference between B27+ and B27- AS and suggest different pathogenic mechanisms in the two forms of AS.
