The relationship between psychosocial variables and pain reporting in osteoarthritis of the knee.

Psychosocial factors may explain some of the variation in pain reporting among individuals with knee OA. This has important potential implications for management; indeed, several studies (reviewed in ref. 56) have demonstrated that interventions may reduce knee pain without apparent halting or reversing of structural damage. Such interventions have included the simple provision of support by monthly telephone calls (57), self-management programs (58), and cognitive-behavioral approaches designed to teach patients ways of coping with their pain (59). These programs are even more effective if the spouse is involved (60). It should be noted that there may be a large placebo effect in these interventions, and the degree to which patients are responding simply to an interest being taken in them and their problems is unclear; at least one study has shown that formal cognitive-behavioral therapy is no better than didactic education at improving pain and function in knee OA (though both are beneficial) (61). Many studies examining the role of psychosocial factors have suffered from poor design; many, for example, fail to control for radiographic severity. Future studies should define how pain is identified (dichotomous, ever/never/current, severity), differentiate community and hospital subjects, and separate patients by type and location of OA. Studies should also control for other factors potentially associated with pain: obesity, comorbidity, muscle weakness, and aerobic fitness. Prospective studies would allow clarification of the cause and effect relationship between anxiety, depression, and pain, both in the community and in patients who have elected to seek medical help. In this way, we may increase our understanding of the complex interaction between mood, social factors, and pain reporting in knee OA and, thus, improve the effectiveness, already equivalent to many pharmacologic interventions, of treatments designed to address psychosocial factors.

The prevalence and impact of self-reported hip fracture in elderly community-dwelling women: the Women's Health and Aging Study.

To estimate the prevalence and impact of self-reported hip fracture in elderly women an age-stratified random sample of 3841 community-dwelling women aged 65 years and above were interviewed to determine the occurrence of 13 chronic conditions and difficulty performing 15 tasks. Associations were examined using multiple logistic regression analysis. The weighted prevalence of hip fracture was 4.7 per 100. Prevalence increased with increasing age from 2.9 per 100 in women aged 65-74 years to 12.6 per 100 in women aged 85 years and above, and was higher in white women than black women. Women with hip fracture were significantly more likely to report concomitant Parkinson's disease (age-adjusted odds ratio [aOR] = 2.8) and stroke (aOR = 1.8). After adjustment for potential confounding variables, women with hip fracture were significantly more likely to report difficulty performing 11 activities that map into domains of mobility/exercise tolerance, self-care tasks and higher functioning domains. Hip fracture is common among elderly community-dwelling women and is associated with difficulty in performing activities of daily living.

An association between an aggrecan polymorphic allele and bilateral hand osteoarthritis in elderly white men: data from the Baltimore Longitudinal Study of Aging (BLSA).

OBJECTIVE: The aggrecan proteoglycan is a major component of articular cartilage and supports the biomechanical function of this tissue. A variable number tandem repeat (VNTR) polymorphism has been discovered recently in a region of the human aggrecan gene that codes for the chondroitin sulfate attachment sites. We examined whether alleles of this polymorphism displayed a non-random association with bilateral hand or knee osteoarthritis (OA) in men from the Baltimore Longitudinal Study of Aging (BLSA). DESIGN: DNA was obtained from 93 Caucasian men, aged 60 and above, who had bilateral hand and standing knee radiographs read for changes of OA. The DNA was analyzed by polymerase chain reaction (PCR) and/or Southern blotting for the presence of the VNTR alleles. RESULTS: Bilateral hand OA and knee OA were present in 46 and 30% of the men respectively. The following distribution of alleles was observed: allele 33 (0.5%), 29 (2.2%), 28 (31.7%), 27 (43.0%), 26 (16.7%), 25 (3.2%), 22 (2.2%) and 19 (0.5%). This distribution was similar to that detected in a random population of individuals from a separate study. In multiple logistic regression analysis, adjusting for age and body mass index, the presence of allele 27 was associated with bilateral hand OA with an odds ratio (OR) = 3.23 (95% confidence intervals (CI): 1.24-8.41). No other alleles showed an association with bilateral hand OA and the association between allele 27 and bilateral knee OA was not statistically significant (OR = 1.14; 95% CI: 0.45-2.88). CONCLUSIONS: These data demonstrate the first association between a human aggrecan gene polymorphic allele and hand OA. This finding supports the concept that genetic factors may play a role in the development and/or progression of some forms of age-onset OA.

Where does it hurt? Pain localization in osteoarthritis of the knee.

OBJECTIVE: To identify the most common sites of pain in symptomatic knee osteoarthritis (OA) and to investigate clinical, radiographic and psychosocial associations of pain occurring in different locations. DESIGN: Sixty-eight outpatients with knee OA were interviewed in detail about their knee pain. Location of pain was recorded on a standard drawing of the knee. Validated instruments were used to measure pain severity, function, depression, anxiety, quality of life, fatigue, helplessness, self efficacy. Pain threshold was measured by dolorimetry and a knee examination performed. Radiographs (anterioposterior and lateral) were viewed if available. RESULTS: Most (85.3%) patients reported either 'generalized' (N = 35, 51.5%) or 'medial' (N = 23, 33.8%) knee pain. There were no differences between groups in pain severity, demographic or psychosocial variables, pain threshold or radiographic location or severity. However, function was significantly worse in the 'generalized' group (WOMAC function score 48.9 +/- 20.8 vs 34.2 +/- 22.3; P = 0.01): this remained significant after adjustment for potential confounding factors. The difference in function was most marked for activities involving knee bending. Early morning stiffness was also greater in the generalized group. CONCLUSIONS: Knee pain is not the same in all individuals with knee OA, confirming the heterogeneity of the condition. Location of pain is usually either generalized or medial. Patients with these patterns do not differ in demographic, radiographic or psychosocial variables but important differences in functional ability can be detected, suggesting differences in the underlying causes of pain and disability between the two groups.

Prevalence of symptoms of dry mouth and their relationship to saliva production in community dwelling elderly: the SEE project. Salisbury Eye Evaluation.

OBJECTIVE: To estimate the prevalence of dry mouth symptoms and their correlation with saliva production in a population based sample of elderly people in the United States. METHODS: Two dry mouth questions were administered to and a modified Saxon test was performed in participants in a population based prevalence survey conducted among 2520 noninstitutionalized community dwelling residents of Salisbury, Maryland, aged 65-84 years. RESULTS: Seventeen percent reported having either dryness of mouth or waking at night feeling dryness in the mouth and needing to drink fluids often or all the time; 10.7% noted the former and 11.5% the latter. The prevalence of dry mouth symptoms increased with increasing age, was greater in women than men, and was greater in whites than blacks. The mean (SD) amount of saliva production was 2.38 (1.00) g/min; mean saliva production decreased with increasing age and was lower in women than men; no difference was noted by race. Persons with dry mouth symptom either often or all the time had significantly lower salivary production, even after adjustment for age and sex. CONCLUSION: Symptoms of dry mouth are common in the community dwelling elderly population, especially in white women, and correlate with decreased salivary production.

Juvenile dermatomyositis at diagnosis: clinical characteristics of 79 children.

OBJECTIVE: To evaluate demographic and clinical characteristics, duration of time between disease onset (date of first rash and/or weakness), and diagnosis/therapy, as well as socioeconomic status, of children with newly diagnosed juvenile dermatomyositis (JDM). METHODS: Structured telephone interview of families of a cohort of 79 children with JDM: interval between onset of symptoms to diagnosis, median of 3 months (range 0.5-20.0). RESULTS: At diagnosis, all the children had rash (100%) and proximal muscle weakness (100%); 58 (73%) had muscle pain; 51 (65%) fever; 35 (44%) dysphagia; 34 (43%) hoarseness; 29 (37%) abdominal pain; 28 (35%) arthritis; 18 (23%) calcinosis, and 10 (13%) melena. Muscle derived enzymes were normal in 10% of the children. Of the 43 children who had an electromyogram (EMG), 8 (19%) had normal results. Fifty-one children had a muscle biopsy; the results were normal/nondiagnostic in 10 (20%). Median time from disease onset to diagnosis was different between racial groups: Caucasians (n=59) 2.0 months: for minorities (n=20), 6.5 months, (p=0.0008). The median time from disease onset to therapy was: Caucasians. 3.0 months; minorities, 7.2 months (p=0.002). Report of calcinosis was associated with increased time to diagnosis and therapy (p=0.04). In the 33 children whose first symptom occurred in June-September, rash preceded or accompanied onset of muscle weakness in 83% (n=27). Ninety-one percent of the children were given steroid therapy and 9% received methotrexate as well. CONCLUSION: The results of an undirected site for muscle biopsy or EMG may not be diagnostic. Minority children had a longer interval between first JDM symptom and diagnosis/therapy than Caucasian children. Delay in diagnosis/therapy was associated with calcinosis.

Management of osteoarthritis in older adults.

Management of osteoarthritis (OA) is directed primarily towards relief of pain and functional limitation. This article discusses a range of nonpharmacologic modalities, including education, social support, weight reduction, and exercise. Drug treatment should begin with adequate doses of acetaminophen. Guidelines for appropriate use of NSAIDs also are suggested in this article. Intraarticular steroids help a proportion of patients, particularly those with OA of the knee or thumb base; the role of intraarticular therapies remains uncertain. Surgery (total joint replacement) remains an excellent treatment for patients in whom medical treatment has failed to provide adequate symptom relief. Future developments are likely to include earlier intervention using drugs with the potential to modify the course of the disease.

Gout and risk for subsequent coronary heart disease. The Meharry-Hopkins Study.

BACKGROUND: Patients with gout are encountered frequently in clinical practice. Previous studies have suggested that hyperuricemia and gout may represent risk factors for coronary heart disease (CHD), the most common cause of death in American men. METHODS: Prospectively collected data from 2 longitudinal cohort studies of former medical students--371 black men in the Meharry Cohort Study and 1181 white men in the Johns Hopkins Precursors Study--were analyzed. The development of gout and of CHD was determined by physician self-report, and validated by using published criteria. The risk for CHD associated with gout was evaluated using Cox proportional hazards analysis. RESULTS: During a median follow-up of 30 years, there were 38 gout cases and 44 CHD events among the Meharry men, and 68 gout cases and 138 CHD events among the Hopkins men. Prior gout was not associated with an increased risk for incident CHD (relative risk = 1.20; 95% confidence interval, 0.37-3.92) among the Meharry men or among the Hopkins men (relative risk = 0.66; 95% confidence interval, 0.24-1.79). Multivariate analysis adjusted for known CHD risk factors did not alter these findings. CONCLUSION: These results, in black and white male physicians, do not suggest a role in men for targeting gout identification in the primary prevention of CHD.

New-onset juvenile dermatomyositis: comparisons with a healthy cohort and children with juvenile rheumatoid arthritis.

OBJECTIVE: To determine, in a case-control study, if patients with new-onset juvenile dermatomyositis (juvenile DM) have increased symptoms prior to onset, exposure to certain environmental conditions, frequency of familial autoimmune diseases, or antibody titers, compared with 2 control groups. METHODS: A structured interview with the families of 80 children with juvenile DM, 40 children with juvenile rheumatoid arthritis (JRA), or 23 healthy children, from the same geographic area as the children with juvenile DM, was conducted. All children's sera were tested for antibody to Toxoplasma gondii, herpes simplex virus (HSV), or coxsackievirus B (CVB). RESULTS: A high proportion of children with juvenile DM had constitutional symptoms 3 months before the disease-onset date (P = 0.013 versus control children). Children with JRA had more relatives with rheumatoid arthritis (P = 0.0001) and pernicious anemia (P = 0.003) than did children with juvenile DM or healthy children. Among children < or =7 years of age, elevated enteroviral titers were more frequent in those with juvenile DM (81%) and in healthy controls (90%) than in those with JRA (64%), suggesting a common environmental exposure. Titers to T gondii, HSV, or CVB 1-6 were normal. CONCLUSION: Frequencies of familial autoimmune disease, exposure to environmental factors, or elevated antibody titers to T gondii, HSV, or CVB are not increased in juvenile DM. Children with juvenile DM do have symptoms of illness 3 months before the disease-onset date, and young patients have elevated enteroviral titers, as do young geographic controls.

A systematic review of randomized controlled trials of pharmacological therapy in osteoarthritis of the knee, with an emphasis on trial methodology.

We systematically reviewed randomized controlled trials (RCTs) of pharmacological therapy in knee osteoarthritis (OA), published between 1966 and August 1994. RCTs were identified by MEDLINE, supplemented by a manual search of reference lists. Qualitative assessment of RCTs was performed using Gotzsche's method; design and analysis features were rated on a scale of 0 (worst) to 8 (best). Heller et al's method was used to compare efficacy of nonsteroidal antiinflammatory drugs (NSAIDs) in comparative trials. A total of 80 RCTs were analyzed (45 involved NSAIDs, 3 analgesics, 5 intraarticular [IA] steroids, 9 biological agents, including IA hyaluronic acid, and 18 mixed modalities, including topical capsaicin). The median design and analysis scores for all 80 RCTs were 2 and 5, respectively. NSAIDs were superior to placebo in all short-term trials, but in the 32 comparative NSAID trials, only five (16%) found significant differences in efficacy. Heller et al's method identified differences in 14 NSAID comparisons; etodolac (600 mg/day) was superior in five of its nine comparisons. Indomethacin and aspirin were the most toxic NSAIDs. IA steroids were superior to placebo in short-term efficacy (< 1 month). Biological agents were superior to placebo and generally well tolerated over a mean follow-up of 48 weeks. Acetaminophen was superior to placebo and was comparably efficacious to low-dose naproxen and ibuprofen (< 2,400 mg/day). The data support the use of acetaminophen, topical capsaicin, IA steroids, IA hyaluronic acid, and NSAIDs in the treatment of patients with knee OA.

A systematic review of randomized controlled trials of pharmacological therapy in osteoarthritis of the hip.

OBJECTIVE: To systematically review all randomized controlled trials (RCT) of pharmacological therapy in osteoarthritis (OA) of the hip. To determine which nonsteroidal antiinflammatory drug (NSAID) is the most effective, and which NSAID is the most toxic. METHODS: A MEDLINE search was used to identify RCT of pharmacological therapy in patients with OA of the hip published between 1966 and August 1994. Qualitative assessments were performed using a quality scoring system designed for NSAID trials in rheumatoid arthritis. Both the design and analysis aspects of the trials were evaluated, each aspect rated on a scale of 0 to 8. A quantitative method, which calculates the ratio of improvement produced by one NSAID to that produced by another, was used to rate the relative efficacy of different NSAID with respect to pain relief. Toxicity comparisons were made according to the authors' findings. RESULTS: 43 RCT were identified, and of these, 39 evaluated NSAID while 4 evaluated only analgesics. The median design and analysis scores were 2 and 4, respectively, 6 NSAID were included in at least 5 trials; of these, indomethacin was rated more effective in 5 of its 7 comparisons, but more toxic in 7 of 12 comparisons. Only 5 of the 29 (17%) NSAID comparisons found statistically significant differences in efficacy. CONCLUSION: NSAID trials in patients with OA of the hip appear to be weakened by the lack of standardization of case definition of OA, and also by the lack of standardization of outcome assessments. No recommendations for the choice of specific NSAID therapy in hip OA can be offered based on this analysis.

Metabolic correlates of obesity and radiographic features of knee osteoarthritis: data from the Baltimore Longitudinal Study of Aging.

OBJECTIVE: To examine the relationship between metabolic correlates of obesity and radiographic knee osteoarthritis (OA). METHODS: We included 464 Caucasian men and 275 Caucasian women aged 40 years and above who were participants in the Baltimore Longitudinal Study of Aging. Subjects had bilateral anteroposterior standing knee radiographs read for features of OA using Kellgren-Lawrence scales. Resting blood pressure, fasting lipids, 2 h oral glucose tolerance test, and anthropometric measurements were obtained at the same visit as the knee radiograph. Metabolic correlates of obesity were compared between subjects with Kellgren-Lawrence grade > or = 2 (definite knee OA) and grade 0 (normal radiograph) by sex. RESULTS: Both men and women with knee OA had higher unadjusted systolic blood pressure than those with normal knee radiographs; unadjusted measures of glucose metabolism and lipids did not vary by presence of knee OA in men or women. After adjustment for age and obesity, systolic blood pressure did not vary by presence of knee OA in men. While women with knee OA did have higher adjusted mean systolic blood pressure than women with normal radiographs (127 +/- 2.4 vs 120 +/- 2.2 mm Hg; p = 0.04), both values were within normal range. Unexpectedly, men with knee OA had lower adjusted mean 2 h glucose levels compared to men without OA (7.5 +/- 0.2 vs 8.4 +/- 0.2 mmol/l; p = 0.01). Other adjusted variables did not differ by presence of knee OA. CONCLUSION: These data do not support the hypothesis that metabolic correlates of obesity are independently associated with radiographic knee OA after adjustment for age and obesity.

Design and conduct of clinical trials in osteoarthritis: preliminary recommendations from a task force of the Osteoarthritis Research Society.

In 1994, a combined committee of the World Health Organization and the International League of Associations for Rheumatology published recommendations for clinical trials for 2 classes of agents for treatment of osteoarthritis (OA) that relieved symptoms but differed in their onset and duration of response, and a third class of agents that may alter the disease process. Recently, the European Group for the Respect of Ethics and Excellence in Science made recommendations for methods to be used in the registration of drugs for OA. Following the 2nd international meeting of the Osteoarthritis Research Society in December 1994, a task force was convened to develop recommendations for the design and conduct of clinical trials in patients with OA. The Task Force had several meetings over the past 16 months, resulting in the preliminary recommendations summarized here.

Enlarged acetabular labra in the Pima Indians.

OBJECTIVE: To report the descriptive epidemiology of acetabular labral enlargement and analyze associations of other variables with this variant. METHODS: Pelvis radiographs from 761 Pima Indians aged > or = 45 years enrolled in a population based study were read by Kellgren-Lawrence global and individual radiographic features grading scales for osteoarthritis (OA) at separate settings. In total, 722 radiographs remained eligible for this study after excluding 12 unreadable radiographs and 27 cases of radiographic hip OA (Kellgren-Lawrence grade > or = 2). Enlarged acetabular labra were recorded during readings of individual radiographic features. RESULTS: Enlarged acetabular labra were present in 16% of study participants without OA and were significantly associated with female sex, but not with the variables age, body mass index, clinical hip joint involvement, diabetes, or serum insulin concentrations. CONCLUSION: Acetabular labral enlargement is common in the Pima Indians, and although not in excess of other reported acetabular margin anomalies, it differs in appearance and is not associated with age. Recognition of this structural variant is important because it can mimic fractures or osteophytes.
