The effects of treatment counseling or symptom monitoring telephone intervention strategies on the health outcomes of patients with rheumatoid arthritis (RA) or osteoarthritis (OA), compared with usual care, were assessed.
                A 3-group, randomized, controlled 9-month trial was conducted incorporating 405 patients with RA or OA and using the Arthritis Impact Measurement Scales (AIMS2) as the outcome measure.
                Analyses of covariance showed that the AIMS2 total health status of the treatment counseling group (effect size = 33, P < 0.01), but not the symptom monitoring group (effect size = 0.21, P = 0.10), was significantly improved, compared with usual care, for both RA and OA patients. The specific types of benefits differed significantly between RA and OA patients. The mean number of medical visits by OA patients in the treatment counseling group was also significantly reduced (P < 0.01).
                Telephone contact using the treatment counseling strategy produced significant, but different, health status benefits for RA and OA patients. The symptom monitoring strategy produced modest benefits. Previous studies suggest a potential benefit from nonsteroidal anti-inflammatory drugs (NSAIDs) in Alzheimer's disease (AD). Prescribing NSAIDs, however, carries the risk of significant gastrointestinal adverse events.
                To study whether treatment with an NSAID prevents expected decline in AD patients and evaluate whether co-administration of the gastro-protective agent, misoprostol, with an NSAID is safe in AD.
                The efficacy and safety of diclofenac in combination with misoprostol (D/M) was evaluated in 41 patients with mild-moderate AD in a prospective 25-week, randomized, double-blind placebo-controlled trial. Efficacy measures comprised the Alzheimer's Disease Assessment Scale cognitive and noncognitive subsections, Global Deterioration Scale, Clinical Global Impression of Change, Mini-Mental State Examination, Instrumental Activities of Daily Living, Physical Self-Maintenance Scale, and a caregiver-rated Global Impression of Change.
                There were no group differences with any of the outcome measures in an intent-to-treat analysis. There were some nonsignificant trends for the placebo group to have deteriorated more than the D/M-treated patients. Withdrawal rates were 12 of 24 in the D/M group and 2 of 17 in the placebo group. There were no serious drug-related adverse events.
                This pilot study, with small treatment numbers, did not demonstrate a significant effect of NSAID treatment in AD, but the trends observed justify further investigations with a larger number of participants. D/M is safe in AD patients, but its tolerability is not optimal. In rheumatoid arthritis (RA) benefit from non-steroidal anti-inflammatory drugs (NSAIDs) is mediated through inhibition of the cyclo-oxygenase enzyme, thereby decreasing production of the 2 series prostaglandins (PGs). The lipoxygenase enzyme is intact, however, allowing leucotriene (LT) production, e.g., LTB4 (an inflammatory mediator). Treatment with evening primrose oil (EPO) which contains gamma-linolenic acid (GLA) leads to production of the 1 series PGs, e.g., PGE1, which has less inflammatory effects. Also LT production is inhibited. Eicosapentaenoic acid (EPA, fish oil) treatment provides a substrate for PGs and LTs, which are also less inflammatory. In this study 16 patients with RA were given 540 mg GLA/day (EPO), 15 patients 240 mg EPA and 450 mg GLA/day (EPO/fish oil), and 18 patients an inert oil (placebo). The aim of this study was to determine if EPO or EPO/fish oil could replace NSAID treatment in RA. The initial 12 month treatment period was followed by three months of placebo for all groups. Results at 12 months showed a significant subjective improvement for EPO and EPO/fish oil compared with placebo. In addition, by 12 months the patients receiving EPO and EPO/fish oil had significantly reduced their NSAIDs. After 3 months of placebo those receiving active treatment had relapsed. Despite the decrease in NSAIDs, measures of disease activity did not worsen. It is suggested that EPO and EPO/fish oil produce a subjective improvement and allow some patients to reduce or stop treatment with NSAIDs. There is, however, no evidence that they act as disease modifying agents. Peripheral arterial disease (PAD) is strongly associated with endothelial dysfunction and inflammation, which portend a high cardiovascular risk. Accordingly, we investigated the effects of omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation on endothelial function and inflammatory status in affected individuals.
                PAD patients were randomly divided into two groups. In Group I (n=16) pre-enrollment therapy was not modified, while in Group II (n=16) n-3 PUFAs 1 g b.i.d. for 3 months were added to the previous treatment. Endothelial function was assessed by measuring plasma soluble thrombomodulin (sTM) and brachial artery flow-mediated dilation (FMD), and the inflammatory status by measuring high-sensitivity C-reactive protein and myeloperoxidase.
                In Group II, n-3 PUFAs reduced sTM levels from the median value of 33.0 ng/mL (interquartile range 16.7, 37.2) to 17.0 ng/mL (11.2, 33.7) (p=0.04), and improved FMD from 6.7% (3.7, 8.7) to 10.0% (6.2, 14.2) (p=0.02). Conversely, these markers did not change in Group I. After 3 months, the levels of inflammatory markers remained unmodified in both groups.
                In PAD, n-3 PUFAs induced a marked improvement in endothelial function. Conversely, they did not affect the inflammatory status. In future, large, prospective studies are needed to investigate whether n-3 PUFAs, by improving endothelial function, would reduce the incidence of ischemic events in a population at high risk. The efficacy and safety of the oral gold compound auranofin and intramuscular gold thiomalate have been compared in a placebo-controlled, double-blind, four-centre trial in 82 patients with psoriatic arthritis requiring remittive drug therapy. There were statistically significant falls in Ritchie articular index, visual analogue pain score and ESR at 12 and 24 weeks following i.m. gold but no significant changes in the auranofin group. Intramuscular gold was safe and more effective than auranofin as a second-line, suppressive antirheumatic agent for patients with psoriatic arthritis when followed for 6 months. A beneficial effect of selegiline (L-deprenyl) in Alzheimer's disease (AD) has been reported in several clinical studies.
                The brain tissue from 17 deceased patients, members of a double-blind clinical trial to assess the potential benefit of selegiline in AD, were analysed.
                In our study, the decrease in the Mini-Mental State Examination (MMSE) scores during the progress of the disease had been significantly influenced by selegiline treatment. Prior to death, the MMSE scores were significantly higher in those patients receiving selegiline than in those receiving placebo. However, according to our results, none of the lesions critical for AD diagnosis, such as counts of senile/neuritic plaques, neurofibrillary tangles or beta-A4 load, were influenced by the selegiline treatment.
                In conclusion, according to our study, mechanisms other than neuronal degeneration seen as lesions critical for AD diagnosis are influenced by selegiline treatment, leading to the functional benefit found in AD. Type 2 diabetes mellitus is associated with elevated plasma triglyceride levels, low high-density lipoprotein cholesterol, and a high incidence of cardiovascular disease. Hydroxymethylglutaryl-coenzyme A reductase inhibitors and fibrates are frequently used in the treatment of diabetic dyslipidemia, but their specific impact on the inflammation processes involved in atherosclerosis remains to be fully characterized. The objective of this 2-group parallel study was to investigate the differential effects of a 6-week treatment with either atorvastatin 20 mg/d alone (n = 19) or micronized fenofibrate 200 mg/d alone (n = 19) on inflammation, cell adhesion, and oxidation markers in type 2 diabetes mellitus subjects with marked hypertriglyceridemia. In addition to the expected changes in lipid levels, atorvastatin decreased plasma levels of C-reactive protein (-26.9%, P = .004), soluble intercellular adhesion molecule 1 (-5.4%, P = .03), soluble vascular cell adhesion molecule 1 (-4.4%, P = .008), sE-selectin (-5.7%, P = .02), matrix metalloproteinase 9 (-39.6%, P = .04), secretory phospholipase A(2) (sPLA(2)) (-14.8%, P = .04), and oxidized low-density lipoprotein (-38.4%, P < .0001). On the other hand, fenofibrate had no significant effect on C-reactive protein levels and was associated with reduced plasma levels of sE-selectin only (-6.0%, P = .04) and increased plasma levels of sPLA(2) (+22.5%, P = .004). These results suggest that atorvastatin was potent to reduce inflammation, oxidation, and monocyte adhesion in type 2 diabetes mellitus subjects with marked hypertriglyceridemia, whereas fenofibrate decreased sE-selectin levels only and was associated with an elevation of sPLA(2) levels. Several lines of evidence suggest a role of inflammatory processes in Parkinson disease, although it is still unclear whether inflammation is a cause or rather a consequence of neurodegeneration.
                In a prospective population-based cohort study among 6,512 participants aged >or=55 years, with repeated in-person examination, we evaluated the association between cumulative use of nonsteroidal anti-inflammatory drugs (NSAIDs) and the risk of Parkinson disease. Complete information on filled prescriptions was available from automated pharmacy records. Data were analyzed by means of Cox proportional hazards regression analysis, adjusted for age, sex, smoking habits and coffee consumption.
                After an average 9.4 years of follow-up, 88 new cases of Parkinson disease were detected. No association was found between use of NSAIDs and the risk of Parkinson disease (adjusted hazard ratio for any NSAID use, 1.50; 95% confidence interval, 0.95-2.37).
                Our findings do not support the hypothesis that NSAIDs might decrease the risk of Parkinson disease.
                (c) 2007 S. Karger AG, Basel. Inflammation and oxidative stress have been implicated as pathogenic mechanisms in Parkinson's disease (PD). Evidence from in vitro and animal studies suggests a possible protective role of nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin. We investigated the risk of PD associated with use of aspirin and nonaspirin NSAIDs in a population-based case-control study among enrollees of Group Health Cooperative, a health maintenance organization in the Seattle area. Subjects included 206 cases between ages 35 and 89 with a new diagnosis of idiopathic PD between 1992 and 2002, and 383 randomly selected controls frequency-matched by age, sex, duration of enrollment, and clinic. We obtained information on participants' age, smoking, and medical history from interview. Exposure to NSAIDs was ascertained from an automated pharmacy database. Medications filled within 5 years of the interview were excluded. After adjusting for age, sex, smoking, duration of enrollment, and clinic, the risk of PD among individuals who received nonaspirin NSAIDs between 1977 and 1992 was 0.90 (95% CI: 0.59-1.35) and 1.67 (95% CI: 0.60-4.60) between 1993 and 2002. Use of ibuprofen was not associated with PD (OR: 0.89; 95% CI: 0.60-1.32). The risk of PD associated with aspirin or aspirin-containing medications was 0.74 (95% CI: 0.49-1.12). We observed no trend in risk according to number of fills for these drugs. Our results provide only limited support for the hypothesis that use of aspirin may reduce the risk of this disease, and no indication of protection from other NSAIDs.

There is 'gold' level evidence that AD has no benefit for undiscriminated OA (mechanical or inflammatory causes).
