Arthritis Chronicle

Meloxicam is a nonsteroidal antiinflammatory drug, used in the treatment of rheumatoid arthritis and oestoarthritis. It is practically insoluble in water, leading to poor dissolution, variations in bioavailability, and gastric irritation on oral administration. In the attempt to reduce its gastric side effect and to increase aqueous solubility, physical mixture and solid dispersion of the drug were prepared with polyethylene glycol 6000. The analgesic, antiinflammatory, and ulcerogenic effects were assessed for physical mixture and solid dispersion in comparison with meloxicam alone. The results indicate that both physical mixture and solid dispersion possess better analgesic and antiinflammatory properties with less ulcerogenic potential when compared with pure meloxicam.

Objective: The patient-based evaluation of outcome is gaining increased importance. The aim of the study was to demonstrate the reliability, validity and responsiveness of the German version of the Short Musculoskeletal Function Assessment Questionnaire (SMFA-D) in patients undergoing surgical or conservative treatment.

Methods: Three hundred and thirty-two patients suffering from osteoarthritis of the hip or knee, rheumatoid arthritis or rotator cuff tear undergoing surgical or medical inpatient treatment were followed up for 12 month. Patients underwent both SMFA-D and other assessments and clinical as well as radiological examinations. Reliability, validity and responsiveness of the SMFA-D were evaluated.

Results: Values of the SMFA-D subscales, Function index (M 22-49, SD 12-20, range 0-96) and Bother index (M 29-52, SD 15-23, range 0-100), showed a normal distribution. Internal consistency (0.88-0.97) and retest reliability (0.71-0.96) coefficients were satisfactory to excellent. In most cases, the SMFA-D correlated significantly with function tests, physicians’ function ratings, patients’ pain ratings and other quality-of-life questionnaires in all patient subgroups. The results support both the construct and criterion validity of the measure. Different patient groups and subgroups could be discriminated with the SMFA-D scales. The standardized response means of SMFA-D subscales were in surgical patients better than in conservatively treated patients and comparable to those of the SF-36 Physical Component Summary scale. Conclusions: The German version of SMFA is a reliable, valid and responsive questionnaire in patients with osteoarthritis of the hip or knee, rheumatoid arthritis or rotator cuff tear undergoing surgical or medical inpatient treatment. Thus, the use of the SMFA-D in these patients can be recommended.

This paper comes from Strand et al in Norway.

The objective of the study was to analyze the relationships between Pain Readiness to Change, weekly measures of positive and negative affect and pain over eight subsequent weeks in patients with rheumatoid arthritis (RA). Factor analysis based on data from three different samples of patients with rheumatic diseases and other chronic pain conditions suggested a three factor solution for the Norwegian version of the Pain Stages of Change questionnaire (PSOCQ) representing Precontemplation, Contemplation, and Action/Maintenance (ACT) stages from the original Transtheoretical Model. Multilevel analyses on the weekly assessed data from a sub sample of 40 patients with RA revealed that higher levels of Pain Readiness to Change represented by high ACT scores were associated with more positive affect from week to week while no association was found between Readiness to Change and weekly pain. However, there was an interaction effect between Pain Readiness to Change and weekly positive affect on weekly pain, indicating that those persons having a higher level of Readiness to Change reported less pain in weeks when they also experienced increased positive affect. This may imply that a combination of cognitive factors and positive affect is most effective in relation to pain reduction.

Results encourage continued investigation of apparent interactions between chronic pain, affect, and pain self-management.
