G. Lamontagna et al., QUALITY-OF-LIFE ASSESSMENT DURING 6 MONTHS OF NSAID TREATMENT [GONARTHROSIS AND QUALITY-OF-LIFE (GOAL) STUDY], Clinical and experimental rheumatology, 16(1), 1998, pp. 49-54
Objective To identify the time point of the greatest degree of improve
ment in daily living activities, pain and depression in patients with
osteoarthritis (OA) of the knee during 6 months of treatment with NSAI
Ds, in order to define compliance and drop-out rate. Methods 107 patie
nts were recruited into a multicentre, prospective, randomized, contro
lled trial comparing two treatments, piroxicam-beta-cyclodextrin (PBCD
) and slow release diclofenac (DCL). Results The greatest improvement
in quality of life occurred in both groups after 3 months, with a slig
ht further gain observed by the end of treatment. The Stanford Health
Assessment Questionnaire score improved (p < 0.05 vs baseline) at 3 an
d 6 months with PBCD and at 6 months with DCL. The Arthritis Impact Me
asurement Scale score improved (p < 0.05 vs baseline) after 6 months i
n both groups. Significant (p < 0.05 vs baseline) improvement in other
psychological and pain scores were recorded in both groups after 3 an
d 6 months. Compliance with treatment at 3 months was 73% for PBCD and
72% for DCL, and was 60% in both groups at 6 months. Conclusions The
results of this study indicate that the optimal length of time for an
NSAID trial in OA patients is 3 months, when assessment of daily livin
g activities is considered as the main outcome criterion.
