Early remission of rheumatoid arthritis by 28-joint Disease Activity Score<2.6 was as frequent or more frequent in this study than in most previous reports. Importantly, women had more severe disease with a considerably lower remission rate than men, although the disease activity before treatment seemed similar.
Suggesting a holistic approach to rheumatology care, the study results indicate that the illness and outcomes have to be evaluated within an individual RA patient's total life situation, described in the identified themes: 'Normal life', 'Physical capacity', 'Independence' and 'Well-being'. Development and validation of measurements covering these issues is suggested. More research is needed about communication and how patients experience their roles in the rheumatology clinic.
Despite a similar degree of radiographic joint destruction women had, compared with men, worse scores for DAS28 and HAQ, possibly due to higher pain perception and less muscular strength and perhaps because men overestimate their functional capacity.
Pool exercise therapy of moderate intensity significantly improved muscle endurance in the upper and lower extremities in patients with RA, while no impact on aerobic capacity was found. However, the study population was small and there is a need for further studies with larger populations.
A technique for assessing the overall consequences of disease is introduced, comprising a Swedish version of a behaviour-based measure, the Sickness Impact Profile (SIP). Measurement characteristics of the profile are defined in an epidemiological study of 147 women with rheumatic disorders. The drop-out rate was 7.5%. Cross-cultural evidence of the validity of the SIP was obtained in this study. Test-retest reliability was substantial. A high level of validity of the Swedish version was demonstrated, as assessed by hypothesized significant relationships with selected functional, psychological, and social correlates. The profile was able to describe the various sickness impacts in a specific and sensitive manner. In the epidemiological setting, the subscales representing Ambulation, Body care and movement, Emotional behaviour, Social interaction, Sleep and rest, Home management and Recreation and pastimes, all showed discriminatory capacity. The categories Mobility, Alertness behaviour, Communication, Work, and Eating discriminated less well. The response pattern was recognizably related to rheumatic complaints, emphasizing a broader applicability of this scale in rheumatology.
Toxic epidermal necrolysis with epidermal shedding over almost the entire body occurred in a patient with classical rheumatoid arthritis treated with sulindac, penicillamine and a combination analgesic containing paracetamol and chlormezanone. Erosions in the lower respiratory tract and the intestine contributed to a lethal outcome of the disease and showed a microscopical picture similar to that of the skin involved. The histopathological picture of these extracutaneous lesions have been only briefly reported previously.
Twenty-two patients with amyloidosis secondary to rheumatoid arthritis were randomised and followed prospectively in order to determine whether treatment with cytotoxic drugs could postpone the development of end-stage renal failure. The diagnosis of amyloidosis was based on albuminuria, amyloid-positive rectal and/or abdominal fat aspiration and/or renal biopsies. Renal function was followed by repeated 51Cr-EDTA measurements of the glomerular filtration rate (GFR). Urinary albumin and serum-creatinine were found unreliable as predictors of renal function. GFR declined more rapidly in the patient group receiving only symptomatic drugs and no cytotoxic drugs (NT-group). After an initial decline, the GFR in the cytotoxic drug treatment group (T-group), mean treatment quotient 79%, levelled off and remained constant for a considerable time. The mean observation time was 45.7 months in the NT-group and 53.5 months in the T-group. Seven out of eleven patients in the NT-group developed end-stage renal disease, compared to two out of eleven patients in the T-group. The cumulative proportion of survivors in the NT-group at 36 and 60 months was 71% and 27% respectively. The corresponding figures in the T-group were 89% and 89%. The difference in favour of the cytotoxic drug-treated group was significant (p less than 0.04).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
