[Disability in lupus erythematosus]

Morbidity and co-morbidities in patients with lupus erythematosus (LE) result in an impairment, limiting activities of daily living. We compared the handicap, appraised by the German welfare system in patients with LE and their diagnosis, morbidities and co-morbidities, therapy, functional capacity, psychological status and general health. The data were obtained in an anonymous self-administered questionnaire conducted by the lupus patient association. 892 data sets were available for the trial. The mean age was 46.9y, disease duration was 10.3y. The patients had 3.8 concomitant diseases on average. 39.7% were still working and 35.4% drew a pension. 59.2% made an application for disability, which wasn't assigned in only 2.5% of cases. 82.6% had an average grade of disability of more than 50%. It demonstrated a good correlation to age, disease duration, type of LE and therapy. Predictors for a worse assessment were disease duration, osteoarthritis, cerebral insults and functional capacity. In conclusion the data demonstrate a fair appraisal of disability by the German welfare system in patients with LE. Self-administered questionaires can yield credible results.
