Ajg. Swaak et al., Systemic lupus erythematosus: clinical features in patients with a diseaseduration of over 10 years, first evaluation, RHEUMATOLOG, 38(10), 1999, pp. 953-958
Objective. Most information available about the disease course of patients
with systemic lupus erythematosus (SLE) is restricted to the first 5 yr aft
er disease onset. Data about the disease course 10 yr after disease onset a
re rare. The aim of this multicentre study was to describe the outcome of S
LE patients with a disease duration of >10 yr.
Methods. Outcome parameters were the SLE Disease Activity Index (SLEDAI); t
he European Consensus Lupus Activity Measure (ECLAM), the Systemic Lupus In
ternational Collaborative Clinics/American College of Rheumatology Damage I
ndex (SLICC/ACR), a global damage index (DI) and required treatment. In 10
different European rheumatology centres, all SLE patients who were evaluate
d in the last 3 months of 1994, and who had been diagnosed with SLE at leas
t 10 yr ago, were included in the study.
Results. It should be stressed that our results are confined to a patient c
ohort, defined by a disease duration of at least 10 yr, and who are still u
nder clinical care at the different centres in Europe. These SLE patients s
till showed some disease activity, related to symptoms of the sl;in and mus
culoskeletal systems, next to the presence of renal involvement. A total of
72% of the patients needed treatment with prednisolone (less than or equal
to 7.5 mg). The cumulative damage was overall related to clinical features
of the central nervous system (14%) and renal involvement (14%), next to d
eforming arthritis (14%), osteoporosis (15%) and hypertension (40%). The pr
evalences of obesity, Gushing appearance and diabetes are highly suggestive
that the ongoing treatment and that in the past might have had an impact o
n the total sum of endorgan damage.
Conclusions. After 10 yr, a high proportion of patients in our cohort conti
nued to show evidence of active disease, defined by the SLEDAI as well as E
CLAM. The DI was related to the involvement of the central nervous system,
renal involvement and the presence of hypertension.
