OBJECTIVE To identify the frequency of serologic activity in the face of clinical quiescence in a large cohort of patients with systemic lupus erythematosus (SLE) followed prospectively in a single center. METHODS In a prospective cohort study, patients serologically active but clinically quiescent (SACQ) in 3 consecutive clinic visits were analyzed for the development of a clinical flare over the subsequent year and were evaluated for predictive factors for flare before and during their SACQ period. RESULTS Forty-six episodes of SACQ went on to clinical flare within one year while 60 did not. No predictive factors for flare were found either during or before the SACQ period. CONCLUSIONS A significant population of patients with SLE are SACQ and must be followed over time and treated only on the basis of clinical criteria.

UI MeSH Term Description Entries
D008180 Lupus Erythematosus, Systemic A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

D015331 Cohort Studies Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
