Early undifferentiated connective tissue disease (CTD). VI. An inception cohort after 10 years: disease remissions and changes in diagnoses in well established and undifferentiated CTD.

OBJECTIVE: (1) To review the diagnoses after 10 years in patients who were identified within 12 months of the onset of well established and undifferentiated connective tissue diseases (CTD). (2) To examine the death rates and disease remissions in these patients. METHODS: This inception cohort of 410 patients had less than one year of signs and/or symptoms of CTD. Diagnoses of rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and poly/dermatomyositis (PM/DM) were made in 197 patients using accepted diagnostic and classification criteria. Diagnoses of undifferentiated CTD were made in 213 patients. These latter patients were placed in 3 categories: isolated Raynaud's phenomenon (RP), unexplained polyarthritis (UPA), and undifferentiated CTD (UCTD), defined as meeting at least 3 of 11 specific manifestations of CTD. The diagnoses and remissions in all patients after 10 years were determined. RESULTS: Patients with well established CTD tended to remain with the original diagnosis. The 10 year survival was at least 87% in all diagnostic categories, with the exception of SSc, in which it was 56%. The progression of UPA to RA occurred infrequently. The presence of antinuclear antibodies suggested that UPA may develop additional symptoms and/or a specific diagnosis, and RP in these patients increased the likelihood of progressing to UCTD or a specific well established CTD. Ten percent of patients with RP progressed to SSc. In patients with UCTD, joint pain/tenderness and swelling counts were associated with progression to other diagnoses including RA, while either serositis, malar rash, or discoid lupus suggested the eventual diagnosis of SLE. CONCLUSION: The survival of patients with SSc was poor, with most dying early in the course of their disease. Remissions were seen in all groups of patients except SSc. The remissions were sometimes transient in SLE. Undifferentiated disease at initial examination within 12 months of onset usually remains undifferentiated.

Early undifferentiated connective tissue disease. V. An inception cohort 5 years later: disease remissions and changes in diagnoses in well established and undifferentiated connective tissue diseases.

OBJECTIVE: To review the diagnoses after 5 years in patients who were identified within 12 months of the onset of well established and undifferentiated connective tissue diseases (CTD); to examine death rates and disease remissions in these patients. METHODS: This inception cohort of 410 patients was identified in 10 academic rheumatology practices. They had less than one year of signs and/or symptoms of CTD. Diagnoses of specific well established CTD were made using accepted diagnostic and classification criteria. The diagnoses after 5 years were determined. RESULTS: Patients with well established CTD tended to remain with the original diagnosis. The progression of unexplained polyarthritis to rheumatoid arthritis occurred infrequently. Ten percent of patients with isolated Raynaud's phenomenon progressed to systemic sclerosis (SSc). The 5 year survival was over 90% in all diagnostic categories, with the exception of SSc, in which it was 64%. CONCLUSION: Patients with a well established CTD usually continued with the same diagnosis. Patients with undifferentiated CTD tended to remain undifferentiated or to remit.

Early undifferentiated connective tissue disease. IV.Musculoskeletal manifestations in a large cohort of patients with undifferentiated connective tissue diseases compared with cohorts of patients with well-established connective tissue diseases: followup analyses in patients with unexplained polyarthritis and patients with rheumatoid arthritis at baseline.

OBJECTIVES: To examine the musculoskeletal manifestations in a large cohort of patients (n = 410) diagnosed with either a well-established connective tissue disease (CTD) (n = 197) or an early undifferentiated CTD (n = 213) with a symptom duration of <1 year. This study was aimed at determining the predictive value of demographic, clinical, and laboratory features on outcome in patients with unexplained polyarthritis (UPA) (from the early undifferentiated CTD cohort; n = 67) or rheumatoid arthritis (RA) (from the well-established CTD cohort; n = 57), over a 5-year followup period. METHODS: Patients from both cohorts were assessed at years 1, 3, and 5. At the study visits, clinical data were collected in a standardized manner, and sera were obtained and stored. A priori criteria were established for patient ascertainment and diagnosis over the duration of the study. Standard statistics were used for comparisons of baseline characteristics in patients diagnosed as having systemic lupus erythematosus, RA, undifferentiated CTD, and UPA at entry into the cohorts. Baseline features in patients with UPA were examined according to the different subsequent outcomes (RA, CTD, or undifferentiated CTD, remission [nonpersistent], or persistent or active UPA). Baseline features in patients with RA whose disease remained active versus those in whom remission was attained were also examined. Two multivariable analyses, classification trees and polychotomous logistic regression, were performed to predict disease outcomes over time. RESULTS: The overall rate of ascertainment for the 410 patients ranged from 90 % at year 1 to 71 % at year 5. Patients with established CTDs showed a tendency for more stable diagnoses than those with early undifferentiated CTDs (90-100% versus 45-70%). Consistent baseline predictors of persistent active disease among patients with RA, in both univariate and multivariable analyses, were higher joint counts for pain and tenderness and higher erythrocyte sedimentation rate (ESR). In approximately 20% of patients who were classified as having RA when they originally entered the cohort, the disease was in remission at 5 years. Twenty percent of the patients originally classified as having UPA developed RA over the duration of the study. These patients tended to be older and to have swelling of small joints at baseline. However, a consistent pattern of predictive variables could not be identified in the multivariable analyses, other than at year 1 (higher small joint counts for swelling and higher ESR). CONCLUSION: Baseline features (joint counts, and ESR) among RA patients were variously predictive of persistently active disease at years 1-5. Consistent baseline predictors of outcome among patients with UPA only emerged at year 1. Remission occurred in approximately 20% of RA patients, whereas a similar percentage of patients with UPA developed RA. These findings have implications with regard to treatment decisions in patients with early RA and/or UPA.

Early undifferentiated connective tissue disease: III. Outcome and prognostic indicators in early scleroderma (systemic sclerosis).

OBJECTIVE: To characterize the course of early scleroderma and to delineate prognostic factors present within 1 year of disease onset that might identify patients at high risk. DESIGN: Inception cohort study. SETTING: Ten university-based rheumatology clinics participating in the Cooperative Systematic Studies of Rheumatic Diseases Program. PATIENTS: Forty-eight patients who had had scleroderma for less than 1 year. MEASUREMENTS: Fifteen patients with early scleroderma who died were compared with those still living during the initial study period (1982 to 1992). Kaplan-Meier survival estimation and Cox proportional hazards analysis were used to analyze baseline variables for their ability to predict survival duration. RESULTS: Eight of 15 deaths were due to cardiac or pulmonary system failure. The estimated 5-year survival rate was 68%. Baseline factors that were the most predictive of a poor outcome included the presence of abnormal cardiopulmonary signs and abnormal urine sediment (pyuria, hematuria). CONCLUSION: Evidence of early cardiopulmonary disease, renal disease, inflammation, or immune activation may identify a subset of patients with scleroderma who will experience rapidly progressive disease and early death.

Autoantibodies and SLE.

Systemic lupus erythematosus is characterized by an enormous and increasing array of antibodies to cellular constituents. These autoantibody phenomena are not diagnostic in themselves but must be interpreted within the context of the individual clinical situation.

Intravenous pulsed steroids in rheumatoid arthritis: a comparative dose study.

This prospective, double blind study was undertaken to test the efficacy of intravenous "minipulse" (100 mg) methylprednisolone (MP) therapy versus standard pulse (1000 mg) MP therapy in rheumatoid arthritis (RA). Thirty-six patients with RA synovitis flares were randomized to receive either 100 or 1000 mg MP IV QD x 3 doses. These 2 universally comparable groups exhibited no statistically significant differences in their striking prompt and sustained clinical improvement. These data suggest that minipulse MP is as efficacious as conventional pulse MP in the treatment of RA flares.

Treating joint inflammation in the elderly: an update.

The abrupt onset of monoarthritis in an older patient--especially knee, but also wrist, elbow, ankle, or shoulder--should alert the clinician to the possibility of pseudogout. Joint damage or synovitis may predispose aged patients to sepsis. Rheumatoid synovium, for example, has altered synovial resistance to bacterial seeding; thus, septic arthritis in rheumatoid patients may be polyarticular.
