Outcome evaluated according clinical characteristics, laboratory abnormalities, findings on routinely performed angiographic studies, and ability withdraw therapy. Eighteen patients entered study; 2 dropped out, 16 were followed up for a mean...
To examine the degree to which shared risk factors explain relationship of periodontitis (PD) rheumatoid arthritis (RA) and determine associations PD Porphyromonas gingivalis with pathologic clinical features RA.Patients RA (n = 287) patients osteoarthritis as disease controls 330) underwent a standardized periodontal examination. The HLA-DRB1 status all participants was imputed using single-nucleotide polymorphisms from extended major histocompatibility complex. Circulating anti-P...
Background: Similarities exist in the epidemiology and immunopathogenesis of periodontitis rheumatoid arthritis (RA), but associations between their respective disease activities severities are less well documented. We evaluated prevalence severity United States (U.S.) veterans with RA relationship to activity severity. Methods: Patients from an outpatient rheumatology clinic were eligible, patients osteoarthritis (OA) served as controls. Dentists, masked rheumatologic diagnoses, performed...
The co-occurrence of rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) positivity in arthritis (RA) is well described. However, the mechanisms underlying potential interaction between these 2 distinct autoantibodies have not been defined. aim this study was to evaluate epidemiologic molecular ACPAs RF its association with both disease activity measures RA-associated inflammation.In a cohort 1,488 US veterans RA, serum levels cytokines multiplex were compared following...
To assess the correlation and prognostic value of antineutrophil cytoplasmic antibody (cANCA) titers with disease activity in patients Wegener's granulomatosis (WG).One hundred six WG had serum ANCA determinations; 72 serial obtained routinely at 1-3-month intervals. One twelve subjects (19 whom were healthy donors) served as controls. All samples tested for cANCA by an indirect immunofluorescence technique. A prospective analysis values was performed. Disease assessed according to clinical,...
Abstract Objective . To determine the efficacy of low‐dose methotrexate (MTX) plus prednisone in treatment Wegener's granulomatosis (WG). Methods An open‐label study weekly MTX for WG was performed. Forty‐two patients who did not have immediately life‐threatening disease were enrolled into study. Outcome determined by clinical characteristics and pathologic, laboratory, radiographic findings. Results Weekly administration resulted remission 30 42 (71%). The median time to 4.2 months....
Abstract Objective . To identify alternatives to daily low‐dose cyclophosphamide (CYC) in the treatment of Wegener's granulomatosis (WG). Methods An open‐label pilot study weekly methotrexate (MTX) plus glucocorticoids (GC) for patients with WG was performed. Twenty‐nine who did not have immediately life‐threatening disease were included. Outcome determined by clinical characteristics, pathologic findings, course illness, laboratory and radiographic successful withdrawal GC therapy. Results...
Abstract Wegener's granulomatosis (WG) is a multisystem inflammatory disease characterized by vasculitis, granuloma formation, and necrosis. Among 158 patients treated at the National Institutes of Health during past 24 years, 145 (92%) had an otolaryngologic manifestation their 25 (16%) subglottic stenosis (SGS). SGS varied from asymptomatic to life‐threatening. Sixteen (80%) 20 with fixed required surgical intervention, including manual dilations, carbon‐dioxide laser resections,...
Objective. 25-hydroxy-vitamin D (25-OH-D) insufficiency/deficiency is increasingly prevalent and has been associated with many chronic diseases, including rheumatoid arthritis (RA). Our purpose was to define the prevalence associations of 25-OH-D in a cohort US veterans RA. Methods. Vitamin status assessed patients RA using radioimmunoassay on banked plasma collected at enrollment. Insufficiency defined as concentrations < 30 ng/ml deficiency 20 ng/ml. Associations patient characteristics...
There has been limited investigation into cause-specific mortality and the associated risk factors in men with rheumatoid arthritis (RA). We investigated all-cause RA, examining determinants of survival.Men from a longitudinal RA registry were followed enrollment until death or through 2013. Vital status cause determined using National Death Index. Crude rates standardized ratios (SMRs) calculated for all-cause, cardiovascular disease (CVD), cancer, respiratory mortality. Associations...
Abstract Objectives To determine whether RA and interstitial lung disease (ILD) severity measures are associated with survival in patients RA-ILD. Methods We studied US veterans RA-ILD participating a multicentre, prospective cohort study. activity (28-joint DAS [DAS28-ESR]) functional status (multidimensional HAQ [MDHAQ]) were collected longitudinally while pulmonary function tests (forced vital capacity [FVC], diffusing for carbon monoxide) obtained from medical records. Vital cause of...
Objective To evaluate the associations of plasma matrix metalloproteinases (MMPs) with prevalent and incident interstitial lung disease (ILD) in people rheumatoid arthritis (RA). Methods Within a multicenter, prospective cohort US veterans RA, we performed cross‐sectional study ILD ILD. diagnoses were validated by medical record review provider chest imaging and/or pathology reports. MMP‐1, 3, 7, 9 concentrations measured samples, then standardized categorized into quartiles. The MMPs...
