Low Frequency of Anticyclic Citrullinated Peptide Antibodies in Psoriatic Arthritis But Not in Cutaneous Psoriasis
[ PUBLICATION ]
BACKGROUND: Anticyclic citrullinated peptide (anti-CCP) antibodies are highly specific for the diagnosis of rheumatoid arthritis (RA). The clinical distinction between RA and psoriatic arthritis (PsA) is often difficult to establish; therefore, the presence of rheumatoid factor (RF) and anti-CCP antibodies could be useful. Seven percent to 40% of patients with longstanding psoriasis will develop PsA at some point. Therefore, it is important to study the positivity of these antibodies in ...

Effect of HLA-B and HLA-DR genes on susceptibility to and severity of spondyloarthropathies in Mexican patients
[ PUBLICATION ]
OBJECTIVE: To investigate the role of HLA-B and HLA-DR genes as contributors to genetic susceptibility and clinical expression of the spondyloarthropathies (SpA) in the Mexican population.
METHODS: The study included 172 patients with SpA (undifferentiated SpA 83, ankylosing spondylitis (AS) 64, and reactive arthritis 25) and 99 healthy controls. The HLA-B and HLA-DR alleles were detected by the polymerase chain reaction with sequence-specific primers technique. Patient assessment ...

OBJECTIVE: To evaluate the efficacy and safety of etoricoxib and indomethacin in the treatment of patients with acute gout.
METHODS: A randomized, double-blind, active-comparator study was conducted at 42 sites. A total of 189 men and women (> or =18 years of age) who were experiencing an acute attack (< or =48 hours) of clinically diagnosed gout were treated for 8 days with etoricoxib, 120 mg/day (n = 103), or indomethacin, 50 mg 3 times a day (n = 86). The primary efficacy end point ...

OBJECTIVE: To determine the rate and factors associated with ankylosing spondylitis in a cohort of patients with undifferentiated spondyloarthritides (SpA).
METHODS: 62 consecutive patients with undifferentiated SpA seen between 1998 and 1999 underwent clinical and imaging evaluations throughout follow up. The main outcome measure was a diagnosis of ankylosing spondylitis.
RESULTS: 50 patients with peripheral arthritis (n = 35) and inflammatory back pain (n = 24) (26 male; mean (SD) age ...

Use of a numerical rating scale as an answer modality in ankylosing spondylitis–specific questionnaires
[ PUBLICATION ]
OBJECTIVES: To determine the agreement of scores on the original visual analog scale (VAS) or Likert scale of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), and Dougados Functional Index (DFI) with scores on a numerical rating scale (NRS). To assess the reproducibility and responsiveness of the instruments with the original scale and NRS.
METHODS: Five hundred thirty-six patients with ankylosing spondylitis from the ...

Heat shock protein 70 gene polymorphisms in Mexican patients with spondyloarthropathies
[ PUBLICATION ]
OBJECTIVE: To investigate the role of HSP70 genes as contributors to genetic susceptibility of the spondyloarthropathies (SpA) in the Mexican population.
METHODS: The study included 150 patients with SpA (undifferentiated spondyloarthropathy (uSpA) 68, ankylosing spondylitis (AS) 60, and reactive arthritis 22) and 158 healthy controls. HSP70-1, HSP70-2 and HSP70-hom genotypes were analysed by the polymerase chain reaction-restriction fragment length polymorphism technique. Statistical ...

Analysis of HLA-B15 and HLA-B27 in spondyloarthritis with peripheral and axial clinical patterns
[ PUBLICATION ]
OBJECTIVE: Human leucocyte antigen (HLA) B27 and HLA-B15 are associated with spondyloarthritis (SpA). Recent Assessment of SpondyloArthritis international Society (ASAS) criteria emphasise a distinction between SpA with axial and peripheral patterns. We analysed whether HLA-A, HLA-B and HLA-DRB1 alleles could associate with these patterns.
METHODS: We studied 100 healthy individuals and 178 patients with SpA according to European Spondyloarthropathy Study Group (ESSG) criteria. Patients ...

Periodontal Disease in Individuals With a Genetic Risk of Developing Arthritis and Early Rheumatoid Arthritis: A Cross‐Sectional Study
[ PUBLICATION ]
BACKGROUND: Recent consensus emphasizes the importance of studying individuals at risk for rheumatoid arthritis (pre-RA) and those with early RA (eRA). Periodontal tissues have been recently evaluated, but these studies are limited. To evaluate the periodontal condition, immunoglobulin (Ig)G subclasses against Porphyromonas gingivalis in individuals with pre-RA and eRA were compared with controls to establish an association between periodontal infection markers and rheumatic ...

Tumor Necrosis Factor-α Promoter Polymorphisms in Mexican Patients With Spondyloarthritis
[ PUBLICATION ]
To evaluate the role of tumor necrosis factor-alpha (TNF-alpha) gene as susceptibility marker for spondyloarthritis (SpA), two polymorphisms (-238 and -308 positions) were analyzed in 229 patients with SpA (113 with ankylosing spondylitis [AS], 92 with undifferentiated SpA [U-SpA], 24 with reactive arthritis), and 169 ethnically matched healthy control subjects. The HLA-B alleles were detected by PCR-SSP technique and the TNF-alpha polymorphism by PCR-RFLP. In comparison with healthy ...

Introducción Las enfermedades reumáticas son causa frecuente de discapacidad, deterioran la calidad de vida y causan alto gasto en salud. El modelo COPCORD se ha implementado universalmente para estimar su prevalencia. El objetivo es estimar la prevalencia de las enfermedades reumáticas en la población colombiana mayor de 18 años. Métodos Se realizó un estudio de prevalencia utilizando un método probabilístico de muestreo aleatorio estratificado en 3 etapas: selección de los sectores ...

The objective of this study is to correlate the patient-driven tool Routine Assessment of Patient Index Data 3 (RAPID-3) with other common tools used in daily practice to measure disease activity in rheumatoid arthritis (RA).One hundred nineteen RA patients according to 1987 American College of Rheumatology criteria who consecutively attended a RA outpatient clinic between August and December 2015 were evaluated. Data was stored in an electronic form that included demographic ...

[ PUBLICATION ]
INTRODUCTION: The prevalence of osteoporosis in premenopausal women along with associated risk factors has not been well elucidated. Recent studies have shown that poverty is a risk factor for osteoporosis.
OBJECTIVE: To determine the prevalence of osteoporosis and its risk factors in a group of premenopausal women of poor economic background in Colombia.
MATERIALS AND METHODS: The study comprised 1483 women between 35 and 53 years of age with at least one risk factor for osteoporosis. ...

Association study of LMP gene polymorphisms in Mexican patients with spondyloarthritis
[ PUBLICATION ]
To evaluate the role of LMP (low molecular weight protein) genes as susceptibility markers for spondyloarthritis (SpA), LMP gene polymorphisms were analyzed in 223 Mexican patients with SpA (81 undifferentiated SpA [U-SpA], 117 with ankylosing spondylitis [AS], 25 with reactive arthritis) and in 139 ethnically matched healthy individuals. LMP genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism. The LMP2 and LMP7 allele frequencies were similar ...
