RESUMEN
BACKGROUND: Uric acid has been related to a tendency to precipitate to form crystals, presenting asymptomatically, until the formation of arthritis, tophi or renal lithiasis. Previously, the presence of asymptomatic hyperuricaemia has been associated with the presence of cardiovascular disease. OBJECTIVES: To determine the association of complex coronary artery disease in patients with asymptomatic hyperuricaemia. MATERIAL AND METHODS: An observational retrospective, transversal, unicentric study was conducted in a tertiary hospital in Mexico, in the period from June 2017 to March 2019. All patients admitted for coronary angiography were included; patients with gout, use of diuretics and chronic kidney disease were excluded. RESULTS: During the study period, a total of 300 patients were collected, of which 40% presented hyperuricaemia. The patients with hyperuricaemia were older (59 vs. 63, P = .002). The group of patients with asymptomatic hyperuricaemia had a higher proportion of complex coronary lesions (64 vs. 35%, P ≤ .0001) as well as a higher SYNTAX I score (27 vs. 17, P ≤ .001). There was a higher probability of presenting complex coronary lesions in this group of patients (OR 3.4, P ≤ .0001). In addition, in the group division of uric acid levels, it was related to the presence of complex coronary lesions (Q1 = .5, P = .06), (Q2 = 2, P = .01) and (Q3 = 3, P ≤ .0001). CONCLUSION: Asymptomatic hyperuricaemia has a higher prevalence and association of presenting complex coronary lesions.
RESUMEN
BACKGROUND: In patients with systemic lupus erythematosus (SLE), left ventricle diastolic dysfunction (LVDD) may be the only manifestation of cardiac involvement in anticipation of systolic dysfunction. It has been seen that myocardial deformation of the left atrium (LA), through the LA global longitudinal strain (LAGLS), may be useful in assessing diastolic function. OBJECTIVE: To evaluate LA function through myocardial deformation in patients with LES, and compare the LA strain in patients with active, inactive and controls. METHODS: Fifty patients with SLE were included and compared with 50 healthy controls paired by age and gender. Myocardial deformation was measured by transthoracic echocardiogram, to investigate the LAGLS, the strain of the three phases of the LA cycle and the strain rate. The differences between groups were compared in univariate analysis. RESULTS: LAGLS in SLE patients was less than in the controls (41.6% vs. 50.5%; p=.02), and in the 3 phases of the LA cycle. There were no differences in the LA strain rate in both groups (SLE 2.5s-1 vs. controls 2.75s-1; p=.1). It was also found that the LAGLS was lesser in active patients than controls and inactive. CONCLUSIONS: SLE patients have lower myocardial deformation of the LA, which is expressed as a lower diastolic function correlating with early subclinical myocardial damage.
RESUMEN
OBJECTIVES: To update the recommendations for the management of patients with Spondyloarthritis (SpA) in the Mexican population, and identify which variables could influence patient management. MATERIAL AND METHODS: A group of 15 experts in SpA translated, analyzed and modified the recommendations of the Mexican College of Rheumatology (CMR) and the International Society for the Assessment of Spondyloarthritis (ASAS)/European League Against Rheumatism (EULAR) 2016 group through a systematic review of the literature by two external reviewers during the period from 2015 to 2018 using the grade of recommendation, Oxford levels of evidence, percentage of concordance (Delphi). RESULTS: Compared to previous recommendations, there were no significant changes from the year 2015. However, we modified the five fundamental principles and reduced the number of recommendations to ten by incorporating the first item in the text and combining five recommendations into two and adding a further recommendation. We confirmed the tendency to use glucocorticoids for patients with inflammatory activity and scarce access to biologicals. We identified the sociodemographic and clinical characteristics of patients with SpA and their influence on the application of the recommendations. CONCLUSIONS: The ten recommendations of the CMR and the analysis of the characteristics of the Mexican patients with SpA focussed on step therapy, including pharmacological and non-pharmacological therapies, in a spectrum from easily accessible to high-tech substances available to a small percentage of the population.
RESUMEN
The depressive symptoms are associated with chronic pain in this study. A cross-sectional study was performed. A visual analog scale was used to register pain intensity. Depressive symptoms were measured using the Center of Epidemiological Studies (CES-Dr) scale as modified by Eaton and reviewed for use in the Mexican population. The study included 245 patients, with a mean age of 46 years, 86.1% of whom were female. The prevalence of some degree of depression was 55.1%. Patients with fibromyalgia had the highest prevalence of symptoms of depression (78.38%) and major depression (29.73%). Stepwise multiple regressions indicated that the best model (r2 = 0.26) to predict the CES-Dr score included the global pain score (P < 0.0001) and education level (P < 0.004). The Cronbach's alpha of the CES-Dr was high (alpha = 0.888). There was moderate correlation (r = 0.442), P < 0.0001 of the CES-Dr numeric score with the intensity of global pain.

INTRODUCTION: Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovial membrane damage and autoantibody production. RA is a heterogeneous disease, where cytokines such as IL-15, IL-21, and IFN-γ have been associated. However, their association with the autoantibodies has not been clearly described. The aim of this study was to evaluate the relationship between the cytokines IL-15, IL-21, and IFN-γ with the autoantibodies (RF, anti-CCP, anti-MCV, and anti-PADI4) in RA and disease activity. METHODOLOGY: This study included 153 RA patients and 80 control subjects (CS). The levels of IL-15, IL-21, IFN-γ, anti-CCP, anti-MCV, and anti-PADI4 were quantified by ELISA, whereas RF was quantified by turbidimetry. The disease activity was evaluated by the indices disease activity score 28-erythrocyte sedimentation rate (DAS28-ESR), clinical disease activity index (CDAI), and simple disease activity index (SDAI). RESULTS: The serum levels of IL-15, IL-21, and IFN-γ, and autoantibodies were increased in RA patients, compared with CS (p < 0.05). A correlation was found between IL-21 and anti-CCP and anti-MCV (p < 0.05). According to RA evolution, RF, anti-CCP, and anti-MCV had higher levels in early RA. In addition, increased levels of IL-21 were observed in RA seropositive patients (RF/anti-CCP/anti-MCV). The higher levels of both cytokines and autoantibodies were observed in moderate activity, evaluated by the three indices. CONCLUSIONS: Our results suggest that the increased soluble levels of IL-15, IL-21, and IFN-γ are involved in the inflammatory network in RA. However, IL-21 serum levels are associated with higher titers of autoantibodies (RF, anti-CCP, and anti-MCV) and IL-15 with moderate activity. Key Points ⢠IL-15, IL-21, and IFN-y are associated with the immunopathology of RA, but not significantly with the evolution of the disease. ⢠RF, anti-CCP, and anti-MCV had higher levels in early than established RA. ⢠IL-21 has an association with RF, anti-CCP, and anti-MCVand, for this reason, could be proposed as a disease biomarker. ⢠Patients with activity moderate of disease showed higher levels of RF, anti-CCP, anti-MCV, and IL-15.

BACKGROUND: The pharmacologic management of rheumatoid arthritis has progressed substantially over the past years. It is therefore desirable that existing information be periodically updated. There are several published international guidelines for the treatment of rheumatoid arthritis that hardly adapt to the Mexican health system because of its limited healthcare resources. Hence, it is imperative to unify the existing recommendations and to incorporate them to a set of clinical, updated recommendations; the Mexican College of Rheumatology developed these recommendations in order to offer an integral management approach of rheumatoid arthritis according to the resources of the Mexican health system. OBJECTIVE: To review, update and improve the available evidence within clinical practice guidelines on the pharmacological management of rheumatoid arthritis and produce a set of recommendations adapted to the Mexican health system, according to evidence available through December 2012. METHODS: The working group was composed of 30 trained and experienced rheumatologists with a high quality of clinical knowledge and judgment. Recommendations were based on the highest quality evidence from the previously established treatment guidelines, meta-analysis and controlled clinical trials for the adult population with rheumatoid arthritis. RESULTS: During the conformation of this document, each working group settled the existing evidence from the different topics according to their experience. Finally, all the evidence and decisions were unified into a single document, treatment algorithm and drug standardization tables. CONCLUSIONS: This update of the Mexican Guidelines for the Pharmacologic Treatment of Rheumatoid Arthritis provides the highest quality information available at the time the working group undertook this review and contextualizes its use for the complex Mexican health system.
