Prevalence of Poor Sleep Quality and Associated Factors in Individuals with Rheumatoid Arthritis: A Cross-Sectional Study.

Background and Objectives: Poor sleep quality has been frequently observed in individuals with rheumatoid arthritis. In the present study, we analyzed the presence of poor sleep quality in a sample of Mexican individuals with rheumatoid arthritis; then, we compared sociodemographic and clinical characteristics among patients to determine risk factors for poor sleep quality. Materials and Methods: In this cross-sectional study, we included 102 individuals with rheumatoid arthritis from a hospital in Mexico. We evaluated disease activity (DAS28), quality of sleep using the Pittsburgh Sleep Quality Index, and the presence of depression and anxiety with the Hospital Anxiety and Depression Scale. We performed a Chi-square test and a t-test. Then, we performed a logistic regressions model of the associated features in a univariable analysis. Results: Poor sleep quality was observed in 41.75% of the individuals with rheumatoid arthritis. Being married was a proactive factor (OR 0.04, 95% CI 0.1-0.9, p = 0.04), whereas having one's hips affected or presenting with anxiety and depression was associated with poor sleep quality (OR 4.6, 95% CI 1.2-17.69, p = 0.02). After a multivariate analysis, having anxiety (OR 5.0, 95% CI 1.4-17.7, p < 0.01) and depression (OR 9.2, 95% CI 1.0-8.1, p < 0.01) remained associated with a higher risk of having poor sleep quality. Other clinical characteristics among patients were not significantly different. Conclusions: Our results showed that individuals with rheumatoid arthritis who also presented with depression or anxiety had a higher risk of suffering from poor sleep quality. However, more studies with larger samples are necessary to replicate these results in the Mexican population.

Relación entre las concentraciones de la leptina y la actividad de la enfermedad en pacientes con artritis reumatoide / Relationship between leptin concentrations and disease activity in patients with rheumatoid arthritis

Introducción y objetivo: Múltiples estudios han encontrado una relación directa entre las concentraciones de leptina y la actividad de la enfermedad en artritis reumatoide. Pacientes y métodos: Se estudiaron 77 pacientes con artritis reumatoide, la determinación de la leptina fue a través de inmunoanálisis enzimático. Se evaluó la actividad de la enfermedad mediante el DAS-28 PCR. Se realizó un modelo de regresión logística multivariante para determinar la asociación entre las variables significativas y las concentraciones de leptina. Resultados: El 40,3% de los pacientes estaban en remisión, el 41,6% actividad leve, el 11,7% actividad moderada y el 6,5% actividad grave. Se encontró una relación independiente entre mayores concentraciones de leptina y la actividad de la enfermedad (RR 1,7; IC al 95%: 1,4-3,2; p = 0,03), el número de articulación tumefactas (RR 4,6; IC al 95%: 1,7-8,3; p = 0,000), el número de articulaciones dolorosas (RR 3,4; IC al 95%: 1,6-4,6; p = 0,000) y a presencia de síndrome metabólico (RR 1,3; IC al 95%: 1,2-1,9; p = 0,045). Conclusiones: Los datos obtenidos sugieren que la leptina sérica está elevada en pacientes con AR activa

Background and objective: Multiple studies have found a direct relationship between leptin concentrations and disease activity in rheumatoid arthritis. Patients and methods: We studied 77 patients with the diagnosis of rheumatoid arthritis; the leptin determination was through an enzyme immunoassay. Disease activity was assessed by the DAS-28 CRP. A multivariate logistic regression model was used to determine the association between significant variables and leptin concentrations. Results: 40.3% of the patients were in remission, 41.6% were mildly active, 11.7% were moderately active and 6.5% were severely active. The results show an independent association between higher concentrations of leptin and disease activity (OR 1.7; 95% CI 1.4-3.2; p .03), the number of swollen joints (OR 4.6; 95% CI 1.7-8.3; p .000), the number of painful joints (OR 3.4; 95% CI 1.6-4.6; p .000), and the presence of metabolic syndrome (OR 1.3; 95% IC 1.2-1,9; p .045). Conclusion: The data suggest that serum leptin is elevated in patients with active RA

Dislipidemia y riesgo aterogénico en pacientes con lupus eritematoso sistémico / Dyslipidaemia and atherogenic risk in patients with systemic lupus erythematosus

Introducción: La dislipidemia es una comorbilidad frecuente en los pacientes con lupus eritematoso sistémico. Pacientes y métodos: Se incluyeron 51 pacientes. Se registraron variables asociadas a la enfermedad y los fármacos empleados. Se calculó el riesgo aterogénico. Se empleó la prueba de Chi cuadrado para las variables categóricas. Se realizó ANOVA y un modelo de regresión logística para determinar la asociación de las variables con la presencia de dislipidemia. Resultados: El 68,6% presentó dislipidemia. Se encontró diferencia significativa entre la presencia de dislipidemia y el índice de actividad medido por SLEDAI, la presencia de nefropatía lúpica, el uso de prednisona ≥ 20 mg/día, la evolución de la enfermedad < 3 años y entre la ausencia de dislipidemia y el empleo de hidroxicloroquina. SLEDAI ≥ 4 y el uso de prednisona ≥ 20 mg/día se asociaron independientemente con la presencia de dislipidemia. La media del índice de Castelli fue de 5,02, la del de Kannel fue de 2,97 y la de triglicéridos/c-HDL fue de 5,24. Conclusiones: Los pacientes con lupus eritematoso sistémico presentan una gran prevalencia de dislipidemia y un alto índice aterogénico, lo cual aumenta el riesgo cardiovascular (AU)

Introduction: Dyslipidaemia is a common comorbidity in patients with systemic lupus erythematosus. Patients and methods: Fifty-one patients were included. Variables associated with the disease and the drugs used were recorded. Atherogenic risk was calculated. Chi square was used for categorical variables. ANOVA was performed and a logistic regression model to determine the association of the variables with the presence of dyslipidaemia. Results: A percentage of 68.6 had dyslipidaemia. A significant difference between the presence of dyslipidaemia and activity index measured by SLEDAI was found, the presence of lupus nephritis, use of prednisone ≥ 20 mg/day, evolution of the disease < 3 years. Significance between the absence of dyslipidaemia and use of hydroxychloroquine was found. SLEDAI ≥ 4 and the use of prednisone ≥ 20 mg/day were independently associated with the presence of dyslipidaemia. The average of Castelli rate was 5.02, the Kannel index was 2.97 and triglyceride/HDL-C ratio was 5.24. Conclusions: Patients with systemic lupus erythematosus have a high prevalence of dyslipidaemia and a high atherogenic rate, which increases cardiovascular risk significantly (AU)

Dislipidemia y riesgo aterogénico en pacientes con artritis reumatoide / Dyslipidemia and atherogenic risk in patients with rheumatoid arthritis

Introducción: Los pacientes con artritis reumatoide tienen 2 a 3 veces mayor riesgo cardiovascular; se debe en parte al patrón de los lípidos los cuales aumentan el índice aterogénico. Métodos: Se incluyó a 82 pacientes, a quienes se les determinó el perfil lipídico. Se registraron variables asociadas a la enfermedad y los fármacos empleados. Se calculó el riesgo aterogénico. Se empleó la chi al cuadrado para las variables categóricas y la prueba de Mann-Whitney para las continuas. Se realizó ANOVA para determinar relación entre las medias del perfil lipídico y un modelo de regresión logística para determinar la asociación de las variables con la presencia de dislipidemia. Resultados: El 54,9% presentó dislipidemia. Se encontró diferencia significativa entre la presencia de dislipidemia y factor reumatoide positivo (p = 0,005), obesidad (p = 0,007), remisión de la enfermedad (p = 0,037) y PCR mayor or igual a 2 mg/dl (p = 0,024); no se encontró diferencia significativa entre la presencia de dislipidemia y el género, la edad y la evolución de la enfermedad. La obesidad (RR 4,79, IC del 95%, 1,5-5,1; p = 0,008) se asoció independientemente a la presencia de dislipidemia. El uso de hidroxicloroquina (RR 0,31, IC del 95%, 0,1-0,92; p = 0,035) se asoció independientemente a la ausencia de dislipidemia. La media del índice aterogénico de Castellí fue 4,36, la del índice de Kannel fue 2,59 y la del índice triglicéridos/c-HDL fue 3,83. El 61% presentó síndrome metabólico. Conclusiones: Los pacientes con artritis reumatoide presentan un perfil de lípidos proaterogénico; es importante conocerlo y tratarlo para disminuir el riesgo cardiovascular

Introduction: Dyslipidaemia is one of the main risk factors for atherosclerotic cardiovascular disease. Patients with rheumatoid arthritis have 2-3 times more cardiovascular risk, which is partly due to the pattern of lipids which increase the atherogenic index. Methods: A descriptive, cross-sectional, observational and prospective study was conducted on 82 patients, selected for their lipid profile. Variables associated with the disease and the drugs used were recorded. Atherogenic risk was calculated, with Chi square being used for categorical variables, and the Mann-Whitney test for the continuous ones. Results: The dyslipidaemia frequency was 54.9%. The most frequent age range of dyslipidaemia was between 51 and 60 years. Patients with type i obesity had a higher frequency of dyslipidaemia. Less dyslipidaemia was found with a lower rate of disease activity. Patients with cyclic citrullinated anti-peptide antibodies and positive rheumatoid factor, erythrocyte sedimentation rate > 13 mm or CRP > 2 mg/L had a higher frequency of dyslipidaemia. The mean Castelli atherogenic index was 4.36, the index of Kannel was 2.59, and triglycerides/HDL-c ratio was 3.83.Patients with dyslipidaemia showed a higher frequency of positive rheumatoid factor (P=.0008), and those patients who were taking hydroxychloroquine had a lower frequency of dyslipidaemia P=.03. Conclusions: Patients with rheumatoid arthritis have a pro-atherogenic lipid profile. It is important to know this and treat it to reduce cardiovascular risk

Circulating vascular endothelial growth factor concentrations in a case of pulmonary hypertrophic osteoarthropathy. Correlation with disease activity.

Vascular endothelial growth factor (VEGF) is a cytokine overexpressed in hypoxic and malignant pathologies. VEGF induces vascular hyperplasia, new bone formation, and edema. These histological abnormalities characterize hypertrophic osteoarthropathy. We describe a case of pulmonary hypertrophic osteoarthropathy with high circulating VEGF levels. Removal of the lung tumor led to a dramatic disappearance of the skeletal abnormalities and to reduction of circulating VEGF levels. Histochemical studies of the excised tumor confirmed abnormal VEGF production.
