ABSTRACT
OBJECTIVE: Previous studies have reported a link between metabolic parameters and disease activity in rheumatoid arthritis (RA), although the evidence is limited in early RA. We aimed to investigate the relationship between disease activity and adipocytokine levels in subjects with early RA. METHODS: Forty-seven patients with early RA (symptom duration ≤12 months) were enrolled. Disease activity was determined by DAS28-CRP. Patients were treated with DMARDs according to the EULAR recommendations. Subjects were tested before and five months after treatment. RESULTS: Early RA patients with high disease activity (DAS28-CRP > 4.9) had greater BMI (31.2 ± 6.8 kg/m2 vs. 26.7 ± 4.1 kg/m2; p = 0.006) and higher leptin levels (14.62 ± 15.60 ng/mL vs. 7.82 ± 8.00 ng/mL; p = 0.048). Levels of other adipocytokines were not significantly different. Leptin levels were similar in subjects with mild/moderate disease activity and controls. DAS28-CRP was correlated with leptin (r = 0.303, p = 0.039). Leptin levels decreased significantly after treatment (from 10.86 ± 12.34 ng/mL to 9.22 ± 9.29 ng/mL; p = 0.047) along with insulin levels (from 13.68 ± 21.90 mU/L to 7.09 ± 4.72 mU/L; p = 0.010) and HOMA-IR (from 4.39 ± 9.53 to 1.70 ± 1.38; p = 0.012). HDL cholesterol levels increased (from 41 ± 10 mg/dL48 ± 10 mg/dL; p <0.001). CONCLUSION: Leptin levels were associated with disease activity in patients with early RA and these levels decreased after treatment with DMARDs. Further research is needed to elicit leptin's role to regulate disease activity in early RA.

Systemic sclerosis (SSc) may overlap frequently with other rheumatic diseases, including systemic lupus erythematosus (SLE), which can require high-dose steroids depending on the clinical presentation. We present a case involving this overlap in which the patient concomitantly developed lupus nephritis and Coombs (+) hemolytic anemia, which was confused with scleroderma renal crisis. In this condition, assessing for lupus nephritis with timely renal biopsy and lupus serology can aid in guiding the appropriate treatment. We discuss the clinical features and challenging management of this case with a review of the English-language literature for SSc and SLE overlap with glomerulonephritis.

INTRODUCTION: Cardiovascular diseases (CVD) are one of the most common causes of mortality in chronic kidney disease. Smoking is a well defined risk factor for atherosclerotic cardiovascular disease. Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), high sensitive C-reactive protein (hsCRP) and endothelin-1 (Et-1) have found elevated in chronic inflammatory process. OBJECTIVE: We aimed to evaluate if IL-6, TNF-alpha, hsCRP and ET-1 are increased in smoker hemodialysis (HD) patient compared to non-smoker HD individuals to potentially refer us cardiovascular diseases noninvasively. MATERIAL AND METHODS: 80 smoker and 50 non-smoker maintenance hemodialysis male patients with similar demographic characters, dialysis and support treatment and metabolic profile. In addition to routine tests, we took samples for evaluating IL-6, TNF-α, hsCRP and endothelin-1. P values were In smoker HD patients, IL-6, TNF-alpha, hsCRP and endothelin-1 levels were found increased level statistically significant compared to non-smoker indiviuals. CONCLUSION: This study may refer us that smoking is an additional risk factor among HD individuals by increased levels of IL-6, TNF-α, hsCRP and Et-1
INTRODUCCIÓN: Las enfermedades cardiovasculares (EC) constituyen una de las causas más frecuentes de mortalidad en los casos de enfermedad renal crónica. El tabaquismo es un factor de riesgo bien definido para la enfermedad cardiovascular aterosclerótica. Se encontraron valores elevados de Interleucina-6 (IL-6), factor de necrosis tumoral alfa (TNFα), proteína C-reactiva de alta sensibilidad (hs-CRP) y Endotelina-1 (Et-1) en el proceso inflamatorio crónico. OBJETIVO: El objetivo fue analizar si los valores de IL-6, TNFα, hs CRP y Et-1 son más elevados en los pacientes fumadores en hemodiálisis que en los no fumadores para predecir una posible enfermedad cardiovascular de forma no invasiva. MATERIAL Y MÉTODOS: Se incluyeron pacientes masculinos en hemodiálisis de mantenimiento, 80 fumadores y 50 no fumadores, similares en cuanto a sus características demográficas, tratamiento de diálisis y de mantenimiento, y perfil metabólico. Además de los análisis de rutina, se tomaron muestras para evaluar los valores de IL-6, TNFα, hs CRP y Endotelina-1. Se midieron los valores de p. RESULTADOS: Se halló una diferencia estadísticamente significativa en los niveles de IL-6, TNFα, hs CRP y Endotelina-1: fueron más elevados en los pacientes sometidos a hemodiálisis que eran fumadores en comparación con los no fumadores.CONCLUSIÓN: Este estudio podría demostrar que el tabaquismo es un factor de riesgo adicional para los pacientes que se tratan con hemodiálisis según muestran los valores elevados de IL-6, TNFα, hs CRP y Et-1
