- W2945175597 abstract "DFS70 ANAs have attracted interest due to their frequency in individuals with no clinical evidence of systemic autoimmune rheumatic disease (SARD), groups with genetic risk for rheumatoid arthritis (RA) were not assessed. To determine the frequency of ANA and DFS70 ANA in blood relatives (BR) of people with RA compared to patients with early RA (ERA), and control individuals, and its association with health status. A cross-sectional study with an analytical component. Sixty ERA patients, 60 BR and 120 control individuals paired by age and sex were studied. Hep2-ANA and DFS70 ANA were studied. The absolute and relative frequencies and associations were established using logistic regression models, with a significance level of 95% 43% ANA in ERA, 30% in BR, and 25%-8% in control individuals 1:80. The fine dense granular pattern based on conventional Hep2 was found in 12%-9% of the positive samples, and 1.66% of the total samples. There was no detection of DFS70 ANAs in patients with ERA. In ERA there was an association between the presence of ANA and inflamed joints (P = .02), CRP (P = .01), DAS28CRP (P = .03) and HAQ (P = .04). There was an association between ANA and elevated CRP (P = .05) in the BR. In the control individuals, there was an association between ANA and painful joints (P = .02). In DFS70 ANA individuals we observed an association between a normal ESR P = .032, BR (-), P = .044 and absence of painful joints, p = .039 The frequency of DFS70 ANA in the groups studied was low, none of the patients with ERA was positive. The presence of DFS70 ANA was only confirmed in systemically healthy individuals. Los ANA/DFS70 han atraído el interés por su frecuencia en individuos sin evidencia clínica de enfermedad reumática sistémica autoinmune (ERAS), no se han evaluado grupos de riesgo genético para artritis reumatoide (AR). Determinar la frecuencia de ANA y ANA/DFS70 en familiares consanguíneos (FC) de AR comparada con pacientes con AR temprana (ARt) e individuos control y su asociación con el estado de salud. Estudio de corte transversal con componente analítico. Análisis de 60 pacientes ARt, 60 FC y 120 individuos control pareados por edad y sexo. Se analizaron ANA-HEp2 y ANA/DFS70. Establecieron las frecuencias absolutas y relativas y asociaciones con modelos de regresión logística, con un nivel de significancia del 95%. ANA de 43% en ARt, 30% en FC y 25,8% en individuos control a título 1:80. El patrón granular fino denso por Hep2 convencional se encontró en el 12,9% de las muestras positivas y el 1,66% del total de muestras. En ANA/DFS70 (+) en 1,66% en FC y 2,5% de individuos control, representando el 75% de la muestras positivas y el 1,25% del total de las muestras. No hubo detección de ANAS-DFS70 en pacientes con ARt. En ARt hubo asociación entre la presencia de ANA y articulaciones inflamadas (p = 0,02), PCR (p = 0,01), DAS28PCR (p = 0,03) y HAQ (p = 0,04). Asociación entre ANA y PCR elevada (p = 0,05) en FC. En individuos control entre ANA y articulaciones dolorosas (p = 0,02). En individuos ANA-DFS70 observamos asociación con VSG normal p = 0,032, FR(-), p = 0,044 y ausencia de articulaciones dolorosas, p = 0,039 La frecuencia de ANA/DFS70 en los grupos estudiados fue baja, ninguno de los pacientes con ARt fue positivo. Se confirma la presencia de ANA/DFS70 solo en individuos sanos sistémicamente." @default.
