Relationship between structural damage with loss of strength and functional disability in psoriatic arthritis patients.

BACKGROUND: Evaluate the relationship between structural damage assessed by radiography or ultrasonography in the hands of patients with psoriatic arthritis (PsA) with loss of strength together with functional disability. METHODS: A cross-sectional study was conducted in patients with PsA involving the hands. Erosions and loss of radiographic joint space were measured in the dominant hand using a modified Sharp van der Heijde method and an ultrasound assessment. Hand strength was assessed with a dynamometer and disability was assessed using the Health Assessment Questionnaire (HAQ). The statistical analysis was performed using multiple linear regression models. FINDINGS: 76 patients were included with a mean age of 57 ±â€¯9.9 years, with 56.6% women. A statistically significant relationship was found between presence of erosions and reduction in lateral (p = 0.027) and tip (p = 0.030) pinch strength in the hand. This was also the case for loss of joint space and reduction in lateral (p = 0.012) and tip (p = 0.006) pinch strength. There was an association between total ultrasound (US) alterations and reduction in lateral pinch strength (p = 0.03). An association was also observed between erosions, loss of joint space and total US alterations and disability measured by the HAQ (p < 0.001; <0.001; 0.012, respectively). HAQ scores were associated with a decrease in mean lateral (p < 0.001) and tip (p < 0.001) pinch strength. INTERPRETATION: In patients with PsA involving the hands, structural alterations of the dominant hand assessed by conventional x-ray and ultrasound are associated with loss of strength measured objectively with dynamometry and greater disability also studied subjectively using the HAQ.

Afectación articular secundaria a infección por virus de Epstein-Barr / Joint involvement secondary to Epstein-Barr virus

Describimos un grupo de pacientes con infección por virus de Epstein-Barr (VEB) y manifestaciones articulares. Entre febrero del 2011 y enero del 2012 se ha recogido un total de 6 casos en nuestra sección. Dos de ellos se presentaron con un patrón similar a la artritis reumatoide, en forma de poliartritis simétrica de pequeñas y grandes articulaciones. Tres presentaron poliartralgias de ritmo inflamatorio y solamente una de las pacientes presentó una oligoartritis asimétrica de grandes articulaciones. Todas fueron mujeres con edades comprendidas entre los 25 y los 75 años (4 de ellas en edad fértil). En todas se realizó el diagnóstico de exclusión de otras posibles etiologías y se obtuvieron IgM negativas para el resto de virus de la familia Herpesviridae. En nuestra serie, la afección articular por VEB fue más frecuente en mujeres en edad fértil, con una presentación clínica heterogénea, predominando la forma de artralgias inflamatorias. La presentación en forma de poliartritis simétrica puede cronificarse y hacer necesario el uso de fármacos antirreumáticos modificadores de la enfermedad (AU)

We describe a group of patients with Epstein-Barr virus (EBV) infection and joint involvement. Between February 2011 and January 2012, there were six cases in our unit. Two presented with a pattern similar to rheumatoid arthritis, three had polyarthralgia with an inflammatory pattern and only one patient had asymmetrical oligoarthritis of large joints. They were all women aged between 25 and 75 (4 were of child-bearing potential). Diagnosis in all the cases was made by exclusion of other possible causes and negative IgM were obtained for the rest of the "Herpesviridae" family viruses. In our series, EBV joint involvement was more common in women of childbearing potential. Clinical presentation was heterogeneous but was predominantly in the form of inflammatory joint pain. When it presents in the form of symmetrical polyarthritis, it can become chronic and require the use of disease-modifying anti-rheumatic drugs (AU)
