ABSTRACT
Presentamos las características clínicas y serológicas de cuatro pacientes con diagnóstico de rhupus (definición de Simon). Presentaban criterios ACR tanto para LES como para AR, factor antinuclear (FAN) positivo a títulos desde 1/80 a 1/5.250 y anti-DNAn positivo, predominando como manifestación clínica una poliartritis simétrica erosiva. Se halló anti-CCP positiva y a títulos altos en 3 de los 4 pacientes y anticuerpos antifosfolípidos en 2 (anticardiolipina y anticoagulante lúpico), sin manifestación de síndrome antifosfolípido. Sólo un paciente presentó compromiso renal y 2 nódulos subcutáneos. En 3 de los pacientes el diagnóstico de AR precedió a las manifestaciones de LES en un promedio de 7,7 años. La mitad fue refractaria a fármacos antirreumáticos modificadores de la enfermedad (FAME) convencionales en combinación y requirió biológicos y micofenolato mofetil (AU)
We present the clinical and serological characteristics of four patients with rhupus (Simons definition). The 4 patients with rhupus presented ACR criteria for SLE as well as for RA, ANA positive with titers ranging from 1/80 to 1/5,250, and positive anti-DNA, with the predominance of symmetrical erosive polyarthritis. We found anti-CCP positivity and high titers in 3 of the 4 patients, and positive antiphospholipid antibodies in 2 (anticardiolipin and LA), without manifestation of antiphospholipid syndrome. One patient presented renal affection, and 2 subcutaneous nodules. The 3 patients with RA preceded the manifestations of SLE by an average of 7.7 years. Two patients were refractory to conventional DMAR in combination, requiring biologic and mycophennolate mofetil (AU)
