Resumen

:Los anticuerpos antinucleares (AAN) son considerados como marcadores de enfermedad autoinmune. Se conocen distintas reactividades específicas de los AAN, entre las que se encuentra el complejo Ro (SS-A). Aunque la presencia de anticuerpos anti-Ro es ampliamente conocida en conectivopatías sistémicas, como el lupus eritematoso o el síndrome de Sjögren, hay pocos estudios que intenten relacionar esta partícula con la hepatitis autoinmune (HAI). Presentamos un caso de HAI de curso agudo, en una mujer de 55 años, con anti-Ro positivo de 60 kD. El antígeno Ro (SS-A) es una ribonucleoproteína compleja, cuya estructura está sometida a debate y de la que se conocen dos fracciones fundamentales de 52 y 60 kD, respectivamente. En la revisión efectuada se encuentran unas frecuencias entre las HAI del 21 al 34% para anti-Ro de 52 kD, y del 9 al 13,6% para anti-Ro de 60 kD. A pesar de no haberse demostrado ninguna relación de este complejo con mecanismos etiopatogénicos o con patrones clínicos de las HAI, se proponen investigaciones multicéntricas con series amplias antes de descartar definitivamente la implicación de los anticuerpos anti-Ro en estas enfermedades.

Antinuclear antibodies (ANA) are considered to be markers of autoimmune disease. Several specific reactivities of ANA are known, among them the Ro (SS-a) complex. Although the presence of anti-Ro antibodies is widely known in systemic connective tissue diseases such as lupus erythematous or Sjögren's syndrome, few studies have attempted to link this finding with autoimmune hepatitis (AIH). We present a case of acute AIH in a 55-year-old woman who tested positive for anti-Ro 60 kD antibodies. The Ro (SS-A) antigen is a complex ribonucleoprotein whose structure is still the subject of debate. Two fractions, of 50 and 60 kD, have been identified. A review of the literature revealed frequencies of 21-34% for anti-Ro 52 kD and of 9-13-6% for anti-Ro 60 kD in AIH. Although no relationship has been demonstrated between this complex and the etiopathogenic mechanisms or clinical patterns of AIH, we propose that multicenter investigations with large series should be performed before the possible involvement of anti-Ro antibodies in these diseases is definitively ruled out.
