Acute Arterial Ischemia in a Patient With Polyarthritis

Summary: | Cryoglobulins are immunoglobulins that precipitate at cold temperatures. Their presence can be related to a type of vasculitis referred to as cryoglobulinemia. This condition, especially mixed cryoglobulinemia, has been associated with viral infections like hepatitis C virus in 60%–90% of cases, but it has also been reported in relation to connective tissue diseases, usually resulting in a more severe course. We describe the case of a patient with seronegative polyarthritis who developed acute arterial ischemia in association with cryoglobulinemia, with a good response to rituximab therapy.
Las crioglobulinas son inmunoglobulinas que precipitan con el frío. Su presencia puede asociarse a un tipo de vasculitis denominada crioglobulinemia. Estas, especialmente las mixtas, se asocian a infecciones como el virus de la hepatitis C hasta en el 60–90% de los casos, aunque también se ha descrito su asociación a enfermedades del tejido conectivo, en las que suele tener un curso más agresivo. Se presenta el caso de una paciente con poliartritis seronegativa que desarrolló isquemia arterial aguda en el contexto de una crioglobulinemia y que ha respondido al tratamiento con rituximab. |
