A case of common variable immunodeficiency syndrome associated with Takayasu arteritis.

BACKGROUND

Association of common variable immunodeficiency (CVID) with Takayasu arteritis has rarely been reported.

OBJECTIVE

To describe a case of Takayasu arteritis in a 53-year-old Hispanic woman with CVID undergoing long-term (3-year) intravenous immunoglobulin (IVIG) treatment.

METHODS

The patient's serum immunoglobulin levels and antibody titers to measles, mumps, and rubella were measured. She also underwent angiography of the large vessels.

RESULTS

Low to undetectable serum IgA, IgM, and IgG levels and low antibody titers to mumps, measles, and rubella were consistent with the diagnosis of CVID. The angiogram showed narrowing of the proximal left subclavian artery (2-3 mm in diameter).

CONCLUSIONS

This patient developed Takayasu arteritis while receiving IVIG for CVID. She clinically improved after her IVIG dose was increased. To our knowledge, this is the second reported case of Takayasu arteritis associated with CVID.
