Response to minocycline of arthritis associated with agammaglobulinemia. A case-report.

Seven to 22% of patients with agammaglobulinemia develop joint manifestations consisting of septic arthritis or aseptic arthritis of unclear pathogenesis. Intravenous gammaglobulin therapy seems effective on the latter condition but is burdensome and expensive. We report the case of a patient with common variable immunodeficiency and aseptic oligoarthritis in which minocycline therapy was effective in relieving the joint symptoms.
