Polyclonal anti-thymocyte globulin (ATG) is used as an immunosuppressive agent in the treatment of aplastic anemia (AA). Serum sickness is a recognized side effect of ATG. We observed abnormal skin manifestation in patient with aplastic anemia who had been treated with ATG. We conclude that abnormal immune function caused by aplastic anemia and ATG and corticosteroids may aggravate the signs of...

Ipilimumab is a human monoclonal IgG1 antibody against CTLA-4 that has been shown to prolong the overall survival of advanced melanoma. The most common adverse events associated with ipilimumab are immune-related. Severe hematological toxicity is rare. We report a case of severe neutropenia following ipilimumab therapy that fully resolved after the administration of prednisone, cyclosporine, an...

BACKGROUND Thymoglobulin® (anti-thymocyte globulin [rabbit]) is a purified pasteurised, gamma immune globulin obtained by immunisation of rabbits with human thymocytes. Anaphylactic allergic reactions to a first injection of thymoglobulin are rare. CASE PRESENTATION We report a case of serious anaphylactic reaction occurring after a first intraoperative injection of thymoglobulin during renal...

Therapy with anti-lymphocyte and anti-thymocyte globulins, two animal-derived preparations used as immunosuppressive agents, results in high concentrations of foreign immunoglobulin circulating in plasma. We describe a case that illustrates how the presence of these immunoglobulins can interfere with double-antibody radioimmunoassay procedures.
