Pneumococcal pericarditis with cardiac tamponade in a patient with chronic graft-versus-host disease

Abstract

We report a case of pneumococcal pericarditis in a 13-year-old boy following allogeneic BMT from an HLA-identical unrelated donor. The post-transplant course was complicated by chronic GVHD which led to reinstitution of immunosuppressive therapy. Eight months after BMT the patient developed pericarditis with cardiac tamponade, and Streptococcus pneumoniae was isolated in the pericardiocentesis fluid. This is the first reported case of pneumococcal pericarditis after BMT. Although pericardial effusions after allogeneic BMT are often sterile and related to conditioning therapy or associated with chronic GVHD, rapid microbiological investigation and empirical treatment with antibiotics are necessary. Prophylaxis for pneumococcal infection in patients with chronic GVHD is recommended.
