Two Cases of Antituberculosis Drug-induced Hypersensitivity Syndrome / 대한피부과학회지

Drug-induced hypersensitivity syndrome is a rare, but severe, life-threatening disease with multiorgan failure. Aromatic antiepileptic drugs are frequent causes of this syndrome. The association of the human herpes virus-6 has been recently reported in patients with drug-induced hypersensitivity syndrome. We report two patients who were diagnosed as having antituberculosis drug-induced hypersensitivity syndrome based on clinical course and laboratory data. In addition, human herpes virus-6 DNA was detected by polymerase chain reaction in peripheral blood mononuclear cells and the serum. There was a favorable outcome after discontinuation of the causative drug, plus corticosteroid therapy. After the treatment, human herpes virus-6 DNA was not detected by polymerase chain reaction. This is the first report of antituberculosis drug-induced hypersensitivity syndrome associated with reactivation of human herpes virus-6.

Pulmonary Cryptococcosis after Chemotherapy in a Patient with Non-Hodgkins Lymphoma / 감염과화학요법

Non-Hodgkin's lymphoma is monoclonal expansion of malignant B or T cells. The immunocompromised status in this disease is accompanied by many infections. The cryptococcosis, caused by Cryptococcus neoformans, frequently occurs in leukemia, Hodgkin's disease, sarcoidosis, diabetes mellitus, tuberculosis, and long-term steroid-using patients. Recent increasing incidence of fungal infection could be due to the spread of AIDS and transplantation. We experienced one patient with lung mass in Non-Hodgkin's lymphoma after three cycles of chemotherapy, which could not be discriminated from the newly developed lymphoma mass. Cryptococcus neoformans was isolated from the lung tissue obtained by thoracoscopic biopsy. Herein we report this case with brief review of pertinent literature.

A Case of Tricuspid Valve Endocarditis with Vegetation in a Non-Drug Addict without Underlying Cardiac Disease

Tricuspid valve endocarditis accounts for 5% to 10% of cases of infective endocarditis. It commonly occurs in intravenous drug abusers, intravenous catheters, alcoholism, immune deficiency and genital sepsis. But right sided infective endocarditis without predisposing factor is very rare. S. aureus is the usual pathogen. We experienced a case of tricuspid valve endocarditis in a 32 year old female with vegetation in a non drug addict without underlying cardiac disease. The vegetation on the septal cusp of tricuspid valve and tricuspid regurgitation were found by TTE & TEE. S. aureus was identified in 4 bottles of blood cultures. The diagnosis was delayed because the cardiac manifestations of the disease were subtle, and pleuropulmonary manifestations predominant. So we report a case of tricuspid valve endocarditis in a non drug addict without underlying cardiac disease with a review of literature.
