Oxaliplatin is a platinum compound used in patients with gastrointestinal malignancies. It is known to evoke a drug-induced immune-mediated thrombocytopenia, which has not been reported in Korea. We describe a 53-year-old man who developed oxaliplatin-induced immune-mediated thrombocytopenia during chemotherapy for colon cancer. Oxaliplatin-dependent IgG platelet antibodies were detected in his...

A patient was diagnosed with autoimmune thrombocytopenia and concurrent diffuse large B-cell lymphoma (DLBCL). Both autoimmune thrombocytopenia and DLBCL were successfully treated using chemotherapy, while steroid therapy, rituximab monotherapy, and high-dose parenteral glucocorticoid therapy combined with high-dose intravenous immunoglobulin failed to improve thrombocytopenia. A greater unders...

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a condition characterized by thrombocytopenia in the newborn. If severe, the thrombocytopenia can lead to intracranial hemorrhage. FNAIT arises when maternal antibodies specific for platelet antigens, most commonly β3 integrin, cross the placenta and destroy fetal platelets. Surprisingly, few cases of FNAIT are associated with antibodies...

Prolonged thrombocytopenia in a usual case of dengue virus infection is uncommon. Dengue-related thrombocytopenia is self-limiting and responds within 3-5 days. An underlying immunological disorder may be responsible for delayed return of platelet count to a normal level. We present a case of prolonged thrombocytopenia in a case of dengue hemorrhagic fever. The response to steroids suggests a p...

Heparin is a drug widely used for thromboprophylaxis or treatment in many clinical situations. However, it can cause serious adverse effects, including thrombocytopenia, which is a potentially life-threatening condition. Unfortunately, heparin-induced thrombocytopenia is generally under-recognised and under-diagnosed. A case of heparin-induced thrombocytopenia occurring in a post-operative orth...

Rifampicin occasionally causes thrombocytopenia when given as part of an intermittent regimen. A case is reported of severe thrombocytopenia developing after one dose of rifampicin, following a 4-month gap in daily therapy. The literature on rifampicin-induced thrombocytopenia is reviewed.

Ganciclovir is a nucleoside guanosine analogue that exhibits therapeutic activity against human cytomegalovirus infection, and is primarily excreted via glomerular filtration and active tubular secretion. The adverse effects induced by ganciclovir therapy are generally of a hematological nature and include thrombocytopenia and leukopenia. Low marrow cellularity and elevated serum creatinine hav...

While mild thrombocytopenia in systemic lupus erythematosus (SLE) is frequently seen in the context of active disease, severe thrombocytopenia causing significant bleeding is not that common. Corticosteroids are considered the first line therapy for severe thrombocytopenia in SLE. Second-line therapeutic agents or splenectomy have been reported to be effective for patients who fail to respond t...

BACKGROUND Congenital hemangiomas are benign abnormal proliferation of blood vessels. Noninvoluting congenital hemangiomas are a rare variant which persist, and may become bigger. Hemangiomas are known to be associated with thrombocytopenia, microangiopathic hemolytic anemia and Kasabach-Merritt phenomenon. Kasabach-Merritt phenomenon is characterized by consumptive coagulopathy with microangio...

Background: Osteopetrosisis an inherited and rare bone disease, characterized by the impairment ofbone modeling and remodeling and the failure of osteoclasts to resorb bone. It also results in skeletal fragility despite increased bone mass, and may cause hematopoietic insufficiency, disturbed tooth eruption, nerve entrapment syndromes, and growth impairment. The infantile form of the disease is...
