Sunitinib is an orally administered inhibitor of tyrosine kinases and has become the standard of care for many patients with metastatic renal cell carcinoma. Its use has been associated with renal toxicity in some patients. We report a patient with a metastatic clear-cell renal carcinoma who showed
Pulmonary hypertension (PH) induced by pulmonary tumor thrombotic microangiopathy (PTTM) can be fatal because its rapid progression confounds diagnosis, and it is difficult to control with therapy. Here we describe a woman with symptomatic PTTM-PH accompanying gastric cancer that was suspected from
The third-generation tyrosine kinase inhibitor (TKI) ponatinib has been associated with high rates of acute ischemic events. The pathophysiology responsible for these events is unknown. We hypothesized that ponatinib produces an endothelial angiopathy involving excessive endothelial-associated von
Agents that block vascular endothelial growth factor (VEGF) and its downstream pathway have been reported to be associated with nephrotoxicity including hypertension, proteinuria, and renal dysfunction. Bevacizumab, a monoclonal antibody against VEGF, is known to cause thrombotic microangiopathy
BACKGROUND
Pulmonary tumor thrombotic microangiopathy (PTTM) is rare, cancer-related pulmonary complication leading to hypoxia, pulmonary hypertension, and heart failure. The standard treatment for PTTM is not established. However, imatinib, a tyrosine kinase inhibitor of the PDGF receptor, may
Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare malignancy-related respiratory complication, showing rapid progression of respiratory dysfunction and pulmonary hypertension (PH). Accumulating evidence suggests that imatinib, a platelet-derived growth factor (PDGF) receptor-tyrosine
Hematological malignancies, including chronic myeloid leukemia (CML), exhibit ASXL1 mutations; however, the function and molecular mechanism of these mutations remain unclear. ASXL1 was originally identified as tumor suppressor gene, in which loss of function causes myelodysplastic
Drug-mediated thrombotic microangiopathy may cause life-threatening medical emergencies. Novel targeted therapies have dramatically changed the prognosis of a number of oncological diseases. Tyrosine kinase inhibitors of the Breakpoint Cluster Region-Abelson (BCR-ABL) oncoprotein are used in
Thrombotic microangiopathy (TMA) is a life-threatening condition that affects some, but not all, recipients of vascular endothelial growth factor (VEGF) inhibitors given as part of chemotherapy. TMA is also a complication of preeclampsia, a disease characterized by excess production of the
Sunitinib is an oral, multitargeted receptor tyrosine kinase inhibitor of targets such as vascular endothelial growth factor and platelet derived growth factor receptor. It is used for the treatment of metastatic renal cell carcinoma (RCC). Use of sunitinib has been associated with renal dysfunction
BACKGROUND
Focusing on glomerular thrombotic microangiopathy (TMA), we detected urinary podocytes to evaluate podocyte damage following glomerular endothelial cell injury.
METHODS
We analyzed the relationship between urinary podocytes as biomarkers for podocyte injuries and clinical manifestations
Small molecule tyrosine kinase inhibitors (TKIs) are potent anti-cancer targeted therapies. TKIs are considered safe and efficacious therapeutic modalities, and are generally tolerated well. However, they are associated with certain side effects including hematologic toxicities such as anemia,
BACKGROUND
Tyrosine kinase (TK) inhibitors are increasingly being used to treat a variety of pediatric malignancies. Reports in adult patients describe a range of effects of TK inhibitors on the kidney, including hypertension, proteinuria, acute kidney injury, and thrombotic microangiopathy (TMA);
Thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) are clinically similar disorders characterized by microvascular thrombosis, hemolysis, thrombocytopenia, and end-organ damage. Although they may present with overlapping symptoms, multiple etiologies have been proposed for
BACKGROUND
Drugs targeting the VEGF pathway are associated with renal adverse events, including proteinuria, hypertension and thrombotic microangiopathy (TMA). Most cases of TMA are reported secondary to bevacizumab. It was shown recently that sunitinib, a small molecule inhibiting several tyrosine
