Alexion starts eculizumab clinical trial in Shiga-toxin producing E.

EHEC infections have become uncommon, and the STEC-HUS complication of EHEC, which affects just a subset of the patients, is ultra-rare. STEC-HUS, a devastating and life-threatening disease, is normally due to uncontrolled complement activation. As announced on May 30, 2011, in response to requests of German physicians and hospitals who are treating individuals with STEC-HUS, Alexion offers initiated an eculizumab access plan and has been providing eculizumab free of charge throughout the crisis.Reuben describes malignancy stem cells as tumor cells found in the bone marrow that can handle self-renewal, thus a potential catalyst for recurrence and metastasis. Until now, the idea of malignancy stem cells and their level of resistance to chemotherapy provides been explained in the lab in animal models. With this study, we are characterizing cancers stem cells and determining them in breast cancer patients for the first time consistently, said Reuben, the study’s first writer. Our research showed a higher presence of cancer stem cells correlated with more advanced disease, suggesting that they may one day be a prognostic factor for determining those at best risk for metastasis and recurrence. Cancer stem cells certainly are a small but important component of circulating and disseminating tumor cells, both been shown to be independent prognostic elements for breast cancer already, in that they are self-renewing.
