The differential should include other causes of hemolysis, such as that found in non-immune hemolytic anemia including intrinsic red cell defects, hemolysis due to extrinsic factors (ie trugs or toxins) as well as mechanical damage hemolytic anemia as found in DIC and HUS.
There are typically three classes, or groups, or antibiotics healthcare providers will use when treating bacterial pneumonia: 1  Beta-lactams: Recommended drugs in this class include high-dose amoxicillin (Amoxil), amoxicillin-clavulanate (Augmentin), cefpodoxime (Vantin), and cefuroxime (Ceftin).
