The present invention relates generally to the field of disorders of complement activation. More specifically, the present invention provides methods and compositions useful for diagnosing and treating atypical hemolytic uremic syndrome, antiphospholipid antibody syndrome and other disorders of the alternative pathway of complement activation. In one embodiment, a method comprises the steps of (a) incubating or contacting serum obtained from a patient suspected of having atypical hemolytic uremic syndrome (aHUS) with a glycosylphosphatidylinositol-anchored protein (GPI-AP) deficient cell line; and (b) performing a cell viability assay on the cells from step (a). In a specific embodiment, the method further comprises the step of diagnosing the patient as having aHUS based on a statistically significant increased difference of non-viable cells from the patient serum as compared to a control.

Assay to diagnose and treat disorders of the alternative pathway of complement activation

The present invention relates to methods of treating a cancer and in particular, a B-cell derived cancer, using a lymphocytotoxic but hematopoeitic cell sparing high-dose pulsed amount of an oxazaphosphorine drug, either alone, or in combination with immune therapeutics such as, for example, monoclonal antibodies that selectively bind B-cell specific antigens.

Cyclophosphamide in combination with immune therapeutics

The present invention provides methods of identifying subjects that are suitable and not suitable for high-dose cyclophosphamide treatment.

Method of identifying patients not suitable for high-dose cyclophosphamide treatment

The present invention relates to methods of treating a cancer and in particular, a B-cell derived cancer, using a lymphocytotoxic but hematopoeitic cell sparing high-dose pulsed amount of an oxazaphosphorine drug in combination with immune therapeutics such as, for example, an autologous idiotypic vaccine and monoclonal antibodies that selectively bind B-cell specific antigens.

Cyclophosphamide in combination with anti-idiotypic vaccines

The present invention relates to toxins that specifically bind to GPI anchored proteins. More specifically, the present invention encompasses the uses of such toxins to detect the presence or absence of GPI anchored proteins. In one embodiment the present invention can be used to detect the presence of paroxysmal nocturnal hemoglobinuria.
