Markers for preeclampsia
View Patent ↗This document provides methods and materials related to determining whether or not a pregnant mammal (e.g., a pregnant human) has preeclampsia. For example, methods and materials related to the use of urinary podocytes to determine whether or not a pregnant human has preeclampsia are provided.
1. A method for avoiding unnecessary treatment of preeclampsia, said method comprising:
(a) contacting a urine sample collected from a pregnant human during gestational week 18 to 36 with an antibody under conditions that allow binding of said antibody to a podocyte or a fragment of said podocyte, wherein, when said urine sample contains podocytes or fragments of said podocytes, antibody complexes comprising said antibody and said podocyte or a fragment of said podocyte are formed,
(b) detecting an absence of an elevated level of said antibody complexes as compared to corresponding urine levels from pregnant humans lacking preeclampsia, and
(c) proceeding with treatment of said pregnant human in a manner that avoids unnecessary treatment of preeclampsia based on the urine levels of said antibody complexes detected in step (a) in said pregnant human.
2. The method of claim 1 , wherein said antibody is an anti-podocin antibody.
3. The method of claim 1 , wherein said antibody is an anti-podocalyxin antibody.
4. The method of claim 1 , wherein said antibody is an anti-nephrin antibody.
5. The method of claim 1 , wherein said antibody is an anti-synaptopodin antibody.
