Abstract
In some embodiments, the present invention provides methods for treating pregnant patients at risk of adverse pregnancy outcome, including, in some embodiments, by measuring one or more of a level of iC3b, intact C3, and total C3.
Claims12
A method for treating a pregnant human at risk of an adverse pregnancy outcome comprising:
- (i) detecting in a first sample of blood or urine from the pregnant human a first level of iC3b, intact C3, and/or total C3 at a first time point during the first, second, or third trimester of pregnancy;
- (ii) detecting in a second sample of blood or urine from the pregnant human a second level of iC3b, intact C3, and/or total C3 at a second time point during the third trimester of pregnancy;
- (iii) comparing the first and second levels;
- (iv) diagnosing the pregnant human as being at risk of an adverse pregnancy outcome by determining that the first and second levels are:
- (a) iC3b and the second level is higher than the first level;
- and/or
- (b) iC3b and intact C3 and the ratio of intact C3 to iC3b is the same as or lower than the first level;
- and/or
- (c) total C3 and the second level is the same as or lower than the first level;
- and
- (v) treating the pregnant human diagnosed as being at risk of an adverse pregnancy outcome with a treatment comprising administration of one or more of steroids, non-steroidal anti-inflammatory drugs (NSAIDs), hydroxychloroquine, chloroquine, quinacrine, methotrexate, azathioprine, cyclophosphamide, chlorambucil, cyclosporine, mycophenolate mofetil, rituximab, belimumab, complement inhibitors, plasmapheresis, delivery of the fetus, aspirin, one or more agents for treatment of hypertension, and/or one or more agents for treatment of eclamptic seizures.

- (i) detecting in a sample of blood or urine from the pregnant human a level of iC3b, total C3, and/or iC3b and intact C3, during the first, second, or third trimester of pregnancy;
- (ii) comparing the level of total C3, iC3b, and/or iC3b and intact C3 from the pregnant human to one or more reference levels;
- (iii) diagnosing the pregnant human as being at risk of an adverse pregnancy outcome by determining that the level from the pregnant human is outside of a range of normal levels;
- and
- (iv) treating the pregnant human diagnosed as being at risk of an adverse pregnancy outcome with a treatment comprising-administration of one or more of steroids, non-steroidal anti-inflammatory drugs (NSAIDs), hydroxychloroquine, chloroquine, quinacrine, methotrexate, azathioprine, cyclophosphamide, chlorambucil, cyclosporine, mycophenolate mofetil, rituximab, belimumab, complement inhibitors, plasmapheresis, delivery of the fetus, aspirin, one or more agents for treatment of hypertension, and/or one or more agents for treatment of eclamptic seizures.
