Postpartum renal failure: a complex case with probable coexistence of hemolysis, elevated liver enzymes, low platelet count, and hemolytic uremic syndrome.

BACKGROUND

Postpartum renal failure in previously healthy subjects is associated most often with preeclampsia and/or hypertension; hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, hemolytic uremic syndrome; or thrombotic thrombocytopenic purpura. Transient oliguria associated with preeclampsia is common, but renal failure is rare. Coexistence of HELLP and hemolytic uremic syndromes has been suggested, but histopathologic documentation of this combination has been scarce.

CASE: A 30-year-old primigravida with severe preeclampsia at 35 weeks and 3 days' gestation presented with the development of HELLP syndrome and renal failure postpartum. Histopathologic lesions characteristic of hemolytic uremic syndrome were present in the kidney.

CONCLUSION

Probable overlapping of HELLP and hemolytic uremic syndromes in pregnancy or postpartum should be taken into consideration when treating patients with these syndromes and associated complications, such as renal failure.
