title: Study of the liver changes occurring in preeclampsia and their possible pathogenetic connection with acute fatty liver of pregnancy.
abstract: OBJECTIVE
  The objective of the present study was to investigate liver involvement in preeclampsia on the basis of clinical, laboratory, and histological data and to detect a possible connection with fatty liver of pregnancy by the determination of microvesicular fatty infiltration of the liver.
  
  
  METHODS
  The authors studied the liver changes in 10 patients with preeclampsia, observing the clinical and laboratory alterations, the macroscopic liver surface features by laparoscopy, and the presence of microvesicular fatty infiltration by specific lipid staining of hepatic tissue collected by needle biopsy.
  
  
  RESULTS
  Macroscopy of the liver surface disclosed some degree of subcapsular liver hemorrhage in all cases; however, the hemorrhage was not related to the clinical and histological severity of the disease. Microvesicular fat droplets were observed in all patients, and the intensity of the fat deposition was not related to pressor levels, laboratory alterations, or the evolution of preeclampsia.
  
  
  CONCLUSIONS
  The presence of fatty liver infiltration in all patients studied supports the idea that preeclampsia and acute fatty liver of pregnancy could be components of the same pathologic spectrum, with a probable, but still unproved, pathogenetic connection. The deficiency of the long chain 3-hydroxyacyl-coenzyme A dehydrogenase activity may be the determining factor in the evolution of the disease.
