Hypertension, inflammation and T lymphocytes are increased in a rat model of HELLP syndrome.


ABSTRACT: An animal model of hemolysis, elevated liver enzymes, low platelet count (HELLP) was used to determine if T lymphocytes accompany hypertension and increased inflammatory cytokines.sFlt-1 (4.7?µg/kg/day) and sEndoglin (7?µg/kg/day) were infused into normal pregnant rats (HELLP rats) for 8 days.HELLP was associated with increased mean arterial pressure (p?=?0.0001), hemolysis (p?=?0.044), elevated liver enzymes (p?=?0.027), and reduced platelets (p?=?0.035). HELLP rats had increased plasma levels of TNF? (p?=?0.039), IL-6 (p?=?0.038) and IL-17 (p?=?0.04). CD4(+) and CD8(+) T lymphocytes were increased.These data support the hypothesis that T cells are associated with hypertension and inflammation.

<h4>Objective</h4>An animal model of hemolysis, elevated liver enzymes, low platelet count (HELLP) was used to determine if T lymphocytes accompany hypertension and increased inflammatory cytokines.<h4>Methods</h4>sFlt-1 (4.7 µg/kg/day) and sEndoglin (7 µg/kg/day) were infused into normal pregnant rats (HELLP rats) for 8 days.<h4>Results</h4>HELLP was associated with increased mean arterial pressure (p = 0.0001), hemolysis (p = 0.044), elevated liver enzymes (p = 0.027), and reduced platelets (p  ...[more]
