Objective: To test the hypothesis that a quantitative defect of maternal cellular mitochondria would play a role in the pathogenesis of HELLP syndrome. Study design: Peripheral blood mitochondrial DNA (MtDNA) was measured in 20 non-pregnant women with a history of HELLP syndrome, 40 non-pregnant control subjects who had previous physiologic pregnancies, 59 subjects carrying physiologic pregnancies, seven pregnant women with a history of HELLP syndrome and five women in the active phase of the disease. Main outcome measure: Peripheral blood Mt-DNA. Results: The median (interquartile range) mtDNA in women with a history of HELLP syndrome, in non-pregnant women who had previous physiologic pregnancies, in subjects carrying physiologic pregnancies, in pregnant women with a history of HELLP syndrome and in women in the active phase of the disease was 115 (81-194), 229 (199-319), 174 (136-211), 101 (82-178) and 92 (39-129) copies per nuclear DNA, respectively. Non-pregnant women with a history of HELLP syndrome had significantly lower levels than non-pregnant controls (p < 0.001). Moreover, blood mtDNA was lower in pregnant women with a history of HELLP syndrome and in those in the active phase of the disease when compared to pregnant controls (p = 0.002 and p = 0.025, respectively). Conclusions: Attenuated maternal mitochondrial function may favor HELLP syndrome development.

Main outcome measure: Peripheral blood Mt-DNA. Results: The median (interquartile range) mtDNA in women with a history of HELLP syndrome, in non-pregnant women who had previous physiologic pregnancies, in subjects carrying physiologic pregnancies, in pregnant women with a history of HELLP syndrome and in women in the active phase of the disease was 115 (81-194), 229 (199-319), 174 (136-211), 101 (82-178) and 92 (39-129) copies per nuclear DNA, respectively. Non-pregnant women with a history of HELLP syndrome had significantly lower levels than non-pregnant controls (p < 0.001).
