Evaluation of pre- and post-surgical oxidative stress parameters in patients with pulmonary cystic echinococcus.
BACKGROUND
Hydatid cyst secretes numerous immunomodulatory molecules to the host, and the host reacts these molecules by activating immune response. It is also known that, immune cells generally produce more oxidative products.


OBJECTIVE
In this study, we aimed to evaluate the antioxidant enzyme using catalase (CAT) and oxidant enzyme using lipid hydroperoxide (LOOH) levels in the serum samples before and after the surgical interventions in patients with pulmonary cystic echinococcus (CE).


METHODS
Forty patients with pulmonary CE who underwent surgery and 40 healthy individuals were enrolled to the study. Patients were divided in two groups; group 1 (n=40) consisted of patients with pulmonary CE, and group 2 (n=40) consisted of healthy subjects. Before and after surgical interventions serum CAT and LOOH levels were measured.


RESULTS
Compared to group 2, group 1 had significantly lower CAT and higher LOOH levels before surgery (both p < 0.001). In group 1; CAT levels were significantly increased and LOOH levels significantly increased after the surgical intervention (both p < 0.001).


CONCLUSIONS
The present study showed that oxidative stress increased in patients with pulmonary CE, may be consequence of immune response of the host, and these levels decreased after the surgical intervention.
