Purpose: Cystic echinococcosis (CE) is a neglected tropical disease prevalent worldwide, particularly in rural areas. Previous studies evaluated immune responses in patients with hepatic CE, however none had assessed Th1, Th2 and Th17 levels simultaneously in pulmonary CE patients. This study aimed to fill this gap in literature by using flow cytometry analysis.

Increasing world population parallelly also brings an increase in food production and consumption. As food consumption increases, so do foodborne infections. In cases where adequate food safety and hygiene is not provided in places such as restaurants, dormitories, prisons, hospitals where mass feeding is made outside the home, many parasitic agents can be transmitted to people through food.

Objective: The aim of this study was to determine the levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), and malondialdehyde (MDA) in the patients infected with and establish whether these parameters differ among the patients with fascioliasis.

Methods: The patient group consisted of 140 individuals with seropositive; the control group consisted of 140 healthy individuals who tested negative for this parasite and had no other diseases. The patient group consisted of individuals with no chronic diseases other than fascioliasis; in both the patient and the control groups, the subjects had no unhealthy habits such as smoking and alcohol consumption, etc.

Background: Cytokines are protein substances involved in immune response and inflammation regulation, cell growth, tissue repair and natural and adaptive immunity events such as hematopoiesis. Changes in Th1 and Th2 immune responses provide information on the clinical presentation, pathology and diagnosis of diseases.

Methods: This study was conducted on 142 patients, aged 18-95 yr and applied to Parasitology Laboratory of Van Yuzuncu Yil Hospital between Aug 2018 and May 2019.
