Retrospective Analysis of Cystic Echinococcosis Results in Aydın Adnan Menderes University Training and Research Hospital Parasitology Laboratory Between 2005 and 2017

Objective
Echinococcus granulosus is the causative helminth of cystic echinococcosis (CE). The parasite is known to form fluid-filled cysts that grow slowly in the internal organs, particularly the liver and/or lungs. This disease is still important in terms of public health and economically in Turkey and other countries where animal husbandry is widespread. The aim of our study was to retrospectively evaluate the cases that were admitted to the Adnan Menderes University, Training and Research Hospital Parasitology laboratory on suspicion of CE between January 2005 and January 2017.


Methods
Totally, 3446 sera (from 2019 female and 1427 male) were tested with an in-house ELISA for the presence of E. granulosus specific IgG antibodies at the timeswhen they were sent. Socio-demographic characteristics (age, gender, residence, and dog ownership), positivity titers, and cyst locations of pathologically confirmed CE patients were analyzed retrospectively.


Results
The ages of patients varied between 4-87 years. It was found that 1104 (32%) of the 3446 sera were positive, and of them, 642 (58.1%) were female and 462 (41.9%) were male. Patients who had pathologically confirmed CE diagnosis constituted 247 (22.3%) of the total seropositive sera. Liver was the most commonly affected organ (81.8%), followed by lungs (6.1%).


Conclusion
CE remains an important public health problem in our city; therefore, it is once again emphasized that preventive studies should be planned.
