Epidemiological and Clinical Characteristics of Patients with Hydatid Cysts in Khorasan Razavi Province, from 2011 to 2014


Background: This study aimed to investigate the epidemiological and clinical aspects of patients with hydatid cyst during 2011 to 2014.

Methods: This cross-sectional study was conducted in Khorasan Razavi Province, the Northeast of Iran, from 2011 to 2014. The study population was all cases with hydatid cyst who diagnosed in governmental and private laboratories, hospitals and health centers (HC) in Khorasan Razavi Province during 2011-14.

Results: The prevalence rate of hydatidosis was 1.44 per 100000 individuals. Of 357 cases, 54.9% were women, 40.3% rural, 45.8% housewives, and 3.4% were Afghan. The mean age of women was higher than that of men (39.13±18.9 compared to 34.7±17.9 yr, respectively, P-value=0.025). The highest proportion of cases (39.2%) was in the age group of 21-40 yr old. Abdominal pain was reported in 42.3% of cases. Liver involvement was the most common localization of hydatid cyst reported in 59.4% of patients, and 8.4% had multiple organ involvement. The common diagnosis methods of the disease were radiology (42.3%) followed by CT scan (37.8%). 45.9% of patients had domestic dog and hygiene principles of washing the vegetables was adhered by 6.7% of patients.

Conclusion: The prevalence of human hydatidosis, as a most important neglected disease, should be considered by health policy-makers in public health domain. In addition, educational programs to better recognition of the disease symptoms, and to identify the infection sources are needed in high risk group of population.
