Abstract

Cystic echinococcosis (CE), the second most significant foodborne parasitic disease worldwide, poses a significant global health burden. Understanding its clinical and laboratory features is crucial for effective management. This study aimed to investigate the epidemiological, laboratory, and clinical characteristics of pediatric CE in an Iranian referral hospital. A cross-sectional study reviewed hospital records of patients with CE admitted to Children’s Medical Center, Tehran, Iran, from 2011 to 2020. Data on demographics, diagnostics, clinical presentation, laboratory findings, and treatment were collected and analyzed. A total of 114 patients, with a mean age of 7.33 – 2.9 years, were diagnosed with CE. The male-to-female ratio was 1.78, and 73.7% were urban residents. Abdominal pain (69%) and coughing (65%) were the most common symptoms. In confirming the cyst involvement across anatomical sites, pathology emerged as the most reliable method, with effectiveness ranging from 95% to 100%. Abdominal ultrasonography and computed tomography scan were frequently utilized imaging modalities, displaying effectiveness percentages of 71–85%. Liver and lung involvement predominated (66%), with 39% of cases showing multiorgan involvement. Spleen involvement was less common (6%), and neurological involvement was rare (1–2%). The majority of patients (n = 63, 67.7%) displayed cysts larger than 50 mm. All patients received albendazole treatment, and 104 patients (91.2%) underwent surgical procedures, with three postsurgical deaths. In conclusion, hospital records over 9 years indicate an increasing prevalence of CE, emphasizing the need for heightened awareness and effective public health interventions to control this parasitic infection. © Mary Ann Liebert, Inc.
