The pattern of cystic echinococcosis in children in an endemic area in Morocco

Cystic Echinococcosis in Hospitalized Children from Western Romania: A 25-Year Retrospective Study

Cystic echinococcosis (CE) is a cosmopolitan parasitic disease caused by Echinococcus granulosus. We aimed to assess the epidemiological aspects of the disease in hospitalized children from Western Romania, a well-known endemic area for CE. We retrospectively investigated the medical records of children hospitalized between 1998 and 2022. A total of 144 patients were included, and 58.3% were from rural areas. The number of cases increased with age, from 9% in the age group 3-5 years to 59.7% in the age group 11-17 years. The liver was more frequently affected (65.3%), and a significant association between gender and the affected organ was noted; liver cysts were more frequently diagnosed in girls, while lung cysts were recorded mostly in boys. Complications were more frequently reported in patients with pulmonary CE compared to hepatic CE (p = 0.04). Boys had more complications (16/23, 69.6%) compared to girls (7/23, 30.4%) (p = 0.03). A third of the children were hospitalized for more than 14 days, and multiple hospitalizations were recorded in 31.3% of the patients. This paper provides new insights into the epidemiologic features of cystic echinococcosis in children from Western Romania. Our findings indicate that exposure to the parasite starts in childhood, and the rate of hospitalization increases with age. Public health strategies should be implemented and permanently improved in order to lower the prevalence of CE in children.

Cystic Echinococcosis in Children: Ten Years of Experience and Which Laboratory Result in Evaluating Ruptured Cases?

Aim Hydatid disease (Echinococcosis) is a common zoonosis in countries that are involved in livestock such as our country. Our study aims to evaluate pediatric cases with hydatid disease over the last decade in our region and to determine the significance of initial clinical and laboratory findings in distinguishing ruptured hydatid cyst cases. Materials and Methods A retrospective analysis was made on demographic characteristics, presenting symptoms, physical examination, laboratory and radiological findings, and treatments of children with hydatid disease who were treated in our hospital and followed up regularly between January 2011 and December 2020. Results The study sample of 42 cases included 19 (45.2%) girls, with a median age of 125.5 (34-209) months. The most common symptom was abdominal pain (50%), and the most common physical examination finding was decreased breath sounds (23.8%). Thirty-five (83.3%) patients had single organ involvement and 7 (16.7) patients had multiple organ involvement. Cysts were detected in the right lobe of the liver in 24 (75%) of hepatic hydatid cysts and the left lobe in 7 (58.3%) of pulmonary hydatid cysts. The median size of the cysts was 57.5 (12-140) mm. The initial IHA titer, eosinophil count, eosinophil percentage, and sedimentation value were statistically significantly higher in patients with ruptured cysts than in those without rupture (p= 0.002, p= 0.003, p= 0.003, p= 0.02, respectively). Conclusions Initial pathological examination findings and at initial laboratory findings such as high IHA titer, eosinophil count, eosinophil percentage, sedimentation value can be used to distinguish rupture cases.

Detection of Echinococcus granulosus sensu lato in Environmental Samples from Ibadan, Oyo State, South West Nigeria

Environmental contamination with parasite eggs poses a serious risk to public health. This study aimed to assess the presence of taeniid eggs and, in particular, E. granulosus s.l., in environmental samples in the city of Ibadan, South West Nigeria. To this purpose, soil (n = 200), fecal (n = 200) and water samples (n = 50) were examined by microscopic observation and the multiplex PCR method. The influence of specific environmental factors on E. granulosus s.l. egg dispersion was also evaluated. Taeniid eggs were microscopically found in 11.5%, 25.5% and 8.0% of soil, fecal and water samples, respectively. PCR analyses evidenced the presence of E. granulosus s.l. in 8.0%, 24.0% and 2.0% of soil, fecal and water samples, respectively. The proximity to slaughterhouses, the level of urbanisation and the local government area of belonging did not seem to affect E. granulosus s.l. egg dissemination patterns. Our results have clearly demonstrated that both urban and semi-urban areas of the city of Ibadan in Nigeria are highly contaminated by taeniid eggs and we recommend the adoption of appropriate measures to control E. granulosus s.l.

Cystic echinococcosis in a Moroccan boy: a silent and neglected disease among refugee and migrant children

We report the unusual case of a 5-year-old migrant boy from a rural area of Morocco with an almost-giant lung hydatid cyst that was an incidental finding on a chest X-ray performed during routine visa procedures. Echinococcus granulosus serology test was initially negative with subsequent positive seroconversion. Albendazole was started at 4 weeks before surgery and maintained for 4 months, with a favourable outcome. Cystic echinococcosis (CE) is considered a neglected tropical disease and affects more than one million people worldwide, mostly from a lower socioeconomic background. Preventive measures have been limited in underdeveloped regions. Children with CE are especially vulnerable, due not only to the high pathogenic potential of the disease but also to their frequent involvement in challenging socioeconomic situations, including migration. The incidence of CE is increasing in Europe because of high immigration flows from endemic countries. Nevertheless, CE is not covered by current migrant screening protocols.
