Tetraventricular Hydrocephalus Following Eosinophilic Meningitis due to <i>Angiostrongylus cantonensis</i> in a 14-Month-Old Boy From Mayotte: A Case Report

The safety and efficacy of benzimidazole anthelmintics for the management of rat lungworm disease (neuroangiostrongyliasis) have been questioned regardless of the numerous global experimental animal studies and clinical reports. In this review, 40 of these experimental animal studies and 104 clinical reports are compiled with a focus on albendazole. Among the 144 articles involving an estimated 1034 patients and 2,561 animals, 4.1% were inconclusive or vague regarding the use of benzimidazoles. Of the remaining 138 articles, 90.5% found benzimidazoles to be safe and effective (885 patients; 2,530 animals), 4.3% as safe but ineffective (73 patients; 3 animals), and 5.0% caused adverse reactions (7 patients; 28 animals). Among the clinical reports with a confirmed diagnosis of neuroangiostrongyliasis in which albendazole monotherapy was used, 100% reported high efficacy (743 patients; 479 animals), and in those where albendazole-corticosteroid co-therapy was used, 97.87% were reported to be effective (323 patients; 130 animals).

Terrestrial mollusks, including the invasive giant African snail (Lissachatina fulica), pose significant public health risks due to their role as carriers of various pathogens, such as Angiostrongylus cantonensis and Angiostrongylus costaricensis. This scoping review aims to provide a comprehensive evaluation of diseases associated with Lissachatina fulica and other terrestrial mollusks, with a particular focus on the prevention, diagnosis, and treatment of these conditions. Following the Joanna Briggs Institute guidelines and the PRISMA-ScR framework, we conducted a systematic search and filtered results, identifying 27 relevant case reports and series for analysis. Our findings reveal that ingesting raw or undercooked snails is the most hazardous exposure route, with a 75% mortality rate in affected adults, particularly in regions where snail consumption is culturally significant, such as France. A. cantonensis is the primary cause of eosinophilic meningitis, while A. costaricensis leads to abdominal angiostrongyliasis. The review also highlights the widespread impact of L. fulica in countries like France, the United States, Brazil, and Colombia, emphasizing the global nature of the threat. Children show consistent vulnerability across all exposure types, underscoring the need for targeted preventive strategies. This review underscores the urgent need for public health interventions, particularly educational campaigns to inform communities about the dangers of L. fulica. Additionally, it highlights the importance of enhancing diagnostic methods and expanding surveillance to better manage the risks associated with these invasive snails. The findings provide valuable insights for the scientific community and recommend a multidisciplinary approach to effectively mitigate the public health risks posed by L. fulica across diverse regions.

Objective: Angiostrongylus cantonensis (A. cantonensis) is an important parasite, which causes neurological infection in children, and is generally difficult to diagnose. We analyzed the significance of metagenomic next-generation sequencing in diagnosing A. cantonensis encephalitis/meningitis in children to provide a reference for clinical diagnosis. Methods: The case collection of A. cantonensis encephalitis/meningitis was from July 2018 to August 2020.The patients' clinical characteristics and pathogen were described, and diagnostic sensitivity methods for A. cantonensis encephalitis/meningitis were compared and analyzed, including parasite antibody detection and metagenomic next-generation sequencing (mNGS) detection in different samples. Results: Eleven cases were diagnosed with A. cantonensis encephalitis/meningitis, including six males (54.5%) and five females (45.5%), and the age ranged from 1 to 13 years with a median of 21 months (IQR: 15.6, 96). All patients were undiagnosed upon admission, of which ten cases had neurological symptoms or signs, six cases (54.5%) had a history of definite or suspicious exposure to parasites, and eight cases (72.7%) had abnormal changes in cranial MRI. The results of A. cantonensis antibodies in the peripheral blood and cerebrospinal fluid (CSF) were compared with CSF's metagenomic next-generation sequencing (mNGS). The antibody-positive rate of peripheral blood was 54.5%,
