RESUMO

@#Neurocysticercosis (NCC) is a parasitic infection of the nervous system and is responsible for considerable morbidity and mortality. Praziquantel (PZQ) is one of the antiparasitics mostly used in managing NCC, however, there have been only a few studies on the treatment outcome of this drug. The present study aimed to evaluate the efficacy and safety of PZQ in patients with NCC. Sixty patients with typical characteristics of NCC received three 10-day cycles of PZQ and the interruption between these cycles was 10 days. Additional treatment included antiinflammation (steroids), antiepileptics and analgesics. Clinical and imaging studies were done at baseline and six months after therapy to assess the efficacy of treatment. Laboratory evaluation was done before and after each cycle to investigate laboratory safety profiles. By six months after finishing therapy, all patients had clinical improvement and 75% of them were free of symptoms. The rates of complete, partial or no resolution of cysts on brain magnetic resonance imaging were 61.7%, 28.3% and 10% respectively. The efficacy of therapy was not associated with the number of cysts. There was no difference between the levels of aspartate aminotransferase, alanine aminotransferase, urea and creatinine before and after treatment. Conclusion: Praziquantel is effective and safe in the treatment of patients with neurocysticercosis.

RESUMO

@#Raw or undercooked fish dishes are the major sources of human infection of fishborne trematodes (FBT) and the situation of metacercarial infection in fish greatly affect the prevalence in humans, especially those fish that are commonly used for raw consumption. To investigate the situation of infection with metacercaria of FBT in fish often used to prepare raw fish dishes by local people to assess the risk of infection to humans in Ninh Binh province, Vietnam. 345 fish belonging to five species of freshwater and one species of brackish water fish were collected from fishermen or small-scale fish dealers in Kim Son and Yen Khanh districts, Ninh Binh province between May 2017 and May 2018. Metacercaria of FBT was discovered by pepsin and hydrochloric acid digestion techniques and identified by the morphological and molecular analysis. Among examined fish, 44.06% infected with FBT metacercaria and the highest prevalence was in Cyprinus carpio (86.54%), Ctenopharyngodon idellus (78.43%) and Hypophthalmichthys molitrix (66.67%) while Konosirus punctatus – the brackish water fish – were free from infection. Three species of FBT were found; namely Haplorchis pumilio (accounting for 99.84% of collected metacercariae), Haplorchis taichui and Clonorchis sinensis. The average density was 1.06 metacercariae per gram of freshwater fish and the highest number was of C. idellus (6.38 cysts/gram) followed by Cirrhinus molitorella and C. carpio. Results of the study show the high prevalence of infection of FBT metacercariae among freshwater fish often used to prepare raw fish dishes in Ninh Binh province. These findings suggest the need for greater awareness of the risk from raw fish dishes among public health authorities and people.
