Angiostrongylus cantonensis
Angiostrongylus
Meningitis
Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (CARCINOMATOUS MENINGITIS), and other inflammatory conditions may produce this syndrome.

Hawaii
A group of islands in Polynesia, in the north central Pacific Ocean, comprising eight major and 114 minor islands, largely volcanic and coral. Its capital is Honolulu. It was first reached by Polynesians about 500 A.D. It was discovered and named the Sandwich Islands in 1778 by Captain Cook. The islands were united under the rule of King Kamehameha 1795-1819 and requested annexation to the United States in 1893 when a provisional government was set up. Hawaii was established as a territory in 1900 and admitted as a state in 1959. The name is from the Polynesian Owhyhii, place of the gods, with reference to the two volcanoes Mauna Kea and Mauna Loa, regarded as the abode of the gods. (From Webster's New Geographical Dictionary, 1988, p493 & Room, Brewer's Dictionary of Names, 1992, p2330)
Strongyloidea
Jamaica
An island in the Greater Antilles in the West Indies. Its capital is Kingston. It was discovered in 1494 by Columbus and was a Spanish colony 1509-1655 until captured by the English. Its flourishing slave trade was abolished in the 19th century. It was a British colony 1655-1958 and a territory of the West Indies Federation 1958-62. It achieved full independence in 1962. The name is from the Arawak Xaymaca, rich in springs or land of springs. (From Webster's New Geographical Dictionary, 1988, p564 & Room, Brewer's Dictionary of Names, 1992, p267)

Angiostrongylus cantonensis eosinophilic meningitis. (1/105)
In the past 50 years, Angiostrongylus cantonensis, the most common cause of eosinophilic meningitis, has spread from Southeast Asia to the South Pacific, Africa, India, the Caribbean, and recently, to Australia and North America, mainly carried by cargo ship rats. Humans are accidental, "dead-end" hosts infected by eating larvae from snails, slugs, or contaminated, uncooked vegetables. These larvae migrate to the brain, spinal cord, and nerve roots, causing eosinophilia in both spinal fluid and peripheral blood. Infected patients present with severe headache, vomiting, paresthesias, weakness, and occasionally visual disturbances and extraocular muscular paralysis. Most patients have a full recovery; however, heavy infections can lead to chronic, disabling disease and even death. There is no proven treatment for this disease. In the authors' experience, corticosteroids have been helpful in severe cases to relieve intracranial pressure as well as neurologic symptoms due to inflammatory responses to migrating and eventually dying worms. (+info)Jejunal perforation caused by abdominal angiostrongyliasis. (2/105)
The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment. (+info)MR findings of eosinophilic meningoencephalitis attributed to Angiostrongylus cantonensis. (3/105)
Eosinophilic meningoencephalitis is prevalent and widely distributed in Thailand, especially in the northeastern and central parts of the country. Angiostrongylus cantonensis is one of the causative agents of fatal eosinophilic meningoencephalitis. The nematodes produce extensive tissue damage by moving through the brain and inducing an inflammatory reaction. We report the clinical features and the findings revealed by MR imaging and MR spectroscopy in six patients with eosinophilic meningoencephalitis. The clinical presentation included severe headache, clouded consciousness, and meningeal irritation. Abnormal findings on MR images included prominence of the Virchow-Robin spaces, subcortical enhancing lesions, and abnormal high T2 signal lesions in the periventricular regions. Proton brain MR spectroscopy was performed in three patients and was abnormal in one severe case, showing decreased choline in a lesion. Small hemorrhagic tracts were found in one case. Lesions thought to be due to microcavities and migratory tracts were found in only one case. We believe the MR imaging and MR spectroscopy findings are of diagnostic value and helpful in understanding the pathogenetic mechanisms of the disease.

Angiostrongylus cantonensis, the rat lungworm, is the principal cause of eosinophilic meningitis worldwide, and the increase in world travel and shipborne dispersal of infected rat vectors has extended this parasite to regions outside of its traditional geographic boundaries. We report a case of eosinophilic meningitis due to A. cantonensis in a patient who recently returned from a trip in the Pacific. (+info)An outbreak of eosinophilic meningitis caused by Angiostrongylus cantonensis in travelers returning from the Caribbean. (5/105)
BACKGROUND: Outbreaks of eosinophilic meningitis caused by the roundworm Angiostrongylus cantonensis are rarely reported, even in regions of endemic infection such as Southeast Asia and the Pacific Basin. We report an outbreak of A. cantonensis meningitis among travelers returning from the Caribbean. METHODS: We conducted a retrospective cohort study among 23 young adults who had traveled to Jamaica. We used a clinical definition of eosinophilic meningitis that included headache that began within 35 days after the trip plus at least one of the following: neck pain, nuchal rigidity, altered cutaneous sensations, photophobia, or visual disturbances. RESULTS: Twelve travelers met the case definition for eosinophilic meningitis. The symptoms began a median of 11 days (range, 6 to 31) after their return to the United States. Eosinophilia was eventually documented in all nine patients who were hospitalized, although on initial evaluation, it was present in the peripheral blood of only four of the nine (44 percent) and in the cerebrospinal fluid of five (56 percent). Repeated lumbar punctures and corticosteroid therapy led to improvement in symptoms in two of three patients with severe headache, and intracranial pressure decreased during corticosteroid therapy in all three. Consumption of one meal (P=0.001) and of a Caesar salad at that meal (P=0.007) were strongly associated with eosinophilic meningitis. Antibodies against an A. cantonensis--specific 31-kD antigen were detected in convalescent-phase serum samples from 11 patients. CONCLUSIONS: Among travelers at risk, the presence of headache, elevated intracranial pressure, and pleocytosis, with or without eosinophilia, particularly in association with paresthesias or hyperesthesias, should alert clinicians to the possibility of A. cantonensis infection. (+info)Enzootic Angiostrongylus cantonensis in rats and snails after an outbreak of human eosinophilic meningitis, Jamaica. (6/105)
After an outbreak in 2000 of eosinophilic meningitis in tourists to Jamaica, we looked for Angiostrongylus cantonensis in rats and snails on the island. Overall, 22% (24/109) of rats harbored adult worms, and 8% (4/48) of snails harbored A. cantonensis larvae. This report is the first of enzootic A. cantonensis infection in Jamaica, providing evidence that this parasite is likely to cause human cases of eosinophilic meningitis. (+info)Immunoblot evaluation of the specificity of the 29-kDa antigen from young adult female worms Angiostrongylus cantonensis for immunodiagnosis of human angiostrongyliasis. (7/105)
The antigenic components of Angiostrongylus cantonensis young adult female worm somatic extract (FSE) were revealed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting. The sera tested were from patients with proven angiostrongyliasis, other parasitic diseases, and healthy adults. Both the sera and cerebrospinal fluid (CSF) were tested from patients with clinical angiostrongyliasis. The CSF from patients with other neurological diseases were also included. Using SDS-PAGE, we found that the FSE comprised more than 30 polypeptides. Immunoblot analysis revealed at least 12 or 13 antigenic bands in patients with proven or clinical angiostrongyliasis, respectively. The patterns of reactivity recognized by the serum and CSF antibodies against FSE were similar. These antigenic components had molecular masses ranging from less than 14.4 to more than 94 kDa. The prominent antigenic band of 29-kDa might serve as a reliable marker for the diagnosis of angiostrongyliasis. The sensitivity, specificity, positive and negative predictive values of immunoblot analysis in this antigenic band were 55.6%, 99.4%, 83.3% and 97.4%, respectively. (+info)A clinical study of eosinophilic meningoencephalitis caused by angiostrongyliasis. (8/105)
OBJECTIVE: To improve the clinician's awareness of angiostrongyliasis. METHODS: The clinical and laboratory data as well as the epidemiological information concerning 18 patients with eosinophilic meningoencephalitis caused by Angiostrongylus cantonensis were analyzed. RESULTS: All patients had a history of eating raw fresh water snail (Ampularium canaliculatus) before the onset of the disease. Incubation period ranged from 1 to 25 days. The major symptoms of the patients had severe headache and pain in the trunk and limbs. Increased eosinophlic count in peripheral blood and cerebrospinal fluid was noted. Tested by enzyme-linked immunoadsorbent assay (ELISA), sera were specifically IgG-antibody positive against Angiostrougylus cantonensis antigen, but were negative against other parasitic antigens such as Paragonimus westermani, Cysticerus, Cellulosae hominis, Echinococcus granulosus and Trichinella spiralis. Abnormal spotty signals were found in 2 cases with brain magnetic resonance imaging. Electroencephalogram (EEG) showed slow alpha rhythm. All the patients were effectively treated with combined administration of albendazole and dexamethazone. CONCLUSIONS: Angiostrongyliasis is one of the common causes leading to eosinophilic meningoencephalitis. To our knowledge, Wenzhou is the first small outbreak site of angiostrongyliasis discovered in Chinese mainland. (+info)
