The purpose of this protocol is to allow diagnosis, evaluation, treatment and follow up of patients with cysticercosis, while allowing for sample collection to improve diagnostic assays and explore host-parasite interactions. Cysticercosis is defined as an infection with the larval form of Taenia solium and includes infection of the brain (neurocysticercosis) that accounts for most of the symptomatic disease and serious complications. Evaluation and treatment follows accepted clinical practice and information learned is observational. Two drugs, praziquantel and albendazole, have been used extensively in the treatment of cysticercosis and are the accepted therapies. Albendazole is approved for the treatment of cysticercosis while praziquantel is not approved by the FDA but has proven efficacy and safety, and combined therapy is now standard of care to treat NCC. To decrease the treatment-provoked inflammation systemic corticosteroids and/or other immunosuppressive agents will be used. Anti-seizure medications are also commonly used.
