New guidelines for the diagnosis and treatment of neurocysticercosis: a difficult proposal for patients in endemic countries.

ABSTRACT

INTRODUCTION: Recent guidelines for the diagnosis and treatment for neurocysticercosis (NC) from the Infectious Disease Society of America/American Society of Tropical Medicine and Hygiene were developed to be used in the United States and Canada, where only a small fraction of NC cases occur. Areas covered The paper discusses the strengths and weakness of the proposed guidelines. Expert commentary Although these new guidelines bring much needed attention to a neglected parasitic disease, some of the recommendations made are based on insufficient and/or inadequate evidence. The authors only recommend one specific immunological assay for use in the diagnosis of NC, when evidence clearly supports other options. The authors strongly recommend dual-anthelminthic for patients with multiple active parenchymal cysts on the basis of one clinical trial that was stopped early. The authors recommend surgical removal of cysts in the fourth ventricle and long-term treatment for subarachnoid NC despite their own admission that there is little evidence to support these recommendations. We propose that clinicians should approach some of the recommendations in the new guidelines with caution and call for the establishment of gold-standard guidelines that can be used and adapted for the diagnosis and treatment of patients with NC worldwide.
