Anthelminthic Agents01:15

Anthelminthic Agents

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
American Trypanosomiasis01:22

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Summary

Neurocysticercosis, a tapeworm infection, is a leading cause of acquired seizures globally. Treatment with antiparasitic drugs like albendazole and preventative measures are key to managing this condition.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Parasitology

Background:

  • Neurocysticercosis is the most common cause of acquired seizures worldwide.
  • It is caused by the larval stage of the pork tapeworm, Taenia solium.
  • Cases are increasing in the United States, particularly among Hispanic immigrants.

Purpose of the Study:

  • To investigate the immunologic and biochemical aspects of Taenia solium persistence in hosts.
  • To review diagnostic and therapeutic strategies for neurocysticercosis.
  • To explore long-term prevention methods.

Main Methods:

  • Diagnosis relies on clinical presentation, radiological imaging, and serological tests.
  • Therapeutic approaches include antiparasitic agents (e.g., albendazole) and surgical interventions.
  • Prevention strategies focus on pork husbandry, sanitation, mass chemotherapy, and vaccination.

Main Results:

  • Antiparasitic therapy is effective for high-burden or centrally located cysts.
  • Cysticidal therapy in patients with enhancing lesions may reduce seizure recurrence.
  • Surgery is indicated for specific neuroanatomic locations.

Conclusions:

  • Neurocysticercosis presents primarily with seizures, but hydrocephalus can occur.
  • Effective management involves antiparasitic treatment, particularly albendazole, and potentially surgery.
  • Prevention necessitates improved sanitation, pork safety, and public health interventions.
