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...
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
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...
Myasthenia Gravis: Diagnostic Tests01:15

Myasthenia Gravis: Diagnostic Tests

Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Area of Science:

  • Infectious Diseases
  • Parasitology
  • Public Health

Background:

  • American Trypanosomiasis, or Chagas' disease, caused by Trypanosoma cruzi, is endemic in the Americas.
  • Imported Chagas' disease presents a transfusion risk in non-endemic countries due to migration.
  • Chronic Chagas' disease impacts blood transfusion safety.

Purpose of the Study:

  • To review strategies for reducing Trypanosoma cruzi transmission via blood transfusion.
  • To compare blood donation policies in endemic and non-endemic regions.
  • To discuss laboratory assays for detecting T. cruzi antibodies.

Main Methods:

  • Review of current blood donation policies and screening strategies.
  • Analysis of diagnostic assays for Trypanosoma cruzi infection.
  • Comparison of approaches in endemic versus non-endemic countries.

Main Results:

  • Endemic countries mandate universal T. cruzi screening.
  • Non-endemic countries employ donor deferral or laboratory testing.
  • Immunologic assays with recombinant antigens are common; IIF and immunoblot aid specificity.

Conclusions:

  • Effective strategies are needed to mitigate transfusion-transmitted Chagas' disease.
  • Harmonizing screening policies globally is essential.
  • Accurate diagnostic tools are vital for blood safety.
