Does Chagas affect the brain?

Chagas disease (CD) remains a major cause of cardiomyopathy and stroke in developing countries. Brain damage in CD has been attributed exclusively to the effects of structural heart disease on the brain, including cardioembolism and low cardiac output symptoms.

What are the neurological symptoms of Chagas?

In the chronic phase, it presents as neuritis that results in altered tendon reflexes and sensory impairment, and is reported in up to 10% of the patients. Isolated cases of central nervous system involvement can also include dementia, confusion, chronic encephalopathy and sensitive and motor deficits.

What are the long term effects of Chagas disease?

If Chagas disease progresses to the long-lasting (chronic) phase, serious heart or digestive complications may occur. These may include: Heart failure. Heart failure occurs when your heart becomes so weak or stiff that it can't pump enough blood to meet your body's needs.

What organ system does Chagas disease affect?

Chagas disease is an infectious disease caused by the protozoan Trypanosoma cruzi. The disease mainly affects the nervous system, digestive system and heart.

How long can a person live with Chagas disease?

Chagas disease has an acute and a chronic phase. If untreated, infection is lifelong. Acute Chagas disease occurs immediately after infection, and can last up to a few weeks or months.

KILLER DISEASES | How Chagas Disease Affects the Body

Is Chagas disease permanent?

It is estimated that as many as 8 million people in Mexico, Central America, and South America have Chagas disease, most of whom do not know they are infected. If untreated, infection is lifelong and can be life threatening.

How do doctors test for Chagas?

The diagnosis of Chagas disease can be made by observation of the parasite in a blood smear by microscopic examination. A thick and thin blood smear are made and stained for visualization of parasites.

Can you recover from Chagas disease?

Treatment. To kill the parasite, Chagas disease can be treated with benznidazole or nifurtimox. Both medicines are nearly 100% effective in curing the disease if given soon after infection at the onset of the acute phase, including the cases of congenital transmission.

What is the major concern for chronic Chagas disease patients?

Nearly 30% of chronically-infected patients become symptomatic, often with a latency of 10-30 years, developing life-threatening complications. Of those, nearly 90% develop Chagas heart disease, while the others manifest gastrointestinal disease and neuronal disorders.

How rare is Chagas disease?

Chagas disease is common in parts of Mexico, Central America, and South America where an estimated 8 million people are infected.

Can you cure chronic Chagas?

Once Chagas disease reaches the chronic phase, medications won't cure the disease. But, the drugs may be offered to people younger than age 50 because they may help slow the progression of the disease and its most serious complications.

Does Chagas need to be treated?

Treatment for Chagas disease is recommended for people diagnosed early in the course of infection (acute phase), babies with congenital infection, and for those with suppressed immune systems. Many patients with chronic infection may also benefit from treatment.

What organ is targeted during an infection with T cruzi?

Bone Marrow Is a Target Organ in Orally Induced Trypanosoma cruzi Acute Infection. During the acute phase of oral T.

What is the drug of choice for Chagas disease?

* Benznidazole is FDA-approved for the treatment of Chagas disease (American trypanosomiasis) caused by Trypanosoma cruzi in pediatric patients 2–12 years of age.

Why is Chagas a silent disease?

Chagas disease is prevalent among poor populations of continental Latin America but is increasingly being detected in other countries and continents. It is often termed as a “silent and silenced disease” as the infected majority have no symptoms or extremely mild symptom.

Should I get tested for Chagas?

A specific test is necessary for the diagnosis of Chagas disease. The test detects the presence of the infection through analysis of a blood sample. Anyone who suspects that they may have Chagas disease should ask their doctor to order this test.

How much is a Chagas test?

Results: The cost of Chagas' disease test in the blood bank of Seccional Bolívar was COP$ 37,804 (USD$ 12), and the blood bag and immunohematology test costs were COP$ 25,941 (USD$ 8.2) and COP$ 6,800 (USD$ 2.2), respectively.

Does ivermectin treat Chagas disease?

In conclusion, although ivermectin treatment may have a transient effect on peridomestic populations of Triatominae, it is not the treatment of choice for this situation.

Where is Chagas disease most common?

It is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors and is found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread).

What is the difference between acute and chronic Chagas disease?

The natural history of Chagas disease is divided into two phases, acute and chronic. The acute phase lasts approximately 8 weeks, and usually causes mild or no symptoms. Patients with chronic Chagas disease have lifelong infection in absence of treatment. Spontaneous cure is extremely rare.

What are the stages of Trypanosoma cruzi?

The life cycle of Trypanosoma cruzi involves two intermediate hosts: the invertebrate vector (triatomine insects) and the vertebrate host (humans) and has three developmental stages namely, trypomastigotes, amastigotes and epimastigotes [8].

Which is a good diagnostic indication of acute Chagas infection?

Acute infections can be diagnosed by parasitologic methods, including identification of trypomastigotes in blood by microscopy. Circulating parasite levels decrease rapidly within a few months and are undetectable by most methods during the chronic phase.

What does Chagas do to the heart?

Chagas cardiomyopathy represents the most frequent and serious complication of chronic Chagas disease, affecting about 20-30% of patients, potentially leading to heart failure, arrhythmias, thromboembolism, stroke and sudden death.

Should I be worried about Chagas disease?

Decades after being infected, about 30 percent of those who have Chagas develop serious health effects, including cardiomyopathy (disease of the heart muscle), heart failure, heart rhythm problems, and strokes. Less common are disorders that affect the digestive system.

How common is Chagas disease in USA?

More than 5 million people worldwide have Chagas disease. In the United States, there are estimated to be at least 300,000 cases of chronic Chagas disease among people originally from countries of Latin America where Chagas disease is endemic.
