The human T-lymphotropic virus type 1 is also known by the acronym HTLV-1, or as human T-cell leukaemia virus type 1. The virus can cause a type of cancer called adult T-cell leukaemia/lymphoma (ATL). What is human T-cell lymphotropic virus symptoms?
Initial symptoms are subtle and include gait problems, unexplained falls, low back pain, constipation, urinary urgency/incontinence and numbness or pain in the lower limbs. Over the years, progressive leg weakness ensues followed by the exacerbation of the urinary and sensory symptoms.
How is HTLV-1 transmitted?
Transmission of HTLV-I occurs from mother to child (18), by sexual contact (19), by blood transfusion (20), and by sharing contaminated needles. What is the difference between HTLV-1 and 2?
HTLV-1 is the causal agent of adult T-cell leukemia and a progressive neurological disorder called HTLV-1-associated myelopathy/tropical spastic paraparesis (12, 34, 54). In contrast, HTLV-2 is essentially nonpathogenic, although a few cases of neurological disease in HTLV-2-infected individuals have been reported.
Can HTLV-1 be cured?
There is no cure or treatment for HTLV-1 and it is considered a lifelong condition; however, most (95%) infected people remain asymptomatic (show no symptoms) throughout life. Should I be worried about HTLV?
Although a few individuals have severe symptoms, most patients remain asymptomatic throughout their lives and their infections may be unknown to many health professionals. HTLV-1 can be considered a neglected public health problem and there are not many studies specifically on patients’ needs and emotional experiences.
Frequently Asked Questions(FAQ)
Does CMV go away?
There’s no cure for CMV. The virus stays inactive in your body and can cause more problems later. This reactivation is most common in people who’ve had stem cell and organ transplants.
What country is HTLV-1 found?
HTLV-1 is present throughout the world, with clusters of high endemicity located often nearby areas where the virus is nearly absent. The main HTLV-1 highly endemic regions are the Southwestern part of Japan, sub-Saharan Africa and South America, the Caribbean area, and foci in Middle East and Australo-Melanesia.
Is HTLV an Oncovirus?
HTLV-I, in particular, is considered as an oncovirus cause of lymphoproliferative disease such as adult T cell leukemia/lymphoma (ATL) and disturbs the immune responses which results in HTLV-I associated meylopathy/tropical spastic parapresis (HAM/TSP).
How long does HTLV live outside the body?
PHYSICAL INACTIVATION: Can be inactivated by steam sterilization at 121ºC for a minimum of 15 minutes and UV light 14. SURVIVAL OUTSIDE HOST: HTLV-1 and HTLV-2 can survive in stored blood for 8-9 days 15.
What do oncogenes cause?
Is HTLV serious?
Of the 5-20 million people infected with the HTLV-1 virus worldwide, approximately 0.25 to 3 percent of the infected individuals will develop HAM/TSP. (An additional two percent of people infected with the HTLV-1 virus will develop a serious blood cancer (adult T-cell leukemia or lymphoma).)
Is HTLV asymptomatic?
Most HTLV-I infected individuals remain lifelong asymptomatic carriers, while 2-5% may develop adult T-cell leukemia/ATL and 0.25-3.8% may develop HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) 4 .
Is HTLV rare?
Dear M.B.: Human T-cell lymphotropic viruses are rare in the U.S. and Canada, and 95% of people with the virus found in their blood will never develop symptoms. However, they can cause two different diseases: adult T cell leukemia-lymphoma, and HTLV-1-associated myelopathy, also called tropical spastic paraparesis.
What does HTLV positive mean?
A positive HTLV-I/II molecular test indicates that the person tested has an HTLV-I or HTLV-II infection. If the molecular result is negative, then the person is less likely to be infected, but it cannot be ruled out as the amount of virus in the blood may have been too low to detect at the time of the test.
How common is HTLV in us?
In the USA, it is estimates that approximately 266,000 individuals are infected with HTLV-1 or -2, and that 3,600 people with HAM/TSP remain undiagnosed.
What is a HTLV-1 2 test for?
Human T-Cell Lymphotropic Virus 1 and 2 (HTLV-1/HTLV-2) Antibodies Blood Test. The HTLV-1/HTLV-2 Antibodies Blood Test is used to screen patients for infection with the human T-lymphotropic virus. Preparation: No special preparation required. Test Results: 5-6 days.
Will I get sick from HTLV?
Unlike HIV, which almost invariably makes you ill, only 2 to 6 percent of [people infected with HTLV-1] will ever develop an illness, Schaffner told Live Science.
Who should be tested for HTLV?
This test is recommended for any individual who has multiple sexual partners; especially those from HTLV prevalent areas such as SW Japan, the Caribbean, and parts of Africa, is an IV drug user, has shared needles, or has had a blood transfusion. Antibodies to HTLV may take up to 3 months to be present in the body.
Does T virus exist?
This is why there are currently no viruses that affect humans, plants, fungi, and animals all at the same time. The Progenitor Virus couldn’t exist today as a plant virus that spreads to humans.
Who is at risk for HTLV?
The overall prevalence of HTLV-1 infection in a sample of MHD patients was similar to that of other viral infections, such as hepatitis B and C. Our data revealed that MHD patients who are older, unmarried or who have received blood transfusions are at higher risk for HTLV-1 infection.
Does HTLV-1 cross the placenta?
The placenta can be infected by HTLV-I, but infection does not reach the fetus, possibly apoptosis of placental villous cells because it is induced by HTLV-I infection.
Can you donate blood if you have HTLV?
Must not donate. HTLV (Human T Cell Lymphotropic Virus I and II) infection can cause serious blood and nervous system disease. It is known to be transmitted by transfusion.
How did I get CMV virus?
People with CMV may pass the virus in body fluids, such as saliva, urine, blood, tears, semen, and breast milk. CMV is spread from an infected person in the following ways: From direct contact with saliva or urine, especially from babies and young children.
What happens if you are CMV positive?
The majority of children born who experience a CMV infection before birth are healthy and normal. However, 10 to 15% may have complications such as hearing loss, neurological abnormalities, or decreased motor skills. Infants who are infected with CMV after they are born rarely experience any long-term complications.
Is cytomegalovirus similar to Covid 19?
These are similar to those produced in COVID-19 patients. Thus, both viruses activate similar immune pathways and CMV may hence contribute to the cytokine storm in COVID-19 patients. This cytokine storm combined by a weakened interferon response seem to contribute to the severe forms of COVID-19 disease .
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
