Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

But what makes HIV able to avoid the immune system?

But what makes HIV able to avoid the immune system?

Hiding inside cells: The HIV is able to avoid the immune system because of its ability to hide inside the cells. The antibodies your body makes to prevent future infections cannot enter the cells, thus they are useless once the HIV is already inside. While inside, they can multiply and thus continue to cause disease for years. So, the best treatment we have =prevention. Live well, evangelineli1. Good luck. ...Read more

We got very good immune system but why is it that we can't fight hiv?

We got very good immune system but why is it that we can't fight hiv?

Immune system attack: Good evening,
it is an insightful question! HIV agent attacks the immune cells themselves while most other infectious agents are attacked by cells of immune system as soon as they enter our body. Hiv enters the immune cells, kills them, causes programmed cell death of cells, and we lose cell-mediated immunity. This makes us defenseless against other invading organism and normally harmless germs. ...Read more

Is HIV able to be detected very soon in the immune system? And how soon?

Is HIV able to be detected very soon in the immune system? And how soon?

HIV window period: Most people develop HIV antibodies within 2-8 weeks of their infection. The average is 25 days. 97% of people will develop detectable antibodies in the first 3 months. Rarely, it can take up to 6 months to develop antibody. If there's concern about acute hiv, a test that measures HIV RNA viral load can be done. The time between HIV infection and RNA detection is about 10 days. Talk with md. ...Read more

How much time it will take to damage immune system in Hiv if we stop ART AND what is condition?

HIV destroys body: Over time, the virus will destroy the immune system. It depends 'where' the patient is starting off from in terms of 'full strength' or not. If the patient is already on ART, then perhaps some damage has already occurred to the immune system. I don't trust the virus & I would not let it 'take' any more immune function from the patient. Besides, even one infection like pneumonia can kill. Take care ...Read more

How long can people with normal immune system live now with HIV medications?

A normal life: Essentially a near normal life. National data from the nih and cdc show the average life expectancy to be measured just several years short of what would otherwise be expected. It is essential though to have routine follow ups with a qualified infectious disease specialist. ...Read more

Is it true that when I get infected by HIV my immune system will be weeked in less than a month?

What are you asking?: WHEN you get infected by HIV? Hopefully, this will NEVER happen. You mean IF, correct? And the answer is, "Yes"; during the acute illness your T-cells will drop precipitously, then rebound. It sounds as it you need to talk with a reality-focused physician. If you are in a relationship with someone who is HIV+, you can be protected. ...Read more

Can you tell me how aids/hiv drugs help patients immune system?

HIV treatment: There are numerous classes of anti-retrovirals to treat HIV/AIDS. Their mechanisms of action are different, but the end result is the same. They all act to decrease viral replication, causing a decrease in the viral load in the blood as well as a gradual increase in the CD4 - T helper - cells. This helps to boost back the immune system. ...Read more

If I get infected by HIV, will my immune system be weakened in less than a month?

Yes: Very much so. During the acute illness, CD4 levels have dropped so low that quite a few people have gotten pneumocystis. Happily, they bounce back and hopefully the illness can be managed. Now why are you asking? I hope all's well. Your physician can help you if you're worried about having become infected, and I hope you'll be safe and not end up at risk. ...Read more

Is it possible that if a person become in contact with HIV through sex and the virus is at a low level, can the immune system fight it off?

Is it possible that if a person become in contact with HIV through sex and the virus is at a low level, can the immune system fight it off?

HIV: There is a rare subgroup of individuals who have an altered version of the viral attachment site for the cell. Generally this means that the infection progresses less rapidly, but prevention is conceivable. Transmission is never 100% and the lower the viral load the lower the risk of infection, but not because the immune system fights it off. ...Read more

What immune system cells are directly affected by the HIV infection?

Easy answer: All cells bearing the CD4 protein are prone to be invaded directly. This is mostly the big class of T-helper cells and the dendritic macrophage family. You'll go crazy if you study the molecules in depth; this is your best answer to a first approximation. ...Read more

What would a person look like in the late stage of HIV or with aids. Due to the fact the immune system is already weak!

Normal, need test: This is the second time you've asked a similar question. Most people with HIV look healthy even with a weak immune system. Sometimes there is weight loss, dry skin, and fatigue, but even with advanced AIDS, most people look fine. If you are worried someone you know might have HIV or is at risk, suggest testing. For sure do not judge a possible sex partner by appearance. ...Read more

If a person has HIV, is it a good idea for that person to consume supplements that are supposed to support or stimulate the immune system?

If a person has HIV, is it a good idea for that person to consume supplements that are supposed to support or stimulate the immune system?

Be discerning: Get a gym membership instead. Exercise is better-evidenced as enhancing immunity than any pill. If you believed a tenth of the claims about herbals, minerals and so forth stimulating the immune system, you would be reading uncritically. If you are interested in supplements, get with an ethical, evidence-based holiday like Healthtap's Randy Baker in your own community. ...Read more

If u r in good health, & have a strong immune system, is it way less likely that you'll get hiv, even if you had unprotected sex w/ infected person? ?

If u r in good health, & have a strong immune system, is it way less likely that you'll get hiv, even if you had unprotected sex w/ infected person? ?

Why do you ask?: Hiv is more likely to be transmitted if the infectious load falls on an area that's already abraded / ulcerated / inflamed. "strong immune system" is hard to measure, but many people who have been exposed but not infected have antibodies in surface fluids. Most important, though, don't assume you're safe just because you're healthy and take care of yourself. ...Read more

My immune system is compromised by hiv, will there be complications with a leishmaniasis infection?

Maybe: Leishmania comes in two forms: the skin (cutaneous) form and the internal (visceral) form which are transmitted by bites from sand flies. These parasites live inside of your cells, causing chronic non-healing sores or large spleens, fever & low blood counts. People with lowered immunity can have activation of old infection or increased susceptibility to new infection. See a specialist fo treatment. ...Read more

im 30 yrs old and Had unprotected sex 4 months ago, 4 weeks ago developed shingles on my back. Weak immune system, HIV positive? No prior symptoms.

Too important: Your request is too important to pass on even though it's confusing. If you're asking about chances of having contracted HIV 4 mths ago, definitely have a test and counseling and always use protection. If you know you are HIV+, please be responsible and avoid spreading it to others. Shingles has been seen to emerge in newly HIV infected folk, so please do test, DX and treat whatever you have! ...Read more

Can a medrol (methylprednisolone) dose pack affect the chances of catching HIV after an exposure? Still negative but concerned since steroids lower the immune system.

Can a medrol (methylprednisolone) dose pack affect the chances of catching HIV after an exposure? Still negative but concerned since steroids lower the immune system.

Theoretically: Steroids can lower your immune resistance to infections, so we must always weigh the risks vs benefits when taking any medication. That being said, a Medellin dose pack is a fairly low dose steroid and only for a short duration so the risks are less. ...Read more
