How Is The Immune System Affected By Hiv – Medical Review by Cameron White, MD, MPH — Written by Anne Pietrangelo and Christine Charney — Updated June 30, 2023

HIV destroys CD4 cells, which are responsible for keeping people healthy and protecting against disease and infection. Signs and symptoms may appear as HIV gradually weakens the body’s natural defenses.

How Is The Immune System Affected By Hiv

HIV targets cell types that normally fight off invaders such as HIV. As the virus replicates, it damages or destroys the CD4 cells it infects, producing more virus to infect more CD4 cells. CD4 cells are also called T cells or helper cells.

Without treatment, this cycle continues until your immune system is severely compromised, putting you at risk of serious illness and infection.

Acquired immunodeficiency syndrome (AIDS) is the final stage of HIV. At this stage, the immune system is greatly weakened and the risk of contracting opportunistic infections is very high.

However, not all people infected with HIV develop it. The earlier the treatment, the better the prognosis.

The immune system protects the body from diseases and infections. White blood cells protect the body from viruses, bacteria and other microorganisms that can make you sick.

Hiv And The Immune System

A few days after contracting the virus, people with HIV may have flu-like symptoms that last for several weeks. This is associated with the first phase of HIV, called the acute infectious phase or acute HIV.

At this stage, people living with HIV often have no serious symptoms, but there is usually a large amount of virus in the blood because the virus multiplies rapidly.

The next stage is called the chronic infection stage. It will last 10 to 15 years. People living with HIV may or may not show signs and symptoms at this stage.

Another possible complication, Kaposi’s sarcoma, is cancer of the blood vessel walls. Although rare in the general population, it is more common in people with advanced HIV infection.

What Complications Can Occur With Hiv?

Symptoms include red or dark purple lesions on the mouth and skin. It can also cause problems with your lungs, digestive tract and other internal organs.

HIV and AIDS also increase the risk of developing lymphoma. An early sign of lymphoma is swollen lymph nodes.

HIV makes it harder to fight respiratory diseases like colds and flu. Second, people living with HIV can develop associated infections such as pneumonia.

If HIV is not treated, as the disease progresses, people living with HIV are at greater risk of infectious complications such as tuberculosis and a fungal infection called Pneumocystis jiroveci pneumonia (PJP).

The risk of lung cancer also increases with HIV infection. This is due to weakened lungs due to various respiratory problems associated with weakened immunity.

People with HIV are more likely to develop high blood pressure. HIV also increases the risk of pulmonary arterial hypertension (PAH). PAH is a type of high blood pressure in the arteries that supply blood to the lungs. Over time, PAH can stress the heart and cause heart failure.

Tuberculosis is an airborne bacterium that affects the lungs. It is the leading cause of death in AIDS patients. Symptoms include chest pain and a severe cough that may contain blood or mucus. The cough can last for months.

HIV affects the immune system, making the body more susceptible to infections that can affect the digestive system.

Beating The Odds

Gastrointestinal problems can also reduce appetite, making it difficult to eat properly. As a result, weight loss is a common side effect of HIV.

A common infection associated with HIV is oral thrush. This is a yeast infection that causes inflammation and white patches on the tongue and in the mouth.

Another viral infection that affects the mouth is oral hairy leukoplakia, which causes white lesions on the tongue.

Salmonella infections are spread through contaminated food or water and cause diarrhea, abdominal pain, and vomiting. accessible to all

Is Your Immune System Unhealthy? Why Things Can Go Wrong

This infection affects the bile ducts and intestines and can be particularly serious. It can cause chronic diarrhea in AIDS patients.

HIV does not usually infect nerve cells directly, but it infects cells that support and surround nerves in the brain and throughout the body.

Although the link between HIV and nerve damage is not fully understood, infected supporting cells may contribute to nerve damage.

Advanced HIV can cause nerve damage, also known as neuropathy. This most often causes pain and numbness in the feet and hands.

Small holes in the conducting sheaths of peripheral nerve fibers can cause pain, weakness, and difficulty walking. This condition is known as vacuolar myelopathy.

AIDS has significant neurological complications. HIV and AIDS can cause HIV-related dementia, which has a significant impact on cognitive function.

A weakened immune system puts people with AIDS at increased risk of inflammation of the brain and spinal cord caused by this parasite. Symptoms include confusion, headaches and seizures. Seizures can also be caused by certain infections of the nervous system.

In very advanced cases, hallucinations and overt psychosis may occur. Some people have headaches, problems with balance and coordination, and vision problems.

Researchers Find Genetically Intact Hiv Virus Prefers To ‘hide’ In Organs Of The Immune System

A weakened immune response makes you more vulnerable to viruses such as herpes. Herpes can cause ulcers around the mouth and genitals.

HIV also increases the risk of shingles. Shingles occurs when the virus that causes chickenpox, herpes zoster, reactivates. This condition causes a painful rash, often accompanied by blisters.

A viral skin infection called molluscum contagiosum causes bumps on the skin. Another condition called prurigo nodularis causes scab-like bumps on the skin as well as severe itching.

HIV can cause a variety of symptoms, ranging from mild flu-like symptoms in the early stages to neurological symptoms if the condition progresses to AIDS.

Many of the above effects relate to the immune system, which is constantly compromised in the progression of HIV and AIDS.

However, many of these effects can be prevented with antiretroviral treatments that can maintain and repair the immune system.

Your health care provider may recommend additional treatments, such as blood pressure medication or skin creams, to address the effects of HIV or AIDS on other systems in your body.

Topological Perspective On Hiv Escape

Our experts continuously monitor the field of health and wellness and update articles as new information becomes available.

According to the United Nations, almost 40 million people were living with HIV in 2017, and slightly more than half of them were receiving antiretroviral therapy. These drugs have cut AIDS deaths by more than half since their peak in 2004, but they do not cure the disease. A new mechanism discovered by a Norwegian research group could increase the chances of development.

Since the introduction of antiretroviral treatments for HIV infection in 1996, scientists have been eagerly searching for a cure for this disease.

Although drugs allow people with HIV to lead normal, healthy lives, people with HIV must receive antiretroviral treatment for the rest of their lives. Small amounts of the virus can remain dormant in immune cells for years, so when the patient stops taking the drug, the latent virus can come out of hiding and re-infect the patient. It probably will be.

And now, as the first people to start treatment enter middle age, doctors are focusing on the inflammatory side effects caused by the presence of even trace amounts of HIV in the blood. This is another reason for the development of treatment for this disease.

Research from the Center for Molecular Inflammation Research (CEMIR) at the Norwegian University of Science and Technology (NTNU) has revealed a previously unknown way in which the body’s immune system detects and responds to HIV infection. Treatment.

To understand exactly what the researchers did, we need to re-educate ourselves about how HIV actually works in the body and how the body responds.

When a virus enters the body, it infects the very cells that the body uses to fight the virus. These are called CD4 T helper cells or CD4 T cells.

When T cells become infected, they are no longer able to protect the body against other diseases and infections. Consequently,
