Essay On HIV

HIV or the Human Deficiency virus is like other viruses including the flu, but the one thing that makes this virus so different than any other is that the body is unable to clear this one out completely. Once someone is infected, there is no cure. Over time, HIV can also hide or mask itself in the body's cells. The cells within a person's body that fight off infection are called CD4 cells or T cells. HIV attacks these cells and copies or replicates itself inside these cells, then destroys them. HIV over time will destroy so many of these cells that the body is unable to fight off infection anymore. When this starts happening, AIDS or Acquired Immunodeficiency Syndrome happens which is the final stage

The term Human Immunodeficiency Virus is commonly known as (HIV), which is a virus that attacks the immune system of humans by destroying the amount of CD4 cells in their bodies. Without CD4 the human body is unable to fight against diseases, which can lead to Acquired Immune deficiency syndrome known as AIDS for short. The first case of the HIV/AIDS virus in the U.S. occurred in the early 1980’s. The first spark of the virus was found in San Francisco with couple of homosexual Caucasian American males. Today African Americans account for the largest proportion of HIV and AIDS in this country, represent approximately 13% of the U.S. population, but accounted for an estimated 44% of new HIV infections in 2010(the last year a study was

Human Immunodeficiency Virus is HIV that develops into AIDS, which is Acquired immunodeficiency syndrome. This virus starts to break down white blood cells, as a result the immune system starts to deteriorate and our greatest shield cannot fight any longer (Mayo Clinic, 2016). The CDC (2015) states, that over 1.2 million people live with HIV in the United States and most who are infected are oblivious of their disease. Healthy people 2020 has declared HIV a public health crisis in the United States, and continues to sweep the nation with more than 500,000 new cases each year (HealthyPeople2020,2016).

According to recent statistics from the Centers for Disease Control, approximately 1.2 million individuals in the United States have HIV (about 14 percent of which are unaware of their infection and another 1.1 million have progressed to AIDS. Over the past decade, the number of HIV cases in the US has increased, however, the annual number of cases remains stable at about 50, 000 new cases per year. Within these estimates, certain groups tend to carry the burden of these disease, particularly the gay, bisexual, and men who have sex with men (MSM) and among race/ethnic groups, Blacks/African American males remain disproportionately affected. (CDC)

In the 1980s, a mysterious disease began to take the lives of Americans. With the cause unknown, a fear grew among Americans. An unusually high rate of people was becoming sick with strange and rare diseases. When experimental treatments failed to work, people died. This mysterious disease is what we now know as HIV–Human Immunodeficiency Virus. In the past thirty-five years, the HIV has taken many turns in history. Although we do not hear about HIV and AIDS now, it is still a prevalent issue in the United States and in the world.

6. Atherosclerosis, pp.1157. is a form of arteriosclerosis in which thickening and hardening of the vessel are caused by the accumulation of lipid-laden macrophages w/I the arterial wall, which leads to the formation of a lesion called a plaque. It is not a single disease but rather a pathologic process that can affect vascular syustemns throughtout the body, resulting in ischemic syndromes that can vary widely in their severity and clinical manisfestations. It is the leading contributor to coronary artery and cerebrocascular disease. Athrosclerosis is an inflammatory disease, the lesions progress from endothelial injury and dysfunction

Atherosclerosis is the leading cause of coronary heart disease, the number one killer of Americans (). The inflammatory process is known to lead to a myriad of other cardiovascular complications including, coronary heart disease, stroke and myocardial infarctions. It is important

Atherosclerosis develops over the course of 50 years, beginning in the early teenage years. The causes of this process appear to be lipid retention, oxidation, and modification, which provoke chronic inflammation at susceptible sites in the walls of all major conduit arteries. Initial fatty streaks evolve into fibrous plaques, some of which develop into forms that are vulnerable to rupture, causing thrombosis or stenosis. Erosion of the surfaces of some plaques and rupture of a plaque's calcific nodule into the artery lumen also may trigger thrombosis. The process of plaque development is the same regardless of race/ethnicity, sex, or geographic location, apparently worldwide. However, the rate of development is faster in patients with risk

Presently, the treatment strategies used are risk factor modification, conventional pharmacology and surgical revascularization. These strategies have hitherto not been of enormous solution as the disease progression still result in recurrent symptoms. This has now led to the exploitation of advances in comprehending the vascular biology of atherogenesis to introduce novel cell and molecular-based therapies. The application of immunomodulation, lipid-lowering agents like statins, gene transfer, antisense technology and so on has resulted in new therapeutic strategies to interrupt cell proliferation and disorder of the vessel wall. In this essay, immunomudulation and lipid-lowering agent shall be discussed.

Atherosclerosis is a lipid storage disease where too much of lipid is deposited in endothelial of arteries causing narrowing to prevent blood to flow. It is triggered by daily diet of consuming highly saturated fat, hypertension and smoking. In healthy endothelial cells, leukocytes do not stick on to the endothelial cells. During early phases of inflammation in endothelial cells, the leukocytes attach to the arteries cell wall with the help of vascular cell adhesion-1 (VCAM-1) and penentrate into the endothelial layer. VCAM-1 binds monocytes and T lymphocytes, the types of leukocytes found in early atherosclerotic plaques. ( Libby P., 2006:456S) Atherosclerosis lesion is a foam cells whereby macrophages engulf lipid particles. The lesion secretes cytokines and growth factors to promote proliferation of smooth muscle. The increased of inflammatory markers like interleukin 6 (IL-6) and interleukin 1 (IL-1) accumulated in the endothelial cells accerlate the progess of

Cardiovascular infection influences the heart and veins. More than fifty million Americans experience cardiovascular issues and cardiovascular disease is the main source of death and disability in the United States. When the heart issues are known, the hidden cause is generally much progressed. Therefore, prevention through the alteration of risk factors, for example, good dieting, exercise and not smoking is critical. Many of these risk factors are the same factors leading patients to contract periodontal disease. So having periodontal disease can lead to cardiovascular disease later on in life if the patient has chosen not to modify their oral hygiene habits. (Oal Care Center)

HIV and AIDS have affected millions of people throughout the world. Since 1981, there have been 25 million deaths due to AIDS involving men, women, and children. Presently there are 40 million people living with HIV and AIDS around the world and two million die each year from AIDS related illnesses. The Center for Disease Control estimates that one-third of the one million Americans living with HIV are not aware that they have it. The earliest known case of HIV was in 1959. It was discovered in a blood sample from a man in Kinshasa, Democratic Republic of the Congo. Looking further into the genetics of this blood sample researchers suggested that it had originated from a virus going back to the late 1940’s or early 1950’s. In 1999,

Sub-Saharan Africa is the region of the world that is most affected by HIV/AIDS. The United Nations reports that an estimated 25.4 million people are living with HIV and that approximately 3.1 million new infections occurred in 2004. To put these figures in context, more than 60 percent of the people living with the infection reside in Africa. Even these staggering figures do not quite capture the true extent and impact that this disease causes on the continent. In 1998, about 200,000 Africans died as a result of various wars taking place on the continent. In that same year, more than 2 million succumbed to HIV/AIDS (Botchwey, 2000).

HIV is the human immunodeficiency virus that causes AIDS. A member of a group of viruses called retroviruses, HIV infects human cells and uses the energy and nutrients provided by those cells to grow and reproduce. AIDS (acquired immunodeficiency syndrome) is a disease in which the body's immune system breaks down and is unable to fight off certain infections, known as "opportunistic infections," and other illnesses that take advantage of a weakened immune system. When a person is infected with HIV, the virus enters the body and lives and multiplies primarily in the white blood cells. These are the immune cells that normally protect us from disease.

HIV, or the Human Immunodeficiency Virus, is a virus which damages and kills cells of the immune system. It attacks the T-cells, key cells of the immune system, and uses them to make copies of itself. After being infected with the virus it progressively interferes and eventually destroys the immune system's ability to fight the anti-genes. HIV may develop into the syndrome AIDS, the Acquired Immunodeficiency Syndrome. HIV is an STD - a sexually transmitted disease - and therefore most commonly it is spread through sexual contact, and the virus mainly enters the body through the penis, mouth, lining of the vagina or vulva during sexual activity. HIV can also be spread through sharing syringes or needles with someone who is infected with the
