An analysis of the topic of the acquired immunodeficiency syndrome

Since the first case was identified inacquired immune deficiency syndrome AIDS has grown into an epidemic that has taken approximatelylives in the United States alone. DuringAIDS caused the deaths of an estimated 3. At this time, women were increasingly affected by AIDS; it was estimated that women comprised approximately 50 percent or

Although a low CD4 cell count has consistently been identified as a risk factor for the development of cancer in HIV-infected patients, the specific immunologic mechanisms associated with HIV infection that increase the risk of cancer remain ill defined.

It is clear that HIV leads to a lack of immunosurveillance to control viral infections, resulting in cancers associated with EBV B-cell lymphoma, Hodgkin lymphoma, and leiomyosarcomaHHV8 Kaposi sarcoma, pleural effusion lymphoma, and Castleman diseaseand HPV cervical and anal neoplasm and skin cancer.

See Chapter 65 for more details about HIV-associated malignancies. Cancer in Patients with Autoimmune disease The risk of lymphoma is increased in patients with autoimmune disease, although the overall incidence remains quite low.

In patients who receive chronic immunosuppressive therapy, the pathogenesis of lymphoma is likely the same as other immune-deficient states.

However, the abnormal immune response and lymphocyte proliferation to chronic antigenic stimulation may also play a role. This risk has been associated with both primary and secondary disease. Of note, neither age nor use of immunosuppressive therapy appears associated with this risk.

Persons with systemic lupus erythematosus appear to have a threefold to sevenfold increased risk of NHL.

The risk appears to be highest in older patients. The risk of NHL in patients with rheumatoid arthritis is increased with the use of immunosuppressive therapy, and use of anti-TNF monoclonal antibody therapy may additionally increase the risk.

Inflammatory bowel disease is not associated with increased risk of NHL. However, persons with celiac disease have an increased incidence of T-cell NHL and enteropathy-type T-cell lymphoma, and persons with Crohn disease have an increased incidence of hepatosplenic T-cell lymphoma.

As opposed to NHL observed in other immune-deficient hosts, it appears that upon adjustment for co-morbidities, patients with autoimmune disease do as well as immunocompetent patients when treated with standard chemotherapy regimens, although the prognosis for enteropathy-type and hepatosplenic T-cell lymphomas is dismal.

This disease occurs because of the delayed T-cell immune reconstitution or T-cell dysfunction associated with aggressive immunosuppression for the treatment of graft-versus-host disease. One large retrospective study identified four high-risk factors: Posttransplant Lymphoma after Solid-Organ Transplantation Three scenarios exist in which immune suppression in persons who undergo SOT may increase the risk of cancer.

The first scenario is the development of de novo cancer in the SOT recipient. The second scenario is the increased risk of recurrence in SOT recipients with a history of cancer.

The third scenario is the risk of cancer transmission from the donor.

De novo Cancer in SOT Recipients Data from several national registries have shown that SOT recipients have an increased risk of cancer compared with the general population. Table summarizes the results from four national registries.

Compared with the general population, SOT recipients tend to have more advanced stage disease and a worse outcome. The use of more intensive and prolonged immunosuppression—especially use of anti—T-cell monoclonal antibody for treatment of graft rejection—has been associated with an increased PTLD risk in patients after SOT.

Therefore the incidence of PTLD is higher in young children compared with adolescents or adults. The incidence of PTLD varies among types of allografts; with abdominal allografts e. Although the incidence of PTLD after organ transplantation has declined, the mortality rate remains problematic.

Reduction of immunosuppression is the first line of therapy, and outcome is good for disease that is responsive to this intervention. Limited disease that is amenable to complete surgical resection is associated with a high rate of durable remissions.

Chemotherapy is usually reserved for the most resistant disease and in the past has been associated with a high treatment-related mortality.HIV stands for human immunodeficiency virus.

It is the virus that can lead to acquired immunodeficiency syndrome, or AIDS, if not treated. Unlike some other viruses, the human body can’t get rid of HIV completely, even with treatment.

Acquired Immunodeficiency Syndrome, also known as AIDS, has considerably influenced society in Sub-Saharan Africa. The prevalence (the number of people living with AIDS) and the incidence (number of new cases) measurements of the epidemic have slowing been decreasing.

HIV The human immunodeficiency virus (HIV) is a lentivirus (a subgroup of retrovirus) that causes HIV infection and acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to .

The human immunodeficiency virus-1 envelope protein gp was shown to induce apoptosis in hippocampal neurons, thus perhaps causing directly the acquired immunodeficiency syndrome dementia syndrome (for references, see Meucci et al., ).

Acquired immune deficiency syndrome (AIDS) is an infectious disease caused by the human immunodeficiency virus. It was first recognized in the United States in AIDS is the advanced form of infection with the HIV virus, which may not cause recognizable disease for a long period after the initial exposure (latency).

Acquired immunodeficiency syndrome (AIDS) is very dangerous disease of the human system caused by infection with Human Immunodeficiency Virus (HIV).

There are 60 million people have been infected with HIV/AIDS and more than 20 million people have died of AIDS. According to strict governmental /5(3).
