Enzyme-linked immunosorbent assay (ELISA): This screening test is often used to detect HIV antibodies. For this test, a sample of blood is sent to a laboratory to be analyzed. This test requires complex equipment and waiting for laboratory results
Medications are also used to prevent opportunistic infections (such as Pneumocystis carinii pneumonia) and can keep AIDS patients healthier for longer periods of time. Opportunistic infections are treated as they occur.

A long time ago, some people got HIV from infected blood transfusions. But now, giving or getting blood in medical centers is totally safe. Doctors, hospitals, and blood donation centers don’t use needles more than once, and donated blood is tested for HIV and other infections.
The number of new infections worldwide continues to rise, particularly in women, and effective drug treatments have not yet reached the vast majority of infected individuals in resource-limited countries.In addition, patients require high adherence to the therapy to achieve viral suppression and prevent the development of a drug-resistant virus. Modern regimes are less onerous than older ones. They are simpler and involve fewer tablets, whereas it used to be necessary to take 16 to 20 tablets a day.

The treatment for each immunodeficiency disorder will depend on the specific conditions. For example, AIDS causes several different infections. Your doctor will prescribe medications for each infection. And you may be given an antiretroviral to treat and HIV infection if appropriate.

The first available drug in this class was RAL, which is very potent at suppressing HIV in all patients who have never been on this drug or others in the class. It was initially approved for treatment-experienced patients with drug-resistant virus. It is also now approved for those starting therapy for the first time. The approved dose of RAL is 400 mg twice daily with a recently approved new formulation that can be given to those starting therapy for the first time or stably suppressed on RAL twice daily that can be given as two 600 mg tablets once daily. As noted above, a second drug this class, EVG, is approved for use as first-line therapy as part of the fixed-dose combination pill of TDF/FTC/COBI/EVG and more recently TAF/FTC/COBI/EVG as a stand-alone drug for use in treatment-experienced patients combining it with a ritonavir-boosted PI. This drug is well tolerated and given as one pill per day, but unlike RAL it does need to be taken with food and it has interactions with other drugs since it must be used with RTV or COBI, so it must be used with caution in those on multiple medications. Another InSTI, DTG is currently recommended for those starting therapy for the first time with either TDF/FTC or ABC/3TC and is available as a fixed-dose combination of ABC/3TC/DTG that can be given as a single pill per day. This drug has a limited number of drug-drug interactions and is generally well tolerated with resistance rarely emerging in those experience virologic failure. Another InSTI in advanced stages of development is called bictegravir (BIC) that has few drug-drug interactions, is potent, well-tolerated, and can be given with or without food. It is expected to be approved as a single-tablet regimen as BIC/FTC/TAF.
Treatment recommendations for children are somewhat different from those for adults. The World Health Organization recommends treating all children less than 5 years of age; children above 5 are treated like adults. The United States guidelines recommend treating all children less than 12 months of age and all those with HIV RNA counts greater than 100,000 copies/mL between one year and five years of age.
There are many drugs currently in development that may simplify therapy and provide important options for those who have developed extensive drug resistance. Drugs that show promise in early clinical trials are often made available by the manufacturer to certain individuals with approval of the FDA. In particular, these drugs are used in individuals who are no longer responding or able to tolerate currently available agents. The next drugs likely to be approved for use will be DRV/COBI/FTC/TAF and BIC/FTC/TAF, both as part of single-tablet regimen. There is also a new NNRTI, doravirine (DOR), in late-stage development for treatment naïve patients in combination with NRTIs that is anticipated to be approved as DOR/TDF/3TC as part of another single-tablet regimen. Novel treatment strategies are also being pursued in the form of a long-acting injectable formulation or RPV in development along with a long-acting new InSTI called cabotegravir (CAB). An early stage study showed that the combination of short-acting RPV and CAB was able to maintain virologic suppression in those with suppressed viral load. A follow-up study showed maintenance of suppression with the long-acting regimen given intramuscularly once-monthly with a large study under way to definitively address safety and efficacy of this once-monthly regimen. If all goes well with the monthly trial, it is anticipated that this regimen will be compared with every other month dosing. Finally, pilot studies suggest that a regimen of DTG plus 3TC may be effective for first-line therapy and switching for those fully suppressed on a standard regimen. Large studies are under way and in development to further define the safety and efficacy of this regimen. Other drugs in earlier stages of development would include new agents in new classes that either block viral maturation of attachment to the cell.

A person gets HIV when an infected person’s body fluids (blood, semen, fluids from the vagina or breast milk) enter his or her bloodstream. The virus can enter the blood through linings in the mouth, anus, or sex organs (the penis and vagina), or through broken skin.
Once HIV is in the immune system, it multiplies inside the CD4 cells, disabling and killing them in the course of the infection, and thus interfering with their normal function. The immune system gradually deteriorates until it reaches a point where it can no longer fight off any infection.
After generic drug manufacturers, such as Cipla in India, began producing discounted, generic forms of HIV medicines for developing countries, several major pharmaceutical manufacturers agreed to further reduce drug prices.

But P appears to have crossed over from a gorilla; it was discovered only last year, and in only one woman, who was from Cameroon, where lowland gorillas are hunted for meat.
The next year, two research teams—one led by Luc Montagnier and Françoise Barré-Sinoussi, of the Pasteur Institute, in Paris, the other by Robert Gallo, at the National Cancer Institute, in Maryland—published papers in Science that described a new retrovirus in the lymph nodes and blood cells of AIDS patients. A retrovirus has a pernicious way of reproducing: it permanently inserts a DNA copy of its genome into the nucleus of a host cell, hijacking the cell’s machinery for its own purposes. When the retrovirus mutates, which it often does, its spawn becomes difficult for the body or a vaccine to target and chase out. Retroviral diseases were widely believed to be incurable. In May of 1986, after much dispute about credit for the discovery (the French finally won the Nobel, in 2008), an international committee of scientists agreed on the name H.I.V., or human immunodeficiency virus. By the end of that year, about twenty-five thousand of the nearly twenty-nine thousand Americans with reported AIDS diagnoses had died.
Treatment for immunodeficiency disorders commonly includes antibiotics and immunoglobulin therapy. Other antiviral drugs, amantadine and acyclovir, or a drug called interferon are used for treatment of the viral infections caused by immunodeficiency disorders.

Because live-virus vaccines are potentially dangerous for patients with severe immunosuppression, expert opinion should be sought when dealing with patients at risk of primary varicella; recommendations vary (see Human Immunodeficiency Virus (HIV) Infection in Infants and Children : Vaccination and Considerations for Use of Live Vaccines in Children With HIV Infection).
If people at low risk have a negative test result, the screening test is not repeated unless their risk status changes. If people at the highest risk have a negative test result (especially if they are sexually active, have several partners, or do not practice safe sex), testing should be repeated every 6 to 12 months.
Certain students with AIDS may assert their right to public education under the Education for All Handicapped Children Act of 1975 (EAHCA), but the law is only relevant in cases involving special education programs. More commonly, students’ rights are protected by the Rehabilitation Act. Perhaps the most important case in this area is Thomas v. Atascadero Unified School District, 662 F. Supp. 376 (C.D. Cal.1986), which illustrates how far such protections go. Thomas involved an elementary school student with AIDS who had bitten another youngster in a fight. Based on careful review of medical evidence, the U.S. District Court for the Central District of California concluded that biting was not proved to transmit AIDS, and it ordered the school district to readmit the girl. Similarly, schools that excluded teachers with AIDS have been successfully sued on the ground that those teachers pose no threat to their students or others and that their right to work is protected by the Rehabilitation Act, as in Chalk.
On the 15th Feb 2012, i lost a dear friend to the dreadful Illness called HIV. I strongly advise everyone, to use Protection when having Sex. Yes, my friend liked Men, and he has paid the price for his Sexual habit. He was only 34 years old, and very clever, but he didn’t think about taking precautions against HIV or AIDS. This information on this page by the MNT you are reading is very important to take in, and be guided by.
