The training and qualifications of providers treating patients with HIV/AIDS is very important. But equally important is an understanding of the impact of numbers of patients treated by providers on key medical outcomes (e.g. viral load measures, mortality, the receipt of anti‐retroviral medications, opportunistic infection (OI) prophylaxis as well as economic outcomes such as health care utilization or patient costs) in the care of persons living with HIV/AIDS. This systematic review examined studies from 1980‐2009 that identified both provider experience/qualifications as well as a volumes indicator (number of HIV/AIDS patients). Only four studies met the inclusion criteria for the final review. Given the varied methods of each study, a meta‐analysis was not possible.
HIV RNA tests can confirm positive results of an antibody test or detect evidence of HIV infection when antibody test results are negative. HIV RNA tests often use techniques to produce many copies of an organism’s genetic material (called nucleic acid amplification). These tests can detect very small amounts of HIV RNA in blood and are very accurate.
There are many drugs currently in development 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.
There are currently nine approved PIs that all have distinct toxicities. The most common side effects associated with these drugs are nausea and diarrhea, which occur more often with some PIs than others. For example, diarrhea is more common with NFV than other PIs but can occur with any and all drugs in this class. Many of the drugs in this class also increase blood lipid levels, some more than others with ATV and DRV appearing to have less effect on lipids than other drugs in the class. Other unique toxicities associated with various PIs are kidney stones, kidney damage, and increases in blood bilirubin levels and potentially jaundice with IDV and ATV. Some of these drugs also have been associated with elevations in blood sugar levels and bleeding in hemophiliacs. Finally, little is known regarding the role these drugs may play in the development of lipodystrophy. There is also some data suggesting that LPV/RTV and DRV may be associated with an increased risk of cardiovascular events.
Doctors will use a wide variety of tests to diagnose the presence of opportunistic infections, cancers, or other disease conditions in AIDS patients. Tissue biopsies, samples of cerebrospinal fluid, and sophisticated imaging techniques, such as magnetic resonance imaging (MRI) and computed tomography scans (CT) are used to diagnose AIDS-related cancers, some opportunistic infections, damage to the central nervous system, and wasting of the muscles. Urine and stool samples are used to diagnose infections caused by parasites. AIDS patients are also given blood tests for syphilis and other sexually transmitted diseases.
MVC is typically dosed at either 300 mg or 150 mg twice daily, depending upon what other drugs it is given with. If the patient is taking any RTV, then they would usually receive the 150 mg dose. If RTV is not being used as part of the regimen, they would generally receive the 300 mg dose and sometimes even higher if it is being used with drugs like ETR. HIV providers are aware that whenever using any anti-HIV medications attention must be given to possible drug interactions.
By the end of 1990, over 307,000 AIDS cases had been officially reported with the actual number estimated to be closer to a million. Between 8-10 million people were thought to be living with HIV worldwide.50
The election of Barack Obama brought renewed attention to the domestic epidemic and loosened the conservative grip on the federal government’s prevention and research agenda. At the first post-Bush national H.I.V.-prevention conference in 2009, Christopher Bates, then the director of H.I.V./AIDS policy for Health and Human Services and interim executive director of the Presidential Advisory Council on H.I.V./AIDS, kicked off the event in Atlanta by jumping onstage with duct tape on his mouth, ripping it off and shouting, “Finally, I can speak!” On World AIDS Day in 2011, Obama directly addressed the H.I.V. crisis among gay black men in a speech at George Washington University: “When new infections among young black gay men increase by nearly 50 percent in three years, we need to do more to show them that their lives matter.”
A few exceptional patients can control their HIV strain without treatment; they maintain normal CD4 counts and very low blood levels of HIV (long-term nonprogressors) or normal CD4 counts and undetectable blood levels of HIV (elite controllers). These patients may not require ART, but studies to determine whether treating them is helpful have not been done and would be difficult because there are few of these patients and they would likely do well not taking ART for long periods.
AIDS is an infectious disorder that suppresses the normal function of the immune system. It is caused by the human immunodeficiency virus (HIV), which destroys the body’s ability to fight infections. Specific cells of the immune system that are responsible for the proper response to infections (T cells) are destroyed by this virus. Characteristically a person infected with HIV initially experiences no symptoms for a variable period of time. This may be followed by the development of persistent generalized swelling of the lymph nodes (AIDS-related lymphadenopathy). Eventually most patients infected with HIV experience a syndrome of symptoms that includes excessive fatigue, weight loss, and/or skin rashes.

Young adults tend to be at higher risk of acquiring HIV, typically through high-risk activities such as unprotected sexual intercourse or intravenous drug use. In 2009 in the US, the largest percentage (15% of all diagnoses) and the highest rate (36.9 per 100,000 population) were in persons aged 20–24 years. 
If doctors suspect exposure to HIV infection, they do a screening test to detect antibodies to HIV. (Antibodies are proteins produced by the immune system to help defend the body against a particular attack, including that by HIV.) In addition, doctors recommend that all adults and adolescents, particularly pregnant women, have a screening test regardless of what their risk appears to be. Anyone who is concerned about being infected with HIV can request to be tested. Such testing is confidential.

Most individuals develop antibodies to HIV within 28 days of infection and therefore antibodies may not be detectable early, during the so-called window period. This early period of infection represents the time of greatest infectivity; however HIV transmission can occur during all stages of the infection.
AIDS is one of the most devastating worldwide public health problems in recent history. The United States Centers for Disease Control and Prevention (CDC) estimated that in 2006 944,000 people in the United States had been diagnosed with AIDS since the disease was identified in 1981. In 2006, an additional 1-1.2 million Americans were diagnosed as infected with HIV but not yet showing symptoms (HIV positive). However, in early 2009, the CDC issued a statement that they now thought that earlier the HIV-positive estimates were too low, as many more people than were originally estimated are living with unreported or undiagnosed HIV infection.
