The infections that occur with AIDS are called opportunistic infections because they take advantage of the opportunity to infect a weakened host. A person diagnosed with AIDS may need to be on antibiotic prophylaxis to prevent certain opportunistic infections from occurring. The infections include (but are not limited to) the following:
If the source’s virus is known or suspected to be resistant to≥ 1 drug, an expert in antiretroviral therapy and HIV transmission should be consulted. However, clinicians should not delay PEP pending expert consultation or drug susceptibility testing. Also, clinicians should provide immediate evaluation and face-to-face counseling and not delay follow-up care.

If you believe you have been exposed to HIV, seek medical attention right away. DO NOT delay. Starting antiviral medicines right after the exposure (up to 3 days after) can reduce the chance that you will be infected. This is called post-exposure prophylaxis (PEP). It has been used to prevent transmission in health care workers injured by needlesticks.
Women exposed to HIV infection through heterosexual contact are the most rapidly growing risk group in the United States. The percentage of AIDS cases diagnosed in American women has risen from 7% in 1985 to about 25% in 2006. According to the CDC, in 2006 approximately 278,400 women in the United States were living with HIV/AIDS. The rate was highest among black women and lowest among white women. About 75% of these women contracted HIV through high-risk heterosexual activity; almost all of the remainder acquired the infection through needle sharing.
An alternative view holds that unsafe medical practices in Africa after World War II, such as unsterile reuse of single use syringes during mass vaccination, antibiotic and anti-malaria treatment campaigns, were the initial vector that allowed the virus to adapt to humans and spread.
People who have been exposed to HIV from a blood splash, needlestick, or sexual contact may reduce the chance of infection by taking antiretroviral drugs for 4 weeks. These drugs are more when they are started as soon as possible after the exposure. Taking three or more drugs is currently recommended.
Choice of initial and/or second-line therapy for HIV-2 has not yet been defined. HIV-2 appears to be resistant to NNRTIs intrinsically, but may be sensitive to NRTIs, though the mechanism is poorly understood. Protease inhibitors have shown variable effect, while integrase inhibitors are also being evaluated. Combination regimens of the above listed therapies are being looked into as well, also showing variable effect depending on the types of therapies combined. While the mechanisms are not clearly understood for HIV-1 and HIV-2, it is known that they use different pathways and patterns, making the algorithms used to evaluate HIV-1 resistance-associated mutations irrelevant to HIV-2.
Getting the right screening test at the right time is one of the most important things a man can do for his health. Learn at what age men should be screened for prostate cancer, high blood pressure, cholesterol and other health risks.
Risk of transmission increases in the presence of many sexually transmitted infections and genital ulcers. Genital ulcers appear to increase the risk approximately fivefold. Other sexually transmitted infections, such as gonorrhea, chlamydia, trichomoniasis, and bacterial vaginosis, are associated with somewhat smaller increases in risk of transmission.
During successful treatment, the viral load decreases to very low or undetectable levels (less than about 20 to 40 copies per microliter of blood). However, inactive (latent) HIV is still present within cells, and if treatment is stopped, HIV starts replicating and the viral load increases.

Toxoplasmosis. This potentially deadly infection is caused by Toxoplasma gondii, a parasite spread primarily by cats. Infected cats pass the parasites in their stools, which may then spread to other animals and humans. Seizures occur when it spreads to the brain.
Counseling for pregnant women:Mother-to-child transmission has been virtually eliminated by HIV testing, treatment with ART, and, in developed countries, use of breast milk substitutes. If pregnant women test positive for HIV, risk of mother-to-child transmission should be explained. Pregnant women who do not accept immediate treatment for their HIV infection should be encouraged to accept therapy to protect the unborn baby, typically beginning at about 14 wk gestation. Combination therapy is typically used because it is more effective than monotherapy and less likely to result in drug resistance. Some drugs can be toxic to the fetus or woman and should be avoided. If women meet criteria for ART, they should begin a regimen tailored to their history and stage of pregnancy and continue it throughout pregnancy. Cesarean delivery can also reduce risk of transmission. Regardless of the antepartum regimen used or mode of delivery, all HIV-infected women should be given IV zidovudine during labor, and after birth, neonates should be given oral zidovudine, which is continued for 6 wk after delivery (see also Prevention of Perinatal Transmission). Some women choose to terminate their pregnancy because HIV can be transmitted in utero to the fetus or for other reasons.
HIV is probably directly responsible for a substantial loss of weight (AIDS wasting) in some people. Wasting in people with AIDS may also be caused by a series of infections or by an untreated, persistent digestive tract infection.
The basic subunit of any living organism; the simplest unit capable of independent life. Although there are some single-celled organisms, such as bacteria, most organisms consist of many cells that are specialized for particular functions.
These patients of Sturdevant’s are the faces of one of America’s most troubling public-health crises. Thanks to the success of lifesaving antiretroviral medication pioneered 20 years ago and years of research and education, most H.I.V.-positive people today can lead long, healthy lives. In cities like New York and San Francisco, once ground zero for the AIDS epidemic, the virus is no longer a death sentence, and rates of infection have plummeted. In fact, over the past several years, public-health officials have championed the idea that an AIDS-free generation could be within reach — even without a vaccine. But in certain pockets of the country, unknown to most Americans, H.I.V. is still ravaging communities at staggering rates.
Marfan’s syndrome familial, autosomal-dominant, congenital changes in mesodermal and ectodermal tissues; characterized variably by musculoskeletal changes (e.g. increased height, excessive limb length, arachnodactyly; generalized tissue laxity and joint hypermobility), visual effects, and cardiovascular effects (e.g. aortic aneurysm)
HIV, or human immunodeficiency virus, attacks the immune system by destroying white blood cells, which are vital to fighting infection. Once enough of these cells have been destroyed and the person has another “opportunistic” infection like pneumonia or tuberculosis, the diagnosis moves to the final stage of the infection, called AIDS.
People with HIV/AIDS often develop prolonged diarrhoea which are sometimes not caused by infections. This is more so in the sub‐Saharan Africa where drugs for controlling HIV itself i.e. antiretroviral drugs (ARV) may not be widely available or affordable. prolonged diarrhoea often results in prolonged illness and death due to loss of fluids, if not treated effectively and on time. Antimotility drugs and adsorbents are readily available and are used to try to control this condition while efforts are made to receive ARVs. We did not find enough evidence to support or refute their use in controlling this condition.
HIV is a retrovirus that causes AIDS. HIV attacks the immune system. This system consists of cells and organs that protect the body against diseases like infections and cancer. HIV attacks the immune system through special types of white blood cell known as CD4 cells. CD4 cells play an important role in orchestrating and controlling the functions of the whole immune system.
