Although there is still controversy as to the causative agent, AIDS – acquired immunodeficiency syndrome – is commonly thought to be caused by the human immunodeficiency virus (HIV). By killing or damaging cells of the body's immune system, HIV progressively destroys the body's ability to fight infections and certain cancers.
AIDS was first reported in the United States in 1981 and has since become a major worldwide epidemic. When the first AIDS cases were recognized, few would have thought that so many years would pass without a cure being discovered.
By 2001, more than 750,000 cases of AIDS had been reported in the United States and as many as 1,000,000 Americans were thought to be infected with HIV – an infection rate of about 0.4%. Growing most rapidly among minority populations, it is a leading killer of African-American males. The rates of infection are very high in some southern African countries, with the situation in Botswana being described as shocking – by 2001 some 36% of the adult population was infected. South Africa came second in that region with a 20% rate.
HIV is spread most commonly by having unprotected sex with an infected partner, contact with infected blood or being born to an HIV-infected mother. Approximately one-quarter to one-third of all untreated pregnant women infected with HIV will pass the infection to their babies. HIV also can also be spread to babies through the breast milk of infected mothers.
Studies of families of HIV-infected people have shown clearly that HIV is not spread through casual contact such as the sharing of food utensils, towels and bedding, swimming pools, telephones, or toilet seats. HIV is not spread by biting insects such as mosquitoes or bedbugs. Scientists also have found no evidence that HIV is spread through sweat, tears, urine, or feces.
Many people do not have any symptoms when they first become infected with HIV. Some people, however, have a flu-like illness within a month or two of being exposed to the virus. This illness may include fever, headache, tiredness or enlarged lymph nodes. These symptoms are often mistaken for those of another viral infection. During this period, people are very infectious and HIV is present in large quantities in genital fluids.
More persistent or severe symptoms may not surface for years after infection in adults, or for two years in children born with HIV infection. This period of "asymptomatic" infection is highly individual. Some people may begin to have symptoms within a few months, while others may be symptom-free for more than 10 years.
Even during the asymptomatic period, the virus is multiplying, infecting, and killing cells of the immune system, especially T4 cells (CD4+). At the beginning of its life in the human body, the virus disables or destroys these cells without causing symptoms.
The term AIDS applies to the most advanced stages of HIV infection. The Center for Disease Control defines AIDS as all HIV-infected people who have fewer than 200 T4 cells per cubic millimeter of blood. Healthy adults usually have 1,000 or more. In addition, the definition includes over 20 clinical conditions that affect people with advanced HIV disease. Most of these conditions are opportunistic infections that generally do not affect healthy people. Amongst people with AIDS, these infections are often severe and sometimes fatal because the immune system is so damaged by the virus that it can no longer fully resist.
Children with AIDS may get the same opportunistic infections as adults. In addition, they also have severe forms of the bacterial infections that all children may get, such as conjunctivitis (pink eye), ear infections or tonsillitis.
During the course of HIV infection, most people experience a gradual decline in the number of T4 cells, although some may have abrupt and dramatic drops in their T4 cell counts. A person with a T4 cell count above 200 may experience some of the early symptoms of HIV disease, while others may have no symptoms even though their T4 cell count is below 200.
The most common clinical presentations in the high-risk groups or ARC patients include: chronic generalized lymphadenopathy, splenomegaly, fever, fatigue, malaise, night sweats, weight loss, anorexia, oral candidiasis, recurrent herpes infections, and diarrhea. Also, a mononucleosis-like syndrome can occur, characterized by prolonged fever, rigors, myalgias, arthralgias, rash, abdominal cramps, and diarrhea, and this is associated with seroconversion for the HIV antibody.
Because early HIV infection often causes no symptoms, a doctor usually diagnoses it by testing a person's blood for the presence of antibodies to HIV. HIV antibodies generally do not reach detectable levels in the blood for one to three months following infection.
People exposed to the virus should get an HIV test as soon as they are likely to develop antibodies to the virus i.e. within 4 weeks to 12 months after possible exposure to the virus. One or two follow-up tests (using different testing methods if possible) should be performed to confirm diagnosis. By detecting it early, people with HIV infection can discuss with their doctor when they should start treatment to help their immune systems combat HIV and help prevent the emergence of opportunistic infections. Early testing also alerts HIV-infected people to avoid high-risk behaviors that could spread the virus to others.
Healthcare providers diagnose HIV infection by using two different types of antibody tests, ELISA and Western Blot. If a person is highly likely to be infected with HIV and yet both tests are negative, the doctor may request additional tests. The person also may be told to repeat antibody testing at a later date, when antibodies to HIV are more likely to have developed.
Polymerase chain reaction (PCR) testing is more expensive and labor-intensive but can detect the virus even in someone only recently infected. Urine testing for HIV antibodies is not as sensitive or specific as blood testing but may be used for someone who does not want blood drawn.
Babies born to mothers infected with HIV may or may not be infected with the virus, but all carry their mothers' antibodies to HIV for several months. If these babies lack symptoms, a doctor cannot make a definitive diagnosis of HIV infection using standard antibody tests until after 15 months of age. By then, babies are unlikely to still carry their mothers' antibodies and will have produced their own, if they are infected. Health care experts are using new technologies to detect HIV itself to more accurately determine HIV infection in infants between ages 3 months.
To effectively deal with the confusion about AIDS, the diagnosis and it's treatment requires personal involvement. It really is important that everyone facing AIDS must educate themselves carefully in order to be prepared for the challenges and comfortable with the decisions that will need to be made. While many alternative therapies have turned out to be less effective than initially thought, there is much that can be done to enhance immune function and keep the infection in check.
Health care for people living with HIV has improved substantially and the outlook is much brighter than in the 1980s and 1990s, with new drugs having been developed and the costs having come down dramatically.
In the early 1980s, life expectancy for an HIV-infected person would have been around 1-2 years. By 1996, the life expectancy of an HIV-infected 20-year-old was 39 years; by 2011, this figure had risen to around 70 years. Someone who is HIV-positive and receives timely diagnosis followed by proper treatment should now be able to have a normal life expectancy.
Some people get a flu-like illness within a month or two after first getting HIV. The flu-like symptoms often go away within a week, and include fever, headache, fatigue (being a lot more tired than usual, and all the time), swollen lymph nodes (glands in the neck and groin).
The depressed cellular immunity seen in HIV infection increases the risk of coccidioidomycosis. Individuals with AIDS are at high risk not only for pulmonary coccidioidomycosis but for the disseminated form and cutaneous form of the disease.
CD4 cells are those cells that are primarily infected with HIV. CD8 cells are those cells that are primarily involved with killing HIV. So as HIV infection progresses, you lose CD4 cells and increase the number of CD8 cells.
Scientists are finding that the status of vaginal flora may significantly affect both the amount and the survival of HIV virus inside the female genital tract. Abnormal vaginal flora – i.e. infection with candida or bacterial vaginosis – corresponded with increased amounts of HIV virus in the cervico-vaginal secretions of women who were HIV-positive. The HIV infection rate among women with bacterial vaginosis is twice as high as it is in those with healthy vaginal flora. Understanding these dynamics can "help shape preventative strategies aimed at reducing both heterosexual and the mother-to-child transmission of HIV", the researchers observed. [BJOG 2001;108: pp.634-641]
An estimated 45% of men with untreated AIDS and 25% of asymptomatic, untreated HIV-infected men experience low testosterone levels. Both men and women may be negatively affected by testosterone deficiency.
HIV or AIDS patients are especially likely to develop hairy leukoplakia. Although modern drugs have reduced its incidence, as many as 25% of HIV-positive people still develop hairy leukoplakia. It can be one of the first signs of HIV infection.
Any condition that attacks or suppresses the body's immune system can cause you to develop mouth ulcers.
In general, diagnosis and treatment endocrine issues in HIV patients is no different from non-HIV patients. However, HIV can cause reactive changes in pituitary and adrenal function, as can many HIV medications.
Fatigue can be one of the most debilitating symptoms experienced by people with HIV disease, as well as one of the most under-reported and under-recognized aspects. The rate of fatigue increases as the disease progresses and women are more likely to experience fatigue than men. HIV-positive men with CD4 cell counts below 500 cells/ml experienced more fatigue than men with CD4 cell counts above 500. However, studies so far have not found a consistent correlation between viral load and fatigue. The fatigue may be due to anemia, depression, the HIV virus, secondary infections, hormone deficiency (testosterone, adrenal exhaustion), malnutrition, poor sleep quality or quantity, inactivity, or drug side-effects.
People with HIV/AIDS are particularly prone to developing various cancers, especially those caused by viruses such as Kaposi's sarcoma, cervical cancer or cancers of the immune system known as lymphomas.
Individuals with muscle-wasting and immune-system related illnesses (such as cancer or AIDS) who may be incapable of manufacturing their own supply of glutamine, may benefit from glutamine supplements taken along with other amino acids.
In one study, 10 patients with AIDS who were given 5 to 10gm per day of an aged garlic extract later had increased levels of natural killer cells, a higher helper:suppressor ratio, and reduced infection rates.
Marijuana is being used to moderate wasting syndrome in AIDS patients. [Grinspoon, L., and Bakaler, J.B. "Marijuana as Medicine." Journal of the American Medical Association 1995; 273(23): pp1875-76.]
During the normal progression of this disease, NK cell activity begins to drop along with that of other immune cells. T4 levels routinely decrease at a rate of about 15% per year. Dr Ghoneum, who has been researching MGN-3 since 1993, reports that T4 levels can be maintained in almost every case of AIDS he has tested, and oftentimes they will even begin to increase. Although the number of patients studied has been limited, all of the patients who have taken MGN-3 reported a noticeable difference in their well-being, and have continued to use the product. Most felt that MGN-3 was instrumental in helping them stabilize their disease.
A German study examined the use of Iscador, a mistletoe extract, in 40 HIV-positive patients with less than 200 T4 cells/ml. Patients injected themselves subcutaneously with 0.01mg to 10mg of Iscador twice per week for eighteen weeks. The only toxicities were transient fever on the day of injection and soreness at the injection site. The researchers of this small, unblinded and unreviewed study reported that 28 of the 36 patients (77%) had increases in T4 levels of greater than 20%. Iscador should only be administered under the supervision of a doctor familiar with its use. [Gorter R, et al. Abstract PO-B28-2167. IX International Conference on AIDS. Berlin. June 1993]
Alginic acid has been shown to inhibit HIV in the test tube. [Béress A, Wassermann O, Bruhn T, et al. A new procedure for the isolation of anti-HIV compounds (polysaccharides and polyphenols) from the marine alga Fucus vesiculosus. J Nat Prod 1993;56: pp478-88.] However, this effect has not been studied in humans.
BHT is a potent inactivator of lipid-enveloped viruses. The viral envelope structure is physically disturbed by BHT, thereby interfering with viral adsorption to host cells. Since the virus generally believed responsible for AIDS contains a lipid envelope, BHT warrants investigation as a potential antiviral agent against the AIDS virus. Published scientific evidence strongly suggests that BHT might help in treating AIDS or ARC and that any risks can be kept small. No one expects BHT to be a cure, but if it can help in the management of AIDS and/or CMV, it would have value now until better treatments become available.
Sugar and corn syrup found in many desserts impair the engulfing power of white blood cells. The worst offenders are found in canned soda, candy bars, pastry and other processed desserts. Even sugars found in fruit juice, when consumed quickly, will have a depressive effect on immune cells.
Lauric acid from coconut oil, coconut milk and fresh or cooked coconut meat, at 24gm daily for adults, may be an effective aid in the destruction of lipid-enveloped viruses such as HIV, HHV-6 (strains A and B), EBV, CMV and herpes. This treatment may be used continuously as viral resistance or immune system adaption is not expected to develop.
Extended fasting should be avoided in AIDS patients, who tend to be malnourished already.
Prednisone must be used cautiously by HIV-positive individuals because it is immunosuppressive and can increase the risk of getting opportunistic infections.
Several studies have shown that testosterone levels are generally lower and that testosterone administration alleviates fatigue and depression in men with HIV/AIDS. In one study, 80% of men reported significant improvements in their energy levels. [General Hospital Psychiatry, July 1998]
