is usually marked by a decrease of the number of cells CD4, defence cells, followed by an increase in the frequency of the number of opportunistic infections and cancer. In the terminal stage of AIDS doctors control the number and proportion of CD4 T lymphocytes in the blood of the infected in order to assess the progression of the disease and the effectiveness of the various drugs.
When lymphocyte count falls below the 200 cells/cubic millimeter, a high risk of developing the aforementioned opportunistic infections, whose infectious microorganisms can be the following:
> fungi, infection by yeast in the mouth (candidiasis or thrush) and meningitis cryptococcal.
> Protozoa, parasitic diseases of which the most common is pneumonia. Approximately of 70 to 80% of sufferers her lifelong prior to perish. This microorganism is the immediate cause of death of almost 20 per cent of those infected.Other diseases in this group include toxoplasmosis, amebiasis and Cryptosporidiosis.
≫ Mycobacteria, such as those that cause tuberculosis in 40% of the sick.
≫ bacteria, that is, is more likely to develop bacterial lesions of the skin and digestive tract.
> Virus, the virus of the herpes simplex, varicella zoster virus and Epstein-Barr virus, Cytomegalovirus, before which is particularly vulnerable during this stage. Other viruses can cause progressive destruction of brain tissue and stem, the brainstem and the cerebellum (multifocal leukoencephalopathy), which is considered a defining disease of AIDS.
On the other hand, the dementia complex syndrome is a late complication of the disease, and is characterized by a loss of the ability of reasoning, memory loss, inability to concentrate, apathy, loss of initiative and instability or weak to walk. In some cases, also seizures.
