AIDS

According to National Institute of Health (NIH (2006 , Acquired Immunodeficiency Syndrome (AIDS ) is caused by Human Immunodeficiency Virus (HIV ) by gradually destroying CD4 T cells (also called T-helper cells , which play a significant role in the immune response system In a healthy subject the CD4 T cells range between 800 to 1 ,200 cells /mm3 but when this count falls below 200 cells /mm3 , the individual is most vulnerable to opportunistic infections ‘ and cancers typical of AIDS

From the above it is evident that body has its own mechanism to [banner_entry_middle]

prevent infections i .e , immune response system comprising of CD4 T cells which are actually attacked by HIV systematically destroying the CD4 T cells These cells are active in fighting back infections attacking the body thus once their count falls abnormally the body is vulnerable to the so called opportunistic infections ‘ which are typical of AIDS

Grant and Cock (2001 ) stated that general symptoms in the early stages include loss of weight , fever , sweating during nights , diarrhea and frequent skin diss especially of varicella zoster , fungal infections and pruriginous dermatitis leading to itchy rashes resulting into ulcerations and healing with pigmented macules

Cryptococcal meningitis is infection of the brain and is due to spread of fungus from lungs to the brain through blood circulation . People who have defects in their cell-mediated immunity such those suffering from AIDS , are susceptible to disseminated cryptococcosis . Cryptococcal meningitis is fatal . The fungus infects the nervous system causing inflammation of the membranes covering the brain and spinal cord

The more frequent probable causes of HIV related diseases include cerebral toxoplasmosis and cryptococcal meningitis , cerebral toxoplasmosis most often presents as a space occupying lesion of the brain , and cryptococcosis as chronic meningitis ‘ thus brain gets effected in particular and nervous system in general

One of the important opportunistic infections ‘ includes tuberculosis and may be detected at any stage in the course of immunodeficiency Pulmonary tuberculosis is similar to non-HIV infected subjects in the initial stages of HIV infection , but the advanced stages of immunodeficiency exhibit disseminated and multibacillary nature of tuberculosis ‘ thus causing extensive damage to lungs in general and pulmonary system in particular

Pneumonia is an acute or chronic inflammation of lungs caused… [banner_entry_footer]
