It is to find out the prevalence of celiac disease and to see whether it had any long-term health hazards if left unnoticed or diagnosed late a research team was formed under the leadership of Dr. Joseph Murray at Mayo Clinic. This team of researchers tested some blood samples gathered at Warren AFB (Air Force Base) in Wyoming during the time span of 1948 and 1954 for the presence of the antibody that a person with CD produce in reaction with the protein gluten.

They also compared this result with the results of the blood test collected form the Olmsted Country at Minnesota. The comparison study revealed surprising results that the young people of today are almost 4.5 times more likely to get affected by CD that the young people of 1950’s. Speaking about the results Dr. Murray said, CD is unusual but is no more a rare syndrome. He also added that celiac disease has become more common that it affects one in a hundred Americans.

This study also reported that people who were unaware of the fact that they have CD are 4 times more likely to die than people who were CD-free during its 45 years of research. Dr. Murray also confirmed this fact when he said undiagnosed CD may prove vital that it may have a serious impact on one’s survival.

When a person with this disease eats some food containing gluten, his/her immune system attacks the small intestine and destroys the intestine villi and also stops the absorption of vital nutrients into the body. Some of the symptoms of this disorder include abdominal discomfort, diarrhea, sudden weight loss, loss of teeth, anemia, infertility and even osteoporosis.

Most of us are aware of the criminal behind this disease, the human immunodeficiency virus, commonly known as HIV. This is a kind of retrovirus that targets a particular kind of cell in the immune system for its growth and expansion.This virus thus multiplies by killing a vast number of CD4+ cells present in our immune system. These cells are also known as the T-cells and are necessary elements of the immune system that helps our body to fight against infections.

Thus a person tested positive with HIV begins to lose his/her immune system gradually as the virus eats and damages more CD4+ cells in the immune system. When this infection prolongs for a longer period, the person is said to have developed AIDS. But it can be many years before HIV has completely damaged the immune system for the disease to develop. There are some specific symptoms for AIDS that doctors have identified through these years. These are known as AIDS-related symptoms or opportunistic infection though it is possible for someone to develop AIDS without these infections.

HIV is normally present in the genital secretions and the blood of the person who is infected with this virus. The virus spreads when these genital secretions come in contact with the some tissues lining the vagina, mouth and the anal area.

Tissues lining around the eyes are also affected when these secretions come in contact with them. Break in the skin like a cut or a puncture by needle also causes the virus to spread from one person to another. The common ways in HIV is spread include sexual intercourse, sharing of used needles and by transmission from a infected mother to their children.
