BACILLARY ANGIOMATOSIS SYMPTOMS |

|
Scientists have recently isolated two
varieties of the Bartonella bacteria as the cause of bacillary
angiomatosis: Bartonella (formerly Rochalimaea quintana) and B.
henselae (cause of cat-scratch disease). B. quintana infection is known popularly as trench fever, and is the infection associated with body lice that sickened European troops during World War I. Lice carry the bacteria, and can transmit the infection to humans. The incidence of trench fever was believed to have faded away with the end of World War I. It was not diagnosed in the United States until 1992, when 10 cases were reported among homeless Seattle men. The related bacteria B. henselae was first identified several years ago as the cause of cat-scratch fever. It also can lead to bacillary angiomatosis in AIDS patients. Bacillary angiomatosis caused by this bacteria is transmitted to AIDS patients from cat fleas. These two different types of bacteria both cause bacillary angiomatosis, a disease which is characterized by wildly proliferating blood vessels that form tumor-like masses in the skin and organs. The nodules that appear in bacillary angiomatosis are firm and don't turn white when pressed. The lesions can occur anywhere on the body, in numbers ranging from one to 100. They are rarely found on palms of the hands, soles of the feet, or in the mouth. As the number of lesions increase, the patient may develop a high fever, sweats, chills, poor appetite, vomiting and weight loss. If untreated, the patient may die. In addition to the basic disease process, the two different types of bacteria cause some slightly different symptoms. Patients infected with B. henselae also experience blood-filled cysts within the liver and abnormal liver function, whereas B. quintana patients may have tumor growths in the bone. |
