Bacillary angiomatosis "cat scratch disease" This is part of a series on Opportunistic Infections ("OIs"). Please note that This Page Is Just A Starting Point: who specializes in treating HIV. Finding The Latest Information: Advances in treating opportunistic infections can happen at any time, so the material on this page may be outdated. Some links in the see also section at the bottom of this page are actually special database links. They may contain information published after this page was written. CD4 Danger Zone CD4+ counts less than 500 cells/mm. NOTE: If you are undergoing treatment that has increased your CD4+ levels, see the important note on Naive T-Cells . There is some evidence that you should use the lowest CD4+ level you ever had when considering your risk for some opportunistic infections. Description Bacillary angiomatosis is an infection caused by bacteria from the genus Rochalimaea.that is characterized by the eruption of cutaneous and subcutaneous nodules. As the number of lesions increases, patients may develop fever, sweats, chills, poor appetite, vomiting and weight loss. If untreated, patients die from complications of the disease. The diagnosis rests on clinical parameters supported by histologic confirmation. Treatment with oral antibiotics for at least 2 weeks is highly effective. [ This infection can cause blood vessels to grow out of control and form tumor-like masses in skin, bone, liver and other organs.

Localization of Mycobacterium avium-intracellulare within a skin lesion of bacillary angiomatosis in a patient with AIDS. Diagn Mol Pathol. 1992 Sep;1(3):212-6. Unique Identifier : AIDSLINE MED/94115766 Sagerman PM; Relman DA; Niroomand F; Niedt GW; Department of Pathology, Memorial Sloan-Kettering Cancer Center,; New York, NY 10021. Abstract: We report a 39-year-old man who had AIDS and who presented with an unusual cutaneous vascular lesion, which was clinically thought to be Kaposi's sarcoma. Histologically, the lesion was characterized by capillary proliferation and a mixed inflammatory infiltrate that included numerous histiocytes. The lesion was found to contain slender intracellular acid-fast bacilli, as well as plump extracellular Warthin-Starry-positive bacilli. The acid-fast bacilli were confirmed to be Mycobacterium avium-intracellulare by subsequent positive blood cultures for this organism. To further investigate the lesion, polymerase chain reaction DNA amplification and sequencing was performed, and the lesion was found to contain DNA sequences identical to those previously established for the agent of bacillary angiomatosis . The lesion is thought to represent a lesion of bacillary angiomatosis with secondary involvement by M. avium-intracellulare. Keywords: National Library of Medicine .

Recognition of the etiologic agents and a new understanding of the fundamental features of the epidemiology and natural history of modern day Bartonella (formerly Rochalimaea)-associated diseases culminate a multipartite story that combines clinical medicine, traditional microbiology, and novel technological approaches to solve a long-standing enigma. The quest for the etiologic agent of cat-scratch disease (CSD) has frequently been described as a mystery . Indeed, the search has many qualities of a mystery novel; the pursuit has spanned several decades and recently taken several unexpected turns. During this period of important discovery, major microbial suspects have undergone name changes, novel microbial culprits have been introduced, new groups of affected patients have been recognized, and yet significant questions remain to be answered. Scientific and medical interest has been high; approximately 900 publications have dealt with CSD since the first good clinical description of the disease in 1950

This condition is characterized by a proliferation of blood vessels in the skin and internal organs. Skin lesions are nodular and red or purplish in color, and may eventually ulcerate and drain. Diagnosis is made by biopsy, and treatment consists of a prolonged course of an oral macrolide antibiotic such as erythromycin or azithromycin.

Site map Search: Home Bacterial Bacillary angiomatosis Bacillary angiomatosis is a systemic illness characterised by lesions similar to those of Kaposi sarcoma in the skin, mucosal surfaces, liver, spleen and other organs. It is caused by bacterial infection with Bartonella quintana and Bartonella henselae (cause of catscratch disease ). The disease is only rarely seen in healthy immunocompetent people. It mostly affects immunocompromised patients, particularly those with AIDS or HIV How do you get bacillary angiomatosis? Bacillary angiomatosis is caused equally by Bartonella quintana and Bartonella henselae . It is usually a result of exposure to flea-infested cats with Bartonella henselae and the human body louse for Bartonella quintana (cause of trench fever in soldiers during World War I). Nowadays, the disease occurs mainly in AIDS patients. It may also be a complication of catscratch disease in immunocompetent patients. What are the signs and symptoms of bacillary angiomatosis?
