[Cat scratch disease caused by Bartonella henselae].
Bartonella henselae is an etiologic agent of cat-scratch disease and, in immunocompromised patients, of bacillary angiomatosis and other severe syndromes. Cat-scratch disease usually presents as lymphadenopathy, which resolves spontaneously within 2-4 months. The utility of antibiotic therapy remains controversial. In Tyrol four cases of human cat-scratch disease were diagnosed in children in 1994, yielding a prevalence of 0.7/100,000 per year. A 3-year-old boy had lymphadenitis coli since one year despite antituberculosis therapy which was initiated because of the histopathological picture and a positive tuberculin reaction (despite negative mycobacteria-cultures and -PCR). Two girls, age 9 and 13 years, had lymphadenitis at upper or lower extremities after cat-scratches from kittens. A 13-year-old boy presented with febrile illness and right hip pain, computer tomography revealed an osteolytic lesion; symptoms subsided within 3 weeks. Diagnosis of cat-scratch disease is based on cat contact, negative studies for other similar diseases, characteristic histopathologic features (if available), and results of an indirect immunofluorescence test (antigen: Houston-1 isolate, ATCC 49882). We believe that the availability of this serological test will increase the number of diagnosed cases of human Bartonella henselae infections.
