    ABSTRACT: Bartonella henselae, the etiologic agent of cat-scratch disease, causes a well-defined, self-limited syndrome of fever and regional lymphadenopathy in immunocompetent hosts. In immunocompromised hosts, however, B. henselae can cause severe disseminated disease and pathologic vasoproliferation known as bacillary angiomatosis (BA) or bacillary peliosis. BA was first recognized in patients infected with human immunodeficiency virus. It has become more frequently recognized in solid organ transplant (SOT) recipients, but reports of pediatric cases remain rare. Our review of the literature revealed only one previously reported case of BA in a pediatric SOT recipient. We herein present 2 pediatric cases, one of which is the first reported case of BA in a pediatric cardiac transplant recipient, to our knowledge. In addition, we review and summarize the literature pertaining to all cases of B. henselae-mediated disease in SOT recipients.

    ABSTRACT: In this paper, we report an investigation on cat-scratch disease (CSD) in Northern Italy. Seventy-four cases of CSD were diagnosed at the San Matteo hospital, Pavia, during the period 2005-2010. Of these 74 patients, 18 (24.3 %) reported atypical clinical manifestations such as ocular papillitis, maculopapular eruptions, vertebral infection, pulmonary infiltrates, and granulomatous hepatitis. Contact with cats was documented for 61 patients (82.4 %), while cat-related trauma was reported for 49 patients (66.2 %). We subsequently investigated the presence of Bartonella infection in cats belonging to the above patients and in other domestic and stray cats from three provinces of Northern Italy. Among the 27 domestic cats tested, nine of the 11 belonging to the CSD patients and two of the remaining 16 were infected by B. henselae (81.8 % vs. 12.5 %). Out of over 1,300 stray cats examined, 23.1 % were seropositive for B. henselae; after culturing and genotyping, 17 % were found to be infected by B. henselae (15.5 %) or B. clarridgeiae (1.5 %).

    ABSTRACT: Cat scratch disease has been reported very rarely in cardiac transplant recipients. In a review of 1073 episodes of infection in 620 heart transplant patients over a 16 year period, only one case of infection secondary to Bartonella henselae was documented. Another case of hepatosplenic bacillary angiomatosis from B. henselae was reported 2 decades ago in a heart transplant recipient who had presented with fevers of unknown origin. Although the typical clinical manifestation is that of a skin lesion accompanied with lymphadenopathy, cat scratch disease may present with persistent fevers without a clinically overt infective focus in immunosuppressed individuals. Moreover, more than one disease process may coexist in immunocompromised hosts. While the lymphadenopathy in our patient was secondary to Cat scratch disease, interestingly, the adjacent skin lesion that was thought to represent unhealed site of inoculation of Bartonella was diagnosed as squamous cell carcinoma.
