Angiomatose bacilar pós-transplante renal: apresentação de um caso / Bacillary angiomatosis after kidney transplantation

A bartonela causa a Doença da arranhadura do gato, mas em imunossuprimidos pode levar à doença sistêmica, denominada angiomatose bacilar.Descrição do caso: Masculino, 15 anos, transplantado há 3 anos, em uso de FK, MMF e prednisona com função renal preservada. Refere tumoraçãoavermelhada e dolorosa na região mandibular esquerda há 30 dias, com febre elevada há 7 dias. Esta em regular estado geral, descorado, 39ºC, commassa submandibular de 4cm de diâmetro, consistência carnosa com vesículas na superfície e hepato-esplenomegalia. Bx da massa compatível com Angiomatose Bacilar. Evoluiu bem com Cloranfenicol e Eritromicina. Apresentou elevação da creatinina sérica, sendo feita hipótese de rejeição e realizadopulso de metilprednisolona com normalização da função renal. Conclusões: Como a soroprevalência de Bartonela, em gatos, é elevada em nosso meio, deve-se estar alerta para seu diagnóstico. Pacientes imunossuprimidos podem apresentar formas sistêmicas graves de infecções comuns que, pelararidade, podem ser diagnosticadas tardiamente e carrear maior morbidade.

Bartonela sp causes cat scratch disease but in immunosuppressed hosts it can be associated with a systemic disease named bacillary angiomatosis.Description of case: A 15-year old boy with a successful kidney transplant for 3 years had been treated with FK, MMF and prednisone. He reported ared and painful mass in the left submandibular area for 30 days, and high fever for the last 7 days. He looked sick, pale and had a submandibular mass of 4cm in diameter with vesicles in its surface and hepatosplenomegaly. Biopsy of the mass was suggestive of bacillary angiomatosis. He was treated withchloramphenicol and erythromycin and had a favorable course. An increase of creatinine, interpreted as rejection, was successfully managed with a pulseof methylprednisolone. Conclusions: As the prevalence of bartonelosis in cats is elevated in our country, physicians should be aware of that diagnosticpossibility. Immunocompromised hosts may present rare systemic forms of common diseases that can be diagnosed late and produce sequels.

Bacillary angiomatosis: description of 13 cases reported in five reference centers for AIDS treatment in Rio de Janeiro, Brazil

The aim of this case series was to describe the clinical, laboratory and epidemiological characteristics and the presentation of bacillary angiomatosis cases (and/or parenchymal bacillary peliosis) that were identified in five public hospitals of Rio de Janeiro state between 1990 and 1997; these cases were compared with those previously described in the medical literature. Thirteen case-patients were enrolled in the study; the median age was 39 years and all patients were male. All patients were human immunodeficiency virus type 1 (HIV-1) infected and they had previous or concomitant HIV-associated opportunistic infections or malignancies diagnosed at the time bacillary angiomatosis was diagnosed. Median T4 helper lymphocyte counts of patients was 96 cells per mmÝ. Cutaneous involvement was the most common clinical manifestation of bacillary angiomatosis in this study. Clinical remission following appropriate treatment was more common in our case series than that reported in the medical literature, while the incidence of relapse was similar. The frequency of bacillary angiomatosis in HIV patients calculated from two of the hospitals included in our study was 1.42 cases per 1000 patients, similar to the frequencies reported in the medical literature. Bacillary angiomatosis is an unusual opportunistic pathogen in our setting

Bacillary angiomatosis and mycobacterium infection coexisting in a cutaneous lesion in a patient with AIDS.

Bacillary angiomatosis is a recently recognized bacterial infectious disease. It mainly affects patients with acquired immunodeficiency syndrome. The presence of coexistent infections of more than one pathologic process in skin lesions in patients with AIDS has been demonstrated. We report a patient with AIDS in whom both bacillary angiomatosis and mycobacterium infection were documented within the same cutaneous lesion.
