Disseminated aspergillosis in two dogs in Israel

MYCOSES, Issue 2 2006
Y. Bruchim
Summary Aspergillus terreus, normally a soil or plant saprophyte, causes disseminated systemic infection, involving primarily the skeletal and the cardiopulmonary system in humans and dogs.1, 2 We describe two cases of German shepherd dogs that were referred to Koret School of Veterinary Medicine Teaching Hospital with a history of anorexia and weakness. Case 1 suffered from neurological deficits, paraparesis and lumbar pain whereas case 2 suffered from unilateral uveitis and exophthalmus. Both dogs were treated symptomatically, but deteriorated progressively despite therapy and were therefore euthanised. Necropsy revealed disseminated aspergillosis, and numerous organs had multiple, miliary, white-yellow foci. Microscopically, these were identified as granulomas, containing fungal hyphae. Affected tissue included brain, heart, kidneys, spleen, lymph nodes and bones (case 2). Aspergillus terreus was isolated from different organs and from urine culture. We suggest that disseminated aspergillosis should be considered as a differential diagnosis in German shepherd dogs presenting with ocular disease, neurological deficits, spinal column pain, urinary system disorders, and radiographic evidence of skeletal and/or respiratory pathology.

Successful treatment of disseminated aspergillosis with the combination of voriconazole, caspofungin, granulocyte transfusions, and surgery followed by allogeneic blood stem cell transplantation in a patient with primary failure of an autologous stem cell graft

Abstract:, The treatment of disseminated aspergillus infections in neutropenic patients remains a major challenge in spite of several new antifungal drugs. We report the case of a patient with multiple myeloma in prolonged neutropenia after primary failure of an autologous stem cell graft who developed invasive aspergillosis despite voriconazole monotherapy. He responded to a combination of voriconazole and caspofungin, supported by granulocyte transfusions and surgery. A subsequent allogeneic peripheral blood stem cell transplantation did not lead to recurring aspergillus infection. The patient is well and free of clinical disease with respect to the fungal infection and myeloma more than 18 months after the allogeneic transplantation. [source]

Solitary embolic cutaneous aspergillosis in the immunocompromised patient with acute myelogenous leukemia , a propos another case caused by Aspergillus flavus

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2003
Aleksandar L. Krunic MD
A 68-year-old male with acute myelogenous leukemia was admitted for consolidation chemotherapy. The in-hospital course was complicated by neutropenia, fever and nodular pulmonary opacities suggestive of multifocal pneumonia. The patient subsequently developed a single, solitary necrotic crusted nodule on the right cheek. Skin biopsy demonstrated embolic vascular invasion with septate hyphae, dichotomous branching and minimal inflammation. Tissue culture revealed Aspergillus flavus. Despite systemic antifungal therapy with amphotericin B and granulocyte transfusions, the patient developed respiratory failure and died of disseminated aspergillosis, sepsis and renal failure. The clinical presentation of disseminated infection with Aspergillus flavus as a solitary embolic cutaneous lesion is extremely rare. We have reviewed other cases described in the literature and suggest this pattern of cutaneous involvement as more typical of disseminated infection with Aspergillus flavus. [source]
