Aspergillus fumigatus and Chaetomium homopilatum in a leukemic patient. Pathogenic significance of Chaetomium species

Mycoses
H SchulzeL Balleisen

Abstract

From the tracheal secretion of a leukaemic patient Aspergillus fumigatus and Chaetomium homopilatum was isolated. Radiographically (HR-CT) an invasive pulmonary mycosis was diagnosed from which the patient died. As an autopsy was not performed, the role of the isolated fungi could not be clarified safely. Aspergillus fumigatus is supposed to have been responsible for the invasive mycosis. The etiopathological significance of Ch. homopilatum remained unclear. The isolation of Ch. homopilatum was a reason for reviewing the genus Chaetomium. In the literature 18 reported cases of infections by Chaetomium sp. were found. Ch. globosum was the most prevalent species and caused mostly onychomycosis. Ch. strumarium and Ch. atrobrunneum caused brain infections. The predisposing factor in case of onychomycosis and cutaneous lesions was a trauma, and the systemic mycoses were a consequence of leukaemia, renal transplantation, intravenous drug use or renal failure. The reported cases show, that Chaetomium sp. may cause infections, if predisposing factors are present. Therefore the isolation of Chaetomium sp. in clinical specimen should not regarded as a contamination, and the possible etiopathological significance should be clarified.

Aspergillosis

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
