Yeasts belonging to the genus Hansenula are rarely encountered as the
cause of infection in clinical practice. A wide spectrum of infections
caused by these fungi can be seen, ranging from asymptomatic fungaemi
a to severe disease. Mie describe an outbreak of 24 cases of infection
due to H. anomala in an oncological hospital in Rio de Janeiro, Brazi
l. The median age of the patients was 11 years, of whom 54.2% were fem
ale; 91.7% of the Hansenula fungaemia occurred in the haematology unit
. The most frequent primary disease diagnosis was leukaemia (62.5%), a
nd all of those infected had had a central venous catheter or peripher
al venous catheter and had been treated previously with broad-spectrum
antibiotics. Numerous other risk factors were observed in our cases:
previous use of steroids, chemotherapy, radiation therapy and neutrope
nia (data not shown). No deaths could be attributed to Hansenula.
