Study acronymBK Study
Study hypothesisCryptococcal meningitis is the second leading cause of death in Human Immunodeficiency Virus (HIV) patients worldwide after Tuberculosis (TB). The Hospital for Tropical Diseases has seen a dramatic increase in the number of cases of cryptococcal meningitis as the HIV epidemic has accelerated in Viet Nam. The mortality rate is high, even with treatment according to international guidelines. Optimum treatment for cryptococcal meningitis is not determined. Combination treatment with amphotericin and flucytosine has shown no clinical benefit when compared with amphotericin alone, yet this combination of potentially toxic drugs has become the standard of care, recommended in US and European guidelines.

The azole drugs, with their ease of administration and good safety profile, have not been investigated in combination with amphotericin in the treatment of cryptococcal meningitis. The trial will determine whether amphotericin combined with high dose fluconazole is superior to amphotericin alone or amphotericin combined with flucytosine, using clinical endpoints.

As of 18/03/2009 the anticipated trial dates of this record have been updated; the intial trial dates at the time of registration were:
Initial anticipated start date: 01/04/2004
Initial anticipated end date: 01/01/2006
Ethics approval(s)The ethical review board of the Hospital for Tropical Diseases, Ho Chi Minh City, and Liverpool School of Tropical Medicine, UK gave approval prior to participant recruitment.
