BACKGROUND HIV-associated cryptococcal meningitis is the leading cause of adult meningitis in Sub-Saharan Africa, accounting for 15%-20% of AIDS-attributable mortality. The development of point-of-care assays has greatly improved the screening and diagnosis of cryptococcal disease. We evaluated a point-of-care immunoassay, StrongStep (Liming Bio, Nanjing, Jiangsu, China) lateral flow assay (LFA...
BACKGROUND (1→3)-β-d-Glucan (BDG) is a helpful diagnostic marker for many invasive fungal infections. However, BDG is not thought to be useful in diagnosing cryptococcosis. We evaluated the utility of BDG as an adjunct diagnostic tool for patients infected with human immunodeficiency virus (HIV) and presenting with suspected cryptococcal meningitis. METHODS The Fungitell assay was used to mea...
BACKGROUND Cryptococcal meningitis (CM) constitutes a significant source of mortality in resource-limited regions. Cryptococcal antigen (CRAG) can be detected in the blood before onset of meningitis. We sought to determine the cost-effectiveness of implementing CRAG screening using the recently developed CRAG lateral flow assay in Uganda compared to current practice without screening. METHODS...
BACKGROUND Cryptococcal meningitis is a major cause of HIV/AIDS-related deaths in Africa. Cryptococcosis is a neglected killer. However, meningitis can be prevented by early cryptococcal antigen (CrAg) screening and preemptive antifungal treatment during a prolonged period of detectable, subclinical infection. We determined the prevalence of cryptococcal antigenemia in comparison to CD4 count a...
BACKGROUND Globally, Latin America ranks third among regions with most cases of AIDS related cryptococcal meningitis. In 2009, a lateral flow immunoassay (LFA) for the detection of cryptococcal antigen (CrAg) was developed as a potential point-of-care test for diagnosis of cryptococcal infection. In 2011 World Health Organizations recommended on CrAg screening for HIV positive persons with CD4 ...
Cryptococcal meningitis is a disease that afflicts approximately 1 million human immunodeficiency virus (HIV)–infected individuals annually, with >600 000 deaths, predominantly in the developing world, where antiretroviral therapy is less available [1]. Therapy of cryptococcal meningitis has been poorly effective in resource-limited settings, where 10-week mortality rates have averaged 25%–30%,...
We report a case of myositis that resulted from disseminated cryptococcosis in a patient with hepatitis C cirrhosis. One year after cessation of treatment, the patient remains symptom free with negative results of serum cryptococcal antigen tests and negative culture results.
Four patients who had acquired immunodeficiency syndrome and who were evaluated for headache within a 3-week period had false-positive results of serum cryptococcal antigen tests. This cluster of false-positive test results appeared to be due to inactivation of the pronase vial in the test kit, a cause that has not been reported previously.
Background. Mortality for cryptococcal meningitis remains significant, in spite of available treatment. Resistance to first-line maintenance therapy, particularly fluconazole, has been reported. Methods. A retrospective chart review was performed on immunocompromised patients with cryptococcal meningitis, who had susceptibility testing performed between January 2001 and December 2011, at 3 ho...
The cryptococcal antigen lateral flow assay (CrAg LFA) was evaluated for the diagnosis of cryptococcosis in HIV-negative patients. The sensitivity was excellent, suggesting that this assay can replace conventional testing based on latex agglutination (LA). CrAg LFA and LA titers were correlated but were not directly comparable, with implications for conversion between assays.
