Early cryptococcal disease can be detected via circulating antigen in blood before fulminant meningitis develops, when early antifungal therapy improves survival. Two semiquantitative cryptococcal antigen (CrAg) lateral flow assays (LFAs) have been developed, but their diagnostic performance has not been defined. Cryopreserved serum samples from HIV-infected Ugandans obtained as part of a prospective CrAg-screening cohort were tested in duplicate for CrAg by the CrAgSQ (IMMY) and CryptoPS (Biosynex) lateral flow assays. Case-controlled diagnostic performance was measured using the FDA-approved CrAg LFA (IMMY) as a referenc...

Authors: Kano R, Sugita T, Kamata H Abstract Ravuconazole (RVCZ) is a newly available human azole drug in Japan since 2018 and is a broad-spectrum antifungal agent that exhibits excellent activity against Candida albicans and Cryptococcus neoformans (formerly: Cryptococcus grubii). The drug is also highly active against isolates that are resistant to fluconazole (FLCZ). In the present study, the in vitro susceptibility to ravuconazole (RVCZ) of Japanese clinical isolates and multi-azole-resistant strains of C. neoformans was investigated using the Clinical &Laboratory Standards Institute (CLSI) M27-A3 test. The...

It is a non-selective sphingosine1-phosphate (S1P) receptor modulator on lymphocytes. Engagement of this receptor blocks the T cells and B cells migration from the lymph nodes into the inflamed central nervous system (CNS) via bloodstream. In spite of this known immunomodulatory mechanism, there are some reports about...

In this study, we characterized laccase activity in C. neoformans and C. gattii isolates from Thailand and investigated whether C. gattii that is deficient in laccase might modulate immune responses during infection. C. gattii was found to have higher laccase activity than C. neoformans, indicating the importance of laccase in the pathogenesis of C. gattii infection. The expression of laccase promoted intracellular proliferation in macrophages and inhibited in vitro fungal clearance. Mice infected with a lac1 mutant strain of C. gattii had reduced lung burdens at the early but not the late stage of infection. Without affec...

Activated B cells modulate infection by differentiating into pathogen-specific antibody-producing effector plasmablasts/plasma cells, memory cells, and immune regulatory B cells. In this context, the B cell phenotypes that infiltrate the central nervous system during human immunodeficiency virus (HIV) and cryptococcal meningitis coinfection are ill defined. We characterized clinical parameters, mortality, and B cell phenotypes in blood and cerebrospinal fluid (CSF) by flow cytometry in HIV-infected adults with cryptococcal (n = 31) and noncryptococcal (n = 12) meningitis and in heathy control subjects with neither infectio...
