The cryptococcal antigen (CRAG) lateral flow assay (LFA) had 100% sensitivity and specificity on cerebrospinal fluid samples. Pretreatment LFA titers correlated with quantitative cultures (R(2) = 0.7) and predicted 2- and 10-week mortality. The CRAG LFA is an accurate diagnostic assay for CSF and should be considered for point-of-care diagnosis of cryptococcal meningitis.
An enzymatic method involving a protease (pronase) for the elimination of interference factors in the latex test for cryptococcal antigen was developed and compared with dithiothreitol treatment. The two were equivalent in their ability to remove interference factors; however, the enzymatic method generally yielded higher titers. The method is simple, requires only 20 min, and makes the latex t...
The clinical presentations of cryptococcal meningitis in HIV-negative patients may be different from that infected with HIV. We report a case of 75-year old male with chronic lymphoid leukemia presenting with recurrent syncope, bi-frontal headache and diplopia. This case discusses the atypical presentations of cryptococcal meningitis in HIV-negative patients and its importance of early diagnosis.
Sera from nine patients with cryptococcal infections and from four with rheumatoid arthritis and positive rheumatoid factor were examined for the presence of cryptococcal capsular antigen by the latex agglutination method. Ethylenediaminetetraacetic acid-heat treatment of the sera before testing possibly increased sensitivity as compared with the untreated sera, and the interfering rheumatoid f...
Cryptococcal meningitis immune reconstitution inflammatory syndrome (IRIS) is frequently seen in patients with HIV and less frequently in patients on immune suppressive medications for other conditions. Here, we describe the first reported case of unmasking cryptococcal IRIS due to granulocyte colony-stimulating factor used in an HIV-negative patient with chemotherapy-induced neutropenia.
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 Cryptococcus neoformans is a ubiquitous environmental fungus that can cause life-threatening meningitis and fungemia, often in the presence of acquired immunodeficiency syndrome (AIDS), liver cirrhosis, diabetes mellitus, or other medical conditions. To distinguish risk factors from comorbidities, we performed a hospital-based, density-sampled, matched case-control study. METHODS A...
We describe donor-transmitted Cryptococcus neoformans infection in a renal transplant recipient. The donor had no apparent risk factors for cryptococcal infection. The disease in the recipient, who did not receive prophylaxis, manifested relatively late at 50 days post-transplantation. We discuss the epidemiology and management of cryptococcal disease in solid organ transplant recipients and le...
Treatment of cryptococcosis requires deferred initiation of antiretroviral therapy (ART). Early ART initiation may be detrimental in the context of cryptococcal infection by increasing the risk of immune reconstitution inflammatory syndrome (IRIS). We present 3 cases where early ART initiation in the presence of unrecognized cryptococcal disease had fatal outcomes.
