Cryptococcosis is a rare pediatric disease. The aim of the study is to describe clinical characteristics and prognosis of pediatric cryptococcosis from 2002 to 2014 in Beijing Children's Hospital. A total of 53 cases of cryptococcosis were identified, 69.8% of which were males. The mean age was 7 years. Forty-one (77.4%) patients had no underlying conditions. Fever, headache, and vomiting were the most common symptoms. The most common sites were the central nervous system (CNS), followed by the lungs. Most patients received a combination of amphotericin B and fluconazole with or without flucytosine as their initial regimen...

BACKGROUND: India ink microscopy on cerebrospinal fluid is still utilized in resource limited settings for the diagnosis of cryptococcal meningitis despite its poor sensitivity. We hypothesized that staining fungal nucleic acids with fluorescent dyes instead of the capsule with India ink might improve sensitivity for the diagnosis of cryptococcal meningitis. METHODS: We enrolled 96 HIV-infected participants with cryptococcal meningitis who provided 194 CSF specimens at serial time points in Kampala, Uganda...

Cryptococcosis is a lethal fungal infection mainly caused by Cryptococcus neoformans/C. gattii species. Currently, our understanding of cryptococcosis episodes in HIV-negative patients during renal dialysis remains scarce and fragmented. Here, we performed an analysis of pooled cases to systemically summarize the epidemiology and clinical characteristics of cryptococcosis among HIV-negative patients with renal dialysis. Using pooled data from our hospital and studies identified in four medical databases, 18 cases were identified and analyzed...

Cryptococcosis in HIV-seronegative patients is rarely reported from India. This prospective study was conducted to look for cryptococcal meningitis in HIV-seronegative individuals and compare their laboratory features to cryptococcal meningitis in HIV-seropositive patients. Cerebrospinal fluid was collected from 153 suspected cases of meningitis and subjected to India ink preparation, antigen detection, and culture. Nineteen samples tested positive for Cryptococcus neoformans infection. Seventeen and two patients were HIV reactive and nonreactive, respectively...

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 below 100 cells/μL, followed by preemptive fluconazole treatment. However, in Argentina no formal recommendations for CrAg screening have been issued...

BACKGROUND: HIV-infected persons with detectable cryptococcal antigen (CrAg) in blood have increased morbidity and mortality compared with HIV-infected persons who are CrAg-negative. This study examined neurocognitive function among persons with asymptomatic cryptococcal antigenemia. METHODS: Participants from three prospective HIV cohorts underwent neurocognitive testing at the time of antiretroviral therapy (ART) initiation. Cohorts included persons with cryptococcal meningitis (N = 90), asymptomatic CrAg + (N = 87), and HIV-infected persons without central nervous system infection (N = 125)...

Cryptococcus neoformans and Cryptococcus gattii, the predominant etiological agents of cryptococcosis, are fungal pathogens that cause disease ranging from a mild pneumonia to life-threatening infections of the central nervous system (CNS). C. neoformans is widely considered an opportunistic fungal pathogen which targets individuals with impaired immune systems, while C. gattii is predominantly associated with fungal infections in immunocompetent individuals. However, C. neoformans and C. gattii have certainly been identified as the causative agent of cryptococcosis in both immune compromised and immune competent individuals...

Cryptococcosis is a potentially fatal fungal disease caused by the basidiomycetes yeasts Cryptococcus neoformans and C. gattii with high predilection to invade the central nervous system mainly in immunocompromised hosts. Skin can be secondarily involved in disseminated infection or be exceptionally involved as primary cutaneous infection by inoculation with contaminated materials. We report the first two Libyan cases of cryptococcal meningitis in HIV patients, in which one of them presented a secondary cutaneous involvement due to systemic dissemination...

Detection of Cryptococcus antigen (CrAg) is invaluable for establishing cryptococcal disease. Multiple different methods for CrAg detection are available, including a lateral flow assay (LFA). Despite excellent performance of the CrAg LFA, we have observed multiple cases of low-titer (≤1:5) positive CrAg LFA results in patients for whom cryptococcosis was ultimately excluded. To investigate the accuracy of low-titer positive CrAg LFA results, we performed chart reviews for all patients with positive CrAg LFA results between June 2014 and December 2016...

BACKGROUND: Cryptococcal meningitis (CM) is a common, life-threatening opportunistic infection (OI) among people living with HIV (PLHIV) in India. Serum Cryptococcal antigen (CrAg) positivity is predictive of future occurrence of CM and pre-emptive treatment reduces its mortality. Routine CrAg screening among PLHIV is not adopted by India's national programme. This study evaluated the prevalence of CrAg and assessed CrAg positivity in predicting all-cause mortality among PLHIV. METHODS: This prospective study was conducted in a tertiary care, public health facility in New Delhi, India...

We present a case of cryptococcosis with adrenal insufficiency and meningitis in a healthy host without any risk factors. Antifungal therapy did not reduce the cryptococcal antigen titers of the cerebrospinal fluid and serum or the bilateral adrenal gland enlargement. It was suggested that the adrenal glands were the focus of persistent fungemia. Removal of both adrenal glands brought about a response to antifungal therapy. We conclude that if antifungal therapy is ineffective, bilateral adrenalectomy is an effective measure for treatment of such patients...

We clarified the performance of a cryptococcal glucuronoxylomannan (GXM) antigen test using bronchoalveolar lavage fluid (BALF) samples, in an HIV-negative Japanese population. Between March 2008 and December 2014, we examined cryptococcal GXM antigens in both serum and BALF specimens from 429 cases at Nagasaki University hospital. The diagnoses, underlying diseases, chest computed tomography findings, and cryptococcal GXM antigen test results were retrospectively investigated. Twenty-three patients were confirmed to have pulmonary cryptococcosis, another six were clinically diagnosed with cryptococcosis because they were seropositive for the GXM antigen, and five possible cryptococcosis cases had BALF samples that were positive for the GXM antigen and serum samples that were negative...
