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...

CASE SUMMARY: A 5-month-old feral kitten developed worsening respiratory signs, including tachypnea, coughing and wheezing after standard anthelmintic treatment with fenbendazole at a local shelter. The kitten was referred to the University of California, Davis, William R Pritchard Veterinary Medicine Teaching Hospital for further evaluation. Thoracic radiographs revealed a severe diffuse bronchointerstitial pattern with bronchial cuffing, ill-defined nodules and lymphadenomegaly. Differentials included infectious etiologies such as toxoplasmosis, feline infectious peritonitis and cryptococcosis...

Cryptococcal meningitis (CM) is a life-threatening infection in HIV-infected patients, especially in resource-limited settings. Cytokine patterns in the cerebrospinal fluid (CSF) and sera may be related to clinical outcomes. This study aimed to evaluate cytokine patterns in the CSF and sera of HIV-infected patients with CM as well as the cytokines produced by peripheral blood mononuclear cells (PBMCs) when stimulated with LPS and cryptococcal GXM. CSF and serum levels of IL-2, IL-4, IL-8, IL-10, IL-12p40, IL-17A, INF-γ, TNF-α and CXCL-10 were measured in HIV-infected patients with CM (CM+ HIV+) at various time points...

We report 2 cases of disseminated cryptococcosis with central nervous system involvement in patients with chronic lymphoid malignancies occurring within 1 month of starting on ibrutinib. Characteristically, in both cases, no inflammation was seen in the cerebrospinal fluid. Central nervous system mycoses should be considered as a potential complication of ibrutinib.

Cryptococcosis usually occurs in immunocompromised patients and can cause enlargement of the adrenal glands, although the morphologic changes after treatment have not been reported in detail. We report the case of 24-year-old man with fevers, headaches, and impaired consciousness who had been treated with glucocorticoids for a protein-losing gastroenteropathy. The cerebrospinal fluid analysis revealed cryptococcal meningitis. Computed tomography showed bilateral adrenal enlargement. A retrospective analysis revealed that the enlargement had been detected 5 months before admission and gradually increased...

The pharmacokinetic profile of posaconazole in clinically normal koalas (n = 8) was investigated. Single doses of posaconazole were administered intravenously (i.v.; 3 mg/kg; n = 2) or orally (p.o.; 6 mg/kg; n = 6) with serial plasma samples collected over 24 and 36 hr, respectively. Plasma concentrations of posaconazole were quantified by validated high-performance liquid chromatography. A noncompartmental pharmacokinetic analysis of data was performed. Following i.v. administration, estimates of the median (range) of plasma clearance (CL) and steady-state volume of distribution (Vss ) were 0...

BACKGROUND: Cryptococcus neoformans is responsible of cryptococcosis, a life-threatening infection that affects healthy and immunocompromised individuals. It is the first cause of adult acute meningitis in some sub-Saharan African countries with a mortality rate of about 100% in cases of inappropriate therapy. This study aimed at examining the occurrence and the antifungal patterns of Cryptococcus isolates from pigeon droppings and bat guanos in the west region of Cameroon. METHODS: A total of 350 samples were randomly collected from three selected localities of west region of Cameroon...

Cryptococcosis caused by Cryptococcus gattii leads to pneumonia and meningoencephalitis, and has a high mortality rate worldwide due to the inadequacy of available therapy and increasing drug resistance. There is a need to develop effective treatments, and drug repositioning is an interesting alternative to achieve new strategies to treat cryptococcosis. Atorvastatin (ATO), a statin currently used to treat hypercholesterolaemia, was tested in this study as an adjuvant to control infections caused by C. gattii...

BACKGROUND: Cryptococcosis is an opportunistic infection caused by the encapsulated yeast Cryptococcus neoformans and most remarkably manifests in HIV-infected individuals, especially in the settings of very low CD4 count. Development of cryptococcosis in HIV-uninfected individuals is exceedingly rare and usually signifies a marked immunodeficiency. Cryptococcosis in association with myasthenia gravis or thymoma has been previously documented in only very few cases in the literature. CASE PRESENTATION: We reported a complicated case of severe cutaneous cryptococcosis in a 39-year-old Vietnamese male patient with myasthenia gravis on long-term immunosuppressive therapy...

The antifungal effects of ambroxol (Amb; the metabolite VIII of bromhexine) against Cryptococcus planktonic cells and mature biofilms were investigated in this study. Amb showed antifungal activity against planktonic cells and mature biofilms. Disk diffusion test similarly showed antifungal profile for planktonic cells. Furthermore, Amb was found to be synergetic with fluconazole against planktonic cells and reduced the adherence of cells to polystyrene. Our results suggest that Amb can inhibit cryptococcal cells and biofilms, indicating its potential role in the prevention and treatment of cryptococcosis...

Cryptococcosis is a significant invasive fungal infection with noteworthy morbidity and mortality that is usually caused by either Cryptococcus neoformans (C. neoformans) or Cryptococcus gattii (C. gattii). Epidemiological studies have indicated that C. neoformans are more often reported in immunocompromised and immunocompetent patients. It has been well established that the cytokine profile of the host markedly affects the outcome of cryptococcal disease, and the negative regulators of microRNAs(miRs or miRNAs) are critically important for immunomodulation...

Invasive fungal infections, including cryptococcosis, are a growing threat to immunocompromised patients. Although Cryptococcus neoformans and Cryptococcus gattii are the main agents of human cryptococcosis, opportunistic infections by environmental species, such as C. liquefaciens, have been observed recently. The main Cryptococcus virulence factor is the production and secretion of polysaccharides (PS). Previously, we showed that both species produce PS of similar composition. Here, we examined the ultrastructure and biological activity of capsular and secreted PS from C...

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...

Cryptococcus neoformans is the most lethal pathogen of the central nervous system. The gold standard treatment of cryptococcosis, a combination of amphotericin B with 5-fluorocytosine, involves broad toxicity, high costs, low efficacy, and limited worldwide availability. Although the need for new antifungals is clear, drug research and development (R&D) is costly and time-consuming. Thus, drug repurposing is an alternative to R&D and to the currently available tools for treating fungal diseases. Here we screened a collection of compounds approved for use in humans seeking for those with anti-cryptococcal activity...
