Deoxycholate amphotericin B (d-AMB) has a higher rate of acute kidney injury (AKI) in comparison of lipid formulations. However, lipid amphotericin B has high costs in developing countries. The aim of this study is to assemble a model of cost-minimization of amphotericin B lipid complex (ABLC) in patients with cryptococcal meningitis. This is a retrospective study done in a cohort of patients with cryptococcal meningitis to study the economic impact of its use in developing countries. Cost analysis were based on direct cost of different antifungal therapies, chronic dialysis after discharge, and survival of patients based on a retrospective cohort of 102 patients infected with human immunodeficiency virus with confirmed diagnosis of cryptococcal meningitis...

Cryptococcus neoformans is not usually considered a cytotoxic fungal pathogen but there is considerable evidence that this microbe can damage host cells and tissues. In this essay, we review the evidence that C. neoformans damages host cells and note that the mechanisms involved are diverse. We consider C. neoformans -mediated host damage at the molecular, cellular, tissue, and organism level. Direct mechanisms of cytotoxicity include lytic exocytosis, organelle dysfunction, phagolysosomal membrane damage, and cytoskeletal alterations...

Although the infectious diseases tuberculosis (TB) and cryptococcosis both cause formation of single or multiple nodules in immunodeficient hosts, cases of co-infection of these diseases are rarely seen. We report a patient who was co-infected with TB and cryptococcosis. A male patient with no clinical evidence of immunodeficiency presented with a 3-week history of abdominal distension accompanied by oedema of recurring lower extremities. The patient was diagnosed with tuberculous peritonitis and tuberculous pleurisy by an abdominal puncture biopsy...

A 52-year-old white diabetic male with 4-weeks history of persistent cough followed by headache, drenching night sweats, low-grade fever, worsening photophobia, nausea and vomiting was presented. Examination was significant for photophobia and diminution of vision. His spinal fluid and blood cultures were positive for Cryptococcus neoformans Intravenous fluconazole were given for 2 weeks followed by oral fluconazole. There was significant improvement in systemic and ocular symptoms. HIV serology was negative, but his CD4 counts were low with inverted CD4:CD8 ratio...

Cryptococcosis diagnosis has been recently improved by the use of rapid cryptococcal antigen testing with lateral flow assays, which have proved sensitive and specific. Using "test and treat" screening strategies for cryptococcal disease with these tests has been showed effective in reducing cryptococcal meningitis (CM) in HIV-infected patients. Recommended induction, consolidation, and maintenance therapeutic strategy for CM is widely unavailable and/or expensive in low and middle-income settings...

Many infectious diseases disproportionately affect people in the developing world. Cryptococcal meningitis is one of the most common mycoses in HIV-AIDS patients, with the highest burden of disease in sub-Saharan Africa. Current best treatment regimens still result in unacceptably high mortality rates, and more effective antifungal agents are needed urgently. Drug development is hampered by the difficulty of developing effective antifungal agents that are not also toxic to human cells, and by a reluctance among pharmaceutical companies to invest in drugs that cannot guarantee a high financial return...

PURPOSE OF REVIEW: Cryptococcosis has become a common opportunistic infection among non-HIV immunocompromised hosts. Recent reports have shown the incidence of Cryptococcosis among HIV-negative immunocompromised patients reaches close to half of the overall cases reported in the USA. Management of this infection in this population carries unique challenges. We aim to review relevant and recent research findings to develop treatment recommendations for this type of population. RECENT FINDINGS: Most of the recommendations for the management of non-HIV immunocompromised host are extrapolated from HIV studies...

Cryptococcosis is a menacing opportunistic infection most commonly affecting immunocompromised individuals. Its occurrence in immunocompetant individuals is uncustomary. Disseminated cryptococcosis is subtile in immunocompetent individuals. Cryptococcosis presenting with myriad of symptoms with involvement of lung, meninges, hematological system is rare. We present to you a unique case of disseminated cryptococcosis presenting as bilateral pulmonary nodular opacities with peripheral eosinophilia and meningitis along with a narration of the enthralling diagnostic process...

BACKGROUND: Cryptococcosis is an important opportunistic infection of organ transplant recipients. It is the third most common fungal infection of transplant patients and occurs especially in kidney recipients. Cryptococcus neoformans is a ubiquitous fungus which infects humans by inhalation of spores. C. gattii has more recently been recognised as a pathogen. Infection commonly is disseminated affecting mainly the central nervous system and the lungs. Cryptococcoma, a localised form of the disease, has been described in various organs...

BACKGROUND: Cryptococcosis is the second most common cause of invasive fungal infections in renal transplant recipients in many countries, and data on graft outcome after treatment for this infection is lacking in less-resourced health care settings. METHODS: Data from 47 renal transplant recipients were retrospectively collected at a single institution during a period of 13 years. Graft dysfunction, graft loss and mortality rates were evaluated. Predictors of mortality and graft loss were estimated...

The Pacific Northwest outbreak of cryptococcosis, caused by a near-clonal lineage of the fungal pathogen Cryptococcus gattii, represents the most significant cluster of life-threatening fungal infections in otherwise healthy human hosts currently known. The outbreak lineage has a remarkable ability to grow rapidly within human white blood cells, using a unique 'division of labour' mechanism within the pathogen population, where some cells adopt a dormant behaviour to support the growth of neighbouring cells...

REVIEW

Cryptococcosis, a fungal disease arising from the etiologic agent Cryptococcus neoformans , sickens a quarter of a million people annually, resulting in over 180,000 deaths. Interestingly, males are affected by cryptococcosis more frequently than females, a phenomenon observed for more than a half century. This disparity is seen in both HIV− (~3M:1F) and HIV⁺ (~8M:2F) populations of cryptococcal patients. In humans, male sex is considered a pre-disposing risk factor for cryptococcosis and males suffering from the disease have more severe symptoms and poorer outcomes...

Cryptococcosis is an invasive fungal disease caused by Cryptococcus neoformans and the closely related species C. gattii. The severe form of the disease, cryptococcal meningitis (CM), is rapidly fatal without treatment. Although typically a disease of immunocompromised (especially HIV-positive) individuals, there is growing awareness of cryptococcal disease amongst non-immunocompromised patients. Whilst substantial progress has been made in understanding the pathogenicity of C. neoformans in HIV patients, prospective data on cryptococcosis outside the context of HIV remains lacking...

Cryptococcus neoformans is one of the most lethal fungi causing mortality across the globe with the highest incidences in immuno-compromised person. Patients taking immuno-suppressive medications and immuno-competent hosts are extremely susceptible to its infection. Thus, new forms of therapy are urgently required for effective cure to the fungal burden. So, in the present study we have tried to explore the potential effects of amphotericin B (AMB) and fluconazole (FLC) in combination antifungal drug therapy...

Cutaneous cryptococcosis is usually secondary to the hematogenous dissemination of pulmonary or meningeal Cryptococcus neoformans. Primary cutaneous cryptococcosis (PCC) is a rare form of the infection, typically caused by direct inoculation from trauma to the skin [1]. Most cases of PCC present as a localized cellulitis, abscess, nodule, or ulceration. Herein, we present a case of a rapidly spreading cellulitis characterized by bullae and ulceration, caused by direct inoculation from a fall.

Pulmonary infections from the environmental fungus Cryptococcus gattii ( C. gattii ) are notable for cryptococcomas, which are usually solitary and can be very large. As with infections with Cryptococcus neoformans (C. neoformans) patients can have concomitant cryptococcal meningitis; however, unlike for C. neoformans, infections with C. gattii often occur in immunocompetent patients. The highest published incidence of C. gattii infection has been in the Indigenous Australian population of Arnhem Land in the tropical north of the country...
