Cryptococcosis has been one of the most common opportunistic infections and causes of mortality among HIV-infected patients, especially in resource-limited countries. Cryptococcal meningitis is the most common form of cryptococcosis. Laboratory diagnosis of cryptococcosis includes direct microscopic examination, isolation of Cryptococcus from a clinical specimen, and detection of cryptococcal antigen. Without appropriate treatment, cryptococcosis is fatal. Early diagnosis and treatment is the key to treatment success...

Post-transplant lymphoproliferative disorder (PTLD) is associated with a variety of clinical presentations, but rarely involves the skin. We herein report a case of PTLD presenting with skin ulceration in a renal transplant recipient. A biopsy of the ulcer confirmed the diagnosis of diffuse large B-cell lymphoma. The patient was initially treated with immunosuppression reduction, but the skin ulcer persisted. He was then treated with two courses of chemotherapy, but his condition was complicated with cryptococcal infection...

HIV-associated cryptococcal meningitis is by far the most common cause of adult meningitis in many areas of the world that have high HIV seroprevalence. In most areas in Sub-Saharan Africa, the incidence of cryptococcal meningitis is not decreasing despite availability of antiretroviral therapy, because of issues of adherence and retention in HIV care. In addition, cryptococcal meningitis in HIV-seronegative individuals is a substantial problem: the risk of cryptococcal infection is increased in transplant recipients and other individuals with defects in cell-mediated immunity, and cryptococcosis is also reported in the apparently immunocompetent...

Emerging infections caused by fungi have become a widely recognized global phenomenon and are causing an increasing burden of disease. Genomic techniques are providing new insights into the structure of fungal populations, revealing hitherto undescribed fine-scale adaptations to environments and hosts that govern their emergence as infections. Cryptococcal meningitis is a neglected tropical disease that is responsible for a large proportion of AIDS-related deaths across Africa; however, the ecological determinants that underlie a patient's risk of infection remain largely unexplored...

Cryptococcal spine infections are rare infections that are easy to misdiagnose and difficult to cure. Therefore, we report the case of a 25-year-old man who presented with nonspecific spinal lesions at L1 and S1. The patient underwent surgical removal of the lesions, and specimens were submitted for microbial identification, which identified a cryptococcal infection that was susceptible to amphotericin B. The patient exhibited marked improvement after receiving intravenous amphotericin B and remained asymptomatic (no back pain, fever, or other symptoms) at the 3‑ and 9‑month follow-ups...

We herein report the case of a 63-year-old man who presented with a 3-month history of a cutaneous nodular lesion of his jaw, low grade fever, lethargy and progressive cognitive impairment. He had a 30-year history of multiple sclerosis and had been treated with fingolimod for the previous 2 years. Laboratory data revealed CD4 lymphocytopenia and a tissue culture of the skin nodule was positive for Cryptococcus neoformans. Cerebrospinal fluid and serum cryptococcal antigen tests were also positive and we diagnosed him to have disseminated cryptococcosis...

Cryptococcus is a ubiquitous fungus and is known for causing meningitis and cutaneous infections in immunocompromised individuals. Disseminated cryptococcal infection is very rare and almost always found to occur in immunocompromised individuals especially in persons infected with HIV. This is particularly attributed to its capsulated spores. But there are few reported cases in which it has been found to cause disseminated infections even in immunocompetent individuals. We report a similar case of disseminated cryptococcal infection in an immunocompetent host...

Invasive fungal infections (IFI) are an emerging problem worldwide with invasive candidiasis and candidemia responsible for the majority of cases. This is predominantly driven by the widespread adoption of aggressive immunosuppressive therapy among certain patient populations (e.g., chemotherapy, transplants) and the increasing use of invasive devices such as central venous catheters (CVCs). The use of new immune modifying drugs has also opened up an entirely new spectrum of patients at risk of IFIs. While the epidemiology of candida infections has changed in the last decade, with a gradual shift from C...

Cryptococcus neoformans is pathogenic yeast, responsible for highly lethal infections in compromised patients around the globe. C. neoformans typically initiates infections in mammalian lung tissue and subsequently disseminates to the central nervous system where it causes significant pathologies. Virulence genes of C. neoformans are being characterized at an increasing rate, however, we are far from a comprehensive understanding of their roles and genetic interactions. Some of these reported virulence genes are scattered throughout different databases, while others are not yet included...

BACKGROUND: Early mortality among HIV-positive adults starting antiretroviral therapy (ART) remains high in resource-limited settings, with tuberculosis (TB) the leading cause of death. However, current methods to estimate TB-related deaths are inadequate and most autopsy studies do not adequately represent those attending primary health clinics (PHCs). This study aimed to determine the autopsy prevalence of TB and other infections in adults enrolled at South African PHCs in the context of a pragmatic trial of empiric TB treatment ("TB Fast Track")...

Immune reconstitution inflammatory syndrome in meningitis caused by Cryptococcus gattii in immunocompetent patients after initiation of antifungal therapy appears to be the result of paradoxical antifungal treatment-induced clinical deterioration due to improved local immune responses to cryptococcal organisms. Recent anecdotal reports have suggested a favorable clinical response to corticosteroids in select patients with C. gattii central nervous system (CNS) infections. In this report, we describe a 65-year-old patient with meningoencephalitis caused by C...

We report a case of cryptococcal sinusitis, a rare presentation of Cryptococcus neoformans infection in a patient with multiple myeloma. The objective of this case report is to highlight the utility of structural and functional imaging modalities in the differential diagnosis of sinonasal soft tissue masses in the immunocompromised patient population. PET-CT was the first imaging modality in this patient, who presented for routine follow-up staging of multiple myeloma, and was asymptomatic at the time of his presentation...

Advanced age and associated comorbidities are-recognized predictors of life-threatening adverse outcomes, such as opportunistic infection following immunosuppressive therapy. We describe the case of an elderly patient with stricturing colonic Crohn's disease and significant clinical comorbidities, initially controlled with corticosteroid induction followed by infliximab, whose course was complicated by fatal disseminated cryptococcal infection and posterior reversible encephalopathy syndrome. Our patient's case highlights rare, but serious, complications of immunosuppression...

BACKGROUND: HIV-associated vasculopathy and opportunistic infections (OIs) might cause vascular atherosclerosis and aneurysmal arteriopathy, which could increase the risk of incident stroke. However, few longitudinal studies have investigated the link between HIV and incident stroke. This cohort study evaluated the association of HIV and OIs with incident stroke. METHODS: We identified adults with HIV infection in 2000-2012, using the Taiwan National Health Insurance Research Database...
