AIM: To produce and test recombinant multiepitope proteins as an alternative assay for the serological diagnosis of cryptococcosis. MATERIALS & METHODS: Previously, synthetic peptides were used to detect anti-Cryptococcus antibodies, and in silico analyses showed that the union of peptides would improve the results. Here, the coding sequences of these peptides were assembled into synthetic genes. Four genes have been cloned and expressed in Escherichia coli, producing recombinant multiepitope proteins: proteins A, B, C and D...

Case: Disseminated cryptococcosis is a well-recognized condition among HIV patients, but it also occurs in non-HIV patients. Necrotizing fasciitis caused by cryptococcus is rare. An 81-year-old man who had received steroid therapy presented with erythema and pain in his right thigh. After the rapid progression of symptoms and a failure to respond to antibiotic therapy, a clinical diagnosis of necrotizing fasciitis was made. We performed debridement, and yeasts were detected using a Gram stain of the fascia...

Pulmonary cryptococcosis is most commonly reported in immunocompromised patients, whereas immunocompetent hosts are rarely affected and may be asymptomatic, resulting in reduced diagnostic performance of computed tomography (CT) imaging. Thus, the aim of the present study was to review the plain and contrast-enhanced chest CT scan findings of primary pulmonary cryptococcosis in immunocompetent patients, with the aim of improving the diagnosis of this type of pulmonary disease. In the present study, a total of 27 immunocompetent patients of clinically confirmed pulmonary cryptococcosis were analyzed retrospectively...

BACKGROUND Cryptococcus neoformans (C. neoformans) infection is one of the most common opportunistic infections in AIDS patients. C. neoformans usually infects the central nervous system (CNS) and/or lungs with typical clinical manifestation. CASE REPORT Here, we report the case of a 52-year-old HIV-1-infected man with disseminated cryptococcosis, including subacute meningitis, pulmonary, and cutaneous cryptococcosis, but only skin lesion served as the chief complaint. Moreover, the results of cerebrospinal fluid (CSF) tests and lung computed tomography (CT) scan were atypical...

Infections occur more frequently in patients receiving biologics. However, cryptococcal infection is uncommon in patients receiving tocilizumab, an interleukin-6 inhibitor, in contrast to patients receiving tumor necrosis factor-α inhibitors. In this report, we describe a case of disseminated cryptococcosis in a 55-year-old man who was receiving tocilizumab every 2 weeks along with daily prednisolone and cyclosporine for Castleman's disease. He initially developed cellulitis on both upper limbs, and his condition worsened despite antibacterial therapy...

Lobomycosis is a chronic skin mycosis endemic in Amazon regions characterized by chronic nodular or keloidal lesions caused by Lacazia loboi, an uncultivable fungus. Imported cases in nonendemic countries are rare and diagnosed after years. We describe a case of lobomycosis in a healthy 55-year-old Italian traveler who had acquired the infection during 5-day-honeymoon in the Amazon region of Venezuela in 1999. Several weeks after return, he recalled pruritus and papular skin lesions on the left lower limb, subsequently evolving to a plaque-like lesion...

Cryptococcal disease, caused by Cryptococcus neoformans and Cryptococcus gattii, is associated with significant morbidity and mortality but limited data exist on its incidence and impact. A study utilizing the Nationwide Inpatient Sample from 2000 to 2007 to examine the epidemiology and impact of cryptococcal disease in the United States was undertaken. The International Classification of Diseases 9th Version code was used to identify hospital discharges with diagnosis of Cryptococcus (117.5). Our primary outcome was the incidence rate of cryptococcal admissions...

Crytococcus neoformans is an encapsulated yeast that frequently affects immune-compromised patients, although increasingly being detected in the immune-competent host as well. We report a case of disseminated cryptococcosis in a young child in whom no immune deficiency was yet identified. A 4-year-old child presented with high-grade fever, intermittent abdominal pain and generalized skin eruptions for the past two months. He had pallor, firm lymphadenopathy, skin lesions with scarring and firm hepatosplenomegaly...

Fungal osteomyelitis of the hand is rare with limited evidence-based literature to guide diagnosis and management. We report a case of disseminated cryptococcal osteomyelitis in the middle phalanx from a pulmonary fungal infection in a patient with a history of lymphoplasmacytic lymphoma. Although rare, cryptococcosis should be considered in the differential diagnosis of aggressive lytic lesions with bone pain and associated large soft tissue masses, especially in the immunosuppressed host.

Cryptococcosis is a rare opportunistic infection in the immunocompromised host.1,2 Diagnosis of disseminated fungal infections is rarely thought of in immunocompetent hosts. In developing countries where tuberculosis is endemic, Cryptococcosis is often misdiagnosed as tuberculosis.3,4 A 14 year old girl, misdiagnosed as miliary tuberculosis with Koch's abdomen on ATT, presented with seizures. After extensive workup, she was found to have disseminated Cryptococcosis, not tuberculosis. This case report shows the similarity in presentation of tuberculosis and Cryptococcosis, and hence Cryptococcosis should always be kept as a differential diagnosis of tuberculosis...

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...

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...

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...

REVIEW
Tomotaka Sato
Understanding deep cutaneous fungal infection requires not only reading many case reports and checking the typical clinical images of skin lesions, but also managing the patients properly to prevent misdiagnosis. Herein, I review my recent experiences with eight typical cases of deep cutaneous infections (including protothecosis and nocardiosis) in Japan. It is very important to do the four management processes; namely, KOH direct microscopic examination, skin biopsy, fungal culture, and microscopic examination of the histopathological specimen of PAS and Grocott staining...

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...
