BACKGROUND: Classic histoplasmosis is a systemic endemic mycosis due to Histoplasma capsulatum var. capsulatum. A significant reduction in the morbidity and mortality of AIDS-related histoplasmosis has been observed since the introduction of highly active antiretroviral therapy (HAART) and secondary antifungal prophylaxis. AIMS: The aim of this study was to determine the current state of prognosis and treatment response of HIV-positive patients with histoplasmosis in the Francisco J...

Histoplasmosis in central Europe is a rare fungal disease with diverse clinical presentations. Apart from acute pulmonary histoplasmosis and involvement of the central nervous system, the most serious clinical presentation is progressive disseminated histoplasmosis which is generally associated with severe immunodeficiency and in particular, advanced HIV-infection. Here we report on an immunocompetent female residing in a non-endemic area, presenting with progressive disseminated histoplasmosis after a remote travel history to Thailand and Costa Rica...

Histoplasmosis is a genus of dimorphic fungi having various varieties of which the commonest one causing infection is Histoplasma capsulatum known to cause histoplasmosis. It has a varied disease spectrum ranging from an acute infection to chronic disease especially in lungs, disseminated disease and cutaneous disorder. Histoplasma capsulatum usually causes subclinical infection and serious infections only manifest in immunocompromised patients. Frank cases of infection are seen in pulmonary histoplasmosis...

Early human immunodeficiency virus (HIV) infection leads to transient immunosuppression followed by a quasi-homeostatic state with slow progression towards AIDS. Histoplasmosis has never been reported in early HIV. We present a case of disseminated histoplasmosis with documented recent seroconversion and review the literature regarding other opportunistic infections in early HIV.

Guatemala is a developing country in Central America with a high burden of HIV and endemic fungal infections; we attempted to estimate the burden of serious fungal infections for the country. A full literature search was done to identify epidemiology papers reporting fungal infections from Guatemala. We used specific populations at risk and fungal infection frequencies in the population to estimate national rates. The population of Guatemala in 2013 was 15.4 million; 40% were younger than 15 and 6.2% older than 60...

BACKGROUND: The prevalence of the Histoplasma capsulatum var. capsulatum (Hcc) histoplasmosis may be underestimated West Africa, both because the diagnosis is not mentioned in the early stages of the disease and due to limited biological resources available. CASE REPORT: We report a case of disseminated histoplasmosis due to Hcc in a Senegalese HIV patient. The diagnosis was suspected following the demonstration of small encapsulated yeasts within neutrophils on a thin blood smear...

Histoplasmosis is the most common endemic mycoses among HIV-infected people. Patients with suppressed cell immunity mainly due to HIV are at increased risk of disseminated disease. Dermatological manifestations of immune reconstitution inflammatory syndrome (IRIS) and cutaneous manifestations of histoplasmosis similar to an IRIS event have been previously described. We report the case of a 43-year-old male who presented with cutaneous disseminated histoplasmosis due to Histoplasma capsulatum var. capsulatum 4 months after the onset of the antiretroviral therapy and some improvement in the immune reconstitution...

In Bangladesh there are several published papers on superficial mycoses. Deep mycoses are also recognized as an important emerging problem. Here, we estimate the annual incidence and prevalence of serious fungal infections in Bangladesh. Demographic data were obtained from world population reports and the data on TB and HIV extracted from the online publications on tuberculosis in Bangladesh and Asia Pacific research statistical data information resources AIDS Data HUB. All the published papers on fungal infections in Bangladesh were identified through extensive search of literature...

Introduction. Hemophagocytic lymphohistiocytosis (HLH), a rare but potentially fatal disease, is characterized by excessive immune activation and cytokine release which stimulates bone marrow macrophages to engulf hematopoietic cells. HLH could be secondary to infections: viral, fungal, and bacterial; malignancies and autoimmune diseases. The diagnosis of HLH is usually delayed due to the presence of non-specific symptoms at presentation. This delay contributes to increased mortality. Cases and review. We present the case of 4 patients who presented with subjective fevers and extreme fatigue...

A retrospective study was carried out on 171 cases of disseminated histoplasmosis diagnosed in HIV/AIDS patients during the period 2009-2014. Although HIV diagnosis rates remained stable over the study period, a sensible increase in the number of histoplasmosis cases was observed in the last three years. Disseminated histoplasmosis was prevalent in males with an average age of 37.8 years. At diagnosis, only 54/171 (31.6%) were receiving HAART, and CD4+ T-lymphocyte counts ranged from 4 to 264 cells/upsilon...

This study analyzed the RYP1 gene as a target for the molecular diagnosis of histoplasmosis. This assay detected fungal DNA in 13/13 blood samples from HIV/AIDS-patients with histoplasmosis. Therefore, the detection of RYP1 gene in whole blood sample is a quick and sensitive test to diagnose histoplasmosis.

We present the case of a 34 year-old man, HIV-positive, who had suffered a disseminated histoplasmosis treated with amphotericin B one year before his admission. He was admitted at the Infectious Diseases Muñiz Hospital with a non-lithiasic chlolecystitis. During the clinical examination perigenital skin lesions compatible with tinea cruris, as well as proximal subungual onychomycoses of toenails, were observed. Microsporum gypseum was isolated from both types of lesions. Oral terbinafine led to a good clinical response...

The burden of histoplasmosis has been poorly documented in most of the endemic areas for the disease, including Brazil. Also, modern non-culture-based diagnostic tests are often non-available in these regions. This was a prospective cohort study in HIV-infected patients with suspected disseminated disease evaluated with different diagnostic tests. Patients were enrolled in three referral medical centres in Porto Alegre, Brazil. Among 78 evaluated patients, disseminated histoplasmosis was confirmed in eight individuals (10...

Simultaneous infections with Cryptococcus neoformans and Histoplasma capsulatum are rare and typically occur in immunocompromised individuals, particularly AIDS patients. Because both of those fungi can spur the development of latent infections, it is generally unknown which organism was first present. The diagnosis of one fungus can hide the diagnosis of the other, leading to underdiagnoses and poor prognosis. We report a case of C. neoformans and H. capsulatum co-infection. We also performed a systematic review of the literature...

Histoplasma capsulatum is no longer confined to certain geographic areas and should always be considered in the differential diagnosis of lymphadenopathy and organomegaly in HIV-positive patients. We present an unusual case of a 20-year-old immunocompromised male of African origin presenting with fever, jaundice, hepatosplenomegaly, and retroperitoneal and cervical lymphadenopathy. Fine needle aspiration (FNA) smears from the cervical lymph node revealed numerous yeast forms of histoplasma in macrophages. The patient succumbed to the fulminant infection...

INTRODUCTION: Human immunodeficiency virus (HIV) infection has become a global pandemic. Persistent generalized lymphadenopathy (PGL) is very common manifestation of HIV infection. Moreover, different opportunistic infections such as tuberculosis (TB) and malignancies may present with lymphadenopathy. Mycobacterium avium complex (MAC) infection is most common with cluster of differentiation (CD)4+ count ≤50 cells/μL. Fine-needle aspiration cytology (FNAC) offers a simple and effective modality for obtaining a representative sample of the material from lymph nodes, permitting cytological evaluation and other investigations...
