Disseminated histoplasmosis

Radhey Shyam Chejara, C L Nawal, M K Agrawal, Pradeep Mittal, Abhishek Agrawal, Sujata Agarwal
Progressive Disseminated Histoplasmosis (PDH) is mainly described in immuno-compromised individuals and rare in immuno-competent subjects. Here we report a case of progressive disseminated histoplasmosis with Comb's positive hemolytic anemia, which is infrequently reported from a country like India where histoplasmosis is not an endemic mycosis.

Histoplasmosis is caused by a dimorphic fungus Histoplasma capsulatum in endemic areas, mainly America, Africa, and Asia. In India, it is being reported from most states; however, it is endemic along the Ganges belt. We report a case of an apparently immunocompetent male who presented with 3-month history of fever, cough, and weight loss with recent onset odynophagia and had hepatosplenomegaly and mucocutaneous lesions over the face. The differential diagnosis of leishmaniasis, tuberculosis, leprosy, fungal infection, lymphoproliferative malignancy, and other granulomatous disorders was considered, but he succumbed to his illness...

Severe pulmonary or disseminated histoplasmosis often necessitates presumptive antifungal treatment while awaiting definitive diagnosis. Histoplasma antigen assays have improved sensitivity but results may lag up to 7 days. In order to increase diagnostic certainty, "soft clues" may be looked for in laboratory and radiologic data, such as elevated alkaline phosphatase or ferritin levels and findings of mediastinal adenopathy or hepatosplenomegaly. To determine if elevated aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio is specific to histoplasmosis or a non-specific marker for disseminated fungal infection or sepsis in general, we retrospectively examined records of all patients diagnosed with an endemic fungal infection (EFI) at Rush University Medical Center from January of 1997 to October of 2012, and a cohort of septic patients with elevated liver enzymes...

Histoplasmosis is a systemic fungal mycosis caused by Histoplasma capsulatum. It is a dimorphic fungus which lives as a saprophyte in the environment and occasionally infects immunosuppressed people. H capsulatum is a ubiquitous fungus present throughout the globe and is more common in the temperate world. Human infection with H capsulatum occurs through respiratory route by inhalation of spores present in the air as droplet nuclei. Pulmonary histoplasmosis is difficult to diagnose, more so in the regions where tuberculosis is endemic, and many infected patients remain asymptomatic...

We report two cases of chronic progressive disseminated histoplasmosis with unusual and rare clinical picture in a patient with no underlying risk factor. One 50-year-old male, presented with hoarseness of voice, chronic cough, with a history of nonresponding anti-tubercular therapy, revealed mucocutaneous lesions on examination. Fungating vocal cord lesions were visualized on bronchoscopy, raised suspicion of carcinoma. The second case, a 22-year-old female, referred to hospital with suspected vasculitis, with complaints of "off and on" fever with decreased oral intake, arthralgia, who later developed generalized nodular skin eruptions...

Histoplasmosis is a systemic mycosis that is considered an important public health problem. In this work, we performed a descriptive, observational, cross-sectional and retrospective study with a secondary data analysis of medical records from 2000 to 2012 at a tertiary hospital. The study sample consisted of 275 patients with laboratory-confirmed Disseminated Histoplasmosis (DH)/AIDS. The results showed that the prevalence of DH associated with AIDS was 4.4%. The majority of patients were young adult men with fever in 84...

Histoplasmosis is a fungal infection, having interesting synonyms such as Cave disease, Darling's disease, Ohio Valley disease, reticuloendotheliosis, Spelunker's lung and Caver's disease. The aetiological agent is a dimorphic fungus, Histoplasma capsulatum, causing chronic granulomatous disease. The route of transmission is by inhalation of dust particles from soil contaminated by excrement of birds or bats, harbouring the small spores or microconidia, which is considered the infectious form of fungus. The spectrum of illness ranges from subclinical infection of the lung to progressive disseminated disease...

CASE SERIES SUMMARY: This case series describes the clinical utility of antigen testing for the diagnosis of feline ocular histoplasmosis. Four cats with suspected (n = 2) or confirmed (n = 2) ocular histoplasmosis are described: three from Oklahoma and one from California. In one case, serial urine antigen tests, as well as a serum antigen test for Histoplasma capsulatum, were negative; however, light microscopy identified microorganisms consistent with H capsulatum in ocular tissues at necropsy...

IMPORTANCE: Disseminated histoplasmosis most commonly occurs in immunosuppressed individuals and involves the skin in approximately 6% of patients. Cutaneous histoplasmosis with an intraepithelial-predominant distribution has not been described. OBSERVATIONS: A 47-year-old man was admitted to our institution with fever and vancomycin-resistant enterococcal bacteremia. He had been diagnosed with T-cell prolymphocytic leukemia 4 years earlier and had undergone matched-unrelated-donor stem cell transplant 2 years earlier; on admission, he had relapsed disease...

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...

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...

Multiple lytic bone lesions in a child can be a manifestation of various diseases like Langerhans cell histiocytosis, metastatic neuroblastoma, leukemia, hyperparathyroidism, multifocal osteomyelitis and histoplasmosis. Disseminated histoplasmosis caused by Histoplasma capsulatum var. duboisii is well known to present with multiple osteolytic lesions in immunocompromised adults and is mostly restricted to the African subcontinent. Histoplasmosis seen in American and Asian countries is caused by Histoplasma capsulatum var...

Refractory hypoxemia secondary to acute respiratory distress syndrome (ARDS) is associated with high mortality. Extracorporeal membraneoxygenation (ECMO) is an accepted strategy for treating refractory hypoxemia in patients with ARDS but is relatively contraindicated in the setting of systemic infections. We present a case of successful ECMO use in a host with refractory hypoxemia secondary to disseminated histoplasmosis with fungemia and discuss our management approach to this difficult patient.

Neurohistoplasmosis is a rare disease, most prevalent in immunosuppressed patients, secondary to disseminated disease with a high mortality rate when diagnosis and treatment are delayed. We report a previously healthy 12 year old girl, from a bat infested region of Tucuman Province, Argentine Republic, who developed meningoencephalitis due to Histoplasma capsulatum. Eighteen months prior to admission the patient started with headaches and intermittent fever. The images of the central nervous system showed meningoencephalitis suggestive of tuberculosis...
