Extractions: (Systemic Mycoses) Topics [General] Histoplasmosis Coccidioidomycosis Blastomycosis ... Other Fungal Opportunists Histoplasmosis A disease caused by Histoplasma capsulatum, causing primary pulmonary lesions and hematogenous dissemination. Histoplasmosis occurs worldwide. The endemic areas in the USA are in the Ohio-Mississippi river valleys extending into parts of northern Maryland, southern Pennsylvania, central New York, and Texas, but microfoci have been noted in other states, such as Florida. H. capsulatum Symptoms and Signs The disease has three main forms. Acute primary histoplasmosis is usually asymptomatic. If symptoms develop, they are usually nonspecific, with fever, cough, and malaise of varying severity. Acute pneumonia sometimes is evident on physical examination and chest x-ray. Progressive disseminated histoplasmosis follows hematogenous spread from the lungs that is not controlled by normal cell-mediated host defense mechanisms. Characteristically, generalized involvement of the reticuloendothelial system, with hepatosplenomegaly, lymphadenopathy, bone marrow involvement, and sometimes oral or GI ulcerations occurs, particularly in chronic cases. In general, the course is usually subacute or chronic, with only nonspecific, often subtle symptoms such as fatigue, weakness, malaise, or, in HIV-positive patients, an unexplained worsening in condition. Addison's disease is an uncommon but potentially serious manifestation and must be distinguished from other causes of adrenal insufficiency such as TB, sarcoidosis, lymphoma, or leukemia. Severe manifestations occur most often in infants and immunocompromised patients.

Extractions: Histo the short name for histoplasmosis is a deceiver. It used to be thought rare. Only 71 cases were known to doctors in the United States up to 1945. Today an estimated fifty million Americans are believed to have been infected with it. Histoplasmosis used to be considered a fatal disease. Today, among the millions infected, there are very few fatalities. Histoplasmosis is a masquerader. The "summer flu" that Midwesterners used to get often is now thought to he been histoplasmosis. The disease is not "catching" from someone who has it, as tuberculosis is but many times it has been mistaken for TB, as well as other diseases. What Causes Histoplasmosis? Histoplasmosis is caused by a fungus (mold), an extremely simple form of plant life. (Other familiar fungi are mushrooms, yeast and mildew.) The particular fungus, or plantæ, that causes this disease is known as histoplasmosisplasma capsulatum. It is tiny and light enough toloat in the air when stirred up with dust. Once it is breathed in, the fungus gets down into the lungs. In effect, it takes root there like a seed and continues to live. The tiny plants increase in number within the lungs simply by dividing themselves in two over and over again.

Extractions: Overview Histoplasmosis is caused by a fungus commonly found in the dust and soil of the Mississippi-Ohio River Valley region. Approximately 62% of the adult population living in this region are carriers. It affects men and women equally. Histoplasmosis is contracted by inhaling dust that carries the fungal spores. Its effect on the body can vary widely in severity from one person to another. Many carriers have no symptoms at all, but those with mild exposure may experience flu-like symptoms and mild respiratory infections. Histoplasmosis is more likely to become a serious problem in people who already have a weakened immune system. The fungus may affect the eye by causing small areas of inflammation and scarring of the retina These are called histo spots and may be found in both eyes.

Extractions: RETURN TO INDEX SPANISH TRANSLATION Histoplasmosis ("Histo") What is histoplasmosis? Histoplasmosis (also known as "histo") is an infection caused by the fungus Histoplasma capsulatum . This organism lives in the soil of the central United States (Ohio and Mississippi river valleys), the Caribbean region, and Central and South America. Histoplasmosis is most often a mild illness, but it can be a serious infection in people with impaired immune function. How does it cause disease? Histoplasma organisms are found in soil in the form of microscopic particles called spores. Primary infection occurs when dust is stirred up. Spores get into the air and are inhaled and lodge in the lungs. The severity of primary infection depends on the number of inhaled spores and strength of the immune system. Fortunately, the organism does not spread from person to person, so you cannot catch histoplasmosis from someone else. Generally, spores from the primary infection are walled off in the lungs and remain inactive. However, if the immune system weakens, spores can grow and cause disease in the lungs or elsewhere. If infection spreads throughout the body, the condition is called

Extractions: What is histoplasmosis? Histoplasmosis is an infection caused by the fungus Histoplasma capsulatum . The ymptoms vary greatly but it primarily affects the lungs. It rarely invades other parts of the body. Who gets histoplasmosis? Anyone can get histoplasmosis. Positive histoplasmosis skin tests are seen in as many as 80% of people living in some areas of the eastern and central United States, although most of these people never show any symptoms. It is often called the "cave sickness" as it is sometimes seen in persons who explore caves for a hobby. The more severe forms of this disease are seen more frequently in persons who have problems with their immune systems, such as persons with AIDS. Bats, dogs, cats, rats, skunks, opossum, foxes and other animals can get histoplasmosis and may play a role in spreading the disease. How is this fungus spread? The fungus grows in soil enriched with bat or bird (especially chicken) droppings that have gathered for three or more years. The fungus produces spores that get into the air if the contaminated soil is disturbed. Breathing in these spores causes infection. You cannot get histoplasmosis from another person.

In the United States, it is most common in the southeastern, mid-Atlantic, and central states. The lungs are the portal of entry for this infection. Histoplasma grows as a mold in soil and infection results from inhalation of airborne fungal particles. Soil contaminated with bird or bat droppings may have a higher concentration of mold. Histoplasmosis may have no symptoms, there may be a short period of active infection or it can become chronic and spread throughout the body. Most patients with symptomatic histoplasmosis will have a flu-like syndrome and pulmonary (lung) complaints related to underlying pneumonia or other lung involvement. Individuals with chronic lung disease (e.g., emphysema bronchiectasis ) may be at higher risk of a more severe infection.

En los Estados Unidos esta infección es más común en los estados del sudeste, de la zona atlántica media y en los estados centrales. Los pulmones son el portal de entrada para esta infección. El histoplasma crece como un moho en el suelo y la infección es ocasionada por la inhalación de partículas micóticas transportadas por el aire. El suelo contaminado con los excrementos de aves o de murciélagos puede tener mayores concentraciones de moho. La histoplasmosis puede ser asintomática; es posible que se presente un corto período de infección activa o que ésta se disemine por todo el cuerpo. La mayoría de los pacientes con histoplasmosis sintomática desarrollan un síndrome similar al de la influenza y enfermedades pulmonares relacionadas con una neumonía subyacente o con otro compromiso pulmonar. Las personas con enfermedad pulmonar crónica, como el enfisema o la bronquiectasia, pueden tener un riesgo mayor de ser atacados por una presentación más severa de esta enfermedad.

Extractions: HISTOPLASMOSIS What is histoplasmosis? Histoplasmosis is an infectious disease caused by inhaling spores of a fungus called Histoplasma capsulatum Who gets histoplasmosis? Anyone who is present near dust-producing activities where material contaminated with H. capsulatum becomes airborne can get histoplasmosis if enough spores are inhaled. Infants, young children, and older persons, in particular those with chronic lung disease, are at increased risk for developing symptomatic histoplasmosis. People with weakened immune systems are at greatest risk for developing severe and disseminated disease. H. capsulatum grows in soil throughout the world. In the United States, it is more common in the central and eastern states, especially along the valleys of the Ohio, Mississippi, St. Lawrence rivers, and the Rio Grande. The fungus seems to grow best in soils with a high nitrogen content, especially those contaminated with bird manure or bat droppings. How is histoplasmosis spread?

Histoplasmosis is an infection caused by a fungus. It is commonly found in the soil in parts of the Midwestern United States, Haiti and in the southern parts of Ontario and Quebec where there is contamination with bird and bat droppings. This may include buildings where birds and bats nest. It is relatively rare in most other parts of Canada. This fungus enters the body most commonly through the lungs (breathing in particles of the contaminated soil). It can be in your body for several years and then start to cause symptoms as the immune system weakens. Symptoms of Histoplasmosis do not usually appear until the CD4 counts have dropped below 100. It is not contagious from one person to another. What do I look for?

Extractions: HISTOPLASMOSIS What is histoplasmosis? Histoplasmosis is an infection caused by a fungus, Histoplasma capsulatum . The principal habitat for this fungus is soil enriched by bird droppings and in bat droppings. In the United States, the fungus is found most often along the Mississippi and Ohio river valleys, but also is present in other central, southeastern and mid-Atlantic states. In people, it affects the lungs and may occasionally invade other parts of the body. It is an uncommon disease with generally fewer than 50 human cases reported in Illinois each year. Dogs, cats, rats, skunks, opossum, foxes and other animals also can get histoplasmosis. Who gets histoplasmosis? Anyone can get histoplasmosis. In some areas where the fungus is prevalent, 80 percent or more of the population has been exposed to infection through breathing in airborne spores. The initial infection often occurs without causing symptoms, and most persons usually will not develop subsequent disease, unless the exposure was heavy. Long-term smokers and those with preexisting lung disease may be at higher risk for developing the disease.

Extractions: Maculopathy The Common Visual Problems of Ocular Histoplasmosis Syndrome Richard L. Windsor, O.D., F.A.A.O. Laura K. Windsor, O.D. Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum . This fungus is found throughout the world, but is endemic in the Mississippi and Ohio River Valley areas in the United States. This fungus is found in soil where bird and bat droppings have accumulated including chicken coops, caves and in old buildings. People who live or work on farms, landscapers, construction workers, and others who work outdoors can be exposed. The fungal spores become airborne when the soil is disrupted and are inhaled into the lungs. It usually produces only mild flu or cold like symptoms, so the person may be totally unaware that he or she has been exposed to Histoplasmosis. In older patients OHS may occasionally be misdiagnosed as macular degeneration. However even though the systemic symptoms are mild, it can cause serious retinal condition called Ocular Histoplasmosis Syndrome (OHS). OHS is a leading cause of blindness in the 20 to 40 year old age group and affects men and women equally. Most people with OHS are unaware that they even have any retinal signs and approximately 5% of people with OHS are at risk for having severe vision loss. The Initial Infection: The fungus, after being inhaled, travels through the blood vessels into the eyes where it can cause inflammation and scarring in the peripheral retina. These scars usually do not cause visual problems and are called histo spots. Histo spots vary in number, but can usually be seen in both eyes.

http://users.skynet.be/sky33676/histo.html

Extractions: The growing conditions for the fungus are warmth (more than 20 - 24 °C), moisture and soils with lots of humus and animal excrement (especially the excrement of bats and blackbirds). That's why the thick layers of guano in the Jamaican bat caves are an ideal breeding ground for this fungus. Other high-risk zones are old chicken houses, barns, belfries, pigeon lofts,... anywhere that there is soil with an accumulation of bat and/or bird excrement.
