If untreated, disseminated histoplasmosis is usually fatal 37). Disseminated histoplasmosis presents with a febrile illness that can be complicated by severe sepsis, acute respiratory distress syndrome, and disseminated intravascular coagulopathy.
Procedures
Abstract Disseminated histoplasmosis is a relentlessly progressive granulomatous disease which can mimic many other granulomatous diseases including tuberculosis. A 48-year-old male was referred to us with 11 months history of multiple subcutaneous swellings and ulcerations over the upper and lower limbs and fever for 2 months.
Nutrition
Treatment usually isn't necessary if you have a mild case of histoplasmosis. But if your symptoms are severe or if you have the chronic or disseminated forms of the disease, you'll likely need treatment with one or more antifungal drugs.
What is the prognosis of histoplasmosis?
This case confirms the importance of considering fungal infections as a possibility while treating disseminated granulomatous infections, even in immune-competent patients, especially if response to treatment is inadequate.

What is disseminated histoplasmosis?
What are the treatment options for histoplasmosis?
Should fungal infections be considered when treating disseminated histoplasmosis in immune-competent patients?
How long can you live with disseminated histoplasmosis?
Disseminated histoplasmosis manifests most prominently in the digestive tract, from mouth to anus, beside its well-described symptoms and manifestations, such as pulmonary disease, skin lesions, fever, and encephalopathy [3]. Untreated disseminated histoplasmosis usually leads to death within a few weeks.
Can disseminated histoplasmosis be cured?
For some people, the symptoms of histoplasmosis will go away without treatment. However, prescription antifungal medication is needed to treat severe histoplasmosis in the lungs, chronic histoplasmosis, and infections that have spread from the lungs to other parts of the body (disseminated histoplasmosis).
What is the prognosis of histoplasmosis?
If untreated, subacute progressive disseminated histoplasmosis results in death within 2-24 months. A relapse rate of 50% is associated with acute progressive disseminated histoplasmosis, if treated. The rate decreases to 10-20% with life-long antifungal maintenance. Death is imminent without treatment.
How serious is disseminated histoplasmosis?
Severe histoplasmosis Called disseminated histoplasmosis, it can affect nearly any part of your body, including your mouth, liver, central nervous system, skin and adrenal glands. If untreated, disseminated histoplasmosis is usually fatal.
How long does it take to heal histoplasmosis in your lungs?
For most people, the symptoms of histoplasmosis will go away within a few weeks to a month. However, some people have symptoms that last longer than this, especially if the infection becomes severe.
What is the gold standard for treatment of histoplasmosis?
Itraconazole is an effective treatment in mild or moderate cases of disseminated histoplasmosis, as well as in acute and chronic pulmonary disease. Although itraconazole is not as rapid-acting as amphotericin, it has the advantage of being well tolerated even in long-term use.
What is progressive disseminated histoplasmosis?
Histoplasmosis is an infection caused by inhaling a fungus called Histoplasma. The most severe form of histoplasmosis is called progressive disseminated histoplasmosis, in which the infection spreads from the lungs to other organs. It is life‐threatening for people with advanced HIV.

A 48-year-old male was referred to us with 11 months history of multiple subcutaneous swellings and ulcerations over the upper and lower limbs and fever for 2 months.
Is disseminated valley fever curable?
Mild cases of valley fever usually resolve on their own. In more-severe cases, doctors treat the infection with antifungal medications.
What are the symptoms of disseminated histoplasmosis?
In most cases, histoplasmosis causes mild flu-like symptoms that appear between 3 and 17 days after exposure to the fungus. These symptoms include fever, chills, headache, muscle aches, cough and chest discomfort.
What causes disseminated histoplasmosis?
Histoplasmosis is an infection caused by a fungus called Histoplasma. The fungus lives in the environment, particularly in soil that contains large amounts of bird or bat droppings.
Is there a cure for ocular histoplasmosis?
What Treatment Is Available for Ocular Histoplasmosis? There are no eye drops or antibiotics known to be effective in ocular histoplasmosis. Most cases of ocular histoplasmosis are treated with medications known as antibodies to vascular endothelial growth factor (Anti-VEGF).
What is the best medication for histoplasmosis?
However, prescription antifungal medication is needed to treat severe histoplasmosis in the lungs, chronic histoplasmosis, and infections that have spread from the lungs to other parts of the body (disseminated histoplasmosis). Itraconazole is one type of antifungal medication that’s commonly used to treat histoplasmosis.
How long does it take for itraconazole to work?
Depending on the severity of the infection and the person’s immune status, the course of treatment can range from 3 months to 1 year.
How to diagnose ocular histoplasmosis?
An eye care professional will usually diagnose ocular histoplasmosis syndrome if a careful eye examination reveals two conditions: (1) The presence of histo spots, which indicate previous exposure to the histo fungus spores; and (2) Swelling of the retina, which signals the growth of new, abnormal blood vessels. To confirm the diagnosis, a dilated eye examination must be performed. This means that the pupils are enlarged temporarily with special drops, allowing the eye care professional to better examine the retina.
What is the cause of vision loss in the US?
Histoplasmosis, even mild cases, can later cause a serious eye disease called ocular histoplasmosis syndrome, a leading cause of vision loss in Americans ages 20 to 40. Ocular histoplasmosis syndrome is a clinical entity that is characterized by small, round, discrete, macular or mid peripheral atrophic (punched out) chorioretinal lesions (histo spots), peripapillary scarring, choroidal neovascularization and the absence of anterior uveitis and vitritis 30). Diagnosis of this disorder is based upon characteristic clinical findings and a positive histoplasmin skin test or residence in an endemic region for Histoplasma capsulatum. There is no active systemic disease during diagnosis of ocular histoplasmosis syndrome . Disciform scarring and macular choroidal neovascularization secondary to ocular histoplasmosis syndrome is a well-known complication which leads to loss of visual acuity or visual disturbance. Without therapy, the visual prognosis in these patients is unfavorable. Submacular surgery, radiation, steroids, photodynamic therapy, and most recently anti-vascular endothelial growth factor therapy are current therapeutic options for this condition.
What causes skin lesions of histoplasmosis?
Skin lesions of histoplasmosis are varied and can be caused by an immune reaction to an acute pulmonary infection (the lesions do not have the fungus in them) or as a manifestation of disseminated histoplasmosis (the lesions are infected). Cutaneous manifestations are reported to occur in 10% to 25% of AIDS patients with disseminated histoplasmosis.
Where does histoplasmosis occur?
Histoplasmosis is a common disease throughout the world, occurring in temperate and tropical climates such as parts of the USA, Africa and Australasia. In the United States, Histoplasma mainly lives in the central and eastern states, the region often referred to as the “Histo Belt”, includes Arkansas, Kentucky, Tennessee, West Virginia as well as other areas of southeastern and central US, especially areas around the Ohio and Mississippi River valleys 5). The Histoplasma capsulatum fungus also lives in parts of Central and South America 6), Africa 7), Asia 8), and Australia 9). In certain areas up to 90% of the adult population are infected with histoplasmosis 10), 11).
How to test for histoplasmosis?
The most common way that healthcare providers test for histoplasmosis is by taking a blood sample or a urine sample and sending it to a laboratory.
Does ocular histoplasmosis cause scars?
Ocular histoplasmosis syndrome usually has no symptoms in its early stages; the initial ocular histoplasmosis syndrome infection usually subsides without the need for treatment. This is true for other Histoplasma fungus infections; in fact, often the only evidence that the inflammation ever occurred are tiny scars called “histo spots,” which remain at the infection sites. Histo spots do not generally affect vision, but for reasons that are still not well understood, they can result in complications years–sometimes even decades–after the original eye infection. Histo spots have been associated with the growth of the abnormal blood vessels underneath the retina.
Can you get histoplasmosis again?
It’s possible for someone who’s already had histoplasmosis to get it again, but the body’s immune system usually provides some partial protection so that the infection is less severe the second time. In people who have weakened immune systems, histoplasmosis can remain hidden in the body for months or years and then cause symptoms later (also called a relapse of infection) 26).
How long does it take for histoplasmosis to go away?
How Histoplasmosis Is Treated. Most cases of histoplasmosis go away on their own in a few weeks without treatment. However, for chronic or disseminated histoplasmosis, antifungal medication is recommended.
How to contact lung helpline?
Finding Support. To talk to a trained respiratory professional who can help answer your questions and connect you with additional support, call the Lung Association 's Lung HelpLine at 1-800-LUNGUSA.
Is histoplasmosis a long term disease?
For most people, there are no long-term consequences of histoplasmosis. Reoccurrence is possible, however, especially for people with weakened immune systems. So, it is important to take precautions to avoid infection in the future.
What is histoplasmosis caused by?
Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. This disease is highly endemic in some regions of North America, Central America, and South America and is also reported in certain countries of Asia and Africa. It often affects people with impaired immunity, including people living with HIV, among whom the most frequent clinical presentation is disseminated histoplasmosis. The symptoms of disseminated histoplasmosis are non-specific and may be indistinguishable from those of other infectious diseases, especially disseminated tuberculosis (TB), thus complicating diagnosis and treatment. Histoplasmosis is one of the most frequent opportunistic infections caused by fungal pathogens among people living with HIV in the Americas and may be responsible for 5–15% of AIDS-related deaths every year in this Region.
