Amphotericin B (Fungizone)
Amphotericin B is the drug of choice for overwhelming acute pulmonary histoplasmosis, chronic pulmonary histoplasmosis, all forms of progressive disseminated histoplasmosis, meningitis, and endovascular histoplasmosis.

Medication

Itraconazole is one type of antifungal medication that’s commonly used to treat histoplasmosis. 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.

Procedures

The 3 most common serologic assays for histoplasmosis include the immunodiffusion (ID) test, complement fixation (CF) test, and enzyme immunoassay (EIA).

Nutrition

Positive cultures provide the strongest evidence for histoplasmosis, but culture diagnosis has significant limitations. In particular, most patients with an asymptomatic or a mild form have negative cultures (Table 2). Non-culture methods have been developed to improve the rate and speed of diagnosis.

What is the drug of choice for histoplasmosis?

Itraconazole is one type of antifungal medication that's commonly used to treat histoplasmosis. 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.

What is considered to be the gold standard for the diagnosis of histoplasmosis?

Isolation of H. capsulatum from clinical specimens remains the gold standard for the diagnosis of histoplasmosis.

What are the treatment for histoplasmosis?

Severe infections or disseminated cases of histoplasmosis require treatment with antifungal medications. Itraconazole (Sporanox, Onmel), fluconazole (Diflucan), and amphotericin B (Ambisome, Amphotec; drug of choice for severe disease) are antifungal drugs that treat histoplasmosis.

Should histoplasmosis be treated?

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 form of the disease, you'll likely need treatment with one or more antifungal drugs.

What is Histoplasma antibody?

The histoplasma antibody immunodiffusion test is used for the in vitro determination of precipitating antibodies to Histoplasma sp. It is also used as an aid in the diagnosis of Histoplasmosis. This test detects the presence of two significant precipitin bands.

How do you treat histoplasmosis naturally?

The following supplements may help reduce symptoms of histoplasmosis or improve the immune system, although there isn't any scientific evidence for their effectiveness:Vitamin C. ... Grapefruit seed extract (Citrus paradisi). ... Probiotic supplement (containing Lactobacillus acidophilus) may improve immune system function.More items...

What is the best medicine for histoplasmosis?

Amphotericin B (Fungizone) Amphotericin B is the drug of choice for overwhelming acute pulmonary histoplasmosis, chronic pulmonary histoplasmosis, all forms of progressive disseminated histoplasmosis, meningitis, and endovascular histoplasmosis.

Does fluconazole treat histoplasmosis?

Fluconazole is a broad-spectrum triazole antifungal drug that possesses in vitro activity against Histoplasma capsulatum and has been effective in both immunocompetent and immunosup- pressed murine models of histoplasmosis [9-11] .

How does itraconazole work?

Itraconazole tablet is only used to treat onychomycosis of the toenails. This medicine works by killing the fungus or yeast and preventing its growth. This medicine is available only with your doctor's prescription.

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 key to confirming histoplasmosis?

Histoplasmosis is usually diagnosed with a blood test or a urine test. Healthcare providers rely on your medical and travel history, symptoms, physical examinations, and laboratory tests to diagnose histoplasmosis.

Is there a vaccine for histoplasmosis?

There is no vaccine to prevent histoplasmosis, and it is not always possible to prevent exposure to the fungus in areas where the fungus is common in the environment. People should avoid areas with accumulations of bird or bat droppings, especially if they have weakened immune systems.

How long do you have to take antifungal medication for histoplasmosis?

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 form of the disease, you'll likely need treatment with one or more antifungal drugs. If you have a severe form of the disease, you might need to continue to take medications for three months ...

Is it necessary to test for histoplasmosis?

While testing might not be necessary for mild cases of histoplasmosis, it can be crucial in treating life-threatening cases.

What is the best treatment for histoplasmosis?

Options for therapy include amphotericin B or one of its lipid formulations, and ketoconazole, itraconazole, or fluconazole. Recently, newer antifungal agents have been evaluated in animals models of histoplasmosis. Of these, a new triazole, posaconazole (SCH56592) appears most promising.

What is the causative organism of histoplasmosis?

The causative organism is a dimorphic fungus, Histoplasma capsulatum. Histoplasmosis can present as a self-limited disease or cause life-threatening diseases resulting in considerable morbidity and mortality.

Is itraconazole used for severe histoplasmosis?

The role of intravenous formulation of itrac onazole for severe histoplasmosis is unknown because studies comparing it with amphotericin B have not been conducted. Copyright 2001 by W.B. Saunders Company.

Abstract

Early diagnosis of histoplasmosis is essential to establish a suitable antifungal therapy and reduce morbidity and mortality rates. However, laboratory diagnosis remains challenging due to the low availability of proper methods and the lack of clinical suspicion. Conventional diagnosis is still largely used even though limitations are well known.

1. Introduction

Histoplasmosis is caused by the thermally dimorphic fungi Histoplasma capsulatum and encompasses a broad variety of clinical presentations ranging from asymptomatic infections to subacute, acute and chronic pulmonary infections [ 1 ].

2. Conventional diagnostic methods

Conventional diagnostic methods are still widely used for the diagnosis of histoplasmosis. The definite diagnosis is based on the isolation of the fungus in culture or the visualization of intracellular yeasts in tissues or other clinical samples.

3. Antigen detection

The detection of H. capsulatum antigens in clinical samples represented a breakthrough in the early diagnosis of histoplasmosis and has been included in the EORTC/MSG criteria for diagnosis of IFIs for almost 20 years [ 13, 22, 23 ]. The H.

4. Antibody detection

The main advantages of antibody detection tests are the requirement of minimally invasive samples and the achievement of results when culture is still negative reducing the need of handling potentially infectious fungi [ 36 ].

5. DNA based detection methods

PCR methods based on the detection of fungal DNA directly from clinical samples are currently implemented in the routine of several laboratories for the diagnosis of main fungal infections, but there are considerably fewer PCR tests for the diagnosis of histoplasmosis.

6. Conclusions and future perspectives

Early diagnosis of histoplasmosis is essential to establish a suitable antifungal therapy, which results in the reduction of mortality rates [ 55, 56 ]. This becomes especially important in certain hyper-endemic regions since they usually are disfavored areas where patients develop the disease in its disseminated form.
