Overview
While cryptococccus and candida infections occur worldwide, other fungal infections tend to cluster in specific geographical regions.[1][2] The most common cause of fungal meningitis is Cryptococcus neoformans.[3][4][2]
Epidemiology
Incidence and prevalence
There is an increasing trend of fungal meningitis. This has been attributed to the following: [2][5]
- Enlarging population of high-risk immunosuppressed patients
- More successful pharmacological immunosuppression and chemotherapies
- Increase in numbers of patients living with human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome (AIDS)
- Migration of susceptible persons into hyperendemic areas
- Aging of the population
Cryptococcus Meningitis
- It is the most common cause of fungal meningitis.[6][4][2]
- Cryptococcus meningitis occurs worldwide but it is highly prevalent in southeast Asia and southern and east Africa where the prevalence of HIV is high.[7]
- It is a common opportunistic infection in patients with HIV and it is considered as an AIDS defining lesion. [8]
Rates of cryptococcosis in non-HIV-infected individuals approach one case per 100,000 population and are comparable to incidence rates of meningococcal meningitis.[9]
During the AIDS epidemic before highly active antiretroviral therapy (HAART) in the United States, cities such as Atlanta, Georgia were reporting annual rates of cryptococcosis as high as 66 cases per 1,000 persons with AIDS[10]
During the era of HAART, this figure of disease has been reduced [11]
but not eliminated, and without HAART, the high infection rates persist and the natural history of untreated infection can still be traced.[12]
By 2009, the Centers for Disease Control and Prevention estimated that worldwide, there are 1 million new cases of cryptococcosis per year with over 600,000 deaths, making it the most common invasive fungal infection in the world today.[13]
This species is predominantly found in clinical infections from Australia, Southeast Asia, and Central Africa; however, an infection outbreak with C. gattii more recently has emerged in Vancouver, Canada and the Pacific Northwestern United States[14][15]
Histoplasma meningitis
incidence rates in 1976 ranged from 23.0 per million for histoplasmosis to 0.2 per million for blastomycosis.[5]
Coccidioido meningitis
- Coccidioidomycosis is only prevalent in the Western Hemisphere, especially in the southwestern United States and northwestern Mexico.
- The annual incidence of the disease is not known.
Age
Gender
Race
- Non-Caucasian race have a higher prediclection to developing fungal meningitis especially coccidioidal meningitis[16]
Developed Vs developing countries
Geographic Distribution of Endemic Fungi in The United States
- Blastomyces dermatiditis: Midwest and southeast of USA
- Coccidiodes immitis: Southwest of USA
- Histoplasma Capsulatum: Ohio, central Mississippi River Valley[17]
