Yeast infection

An infection mainly caused by fungi of the genus Candida. Although members of the genus Candida continue to be the most common agents of yeast infections, numerous nosocomial (related to medical treatment) factors have altered this etiologic pattern over the last 20 years. Reports in professional publications have described over 200 species in 25 yeast genera as being associated with human infections. See Fungal infections, Fungi, Yeast

Etiologic agents

Candida, species particularly C. albicans, cause almost 70% of all yeast infections. However, recent changes in medical practices such as the use of broad-spectrum antibiotics, steroids, and immunosuppressive drugs, along with the recognition of new and highly debilitating diseases [for example, acquired immune deficiency syndrome (AIDS)], have increased the diversity of the agents of these infections. Species that were once rarely encountered in patient specimens (for example, C. parapsilosis, C. krusei, and C. guilliermondii) are being isolated with increased frequency. Equally important is the fact that yeasts that have never been described as the cause of human infections, (for example, Blastoschizomyces capitatus, C. dubliniensis, and Trichosporon cutaneum) are now being associated, albeit rarely, with human disease. See Acquired immune deficiency syndrome (AIDS), Opportunistic infections

Predisposing factors

Since yeasts are not as adept as other microbial pathogens at evading or overwhelming the body's immune defenses, they generally require some disruption in the natural protective mechanisms of humans to initiate an infection. Minor breaks in the skin (such as those caused by a cut or scrape) to more significant disruptions in the integrity of the skin (as created by the delivery of medications or nutrients through intravenous catheters) can provide the means by which the yeasts on human skin may enter the body and potentially initiate an infection. The use of broad-spectrum antibacterial agents eliminates a large portion of the normal bacterial flora, allowing the yeasts in the mouth and intestines to grow rapidly and seed the blood to create a temporary benign infection or a chronic, potentially life-threatening infection. Natural hormonal imbalances as created by pregnancy or diabetes mellitus, as well as those caused by the use of medications such as corticosteroids, depress the immune system and predispose the individual to possible yeast infections. The common use of immunosuppressive drugs, and the depressed immunity associated with newer human diseases such as AIDS cause a decrease in the immune system's ability to prevent and eliminate yeast infections. Finally, the longer human life expectancy created by modern medical practices has contributed to an ever-increasing population of senior citizens with naturally lowered resistance to all forms of microbial infections. See Immunosuppression

Clinical symptomology

Although yeast infections usually affect the skin and mucous membranes, the illness can take several different forms, each with different symptoms. For example, in newborns and infants, candidiasis can appear as reddening and blisterlike lesions of skin infections (diaper rash), or it can present as white-gray lesions on the mucosal tissue lining the oral cavity (thrush). The symptoms observed in the vast majority of yeast infections mimic those of other microbial pathogens and thus are generally of little value in establishing their etiology. The diagnosis of most yeast infections involves obtaining detailed medical histories from patients, conducting extensive physical examinations, analyzing clinical laboratory data, and utilizing the education, training, and experience of the attending physicians and infectious disease specialists. See Clinical microbiology

Treatment

The introduction of the first clinically effective antifungal antibiotic (nystatin) closely followed the use of antibacterial drugs (penicillin). However, nystatin was found to be effective only when brought into direct contact with the infectious agent. The broad-spectrum and fungicidal (killing fungi) activity of amphotericin B, another member of the same chemical family, maintains its use as the drug of choice for several yeast infections and as the antifungal of last resort when all other antibiotics have failed. Two closely related families of drugs, the azoles and triazoles, were introduced in the early 1970s and quickly established themselves as the first-line antibiotics for yeast infections. However, the newer triazoles are fungistatic (limiting growth) rather than fungicidal. As a result, recurrences of infection happen frequently once therapy is discontinued. Although new antifungal antibiotics continue to be introduced, the perfect drug with broad-spectrum and fungicidal activity, easy delivery, and limited side effects has yet to be found.

Yeast infection in bloodstream How to get rid of yeast infection systemically.A. there are several treatments and medications against systemic fungal infections, yeasts included. but in order to get treated you have to go through a proper diagnosis and a Dr. should check what kind of fungus you are having and prescribe the medication that fits it. me throwing all sort of medication names won't give you anything. this has to be checked out with a blood test and a culture.
