What is invasive candidiasis?

Medical illustration of Candida albicans.

Invasive candidiasis is an infection caused by a yeast (a type of fungus) called Candida.  Unlike Candida infections in the mouth and throat (also called “thrush”) or vaginal “yeast infections,” which are localized to one part of the body,  invasive candidiasis is a serious infection that can affect the blood, heart, brain, eyes, bones, or other parts of the body.¹

Candida normally lives inside the body (in places such as the mouth, throat, gut, and vagina) and on the skin without causing any problems.² However, in certain patients who are at risk, Candida can enter the bloodstream or internal organs and cause an infection. A Candida bloodstream infection, also called candidemia, is the most common form of invasive candidiasis. ¹ In the United States, candidemia is one of the most common causes of bloodstream infections in hospitalized patients,^3–4 and it often results in long hospital stays and death. It is also responsible for high medical costs.⁵

Antifungal medication can treat invasive candidiasis. Certain patients such as those with cancer or bone marrow or organ transplants might receive antifungal medication to prevent invasive candidiasis.⁶

Where Invasive Candidiasis Comes From | Invasive Candidiasis | Candidiasis | Types of Diseases | Fungal Diseases

Candida lives in and on the body

Candida, the fungus that causes invasive candidiasis, normally lives inside the body (in places such as the mouth, throat, gut, and vagina) and on the skin without causing any problems.¹ In some people who are at higher risk for the infection, Candida can enter the bloodstream or internal organs and cause invasive candidiasis. For example, this can happen when a central venous catheter is inserted and left in place for a long time, during surgery, or when the immune system is weakened during chemotherapy. Healthcare workers can also carry Candida on their hands. ^2,3 A few outbreaks of candidemia have been linked to healthcare workers’ hands,^4,5 so hand hygiene in healthcare settings is important for preventing the spread of infections.

Types of

Candida

There are over hundreds of species of Candida, but only a few are known to cause infections.⁶ The most common species that cause infections are C. albicans, C. glabrata, C. parapsilosis, C. tropicalis, and C. krusei.

Another species called C. auris is emerging as a cause of invasive candidiasis around the world and in certain areas of the United States – read more about this concerning and often drug-resistant species.

Thrush in women – symptoms and treatment in St. Petersburg

How the disease develops: causes and pathogenesis

Normally, the mucous membrane of the external genitalia is not sterile. The microflora of the vagina includes friendly microorganisms, including the Candida fungus, which serve as the body’s defense against infection. Under adverse conditions, when the microbiome is disturbed, the fungus spreads rapidly, causing the characteristic symptoms of thrush. In some cases, the underlying tissues and blood vessels are also involved in the pathological process, which carry the fungus throughout the body.

The causes of thrush in women are varied:

• Taking medications – antibacterial drugs, cytostatics, glucocorticosteroids, immunosuppressants.

• Decrease in general immunity against the background of chronic diseases – diabetes mellitus, pyelonephritis, blood diseases, tonsillitis, metabolic disorders.

• Changes in the hormonal background due to pathologies of the female genital area, pregnancy, hypothyroidism, the use of oral contraceptives.

• Stress factors – climate change, nervous tension, physical and emotional overload.

• Errors in matters of personal hygiene – untimely change of pads and tampons, the use of aggressive cleansers (violate the natural pH level of the vagina).

• The presence of injuries of the mucous membrane, provoked by wearing tight underwear, sexual intercourse with a deficiency of natural lubrication.

Often, a decrease in local immunity is caused by malnutrition, hypothermia, vitamin deficiency, and untreated sexually transmitted diseases.

Signs of candidiasis

Vaginal candidiasis is called “thrush” because of the characteristic cheesy discharge that accompanies the spread of fungal colonies. In some cases, the discharge may be absent or change its character depending on the phase of the menstrual cycle.

Another striking sign of candidiasis is itching and burning in the intimate area. Itchy sensations are so unbearable that they significantly worsen the quality of life of a woman. Itching increases in the morning, before menstruation, after hygiene procedures and sexual intercourse.

Other symptoms of thrush:

• burning and pain during urination;

• soreness during intimate contacts;

• pungent sour smell of discharge.

If the disease becomes chronic, relapses of fungal infections of the external genital organs occur more often than four times a year. Recurrent candidiasis has an erased clinical picture, when signs of pathology are present, but weakly expressed.

With complicated thrush, the pathological process is more difficult. Deeper tissues are affected, ulcerations and cracks are observed on the vaginal mucosa.

How candidiasis is diagnosed

The treatment of vaginal candidiasis is preceded by a comprehensive diagnosis. The disease in women can be diagnosed already during the initial gynecological examination. The mucous membrane of the vagina looks edematous and inflamed. The natural pink color of the fabrics changes to bright scarlet. Specific discharges of white or yellowish color with grains resembling cottage cheese are found.

With a complicated fungal infection, vesicles appear on the skin of the external genital organs. These are small blisters filled with a cloudy or clear liquid. They are able to open, exposing the epidermis and provoking the development of erosion.

To confirm the diagnosis, medical laboratory tests are carried out:

• smear microscopy – examination of the microflora of the vagina under a microscope;

• bakposev secretions – allows you to accurately detect the fungus-causative agent;

• PCR and ELISA of genital secretions for the detection of Candida albicans antigens;

• complete blood count – helps to see the inflammatory process.

Diagnosis is complicated if thrush occurs against the background of sexually transmitted diseases – chlamydia, gonorrhea, trichomoniasis. Therefore, an accurate diagnosis and development of a treatment plan for candidiasis in women is the prerogative of a doctor.

Methods of treatment

It is recommended to contact the clinic at the first signs of thrush – itching and specific discharge. Self-medication can lead to the fact that the symptoms will be masked, and the fungal disease will become recurrent. Dealing with it will be much more difficult, and the likelihood of complications will only increase.

Treatment methods for thrush will include both medications and medications aimed at normalizing the microflora. Doctors mainly focus on antifungal medications containing nystatitis, fluconazole, clotrimazole, nitrofungin, ketoconazole. They disrupt the synthesis of substances contained in the membrane of the fungus, which inhibits the growth of colonies or leads to the complete destruction of the pathogen. Preparations for candidal lesions of the mucous membranes are available in the form of tablets, capsules, suppositories, ointments and creams. The drug is selected individually, taking into account the clinical picture.

The program of complex treatment of candidiasis also includes:

It is important to eliminate the cause of the pathology in order to prevent the occurrence of relapses. Funds may be required to improve hormonal levels, fight dysbacteriosis and sexually transmitted diseases.

It is recommended to adjust the diet – reduce the consumption of sweets and carbohydrates. They serve as a breeding ground for the active development of the fungus and slow down recovery.

Of the physiotherapeutic methods for the treatment of thrush, darsonvalization, laser therapy, electrophoresis, and magnetotherapy contribute. During therapy and after it, it is necessary to adhere to the basic principles for the prevention of microflora disorders:

• abandon tight synthetic underwear in favor of comfortable cotton;

• timely treat common diseases – hormonal, inflammatory, infectious;

• change tampons and pads more often during menstruation;

• refuse “daily”;

• do not take antibiotics without a doctor’s prescription;

• use special means for intimate hygiene;

• when carrying out antibacterial therapy, in parallel, use means to restore normal microflora.

Do not treat candidiasis as a harmless disease. The inflammatory process caused by the fungus can spread to surrounding organs and tissues. Against the background of weakened immunity, a bacterial infection easily joins a fungal infection, which is fraught with the development of salpingitis, adnexitis, urethritis, cystitis. Only competent treatment of thrush in the clinic “MEDIONA PARNAS” is the key to a successful recovery and preservation of women’s health.

1. What is candidiasis, oral candidiasis

Candidiasis, simply called thrush, is traditionally considered a vaginal disease of women, but it is not. The fungus that causes candidiasis can affect the skin, genitals, nasopharynx, and even blood.

Thrush is caused by the growth of Candida. These fungi are always present in the body, but in small quantities.

Symptoms and treatment depend on the part of the body that is affected.

Oral candidiasis

Oral candidiasis is most common in newborns, older people who have received chemotherapy, and other groups of people with weakened immune systems. It also occurs in people with diabetes or those who take antibiotics or inhalers for asthma along with steroids.

Common symptoms include:

• White patches on mouth and tongue;
• Redness or discomfort in the mouth;
• Sore throat and difficulty swallowing;
• Cracks in the corners of the mouth.

Treatment consists of taking a drug that kills the fungus. The preparation may be in the form of a tablet or rinse. In advanced cases, intravenous antifungal drugs are used.

A must to check out!
Help with treatment and hospitalization!

2. Candidiasis of the genitals in women and men

Candidiasis of the genitals, what is usually meant by thrush, is more common in women. Symptoms include:

• Vaginal irritation and redness;
• White cheesy vaginal discharge;
• Pain during sex.

Genital thrush also occurs in men. Men with circumcision are least affected by thrush. Thrush in men has the following symptoms:

• Red rash on the penis;
• Burning and itching of the head.

There are many over-the-counter remedies for genital thrush: creams, ointments, and intravaginal suppositories. There are also drugs for oral administration.
