Candidiasis or, otherwise, thrush is an infectious disease, the main cause of which is infection with Candida fungi. These fungi belong to the same species as yeast and are part of the natural microflora of the vast majority of healthy people. The maximum concentration of these opportunistic microorganisms is observed in the intestines, nasopharynx, and vagina; Some fungi can also be found on the surface of the skin.

In a normal, healthy state of the body, the fungus does not cause any unpleasant symptoms. However, when the immune system is weakened and other provoking factors appear, Candida actively multiplies, resulting in discomfort, itching, burning and other manifestations of thrush. This disease can affect various tissues and organs; Candidiasis of the oral mucosa is also common.

Most often, infants suffer from this disease: according to statistics, up to 20 percent of children under the age of one year have suffered from candidiasis at least once. About 10 percent of people over 60 also suffer from symptoms of this infection. It occurs more often in women than in men; very often, signs of the disease appear in smokers. There are many other factors that contribute to the development of candidiasis in the mouth.

Causes of oral candidiasis

The main reason for the occurrence is a decrease in immune status, as a result of which the uncontrolled proliferation of microflora begins. Reduced immunity is observed in older people and infants, in patients suffering from HIV, AIDS and other diseases associated with immunodeficiency, in those who regularly expose the body to excessive stress, neglect the rules of a healthy diet and violate work and rest patterns. Risk factors include reasons such as:

• Use of medications.
  Taking antibiotics, immunosuppressants (drugs that suppress the immune system) and some other medications leads to disruption of the immune system and the natural balance of microflora in the body. Oral contraceptives, which affect hormonal levels, have a similar effect.
• Pregnancy.
  During pregnancy, a sharp and significant change in hormonal levels occurs, which can lead to a surge in the activity of pathogenic and opportunistic microflora.
• Radiation and chemotherapy.
  Often occurs in patients undergoing drug and radiological treatment for cancer.
• Injuries to mucous membranes.
  Violation of the integrity of the mucous membranes leads to loss or deterioration of the barrier function, as a result of which the fungus enters deep into the tissues, causing inflammation and other symptoms. Small, but constantly recurring injuries are especially dangerous - for example, when wearing incorrectly fitted dentures or braces.
• Overwork and stress.
  Prolonged stress of physical and mental forces leads to a deterioration in the protective function of the body. Similar consequences are caused by hypothermia or overheating, regular lack of sleep, insufficient, excessive or simply unbalanced nutrition, abuse of alcohol, nicotine, and narcotic substances.
• Hypo- and vitamin deficiency.
  May be caused by a lack of nutrients, in particular vitamins B and C.
• Somatic diseases.
  Frequent companions of candidiasis include tuberculosis, dysbacteriosis and other pathologies of the gastrointestinal tract, diseases of the adrenal glands and other endocrine glands. Candidiasis is a contagious disease. A large number of pathogenic microorganisms are transmitted through kissing and sexual contact, through the use of shared dishes, towels and other household items. Infection can also occur during childbirth (vertical transmission from mother to fetus). In addition, there is a risk of infection through contact with infected pets.

For the full functioning of all parts of the gastrointestinal tract, various fungi and bacteria must be present in the body.
They are called opportunistic pathogens. If their quantity corresponds to the norm, the person feels well and does not experience unpleasant symptoms of the disease. But under the influence of negative external or internal factors, bacteria and fungi can begin to actively multiply. Then their activity becomes abnormal - a disease of the oral cavity or stomach or intestines is diagnosed. It is in this scenario that candidiasis develops on the tongue, throat and cheeks. Let's look at how to treat it and what measures to take to avoid relapse after recovery.

Types of disease

The clinical picture of oral candidiasis is classified:

• For clinical and morphological.
• With the flow.
• By localization.

Clinical and morphological is divided into:

• Hyperplastic.
• Erosive-ulcerative.
• Pseudomembranous.
• Atrophic.

The clinical picture, classified according to the course, is divided into:

• Chronic.
• Spicy.

By localization:

• Cheilitis.
• Gingivitis.
• Glossitis.
• Stomatitis.
• Tonsillitis, etc.

Based on the clinical picture, oral candidiasis comes in several types:

• Chronic hyperplastic.
• Candida infection.
• Chronic atrophic.
• Acute pseudomembranous.
• Chronic pseudomembranous.
• Acute atrophic.

Lifestyle and Home Remedies for Oral Thrush

At the initial stage of candidiasis, good oral hygiene will help contain the development of the disease - brushing your teeth twice a day and at least daily use of dental floss will contribute to the timely removal of food debris and plaque from the surface of the teeth, from the interdental spaces and along the gum line. Instead of regular mouthwash, use a solution that requires a teaspoon of salt and a glass of warm water. Rinse your mouth with this solution for two minutes; After this, the solution must be spat out.

Oral candidiasis is a contagious disease that can spread to internal organs and cause serious harm to them, making it impossible for you to eat normally (if the esophagus, stomach and intestines are affected). If you suspect you have one or more of the symptoms of oral thrush, contact your dentist immediately for an accurate diagnosis. By identifying candidiasis early, your doctor can relieve symptoms and stop the infection.

Symptoms

Infection of the oral mucosa by Candida fungus can take various forms, each of which has its own characteristics of symptoms. The most common forms of the disease are candidal angulitis, glossitis, cheilitis, and stomatitis. There are both acute and chronic forms of the disease.

• Pseudomembranous acute candidiasis is the most common form and most often occurs in infants and the elderly. This form is characterized by the appearance of severe swelling and hyperemia (redness) of the mucous membranes. In addition, a characteristic whitish coating forms on the surface of the lips, palate, back of the tongue and the inside of the cheeks. If the plaque is scraped off, the surface of the mucous membrane underneath will be macerated (softened) or ulcerated and bleeding. In this case, patients complain of pain, burning or itching in the mouth; Eating becomes very difficult. Very often the process spreads to the esophagus and pharynx.
• Acute atrophic candidiasis of the oral mucosa usually develops due to the lack of adequate treatment. The upper part of the mucous membranes (epithelium) is exfoliated, the mucous membrane becomes thin, red or, on the contrary, swollen. The patient’s tongue and the corners of the lips also acquire a bright red color; the papillae on the tongue atrophy and smooth out. The plaque is absent or is found only in hard-to-reach places.
• Hyperplastic chronic candidiasis is characterized by the formation of a large number of papules and plaques of irregular or round shape. They are located close to each other on the mucous membrane of the tongue and cheeks and often become soldered and fused. Around each such formation there is a thin rim of reddened, inflamed tissue. It is difficult to scrape off or otherwise remove such a plaque. The oral cavity becomes dry and rough; When chewing, speaking, and even at rest, patients experience significant discomfort and pain. It should be noted that this disease most often affects men over 30 years of age.

The main cause of the chronic atrophic type is constant injury to the mucous membranes, for example due to wearing a prosthesis. Symptoms of the disease are localized in the affected area. Redness of the mucous membrane occurs (often along the contour of the lesion), plaque forms, pain and burning occur, and the membranes become dry.

Causes of yeast glossitis

In most cases, the disease is a consequence of a weakened immune system. Therefore, more often than others, people who have suffered some kind of serious illness encounter it. Pathology also develops due to dysbiosis resulting from long-term antibiotic therapy, taking hormones or immunosuppressants.

Other reasons include:

• ulcerative glossitis/stomatitis not treated in a timely manner;
• frequent mechanical damage to the mucous membrane covering the tongue;
• deficiency of vitamins and minerals;
• liver dysfunction;
• disruption of the normal quantitative relationship between different fractions of blood proteins;
• thyroid diseases;
• oncology;
• frequent consumption of alcoholic beverages, smoking;
• deficiency of potassium in blood plasma;
• pregnancy, breastfeeding.

Tongue candidiasis also occurs as a result of direct contact with a carrier of the infection. This refers to the transmission of the disease during kissing, when using shared utensils. In newborn children, the cause of pathology is the passage of a sick mother through the birth canal.

How does the disease manifest in children?

In children, the disease occurs in an acute form and is accompanied by the appearance of redness and swelling in the oral mucosa. The child sleeps poorly, may have no appetite, and becomes tearful.

The disease can occur in children for the following reasons:

• Weakening of the immune system.
• Infection during breastfeeding.
• Transmission of the fungus during childbirth.
• Infection through household items.

If the disease is not diagnosed and treated in a timely manner, a whitish coating resembling cottage cheese will soon appear in the child’s mouth, and in an advanced stage, ulcers will appear, which are accompanied by bleeding and cause severe pain in children.

How to recognize - main symptoms

The main symptoms of oral thrush in adults include the appearance of plaques and milky plaque in the mouth. However, signs of the disease also include:

• Feeling of discomfort in the mouth.

  If you listen to your body, you can detect the first symptoms of the disease in time. Thrush, for example, begins with itching, burning and painful sensations in areas where the mucous membrane is affected. The taste buds begin to lose sensitivity, and in the meantime, a metallic taste sometimes appears in the mouth.

• Lump in throat.

  It appears not only during times of stress, anxiety or depression. This can happen if candida fungi begin to travel and reach the larynx. The swallowing process becomes difficult and interferes with normal food intake.

• Fever.

  High temperature is a reaction to disturbances in the normal functioning of the body. In this case we are talking about the progression of the fungus.

• Bleeding.

  The mucous membrane becomes irritated and instead of healthy tissue, bleeding abrasions form.

• Mycotic seizures.

  Manifestation near the lips, namely in the corners, everything becomes red and covered with small cracks and transparent scales.

For a clear understanding of what kind of disease this is, here is a photo of thrush in the mouth in adults.

Some signs of the disease may not cause discomfort, however, this does not mean that thrush in the mouth will stop on its own. At the first symptoms, you should definitely consult a specialist and get tested.

Diagnostics

To make an accurate diagnosis, a combination of several methods is used - from a simple examination and questioning of the patient for complaints to laboratory methods, such as culture, microscopic examination of biomaterial, analysis of the degree of contamination of the oral cavity with fungal mycelium.

Oral candidiasis is accompanied by a number of characteristic external signs, in particular the formation of plaque, bad breath, ulceration and hyperemia of the mucous membranes. However, laboratory methods make it possible to accurately determine the type of pathogen and exclude the possibility of a secondary infection, which may affect the nature and duration of treatment.

Differential diagnosis is used to separate cases of candidiasis from aphthous stomatitis, leukoplakia, lichen ruber, streptococcal infection and other infectious pathologies of the oral cavity.

How to treat oral candidiasis?

Treatment is carried out using local and general, specific and symptomatic remedies. Among the main goals of therapy are the elimination of foci of infection in the oral cavity (sanitation), treatment of diseases that accompany candidiasis and are risk factors, and stimulation of the body's defenses. The total duration of treatment is usually at least 7-10 days.

As a means of local therapy, rinses are used - using solutions of boric acid, soda, sodium tetraborate. For a longer and more effective effect, such products can be used in the form of applications - moistening a cotton swab or bandage with the solution.

Nystatin for oral candidiasis is used to combat the main cause of the disease - a fungal infection. Treatment of candidiasis in the mouth may also include the use of other antimycotic (antifungal) drugs - for example, levorin ointment. The best effect is achieved by using several drugs, alternating them for several days.

Antifungal drugs are also prescribed for systemic therapy - in this case, medications for oral candidiasis and other infections such as Lamisil, Diflucan, Levarin, Nizoral, etc. are taken orally. In the most severe cases of the disease, the treatment regimen includes taking immunomodulatory drugs, as well as the use other agents that have a stimulating effect on the immune system and help strengthen the body’s own defenses.

An equally important task is to protect against additional fungal and bacterial infections that can join the Candida infection and complicate the course of the disease. For this purpose, rinses with antiseptic solutions - fucorcin, iodinol and others.

As an alternative, you can use ASEPTA antiseptic mouth rinse, which contains the active ingredients chlorhexidine and benzydamine. Both of these substances have broad antimicrobial effects. Regular use of ASEPTA rinses also has a pronounced anti-inflammatory effect and helps not only eliminate unpleasant symptoms, but also reduce the risk of complications.

Important points in the treatment of oral candidiasis -

There are several problems in treating candidiasis of any location. The first problem is that fungi of the genus Candida can be located not only on the surface of epithelial cells of the mucous membrane, but are also capable of germinating inside epithelial cells. In this case, the mucopolysaccharide membrane of the host cell will protect the fungi not only from phagocytes (which must find, absorb and digest infectious agents), but also, to a certain extent, from antifungal drugs. In this case, higher dosages of drugs and longer courses of treatment (including suppressive therapy) may be required.

Another problem may be an insufficient immune response (for example, incomplete phagocytosis of Candida fungi). In the absence of immunocorrection with the help of immunomodulators, this sharply increases the risk of developing chronic candidiasis and subsequent relapses. Among the immunomodulators, we can recommend the prescription drug "Cycloferon" (in the form of intramuscular injections), but it should be used only after the recommendation of a doctor. If a slight correction of the immune status is necessary, you can use Cycloferon tablets.

It is very important to carry out treatment while sanitation of the oral cavity, i.e. it is necessary to cure all carious teeth, foci of chronic inflammation in the oral cavity, and remove dental deposits. If soft microbial plaque and hard dental deposits have not been removed, this means that a new relapse of oral candidiasis will occur very soon. In addition, for patients with removable dentures, it is important to teach them to regularly disinfect dentures, as well as replace them if their service life has expired. It will be futile to treat oral candidiasis in patients whose dentures continue to be a source of infection.

For smokers, it is very important to reduce the frequency of nicotine consumption in this case, or better yet, give it up. If candidiasis occurs during the use of inhaled steroids (in asthmatics), the patient should be told about the need to rinse the mouth with water after spraying the steroid. During treatment, it is also very important to reduce the amount of carbohydrates consumed, and it is advisable to completely give up sweets and sugar-containing drinks. For patients with dry mouth, it is important to start using special medications to keep the oral mucosa hydrated.

Toothpastes containing lactoferrin, lactoperoxidase, lysozyme, and glucose oxidase can be of great help in the treatment and prevention of candidiasis and stomatitis. Such pastes increase local immunity in the oral cavity and reduce the risk of developing stomatitis and candidiasis. For example, such pastes are included in the SPLAT line of toothpastes.

Disease prevention

Preventive measures are aimed at improving the condition of the microflora. These include:

• Proper oral hygiene.
• A thoughtful diet with a high amount of protein foods and reduced consumption of foods containing glucose.
• Quitting smoking and alcoholic beverages.
• Timely examination by the attending dentist for the prevention, diagnosis and treatment of the disease.
• Avoid taking medications, such as antibiotics, without first consulting your doctor.
• If the patient has dentures, then one of the preventive measures will be their regular treatment in a special solution.
