Candidiasis in infants: causes of development, nature of manifestation and general principles of treatment of the disease

Who's at risk

First of all, these are people who have the following unfavorable factors:

1. Weakened immunity.

Defects in immune defense are the main factor predisposing to the occurrence of mycoses (fungal infections)1,2,4. The increase in their incidence in all countries of the world is due, first of all, to various types of conditions accompanied by weakened immunity1,[3]. It is not for nothing that “thrush” is called “the disease of the sick”1. Among its reasons:

• severe general diseases, for example, infectious2,3;
• cancer accompanied by sudden weight loss, lack of vitamins and microelements, requiring radiation and chemotherapy2,3;
• congenital and acquired forms of immunodeficiency, including AIDS2,3;
• endocrine disorders, for example, diabetes mellitus2,3.

1. Dental diseases.

• Inflammatory , such as caries and its complications, gingivitis, periodontitis, periodontal disease and others2. The huge number of bacteria present during inflammation weakens the immune system and contributes to the proliferation of fungal microflora2. A diseased tooth with a carious cavity “infested” with microbes or a periodontal pocket filled with pus may well provoke the development of “thrush”3,[4].
• Non-inflammatory , which change the structure of the oral mucosa, for example, folded tongue and leukoplakia4. It is easier for fungi to attach to a damaged surface than to a healthy one.

1. Constant dry mouth.

• Insufficient saliva (xerostomia), associated with a variety of problems, contributes to the development of oral mycosis4. Saliva contains many enzymes and antibodies that protect the mucous membrane from the action of microbes4. If there is little saliva, it dries out, its protection is weakened, which creates favorable conditions for the development of other infections.

1. Defects in oral hygiene.

• Insufficient care . Problems more often arise in those who rarely brush their teeth and ignore the care of their tongue, interdental spaces and dentures4.
• Injuries . Sometimes the cause of an “outbreak” of oral mycosis is a too hard toothbrush or rough manipulation of dental floss and toothpicks. Injured gums are easy prey for fungi2.3,4.

1. Incorrect use of removable dentures.

• Poorly customized removable dentures can rub the gums3,4, making them accessible to germs.
• No night break in using prostheses4. The gum located under the prosthesis is poorly enriched with blood, it lacks oxygen, it is not washed with saliva - this predisposes to the development of infection4.
• Improper care of dentures. Artificial teeth need care just as much as your own. Deprived of attention, they become covered with a thin film of various microbes, which then “attack” the gums.

1. Age.

• Most often, doctors find “ thrush” in the mouth of infants and the elderly4. The reason for this is the imperfections of the immune system, which create favorable conditions for the proliferation of pathogenic microflora1,4,[5]. In addition, in childhood, dietary habits affect, and in old age – constant dry mouth and lack of teeth, forcing you to wear dentures1,5.

1. Medicines

• Antibiotics. They kill not only pathogenic microbes, but also beneficial ones, thereby disturbing the balance of microflora and creating conditions for mycoses to flourish1,2.
• Drugs that inhibit cell proliferation (cytostatics). They interfere with the renewal of surface mucosal cells and disrupt local and general defense mechanisms against infections1,2.
• Immunosuppressive medications, which are prescribed when immune responses need to be suppressed, such as during transplantation1,2.
• Inhaled corticosteroids, which are used in the treatment of bronchial asthma and, due to their side effects, increase the susceptibility of the mucous membrane to infections2,[6].

1. Unbalanced diet

• Lack of iron, vitamins C and B12, and folic acid1 in the diet, which leads to decreased immunity.
• Excess carbohydrates1,2. Excessive consumption of sweets, flour products, sweet fruits, starchy vegetables and other foods containing large amounts of simple carbohydrates contributes to the appearance of thrush in adults and children1,2.

What does thrush look like in the mouth - its symptoms in adults

After Candida attaches to the mucous membrane, they multiply and “grow” deep into it2, causing inflammation, swelling and redness. There is a feeling of a “scalded mouth” and discomfort when eating and swallowing. There may be a change in taste and the appearance of a metallic, sour, salty or bitter taste1.

The proliferation of the fungus leads to the appearance of small white spots on the gums, tongue, inner surface of the cheeks and palate, reminiscent of curdled milk or grains of semolina porridge. Increasing in size, the “grains” turn into plaques, which, in turn, merge to form solid white films.

If plaques and films are removed with a spatula or a cotton swab (this does not require additional effort), then a bright red inflamed, eroded mucous membrane is revealed underneath them.

Oral mycosis can spread to the red border of the lips , causing redness, dryness and peeling. Seizures appear in the corners of the mouth: the skin becomes inflamed, covered with grayish-white scales and cracks5.

If candidiasis is not treated at this stage, the fungi “spread” to the tongue and pharyngeal tonsils.

When the tongue is damaged, glossitis develops - the tongue swells, its papillae are smoothed out, a characteristic white coating appears on its back and lateral surfaces1 - and when the pharyngeal tonsils are damaged, a sore throat occurs.

A sore throat caused by fungal microflora is very different from normal. With obvious inflammation of the tonsils and the presence of white films and plugs on them, there is no temperature or pain when swallowing, and the submandibular lymph nodes remain of normal size1.

Candidiasis can spread further - affecting the respiratory tract, causing pneumonia and blood poisoning, so it is important to stop the process at the very beginning.

Symptoms

A number of symptoms are characteristic of candidal stomatitis:

• The appearance of a white or yellowish coating on the tongue, cheeks or palate. When trying to eliminate it, bleeding wounds may appear on the mucous membrane.
• Constant metallic taste.
• Feeling of heartburn on the tongue.
• Painful sensations from touching plaque.
• Later, as plaque spreads, difficulty swallowing occurs.
• Deterioration of tongue sensitivity and poor taste perception.

Features of “thrush” in the mouth in children of the first year of life

Mycoses in children, and very young ones at that, are not that uncommon. According to statistics, the first illness of a newborn in 33% of cases is associated with Candida fungi5. Moreover, they mainly affect the skin and tissues of the oral cavity5.

Why does thrush appear in the mouth of a child under one year old?

Mycotic stomatitis, or fungal inflammation of the oral mucosa, is the most common form of mycosis in children under one year of age1.5. How do mushrooms get into a baby’s mouth and why do they take root there? There are many reasons for this.

• Infection during childbirth.

During childbirth, the fetus comes into contact with the microflora of the woman’s vagina. If the mother suffered from vaginal candidiasis before giving birth and did not undergo the necessary course of treatment, the baby has every chance of inheriting a large amount of the causative agent of this disease1.5, which is a big burden for the immature immune system. According to statistics, on the first day of life, Candida fungi are found in the oral stool of 25-40% of newborns5.

• Unsanitary conditions.

Infection is possible due to violation of the rules of care for the newborn and defects in the hygiene of the nursing mother herself1,5. The infection is transmitted through dirty nipples and hands during feeding, through toys, nipples, dishes and linen.

• Imperfect immunity1, 5.

In a baby under one year old, the immune system is only “gaining experience”, because in the womb it did not come into contact with the infection and therefore “did not learn” to fight it.

• Prematurity and illness.

Candida can only harm a weakened body. The best conditions for their development are created if the birth occurs before term, the fetus is premature and/or has developmental defects or congenital diseases5.

• Nutritional features.

The threat is posed by regurgitation, the habit of putting the baby to bed with a bottle of milk and feeding with sweet artificial formulas. If milk remains in the mouth, which also contains a large amount of sugar, it becomes an ideal breeding ground for mushrooms.

• Features of salivation.

Due to physiological characteristics, the salivary glands of infants produce little saliva1 - they simply do not need it, since food is already liquid. At the same time, saliva has antifungal activity, and when there is little of it, the likelihood of oral thrush in a newborn increases1,5.

What does oral candidiasis look like in children?

The symptoms are the same as in adults: first, white “grains” appear on the mucous membrane, then “clumps” resembling curdled milk, and white films1. The difference is that the process is almost always accompanied by severe tissue swelling and the formation of numerous painful ulcers on the oral mucosa and tongue1,5. Therefore, due to oral thrush, infants often refuse to eat5.

In children, a fungal infection can affect not only the tonsils (tonsillitis), but also the pharynx (pharyngitis) and larynx (laryngitis). If the larynx is affected, the baby's voice becomes hoarse and low, and there is a risk of swelling of the airways and breathing problems1, 5.

Clinical treatment

The success of treatment of candidal stomatitis in children can only be said if all sources of infection have been completely eliminated. When the cause of oral disease is the use of antibiotics, in parallel with general treatment, a course of antifungal therapy may be prescribed.

The principle of treating candidal stomatitis in children comes down to creating an alkaline environment in the oral cavity - it is this pH value that is detrimental to fungi. In addition, in an alkaline environment, most pathological microorganisms die, including those that cause carious tooth decay.

The child’s oral cavity can be treated with a solution of baking soda (the optimal concentration will be determined by the attending physician). The procedure for treating candidal stomatitis in children is quite simple: a gauze swab soaked in a solution is used to treat the oral mucosa of the gums and cheeks.

In severe cases, your dentist may prescribe oral medications.

The Doka-Dent dental clinic provides quick and safe diagnostics for effective treatment of stomatitis in infants and older children. Branches in Moscow are located at two addresses:

1. Teply Stan district, Leninsky Prospekt, building 131, 1st and 2nd floor. One minute from Troparevo metro station in a building located between Leninsky Prospekt and Academician Bakulev Street.
2. Tverskoy district, 1st Tverskaya-Yamskaya, building 27, 2nd floor. Three minutes from any exit from Belorusskaya station in a building located between the first Tverskaya-Yamskaya and the first Brestskaya streets.

Specialists from both clinics conduct examinations free of charge and help urgently prevent the development of complications and the spread of the disease!

Diagnosis of oral mycosis

Most often the diagnosis is obvious. However, in difficult situations, for example, in the presence of complications or individual intolerance to certain drugs, to confirm it, microscopic and cultural analysis of scrapings from the surface of the mucous membrane is used to determine the sensitivity of the microflora to antifungal drugs. Moreover, the mere presence of Candida threads in scrapings from the oral cavity is not always enough to make a diagnosis - fungi can be present in the mouth, but not cause any diseases. In such a situation, quantitative assessment is important, that is, counting the pathogen cells, and increasing their number when re-analyzed after 2-3 days.

What kind of disease is candidiasis?

According to statistics, about 30% of infants experience candidiasis. The causative agent of the disease is Candida fungus. These specific microorganisms are normally present in the body of every person, even in the absence of health problems, but only in small quantities.

Oral candidiasis in children is much more common, since the immune system of children is not yet formed and is not able to resist pathogenic microorganisms and the effects of negative external factors.

With weakened immunity and the concomitant influence of provoking factors, the fungus begins to actively multiply, affecting the mucous membranes. Without therapeutic treatment, candidiasis is eliminated in exceptional cases. Much more often, if thrush is not treated, complications arise, and the infection itself spreads throughout the body.

How and with what to treat thrush in the mouth

Since candidiasis often develops as a secondary disease1, treatment of oral thrush requires an individual approach. What do we have to do?

1. Eliminate the factors that contributed to the appearance of oral mycosis

To do this you need:

• cure diseased teeth and gums, relieve exacerbation of chronic tonsillitis, pharyngitis;
• replace old “outdated” removable dentures with new ones, follow the rules for using and processing dentures;
• every time after using inhalers with steroid drugs (for bronchial asthma), rinse the mouth and gargle with water6;
• take antibiotics only as prescribed by a doctor;
• use toothbrushes with soft bristles, toothpastes, and mouthwashes with an anti-inflammatory effect1;
• follow the rules of caring for a newborn and feeding hygiene (if the disease manifests itself in an infant);
• use formulas that do not contain sugar for artificial feeding of a newborn.

2.Keep a diet

Meals include:

• limiting the daily intake of simple carbohydrates: sweets, flour products, potatoes, rice, legumes, boiled beets and carrots, sweet fruits and dried fruits;
• supplementing the diet with fresh vegetables with a lot of fiber, which contribute to the formation of normal microflora in the intestines and the formation of immunity9;
• consumption of sour berries and lactic acid products, which, due to their acid content, hinder the spread of fungi1;
• taking vitamins1 necessary for the normal functioning of the immune system;
• eating enough easily digestible meat and eggs for the normal functioning of the immune system.

3. Carry out local treatment

For oral thrush in both adults and children, treatment may include topical use of drugs with antifungal activity. Moreover, if the fungus affects only the oral cavity, local therapy may be sufficient5 to cope with the problem.

To treat the oral mucosa, today it is recommended5 to use hexetidine preparations, for example, HEXORAL® solution and HEXORAL® aerosol .

HEXORAL® with hexethidine:

• is active against biofilms[7] that are resistant to other drugs, and is harmful to fungi of the genus Candida, which cause oral candidiasis;
• has a high safety profile;
• can be used not only in adults, but also in children from 3 years old8;
• eliminates discomfort and relieves pain7;
• lasts for a long time, up to 12 hours[8];
• Available in the form of a solution and an aerosol, for comfortable use in any situation (for fungal laryngitis in children, it is especially convenient to use the aerosol form of the drug)2.

Important: doctors prescribe general antifungal drugs only if local treatment is ineffective and multiple relapses of candidiasis occur against the background of severe immunodeficiency and/or severe concomitant diseases. In these cases, HEXORAL® can be an addition to the main therapy1, 2, 5.

When treating oral thrush in newborns, there is often no need to use systemic antifungal agents1, 2, 5.

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.

How to prevent the disease

So, what will help avoid an “outbreak” of fungal infection?

• Careful oral care.
• Solving dental problems and treating common diseases.
• Compliance with the rules of personal hygiene, hygiene of infant feeding and care1.
• Mandatory treatment of the disease during pregnancy and after childbirth1.
• Prophylactic use of antifungal agents, for example, during treatment with antibiotics and immunosuppressive drugs (radiation or chemotherapy)1.

Important: frequent outbreaks and severe cases of candidiasis are a reason to consult a doctor and undergo a full examination. Taking into account the fact that mycoses develop against a background of reduced immunity, they can act as a marker of serious diseases2. According to the World Health Organization, recurrent candidiasis should be a reason for testing for HIV.
