Definition

Several types of bacteria and fungi typically live and grow on the skin in small quantities, contributing to the maintenance of the skin's defensive balance. Most of these microorganisms are harmless. However, infections may come up if these organisms begin to proliferate uncontrollably.

The fungus Candida sp. represents one of these potentially harmful microorganisms. When it excessively colonizes the skin, nails, or hair, a fungal infection known as cutaneous candidiasis may develop.

Cutaneous candidiasis generally manifests as a red, itchy rash, frequently occurring in the folds of the skin. This rash may also extend to other parts of the body. Although the symptoms can be bothersome, this infection is treatable through proper skin hygiene and the application of antifungal creams or powders.

 

Cutaneous Candidiasis in Babies

Cutaneous candidiasis is a prevalent infection among infants. Diaper rash associated with candidiasis is one of the most common Candida infections observed in this age group. This rash typically presents as a red rash with well-defined borders and often persists for more than three days. Treatment strategies include frequent diaper changes and the use of loose-fitting clothing.

Another common manifestation in newborns and infants under six months is oral thrush. Symptoms may include cracked skin at the corners of the mouth and whitish patches on the lips, tongue, or inside the cheeks. Antifungal medications prescribed by a doctor can be applied to the affected areas in the baby's mouth. If left untreated, thrush can spread throughout the body via the bloodstream. It is important to consult a doctor if a baby develops thrush.

 

Cutaneous Candidiasis in Children

While healthy children generally possess robust immune systems, studies have indicated that the incidence of fungal skin infections in children can increase rapidly. Children may develop thrush following the use of antibiotics to treat other illnesses.

Children who persist in thumb-sucking are at a higher risk of developing thrush around their nail beds. If a child aged nine months or older experiences recurrent thrush or skin infections, it may signal an underlying health issue, such as HIV or another immune disorder. Older children with recurrent or severe skin infections should be evaluated for diabetes mellitus.

 

Causes

Cutaneous candidiasis occurs when the skin becomes infected with the Candida fungus. Although small amounts of Candida normally reside on the skin, uncontrolled proliferation can lead to infection. Several factors can trigger cutaneous candidiasis, including:

  • Prolonged exposure to wet or moist skin conditions
  • Warm and humid environments due to tight clothing
  • Poor hygiene and infrequent changing of underwear
  • Obesity
  • Antibiotic use, which can eliminate the normal bacteria that keep Candida under control on the skin
  • The use of corticosteroids or other immunosuppressive medications, which weaken the immune system
  • Medical conditions such as diabetes, pregnancy, or other conditions that impair immune function

The Candida fungus thrives in warm, moist environments, which is why infections frequently occur in skin folds. Infants are also susceptible, particularly on the buttocks, as diapers provide an ideal environment for Candida growth.

Cutaneous candidiasis is generally not contagious. However, individuals with weakened immune systems may contract candidiasis after coming into contact with the skin of an infected person. Such individuals are also at an increased risk of developing more severe candidiasis infections.

 

Risk Factors

Cutaneous candidiasis can develop in almost any region of the body but is more commonly found in areas where skin folds or where two skin surfaces come into contact or rub together, such as the armpits, groin, and the spaces between fingers and toes.

Fungi thrive in warm, moist, and sweaty environments. Typically, the skin serves as a robust barrier against infections; however, any wound or damage to the skin can provide an entry point for fungi to infect the underlying tissue.

The Candida fungus can become pathogenic and cause disease when environmental conditions favor its growth. These conditions include hot and humid weather, poor hygiene practices, and wearing tight clothing.

Candida infections are more prevalent in individuals who are:

  • Overweight or obese, as they tend to have more skin folds
  • Diabetic
  • Suffering from hypothyroidism, a condition where the thyroid gland produces insufficient thyroid hormone
  • Experiencing immune system disorders
  • Working in humid environments
  • Pregnant
  • Taking certain medications, such as topical corticosteroids, antibiotics, and oral contraceptives

Individuals taking the aforementioned medications should regularly monitor their skin for signs of cutaneous candidiasis.

 

Symptoms

The primary symptom of cutaneous candidiasis is a rash, often characterized by intense redness and itching. In certain cases, the infection can lead to cracked, painful skin, the formation of blisters, or the appearance of small, pus-filled bumps.

While the rash can develop on various parts of the body, it is most commonly found in skin folds, such as the armpits, groin, between the fingers, or beneath the breasts. Candida may also cause infections in the nails, nail beds, and corners of the mouth.

 

Diagnosis

A diagnosis of cutaneous candidiasis can often be made by a doctor through a physical examination. The physician will assess the location and appearance of the rash. In some cases, a skin culture may be performed to confirm the diagnosis.

During a skin culture, the physician swabs the affected area to collect a skin sample, which is then sent to a laboratory for testing to detect the presence of Candida fungus.

 

Management

Initial treatment of cutaneous candidiasis can often be managed with home remedies. Maintaining clean and dry skin is crucial to prevent moisture accumulation, which can foster the growth of Candida.

Several lifestyle modifications can aid in both preventing and treating candidiasis infections, including:

  • Promptly changing wet clothing, such as swimsuits or sweaty workout attire
  • Regularly changing socks and underwear
  • Wearing loose-fitting garments
  • Using mild, fragrance-free soap on the affected areas
  • Taking probiotics
  • Adopting a low-sugar diet

Since elevated blood sugar levels can contribute to the development of Candida infections, controlling blood sugar can help alleviate symptoms. Lowering blood sugar levels through a low-sugar diet and exercising for at least 30 minutes three times per week is recommended. Individuals with diabetes should adhere to medical advice regarding diabetes management.

In cases of severe or recurrent candidiasis, a physician may recommend the use of topical antifungal creams or powders. Common over-the-counter antifungal creams include clotrimazole, miconazole, and tioconazole. If these are ineffective, the doctor may prescribe stronger antifungal creams such as nystatin or ketoconazole.

If the infection has spread to other parts of the body, such as the throat or mouth, oral antifungal medication may be required.

Cutaneous candidiasis typically resolves with appropriate treatment, and most cases completely clear up without complications. Treatment usually leads to resolution within one to two weeks, depending on the infection's severity. However, recurrences are possible if the patient is exposed to triggering factors.

Individuals with weakened immune systems, particularly those undergoing chemotherapy or living with HIV/AIDS, face a significantly higher risk of developing severe or potentially life-threatening Candida infections. If someone undergoing chemotherapy or living with HIV/AIDS experiences severe symptoms such as a sore throat, headache, or high fever, they should seek medical attention immediately.

 

Complications

Complications arising from cutaneous candidiasis include:

  • Nail infections that can result in abnormal nail shapes and the spread of infection around the nail.
  • The likelihood of recurrent Candida skin infections if exposed to risk factors.
  • The occurrence of widespread candidiasis, particularly in individuals with weakened immune systems.

 

Prevention

To minimize the risk of Candida infection, several simple steps can be taken:

  • Avoid excessive moisture on the skin.
  • Wear clothing that absorbs sweat and prevents the skin from becoming damp.
  • Keep areas prone to infection, such as the armpits and groin, clean and dry.
  • Always shower and thoroughly dry the body after activities that induce sweating.
  • For individuals who are overweight or obese, it is essential to keep skin folds dry.
  • Opt for sandals or open-toed shoes in warm weather.
  • Regularly change socks and underwear.

Clinical trials involving infants aged 3–15 months have shown that using sweat-absorbing diapers compared to traditional ones can reduce Candida infection rates by nearly two-thirds. Additionally, antibiotic use in infants increases the risk of Candida infection. Therefore, antibiotic administration should always adhere to medical guidelines to prevent Candida infections.

 

When to See a Doctor?

It is advisable to consult a doctor if symptoms of cutaneous candidiasis appear before the infection spreads and leads to complications.
