Impetigo is a superficial bacterial skin infection caused mainly by staphylococci and streptococci. The pathology is characterized by the formation of vesicles or pustules, which often open over time and form crusts. Impetigo is most often observed in children, but can also occur in adults, especially in the presence of predisposing factors or skin injuries. The disease can be transmitted by contact, especially in crowded conditions, and requires a comprehensive approach to diagnosis and treatment.
History of the disease and interesting historical facts
The history of impetigo goes back centuries. The first mention of the disease dates back to ancient medical texts, which describe symptoms similar to modern manifestations of impetigo. Medical literature from the 18th century mentioned various methods of treatment, including the use of honey and herbal infusions. An interesting fact is that in different historical eras, impetigo was a well-known disease, perceived as a "boyar disease", due to the frequent defeat of children of the upper classes, which is associated with the high level of hygienic standards in their environment. Epidemics of this disease have been recorded throughout history, which confirms its prevalence and susceptibility in various populations.
Epidemiology
Epidemiological studies show that impetigo is one of the most common infectious skin diseases, especially among children. According to the World Health Organization, the incidence of impetigo in the child population reaches 3-10%, depending on the region. In some disadvantaged areas, this figure can increase to 20-30%. Preschool children are most susceptible to the disease, especially those who study in child care institutions. In developed countries, cases of impetigo are more common in the summer months, while in developing countries, where compliance with sanitary and hygienic standards is difficult, cases are recorded all year round.
Genetic predisposition to this disease
Research suggests that there is a genetic predisposition to impetigo, although it has not been clearly described. Certain mutations in genes involved in the functioning of the immune system may increase susceptibility to infections. This is especially true for genes that regulate antibody production and the functionality of immune system cells. Given that skin picking or previous skin conditions (eczema or dermatitis) increase the likelihood of developing impetigo, some cases may be considered to have a genetic basis, indicating certain genetic abnormalities among family members.
Risk factors for the development of this disease
The most significant risk factors for impetigo include:
- Violation of the integrity of the skin (cuts, abrasions, burns).
- Poor sanitary living conditions, including inadequate hygiene.
- Contact with carriers of bacteria (for example, in kindergartens and schools).
- Chronic skin diseases (eczema, dermatitis).
- Reduced immune status (including blood diseases, diabetes and other concomitant diseases).
- Seasonal exposure (summer months).
Diagnosis of this disease
Diagnosis of impetigo is based on clinical manifestations and laboratory data. The main symptoms of the disease include:
- Formation of vesicles and pustules on the skin.
- Itching and inflammation of surrounding tissues.
- Bloody crusts on the surface of the skin.
- General malaise in case of extensive damage.
Laboratory investigations may include microbiological culture of pustule contents with antibiotic susceptibility testing. Radiological examinations are not generally required except in complicated cases of infection. Differential diagnosis includes conditions such as folliculitis, eczema, and herpes.
Treatment
Treatment of impetigo directly depends on its form and severity. In mild cases, local antibiotics such as mupirocin or fusidic acid are used. In more severe forms, including extensive lesions, systemic antibiotic therapy is indicated. Surgical intervention may be required in cases of abscesses or furuncles. An important component of therapy is maintaining hygienic measures and preventing re-infection.
List of medications used to treat this disease
The list of the most frequently used means includes:
- Local antibiotics: mupirocin, fusidic acid.
- Systemic antibiotics: ciprolet, amoxicillin with clavulanate.
- Medicines for the treatment of concomitant skin diseases (antimycotic and anti-inflammatory drugs).
Disease monitoring
Monitoring of the patient's condition includes regular assessment of the treatment dynamics, as well as possible control joints 7-10 days after the start of therapy. The prognosis is generally favorable, but complications such as osteomyelitis or recurrent infections are possible. Constant monitoring of the skin condition and compliance with the doctor's instructions help minimize the risk of relapses.
Age-related features of the disease
Impetigo is generally more common in children, especially those under 6 years of age. In adults, the disease may develop during exacerbation of chronic diseases or in conditions of poor hygiene. In older people, cases of the disease may be associated with a weakened immune system and concomitant pathologies such as diabetes or heart disease.
Questions and Answers
- How is impetigo transmitted? Impetigo is transmitted by contact, through directly infected skin, as well as through personal hygiene items.
- What are the symptoms of impetigo? The main symptoms include blistering skin rashes, itching, redness and inflammation of the surrounding tissues.
- Can you get impetigo from clothing? Yes, the infection can be spread through shared items such as towels or clothing if they have been in contact with affected skin.
- How long does it take to treat impetigo? In most cases, treatment lasts for 7-10 days and includes the use of antibiotics and personal hygiene.
- How to prevent recurrence of the disease? Maintaining personal hygiene and avoiding contact with carriers of the infection are the main preventive measures.
Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov recommends the following for the treatment and prevention of impetigo:
- Maintain personal hygiene: wash your hands regularly and remove damaged skin areas.
- If there are open abrasions or wounds, use special antiseptic agents.
- If symptoms appear, do not delay in contacting a doctor to receive proper treatment.
- Avoid physical contact with sick people and do not share items until you are sure there is no infection.
Correct information and adherence to preventive measures will help reduce the risk of the occurrence and spread of impetigo among the population.
