Scleroma

Scleroma is a chronic infectious disease caused by the bacterium Klebsiella rhinoscleromatis. It is characterized by microscopic changes in tissues, including fibrosis and macrophage reaction, leading to the formation of a characteristic granuloma. Scleroma manifests itself mainly in the upper respiratory tract and, in particular, the nose, causing symptoms such as rhinitis, respiratory distress and nasal deformity. The disease occurs predominantly in tropical and subtropical countries and most often affects people with a weakened immune system, creating a problem for their health and quality of life. Diagnosis and treatment of scleroma require a comprehensive approach, including clinical observations and laboratory tests.

History of the disease and interesting historical facts

Scleroma was first described in the late 19th century. In 1895, Paul Roberts, a French physician, observed the clinical manifestations of this disease, attaching particular importance to it as a public health problem. At first, it was believed that scleroma was only endemic, but over time it was discovered that this disease occurs in different regions of the world. In the 20th century, research focused on the etiology and pathogenesis of the disease, which allowed us to better understand the mechanism of its development and find ways to successfully treat it. However, at present, many issues related to the prevention, diagnosis and therapy of scleroma remain relevant, since the incidence continues to be a concern for doctors.

Epidemiology

Epidemiological studies show that scleroma is predominantly endemic, occurring most frequently in countries with hot climates and high levels of population migration. The highest incidence rates are recorded in countries such as Nigeria, Mali and Tanzania. According to the World Health Organization, the incidence rate is about 1-2 cases per 1000 population in regions where scleroma is endemic. According to recent data, the annual number of new cases in some of these countries may reach 20,000. It is important to note that the risks of infection also vary among different population groups, due to living conditions, hygiene and access to health services.

Genetic predisposition to this disease

Genetic predisposition to scleroma is not yet well understood. Research suggests that mutations in certain genes associated with the immune response may increase the risk of developing the disease. The focus is on genes involved in macrophage function and inflammatory responses, such as IL-10 and TNF-α. Inherited mutations in these genes may result in an insufficient immune response to Klebsiella rhinoscleromatis infection, which in turn may contribute to an easier development of scleroma. In some cases, it has been noted that diseases caused by other microbes may coincide with the clinical picture of scleroma, indicating the possible influence of genetic factors.

Risk factors for the development of this disease

Risk factors that contribute to the development of scleroma include:

• Living in endemic areas where the disease is widespread.
• Weak immune status associated with HIV infection or other immunodeficiency conditions.
• Lack of access to medical care and poor hygiene.
• Contact with infectious agents in living conditions.
• Chronic diseases of the nasopharynx, which can contribute to the development of infection.

Understanding these factors is important for targeted preventive measures and the development of effective strategies to combat this disease.

Diagnosis of this disease

Diagnosis of scleroma is a multi-step process that relies on clinical evaluation and laboratory testing. The main symptoms include:

• Chronic rhinitis.
• Deformation of the nose and hypertrophy of the nasal passages.
• Difficulty breathing.
• Skin manifestations in the affected area.

To confirm the diagnosis, the following laboratory tests must be carried out:

• Cytological examination of tissue wear revealing characteristic granulomas.
• Immunological tests for the detection of antibodies to Klebsiella rhinoscleromatis.

Radiological examinations such as X-rays or CT scans can help assess the extent of tissue changes. Additional diagnostics include endoscopy, which allows visualization of the affected areas and the collection of biopsy material. An important step is differential diagnosis, which allows the exclusion of other upper respiratory tract infections such as syphilis, tuberculosis, and other granulomatous diseases.

Treatment

Treatment of scleroma may vary depending on the stage of the disease and the severity of symptoms. General treatment includes:

• Use of antibiotics such as doxycycline and ciprofloxacin to control the infection.
• Immunotherapy to correct the immune response.

Pharmacological treatment often includes:

• Anti-inflammatory drugs to relieve inflammation.
• Immunosuppressants for severe and resistant forms of scleroma.

Surgical treatment may be required in cases of severe nasal deformity, when it is necessary to establish normal breathing. In some cases, correction of the nasal structures or other reconstructive surgeries are performed. Alternative treatments such as physical therapy may also be considered.

List of medications used to treat this disease

Medications used to treat scleroderma include:

• Doxycycline
• Ciprofloxacin
• Prednisolone
• Methotrexate
• Cortecosteroids

This group of drugs is aimed at reducing inflammatory reactions and fighting the infectious agent.

Disease monitoring

Monitoring of scleroma includes regular examinations and assessment of the dynamics of the disease. Control stages may include:

• Assessment of the patient's clinical condition taking into account symptoms.
• Laboratory tests to determine the presence of the pathogen or its antibodies.

The prognosis of the disease depends on timely diagnosis and adequate treatment. In most cases, with the right approach, it is possible to achieve remission, but complications such as repeated infections or chronic changes in the nasal structures may occur, which may require repeated intervention.

Age-related features of the disease

Scleroma can manifest itself in different age groups, but certain age-related features are observed. In children, the disease often manifests itself less aggressively, in addition, they can tolerate surgical interventions more easily. In older people, more pronounced symptoms and the possibility of concomitant diseases are often observed, which complicates the process of diagnosis and treatment. At the same time, there is an opinion that chronic forms of scleroma are characteristic of mature people, where lifestyle and features of the immune system could lead to acceleration of the disease process.
