Infectious erythema - causes and signs of infective erythema

There are several types of infectious erythema. Among them:

• Rosenberg - common in school-age children and adolescents;
• Chamera - the causative agent is parvovirus;
• nodular - can be a concomitant disease of tuberculosis, rheumatism;
• multiform - in most cases caused by infectious viral microorganisms;
• sudden;
• migrating - can spread through a tick bite or be one of the manifestations of Lyme disease;
• undifferentiated - a group of infectious diseases of unclear etiology.

Causes

The following sources of development of this disease are assumed: viral infections, reduced immunity, communication with a sick person, prolonged exposure to the sun, genetic predisposition, circulatory disorders, allergic reactions, constant friction of the skin on clothing, exposure to cold, exposure to chemicals, use of drugs, colitis during pregnancy.

The conditions that cause such a disease have not been clarified to date. The irritant is defined only for the following three variants: sudden, Rosenberg's erythema and Chamer's erythema.

Symptoms

Each form has its own specific features.

Rosenberg's signs: septicemia, intoxication (headaches, insomnia); abundant spotted or maculopapular rash, which is localized on the extensor surfaces of the limbs and on the buttocks; disappearance of spotted erythema within 6 days, followed by peeling of the outer shell of the body; enlarged liver and spleen.

Chamer's manifestations: rash on the face, trunk, limbs; at first the rash is represented by small spots, and then acquires a butterfly pattern; neoplasms fade from the middle; their "life" is up to 2 weeks; inflammatory currents of the upper respiratory tract; conjunctivitis; adults are more often ill; swelling of the cartilaginous joints; pain in the head.

Presentation of the nodular image: manifestation of infectious inflammations (tuberculosis, etc.); elevated body temperature; pain in the arms and legs, especially in the knees; pimples appear on symmetrical areas of the epidermis of the forearm and shins, less often on the thighs and feet; occur in the shell of dense nodes that hurt when pressed; connections persist up to 3 weeks; in the depth of the dermis - infiltrate; the cover over the nodes is initially red, and then becomes a greenish-yellowish tint.

Signs of erythema multiforme: chills; headaches, weakness; vesicular formations with transparent contents; when the blisters burst, a red abrasion is formed, covered with a brown crust; at the site of acne - itching, burning.

Signs of a sudden subtype of the disease: elevated body temperature; rashes on the face, trunk, arms; the affected areas consist of small pale pink spots that can merge; neoplasms disappear after 3 days; after recovery, the epithelium peels and pigments.

Clinical picture of the migratory type: at the site of a tick bite - annular erythema appears, which quickly grows and lasts up to 2 weeks; the formations disappear after treatment of the underlying disease, i.e. Lyme disease.

Symptoms of an undifferentiated variant: fever; headaches, drowsiness; rashes that are not typical for other variants of the disease.

Diagnostics

Clinical and laboratory diagnostics are extremely difficult.

If you have the above symptoms, you should consult a dermatologist, pediatrician, or infectious disease specialist.

The following tests are prescribed to establish an accurate diagnosis: serological testing, blood tests, body surface scrapings, and histological examinations.

Treatment

Treatment for all types of infectious erythema is the same. It includes:

• bed rest;
• drinking plenty of fluids;
• anti-infectious drugs;
• antibacterial therapy;
• antihistamines;
• corticosteroid medications (in severe cases);
• avoid sun exposure;
• limit hot baths.

Prevention

Basic measures to prevent this ailment have not been developed to date.

Prevention of this disease may include the following: observing hygiene rules; using only your own hygiene products; proper nutrition; adequate sleep; avoiding contact with sick people. If you notice any of the above symptoms or if you have the slightest doubt about the nature of the abnormalities observed in your body, you should immediately consult a doctor.
