Migrating erythema: symptoms and treatment
Migrating erythema is an infectious disease that affects the skin of a person. He begins to progress because of a tick bite, more often of a forest tick. In the medical literature there is also a name for the disease — migratory erythema Afzeliusa Lipshutts.
The danger of chronic migratory erythema is that it can be asymptomatic for a long time, and its causative agent will be in the bloodstream all the time. There is a pathology of the type of dermatosis. The disease affects people from different age categories. Restrictions, concerning sex, he also does not have.
The main cause of the progression of chronic migratory erythema in humans is the tick bite, through which the Borrellia burgdorferi spirochetes penetrate the body. Also, the transplacental route of spirochete transmission is not excluded.
- 1 stage — begins to progress immediately after the bite. The place of the bite turns red and there is edema. The size of the focus is relatively small — it reaches a maximum of 5 cm
- Stage 2 — at this stage, the spot size increases (from 15 cm or more). At visual inspection it can be noted that the central part of the focus is poorly pigmented. Dermal fibrosis begins
- Stage 3 — has two possible variations of the current. The patient can either fully recover, or his condition may become complicated and a CNS lesion will occur.
Symptomatology may not appear for a long time, but the causative agent itself is already in the blood of a person and can cause complications.
The clinical picture of migrating erythema:
- After a bite, a sore spot of circular shape appears on the skin
- As the pathology progresses, the stain also begins to grow rapidly. In diameter, it can be 15-20 cm;
- the spot center is pigmented and acquires a pale red color
- If the bite is localized in the more delicate areas of the skin, then there may be additional symptoms: tingling, burning, itching
- most often the pathological spot is localized in the armpits, on the back, buttocks or in the popliteal areas
- in some cases, the victim’s condition may worsen;
- In severe cases, the causative agent of the disease can cause the development of CNS diseases. Usually, meningitis develops as a complication.
If you have any of the above symptoms after the bite of an insect, you should immediately go to a medical facility for a thorough diagnosis and the appointment of adequate treatment. The examination is conducted by a dermatologist. The standard diagnostic program, with suspicion of migrating erythema, includes such studies:
- Visual examination of the patient and evaluation of his complaints
- serological examination. For analysis, the synovial and cerebrospinal fluid, as well as the blood, can be sampled (serum is needed). This method makes it possible to identify antibodies to the causative agent of pathology;
- Histological examination
- if necessary, the consultation of a neurologist is conducted.
Differential diagnosis is carried out with:
- a linear migratory miase
- the annular erythema of Daria
The optimal treatment plan, which will allow a person to be cured of the disease in the shortest time, is prescribed only by the attending physician on the basis of the results of the tests. In the main therapy necessarily include antibiotics to completely destroy the pathogen. Treatment with these drugs is recommended to be performed only under the supervision of a doctor.
The main treatment plan is complemented by the following drugs and procedures:
- ointments for external use with antibacterial agents and glucocorticosteroids
- Immune therapy
- limit exposure to low temperatures or direct sunlight
- introduction of anti-malignant gamma globulin
In order not to carry out treatment of this disease, it is worth while to take up its prevention. The main direction is to ensure maximum body protection when visiting forests. To this end, you need:
- use chemical insect repellent
- wear long-sleeved clothing
- Closed shoes
- long pants (if possible, they are recommended to fill in socks)
If the tick was still found on the human body, then the skin should be immediately treated with any antiseptic solution, then the insect is twisted. Then you should immediately go to a medical facility for diagnosis, and, if necessary, treat the disease (when confirming the diagnosis).
