Volyn fever( trench, trench fever) - Causes, symptoms and treatment. MF.

All rickettsiosis for clinical manifestations, complications and treatment are identical to typhus, but there are specific features:

Volyn fever( trench fever, paroxysmal rickettsiosis) - little studied rickettsiosis( bartonellosis), characterized by repeated attacks of fever against the background of general intoxication, with a rash, myalgia and arthralgia. This disease is more often registered among the inhabitants of the African continent.

Source is a patient whose blood pathogen remains up to 2 years and therefore, with this disease, infection can occur through a blood transfusion. Also, there is information about the air-drop mechanism transmission.

The causative agent of Volyn fever

The causative agent is very stable in the external environment. Tropism to the tissues of the causative agent of Volyn fever is the same as in other Bartonellae( rickettsia): skin, organs of the CMF( spleen, lymph nodes, Kupffer cells, etc.), endocardium, but the most pronounced tropism to bone tissue and this is a distinctive feature - this causes a strongthe pain in the bones is already at the beginning of the disease, and the patients complain of pain in the region of the ribs, the tibia and the tibia.

Symptoms of Volyn fever

The causative agent multiplies mainly in the bone marrow, before the exit of the pathogen into the blood - the temperature is within normal limits, after the release - rise to 39 ° C for 3-4 days, then as the rickettsia leaves the blood, the temperature again is normal3-4 days before the next "splash" of the pathogen, and this temperature drop is sharp, which is accompanied by a sharp weakness and sweating - this type of fever is called a paroxysmal form. These time parameters are gradually reduced, and usually there are 2-4 such attacks, and then the intervals between them increase, and the duration and severity is reduced, and other symptoms are minimized. After the last attack, within 2 weeks, the subfebrile condition may persist.

Unlike other rickettsiosis, the wall of vessels is not involved in the inflammatory process, which explains the relative ease of the flow.

Diagnosis

Nonspecific diagnostics are of little informative, shows only inflammation. The specific reaction of Weyl-Felix is ​​negative, as this antibody does not form antibodies specific for the majority of rickettsiosis;Specific serological reactions are the same as in other rickettsiosis.

Treatment of

Treatment is the same as with other rickettsiosis( described in detail in the article typhus fever).

After the transferred disease, unstable immunity forms.

At the moment there is only nonspecific prevention, which is to combat pediculosis. Specific prevention is not developed.
