Relapse - repeat, return of clinical manifestations of the disease after a temporary weakening or disappearance. The concept of relapse was used to mean phases of clinical exacerbations mainly infectious diseases in which the return of illness associated with the preservation of the pathogen in the body of the patient after the primary infection. This recurrence is different from reinfection - recurrence of the disease due to re-infection. In the origin and relapse, and reinfection is critical failure emerging immunity (see). Relapse is possible with many infectious diseases, particularly in the abdominal and return (tick and lousy) the tifa, the paratyphoid a and b, dysentery, malaria epidemic hepatitis, brucellosis and other
Currently, the concept of a relapse is used more widely. About relapse say when you re clinical manifestations and non-communicable diseases, if their treatment is not eliminated, the causes of the disease, causing a repetition of its clinical manifestations under certain conditions. So, to talk about a recurrent course of peptic ulcer disease, rheumatism, chronic pneumonia, recurrent (return) forms of schizophrenia, the relapses of malignant tumors. For some diseases relapsing course is so typical that it reflected in their name (relapsing fever, recurrent paralysis).
The designation of the disease as recurrent mean between the periods of the disease recurrence of periods of remission (see), the duration of which in infectious diseases varies from several days to several months, and when noncommunicable - even up to several years. Relapsing course should be distinguished from cyclic when changing recurring clinical phases of the disease occurs without remission.
The severity of clinical manifestations at relapse varies from oligosymptomatic to heavy with the development of complications. Therefore, the treatment of the disease in the phase of recurrence no less responsible than in the first acute phase of the disease, and it is more successful than previously started.
For the diagnosis of recurrence play the most important role anamnesis (see), which set the time and nature of primary manifestations of the disease and the frequency of its course.
Prevention of the recurrence of infectious diseases in a large extent depends on the correct treatment of diseases in their acute phase, primarily from the selection of antibacterial drug, dosage and duration of appointment. A big role play activities, contributing to the formation of immunity - balanced diet, antisense remedies, vitamins, restorative procedures, in some cases, the use of vaccines.
In cases prone to relapses in certain seasons of the year, applies seasonal prevention of relapse in Russia, for example, the prevention of relapse in people suffering from rheumatism, is held in spring and autumn (application bicillin with anti-inflammatory drugs). If the seasonal character of recurrence is set by the anamnesis of the patient with peptic ulcer disease, 2-3 weeks before the intended start of relapse patient should stricter than in remission, diet, reception alkaline mineral waters, belladonna, vitamin preparations. Such preventive measures prevent the development of recurrence or significantly reduce the degree of its clinical manifestations. The possibility of preventing relapses and reduce their weight with early treatment necessitates follow-up of patients with relapsing forms of diseases (si. Prophylactic medical examination). Depending on the nature of the disease the patient is in remission given medical advice as a General-regime, diet, preventive medications, and so on, for the correct implementation of which is monitored nurse.
