ABSTRACT

The content of lactoferrin (LF) was studied in the liquor and blood of patients with tick-borne encephalitis (TBE) of the meningeal and focal types; additionally, the information density of the discussed parameter was assessed for evaluating the severity and degree of the inflammation process in the central nervous system (CNS). The LF level was determined in liquor of 37 samples obtained from TBE patients (main group) and of 10 persons with osteochondrosis (controls); it was also determined in the serum taken from 21 TBE patients and from 40 healthy donors by using the immune-enzyme analysis. The LF concentration in TBE patients was found to exceed the normal value by 1.5-3 times during the whole observation period. As for the liquor, it was high, by the onset of the disease, by more than 20 times, however, after the 7th day it was higher 6-fold. A direct dependence of a concentration of the studied protein on a form and severity of the disease was established. The LF level in the liquor of TBE patients alongside with clinical signs can be an objective indicator of a severity and activity of the inflammation process in the CNS; it can also be a criteria of how much the conducted therapy effective is.

ABSTRACT

In tick-borne encephalitis certain immunopathological reactions develop in the tissues of the central nervous system; alpha 2-macroglobulin may serve as the marker of the activity of these reactions. The dynamic study of liquor taken from 16 patients with the meningeal and focal forms of tick-borne encephalitis (TBE), 8 patients with severe craniocerebral traumas accompanied by meningitis and 10 patients with osteochondrosis was made. As revealed in this study, in TBE patients the level of alpha 2-macroglobulin increases 3.5-fold and remains stable during the acute period of the disease.

ABSTRACT

In 1985-1989 the etiological structure of acute bacterial meningitides (ABM) in children was studied in 4 largest industrial cities in different regions of the European part of the former USSR, as well as in 2 industrial cities of western Siberia. Due to the common methodological approach used in all investigations, comparable data were obtained in all cities. These investigations revealed that meningococci caused 53.0-86.7% of all cases of ABM in children, which corresponded to moderately increased morbidity rate in meningococcal infection (3.9-11.0 cases per 100,000 of the population, mostly 5.0-7.0 cases) in these cities with its progressive decrease during 3-4 years of observation. The gradual change of meningococci from group A, prevailing in the '70s and early '80s, to group B and in some cases the appearance of group C meningococci, accompanied by a decrease in morbidity rate, were noted. In St. Petersburg the indices of ABM morbidity in children aged up to 5 years for 1987 and 1988, caused by Haemophilus influenzae (0.74 and 4.13) and pneumococci (3.23 and 4.86), could be calculated. A great number of ABM cases of unclear etiology (15.9-33.3%) suggests that the number of ABM cases caused by these two infective agents was underestimated.

ABSTRACT

The coagglutination test with concentrated urine was tried in 59 patients with validated generalized forms of meningococcal infection and in 23 ones with meningitides and pneumonia of a different etiology to assess the diagnostic value of this test. Positive results were obtained in 64.4% of the test group patient and in 4.3% of the reference patients (in a case with pneumococcal meningitis). The antigen serologic group in the urine coincided with the serologic group of the meningococcus that induced the disease in only 19 (50%) of the 38 patients in whom antigenuria+ was detected. In the rest cases urine samples reacted parallel with 2-7 antisera, in 5 patients with the antisera heterologic towards the serologic group of the meningococcus responsible for the disease. Antigenuria was observed between the second and ninth days of the illness, its peak was recorded on days 4-6. Repeated urine tests are more likely to yield positive results. The authors come to a conclusion that the test is simple and harmless for patients, but the presence of false positive results permits regarding it as but an auxiliary one.
